Title: Solar photoelectric conversion unit - uses condensation of liq. heat carrier vapours on walls of reservoir to cool light converter immersed in carrier
Inventor: VASILININA OLGA VASILJEVNA
IPC: F24S10/95
Filed: 1979-04-27
Abstract: The solar photoelectric conversion appts. comprises a light converter immersed in a transparent liquid heat carrier which occupies the lower part of the cavity of a hollow hermetically sealed reservoir. The appts. also includes a solar radiation concentrator inserted in a beam of a solar radiation incident on an active surface of the light converter.

Title: Torpedo automatic target searching control - uses acoustic characteristics of wake generated behind target vessel
IPC: F41G7/22
Filed: 1979-11-29
Abstract: The control uses the physical characteristics of the wake behind the target. The side limits of the wake are detected and are used in a given programme, e.g. effected via a microprocessor to estimate the required strike path. Pref. the target searching control uses the differing acoustic characteristics of the wake water due to the higher content of bubbles, detected via the onboard sonar system. The sonar information is fed to a microprocessor effecting an initial programme for directing the torpedo into the wake and a subsequent programme causing it to follow the target. The control system is designed to prevent the torpedo turning towards a buoy close to the target vessel.

Patent DE-3010191-A1 (DE)
Title: Diesel motor powered electric drive for aerial ropeway - has braking system and antiparallel diodes with switches in armature circuit
Inventor: RICHELMANN CARL DIPL ING
IPC: H02P3/06
Filed: 1980-03-17
Abstract: The electric drive uses a diesel engine to drive a d.c. generator, which powers a d.c. motor which can rotate in either direction. In the armature circuit for both machines is a variable resistance for a braking system. Connected across the armature circuit are two antiparallel diodes, each in series with a switch. In series with the variable resistance is a control circuit so that the braking resistance is varied independently of the nominal speed of the d.c. motor. The generator is controlled by an applied voltage so that the load fed back to it during braking is maintained within a predetermined limit. Both switches are operated according to the direction of rotation, i.e. one is closed for each direction so that its diode is in the blocking direction for the armature current flow.

Filed: 1980-04-03
Abstract: There is provided a process for the adsorption and catalytic decomposition of foul-smelling intestinal gases, particularly mercaptans, wherein the intestinal gases are passed through a highly specific adsorbent which, out of a mixture of water vapor, methanol, carbon monoxide and carbon dioxide and various sulfur-containing gases, particularly mercaptan-containing gases, catalytically decomposes and adsorbs only the sulfur and mercaptan compounds and optionally desorbs the non-smelling fractions. An absorbent for use in the method is characterized in that it contains an inert, highly porous solid having a specific surface according to BET of from 900 to 1800 m2/g or pyrogenic silicon dioxide having a surface of from 50 to 500 m2/g, the specific surfaces having been determined by argon adsorption at -196 DEG  C., which are covered over their surface with from 0.1 to 5% by weight of aluminium, zinc, chromium or iron, based on the weight of the solid having a specific surface of 1000 m2/g, or a mixture of metal-coated, inert highly-porous solids of this type.
Patent DE-3013491-A1 (DE)
Title: Reversing gear for twin screw extruder - provides same rotational direction for both screws when fitted but opposite directions when removed
Inventor: COLLIN HEINRICH DR ING
IPC: B29C48/40
Filed: 1980-04-08
Abstract: A reversing gear for a double-screw extruder or double-shaft kneading unit comprises a drive unit for oppositely rotating screws which can be interchanged. The reversing gear (10) contains a first continuous shaft (12) connected to a take-off shaft (22) of the drive unit (23) and directly driving, at its opposite end, a screw (25); this driveshaft (12) also carries a pinion (15). A second drive shaft (13) drives a second screw (34) and also carries a take-off pinion (17); this take-off pinion is connected via a reversing pinion (26) with the drive pinion (15) on the first shaft. The second drive shaft (13) is connected to a second take- off shaft (24) of the drive unit viaan axial thrust bearing (27). Used to enable a two-screw extruder or kneader to be operated either with the same directions of rotation of both screws or with opposite rotation. When the gear box as shown is fitted, the drive passes to the gear box only through the take-off shaft (22), since the thrust bearing (27) permits the shaft (13) to rotate in the same direction as the shaft (12) due to the meshing of the intermediate pinion (16) with the other two pinions. Thus the two screws (25,34) revolve in the same direction. To reverse direction, the gear box is simply taken out and the two screws are directly coupled to the take-off shafts (22,24) of the drive unit, which revolve in opposite directions.

Title: Two part light alloy wheel - has rolled rim with horizontal flange to weld onto pressed wheel disc
IPC: B60B3/06
Filed: 1980-05-08
Abstract: The vehicle wheel has the wheel rim profile rolled and the centre disc pressed, using different materials. The wheel rim has an outer flange (10) running nearly horizontal and butt welded onto a similar flange at the outer edge of the wheel disc. This provides max. strength and a simple weld process. The weld can be a friction type process. The wheel rim flange has a weakened section (10) to absorb stresses during running and enable thinner metal to be used. The weld is under the tyre bead support and can be protected by an overlapping lip on one part of the flange.
Patent DE-3020125-A1 (DE)
Title: PRoducing colour transparency from colour master - using photoelectric particles in dispersion between colour raster electrodes
Inventor: MIR JOSE MANUEL
IPC: G03G17/04
Filed: 1980-05-27
Abstract: A colour transparency is prepared from a colour master with photo-electric particles of neutral density in a dispersion between two electrodes. One electrode (11) has a colour raster and the other electrode is plain. Selective exposure to colour images provides a pattern of particles under the colour raster, which is fixed thermally for projection. The process provides a rapid colour transparency with a high resolution, using a fine spacing raster. The dispersion is charged to move the particles under the raster prior to exposure. The process provides positive slides from positive masters. For positive slides from negative masters a filter layer is interposed between the transparent electrodes.
