Title: Multi-layered flat roof membrane - with weatherproof-layered track on inset-reinforced track with intervening air layer
Inventor: JUNGBLUT HEINZ
IPC: E04D13/17
Filed: 1974-05-24
Abstract: The composite roof skin, esp. for use on flat roofs incorporates a length which is reinforced by an insert carrier, and on top of which is applied a length coated with bitumen or other weatherproof material, leaving an layer or air which is formed round punctiform or slit-shaped connecting points. The interfacing sides of the two tracks may be coated with an insulating layer. The top of the bottom track may be coated with metal or plastic foil, and the bottom of the upper one with similar material, or with woven glass. The two tracks may be mutually offset to provide an overlap edge, for welding or cementing. Damage and separation resulting from seasonal temperature and other weather variations are prevented.
Patent DE-2425304-A1 (DE)
Title: Alcohol breath test for driver - has pull out hose to inflate crystal containing balloon below dashboard
Inventor: DIETZ ALBERT
IPC: B60R25/04
Filed: 1974-05-25
Abstract: The dashboard is fitted with a pull-out rubber hose with mouthpiece into which the driver blows before he can start the car. The hose inflates a balloon inside a metal container with a microswitch at the end. This ensures that the balloon has to be fully inflated to close the microswitch and operate the first interlock. A light sensing semiconductor monitors the colour change, if any, on alcohol detecting crystals in a replaceable tube in the mouth of the balloon. If the test is negative, then the circuit is open for starting, and remains open for a set time interval, e.g., five minutes, to cover any difficult starting. After this time interval the test has to be repeated every time the car stops.

Title: Caliperless fully lined disc brake - has disc-shaped friction plate axially movable and brake pads arranged of both sides of plate
Inventor: BARONNET PIERRE
IPC: F16D55/00
Filed: 1974-06-06
Abstract: A friction plate is keyed on the hub of the rotating wheel (22) but with a limited possibility of axial movement. By providing a number of friction pads 2, 3 acting on both sides of the friction plate simultaneously the braking effect is considerably increased and due to lower operating temperatures the life of the pads is prolonged. The arrangement is most suitable for heavy duty applications, such as buses. The disc nearest the hub have cooling apertures, which ensure that pressurised air from a cylinder flows alongside the discs and between the adjacent brake disc components.

The articulated chain joints provide a simple but reliable locking mechanism for the back rest section so that the latter can be at various stepped positions, wherein the edge (9) of the back rest (4) facing the centre section (2) is supported against graduated stops (7, 8).
Patent DE-2512889-A1 (DE)
Title: Tubular inductive element with airgap - is manufactured by focussing laser beam on axially moving outer surface for elongated holes
Inventor: WHITLEY THOMAS JOSEPH
IPC: B23K26/06
Filed: 1975-03-24
Abstract: Tubular inductive component is manufactured with an airgap to produce a high magnetic reluctance. The material is a hard, brittle ceramic which has magnetic properties, and a conductor is fed through the hollow of the tube. A laser beam is concentrated on the outer surface of the tube to cause part of the material to evaporate. The tube is then moved in the axial direction relative to the beam which produces a longitudinal slot in the outer surface of the material. The guide slab has a V shaped channel for sealing the workpiece. The size and shape of the elongated holes can be controlled. The focussing of the beam is such that the material structure of the remote wall will remain unaffected.

Title: Sports boot with profilated sole - has recessed surface supporting grid of decreasing height with cushioning layer inside boot
IPC: A43B5/10
Filed: 1975-06-09
Abstract: The body of the profilated sole is bowl-shaped with an upwards pointing rim (2) along the entire circumference.

Title: Ships sewage treatment plant - using flocculants, electrolytic reactor, settling basins and sludge incinerator
Inventor: KRUGMANN HANS-GUENTHER
IPC: C02F9/00
Filed: 1975-09-29
Abstract: The sewage is passed, after the admixture of flocculants, through a shredding pump and into a settling basin. An electrolytic treatment in the following reactor uses the oxygen and hydrogen released to oxidise organic matter and kill all bacteria. The solids are deposited in a final settling tank. The sludge is incinerated and the clarified water is discharged overboard. This requires no bacterial cultures for biochemical treatment which may be detrimentally affected in the tropics. The system eliminates organic waste as well as kills all germs and is instantly ready for use, with a high functional reliability.
