Title: Positive-displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C1/02
Filed: 1988-04-28
Abstract: What is described is a positive-displacement machine for compressible media, which possesses a divided housing, the housing halves of which each have at least one positive-displacement chamber (2, 3) designed in the manner of a spiral slot, and a disc-shaped rotor (18) which is driven eccentrically by a driveshaft and which has, on each of the two end faces, at least one positive-displacement body engaging into a respective positive-displacement chamber and designed as a spiral strip or rib. The radially inner ends of the positive-displacement chambers (2, 3) of the two housing halves are connected to one another via passage orifices (19) made on the disc-shaped rotor (18), and orifices for connecting the radially inner ends of the positive-displacement chambers to a connection piece guiding the compressible medium are provided only in one housing half. In order to achieve a reduction in the flow losses in that housing half which does not have the connection piece, the guide devices (10, 12) for deflecting the compressible working medium out of an essentially spiral circumferential flow into an axial flow passing through the passage orifices (19) on the rotor (18) are to be provided in the region of the radially inner ends of the positive-displacement chambers (2, 3).

Title: Oscillating-piston engine
Inventor: HAUCK GEORG PROF DIPL ING
IPC: F02B3/06
Filed: 1989-01-09
Abstract: The prior art has disclosed working methods which work with spatially predetermined compression spaces and operate by the spark-ignition or diesel process. Alternatives and suggestions for new methods are not known. The object of the invention is to employ new assumptions regarding combustion, new means of obtaining work and new means of effecting an exhaust and refill. The object is achieved by forming compression, combustion, expansion and gas exchange spaces by means of a pair of pistons oscillating in opposite directions on a circular path in a casing. In this arrangement, control of the gas exchange is effected by means of ports in the oscillating-piston discs. Extraction of the mechanical energy is accomplished, when there is an excess, by means of clamping rings situated on the oscillating-piston discs. The oscillating-piston engine makes it possible to convert the energy in fuel to mechanical energy by means of a pair of pistons oscillating in opposite directions on a circular path in a casing. The operating method is shown in the drawing, in which 1. is an oscillating piston with an inlet port e and 2. is an oscillating piston with an outlet port a. <IMAGE>

Title: Annular radiator arrangement in a motor vehicle
Inventor: HERRMANN PETER
IPC: B60K11/04
Filed: 1989-04-01
Abstract: A motor vehicle is provided in its front area with an annular radiator, which is surrounded by an air guide housing. The air guide housing has downwardly and/or upwardly directed outlet orifices, which deflect the radiator outlet air counter to the vehicle's direction of travel. The outlet orifices open on the outer skin of the vehicle in the area of a negative pressure created by movement of the vehicle. For this purpose a spoiler is arranged on the vehicle surface in front of the outlet orifices. In addition the air guide housing has a spiral cross-section in order to generate a negative pressure area on the leading radiator outlet air side. Alternatively diffuser-shaped air baffle plates are provided inside the air guide housing. These measures lead to a uniform through-flow over the depth of the annular radiator.

Abstract: Long elastic strips are produced by casting a  cylindrical-section with polyurethane elastomer on at least the outside surface and turning this into a continuous article 1 to 5 mm across and preferably a square section 2 x 2 mm. A hot-pour prepolymer with cross-linking agent for curing at 90 deg.C is cast into a cylindrical mould with vertical axis containing a steel 200 mm dia. core at the centre, so as to produce an elastomer moulding with 500 mm o.d. and length 500-1,000 mm.  After curing this and then post-curing it its steel core is mounted in a lathe. Using a high speed steel cutter it is turned into 2 x 2 mm strip 1,000 mm long from a first layer and, using a feed rate of 2 mm per turn, a length of 750 meters. The products can make polyurethane strips 50-100 m long which are stranded regularly into a belt of high mechanical strength and an extension 7 times its length. ADVANTAGE - The method is an inexpensive, simple, and technologically satisfactory way of producing elastic lengths of suitable dimensions for making polyurethane elastomer endless belts.
