Searchalert luggage lock || Richmond Lock and Footbridge

Posted on December 31st, 2007 in Uncategorized by admin

Richmond Lock and Footbridge is a lock and pedestrian bridge, situated on the River Thames in south west London, England. It is the furthest downstream of all the Thames locks and is the only one owned and operated by the Port of London Authority. It was opened in 1894 and is situated close to the centre of Richmond in the south western suburbs of London. It connects Richmond on the east bank with the neighbouring district of St. Margarets on the west bank during the day, but is now closed at night to pedestrians - after 19:30 GMT or after 21:30 when BST is in use.

Description

Technically, Richmond Lock is a half-tide lock and barrage, which also incorporates a public footbrige. The footbridge crosses both the conventional lock and the barrage, which comprises three vertical steel sluice gates suspended from the footbridge structure. These gates weigh 32 tons each and are 66 feet in width and 12 foot in depth. The lock permits passage of vessels up to 250 feet long by 26 feet 8 inches wide.

For about two hours each side of high tide, the sluice gates which make up the barrage are raised into the footbridge structure above, and river traffic can pass through the barrage unimpeded. For the rest of the tidal cycle the sluice gates are closed, and ships and boats must use the lock alongside the barrage. The barrage has the effect of maintaining the water level between Richmond Lock and Teddington Lock (the next lock upstream) at or above half-tide level. The maximum fall of the lock is 10 feet.

Luggage lock key || Coffin lock

Posted on December 22nd, 2007 in Uncategorized by admin

Coffin Lock is a slang term for a blind panel connector (also called a Butt-Joint Fastener) often used in performing arts to join together stage decks or scenery in a butt joint or cabinet and lid locks on road cases. These are typically two part connectors (male and female) that draw together and lock. The two most common types are the cam and acceptor (sold under the trade name “Roto-Lock”) and more traditional hook and pin version. These devices generally use an Allen key to operate the locking mechanism via a small diameter hole either through the face or rear of the panel. When locked, the considerable mechanical advantage offered by the cam or hook holds the panels tightly together. Coffin locks can be installed directly into a mortise cut into each panel, for total concealment except for the locking hole, or mounted to the rear of the panels.

Samsonite lock || Bray Lock

Posted on December 18th, 2007 in Uncategorized by admin

Bray Lock is a lock and weir situated on the northern bank of the River Thames near Dorney, just above the M4 Motorway crossing of the Thames. It is a manned lock, and the lock keepers cottage is on an island between the lock and the weir. It is owned and managed by the Environment Agency. Bray itself and Maidenhead, Berkshire, England are on the opposite side of the river but can be reached from the lock.

Reach above the lock

Along the reach is Maidenhead, preceded by Brunel’s famous railway bridge. The Maidenhead bank is lined with large Edwardian houses. The Thames Path follows the Bucks (Eastern) bank to Maidenhead Bridge, which it crosses, and then proceeds on the Berkshire side to Boulter’s Lock.

Airport luggage locks || Power door locks

Posted on December 17th, 2007 in Uncategorized by admin

Power door locks (aka electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.

Power door locks were introduced on the luxury Scripps-Booth in 1914, but were not common on luxury cars until Packard reintroduced them in 1956. Nearly every car model today offers this feature as at least optional equipment.

Early systems locked and unlocked only the car doors. Many cars today also feature systems which can unlock such things as the luggage compartment or fuel filler cap door.

It is also common on modern cars for the locks to activate automatically when the car is put into gear or reaches a certain speed. Automatic unlocking when the car is parked is usually also featured on such systems.

Remote and handsfree

Today, many cars with power door locks also have a remote keyless system, which allows a person to press a button on a remote control (or, on some Ford cars and trucks, enter a combination on an external keypad) to unlock the car without using a key. This system confirms successful (un-)locking through either a light or a horn signal, and usually offers an option to switch easily between these two variants. Both provide almost the same functionality, though light signals are more discreet while horn signals might create a nuisance in residential neighborhoods and other busy parking areas (e.g. short-term parking lots).

