Patent DE-4003566-A1 (DE)
Title: Multi-cylinder diesel engine with supercharger - which supplies only some of the cylinders when engine is started
Inventor: LEGAT REINHARD
IPC: F02B3/06
Filed: 1990-02-06
Abstract: The multi-cylinder Diesel engine is started and operates during the warming up period by supplying some but not all, cylinders with compressed air from the supercharger. The ignition temp. of the fuel can thus be achieved with a lower engine compression ratio. When the engine has reached its normal operating temp. compressed air is supplied to the remaining cylinders. By reducing the compression ratio of the cylinders by supplying pre-compressed air the peak cylinder pressure is reduced and this enables the weight of the engine to be reduced.

Title: Radar responsive reflector - for vehicles based on reflecting and non-reflecting pattern of stripes of specified lacquer
Inventor: SARIDAKIS NIKOLAUS DIPL PHYS
IPC: H01Q15/14
Filed: 1990-08-22
Abstract: Checks of the distance from a moving vehicle to the vehicle in front by radar are often falsified by objects near the traffic lines which also reflect the radiation and do not identify that vehicle. It is therefore suggested to replace the reflector by a system of reflecting and non-reflecting strips of bodywork lacquer, arranged in a sequence which is significant for the vehicle concerned. This lacquer can be based on rhodopsin. ADVANTAGE - This type of reflector permits a definite identification of the vehicle.
Patent DE-4038109-A1 (DE)
Inventor: HOPP WERNER DR RER NAT
IPC: B01J20/32
Filed: 1990-11-29
Abstract: The invention relates to a process for making mouldings with a porous surface and close surface pore radius distribution and the use of these mouldings as bearers for securing or immobilising indicators, catalysts, a bio-mass or parts of the bio-mass. The mouldings are coated with small, uniform particles with a narrow particle size distribution of a material capable of agglomeration without the application of pressure or the addition of a binder and at temperatures below 120  DEG C so that the interstices between the small uniform particles on the surface of the mouldings form pores with a close pore radius distribution. The shape and size of the pore radii are determined by the shape and size of the small uniform particles and the pore radius distribution is determined by the particle size distribution.

Patent DE-4101070-A1 (DE)
IPC: C11D1/14
Filed: 1991-01-16
Abstract: The surfactant ingredient in detergent powders nowadays is mainly composed of petrochemical-based surfactants; the biodegradability and the ecotoxicity usually do not correspond to those surfactants based on natural raw materials. A mixture for detergent powders which contains a very high content of surfactants from renewable raw materials is therefore proposed; the washing results and biodegradability are surprising and outstanding. The mixture according to the invention is composed of alkyl polyglycosides with degrees of glycosidation of </= 1.4 as well as anionic surfactant, fatty alcohol oxethylates and soap.

Title: Warp sizing installation - has beams supplying sheet of warp through reed to sizing vat and oscillation damper on input from each supply beam
Inventor: BUSCH WILHELM
IPC: D02H5/02
Filed: 1991-05-17
Abstract: A warp sizing installation has beams supplying a sheet of warp through a reed to a sizing vat. The yarn supply from each beam is tensioned through an oscillation damper. Pref. yarn selection from the supply beam is reversed around a roller (4) which is supported at the axle in a bracket (11) having a central pivot (13). This is balanced on the second bracket fixed to the frame (12). At one end (16) of the bracket arm (11) a spring (17) is stretched to the base (12). At the other end (14) a cylinder is connected. The cylinder (18) has a piston (19) with an open valve (21) and is filled with a high viscosity fluid (20), controlled at the regulator (22), so that a balance is obtained with the spring, to eradicate the inbalance and frequency oscillation which at certain stages of high speed winding may reach a pitch of resonance in the warp threads. ADVANTAGE - The supply of yarn from each beam is prevented from unwinding excessively at high speeds. Vibration and lack of stability would cause yarn breakages at the reed.
