Title: Anti jack-knife control for vehicle - has sensor arm to monitor rate of angular displacement relative to travel axis and control locking of towing coupling
Inventor: REINECKE ERICH
IPC: B62D53/04
Filed: 1978-03-13
Abstract: The anti-jacknife control has a sprung monitor arm (12) which holds a trailing wheel onto the road with the arm linked to a reaction control to monitor the lateral forces on the arm.

Title: Forced draught burner with automatic air-fuel ratio control - has air throttle held in bimetallic disc to keep mass flow constant
Inventor: BRUNS GERD
IPC: F23D11/00
Filed: 1979-04-12

Title: Temporary temp. limiter for thermostat-controlled radiator - has timing switch controlling thermostat electric heating for reduced temp. in rooms not in use
Inventor: PELZER HEINZ DR
IPC: G05D23/32
Filed: 1979-05-03
Abstract: The limiter is intended for heating energy reduction by lowering the temp. in rooms which are not in use. The temp. reduction is carried out automatically without excessive cost and by maintaining limited spatial demands for the arrangement, which is applicable to individual thermostats controlling hot water or steam heating systems. Each thermostat valve is electrically heated under control of a timing switch, while maintaining fully the advance heating temp. On the front face of the thermostat valve of a room radiator is secured an electric resistor, covered by a thin thermal insulating disc. The resistor is supplied with an alternating voltage of 24 V during off-peak period under control of a timing switch. 15 minutes after switching-on the hot water supply stops and is resumed after a temp. drop of 5 deg. K.

Title: Flat roof leakage detecting system - has electric conductor arrangement between flat support and seal for resistance change scanning
Inventor: LUBER WILLIBALD
IPC: E04B1/66
Filed: 1979-05-25
Abstract: The detection system is intended for flat roofs, bridge decks etc. and comprises an arrangement of electrical conductors between the substrate, such as concrete, and the sealing overlay, e.g. a water-proof membrane. When water leaks through the seal, the electric resistance of the conductors changes. Alternately the water may connect mutually isolated conductors causing a short circuit between them so that, when the isolation resistance is measured by passing a current pulse, its value is less than under normal conditions. Both methods may be employed together and the results indicated by both compared to increase the reliability with which leaks are detected. The arrangement of conductors may be broken down into subarrangements to facilitate localising the leak.

Title: Vehicle position transmitter supply - has induction coil to generate transient field when road wheel passes over fluid filled tube
Inventor: RUBEL ERICH DIPL ING
IPC: G05D1/02
Filed: 1979-08-02
Abstract: The transmitter coupled to a detector that is triggered by the passage of a road vehicle, operates without an external electrical supply. The passage of a vehicle is detected by the road wheels compressing a tube (1) filled with hydraulic fluid to cause bellows (5) to expand. The bellows operates a lever (6) to cause the yoke of an electro magnet to leave the permanent magnets (7,8) and so cause transient field in an inductive coil (9). The signal is rectified (11) and causes a high frequency signal to be transmitted (14) over an aerial (15).

Title: Self braking palette trolley - has overrun brakes operated by drawbar and with central frame to mount drawbar and rear coupling
Inventor: FREY WILLI ING GRAD
IPC: B60T7/20
Filed: 1979-08-13
Abstract: The self braking pallet trolley has a low support platform on a simple chassis of a central frame member (2). A rear coupling (4) on the frame enables a following trolley to be attached while the trolley moves relative to the frame during braking. The brakes are linked to the displacement of the frame to act as overun brakes. When several trolleys are linked into a train the force is taken through the central frames. The drawbars are hinged at the front of each frame, and linked to the steered front wheels by steering rods. The amount of braking force on each trolley is dependent on its loading, to relieve the towing vehicle of the greater part of the braking effort.

Title: Test gauge for holes drilled through coal seam - uses inserted tube to measure longitudinal and cross-sectional alterations caused by roof pressure
Inventor: BRAEUNER GERHARD DR
IPC: E21B47/00
Filed: 1979-10-16
