Title: EM safety interlock for gun on firing range - prevents loading or firing unless solenoid is energised by switch on control unit
IPC: F41A17/08
Filed: 1979-09-27
Abstract: A firearm for use on a firing range is fitted with electromechanical safety interlocks and connected via a multicore cable to a control unit. A blocking pin projects into the cartridge chamber and prevents loading unless it is withdrawn by a solenoid (32), operated by a switch on the control unit. The trigger and firing pin mechanism is locked by a slider. A second solenoid (48) withdraws the slider when the weapon is pointed towards the target and receives radiation from a source near the target. A special dummy practice cartridge has a groove cut to permit it to be loaded despite the blocking pin. It also connects in the chamber which energise the second solenoid (48) to withdraw the trigger lock. The interlocks are enclosed in a cover, locked to the weapon. Attempts to remove the cover without the key fire a demolition charge which destroys the trigger mechanism.

Title: Multistage filter press system for sewage sludge - recharging chambers cyclically between pressure thresholds
Inventor: KUEBLER HANS
IPC: C02F11/122
Filed: 1980-02-09
Abstract: Sewage sludge is dewatered in a multi-stage filter press in which a first active period of pumping the sludge with additives of CaO or Ca(OH)2 or FeCl2 is ended when an upper pressure threshold is reached. In several subsequent cycles the pump is switched off on reaching an upper threshold and is started when the pressure has dropped to a lower threshold. At least the first topping-up cycle is started with a time delay relative to the time of reaching the upper pressure threshold which lies between a typical value required in the preceding cycle for the pressure to drop from the upper to the lower threshold, and twice this value. Although the dry matter content of the filter cake may be at most 2-5% deg. than the optimum of 55%, the filtering time is reduced by 30% and more so that a 25% higher throughput is achieved.

Title: Radial piston hydraulic motor - has passages through valve piece to provide relief from fluctuating pressures
Inventor: RYZNER CLEMENS
IPC: F03C1/34
Filed: 1980-03-26
Abstract: Pistons reciprocating in radial cylinders act on the eccentric on a shaft (3). Pressurised liquid is admitted to each cylinder by a passage (4) in the motor end case (5). A valve piece (7) is keyed (8) to the shaft and has ports which control the flow of liquid to the cylinders. It is enclosed in a cover (9) on the outside of the end case. One port (6) communicates with the inlet (13) and the other port (23) communicates with the outlet. There is a passage (17) through the valve plate behind each port. Fluctuating pressures at the ports are thus transmitted to the cover without acting on the valve piece.

Title: Heat pump sequence operating control - combines two=stage starting and stopping cycle with intermittent operation of auxiliary heat source
Inventor: KRANZ HANS WERNER ING GRAD
IPC: F25B30/02
Filed: 1980-04-25
Abstract: The operating system for a heat pump, combined with an auxiliary heat source which may be oil or gas fired, uses the auxiliary heater for a given period of time, in which the heat pump is operated in two stages. During the first stage, the circulating refrigerating medium reaches a determined pressure and is then switched off. It is switched on again for another period until the pressure reaches the upper value again. The auxiliary heater is immediately switched off to allow the high pressure to be reached, and is switched on again at the end of the first time period, and switched off again at the end of the second period. After a minimum operating time of the auxiliary heat source, the heat pump is switched on against.
