Patent DE-3714791-A1 (DE)
Title: Slide piston rotary compressor (piston turbine)
Inventor: WUERTH GUSTAV DR
IPC: F04C18/344
Filed: 1987-03-19
Abstract: The slide piston rotary compressor (piston turbine) consists of a four-cornered, circular compression chamber, in which the slide piston rotates. The slide piston must seal the two vertical and the two horizontal sealing surfaces or slideways. The two vertical sealing surfaces run parallel to one another, but at an angle to the double partition that rotates with the piston, and also has sealing surfaces, on both sides. The partition divides the compression chamber into two compression chambers that are equal-sized, but offset by 180@. Between the intake and outlet, the oblique, vertical sealing surfaces touch the partition via a sealing strip that can be overrun by the sealing heads of the piston. The piston is located in a guideway that rotates with the partition so that it can move to either side. It is guided by the sealing surfaces in so doing. When the piston rotates, compression chambers are thus created to the right and to the left of the partition, with suction after the piston and compression ahead of the piston. If used as a piston combustion turbine, the compressed air (gas) is pressed into an antechamber, combustion chamber or the like lying outside the casing and provided with sealing members at both ends. In this antechamber, the gas mixture is ignited or the fuel is injected. The ... Original abstract incomplete.

Title: Method of reworking rotating components full of wear marks
Inventor: HAEFNER REINHARD DIPL ING
IPC: B24B5/42
Filed: 1987-05-14
Abstract: In a method of reworking rotating components full of wear marks, in particular crankshafts and engine bearing journals exhibiting ridge wear, a machining shell is inserted instead of the bearing shell. The machining-shell inner surface facing the component to be reworked has areas covered with an abrasive material. By means of an external drive unit, the component is set in rotation until the desired removal of the wear marks is achieved; then the machining shell is replaced again by a bearing shell. The abrasive residues accumulating during the machining are caught and removed from the bearing area.

Title: Device and process for applying adhesive
Inventor: HAARHAUS MARKUS DR
IPC: B05C1/08
Filed: 1987-05-16
Abstract: In a device for applying adhesive onto a moving material web (6) and for severing a material blank in each case from the material web, a roll (2) with a severing device (9) is provided. The roll receives adhesive (12) from an adhesive applicator device (4) and, during the severing operation, transfers it to the material web (6). This permits an accurate allocation of the adhesive application to the severing line. According to the process, the transfer of the adhesive to the material web and the severing through of the latter take place in one operation. <IMAGE>

Patent DE-3737125-A1 (DE)
Title: Positive displacement machine
Inventor: STELLER DETLEF
IPC: F01C11/00
Filed: 1987-11-02
Abstract: Positive displacement machines as internal combustion engines, comprising the compressor (1), the combustion chamber (9), the engine (2) and a variable-speed drive (13), inserted between compressor and engine, designed on a simple operating principle so that it can be used in place of piston engines or of gas turbines. The efficiency of the machine is greater than that of piston engines and of turbines due to pulsed combustion and also to the fact that no balancing of masses is necessary on the moving parts. The operating principle is characterised in that a number of spherical cup rings (3) are inserted into one another, that, together with these, spherical cone-shaped, undulatory, opposing working chambers (8) are formed by a helical shaft (4), the volume of which chambers varies, migrating inwards or outwards with the rotation of the shaft. The spherical cup rings perform a tumbling movement. The shaft has a lefthand thread on one side and righthand thread on the opposite side. Sealing of the working chambers is achieved by sealing rings (7) in the spherical cups and by engagement in toothing-like depressions (5) of the housing (6). The pulsed combustion in the combustion chamber with its ignition device (12) and the injection nozzle (11) allows the temperature of all components to be controlled. The arrangement of the variable-speed drive between compressor and engine permits control of the combustion chamber pressure and a speed control ... Original abstract incomplete. <IMAGE>

Title: Circuit arrangement for limiting an operating voltage for electrical consumers, particularly in motor vehicles
Inventor: GLEHR MANFRED
IPC: G05F1/575
Filed: 1987-12-01
Abstract: The circuit arrangement (S) has a series transistor (1), a regulator (4), an input (2), to which the operating voltage (UB) is fed, and an output (3) having an output voltage (UA), which is present at an electronic consumer (5). As long as the operating voltage (UB) is between a permissible limiting value and a threshold value, the regulator (4) drives the series transistor (1) into the saturation region and the output voltage (UA) is approximately equal to the operating voltage (UB). On the other hand, the output voltage (UA) is limited to the limiting value if the operating voltage (UB) rises above the limiting value. <IMAGE>
