Title: Stabilised guide for linear induction motor vehicle - lateral flanges sloped away to zero height at switching points
Inventor: WINKLE GUENTHER DIPL ING
IPC: B60L13/00
Filed: 1974-12-06
Abstract: The linear induction motor has a pattern of metal laminations wound about with electric windings and supported above a flat metal guide rail (7) by an air gap. In order to ensure the lateral stability of the vehicle, special side flanges (9, 10) are fitted to either side of the rail to contain the moving section.

Title: Strip and matrix joining profile extruding tool - has curved strip inlet channel with friction reducing rollers
Inventor: AMES ADOLF
IPC: B21C25/06
Filed: 1975-03-14
Abstract: The arrangement for extruding composite profiles produces a composite profile consisting of at least two combined, joined profiles. Strips or profiles are guided into the material flow, especially into a light alloy matrix through guide channels in the tool. This arrangement is also suitable for connecting unplated metal strips firmly with the matrix. Friction between the metal strip and extrusion tool is avoided and the economical production method can be used for a wide range of applications. The guide channel curved section has rollers which rotate for reducing friction on the strips (1, 2). These rollers can be arranged into cages held in the guide channels so that they can be readily replaced.

Title: Linear generator with reciprocating pistons - converts piston energy directly into electrical energy and vice versa
Inventor: WILLIMCZIK WOLFHART DIPL PHYS
IPC: H02K35/00
Filed: 1975-05-05
Abstract: The direct conversion machine replaces the electrical energy plant with reciprocating piston engine which drives a rotating generator. The direct conversion machine can be used as a diesel electric traction unit in ships and locomotives and also in passenger road vehicles. The two cylinder, two stroke, engine (1) has pistons whose connecting rods are directly connected to the linear generator moving part (3). The only moving part is formed by the assembly of two pistons with the generator moving part. Electrical energy is absorbed from the linear generator for overcoming dead centre effects of the reciprocating pistons and hence no mechanical devices are needed for piston actuation.

Title: Mortarless sloping roof ridge coping stone - with bottom edges angled and shaped to fit tops of tiles
Inventor: GERHAHER MAX DIPL ING
IPC: E04D1/30
Filed: 1975-09-10
Abstract: The coping stone, on a sloping roof, is designed so that it can be fitted on the roof tiles lying below it, without using mortar or shaped pieces, and laid on standard centre-field roof tiles. This is achieved by shaping its base edges (2), which stand at an angle onto the roof tiles (3) lying just below it on both sides, so that the base edges fit the upper face shape (4) of these. The stone body (1) may be conical in horizontal longitudinal section, with the outside face of the covered end dimensioned in proportion to the inside face of the covering end. In the area of the former end, the base edges can match the slope of the roof by chamfered seating surfaces, which run at a constant angle as far as the covering end.

Title: Saturated steam sterilisation system - has cold water heat exchange removed from system for steam production
Inventor: HUBER JOAHANN
IPC: A61L2/07
Filed: 1975-12-29
Abstract: The sterilization system is for use with large sterilizer devices which are fed from a remote steam source. The material to be sterilized comes into contact with saturated steam and has cold water extracted from the recondensed sterilization steam. Sterilization steam is generated from warm water heated during heat exchange from the condensing steam. The extracted cold water separates into warmer and cooler sections as a result of the different specific gravities occuring in the water as a result of temperature variation.

Title: Hydraulically operated mitred profile joining machine - has clamping mechanism guide fully retracted under machine table and sensors
Inventor: VEGA MANUEL PRIEGO
IPC: B21D53/74
Filed: 1975-03-13
Abstract: The fixture is used for joining two mitred corners cut into metal profiles for forming frames by a corner connection pushed into these hollow profiles. The frame is placed into the machine and it is no longer swung upwards and hence only one machine operator is needed. The machine has a support for the metal profiles, and a stop for the mitred joint outside edge. Pressing tools are provided for pressing the wall elements into the profiles. The guide for the clamping piece is a guide column under the mounting face. This guide column can be pivoted about a joint so that the clamping piece can be fully lowered below the mounting face in the retracted position. The machine has hydraulic actuators and sensors for ensuring correct assembly.

Title: Open air swimming pool side walls icing protection - uses coating of plastics panels at expected ice level
Inventor: MAISENHAELDER SIEGFRIED
IPC: E04H4/06
Filed: 1976-03-15
Abstract: The process is esp. suitable for application to open-air swimming-pools where the sidewalls must be kept free of ice which might exert excessive pressure on them in winter, although the water must remain in the pool because of the proximity of groundwater. For this purpose the sidewalls (2) are coated with plastic panels (3) at the level of the area of the max. layer of ice (1) to be anticipated. The panels can have a bent-over supper area overlapping the top edge of the pool, and be loaded with weights in their lower area. They may overlap each other sideways, pref. with a tongued and grooved connection in this area (4). The panels may have an impact-resistant coating (7) on the side facing the ice layer, or on the other side (8). They can be removable in summer.

Title: Gadolinium gallium garnet crystals for magnetic bubble memories - grown in protective atmos. which increases life of iridium crucible
Inventor: MATEIKA DIETER DR
IPC: C30B15/00
Filed: 1976-04-09
Abstract: Single crystals based on rare-earth Ga garnet, are made by the Czochralski process using an Ir crucible in an oxidising atmos. which consists, at least in part, of CO2. The gas atmos. pref. consists (a) entirely of CO2; or (b) 75-90%, esp. 80% of N2. The process is esp. employed for mfg. single crystals of gadolinium-gallium garnet starting from materials which are previously sintered 1-7 days at 1500-1750 degrees C. Although previous inventions prevents the loss of Ga2O3 and/or Ga2O during the process, they ignore the high loss of lr which can occur, e.g. 9-15 g, in a conventional atmos. contg. 98% N2 and 2% O2. The invention preserves the crystal perfection of the garnet obtd. while reducing the loss of lr to below e.g. 0.03 g/hr.

Title: Photographic information display device for camera - with exposure data stored in shift registers, gives segmental digital display
Inventor: MURAKAMI HIROYASHU
IPC: G03B17/20
Filed: 1976-04-14
Abstract: Clock pulses from a generator are used for generation of sequential signals, which are decoded and displayed. Each of a row of segmental character display devices has the usual seven display segments plus an eighth segment which is not normally used. A signal delivered from a decoder controls the eighth segment and controls the operation of additional display devices. These additional display devices may be two light-emitting diodes situated respectively before and after the row of segmental digits. The segments are preferably light-emitting diodes. The first of the two additional diodes is illuminated when the exposure time is less than one second. The other additional diode indicates that exposure is under manual control.

IPC: B60R13/10
Filed: 1976-04-14
Abstract: A non corrosive metal plate (2) is stamped with process information in two areas; one binary and one as a series of numbers for visual identification. The card information relates to individual requirements for that particular body e.g. right or left hand drive. The plate provides a fail-safe check for the process variations, especially if it is read by automatic controls which indicate to the relevant operators which modifications are to be made. The machine readable binary stampings in the plate can be used to index e.G. a multi spindle drilling head. The plate is galvanised against corrosion.
