Patent DE-3420520-A1 (DE)
Title: Positive-displacement pump having approximately radially arranged pistons
Inventor: DWORAK WILHELM
IPC: F04B1/04
Filed: 1984-06-01
Abstract: The pistons (16, 17) of the positive-displacement pump constructed as a radial piston pump are driven by an eccentric disposed on a drive shaft (20) and designed as a ring (19). The ring is fixed on the drive shaft in a positively locking and frictional manner by means of two needles (21, 22) pressed in between the shaft and the inner side of the ring. In this way, a cheap eccentric drive using simple stock components is obtained. The pistons (16, 17) are held together in a positively locking manner by means of a coupling member (24) which is designed as a punched sheet metal part and which has a slit (25) through which the drive shaft (20) passes. Thus it is possible to dispense with pressure springs for the pistons (16, 17).

Patent DE-3519186-A1 (DE)
Title: Improvement to the rotary engine (Wankel engine)
Inventor: PAPPERT JOSEF
IPC: F02B55/00
Filed: 1985-05-29
Abstract: A further development of the patent application P3447321.1. In this application the sealing element is only under spring tension. It may happen, due to the centrifugal force, that the sealing element lifts off from the cylinder barrel. The roller tappet shell is now bedded in a recess with rotatable bearing of the sealing element, which slides on the cylinder wall. The sealing element is composed of ceramic (aluminium titanate + aluminium oxide fibres). A cam, the opposite end of which slides on the control cam and thus holds the sealing element on the slideway, engages in the tappet. Due to the centre of rotation of the sealing element in its recess very close to the slideway, wear is reduced. Lubricating oil is supplied to the sealing elements due to the periodic movement of the plugs. The latter have small oil pockets. At the outer dead-centre position the oil pockets are discharged up to the seal surfaces and the cylinder barrel. The circumferential surface of the piston (diesel engine) is lined with ceramic providing good insulation. Due to these measures the combustion temperatures are increased, thereby resulting in increased power and reduced fuel consumption and a reduction of the amount of pollutant emissions in the exhaust gases.

Patent DE-3546174-A1 (DE)
Title: Apparatus for keeping sewage away from a receiving watercourse
Inventor: STAHN ROLF
IPC: E03F5/10
Filed: 1985-09-27
Abstract: The apparatus presented here for keeping sewage away from a receiving watercourse is to be used predominantly in the area of town drainage.   In particular in the case of combined sewers, rain can lead to sewer overloading, with the result that possible ways of relieving the sewers have to be provided. If receiving watercourses are provided, excess water is separated off into the receiving watercourses. This can involve high degrees of contamination of bodies of water. In order to prevent this adverse loading of bodies of water, there is to be arranged, in the receiving watercourse, a slack collecting tank, comprising a suitably shaped sheet which is suspended on a floating-body frame designed in a movable manner. As soon as sewage is channelled between the sheet a slight excess pressure in the water arises with respect to the water level in the receiving watercourse, said excess pressure resulting in the sheet drifting, while carrying the floating body along with it. If, after the occurrence of rain, sewage is guided out of the tank back into the sewer, the water-pressure conditions are reversed and sheet and floating body revert back into the initial position.
