Title: Separation of gas mixtures by pressure swing adsorption
Inventor: GARRETT MICHAEL ERNEST
IPC: C01B13/02
Filed: 1987-09-03
Abstract: A gas mixture, typically air, is separated by pressure swing adsorption. Compressed air is passed into a bed 12 of carbon molecular sieve. Nitrogen is the least readily adsorbed component of the mixture and a gas mixture enriched in nitrogen flows out of the bed 12 into a reservoir 28. At the end of the adsorption step communication between the bed 12 and air compressor 4 is ended and the bed 12 is placed in communication with bed 14 (at atmospheric pressure) to equalise the pressure therebetween. The bed 12 is then regenerated by placing it in communication with the atmosphere via conduit 34 while the bed 14 is placed in communication with the compressor 4 and nitrogen-enriched gas mixture continues to be produced. The pressure between the beds 12 and 14 is then equalised. During this cycle according to the invention there is a bleed of nitrogen-enriched gas mixture back into the beds 12 and 14 from reservoir 28 via conduit 42 and pipe 44 whenever the pressure in at least one of the beds 12 and 14 is less than the pressure in the reservoir 28. <IMAGE>

Title: Fine machining rotationally symmetric outer surfaces on work pieces
Inventor: HAHN ROLF-DIETER
IPC: B23D77/02
Filed: 1987-12-15
Abstract: Fine turning of rotationally symmetric outer surfaces on work pieces is carried out by a geometrically defined cutting edge (42, 44) which is guided on the outer surface by additional means, such as guide strips (50), which are supported on the work piece and are arranged together with the cutting edge (42, 44) in a cutting head (34), a flexible tool carrier (20) enabling the cutting head (34) to line up in parallel or coaxially with the work piece. Centring errors of the cutting edge (42,44) of the tool, in particular of an interchangeable tool supplied manually or automatically, are thereby automatically compensated to the extent that a predetermined fine-machining tolerance for a shaft is not exceeded. <IMAGE>

Title: Excimer laser trimming of resistor
Inventor: KIRBY PETER LINLEY
IPC: H01C17/242
Filed: 1988-08-06
Abstract: The electrical resistance value of a polymer thick film resistance element on an electrically insulating substrate is adjusted to a desired value, measured between conductive terminations, by removing polymer thick material of the resistance element using an excimer laser. Alternatively, one or more polymer thick film electrical conductors is or are provided on the substrate and arranged to shunt portions of the resistance element. The excimer laser is then used to selectively cut through the one or more polymer thick film conductors to provide step-wise adjustment of the resistance value, measured between the terminations. The process is advantageous in that, unlike other lasers, the excimer laser does not cause charring of the organic polymer material.
