Patent GB-2046385-A (GB)
Title: Anti-skid system
IPC: B60T8/34
Filed: 1980-03-19
Abstract: A differential pressure limiting valve (7) is provided between two brake cylinders (8, 8'), preferably between two brake cylinders on one vehicle axle, in an anti-skid system. The differential pressure limiting valve (7, 20, 21) comprises two relief valves (9, 10), each of which is fitted in a cross-connection line (11, 12) leading to the other brake cylinder (8, 8'). Greatly differing brake pressures are equalised by means of the differential pressure limiting valve (7), thus to prevent moments about the vertical axis of the vehicle and so reduce the risk of the vehicle going into a spin, especially in the case of short wheel base vehicles. <IMAGE>

Patent GB-2114719-A (GB)
Title: Assessment of weapon fire control systems
Inventor: JAMES DAVID ROBINSON
IPC: F41G3/32
Filed: 1982-02-12
Abstract: Fire control systems which control the firing of weapons, such as guns, are becoming more complex in order to enable a target to be rapidly engaged and to achieve a sufficiently high probability of producing a target strike with the first shot which is fired. Fire control systems commonly include a predictor which measures the position, range and direction of a target at a particular instant, and predicts where the target will be a period of time later (which corresponds to the flight time of a shell). Thus, if the predictor works correctly a direct hit will be achieved by the shell. In order to enable the performance of a predictor to be assessed without the need to repeatedly fire shells at a real target, the actual position of the target is measured at a particular instant, and the boresight direction of the gun at a previously instant in time is also measured to allow for the flight time. Using this information it is determined whether a shell launched at the previous instant in time would, in fact, have struck the target. By this means the performance of a predictor can be thoroughly assessed without the need to engage a real target or to fire live ammunition.
