Patent DE-3811532-A1 (DE)
Title: Rotary engine for drive and compressor
Inventor: BRUNS HANS-HERMANN
IPC: F02B53/08
Filed: 1988-04-06
Abstract: The overall assembly is a two-stroke heat engine owing to the compression and expansion phase produced in one rotation of the slide. Due to the good barrier function between the differential pressures a displacement effect is achieved during rotation, making the same assembly suitable for drive functions and for compression functions. Design advantages     1.) Simple construction with few moving parts.   2.) Acceleration of the masses in one direction.   3.) A thrust power of 300 degrees for each rotation of the drum. 4.) Rotating drum produces the function for barrier element and charge element and output, cooling, lubrication and flywheel. 5.) Due to the small dead space little residual gas is retained; hence good fresh gas charging. 6.) Good mixing of the charge and heat distribution in reaction and compression heat due to two assemblies. 7.) Owing to the balanced masses only one assembly with one proportionately larger design construction is necessary for a larger power demand.
Patent DE-3818580-A1 (DE)
Title: Light-liquid trap
Inventor: DIEFENBACH GUENTER
IPC: B01D17/02
Filed: 1988-06-01
Abstract: In petrol and oil traps which are provided with a float closure to shut off the clarified water discharge on reaching the highest storage quantity, the layer thickness is sensed with a probe. This gives an alarm when the maximum layer thickness is reached and the light liquid must be disposed of. If this alarm is disregarded, the float closure then closes off the discharge and a build-up arises, in the course of which the probe surfaces again out of the floating layer. In this condition the alarm can mistakenly be cancelled. The object of avoiding this impermissible condition is now achieved, in that the highest permissible build-up is scanned by a further upper feeler probe and the alarm from this feeler probe can only be acknowledged when the lower probe is also deactivated.

Filed: 1988-06-06
Abstract: Bearing for the radial and axial support of a rotor (10) with a large radial extension on a stator (1), with stabilisation of the rotor (10) about its tilting axes X, Y. To determine the tilt angle, each of the two tilting axes X, Y is assigned two clearance sensors (22, 24; 23, 25), connected to controllers (29). As a function of the output signal of the clearance sensors (22, 24; 23, 25), the controllers (29) generate control currents for control coils (17, 19; 18, 20) arranged on the stator (1) and assigned to the tilting axes X, Y, and, in conjunction with permanent magnet rings (21) arranged on the rotor (10), these exert torques on the rotor (10), thereby influencing the tilt angle. The controllers (29) have mutual coupling (in 31) and this cancels out the coupling of the tilting axes X, Y caused by the gyro effects. The controllers (29) are PD controllers. In one embodiment of the coupling (31), its gain Vr is varied in a manner proportional to the square of the speed n of the rotor (10) and its time constant Tr is varied in inverse proportion to the speed n of the rotor (10). The central bearing for the radial movements in the X/Y direction is either passive, incorporating a permanent magnet, or active, incorporating an electromagnet. In the latter case, the radial position controllers are PD controllers, the parameters of which can be switched between a "soft" and a "hard" mode of operation in order ...
