Title: Covering metal tubes with thermoplastic - using inductive heating on the tube and a thermoset adhesive layer
Inventor: LANDGRAF HELMUT DIPL PHYS
IPC: B29C65/48
Filed: 1972-11-17
Abstract: A bonding layer of thermosetting resin is applied to the tube surface which is then covered with ethylene copolymer and polyethylene. The tube is heated by induction heating which, being concd. in its surface, rapidly cures the adhesive layer while leaving the inner part of the tube relatively cool. The process is mechanised by passing the covered tube through an induction coil, with the constants set to reach quick cure without decompsn. of the adhesive. The assembly is finally cooled to room temp.

Title: Safety mounting for wing mirror on motor vehicle - has spring loaded friction clutch using intermediate support
Inventor: REINHARDT HERBERT
IPC: B60R1/06
Filed: 1974-02-22
Abstract: The wing mirror housing is fitted to an intermediate support by means of a spring loaded friction clutch. The support has spherical surfaces to engage similar ones on the car mounted support so that the mirror inclination can be adjusted in two directions. The spring loaded clutch ensures that if a set force is exceeded on the wing mirror it folds back flat against the side of the car. The mirror mounting thus moves about three axes; two for adjustment, and one for safety flyback. The mirror adjustment can be manual or by remote control, with the same general mounting layout to reduce production costs.

Abstract: The cooler is built vertically and contains a series of cooling surfaces arranged vertically above each other. Each surface is a cast iron or steel radiator which allows powdered material to flow past it and is traversed by cooling water from a water supply circuit. The blocks are assembly independently and can be taken out separately for replacement or repair. The bottom of the cooler has a sloping section which causes the powder to fall to the front. One or more vertical shafts run up the front of the cooler and the powder falling into the bottom of these is carried to the outlet at the top pneumatically by air blown in at the bottom of each shaft.

Title: Conversion of diaphragm oscillation into proportional voltage - using light source and monotonic variable filter
Inventor: SCHARF GERHARD
IPC: H04R3/00
Filed: 1974-07-15
Abstract: The conversio method envisages the use of a photodetector, with the filter or light source/photodetector attached to the diaphragm. The system delivers a signal depending on the diaphragm deflection; or the system consists of a light source, mirror and photodetector, one of which is attached to the diaphragm, and the others are stationary; or the diaphragm movement is capacitively converted into proportional voltage values. One electrode of the capacitor is attached to the diaphragm while the other is stationary. The deflection of the membrane is thereby optically or electrically measured and converted into a proportional voltage of great accuracy.

Title: Cushion pad for accelerator pedal - with clip on fitting to dampen sudden accelerator movements
Inventor: GRUENAU DIETRICH
IPC: G05G1/487
Filed: 1974-07-17
Abstract: A foam rubber cushion (10) is moulded with a convex front (22) and a flat rear (12) and is clipped onto the accelerator pedal by clips (24, 26) moulded into the cushion or by clips attached to a rear plate fitted to the rear of the cushion. The effect of the cushion pad is to smooth out any sudden accelerator movements so that not only a fuel saving is achieved, but for high torque vehicles there is some measure of protection for the transmission. Releasing the accelerator is not affected by the pad. Another advantage of the pad is a better grip with wet soles.

Title: Excavator jib swivel joint - has glide shoe-type seating with pressure pocket and pliable sealing element between pocket and outside of seating
Inventor: LACHNER HANS DIPL ING
IPC: F16C32/06
Filed: 1974-07-17
Abstract: The design is concerned with excavators used on coal mine workings. For uniform distributing operation it is necessary to swivel the jib from side to side with resulting very high loadings on the jib seating and subsequent high wear. This is eliminated by using a gliding shoe-type seating fitted with a pressure pocket (8) the ring-shaped space between the pressure pocket and the outside of the seating having a pliable sealing element (10) which is nearly hydrostatically compensated. The sealing element can have circular or oval shape, the inner surface being provided with radial grooves (11) which can be arranged either as parallel circles or spirals, resulting an even pressure reduction towards the outside. The sealing element is connected with several pressure pockets (12, 13, 14) with pressures decreasing towards the outside.

Title: Shield support for coal mines - roofbar adjusts over forcibly guided roof wards curved path at shield tip
Inventor: BLUMENTHAL GUENTER
IPC: E21D23/00
Filed: 1974-09-13
Abstract: Shield support for mines consists of a floor bar (6), hinged waste shield (8) and roofbar (11) at the leading end of the shield which can pivot vertically relative to the shield. The roofbar travels a curved path towards the roof (2) as imposed by guides (13) in relation to the free or leading end of the main shield, and the roofbar can be located in any adjusted intermediate position along this path. Preferably the centre of curvature of this path remains level or above the horizontal plane through the rear axis (9) of the shield (8) in fully collapsed condition, the curve of the path such as exclude any braking effect between roofbar (11) and leading shield end. Guidance over this path derives from a groove open to the roof in the shield tip, or a groove in the roofbar open to the floor travelled by a guide on the bar or shield end.

Title: Telephone exchange coupler relays control - uses control signals for relay connection to line and column conductors
Inventor: KOERBER ULRICH DIPL ING
IPC: H04Q3/00
Filed: 1975-01-27
Abstract: The control is intended for bistable coupling relays in a telephone exchange switching matrix. The relays are controlled by control signals applied through line and column wires. One control signal connects a column wire (e.g. y1) to a voltage (+u, -u), and the other control signals makes or breaks a circuit for the relay (H) through a line wire (e.g. x1a or x1b). The supply of control signals to line wires (x1a, x1b, x2a, x2b...xja, xjb) is so protected from interferences that the circuit breaking cannot be disturbed. In case of an interference a circuit is broken instead of being closed. Preferably the applied voltage affects the relay via a decoupling rectifier (G11, G12) and a pair of line conductors. The circuit is controlled by a switch bridging the two line conductors.

Title: Water purificn., esp. de-salting or softening - with ion exchanger bed held down by elastic filling
Inventor: PFEFFERLE DIETER
IPC: B01J47/022
Filed: 1975-03-21
Abstract: In a process for purifying, and esp. for de-salting and/or softening water, in which the water flows upwards through a bed of ion exchanger material and the space allowed in the exchanger vessel for the movement of the ionic material, the water is always fed first into the exchanger bed, and only afterwards flows through the space allowing room for the movement of the ion exchanger material; this space is filled with an elastic ballast which holds down the ion exchanger bed against the pressure of the upwards flowing water. The process considerably improves the characteristics of the ion exchanger bed, preventing its densification and the formation of fissures allowing the free passage of water.
