Title: Hydraulic valve gear for an internal combustion engine
Inventor: HENNING HERMANN DIPL ING
IPC: F01L9/11
Filed: 1988-10-01
Abstract: A hydraulic valve gear for an internal combustion engine has a working piston 5 connected to the valve 1, which piston in a cylinder 6 defines a pressure chamber 8, in which a compensating piston 9 is displaceably arranged. At the end of the closing movement of the valve 1, the working piston 5 immerses with an end section 12 in a hollow space 11 of the compensating piston 9, forming a restrictor gap, as a result of which a braking action is obtained. Hydraulic length compensation is achieved in that the compensating piston 9 in the rest position of the valve 1 and the working piston 5 is pressed by a spring 33 against a stop 14 on the working piston 5 and the thereby enlarging space 30 is filled with hydraulic fluid by way of the non-return valve 29. <IMAGE>

Title: Suppository for treating the anal canal
Inventor: BRUEHL WILHELM DR MED
IPC: A61K9/02
Filed: 1989-02-17
Abstract: This suppository has an enlarged head piece (2) at its front end and a cotton-wool or foamed stopper (4) projecting beyond the suppository surface at its rear end.

Title: Drying loose, particulate materials in closed circuit - by passing warm air through material to remove moisture, drying and recirculating while air quantity is controlled to material output
Inventor: KARLS DIETER
IPC: F26B21/12
Filed: 1989-09-08
Abstract: In a process for drying loose, particulate materials, dry warm air from a blower moves in a closed circuit through the loose damp material. The moist air is redried after leaving the material container and is reheated before being recirculated to the material container. The vol. of air supplied to the container is controlled in relation to the throughput of particulate material. Energy usage is therefore reduced and thermal shock to the material diminished. Process equipment has a sensor for determn. of material throughput which sends a signal to a controller which operates a throttle in the air supply pipe to the material container. USE/ADVANTAGE - For drying loose particulate materials, partic. heat sensitive materials. The process reacts quickly to changing parameters and therefore the material is carefully treated.
