Title: Process for lightening and stabilising the colour of fatty acids
Inventor: STRUVE ALFRED DIPL CHEM DR
IPC: C11C1/10
Filed: 1982-08-26
Abstract: The lightening and/or stabilising of the colour of fatty acid or fatty acid mixtures is effected by a vacuum distillation of the starting material to be purified with the addition of arylphosphorus sulphide. The starting material to be purified is preferably initially subjected to a thermal pretreatment at at least 150 DEG C under moderately reduced pressure. The amount of arylphosphorus sulphide which is then added is expediently not more than about 1 % of the weight of the distillation mixture. The concluding distillation is expediently carried out in the pressure range from 0.1 to 10 mbar.

Title: Device for detecting the gas portion in a fluid system under pressure
Inventor: THOMSEN SVEND ERIK
IPC: F15B21/044
Filed: 1982-09-10
Abstract: In a device for detecting the gas portion in a fluid system under pressure, such as the air portion in a hydraulic system, there are two fixed restrictors (5, 6) which form a series circuit (4), through which the same fluid quantity flows, between a pressure-conducting part (2) and the low-pressure side (3) of the system. To detect the gas portion, the pressure drop can be measured at one of the restrictors (5, 6). The measured pressure drop can serve in particular to control a discharge valve (20) if the gas portion assumes an inadmissibly high value. <IMAGE>

Title: Gear for converting a low torque into a high torque
Inventor: BUCHENBERG KONRAD
IPC: E05F15/622
Filed: 1982-10-15
Abstract: The invention relates to a gear, for example for an electromotive door drive. The object of the invention is to design an electromotive door drive in such a way that, whilst being of compact construction, it can also be mounted on the pillar at a distance from the door inner face and, moreover, has a very high torque transmission ratio in a compact construction. According to the invention, a spindle nut of a threaded spindle of relatively small thread pitch has driving arms which pass simultaneously through the straight slot of a drive cylinder, for example for the door drive, and the helical slot, provided with a very high pitch, of a stationary guide cylinder. The entire arrangement works with very high efficiency in a very confined space. The threaded spindle, driven at a high speed, for example by an electric motor, and having a low pitch, moves the spindle nut upwards and downwards. The driving arms connected firmly to the spindle nut engage externally into the helical slot of a stationary guide cylinder. The high pitch of the outer guide cylinder forces the spindle nut to execute a pivoting or rotating movement.

Patent DE-3301372-A1 (DE)
Title: Hydraulic control device
Inventor: SANDAU HARTMUT DIPL ING
IPC: B60T13/16
Filed: 1983-01-18
Abstract: The hydraulic control device has a flow control valve (16) and a brake device (51, 52, 71, 89). In a braking sequence the pressure medium delivered by a pump (13) is controlled by way of the flow control valve and a non-return valve (38) to the brake cylinder (89). At the same time pressure is exerted on a little piston (52) together with slide valve (51), by means of which the latter is so adjusted that a flow of control oil from the pump to the tank is interrupted and pressure medium can flow to the brake device. There follows a build-up of pressure in the brake cylinder (89) in a plurality of stages, since after each initial build-up of pressure by way of the little piston (52) and the control slide valve (15) there is a fall in pressure. In the event of further operation of the brake pedal there follows the next pressure stage. The more pressure stages can be produced, the more accurately the brake pressure can be maintained. This is done by means of a valve body (103) on the control slide valve (15) which ensures that the control slide valve moves faster in the one direction, slower in the other, which contributes to the correct build-up of pressure in the brake cylinder (89). <IMAGE>

Title: Power semiconductor module and method of triggering it
Inventor: BECHTELER MARTIN DIPL ING DR
IPC: H01L25/16
Filed: 1983-01-31
Abstract: Semiconductor modules embodying two semiconductor bodies (5, 6) which can be individually triggered via two LEDs (10, 11) require a housing having at least 3 triggering connections. It becomes possible to use the standard module housing (1, 2, 3) having two triggering connections (12, 13) if the LEDs (10, 11) are connected in antiparallel between the two triggering connections (12, 13). Transistor switches which can be operated with high frequency for quasi-simultaneous triggering and are operated in push-pull, for example, are suitable for the triggering. <IMAGE>

