Title: Heat exchanger with U:tube cluster - has split stabilising plate slotted to prevent tube distortion damage
Inventor: HECKEL JOHANN DIPL ING
IPC: F28D7/06
Filed: 1975-10-22
Abstract: Heat exchanger with tube cluster used in motor vehicles is for gases and has several parallel U shaped tubes. Free ends of tubes are connected to a manifold with inlet and outlet chambers. The tube cluster is supported by a perforated plate near the curve region of the tubes. This perforated plate does not cause damage to tubes on thermal distortion. The perforated plate is split along the tube cluster mid plane into two perforated plates (15a, 15b).

Title: Automatic switch off system for electrically operated fuel pump - has transistorised relay which permits pump to work only when engine is running
Inventor: HENKENHAF GERHARD ING GRAD
IPC: F02D41/30
Filed: 1975-12-20
Abstract: The fule pump (2) is activated by a relay switch contact (14). The relay coil (6) is in series with a transistor (7) whose base has a voltage divider consisting of three resistances (8,9,10). The resistances are respectively connected to signal transmitters (12,13) and the starter motor solenoid (11). The signal transmitters are oil pressure dependent switch and intake air volume sensors, which on a stationary engine give a minus potential. The pump cannot deliver fuel until the starter motor is actuated and will only continue to run while a lubricating oil pressure is present and air is being inducted.

Title: Gas washer for very fine particles - has high speed spray introduced under pressure into relatively slow gas flow
Inventor: KLINKE GREGOR DIPL ING
IPC: B01D47/06
Filed: 1976-01-08
Abstract: Appts. comprises a tube, through which the gas flows, encountering liquid particles at a relative speed of 50-150 m/sec. Flow of droplets is introduced into the tube by one or more nozzles supplied with the liquid at a pressure of >=15 bars. specifically the nozzle is oriented axially to the tube and in the direction of flow of the gas opt. with the gas flow in the opposite direction to the liquid. A succession of nozzles, one after another in the axial direction may be used. Each nozzle may produce a solid or a hollow conical jet. Each nozzle may contain a replaceable twist-producing component, esp. with a central hole. A low gas flow speed with low pressure drop in conjunction with a high liquid injection speed is obtd. thus providing the advantages of a rotary gas washer without the disadvantages of its complicated equipment. There are no moving parts and fluctuations in the gas flow have virtually no effect upong the speed of injection of the liquid.

Title: Reflection polariscope for multiple observation - uses three filters in one housing and indirect illumination for double refraction in optically active materials
Inventor: FICKER ELMAR DR ING
IPC: G01N21/21
Filed: 1976-03-18
Abstract: A reflection polariscope, for measurement of elastic strains from double refraction in optically active materials, uses polarisation filters. It enables multiple observation or direct observation whilst a recording device (e.g. a camera) is fitted. This facility is advantageous for both research and teaching purposes. Several polarisation filters, pref. three, are arranged in one unit. The light source is positioned so that it cannot come in contact with an observer. Light is brought to th epolariser via a deflection system. A zoom lens is arranged in conjuction with the analyser, and the observation fitting may be a measurement optical system or a camera housing.

Filed: 1976-10-07
Abstract: Coherent elongated article (e.g. filament or tape) has a core of a mixt. of a polymer and is not 1 wt. % fibrous reinforcement and a sheath of an unreinforced polymer, all oriented in the longitudinal direction. The polymer pref. is an alpha-olefin (co)polymer, thermoplastic polyester derived from a dicarboxylic acid and a diol with is not 3 C or a mixt. of polymers of these types, whilst the reinforcement pref. consists of glass, asbestos, alpha-alumina, BeO, C, graphite or SiC fibres or steel wires. The core contains pref. 10-50 wt. % (glass) fibre and the polymer in both the core and the sheath is polypropylene or poly(butylene terephthalate). Typical applications include the prodn. of Fourdrinier wires, filter cloths, cables, ropes, slide fasteners, edgings and textiles for upholstery and for reinforcing rubber, e.g. belts and tyres. These filaments are very resistant to flexure and twisting, which cause no fibrillation or sepn. of the core and sheath. They can be bent like a wire and have a much lower elasticity than commercially available monofilaments. They have the expected stiffness, strength and low thermal shrinkage and can also be crimped.

