Title: Solar heat collector facade - with raisable folded blind for control of heat intake
Inventor: KOESTER HELMUT DIPL ING
IPC: F24J2/04
Filed: 1978-09-14
Abstract: Solar heat energy is used for heating or cooling a building by applying to the roof or the facade of the building, made of a heat storing material such as stone or concrete, a facing pane which is permeable to radiation. In the space between, a folded blind can be let down or folded up. The blind consists preferably of a plastic foil with an aluminium coating which reflects the heat in the DOWN-position to keep the facade or collectors on it cool, and allows them to be heated in the UP-position. The preferred materials for the permeable pane is polyester, scobalite, glass or acrylic glass. This system can be used either to improve the heating efficiency or to prevent the undesired heat intake.

Title: Adjusting mechanism using screw and follower - has screw thread flanks formed by short sections of specified roughness, determining bearing forces
Inventor: SEYBOLD ROLF PROF DR ING
IPC: F16H25/24
Filed: 1979-12-22
Abstract: The screw for controlling the movement of machine parts in either direction, by acting against a follower, acts as a nut and screw drive. The proportions of the follower are specified in relation to the diameter and clearance of the radial bearing used. The flanks of the thread (8) are formed by separate short lengths (1',1'',1''') formed by e.g. a conical grinding wheel (9). These lengths have a given relationship with the bearing shell to ensure optimum lubrication. The surface roughness of the moving parts of the nut and screw drive are also related to the height of the curved contact surface formed by these short lengths. These lengths can also be formed by cold forming or by sections of steel strips applied to the flanks.
Patent DE-2952209-A1 (DE)
Inventor: GEBHARDT AXEL DIPL PHYS
IPC: G03F7/20
Filed: 1979-12-22
Abstract: PCT No. PCT/DE80/00193 Sec. 371 Date Aug. 21, 1981 Sec. 102(e) Date Aug. 21, 1981 PCT Filed Dec. 20, 1980 PCT Pub. No. WO81/01887 PCT Pub. Date Jul. 9, 1981.The invention relates to a recording arrangement for image information in the production of printing forms. The laser light modulated with the image content is conducted through a multimode light waveguide into a recording element. There, the modulated laser light illuminates a diaphragm which is imaged onto a light-sensitive recording medium as an exposure point. A multimode light waveguide has the disadvantage that the light distribution at its exit surface is non-uniform due to the modes being formed in the light waveguide. Thus, the diaphragm is likewise non-uniformly illuminated and the exposure point exhibits an inhomogeneous light distribution, whereby the exposure on the recording medium is streaky. What is proposed is to dispose a scatter disk (6) and an additional focusing lens (13) between the exit surface (2) of the light waveguide (1) and the diaphragm (17) and to accordingly dimension the optical spacings. Homogenous diaphragm illumination and a streak-free recording are achieved by means of this feature.

Title: Intelligent teleprinter group terminal system - has group terminals interconnected by pairs of control and data lines
Inventor: FIEBIG HANS-HELMUT DIPL ING
IPC: H04L12/52
Filed: 1980-03-31
Abstract: Teleprinter stations (T1-T240) are connected via a group terminal (LC) to pairs of control buses (CB) and data communication buses (LB) each pair of which leads to another group terminal (LC1 to LCn). Each group terminal comprises three types of sub units, namely one (L3) constituting teleprinter connector modules (LAM1 - LAM240), a second (L2) consisting of several logic switching and supervisory circuits (LPM1-LPM3), and a third (L1) consisting of one control data module (LCM) which organises the sending out and receiving of channel switching data over buses (CB) and a second module (LSM) which selects the channels exclusively reserved for communication of data between previously set-up connections. There are as many supervisory circuit modules (LPM) as among the teleprinter stations connected to a given group terminal there are stations with equal data transmission rates. That is to say, each circuit group (LPM) can handle only stations having the same receiving and sending character band rate.

Title: Vegetable prod. extn. using gas in supercritical state as solvent - in successive stages with specific residence times to give continuous high throughput
Inventor: HELWIG EMMY
IPC: C11B1/00
Filed: 1980-05-02
Abstract: A method for the sepn. of mixts., such as vegetable prods., by extn., e.g. for the prodn. of vegetable oils, is based on using a gas in a super-critical state as the solvent. The gas, e.g. CO2, is introduced for a certain residence time in turn into many separate mixts. of the same kind. The final stage is a pressure release to separate the extracted substance. Four reception tanks, designed for high pressure, are fed by a common supply line through inlet valves which are opened in turn. Gas at super-critical pressure and temp. is introduced via a heat exchanger and compressor and another heat exchanger, for example to the tank through a valve. The gas is passed after a suitable retention time through each tank and finally reaches the pressure relief or segregation tank where the extracted substance is discharged through an outlet. This provides a continuous function of high throughput capacity. The extracted prod. is of good quality and the process is profitable.

Title: Angular transducer for ignition and for injection control - has inductive sensor of magnetised and non-magnetised markers
Inventor: HAUBNER GEORG
IPC: G01D5/247
Filed: 1980-05-10
Abstract: The angular transducer is esp. for controlling combustion engine ignition and fuel injection and has markers on a rotating transducer component detected by an inductive sensor (14). Practically any number of stages can be driven by a single sensor to perform different functions for different angular positions. The transducer is thus simple and economical. The transducer component carries one or more magnetised (14a) and ferromagnetic, non-magnetised markers (11 to 13). A current source (15) for the inductive sensor (14) is switched on by an evaluation circuit (19 to 23) for signals corresp. to the magnetised marker. The current source (15) is switched off by a second evaluation circuit (17,18,24 to 26) connected to the sensor and detecting one or more non-magnetised markers (11 to 13). If several non-magnetised markers are used, a counter (32) ensures that the source is switched off only when they have all passed the sensor.
