The AA-12 (Auto Assault - 12), originally designed and known as the Atchisson Assault Shotgun, is a fully automatic combat shotgun developed in 1972 by Maxwell Atchisson. . However, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately led to the gun entering the market being done later by Military Police Systems ...
Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
Telescopic cylinders must only be used in machinery as a device for providing force and travel. Side forces and moment loads must be minimized. Telescopic cylinders should not be used to stabilize a structural component. [4] Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi.
Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types. Open center circuits use pumps that supply a continuous flow.
A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
The 12/70 gun is a fully automatic, water-cooled vertical sliding wedge design mounted in an armored turret which is electrically traversed under computer control while the elevation motor is controlled manually (presumably a cost-cutting measure). It is fed from a magazine several meters below ground where the crew uses special air-cushion ...
