Patent DE-3835414-A1 (DE)
Title: Ejector force control of a die cushion for presses
Inventor: GEIST GREGOR DIPL ING
IPC: B21D24/14
Filed: 1988-10-18
Abstract: The aim is a pneumatic die cushion which enables, irrespective of the method of control, adjustment of the ejecting force from zero up to the size of the counter-holding force, in the case of a conventional design of the cushion plate with the path-dependent stop damping. The object consists in resolving the cushion force during ejection into two components which act independently of one another, the larger component of which can optionally become inoperative as ejecting force. According to the invention, this is achieved in that the die-cushion space is divided into two separate pneumatic spaces (19, 20) by a dividing wall (17), the oil space between the pressure piston (6) and the differential piston (5) is divided into two separate oil spaces (21, 22) by a dividing wall (18), a piston (4) is fixedly connected to the piston rod (3) in the upper pneuematic space as upper delimitation thereof, the pneumatic spaces (19, 20) are assigned pressure-reducing valves (7, 8) and between the two a non-return valve (9) is seated, and the differential piston (5) can be included, by controlling the flow of oil into the oil spaces via independently controllable throttle valves (12, 13), for varying the ejector force. <IMAGE>

Patent DE-3838410-A1 (DE)
Title: Shut-off valve for vacuum pumps
Inventor: ENGMANN HUBERT DIPL ING
IPC: F16K31/122
Filed: 1988-11-12
Abstract: The invention relates to a shut-off valve (check valve) for oil-sealed vacuum pumps. It is accommodated in a valve housing (valve body) which is attached to the pump housing and which, by means of a fixed partition, is divided into a valve chamber, which accommodates the valve disc, the valve tappet and a pressure spring, and a swept chamber which contains the tappet, the piston and a pressure spring (compression spring). For the purpose of the passage of the tappet, the partition has a bore slide fit. The tappet is provided with a venting duct which is composed of a radial and an axial section, the latter at its front end being fitted with a nozzle. On that section of the tappet which is situated in the valve chamber, a thrust collar is permanently fixed at a distance from the partition which equals the travel. Used as the sealing element there is a seal ring bearing on the thrust collar. Next to the partition, a second oil draining hole fitted with a nozzle runs into the swept chamber. The shut-off valve does not have any dynamically stressed sealing elements. As a result, its susceptibility (proneness) to faults is low. It closes very rapidly, admitting little air, as a result of which a better vacuum is ensured.

Patent DE-3906141-A1 (DE)
Title: Hydraulic motor-vehicle brake system with an anti-lock control device
Inventor: GABRISCH ROMAN DIPL ING
IPC: B60T8/40
Filed: 1989-02-28
Abstract: In a known hydraulic brake system with an anti-lock control device, a controllable hydraulic pump connected to the wheel brake cylinders is provided. When the anti-lock control device is inactive, this pump assumes the function of brake boosting and, when the anti-lock control device is active, it assumes the function of a brake-pressure modulator. For this purpose, its output pressure is controlled in the first case by the output pressure of the master brake cylinder and, in the second case, by a control signal output by the anti-lock control device. In the new hydraulic brake system, a hydraulic pump is likewise to assume both the function of brake boosting and that of pressure modulation but the outlay for this, particularly that on control, is to remain relatively low. The controllable hydraulic pump, which can be switched on automatically when the service brake is operated, is designed as a rotary piston pump that can be controlled not only as regards its delivery rate but also as regards the direction of delivery and is in each case arranged in the brake line leading from the master brake cylinder to the wheel brake cylinders. During normal braking phases, its direction of delivery is set in the direction of the wheel brake cylinders and when the anti-lock control device is exercising control, is set in the direction of the master brake cylinder for pressure reduction. <IMAGE>

Patent DE-3924908-A1 (DE)
Title: Freezing dried carbon di:oxide from fossil fuel combustion - for sinking as dry ice into deep sea to counter greenhouse effect
Inventor: KUENSTLE KONRAD DIPL ING
IPC: C01B32/50
Filed: 1989-07-27
Abstract: Given that the 'greenhouse effect' derives largely from the CO2 mitted on combustion of fossil fuels, the exhaust gases from plant burning such fuel are cooled to condense the water content, while the CO2 is coded to form 'dry ice', which with density over 1.1 kg/litre is disposed off by sinking in deep oceanic water. To produce N2-free exhaust gases, combustion takes  place with O2 and the processed gases are recycled to reduce combustion zone flame temp. Only the surplus portion of the recycled gases is then treated to produce the 'dry ice'. An air fractionator produces N2 and O2 for use as cooling medium to pre-cool the CO2 for 'dry ice' mfr. Remaining plant components include a turbinee, heat exchangers and a gas washer. ADVANTAGE - Since deep water only replaces surface sea water very slowly, CO2 remains lost to the atmos.