Other cars have a proximity system that is triggered if a keylike transducer (Advanced Key or handsfree) is within a certain distance of the car.

Finally, some other includes garage door opener, integrated.

Travel sentry certified luggage lock || Buck knife

Posted on December 17th, 2007 in Uncategorized by admin

A buck knife (or buck-knife) is a kind of folding lock-blade knife, meaning a knife whose blade folds into its handle, as with a common pocket knife, but locks into place when opened, so that it cannot close unless the release is pressed.

The term is a genericization of Buck Knife. “Buck Knives” is a leading American maker of knives of many sorts, but it is especially noteworthy for producing the first really successful folding lock-blade, introduced in 1964.http://www.popularmechanics.com/outdoors/adventures/1277451.html Folding lock-blade knives and “Buck Knife” thereby became strongly linked in the public mind, and the Buck design was much imitated, so that a buck knife, in common understanding, has come to mean any folding lock-blade of like design, even while Buck Knife is yet a trademark and not limited to folding lock-blades.http://www.aepma.org/list/trademark.asp

Suitcases luggage || Marianne Sägebrecht

Posted on December 11th, 2007 in Uncategorized by admin

Marianne Sägebrecht (born August 27, 1945) is a German actress, most famous for her appearance in the movies Sugarbaby, Out of Rosenheim (Bagdad Café) and The War of the Roses.

She was born in Starnberg, Bavaria.

This Rubanesque character player with a heart-shaped face and child-like features began her career as a leading producer and performer of Germany’s alternative theater/cabaret scene. The eclectic background of Marianne Sagebrecht included stints as a medical lab assistant and magazine assistant editor before she found her calling in show business. Claiming to be inspired by Bavaria’s mad King Ludwig II, she became known as the “mother of Munich’s sub-culture” as producer and performer of avant-garde theater and cabaret revues, particularly with her troupe Opera Curiosa. Spotted by director Percy Adlon in a 1977 production of “Adele Spitzeder” in which she essayed the role of a delicate prostitute, Sagebrecht was cast as Madame Sanchez/Mrs. Sancho Panza in Adlon’s TV special “Herr Kischott” (1979), a spin on “Don Quixote”. The director put her in his 1983 feature “The Swing” in a small role and then created the leading role of Marianne, an overweight mortician in love with a subway conductor, in “Sugarbaby” (1985) especially for her.

American films beckoned as well and Sagebrecht was often cast in roles tailored to her unique abilities. Paul Mazursky reworked the part of a Teutonic masseuse for her in “Moon Over Parador” (1988) while Danny De Vito tailored the part of the German housekeeper for a divorcing couple in “The War of the Roses” (1989). Returning to Germany, she shone as the timid maid in the 1930s who marries her Jewish employer for convenience then falls in love in “Martha and I” (1990; released in the USA in 1995). Sagebrecht headlined the black comedy as an unhappy wife whose straying husband plots her death in “Mona Must Die” (1994) and had small supporting parts in “The Ogre” (1996) and “Lost Luggage” (1998).

Safe skies luggage locks || Bingley Five Rise Locks

Posted on December 5th, 2007 in Uncategorized by admin

Bingley Five Rise Locks is a staircase lock on the Leeds and Liverpool Canal at Bingley (). As the name implies, a boat going up the lock is lifted in five stages.

Description

In effect the 5-rise consists of five locks connected together with (as always with a staircase) no intermediate “pounds”: the lower gate of each chamber forms the upper gate of the chamber below. There are therefore five chambers, and six gates (the top and bottom gates and four intermediate gates). As the Leeds Liverpool canal is a wide canal, the chambers are 14 feet wide, and each “gate” consists of two half-gates, “hinged” from opposite sides of the canal. Each half gate is slightly more than 7 feet wide, so that the two halves close in a “V” shape (pointing “upstream”). Water pressure on the “uphill” side of the gate thus keeps it tightly closed until the water levels on either side are equal, when the gate can be opened and the boat moved to the next chamber (see canal locks for more information on how a lock is constructed and operated).

