Title: Security lock and theft alarm for motor vehicle - has electronic transmitter and receiver linked by non-electrical circuit
Inventor: FOERSCHNER ALFRED
IPC: B60R25/24
Filed: 1979-06-29
Abstract: The circuit gives high security vehicle lock which cannot be defeated through bypassing electrical circuits. The security system comprises a transmitter, and a receiver linked with that part of the vehicle chosen to effect the immobilisation. The link between transmitter and receiver is non-electrical. The receiver and associated locks are contained in an armoured box. Typically the transmitter generates an eight digit code word in which each digit has sixty four possibilities. The word is transmitted serially, for example as modulated light pulses along a light guide. The receiver checks the incoming word for validity and then acts upon the instruction. The electrical circuit of transmitter and receiver are separate. Action upon a correct word arriving at the receiver may be time delayed to prolong the time required for any attempt to defeat the system by trial and error. The system would normally also incorporate an audible or visible alarm to give warning if the vehicle is tampered with.

Patent DE-2931137-A1 (DE)
Inventor: BUCHER HEINZ
IPC: A61H33/02
Filed: 1979-08-01
Abstract: The bubble grid has two separate distribution systems (MT1, MT2) having outlet orifices (AÖ1, AÖ2) for the supplied bubbling medium, air (DL) and/or water. Exposure of the two distribution systems (MT1, MT2) to the bubbling medium is not selective but periodic (f) and with temporal phase offset. For this purpose, the feed line includes a switch-over device (U) which supplies the constant inflow of the bubble grid as pulsed flows with different phase positions to the two distribution systems (MT1, MT2). These pulsed flows add up to the constant inflow. The supplied bubbling medium is therefore fully utilised despite the pulsed bubbling, and the two distribution systems (MT1, MT2) which are controlled in a temporally offset manner improve the massaging effect. <IMAGE>

Patent DE-3017622-A1 (DE)
Title: Sewage sludge digestion tank heating system - controlled by adjusting hot water circuit through heat exchanger
IPC: C02F3/00
Filed: 1980-05-08
Abstract: Heating system for digestion tanks transfers heat from a hot water circuit with a heating boiler to the circulating sewage sludge in a heat exchanger. When the sludge absorbs more heat, the drop in the returning hot water temperature to a lower critical value is compensated by reducing its flow rate through the heat exchanger by a bypass. When the return temperature rises above an upper critical temperature, the hot water flow rate is adjusted to maintain the desired temperature of the circulating sludge. This is a reliable way of preventing the hot water temperatures from dropping below the critical figure of 65 deg.C and of eliminating any thermal shocks in the digestion tank when fresh sludge is charged.

Patent DE-3100224-A1 (DE)
Title: Collision warning system for motor vehicles, having a particularly low false alarm rate
Inventor: RUPPEL WERNER DR
IPC: G01S13/931
Filed: 1981-01-07
Abstract: Collision warning systems which consist of a directional antenna which radiates linearly polarised signals and receives echo signals polarised orthogonally thereto, of a pulsed radar operating with stochastic pulsing at high duty ratio and of signalling devices, and which warn optically, acoustically and kinetically with each threatening collision, only rarely produce a false alarm due to their high noise immunity. However, so that even the remaining false alarms are eliminated as completely as possible, the reflection characteristic of the traffic objects is improved by equipping them with passive polarisation-rotating reflectors in such a manner that the echo signals of non-traffic objects fall below the receiving threshold. As the false alarm rate disappears, all impact accidents threatening due to inattentiveness of the driver are automatically avoided by reduction of the driving force with each alarm and by appropriate additionally triggered braking measures in the case of an intensive alarm.
