Title: Removal of chloro:fluoro:carbon gas from insulation foam - a pulveriser and compressor in separate airtight chambers extract gas which is removed, collected and condensed to form pure liquid CFC
Inventor: SCHMIDT HANS-JOERG DIPL ING
IPC: B03B9/06
Filed: 1989-05-11
Abstract: A process (P) for recovery of chlorofluorocarbon gas (CFC) from plastic foam is described. Foam is delivered to a pelletizer where it is reduced to a powder. Air is excluded during the process. During pulverizing CFC gas is released from the foam pores and is extracted and combined with further CFC gas released when the powdered plastic is compressed, also in an airtight area. Gas from both areas is condensed and the fluid CFC is collected. Equipment consists of an airtight chamber with a pulverizer, an airtight valve and a gas extraction unit. A second airtight chamber connected to the first has a compression section and a gas extraction unit. A condenser is provided to convert extracted gas into fluid CFC. USE/ADVANTAGE - (P) is for removal of CFC gas from insulating foam particularly in refrigerators and freezers. (P) produces impurity free CFC fluid and is an environmentally acceptable process which is simple to perform.

Filed: 1990-02-10
Abstract: The wall component, to clad the outer wall of a building, is an outer skin section (1) secured to the carrier plate (4) by at least two layers of different inorganic adhesives, spread over the whole surface, which are heat resistant to a temp. above 1000 deg. C. The adhesives are selected so that, on heating, the diff different coefficient of expansions of the outer skin (1) and the carrier plate (4) are compensated. The adhesives are also strong enough to withstand pressure and suction forces applied by wind, and any resulting interior tensions within the cladding. The lower edge of the outer skin (1) is supported by the horizontal surface of the carrier rail (8). Pref. the carrier plate (4) is composed mostly of a fibre cement, and the outer skin (1) is of ceramic plates or plate material especially of Cu or steel plate. The surface of the outer skin (1), away from the building facade (10), is enamelled, eloxided or lacquered. The carrier rails (8) are of extruded Al profiles. A profiled bar (9) is fixed to the carrier frame (6) and/or the carrier plate (4), with a downwards surface as a set seating for the upper edge of the outer skin (1). The shapes of the profiled bar (9) and the carrier frame (8) are structured so that an optically sealed barrier is between two wall units, above each other, to prevent water penetrating from the outside, and also to give a water guide and rear ventilation to the facade. e 9 sleeved screws (5) with anchors secure the wall units to the carrier frame (6). At least two inorganic adhesives are used, between -15 to +80 deg.C without affecting their adhesion. ADVANTAGE - The system gives a wall cladding unit which is stable, and without visible anchoring to the carrier, which can be attached to the building to give a clean appearance.

Patent DE-4016309-A1 (DE)
Inventor: FEHLMANN WOLFGANG
IPC: F02M59/36
Filed: 1990-05-21
Abstract: The fuel-injection pump proposed is fitted, for the amount of fuel injected at high pressure, with a solenoid valve (34) which controls a channel (33), which acts as a fuel-pressure relief channel, leading from the pump cylinder (10) to an aspiration space (17). When the valve (34) closes, fuel can be pumped at high pressure to the injection nozzle (13). During the suction stroke of the pump, the same valve allows the pump cylinder to fill from the aspiration space (17). In order to keep the cross-sectional area of the solenoid valve small, a one-way valve (16) is fitted, in parallel with the solenoid valve, in a filling channel (15) leading from the aspiration space (17) to the pump cylinder (10).

Title: Combined magnetic video recording and playback head - has pair of pseudo gaps set as different angle to main gap to minimise noise
Inventor: HIRANO AKIYOSHI
IPC: G11B5/187
Filed: 1990-09-25
Abstract: A combined magnetic head (21) for the recording and playback of video signals has a main gap (1) and pseudo gaps (2).  The azimuth angle of the main gap relates to that of the video signal (12) and a recording azimuth (13) of a frequency modulated audio signal relates to the main gap.
