Title: Calcium sulphate whiskers with high length:dia. ratio - used as filler and/or reinforcing material in natural or synthetic rubbers
Inventor: KYRI HANS DR
IPC: C08K7/08
Filed: 1977-01-19
Abstract: Calcium sulphate whiskers with a ratio(R) of length:average cross-section of min. 6:1 are used as a filler and/o rreinforcing material in rubber mixts. The whiskers are obtd. from a hot, aq., acid soln. contg. CaSO4, and which is free from crystal nuclei; the soln. is cooled to 65-40 degrees C., and held at this temp. until the saturation concn. is reached, so the whiskers crystallise out and are sepd. from the soln. Cross-linked-, and/or non-cross-linked- natural and/or synthetic rubbers may be used, esp. using 1-150 pts. calcium sulphate whiskers per 100 pts. rubber. The whiskers include calcium sulphate hydrate whiskers, and are normally 0.005-0.03 m thick with R pref. min. 20:1 and e.g. 100-160:1. They are used as fillers, opt. with glass- or asbestos-fibres, in coatings, foils, paper. cardboard etc.

Title: Natural gas power station - has turbine by=pass with accelerator to store exhaust and maintain constant pressure
IPC: F02C1/00
Filed: 1977-02-17
Abstract: The tubine (1) is fed by natural gas (3) via a regulator valve (14). The gas pressure is reduced by passing through the turbine blades and the reduced pressure is passed on to the consumers via feed pipe (4). The turbine energy received from the gas flow is used to turn an electric generator. A by pass (12) containing a pressure reduction valve (13) can be connected between the natural gas main supply (3) and the consumer to maintain the turbine exhaust (4) at a constant pressure. A second by pass could also be provided and containing a jet compressor (17) at the junction with the turbine exhaust (4). The jet compressor increases the exhaust pressure which is stored in a container (5).
Patent DE-2713327-A1 (DE)
Inventor: RITTER KLAUS DIPL ING
IPC: E04C5/06
Filed: 1977-03-25
Abstract: The spacers have two parallel longitudinal bars (1, 2) which undulate in the form of a zigzag. A connecting bar (3) which is likewise in the form of a zigzag is welded in between the two longitudinal bars (1, 2). The "wavelength" (Lb) of the longitudinal bars is substantially greater than that (La) of the transverse bars. This design permits a continuous production of the spacers with a small degree of material consumption. <IMAGE>

Title: Rotary tubular furnace for combustion of solids - has circumferential combustion air inlet channels at points along its length
Inventor: LOHMANN HARRY ING GRAD
IPC: F27B7/02
Filed: 1977-03-28
Abstract: A rotary tubular furnace is made in several sections, each section having a larger dia. than the preceding one from inlet to outlet ends. The furnace rotates around an axis that falls slightly from the horizontal from inlet to outlet. Solids are fed in from the smaller dia. end and gradually burned along the furnace length with the air of support combustion close to the inlet. At the point where sections of different dia. join combustion air is fed into the furnace through the bed of solids. The combustion air is blown in from annular air bustle through channels made between the overlapping refractory lining ends of each section. This air is fed along the length of the furnace to each circumferential inlet by air junction channels positioned between the refractory and the furnace casing. Used for the combustion of solid wastes usually in a paste-like form. Air is fed into the burning bed which increases combustion intensity, shortens the length of furnace required and reduces the excess aire requirements and the pollution.

Title: Inflatable body press. control unit - uses pressure dependent switch for pump motor drive dependent on pressure level
Inventor: KREUZER HELMUTH
IPC: G05D16/20
Filed: 1977-07-18
Abstract: The device is for controlling the pressure in an inflatable body with a motor driven pump, a press. connection between pump and body, a non-return valve, and a measurement pipe between body and a press. dependent electrical switch. It is designed to operate without continuous operator monitoring and continuous motor operation.

Patent DE-2734235-A1 (DE)
Title: Pattern dyed fabric washing - uses fluid and a dwell time to swell and release surplus paste dyestuff
IPC: D06P5/02
Filed: 1977-07-29
Abstract: The washing stage to remove surplus paste dye from pattern printed fabric uses an application of fluid to swell the paste thickener, using a defined fluid volume to achieve the swelling. After a dwell time, the surplus paste dye can be removed from the fabric. The fabric is allowed to dwell in air, hanging in loops without adjacent loops being allowed to touch each other. The dwell phase can be restricted to 20-30 secs., after which the swollen dye is released. This stage can be repeated, if necessary, before being chemically washed by a fluid being passed through the whole material. The process ensures that surplus paste dye is easily removed from the material before it enters the final chemical washing stage.
Patent DE-2740764-A1 (DE)
Title: Semiconductor device prodn. on crystal disc surface - uses resist masks produced by electron beams with program controlled impingement spots
Inventor: RUECHARDT HUGO DIPL PHYS DR RE
IPC: H01L21/027
Filed: 1977-09-09
Abstract: In the production are used at least two resist masks, each being applicable for production of a structure on the semiconductor surface and/or on a covering layer, e.g. by etching. Each mask is produced by an electron beam whose impingement spot is program controlled on the respective surface side of the semiconductor crystal. During production of the subsequent resist mask the impingement spot of an electron beam is guided over a resist layer forming the base of the mask. For this purpose is used a sensor operating in a coordinate system in dependence on the previous structuring step formed by stray electrons in the heterogenous surface. The sensor controls an evaluator affording direct position correction.

Title: Detection, storage and reproduction circuit for change of state - has registers for actual and comparative states and has comparator with timing generator
Inventor: ULLRICH KLAUS
IPC: G07C3/08
Filed: 1977-10-13
Abstract: The change-of-state detection, storage and reproduction circuit has a comparator (8) which, when changes of state are detected and stored, transmits an output signal where the contents of the two registers (4, 9) are unequal. This output signal triggers a command to store the value of a counter (3), together with the content of the register for actual states, in an event memory (6). The signal also causes the content of the register for actual states to be transferred to the register for comparative states and the address counter (13) to be switched on by one step.

Title: FET with insulating support and insulated gate - has lightly doped zone under gate, in which space charge zone is produced by operating potentials
Inventor: KRANZER DITMAR DR
IPC: H01L29/786
Filed: 1977-12-14

Title: Auxiliary electrical power supply for motor vehicle - has generators on trailer driven by road wheels to reduce fuel consumption
Inventor: SHOKOUHBEEN RAHIM
IPC: H02K53/00
Filed: 1978-06-06

Title: Braking control with dynamic retarder - will inhibit during emergency braking on conventional system to allow good brake balance
Inventor: MUSCHELKNAUTZ HORST DR ING
IPC: B60T8/40
Filed: 1978-06-07
Abstract: The vehicle is braked by a combination of dynamic retardation and friction brakes, with a simple comparator on each wheel to adjust the relative braking reactions of both systems. For emergency braking the dynamic effects are removed so that a controlled braking balance is possible between the front and rear brakes. The dynamic brake reduces brake pad wear and provides a smoother driving control. The inhibit interlock prevents rear wheel lock in full braking, with the anti-skid control being able to reduce the rear brake force to any minimum level.
