Patent GB-2045482-A (GB)
Title: Checking program stores in programmed machine tool control system
IPC: G05B19/406
Filed: 1980-03-13
Abstract: In numerical controls of machine tools, the downwards (lengthwise) sum of the programmed information of each system program memory (SP1) is stored in an additional memory. For later checking of the memory contents, the downwards sums of the respective memories on the control side are formed and are compared with the stored information. If a sum deviates, a trouble signal is given out as an indication of the defective memory.

Patent GB-2113590-A (GB)
Title: A method of bonding a semiconductor to a mounting member
Inventor: MACDONALD BRIAN MICHAEL
IPC: H01L21/603
Filed: 1981-12-01
Abstract: The method finds application in the bonding of a transistor to its mount or, as particularly described a semiconductor laser die to its heat sink. Known bonding techniques employ indium or gold alloy solders and suffer, inter alia, from problems of low thermal conductivity or low ductility (which causes stress induced defects in the laser die). The method described uses a pure gold preform (4) which is annealed and then located between gold plated bonding surfaces (6, 5) of the laser die (1) and the heat sink (2) for forming thermocompression bonds therewith. The resulting monometallic bond possesses good thermal conductivity and has a ductility which causes fewer stress induced defects. <IMAGE>

Title: Flue gas desulphurisation
Inventor: STEWART ROBERT D
IPC: B01D53/81
Filed: 1982-09-22
Abstract: A process is disclosed for obtaining additional flue gas desulfurization using waste solids from a fluidized bed combustion system in which sulfurous fuels are burned in a bed of acceptor particles. The process comprises the steps of: withdrawing coarse waste particles from the fluidized bed combustion system (10); subjecting coarse waste particles to mechanical grinding means (30) for attrition and disintegration whereby the waste particles are reduced to a finely divided chemically reactive state (33); and, injecting the finely divided waste particles into the fluidized bed combustion system (10) whereby additional flue gas desulfurization is achieved. In an alternative, the finely divided particles may be used in gas scrubbing (42, 46), in dry form or in the form of a solution or suspension (slurry). <IMAGE>

Patent GB-2117432-A (GB)
Title: Piles
Inventor: FLEMING WILFRED GEORGE KENNETH
IPC: E02D5/38
Filed: 1983-01-04
Abstract: The method involves driving into the ground a mandrel (1) carrying a pile shoe (2) and pumping a cementitious mixture (4) into the hole through the interior of the mandrel (1) as it is being driven into the ground. The cementitious mixture (4) leaves the interior of the mandrel (1) and enters the annular gap between the mandrel (1) and the earth surface via one or more holes (34) located at or close to its lower end and generally just above the pile shoe (2). The mixture (4) is maintained at a positive pressure relative to its surroundings, and is allowed to set after the mandrel (1) has reached the desired depth and has been withdrawn leaving the shoe (2) behind. The driving rig need not have the bulk required to exert the massive pulling forces required in conventional piling systems where a temporary casing which has been driven tightly into the soil is withdrawn prior to completion of the pile.
Patent GB-2117099-A (GB)
Title: Refrigerated display case
Inventor: IBRAHIM FAYEZ F
IPC: F25D21/06
Filed: 1983-02-08
Abstract: A refrigerated display case has an access opening (6) in the front wall (4) and an air conduit (16) extends in an approximately C-shaped formation around the display case. The air conduit (16) has openings (20, 22) at both end, located on opposite sides of the access opening (6). Arranged within the air conduit (16) is at least one reversible fan (18) and a set of refrigeration coils (26). During a refrigeration cycle the fan (18) circulates air through the air conduit in a first direction past the refrigeration coils (26) and across the access opening (6). When frost buildup within the display case has reached a certain level, the system is switched to a defrost cycle. During the defrost cycle, the fan (18) circulates in the opposite direction (as shown) through the air conduit (16) and draws in ambient air, from outside of the display case, which serves to defrost the system. The ambient air, after passing over the evaporator coils and through the air conduit (16), is expelled from the air conduit in a direction towards the outer side of the refrigerated case so as to move away from the interior of the case. <IMAGE>

Abstract: Inert gas is supplied to a closed reagent reservoir 16 to force reagent along a conduit 22 into a vessel 10 containing a liquid sample so as to produce gaseous measuring samples according to the "hydride method", which gaseous samples are passed to a cuvette 42. A manometric switch 24 closes a valve 20 located in the connecting conduit 18 when a pre-set pressure is reached in reagent reservoir 16. After passage of the gaseous samples valve 38 is closed and inert gas pressure in sample vessel 10 forces residual liquid through valve 44 to waste. <IMAGE>
