Tumi luggage lock || Shear line (locksmithing)

Posted on March 31st, 2008 in Uncategorized by admin

In lock picking a cylinder lock, the shear line, also known as the split line in Australia, is where the inner cylinder ends and the outer cylinder begins. When a correct change key or master key is inserted in the cylinder, it will align the pin segments with the shearline and allow the cylinder to be turned. This break in the lock mechanism is a vital part of the lockpicking process, as it allows a picked pin to “hang” while the others are being picked.

Luggage lock instructions || SR Class CW

Posted on March 30th, 2008 in Uncategorized by admin

The Southern Railway (SR) gave the designation CW to the fleet of AC electric multiple units used on the lines to Coulsdon and Wallington. They were planned by the London, Brighton and South Coast Railway but were delayed by the Grouping and were introduced by the Southern Railway.

Construction

The CW (Coulsdon and Wallington stock) units were built in 1923-1924, as the last electric train stock for use on the LBSCR AC overhead electrified lines in South London. This stock comprised some hundred carriages, which were used in five car formations (Driving Trailer Third + Driving Trailer Composite + Motor Luggage Van + Trailer Composite + Driving Trailer Third).

The stock, built by the Metropolitan Carriage Wagon & Finance Company at Birmingham, was as follows:

  • 21 Motor Luggage Vans
  • 60 Driving Trailers
  • 20 Trailers

The Motor Luggage Vans (nicknamed “Milk Vans”) each had four 250 horsepower GEC traction motors.

After the replacement of the AC overhead equipment by the 660 V DC third rail system adopted as standard by the SR, the carriages that formed these units were rebuilt accordingly, the Motor Luggage Vans becoming goods train guard’s vans.

Travel sentry || Metropolitan Travel Survey Archive

Posted on March 30th, 2008 in Uncategorized by admin

The Metropolitan Travel Survey Archive is a project to store, preserve, and make publicly available, via the internet, travel surveys conducted by metropolitan areas, states and localities.

To date the project has collected over 50 surveys from 28 metropolitan areas which can be downloaded by users.

The motivation behind the archive is to forestall the loss of electronic files and documentation of surveys, which has befallen previous surveys. These surveys are both costly to conduct, and irreplaceable as it is impossible to reconstruct past records of human travel behavior.

Luggage locks and tags || Windsor Locks, Connecticut Tornado

Posted on March 30th, 2008 in Uncategorized by admin

The Windsor Locks, Connecticut tornado struck on October 3 1979. The short-lived, but intense F4 tornado (see Fujita scale) caused 3 deaths, 500 injuries, and - with more than $300 million in property damage along an 11-mile path - ranks as one of the most expensively destructive tornadoes in American history.

The tornado touched down in the town of Poquonock, Connecticut, just north of Hartford, Connecticut in the Connecticut River valley. It traveled north through the town of Windsor Locks, Connecticut before dissipating in the town of Suffield, Connecticut, just south of the Massachusetts state line.

The path of the tornado crossed the northern portion of Bradley International Airport, and many vintage aircraft at the nearby New England Air Museum were damaged or destroyed by the storm.

Master luggage locks || Deadbolt

Posted on March 30th, 2008 in Uncategorized by admin

A deadbolt is a special kind of locking mechanism, providing more security than an ordinary key-operated lock because the weight of the locking bar is usually sufficient to increase break-in time to 10 or 15 minutes.

Unlike most spring-bolt locks, in which the bolt is held in place only by the pressure of a spring and can easily be retracted, a deadbolt lock cannot be opened except by rotating the lock cylinder.

A variant of the standard deadbolt is the vertical deadbolt, which generally rests on top of a door. Vertical deadbolts resist jimmying (in which an intruder inserts a pry bar between the door and the frame and tries to pry the bolt out of the jamb).

Security Features

Many designs are available from manufacturers. Various manufacturers have patented designs offering unique solutions to prevent the locks from being defeated by picking, lock bumping prying, and other forceful attacks.

Locked luggage || Test and Test-and-set

Posted on March 29th, 2008 in Uncategorized by admin

In computer science, the test-and-set CPU instruction is used to implement
mutual exclusion in multiprocessor environments. Although a correct lock can be implemented with test-and-set, it can lead to memory contention in busy lock (caused by bus locking and cache invalidation when test-and-set operation needs to access memory atomically).

