Patent DE-2433947-A1 (DE)
Title: Heat engine for converting heat to kinetic energy - preventing pollution by constant combustion, using any combustible material
Inventor: THURN JUN KARL
IPC: F02G1/02
Filed: 1974-07-15
Abstract: Heat engine for converting heat to kinetic energy comprises a cylinder in which the state of aggregation of a fluid medium is varied by heat applied from externally, so that the resulting gas pressure produces kinetic energy. In stage 1, the piston is at TDC, the exhaust port is open and internal and external pressures are equal; in stage 2, the piston compresses residual gases, and water is injected; in stage 3, the water is compressed between heating fins to evaporate it; in stage 4, the pressure caused by evaporation drives the piston upwards again so that the exhaust port is re-opened.

Title: Waste heat utilization of dry coke quenching recycled gases - by after combustion of side stream for temp. stabilization
Inventor: MINASOW ALEXANDR NIKOLAJEWITSC
IPC: F22B1/04
Filed: 1974-08-06
Abstract: The recycled gas produced during the dry coke quenching operation which contains combustible components is burnt and passed through a waste heat boiler to generated steam. In case the thermal energy data of the steam in the waste heat boiler deviate from a preset constant level, the recycled gas passes through an after combustion zone where a mixture of air and fuel, natural or similar gas is added to it at 1000 to 1200 degrees C. This is a simple and inexpensive means of keeping constant the parameters of the steam produced in the waste heat boiler, independent of fluctuations in the coke dust content of the recycled gas. The risk of explosions is effectively eliminated.

Title: Welded screw seam tube mfr. - from steel strip or from sections of sheet metal
Inventor: WEIDNER HELMUT ING GRAD
IPC: B21C37/12
Filed: 1974-08-08
Abstract: Tube is mfd. from strip by feeding the strip from a coil to a cutting arrangement in which the strip is slit into two parts and in which the sides of the strip are also machined. When the tube is made from sections of sheet metal, the sections are first fed into a cutter in which front and end faces of the sections are machined. The sections are then fed to a welder in which the sections are welded to one another into a strip after the strip is fed into the strip cutting arrangement. The strip is slit into two, after which each of the two strips is fed to a conventional tube forming and welding machines such as a three roller bending machine machine.

Title: Data transmission with clock frequency phase control - generates response signal at transmitter from information ssssiggggnall
Inventor: SCHOLLMEIER GERO DR ING
IPC: H04L27/06
Filed: 1974-05-14
Abstract: The partial response signal and the information carrying signal are recovered at the receiver for demodulation. The clock frequency phase is adjusted at the receiver by a clock frequency recovery circuit, and an error signal is derived by an error stage which signals the deviation from normal of the signal delivered by the decision stage. The clock frequency recovery circuit contains a summator which adds with negative polarity the information signals delayed by one clock period and by four clock periods, and with positive polarity and double amplitude the signal delayed by two clock periods, and delivers a sum signal; the clock frequency recovery circuit contains further a multiplier for the product of the sum signal and the error signal delayed by one clock period.

Alternatively, the reaction can be effected in an aq. or organic diluent at the b.pt. of the mixt. The product gases are pref. continuously removed by passing air or an inert gas over the reaction mixt., or by applying a vacuum.

Title: Electromagnetic movement or actuator system - comprises two outer magnets and system includes inner magnet moving between them
Inventor: LAMMERS ALBERT
IPC: H02K35/04
Filed: 1975-03-08
Abstract: In the invention, there is an inner magnet (1) which is positioned between two outer magnets (A1 and A2) and it is attracted and repelled by one or the other of the outer magnets as the result of continuous polarity reversal due to excitation by alternating current. The inner magnet is specif. a circular or four-sided slab magnet which is positioned with its ends housed in apertures in the outer magnets. This apparatus is used for producing linear or reciprocating motion. Alternative versions of the apparatus may be used to produce rocking motions or limited circular motions.

Patent DE-2516096-A1 (DE)
Title: Arc welding current source - with pulse capacitor discharging for arc striking/stabilizing when thyristors/triac are fired
Inventor: BODEWIG PETER
IPC: B23K9/09
Filed: 1975-04-12
Abstract: The welding current source for an electric arc welding plant includes a welding transformer with two anti-parallel phase-controlled thyristors or one triac in its primary circuit. The pulses to strike or stabilize the electric arc are produced by a storage capacitor which is connected in series with the antiparallel thyristors or triac in the primary circuit of a pulse transformer and discharges when they are fired. The secondary winding of the latter lies in series with the secondary winding of the welding transformer. This only requires an inexpensive storage capacitor to produce exactly synchronized stricking pulses. The pulses also achieve an arc stabilization by simple and reliable means.

Title: Bis-(4-chlorophenyl)-sulphone recovery - by crystallisation from chlorobenzene sulphonic acid reaction prodt liquors
Inventor: HORNER PATRICK JAMES
IPC: C07C317/14
Filed: 1975-12-09
Abstract: Bis-(4-chlorophenyl)-sulphone (I) is sepd. from reaction productts obtd. by reacting chlorobenzenesulphonic acid (II) with chlorobenzene (III), by (a) if necessary adjusting the ratio III/II to form a crystallisation liquor, (b) cooling the liquor to a point where (I) crystallises out and (c) sepg. the crystalline (I) from the mother liquor, whereby the ratio III/II in the crystallisation liquor is such that the amt. of crystalline (I) obtd. differs from the maximum amt. of crystalline (I) which it is possible to obtain by adjusting the ratio III/II in the reaction product by a maximum of 10 g per 100g of the mother liquor which it is possible to obtain by crystallising (I) from a reaction product whose ratio of III/II has not been adjusted.

Patent DE-2557586-A1 (DE)
Title: Torque controlled transmission with constant fluid supply - uses secondary pump driven by wheels to allow towing or bump starting
Inventor: KUHN WALTER DIPL ING
IPC: F16H61/00
Filed: 1975-12-20
Abstract: The torque controlled transmission has friction clutches operated by hydraulic pressure, with the fluid supply also coupled to other users such as torque converter etc. A primary pump driven by the engine supplies most of the fluid while a secondary pump driven by the transmission output shaft delivers a smaller supply. This ensures adequate fluid supply if the vehicle is being towed. The primary pump is coupled to the secondary supply by a simple non return valve, while some parts of the hydraulic circuit are coupled directly to the secondary pump. Both pumps operate when the engine is running and the vehicle moving. No complex valving circuits are required to ensure constant lubrication of the system when towed. Also the engine can be started by towing the vehicle or rolling downhill.

Abstract: The machine forms staggered overlapping sheets into a stack, the incoming ones (12) travelling at constant speed through an inverter mechanism. After this the foremost sheet, now travelling in the opposite direction, is held both at the leading and the trailing edge until it reaches a position above the stack, whereupon it is released. The incoming sheets can be delivered lying on a conveyor belt (10), being then taken over by other transporting devices such as suction cups (8) or grips, engaging with their leading edges and guiding them to the discharge point above the stack.
