In May 2005, the U.S. Armed Forces began replacing the standard Small Arms Protective Insert plates with the Enhanced Small Arms Protective Insert (ESAPI). [ 1 ] [ 2 ] An ESAPI provides protection from .30-06 Springfield M2 armor-piercing (AP) with a steel [ 3 ] [ 4 ] penetrator in accordance with the NIJ Level IV standard, but costs about $600 ...
A ballistic plate, also known as an armour plate, is a protective armoured plate inserted into a carrier or bulletproof vest, that can be used stand-alone, or in conjunction with other armour. "Hard armour" usually denotes armour that uses ballistic plates. It serves to defeat higher threats, and may be considered as a form of applique armour.
Over 120,000 inserts were procured; [24] however, the AP threats they were meant to stop never materialized, and the plates were put into storage. XSAPI plates have a tan fabric cover with black text. Early plates have the text "7.62 mm AP/WC Protection" [25] inscribed on the back; on newer variants, this text instead reads "XSAPI - REV. B" or ...
The strike plate protects the jamb against friction from the bolt and increases security in the case of a jamb made of a softer material (such as wood) than the strike plate. Some strike plates have their hole size and placement calculated so a spring-bolt extends into the hole, but an adjacent anti-retraction device remains depressed ...
The size is imprinted on the spanners in millimeter values or inch sizes with intermediate sizes in fractions (older British and current US spanners). The two systems are in general not compatible, which can result in rounding of nuts and bolts (i.e. using a 13 mm (0.51 in) spanner in place of a 1 ⁄ 2 inch (12.70 mm)).
The plates were expendable, so it was not unusual as shown in both photos for a machinist to drill additional holes in the plates for attaching work that could not otherwise be attached. While the dog plates were usually fairly small regardless of the lathe size, the classic face plate is usually matched to the maximum diameter that the lathe ...
Faceplate (face plate, face-plate) is a plate, cover, or bezel on the front of a device, such as: Computers and electronics.
The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.