To lower the overhead a more elaborate locking protocol test and test-and-set
is used. The main idea is not to spin in test-and-set but increase the likelihood of successful test-and-set by using following entry protocol to the lock:

boolean locked := false // shared lock variable
procedure EnterCritical() {
  do {
    while (locked == true) skip // spin until lock seems free
  } while TestAndSet(locked) // actual atomic locking
}

Exit protocol is:

procedure ExitCritical() {
  locked := false
}

The entry protocol uses normal memory reads to spin, waiting for the lock to become free. Test-and-set is only used to try to get the lock when normal memory read says its free. Thus the expensive atomic memory operations happens less often than in simple spin around test-and-set.

If the programming language used supports minimal evaluation, the entry protocol could be implemented as:

 procedure EnterCritical() {
   while ( locked == true or TestAndSet(locked) == true )
     skip // spin until locked
 }

Caveat

Although this optimization is useful in system programming it should be avoided in high level concurrent programming. One example of bad usage of this idiom is double-checked locking, which is listed as an anti-pattern.

Tsa approved luggage lock || Caversham Lock

Posted on March 29th, 2008 in Uncategorized by admin

Caversham Lock is a lock and weir situated on the River Thames in Reading, Berkshire, England. Caversham Lock includes a somewhat larger than normal lock island, also known as De Bohun Island, separating the lock from the weir.

The lock, weir and island is owned and managed by the Environment Agency. Besides a typical lock-keeper’s house, the island until recently contained a boat yard and boat house used by the Environment Agency’s river patrol and maintenance services. At the time of writing (December 1, 2004), controversial proposals to redevelop the island and some adjoining land as a hotel are under discussion.

Access to and across the lock

A public access exists across the lock gates, lock island and weir, forming a pedestrian route from the centre of Reading to the Lower Caversham area of the cross-river suburb of Caversham.

Reach above the lock

The river passes though the built up area of Reading under Reading Bridge and Caversham Bridge. The north bank passes through the suburb of Caversham before reaching open meadows, while on the south bank is Tilehurst and later Purley-on-Thames. The Thames Path follows the south bank to Mapledurham lock.

Victorinox luggage || Left Luggage (film)

Posted on March 29th, 2008 in Uncategorized by admin

Left Luggage is a 1998 film directed by Jeroen Krabbé.

Plot

While escaping from Nazis during WWII, a Jewish man buried two suitcases full of things dear to his heart in the ground. The war deprived him of his family, and afterwards he endlessly turns over the soil of Antwerp to find the suitcases, an obsessive compulsion. He keeps checking old maps and keeps digging, trying to find what he lost. His daughter Chaya is a beautiful modern girl looking for a part-time job. She finds a place as a nanny in the strictly observant Chassidic family with many children, although her secular manners clearly fly in the face of their beliefs. One of the reasons she is accepted is that mother of the family is absolutely overburdened by the household, so she stays despite the resistance of the father, normally, an indisputable authority in the family. She develops a special bond with the youngest of the boys, four-year old Simcha, so far incapable of speaking. She encourages him to speak while walking in the park, and it seems that during the upcoming Passover Seder, Simcha will be able to chant the section of the Haggadah usually reserved for the youngest speaking participant - the Ma Nishtana. However, Simcha’s nerves prevent him from singing, and his brothers sing instead. The superintendent of the building is a constant wet blanket for the entire family and now for Chaya. However, as opposed to the observant Jews, she cannot be a victim and is not going to put up with his anti-Semitic tricks, so she fights him, thus exciting the children’s admiration and father’s wrath.

Unfortunately, walks with Simcha end in a tragedy: after sneaking to the park, he drowns in the pond, chasing the ducks he loved so much. Some in the community hold Chaya responsible for his death. However, in a scene where Chaya goes to the family’s mourning service, the mother feels compassion for Chaya and realises that Chaya felt a deep connection with Simcha. As an act of acceptance, the mother - played by Isabella Rossellini - rips Chaya’s shirt, which is a sign of a mourner (a sibling, parent, child or spouse of the deceased) in Jewish tradition.
