Patent DE-2410251-A1 (DE)
Title: Welding plates together longitudinally - on continuous line comprising posi-tioner, welder, plate turner, bead dresser and inspection station
Inventor: HEROLD KARL
IPC: B23K37/04
Filed: 1974-03-04
Abstract: Individual plates are positioned by powered rollers and stops at the entry end of the line, before progressing to the welding station where the top side is welded. The partly welded plates then pass to the next station where they are turned over and returned to the welder for the other side to be welded. The completely welded plate then passes beyond the turn over machine to the bead dresser for removing excess weld metal on the upper surface, then back to the turn over machine, and then back to the bead dresser where the excess metal is removed from the other side of the plate. Finally, the plate passes to an inspection station. Productivity is increased by not having to take the plate away from the machine for turning over, and by allowing work to commence on a new pair of plates while the previous pair are being finished at the other end of the line.

Title: Program controlled domestic appliances - have an electronic program control suitable for washing cycle for clothes or dishes
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: G05B19/07
Filed: 1974-03-12
Abstract: The programme control consists of a counter with several series connected counting stages. Each counting position is assigned to a programme segment. On completion of a programme segment, a counting signal is produced and passed to the counter. Part of the programme control is divided into a basic programme and a subroutine. The basic programme comprises all the main operations, which are repeatedly run through by the comparison elements and/or the timing elements. The subroutine supplies the various settings. The counting positions of a second counter are assigned to stages for the comparison and timing elements.

Title: Twisted glass fibre cord - uses strands clad with a thermoplastic or elastomeric before twisting
Inventor: EULE WERNER DIPL ING
IPC: D07B1/02
Filed: 1974-03-16
Abstract: The system to twist strands of glass fibres into a cord, such as for industrial conveyor belt applications, uses a thermoplastic or elastomeric cladding for the glass fibres before they are twisted. The system gives protection against abrasion between the strans when they are twisted, to give a flexible and strong cord which can be wound can be wound round a drum. The cladding material can be a PVC or a natural or synthetic rubber. The glass fibre strands are either attached to each other by the thermoplastic or elastomeric material, or are individually clad with the matl. The result is a strong glass fibre material with about 100% stretch without the individual strands tearing or breaking.

Title: Chair with height-adjustable head and neck rest - has spring-biased guide for head rest allowing easy adjustment from any side
IPC: A47C7/38
Filed: 1974-06-19
Abstract: The car seat or doctor's chair is provided with a vertically adjustable spring-loaded guide (2, 3) which is connected to the back rest and is designed for the easy adjustment of the head and neck support (1). The backrest (18) of the seat is designed to swivel backwards and forwards about an axis (17) so that when moving the back rest out of the normal upright position the patient can keep the support firm against the neck or head so that the support follows the movement of the latter. The position of the head rest can be altered merely by moving it by hand against the spring force but this same spring force allows the head rest to keep its position. The guide for the support can be formed by grooves wherein the retaining parts (6, 7) of the head rest which engage in the grooves are biased relative to each other by one or more springs.

Title: Fuse board for multiple path assemblies - has forked contacts holding fuse terminals
Inventor: PECHE GERHARD
IPC: H01H85/20
Filed: 1974-08-14
Abstract: The multiple path assembly has one pole earthed and can take both excess current and excess voltage protection links, for example as used in telecommunications installations. The fixed terminals (3), which are located in an insulated board (1), are in the form of a fork with contacts. The contacts may have projections to form a larger opening to take the fuse tag. This tag, which is typically made from a hollow rivet whose end has been squashed flat, is pressed into the fork so that the contacts are forced apart giving a resultant spring pressure to give both location and electrical connection. The fuses (2) are thus readily exchangeable.

Title: Rough steel reinforcing rod for concrete - is held in nut thread by means of wedging produced by driving through with double-sided rolled thread ribs
Inventor: WOLTER RUDOLF
IPC: E04G21/14
Filed: 1974-11-11
Abstract: The holding system is for non-smooth concrete steel bars in an internal matrix thread, by means of a wedging action produced by striking and driving through, especially by driving through threaded steel bars with thread ribs rolled onto both sides. The threaded socket, for the process of striking and driving through, can incorporate a reinforcement, fitted with an internal matrix thread, with a ring plug configuration at both ends or in the central area. An example of use is with short concrete rib steel bars for a shear-stress-resistant union with concrete, such as a door steel bar, slightly pointed, driven through threaded holes in the girder cross arm.

Title: Electronic thin film solid state circuits prodn. - by high frequency sputtering from cathodes onto dielectric or semiconductor substrate
Inventor: CORSI CARLO
IPC: H01L21/363
Filed: 1975-06-25
Abstract: In the prodn. of electronic thin film solid state circuits, a film of a substance is deposited on a dielectric or semi-conductor substrate by high frequency sputtering from a number of cathodes. The constituents of this substance are present in predetermined concn. ratios and different ratios are obtd. by changing the electric parameters of networks between the high frequency generator and the individual cathodes. The use of the process for depositing a film of PbxSn1 -xSe, HgxCd1-xTe or In1-xAsxSb is also claimed. The temp. needed for the prodn. of an epitaxial structure is much lower than usual, allowing its use with substances (e.g. Ge and some binary and ternary semiconductors) which cannot be used at the higher temps. The substance is kept at a temp. within a range preventing selective re-vapourisation of individual components with a relatively high vapour pressure. In an example epitaxial films of PbxSn1-xTe, e.g. on Ge were produced by sputtering with pure Ar at 5 x 10-4 to 5 x 10-3 torr with a 1000 V discharge, substrate temp. of 200-400, pref. 280-350 degrees C and a deposition rate of under 1 mu m/h.

Title: Pushpull modulator for SSB systems - has frequency dependent negative current and voltage feed back to reduce unwanted side band
Inventor: TAUBMANN PETER DIPL ING
IPC: H03C1/54
Filed: 1975-08-14
Abstract: The negative feedback is made frequency dependent in such manner that lower feedback occurs for the wanted sideband than for the unwanted modulation products. The negative feedback consists of a combination of current and voltage feedback. The mitters of the push-pull transistors are connected over two transistors (15, 16). These resistors are shunted by a frequency dependent dipole (8, 17) consisting of an inductor and resistor, or of an LC parallel combination in series with a resistor.

Title: Casting moulds made of green sand - with subsequent spraying of carbonaceous aerosol on mould surface contours
Inventor: SIEDLER RICHARD
IPC: B22C11/00
Filed: 1975-08-22
Abstract: Casting moulds and cores are prepd., from green sand, from a mixt. of sand, bonding medium and additives but without the org. matter normally added to prevent its burn-on to the casting. The halves are then sprayed with carbon in liq. or powder form or other material which is turned into vitrain by the heat of the poured molten metal. This greatly reduces the amt. and cost for the addn. of carboneceous matter. The carbon dust conditions in a foundry are improved. The cost for drying, required if blackwash is applied manually, is saved. Pipe clogging and vapours from oily additives are eliminated.
