It acts directly on the levers and interconnecting rods that operate the door, completely avoiding the complexity of dealing with the lock mechanism itself. The hooked end of the tool is slipped between a car's window and the rubber seal, catching the rods that connect to the lock mechanism. With careful manipulation, the door can be opened. [1]
Pressing a button on the key unlocks all of the car doors. Another button locks the car. In 1980, Ford Motor Company introduced an external keypad-type keyless entry system, wherein the driver entered a numeric combination —either pre-programmed at the factory or one programmed by the owner— to unlock the car without the key.
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
They can be used on very thin sheet metal, but metals tend to cause premature bit wear and dulling. Unibits are ideal for use in electrical work where thin steel, aluminum or plastic boxes and chassis are encountered. The short length of the unibit and ability to vary the diameter of the finished hole is an advantage in chassis or front panel work.
Locks have been constructed for over 2500 years, initially out of wood and later out of metal. [1] Historically, locksmiths would make the entire lock, working for hours hand cutting screws and doing much file-work. Lock designs became significantly more complicated in the 18th century, and locksmiths often specialized in repairing or designing ...
Until 2004, Kryptonite locks used the tubular pin tumbler locking mechanism. In 2005, after it was demonstrated that the tubular pin tumbler locks used on Kryptonite locks could easily be opened with the shaft of a Bic ballpoint pen of matching diameter, [9] Kryptonite changed their locks from the tubular to a disc mechanism, preventing the use of cylindrically shaped objects to defeat the ...
The back plate has various shapes: Full plate movement In this design, used in the earliest pocketwatches until the 18th century, the back plate was also circular. All the parts of the watch were mounted between the two plates except the balance wheel, which was mounted on the outside of the back plate, held by a bracket called the balance cock.
A hand-held tungsten carbide knife sharpener, with a finger guard, can be used for sharpening plain and serrated edges on pocket knives and multi-tools.. Sharpening is the process of creating or refining a blade, the edge joining two non-coplanar faces into a converging apex, thereby creating an edge of appropriate shape on a tool or implement designed for cutting.