The 5-rise is the steepest flight of lock in the UK, with a gradient of about 1:5 (a rise of 59ft 2in over a distance of 320ft). The intermediate and bottom gates are the tallest in the country. Because of the complications of working a staircase lock, and because so many boaters (both first-time hirers and new owners) are inexperienced, a full-time lock keeper is employed, and the locks are padlocked “out of hours”. Barry Whitelock, the “locky”, after twenty years based here is now almost infamous on the local canals. Barry was awarded an MBE (Member of the Order of the British Empire) in the 2006 New Year Honours List for “Services to Inland Waterways in the North”

History

It opened on March 21 1774 and was a major feat of engineering at the time. When the locks and therefore the canal from Gargrave to Leeds was opened in 1774 a crowd of 30,000 people turned out to celebrate it! The first boat to use the locks took just 28 minutes and the whole first trip is described here as it was in a newspaper of the time - the Leeds Intelligencer. The smaller Three Rise opened at the same time just a few hundred meters further down.

During 2000-2004, famous Leeds Chartered Surveyor, Gerwyn Bryan, lived in the famous cottage looking down on the locks, which appears in many pictures of the locks.

Tourism

The “flight” (it is a moot point whether a staircase is strictly a “flight”, used strictly the term means a group of locks separated by intermediate pounds, so each lock has its own top and bottom gates) is a major tourist attraction in the area. Most boats that pass through attract a lot of attention especially at weekends where they may be a crowd of thirty people or more watching a boat go up or down!

Maintenance

The staircase underwent extensive restorative maintenance in 2004,and again in 2006 when the lock gates and paddles were replaced. As is expected with such a feat of engineering it requires a lot of maintenance and is often on British Waterway’s list of winter stoppages for maintenance.

Tsa locks on luggage || Record locking

Posted on December 4th, 2007 in Uncategorized by admin

Record locking is the technique of preventing simultaneous access to data in a database, to prevent inconsistent results.

The classic example is demonstrated by two bank clerks attempting to update the same bank account for two different transactions. Clerk 1 and clerk 2 both retrieve (ie, copy) the account’s current balance. Clerk 1 applies one transaction and refiles the new balance. Clerk 2 applies a different transaction and refiles a new balance that obliterates the information saved by clerk 1. The resulting account balance no longer reflects the first transaction.

To prevent inconsistencies created by that kind of unlimited access, the account’s record can instead be immediately locked upon being retrieved for any subsequent update. Anyone attempting to retrieve the same record for editing is denied access because of the lock (although, depending on the implementation, they may be able to view the record without editing it). Once the record is saved or edits are canceled, the lock is released, thereby always insuring consistent data within the record being edited.

Use of locks

Record locks (hereafter lock(s)) need to be managed between the entities requesting the records such that no entity is given too much service via successive grants, and no other entity is effectively locked out. Care should also be used to avoid a deadlock condition which can bring the application or system to a halt. The entities that request a lock can be either individual applications (programs) or an entire processor.

The application or system should be designed such that any lock is held for the shortest amount of time possible. Given that there may be considerable overhead to the process of requesting, and subsequent granting of a lock, it may make sense to investigate if an entity can forego a lock if the purpose is simply to read non-critical data.

There are two main types of locks that can be requested:

Exclusive locks

Exclusive locks are as the name implies, exclusively held by a single entity. If the locking schema was represented by a list, the holder list would contain only one entry. Since this type of lock effectively blocks any other entity that requires the lock from processing, care must be used to:

  • Ensure the lock is held for the least amount of time possible
  • Do not hold the lock across system/function calls where the entity is no longer running on the processor - this can lead to deadlock
  • Ensure that if the entity is unexpectedly exited for any reason, the lock is freed otherwise deadlock will likely occur.

Non-holders of the lock (aka waiters) should perhaps be maintained in a list that is serviced in a round robin fashion. This would ensure that any possible waiter would get equal chance to obtain the lock and not be locked out. To further speed up the process, if an entity has gone to sleep waiting for a lock, performance is improved if the entity is notified of the grant, instead of discovering it on some sort of system timeout driven wakeup.
