Patent DE-3926597-A1 (DE)
Title: Appts. to adsorb moisture, etc. from gas stream - has reserve absorbent in external store to compensate for erosion and shrinkage of absorbent
Inventor: GRAEFF RODERICH W DR ING
IPC: B01D53/26
Filed: 1989-08-11
Abstract: An outer casing has axially aligned inlet and outlet terminals for incoming and outgoing air. Moisture initially present in the air is captured by adsorbent particles, esp of silica gel or moleculer sieve, held within the  walls of a hollow entered container freely standing within the casing, and discharging dried air towards the outlet. To compensate for gradual erosion and shrinkage of absorbent during prolonged operation, the loss may be made good by reserve absorbent from an external store delivered directly to the inner container via a feeder through the outer casi casing. In a variation, gas for treatment flows horizontally through the central container, with the reserve material delivered vertically directly into that container. In either case, the reserve store is at least partly transparent to permit continuous monitoring. ADVANTAGE: Drying action is kept largely constant and enviornm-ental pollution by eroded dust is reduced.

Patent DE-4014754-A1 (DE)
Inventor: ERTL WOLFGANG
IPC: H01H13/705
Filed: 1990-05-08
Abstract: A key has a socket which opens upward into which a ram can be inserted. The ram has spring-loaded catches which engage with impact surfaces and maintain the ram in a rest position. Damping springs mounted on the ram co-operate as flexible tongues with corresponding limit stops projecting from the socket in the path of motion of the ram. When the ram is in the rest position, the damping springs are pressed against the corresponding limit stops and deformed. The deformation of the damping spring damps the lifting movement of the key ram, thereby deadening the noise of impact.
Patent DE-4016244-A1 (DE)
Title: Aeration plate for clarifier tanks, etc. - with porosity greater near its edges than at its centre, to improve mixing of bubbles and liq.
Inventor: POERSCH RUDOLF
IPC: B01F3/04
Filed: 1990-05-19
Abstract: An aeration device consists of a hollow support (1) which can be connected to an air supply and contains a porous aeration plate. The porosity of the plate (8) varies across its surface area, areas of greater porosity (14) lying beside areas of lesser porosity (13). The porosity near the centre of the plate is less than that near its perimeter. The zones of different porosity may be concentric to each other. The plate is made of a ceramic or plastic material, and the different porosities are produced by varying the grain size of the material structure. Alternatively, different porosities can be produced by covering parts of the surface of a plate of uniform structure. Bitumen, paint etc. may be used as a covering material. USE/ADVANTAGE - Used in the aeration of for example clarifier tanks. It has been found that with similar plates of uniform porosity, the rising stream of bubbles tends to cling together, thus reducing the aeration effect. By varying the porosity of the plate, the shape of the stream of bubbles rising in the tank is varied so that the mixing of the liq. with the air bubbles, and therefore the aeration effect, are intensified.

Patent DE-4108657-A1 (DE)
Inventor: STRAUB JOACHIM
IPC: F01M11/06
Filed: 1991-03-16
Abstract: A gearbox (1) for a vehicle has a housing (2) containing oil and air in which members (3, 4) move. A pump (6) supplies oil to the members (3, 4). An intake opening (7) of the pump (6) is located at the bottom of the housing (2). Despite the fluctuating oil level, the members (3, 4) always remain above and the intake opening (7) always below the oil level. To this end, a sealed container (11) with a base (12) at the height of the lowest oil level (15) (at a lowest temperature and therefore at a lowest volume of oil when the vehicle is at a standstill or moving at uniform speed straight ahead on horizontal ground) with an oil line (17) below the lowest oil level (15) with an oil exchange opening (21) at the height of the lowest oil level (15) and with an air line (29) with an air exchange opening (33) above a highest oil level (16) (at a highest temperature) is fixed inside the housing (2). At the lowest temperature the container (11) acts as a positive displacement unit to prevent the oil level from sinking too low, and as the temperature increases the container (11) acts as a reservoir to prevent the oil level from rising too high.
