Title: Protection of cables in hazardous environments - uses fail safe electronic circuitry fed with impulse control signals
Inventor: BEERMANN DIETER DIPL PHYS DR
IPC: H02H7/22
Filed: 1975-03-13
Abstract: A cable feeding al lamp is supplied from a power source and in series is a solid state switch, typically a switching transistor, fed with impulses from a pulse generator via a logic unit which cause periodic momentary short circuits. If the transistor fails the condition is recognised by differentiator and integrator circuits and a safety switch is opened. If there is a fault in the cable the potential distribution is disturbed and a detector output to the logic circuit causes the solid state switch to short circuit the supply and thus trip the safety switch. A lock-in circuit prevents automatic resetting should the fault disappear, and a back up arrangement for the detector may be provided to cater for failure.

Title: Float-actuated valve for control of water level - has immersed plate to stabilize float movement
Inventor: GOETZ HANS-DIETER
IPC: E03D1/32
Filed: 1975-03-22
Abstract: The float-actuated valve for control of water level in domestic water tanks has a stabiliser plate connected to an arm by which the float is connected to the valve. The plane is below water level and is slightly downwardly curved. In operation the stabiliser prevents or reduces frequent opening and closing of the valve as may be due to the float riding on a fluctuating water level. This difficulty occurs in water pressure-augmenting plants used in high building and leads to water hammer noises. The stabiliser is readily connected to existing valve installations.
