Patent DE-4010206-A1 (DE)
Title: Wankel type rotary engine - operates on Stirling cycle with heated and cooled casing portions
Inventor: WUNSCHIK HERBERT
IPC: F01C1/22
Filed: 1990-03-30
Abstract: The rotary piston engine is mechanically similar to the Wankel engine but operates on the Stirling cycle. The engine has a rotor with a cross-section formed by an equilateral triangle  with rounded corners. The rotor operates in a two-lobed housing formed by two intersecting cylinders. Cold air flows into the housing through the inlet port. The air is compressed by the rotation of the rotor and is delivered to the recuperator. The heated air returns from the recuperator and receives additional heat before entering the housing and driving the piston. The air then flows out of the housing to the recuperator where it heats the comoressed cold air. USE - Stirling cycle engine using Wankel-type rotating parts.

Title: Moulding machine - places ground vegetable matter in mould boxes displaced by 120 degrees to be wetted and vacuum compressed before firing in drying kiln
Inventor: WEGENER EBERHARD DR ING
IPC: A01G5/04
Filed: 1990-12-12
Abstract: To produce shaped bodies from raw vegetable materials, the material is progressively reduced to give particles of max. 2 mm, in a suitable mixture of materials to be used. The dry material is placed in moulds, which are closed by a fine mesh wire sieve. Water is applied to wet the material in the moulds, until saturated, and surplus water is removed by vacuum which also gives a hardening and initial drying action. The moulds are emptied by a slight overpressure. The damp moulded bodies are dried in a counter current tunnel kiln with an initial temp. of about 350 deg.C to dry the surface areas followed by temps. of 270-170 deg.C to dry the interiors. USE/ADVANTAGE - The moulded bodies are used for floral decorations, such as crosses, wreaths, or floral cushions, and can also be used in construction as dampening and insulation plates. The shaped materials are produced cost-effectively, without requiring impregnation which would affect the environment. The mfg. also cuts down on working time and the consumption of raw materials.

Patent DE-4221851-A1 (DE)
Inventor: ROTHHARDT MANFRED
IPC: G01B9/02
Filed: 1992-07-03
Abstract: In a laser interferometric measurement system for a plurality of measuring stations, in which each measuring station is assigned an interferometer (22, 26, 27), and which is preferably used as a multiple-measuring or multi-coordinate measuring device for the purpose of measuring lengths, according to the invention an interferometer (22) of at least one measuring station has a pair of reference reflectors (24, 25) having a fixed, defined spacing relative to one another. In each interferometer (22, 26, 27), beams which are incident as mutually equal pairs and whose frequencies differ from one another have source locations for generating component beams which are assigned to one another in conjunction with a direction of propagation which is the same at least in sections, and of which, each component beam of the one frequency has, after it has traversed an interferometer arm, a common beam path with the assigned component beam of the other frequency so as to produce interference. All the interference signals are measured and evaluated simultaneously. The invention can be used to construct a measurement system having a plurality of stations from compact interferometers with comparatively small dimensions, in which the interference (noise) quantities, such as change in the refractive index of the measurement medium and frequency fluctuations in the laser light source, have as little effect as possible on the measurement result obtained. <IMAGE>