Title: Yagi antenna array with a sector-shaped polar diagram
Inventor: HOLLMANN HEINRICH DIPL ING
IPC: H01Q19/28
Filed: 1983-04-29
Abstract: The invention relates to a Yagi antenna array, having a plurality of Yagi antennas arranged in a row, in which, in order to achieve a sector-shaped polar diagram, the outer Yagi antennas are loaded in antiphase and at a reduced amplitude in comparison with the inner Yagi antennas. The object of the invention is to create a sector antenna having dimensions which are as small as possible and having a simple network structure. This is achieved in that three Yagi antennas are provided and in that the reduced amplitude loading of the two outer Yagi antennas 6, 7 is effected to a first approximation by means of a commercially-available attenuating element 4 having values which are graduated in an integer ratio with respect to one another; the optimisation with respect to the desired sector-shaped polar diagram is effected by means of a considerably lower gain for the two outer Yagi antennas 6, 7 in comparison with the inner Yagi antenna 2, which is achieved by means of a considerably smaller number of directors 40 to 42 in comparison to 17 to 22 and by means of correspondingly different lengths and mutual separations of the antenna elements which determine the gain; finally, the respective distance 12 of the antenna axis of the two outer Yagi antennas to the antenna axis of the central Yagi antenna 2 is in this case selected with respect to the operating wavelength W such that the second null point of the sum polar diagram of the two outer Yagi antennas [lacuna] with the half-beam angle of the sector diagram...

Title: Process for the acid hydrolysis of polysaccharide-containing materials
Inventor: FICK ELMAR PROF DR RER NAT
IPC: C13K1/02
Filed: 1983-06-16
Abstract: In a process for the acid hydrolysis of polysaccharide-containing materials, especially for obtaining glucose from cellulose-containing raw materials, first the pentosans contained in the raw material are hydrolysed with concentrated orthophosphoric acid to pentoses and filtered off together with the orthophosphoric acid. The hexosans remaining in the filter cake are subsequently hydrolysed with pyrophosphoric acid, which has been obtained from the orthophosphoric acid by evaporation, to hexoses. The hexoses and pentoses are separated from the phosphoric acids by extraction with an organic solvent (for example butanol, isopropanol), the pyrophosphoric acid previously being converted back into orthophosphoric acid. Subsequently, the organic solvent is removed from the orthophosphoric acid by distillation and, just like the latter, used again. <IMAGE>

Title: Buoyant structure for delimiting surface contamination on stretches of water due to oil or the like
Inventor: LINGNAU ALFRED DIPL ING
IPC: E02B15/04
Filed: 1983-10-20
Abstract: Buoyant structure for delimiting surface contamination on stretches of water due to oil or the like, produced as an endless structure, and, while including the sub-claims, constructed according to the drawing, Figs. 1 + 2, as a radiating symmetric arrangement of tubes which are connected to one another, spirally orbit the longitudinal axis of the structure and are filled with water to such an extent that water pockets form in the lower tube curves, which water pockets seal off the overlying air chambers from one another. On account of high flexibility and elasticity, the structure is only exposed to slight forces, uses less material due to the absence of adhesive or weld spots, and is virtually unsinkable on account of the many separate air chambers, so that it can be constructed with very thin walls. The fact that little material is used suggests that the structure can be made at the place of use, which essentially requires an extruder with a rotating discharge shape through which the structure is at the same time filled with gas and liquid. Usability of the production devices on any ship and air-transportable construction result in additional decisive time advantages.

Title: Baking oven
Inventor: SCHNABEL WERNER ING GRAD
IPC: H05B6/80
Filed: 1984-02-07
Abstract: For baking ovens, it is known to build the box-shaped oven muffle, closable by a door, into an inherently rigid, stable frame, to which the external covering metal sheets and also if necessary an upper cooking hob are fastened. A stable, torsionally rigid construction thereby results. Such a supporting frame is however relatively costly as regards space. In order also to obtain a torsionally rigid construction for a baking oven with small external dimensions, especially in one with thermal heating elements and with a microwave device, i.e. with numerous electrical and electronic components and a ventilating device, it is proposed according to the invention to provide the box-shaped oven muffle and also, firmly connected to it, a likewise box-like cooling air channel, as the supporting part of the frameless oven housing, both of which together result in a rigid unit to which the remaining functional and housing parts are attached. <IMAGE>
