Inventor: WANDRES CLAUS DIPL ING
IPC: F04B45/04
Filed: 1979-01-30
Abstract: The membrane compressor driven by an electric motor can be used to inflate vehicle tyres, sports balls etc. Inside a metal housing (27) is a metal membrane (15) clamped between an upper flange and a top plate (26). The compression chamber (28) is above the membrane, inside the plate. This plate forms a unit containing a multi-way valve and a set of inlet and outlet channles, controlled by a disc valve (22), forming an outlet valve. An inlet valve (16) is formed by a piston (13) rotating above the membrane, at its centre. The inlet is formed by a hole at the centre of the membrane. Two outlet channels extend across the top plate, one each side of the rotary changeover device (18) at the centre.

Title: Cyanide contg. waste water detoxication - by oxidn. with hydrogen peroxide activated by bromide ion addn.
Inventor: SCHWARZER HANS
IPC: C02F1/76
Filed: 1979-04-20
Abstract: Oxidative cyanide-contg. waste water detoxication with H2O2, as oxidising agent, is activated by the presence of pref. 10-1000 mg/l bromide ion w.r.t. waste water. The Br- ions are pref. added to the waste water before H2O2 addn. The process takes place esp. at 10-90 degrees C and pH 5-12.

Abstract: Method of making chipboard permits reduced amts. of binder to be used, resulting in a stronger prod. Round timber is used, which is cut by a special machine in which the wood is held hydraulically against a cutting table, and cut along the grain. The cutter produces chips which are 0.002 mm thick, which are then dried to a humidity content of between 2 and 4 wt.%. They are then dusted with the binding medium in a drum under high pressure, and then formed into a cake which is pressed in the conventional manner.
Patent DE-2919752-A1 (DE)
Title: Pulp clarification system - by flotation of contaminants and odorants with biological sludge
IPC: C02F1/24
Filed: 1979-05-16
Abstract: Contaminants and odoriphores in pump and turbid effluents in sewage treatment installations are removed by passing the pulp through a flotation basin fr the thickening of biological sludge. The flocks of the biological sludge have strongly adsorbent properties so that the contaminants adhere to them and are raised to the surface. Even particles which are not floated just by the air bubbles are thus taken to the surface where a very greatly thickened floating layer can be removed by raking arms or worm conveyors. This offers a simple and effective way of removing contaminants and odoriphores.
Patent DE-2921063-A1 (DE)
Title: Scroll filter press for sepg. water from organic fibres - has roller rotating with scroll against cylindrical filter wall to achieve compression
Inventor: POELMA HERMANUS REGNERUS
IPC: B01D29/11
Filed: 1979-05-23
Abstract: Water is sepd. from a mixt. of a fibrous, organic solid material and water by means of an inclined screw conveyor into the lower end of which the mixt. is fed. The scroll is encased over a lower portion of its length in a filter material by means of which the free water is drained from the mix and is equipped at the upper end with a compression element which rotates with the scroll and subjects the mix to a pressure. The rotating element interrupts the scroll and presses the mix against the outer filter whilst the scroll continues to convey the material through the conveyor. The pressure element is pref. in the form of a long roll rotating about a shaft parallel to the shaft of the scroll and linked to it by means of two pairs of hinged arms and a compression spring. If the scroll is mounted on a hinged lower foot, its angle of inclination can be adjusted. The scroll/filter combination is simple and much less expensive than traditional filter press installations so that it can be used in small works or farms.

Title: Horizontally mounted water turbine - has inlet chamber and guides arranged to give radially outward flow of water through impeller
Inventor: SCHWEIGER FRANZ
IPC: F03B17/00
Filed: 1979-11-02
Abstract: The turbine is mounted horizontally and the shaft extends beyond the wheel over a water inlet chamber (1) into which the driving water flows under its static head. The chamber is alongside the turbine wheel and is filled with water under pressure. Stationary guide blades (2) in the chamber lead the water axially into the turbine blades (3) at their radially inner ends. The water flows radially outwards through the blades and is discharged after turning through 90 deg. This produces radially outward flow so that centrifugal force adds to the energy extracted from the water.

Title: Methane mfr. from biomass - in two self-contained cylindrical package units
Inventor: SAUFF HEINZ WERNER
IPC: C12M1/107
Filed: 1979-12-20
Abstract: Methane gas is produced from biomass, i.e. manure, excreta, vegetable waste and algae in a 40 ft. container with a system of tubes which includes all necessary heating equipment and is heat insulated.

Title: Braking system for trailer of vehicle - has sensor in form of moving coil detecting centrifugal force and initiating braking
Inventor: WYCHNANEK RAINER DIPL ING
IPC: B60T8/24
Filed: 1979-12-22
Abstract: The braking system has a sensor (1) producing a signal when the trailer experiences a centrifugal force.

Title: Reclining chair with adjustable footrest - has independent adjustment of footrest and backrest inclination by swivelling motion and guide rollers
Inventor: KERSTHOLT FRITZ
IPC: A47C7/50
Filed: 1980-07-23
Abstract: The easy chair has side members in the form of an inverted U which form the legs (1) and arm rests. A seat frame (2) supports the seat cushion (21) and the hinged backrest (3). A foot rest (12) is pivoted on the end of arms (8) which run between upper and lower rollers (5).

Title: Folded monopole antenna - has earthed mast and is supported by guys without insulators (NO 1.3.82)
Inventor: BRUGER PETER DIPL ING DR
IPC: H01Q9/34
Filed: 1980-08-06
Abstract: The folded monopole consists of a mast (1) which is grounded and is 290m. high for an antenna which is to be operated on a wave length of 1.271m. in free space. Looking down from above with the mast (1) as centre of a circle, the guy ropes (2-5) are distributed at right angles of 0, 120 and 240 degrees, while the cage antenna conductors are distributed at 60, 180 and 360 degrees, and fixed by guys (7) with interposed insulators (8). The antenna conductor is connected by a feed point (9) at the base of the mast. Since there are no insulators in the main guys (2-5), the mast (1) is therefore connected electrically with earth potential (10). The lack of insulators in these guys has the advantage that the danger of breakdown of insulation is avoided, and the collapse of the mast in a storm, should an insulator be destroyed.
