Title: Ski safety release binding for frontal impact - has two interconnected spring loaded bars pivoting to one side to release ski boot
Inventor: KIRSCH BERNHARD
IPC: A63C9/00
Filed: 1976-04-10
Abstract: The safety binding releases the skier's boot in the case of a frontal shock. It comprises a tube (5, 6) on each side of the ski (1), lying in the longitudinal plane and able to pivot (7, 8) outwards. Inside each tube is a bar (2), sliding freely, and the tubes have an interconnecting spring (16). One end of each bar has a spherical head in a slot (11, 12) in an interconnecting spring-loaded transverse link (10, 15). The other end has a stop (3, 4) for the boot. Each stop operates on a curved cam plate (38) and turns outwards to release the boot. Pegs (39) limit the pivoting movement of each assembly.

Title: Field effect transistor with insulated gate inspection - by ion implantation of gate area and leakage current check between drain and source
Inventor: GERETH REINHARD DIPL PHYS DR
IPC: G01R31/26
Filed: 1976-05-29
Abstract: Field effect transistors with an insulated gate are inspected by bombarding the gate area with ions which produce an inversion layer in the semiconductor. The ions penetrate only where the insulating layer is not coated by gate material. Any defects in the gate can be detected by the measurement of the leakage current between drain and source. This is a simple way of detecting defective gates during the final check. Time and temperature effects are excluded. The ion implantation effects a self-curing of the FET's in certain cases.

Title: Low energy electron spectrometer for molecular analysis - uses oblique reflective electrostatic chamber and accelerator
Inventor: STOLTERFOHT NIKOLAUS DR
IPC: G01N23/227
Filed: 1976-10-26
Abstract: A low energy electron spectrometer is for use in atomic molecular, medical and aerosol analysis techniques. It is particularly for the detection of tunnel electrons. The beam of low energy electrons is partially reflected by an oblique electrostatic chamber into an accelerating chamber. The electrons from the source being analysed (1) enter the device through an aperture and travel through a decelerating lens array (2) into an oblique parallel plate (10, 11) electrostatic chamber in which a homogeneous field is established by a series of equipotential layers (12). Some of these electrons are reflected through an aperture (14) into a post accelerator (4) consisting of an array of parallel grids (15, 16, 17) and from this into an analysis chamber (5).

Title: Expansion ring for IC engine piston - has split steel ring embedded in thermally insulating plastics layer
Inventor: STUMP EUGEN
IPC: F16J1/04
Filed: 1977-03-15
Abstract: The steel ring is inserted at the top of the piston of the engine. It has slots which run in the axial direction and are cut alternately from the inner and outer faces. This gives the ring elasticity in both the radial and tangential directions and enables the ring to adjust itself to the dimensions of the piston. The ring is embedded in thermally insulating and elastic layer (b) of porous plastic, glass fibre or similar material. It occupies about 80 per cent of the available space in order to be able to take up the thermal expansion of the piston. The ring takes up the thermal expansion of the piston without allowing sufficient clearance to allow the piston to tilt.

IPC: A01M29/08
Filed: 1977-05-05
Abstract: In the bad-weather-warning device with two mirrors (52, 53), all the facets (54), located one next to the other, of a mirror together form a polygonal progression in their respective horizontal sections, the first mirror (52) being made up of the first (1), third (3) and fifth (5), and the second mirror (53) being made up of the second (2), fourth (4) and sixth (6), portions of a continuous polygonal progression (55), in which the reflection signals (1, 2, 3, 4, 5, 6) follow one another. Arranging the portions having uneven reference numbers in one mirror (52) and those with even reference numbers in the other mirror (53) generates light signals which jump from one mirror to the other, the effectiveness of the bad-weather-warning device thus being increased. <IMAGE>

Inventor: EBELING OLAVI DIPL ING
IPC: E04D13/04
Filed: 1977-06-04
Abstract: Conventional rainwater gulleys and an auxiliary rainwater gulley are provided on the receiving surface (12) of a building (1) with a flat roof structure. The auxiliary gulley comprises a trough (10) into which the upper end (9a) of a discharge pipe (9) opens. The upper edge (10a) of the trough (10) is higher than the edge of the upper end (9a) of the discharge pipe (9). In the trough (10) there is arranged a tubular ring (13), the lower part of which is fitted in the trough (10) and the upper part of which projects upwards, approximately 50 mm to 80 mm beyond the level of the upper edge (10a) of the trough (10), and forms a blocking edge (14). If the rainwater level, when the normal gulleys are blocked, goes over the blocking edge (14), the rainwater is channelled away through the auxiliary gulley. The auxiliary rainwater gulley can be erected on the house roof in exactly the same way and at the same level as the conventional rainwater gulley systems. With the exception of the blocking edge (14), it is similar to the other gulleys and does not require any assembly work. The discharge pipe (9) opens directly above the road surface, with the result that no icing up over a large surface occurs. <IMAGE>

IPC: A47F5/08
Filed: 1977-07-21
Abstract: The articles those for display and sale are hung up by swivel arms which are formed by two or more sections (1, 2, 3) connected together by hinges (5, 6). This means that the outer section which can also be fitted with a lateral support arm (7) can be brought into different positions so that the actual space required need not be great. The inner section (1) of the swivel arm can be fitted on an upright stand by means of a sleeve (4) fitted at one end. It is possible for all the outer sections of several swivel arms to be brought into a position parallel to each other from where they can be easily swivelled sideways to allow easy access.
Patent DE-2737759-A1 (DE)
Title: Sludge-thickening centrifuge - has hollow shaft-mounted drum with cylindrical filter inside drum
Inventor: WIMMER OTTO
IPC: B04B11/00
Filed: 1977-08-22
Abstract: The material to be thickened is supplied into the centrifuge via hollow shaft. Due to the rotation of the drum the solid particles under the effect of the centrifugal force separate from the fluid and are deposited in a ring shape around the shaft. In the same time the solid particles content decreases towards the radial channels. When the full-up condition of the drum approaches, the amt. of solid particles separated decreases, but they are forced instead together with the fluid towards the filter forming an auxiliary filtering layer. The resulting pressure increase inside the drum can be picked up at the hollow shaft inlet. At a point, when no more solid particles are removed by centrifugal force the pressure-operated control system slides shell connecting the two drum parts back and the accumulated solid particles are discharged.

Title: Connection of enamelled wire to component - using soft soldering and closure of circuit including wire and contact when enamel melts to disconnect heat source
Inventor: EDINGER EGON
IPC: H01F41/10
Filed: 1977-09-01
Abstract: The enamelled wire is connected to the component contact element by soft soldering using a measured out quantity of solder and a controlled source of heat. The solder (12) is applied to the enamelled wire (4) inserted into the contact element (3). The wire and contact element are connected to different potentials of a control circuit (15, 16). Then the elements to be connected and the solder are heated, so that the contact element (3) and solder (12) reach the soldering temperature first. When the enamel on the wire melts and contact is established, the current so produced disconnects the heat source (11).
