Title: Hot-air exhaust gas cleaner for internal combustion engine - has control unit adjusting alternator output and controlling flow of air pumped through heater into catalytic converter
Inventor: HOSOYA YASUHIKO
IPC: F01N3/20
Filed: 1993-07-21
Abstract: The engine (1A) draws air through a filter (4A) in proportion to the throttle opening (5A), and the combustion prods. are expelled through an exhaust pipe (6A) and catalytic converter (7A). Until the coolant has attained a preset temp. the control unit (22A) allows a pump (21A) to drive air through an open valve (10A), a non-return valve (11A) and an electric heater (12A) into the exhaust pipe. The idling speed controller is activated to give a high speed while the warm-up is in progress, and the alternator is driven to supply more power for the heater. ADVANTAGE - Exhaust catalytic converter is warmed-up rapidly after starting, without excessive consumption of energy.
Patent DE-4325806-A1 (DE)
Title: Floating barrier which adsorbs oil e.g. on surface of water
Inventor: SCHIWEK HELMUT
IPC: B63B25/08
Filed: 1993-07-31
Abstract: An oil absorber, and particularly one in the form of a floating barrier to confine end, at the same time, take up oil and similar substances from the surface of water, consists of inorganic fibres coated to render it hydrophobic e.g. with a silicone and also with a binder which does not react with oil; the barrier formed has a cellular structure, in which one cell is coated with the hydrophobic non-reacting binder and another cell is filled with hydrophilic glass fibre. The glass fibres are coated with an epoxy and/or methylene or polyester resin, hardener, methylpolysiloxane or siliconmethyl resin, and a dust-laying (hydrophobic) binder, alternatively with an epoxy and/or methylone or polyester resin, hardener and dust-laying hydrophilic binder which has been already blended into an emulsion or is sprayed on to the fibres as its individual components. The materials used can also include starch.The cross-section of a barrier made, e.g. to surround a ship which is leak-oil, shows that it is in cells, of which the larger (9) is filled with the glass fibre mat (11). These fibres are coated as specified so that they do not absorb water but do take up and hold e.g. oil. The barrier thus both confines oil and also absorbs it. The smaller cell (10) is filled with non-hydrophobic fibre mat (12). The shape of this smaller cell (10) makes it difficult fro oil to pass underneath it and, at the same time, ensures that the barrier floats without revolving and becoming ineffective.

Inventor: SCHWARZE RIGOBERT DIPL ING
IPC: B21D7/024
Filed: 1993-10-21
Abstract: The tube bender (bending machine) has two bending heads (11,12) which are designed symmetrically with respect to one another and which project cantilever-fashion from a machine frame (10).

Patent DE-4420283-A1 (DE)
Inventor: HAGMANNS FRANZ JOSEF DIPL ING
IPC: H04B7/26
Filed: 1994-06-10
Abstract: Described is a method of synchronizing carrier frequencies in a mobile-radio network with base and mobile stations, the base stations broadcasting a synchronization signal which is received by the mobile stations and used to derive their transmission frequency. The base stations emit as the synchronization signal a family of sine waves of different frequencies. Each of the mobile stations has a selection filter by means of which at least one of the emitted sine waves can be detected. The method is insensitive to fading and permits extensive standardization of the circuits in the base stations and in particular standard processing facilities in the mobile stations.
