Title: Safety controls for tailgate hoist - include twin switches allowing two handed operation only
Inventor: SITTER WILLI
IPC: B60P1/44
Filed: 1978-06-01
Abstract: The hydraulically operated tailgate hoist has two hydraulic servos to tilt the tailgate between the vertical and horizontal positions and two rams to raise and lower the gate. The servos and rams are controlled by twin switches to ensure that the operator cannot trap his hands, or feet in the mechanism. The failsafe connections for the servo operating relays ensure that if one switch is released the other has to be released before the two switches can be activated again. This prevents jamming of any one switch allowing dangerous one handed control.

Title: Hollow charge in projectile has booster in two possible positions - one for striking target other if target missed
Inventor: PETTERS WILLI DR ING DR
IPC: F42C19/08
Filed: 1978-12-29
Abstract: A hollow charge projectile, typically for dropping by parachute, and esp. having positioning elements which can be folded down from the outer face of the casing, contains a firing system which detonates either by direct impact on the target or if the target is missed. A double hollow charge between two hollow charge inlays at opposite ends of the casing contains, centrally, a cylindrical chamber containing a booster and connecting the two inlays together. This booster is fixed in a first (upper) position (A) by means of an attachment of limited strength so that when this attachment intentionally ruptures on impact the booster moves to a second position (B) at the opposite end of the cylindrical chamber. If the charge, when dropped, falls directly onto its target the booster operates in position (A), whereas if the charge misses the target and lands upon the ground the booster becomes detached from this position and falls to position (B), where the explosion is directed upwards.

Title: Turbine power block control system - changes constant pressure boiler operation to variable pressure on sudden frequency deviation
Inventor: RENZE HEINRICH ING GRAD
IPC: F01K13/02
Filed: 1979-01-31
Abstract: Protective control of a steam generator in a power block is ensured by minimising fluctuations of its regime by meeting demands through setting of the turbine valve. The accumulated steam of the boiler is drawn only in the case of sudden deviation from the nominal value of the frequency of the generator. The error signal derived from frequency variations is used for driving the servo of turbine valve to alter the flow cross-section in order to stabilise the power block frequency. Delay in the response is controlled when a change from filtered pressure to variable pressure is taking place. A rctifier blocks positive going signals to maximum selector circuit in the supply of the servor. The circuit includes a high pass filter and a delay element, connected to a subtraction unit.
