Title: Heat pump with compressor driven by a hot-gas machine without displacer
Inventor: LANDMANN HERO DR ING
IPC: F25B27/00
Filed: 1987-10-29
Abstract: The heat pumps works, as is known, with a compressor in whose connected cooling coils, interconnected by a throttle, on the one hand cold is produced which withdraws heat from the media (e.g. water or air) fed from outside in order to release it to the house radiators via the part heated by the compressor. The compressor is driven by a hot-gas engine, through whose cold part cooling water flows and is separated from the hot part, which is heated by furnace gases (characterised thereby), and connected by the horizontal plate (20) and by the "switching cylinder" (30) which connects the force cylinder (10) alternately to the cold or hot part, the main working piston (9) of which moves the conveying piston (29) of the media-conveying installation (429) which is controlled via the impingement spaces, as in German Patent 3138683. The cooling water from the cold space (7) passes through the waste heat boiler (41) into the cooling coil (43) and releases its heat to the flowing-through media which then pass it on to the compressor-cooled cooling coil (48), around which flows the media stream. <IMAGE>
Patent DE-3737941-A1 (DE)
Title: Device for guiding bars in lathes
Inventor: EISINGER HANS
IPC: B23B13/08
Filed: 1987-11-07
Abstract: During the turning of bars which are longer than the spindle of the lathe, reducing tubes are screwed to the rear end of the spindle to reduce the vibrations of the bars. The inside diameter of the reducing tubes is slightly greater than the diameter of the bars. This requires the supply of a large number of reducing tubes and high set-up costs when changing bars of different diameter. A device is to be created which prevents these vibrations and can be adapted in a simple manner to different bar diameters. Connected to the spindle via a flange (30) is a tube (1), in the interior of which a centring device is arranged. The latter consists of several articulated rods (7) which are arranged on a circle and run in the direction of the tube axis (24) and are each mounted in a universally jointed manner at their ends in two bushes (4, 9). One bush (4) is mounted in the tube (1) in such a way as to be fixed in terms of rotation but so as to be axially displaceable, while the other bush (9) is mounted in the tube (1) in an axially fixed manner but rotatably and can be secured in the respective rotary position. If the other bush (9) is rotated, the inside diameter is reduced by the articulated rods, in the course of which the articulated rods (7) abut against the bar to be machined. <IMAGE>

Title: Device for controlling compression
Inventor: SCHRECK GERHARD
IPC: H01T13/16
Filed: 1987-12-14
Abstract: A device for controlling the compression ratio of a multi-cylinder reciprocating piston internal combustion engine is described for vehicles, in particular passenger cars. This device has an actuator piston (5) which is assigned to each cylinder (2) and is kept adjustable by an actuator drive (14) in a secondary combustion space (4), connected to the cylinder combustion space (3), as a function of the loading of the internal combustion engine. In addition, a spark plug is provided which can be adjusted with the actuator piston and has an insulator (8) which is kept gas pressure-tight with a spark plug housing and has a central electrode (11) which can be fed with ignition current. In order to achieve the best possible conduction away of heat from the base of the spark plug which is particularly highly thermally stressed, the spark plug housing of the spark plug is to be directly designed as an actuator piston with a piston collar (6) which slides in the cylindrical secondary combustion space (4) and with a piston neck (7) which engages with the actuator drive (14). <IMAGE>

Title: Process for producing thermoplastic polymers with a textured surface and thermoplastic polymers produced by an embossing roller
Inventor: KUPILLAS MAX DIPL ING
IPC: B29C59/04
Filed: 1988-02-18
Abstract: The PVC films produced by the customary process by means of an embossing roller have a surface structure on which grooved-roller transitions and smears are visible, which additionally do not clean very well and have only a low scratch resistance. Therefore, a process using an embossing roller is proposed, the surface structure of the embossing roller being produced by small, hard shaped objects being fired at the surface of the embossing roller. Random, chaotic impact by the shaped objects cause undirected indentations to be produced on the surface, and films produced by such an embossing roller are correspondingly provided with hemispherical depressions with round smooth transitions, avoiding disturbing striped patterns and allowing the textured surface of the films to be cleaned easily.

Patent DE-3823104-A1 (DE)
Title: Process and plant for treating exhausted DeNOx catalyst plates
Inventor: RANLY HANS DR RER NAT
IPC: B01J23/22
Filed: 1988-07-07
Abstract: Exhausted catalyst plates (4) contain, in part, valuable materials which at the same time cannot be disposed of entirely without problems. For this reason it is desirable to reprocess the exhausted catalyst plates to such an extent that the lowest possible amounts must be disposed of and the valuable raw materials can as far as possible be supplied for re-use. In this case it has proved to be difficult to detach the catalytically active substances from the support metal sheet. By immersing the plate catalysts in a solution which dissolves the layer on which the catalytically active substances are applied, it is possible to detach the catalytically active substances from the support metal sheet (50) and then to filter them off from the solution. Both the bare support metal sheets and the residue (36) filtered off from the solution can be supplied for re-use after a further treatment stage (40). The process and the plant are especially suitable for reprocessing exhausted DeNOx catalyst plates. <IMAGE>

Title: Method for the production of groundwood, and grinder for carrying out the method
Inventor: BARNSCHEIDT WOLFGANG DIPL ING
IPC: D21B1/24
Filed: 1988-08-04
Abstract: The production of groundwood is normally carried out by means of grinder stones (1) with the addition of spray water, the logs being ground to a ground wood suspension which is extracted from the grinder, sorted and/or refined. Independently of whether press grinders (18) or continuous grinders (17) are used, which can be designed as encapsulated pressure grinders or as grinders which operate at normal atmospheric pressure, the question of the temperature of the grinder stone surface is decisive for the quality of the groundwood produced. The temperature of the grinder stone surface is kept below the boiling point region, the temperature difference between the grinding zone and regions outside the grinding zone being held simultaneously at a value between 5 and 20 degrees.

Title: Process for the combined hydrogenation of coal and heavy oil
Inventor: WUERFEL HELMUT DR ING
IPC: C10G1/08
Filed: 1988-09-08
Abstract: In a process for the combined hydrogenation of coal and heavy oil, it is proposed to pump two separate streams of feedstock up to pressure and to heat them, one stream consisting only of heavy oil and the other stream consisting of a suspension of coal and heavy oil and to heat the heavy oil stream to a higher temperature than the suspension of coal and oil. In this way, a part of the heat required for heating the suspension can be introduced into the system by the heavy oil stream, so that smaller total heat exchange area for heating is required for the suspension itself which has a higher viscosity and a poorer heat transfer than heavy oil.

Title: Self-controlling vehicle and method for operating the same
Inventor: HATTORI AKIRA
IPC: G05D1/02
Filed: 1989-04-14
Abstract: In a method for operating a self-steering vehicle, which travels autonomously on a path network, data about a plurality of target points and a plurality of path sections are stored, the travel path being subdivided into track sections which correspond to the path sections and whose starting and ending points are defined by the target points. The form of each track section is determined on the basis of the stored data and, using the determined form of each track section, a desired travel state of the vehicle is established which forms the basis for the control of the vehicle. Furthermore, on one of the path sections a new target point is established which has the shortest distance to the starting position of the vehicle and data are generated about the new target point, including data about the travel state of the vehicle at the new target point. In a corresponding way, a new target point and associated data are also established for the final travel target of the vehicle, so that the starting position and the travel target can be selected arbitrarily in the path network.