Title: Semiconductor detector prodn. using planar techniques - forms several detectors on silicon disc whose front junctions are produced by implantation
Inventor: KEMMER JOSEF DIPL PHYS DR
IPC: G01T3/08
Filed: 1976-10-28
Abstract: Certain steps of the planar technique are combined in the production of the semiconductor detectors, such as surface passivation, photolacquer masking, ion etching and ion implantation, in a manner obviating the use of high temperature processes. In this manner several detectors are produced on a silicon disc. The front side pn-junctions of the detectors are produced by implantation, using very small window thickness. The rear contact is formed by an implanted layer of defined surface resistance. The polished or ion etched silicon disc is first passivated by a protective film and windows are opened, using a photolacquer mask by chemical treatment or ion etching. The protective film is stripped completely from the rear. The front side is treated by ion implantation in specified manner. Finally a temperature activation and possibly metallising completes the process.

Title: Strip marking detection equipment - has two photoelectric detectors which deliver signals to differential amplifier with filter to suppress negative voltages
Inventor: KRUMEY FRIDHARD DIPL ING
IPC: B65H23/04
Filed: 1977-04-09

In the travel direction (3) of the strip (1) there are two detectors for the marks (4), preferably photoelectric cells (9a, 9b) close one behind the other. A differential amplifier compares the voltages across the detectors, and initiates a control operation if these are unequal. The amplifier may be followed by a filter for suppressing negative voltages, and the light-sensitive portions of the cells may be oblong in shape, extending at right angles to the travel direction. Each can extend beyond the likely position of the strip edge for the same distance, and over all possible positions of the marks.

Title: Twisting wire left to right - using two twisting heads rotating round the twisting axis
Inventor: MATOUSEK HEINRICH
IPC: D07B3/00
Filed: 1977-04-09
Abstract: Process uses two twisting heads, rotating at a constant speed round the twisting axis, alternately acting on the material to be twisted. The rotary speed and/or the rotary direction is different for both heads. At least one roller in each twisting head moves radially to the rotary axis of the twisting head. An electromagnetic field is used to exert movement on at least one roller in the twisting head, or the movement can be imparted by mechanical, hydraulic or pneumatic means. The rollers of each twisting heads are at least partially replaced by runners sliding over the material being twisted. The system allows a high speed wire twisting operation, with very short twist change points, in a simple and trouble-free process.

Title: CONCN. AND PURIFICN. OF SULPHURIC ACID FROM TITANIUM DI:OXIDE MFR. - by boiling in presence of ferrous sulphate to remove chromium
Inventor: BRAMEKAMP KARL-JUERGEN DR
IPC: C22B34/12
Filed: 1977-07-01
Abstract: The process concerns the removal of Cr ions in the concn. of dil. H2SO4 solns. contg. FeSO4 from TiO2 pigment mfr. by evapn. of water and sepn. of FeSO4, the soln. being conc. to 60-70 wt.% H2SO4, as in DT 2618121. The novelty is that the dil. or pre-conc. acid, contg. is not 500 g. FeSO4/g. Cr to be removed, is kept at the boil at is not 130 degrees C. Cr is pptd. if the required amt. of FeSO4 is present and better pptn. is attained at higher temps. Higher temps. also favour the pptn. of FeSO4.H2O in easily filtered form. The FeSO4 content can be controlled by selection of the crystallisation conditions for FeSO4.(H2O in pigment mfr. or by adding solid hydrated FeSO4 to the dil. acid before concn. After sepn. of the pptd. metal salts, the conc. 60-70% acid pref. is treated with solid hydrated FeSO4 to give up to 2000 g. FeSO4/g. Cr to be removed and then boiled for 2-4 hr., after which the FeSO4 added and other pptd. metals salts are sepd.
