Patent DE-4129608-A1 (DE)
Title: Sludge dryer shell control - has indirect dryer with simulated feed action on a fault to maintain action of condenser and boiler
Inventor: BELTING KARL-WILHEM DIPL ING
IPC: B01D53/00
Filed: 1991-09-06
Abstract: The thermal process to remove smell from the exhaust gas and/or vapours from a sludge dryer, which is heated indirectly and under a light underpressure, extracts them by suction to be passed to a condenser together with a given volume of air drawn into the system. The part which can be condensed is passed to further waste management of the sewage purificn. plant and the part of the vapour which cannot be condensed is passed for after burning in a boiler. The boiler steam is reduced to atmospheric pressure in the event of shifting load and/or irregular behaviour and an additional water flow is introduced for condensation and the steam is directed to the condenser in a bypass round the dryer. When the fault has been corrected, the steam feed from the boiler is restored to the dryer. ADVANTAGE - The operation gives a simulated feed action in the event of a shift from normal working, so that the system functions normally, reduces and contains smell emissions, without the need for e.g. an active carbon filter which has to be exchanged.
Patent DE-4130620-A1 (DE)
Title: Bending process for shaping flat honeycomb layer - includes vacuum holding film-covered layer on flat bendable plate and second film covering over first, aids vacuum drawing into curved cavity
Inventor: EBERLE WALTER
IPC: B29D24/00
Filed: 1991-09-14
Abstract: In process for bending flat components with honeycomb structure, the component is initially positioned on flat deformable supporting plate. After covering the component with air-tight film, vacuum is applied to the enclosed vol. to draw the film tightly onto the component surface. The supporting plate together with the component to be shaped is located above the tool cavity and covered in second air-tight film. Further application of vacuum pressure to the area underneath the films draws the component and supporting plate onto the profiled cavity surface. The process uses a heat curable plastic honeycomb which is formed in the uncured state and then heated to rigify the structure in profiled condition. USE/ADVANTAGE - The process facilitates bending of honeycomb cores for composite sandwich structures and eliminates the need for special thermoplastic covering layer used to prevent damage to the structure during forming.

Title: Vacuum motor without combustion - has vacuum produced artificially in cylinder chamber and working with atmospheric air to drive piston
Inventor: SELIG PETER
IPC: F01B29/02
Filed: 1991-09-23
Abstract: A piston (3) runs in the cylinder (1) and is connected to a connecting rod (4) joined in turn to a centrifugal mass, or there are several pistons in several cylinders which are connected to a centrifugal mass with connecting rods via a crankshaft (5). The principle of the motor is that the atmospheric air pressure is forced to press on the piston(s) in the cylinder(s) under vacuum. The pressure balance for the backward run of the piston by the centrifugal mass occurs via air inlet slot slots or valves. USE/ADVANTAGE - A motor without combustion or explosion which is driven by vacuum working in conjunction with atmospheric air pressure.

Title: Charge drainage prevention for automobile battery - disconnecting electrical leads automatically when engine is cut out but allowing manual re-connection
IPC: H02J7/00
Filed: 1991-11-12

Title: Multicoloured crimped yarn process - uses coloured multifilament yarn running parallel at various stages of production to avoid colour mixing
Inventor: GERHARDS KLAUS
IPC: D02G1/12
Filed: 1992-02-01
Abstract: Prodn. of multi-coloured crimped yarn from at least two different coloured multifilament synthetic yarns so that the filaments resemble and are parallel to each other, comprises spinning, treating, and assembling each colour separately, false twist, then drawing in parallel, texturising in hot air, crimping cooling and then winding on a reel. Pref. polymer melt is forced through a spinnerette for each colour. The yarn is then cooled and taken through the liquid treatment area. The filaments are assembled in parallel and taken into the false-twist airjets, each colour separately, and with very little twist. The several colours are then deflected into a draw roll zone for molecular orientation. The roll is heated. The texturiser is also provided with compressed air which passes through the heater. The yarn is then compressed into the stuffer box with air in the sides so that the compression is self regulating. The cooling drum is perforated to allow air passage, and then the yarn is passed through an entanglement jet before winding on the creel. The drive speeds at the various stages are regulated to enable drawing to take place etc. USE/ADVANTAGE - The yarn is multi-coloured, without being a mixt. of colours.

Title: Method and devices for multiplying brake forces
Inventor: BROICHER HERIBERT F DR ING
IPC: B66D5/10
Filed: 1993-02-18
Abstract: Friction brakes in conjunction with motor-operated brake boosters are the state of the art in the car and lifting gear industries. The technical object of the invention is to use the internal forces occurring when moving masses are braked for brake boosting. The subdivision of a brake system into moving and fixed brake devices, acting on only one first moving brake device with an external force and connecting the moving brake device to the fixed brake device in a mechanical or hydraulic way permits the force which is opposed to each braking force to be used to increase the overall braking force. The method for multiplying brake forces can be applied in various devices of disc brakes, belt brakes and drum brakes. It is particularly advantageous to use the invention in winders and hoisting machinery, in multi-axle lorries and trailers and also in multi-axle railway waggons. <IMAGE>
