Title: Gas treatment method and apparatus
Inventor: ATKINSON TIMOTHY DAVID
IPC: F25J3/02
Filed: 1986-07-17
Abstract: A method of forming gas mixture of hydrogen and nitrogen typically suitable for use as an ammonia synthesis gas includes passing crude hydrogen through an array 2 of heat exchangers 4, 6 and 8 to refrigerate the hydrogen. The crude hydrogen is then introduced into a nitrogen wash column 20 in which it is washed with a nitrogen stream liquefied by passage through the heat exchanger 4, 6 and 8. Carbon monoxide, methane and other such impurities are thereby removed from the hydrogen and a gas mixture of nitrogen and hydrogen is returned from the top of the column 28 through the heat exchargers 8, 6 and 4. To provide refrigeration for the process, a stream of nitrogen is compressed in compressor 40, expanded in expansion turbine 44, liquefied by passage through heat exchanger 8 and then pumped by pump 48 into a mixer 31 in which it is mixed with the mixture of nitrogen and hydrogen. Evaporation of the liquid nitrogen component of the mixture helps to provide additional refrigeration for the process. <IMAGE>

Title: Cutting blades with teeth, in particular hedge clipper knives, and a method of manufacturing them
Inventor: CHANTON MARZELL
IPC: B23K26/38
Filed: 1987-03-18
Abstract: It is proposed that cutting blades (1,2), in particular of hedge clipper knives, be provided with teeth (3) and tooth gaps (4) which fit into each other in their shape and are different in their size merely by the resulting width of a parting cut placed between them. Thus a tooth row (3) of a hedge clipper knife (1) and a tooth row (3) of an adjacent, second hedge clipper knife (2) can be cut out at the same time with one cut. It is further proposed to execute these parting cuts by means of a laser beam. Thus several hedge clipper knives can be cut out of a large, hardened steel plate without a large loss of material. As a result of the parting-cut method selected, these knives have cutting edges of greater hardness and therefore longer life. <IMAGE>

Filed: 1988-03-18
Abstract: A glazing support 14 is anchored to a window rebate 12, 13 and comprises a base 23 supported at the rear by an elongate leg 21a. A pane of glass is received in a channel support 16 and a gutter 20 is provided adjacent the base of the glass 15 for receiving condensation therefrom. The base is covered. As the glazing support 14 is hollow the condensation is drained away along the base 23 via a first and second plurality of weep holes 22 and 29 in the gutter 20 at the front of the base 23 respectively. The gutter 20 is concave for easy finger wipe. Futhermore the glazing support 14 can accommodate a higher by trimming the bottom edge of the elongate leg 21a. In a second aspect of the invention the base 23 is anchored to the window rebate 12,13 by a ridged rib 33. The ridges provide better grip on putty, but preferably a resilient socket fixed to the window rebate releasably mates with the ridged rib 33. <IMAGE>

Patent GB-2239244-A (GB)
Title: Moisture-resistant electrically conductive cements
Inventor: DURAND DAVID
IPC: H01R4/04
Filed: 1990-11-13
Abstract: An electrically conductive cement which when used to bond electrically conductive mating surfaces provides substantially stable conductivity characteristics under high humidity conditions; comprised of a carrier that provides a volumetric shrinkage of more than about 6.8% (vol.) and a conductive filler including agglomerates, particles, powders, flakes, coated nickel particles, and coated glass spheres, having size and surface characteristics that maintain stable electrical contact by forming a moisture resistant contact with an electrical component lead. The carrier having a volumetric shrinkage between the uncured and cured states of greater than about 6.8% (vol) appears to effect a compaction of the filler particles causing the particles to be forced into enhanced electrical contact with the surfaces to be connected and to provide a measure of compaction between the particles themselves to enhance particle-to-particle conduction. The shrinkage of the polymeric carrier during curing places the interior particles under compression with sufficient force to urge the particles into engagement with one another as well as to cause the particles to penetrate non-conductive oxides that may be present on a component lead. <IMAGE>

Title: Addressing of chained circuit modules
Inventor: WARREN KENNETH DAVID
IPC: G11C7/22
Filed: 1990-11-19
Abstract: An addressing system for circuit modules has the modules connected in a chain by forward and return data paths. Each module includes an address decoder 74 which is responsive to a received address to place the module in an addressed state. A command decoder 54 is responsive to commands received whilst the module is in the addressed state to cause it to execute one of a plurality of commands. The address and command are received asynchronously by all modules in the chain and data generated by a module in response to the address and command is passed to an adjacent module via the return data path in synchronism with a clock signal. Each module may contain a delay means 50 between its memory and/or processing circuitry 40 and the return data path, which provides a delay such that the time between a controller sending out a command to a module and receiving data generated in response thereto is substantially the same for each module in the chain. <IMAGE>
