IPC: H01L21/60
Filed: 1971-08-04
Abstract: 1340538 Welding by pressure FERRANTI Ltd 3 Aug 1972 [4 Aug 1971] 36722/71 Addition to 1255832 Heading B3R A method of manufacturing an electrical switch contact member comprises providing a supply of spherical particles 10 of a highly conductive metal, selecting and transporting one of said particles to a selected part of a conductive support member 13 and bonding the particle to the support member by impacting it into the surface of the support member by means of an impacting tool 20. The spherical particle 10 may be of silver and the support member 18 a resilient steel strip having a thin silver coating which may itself be protected by a thin flash of gold; bonding may then be performed in a non-oxidizing atmosphere, e.g. of nitrogen. Alternatively bonds may be made between particles of gold, aluminium and copper and a surface of any one of these metals or of silver. The selection and transport of the spherical particle is preferably effected by means of a suction nozzle 12 adapted to enter a receptacle 11 in which the supply of particles is held. The tip 17 of the nozzle may be heated to 200-300‹ C. and impacting of the particle on to the support is effected initially by the nozzle and subsequently by a tungsten carbide impacting tool 20. Apparatus, Fig. 1, for simultaneously bonding silver particles to a batch of sixteen conductive supports in the form of a preformed strip 23 comprises a carrier 27 reciprocable laterally by cylinder and piston means 28 beneath a vertically reciprocable head 31 which supports a series of impacting tools 20 and suction nozzles 12. The carrier has an undercut channel 26 in which the strip 23 is mounted and along which it may be indexed, and a series of supply bins 11 for the silver particles. A supply of nitrogen to the bins agitates the particles to prevent their becoming jammed. Subsequent stamping operations sever the individual contact member from the strip 23 (Fig. 3, not shown). More than one particle may be bonded simultaneously to a given part of the support member to form a single contact area of larger size (Figs. 5, 6, not shown).

Filed: 1928-12-14
Abstract: 302,319. British Thomson-Houston Co., Ltd., (Assignees of Newkirk, B. L.). Dec. 14, 1927, [Convention date]. Purifying liquids.-In order to separate minute particles from mercury, the mercury is given a large surface which is brought into contact with the surface of a material not wet by mercury. This may be done by passing the mercury through one or more compartments filled with steel balls, pebbles, vertically arranged wire screens or similar bodies. The process is especially applicable for the separation of minute particles of steel or iron oxide from mercury used in a mercury-vapour power system. A casing 3 is divided into compartments by walls 8, 9, 10 with apertures 11, 12 so that mercury passing from the inlet 13 to the outlet 14 takes the course indicated by the arrows through beds 15 formed of steel balls or gravel, held down by wire screens 16. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the separation of minute particles from other liquids than mercury in the manner described. This subject-matter does not appear in the Specification as accepted.

Filed: 1962-10-01
Abstract: 962,305. Boning fowls. D. CUTRERA. Oct. 1, 1962, No. 37058/62. Heading A2U. The skeleton and bones of a picked, eviscerated fowl 10 are withdrawn through the single longitudinal slit 18 made in the skin between the rearward end of the breast bone 24 and the tail for eviscerating purposes, and the skin and meat remain as an integral whole which is folded and tied. The head and neck, legs and feet, wings, and tail are first chopped off and circular cuts 20, 23 then made around the leg and wing bones to facilitate the removal of tendons and ligaments. A tool 19 such as the one described in Specification 681,080, or an ordinary boning knife, is then used to remove the meat from the back frame bones, breast bone 24, rib-casing, in that order, rolling back the meat as the work proceeds so as to expose first the hip joints 25, which is severed to disconnect the thigh or upper leg bones 26, and then the wing shoulder socket joints 29 which are also severed. The skeleton is then completely freed and discarded. The legs and wings are then gradually turned inside out whilst freeing the meat from the bones as before. The carcase, which is then completly inside out, Fig. 6, is turned or rolled back, wings first, then legs, then body, so that the skin is once more to the outside. The wings are then folded back under the main body portion and the neck portion brought back to overlie them and tied with a cord encircling the body. Other cords are tied around the body and the ends of the legs are tied together. The fowl may be enclosed in a transparent plastic sheet or bag.

Title: Liquid-cooled disc brakes
IPC: B60T1/06
Filed: 1972-08-10
Abstract: 1335330 Liquid cooling of full-face disc brakes GENERAL MOTORS CORP 10 Aug 1972 [15 Sept 1971] 37297/72 Addition to 1253329 Heading F2E The liquid-cooled multi-disc disc brake of the main Specification is modified by providing temperature-responsive means adapted to compress at least a portion of the disc pack and thereby cause the pump drive disc to be clutched in driving relation when the temperature is above a predetermined minimum. As shown, at least one temperature-responsive U-shaped bimetallic clip 52 is mounted, e.g. on a housing bolt 38 and has two legs 55, 56, each of which can contact one face of a stationary disc 34: each such stationary disc is adjacent to one of the two rotatable discs 36 between which the pump drive disc 42 is located, and it is the faces of the discs 34 which are remote from the two discs 36 which are adjacent the bi-metallic clip. Thus, in operation, when the temperature of the bi-metallic clip is above a predetermined level, the shape it then adopts forces the stationary discs 34 into close contact with the rotatable discs between them, and these in turn engage the pump drive disc 42 positively, which drives the coolant-circulating pump assembly 30. Preferably several such clips are spaced circumferentially. The force with which the legs 55 and 56 engage the discs, (and thus the speed of the pump), is proportional to the temperature. When the temperature falls below the predetermined level, a clearance is established between the legs of the clip and the adjacent stationary discs 34, so pump-driving by this method ceases. Normally the above-described procedure occurs after the brake has been released but, because of the high coolant temperature, still requires pump operation for coolant circulation. Thereafter, the pump is driven at a much lower speed by viscous shear action, as described in the main Specification.

Title: Improvements in or relating to the manufacture of fluorine by the electrolysis of fused salts
Inventor: HILL HAROLD
IPC: C01B7/20
Filed: 1954-12-24
Abstract: Hydrogen fluoride present as an impurity in fluorine produced by electrolysis of a molten mixture of potassium fluoride and hydrogen fluoride is removed by scrubbing the contaminated fluorine with a molten mixture of potassium and hydrogen fluorides which is of such a hydrogen fluoride content and at such a temperature that the partial pressure of hydrogen fluoride over the scrubbing mixture is less than in the contaminated fluorine. The scrubbing mixture is then either used directly to return hydrogen fluoride to the cell or it is heated to boil off the absorbed hydrogen fluoride which is returned to the cell.

Title: Improvements in or relating to controlled-velocity drives
IPC: H02P29/00
Filed: 1964-09-15
Abstract: 1,062,825. Automatic speed controls. HEENAN & FROUDE Ltd. Sept. 15, 1964 [Sept. 19, 1963], No. 37667/64. Heading G3R. A controlled velocity drive comprises clutch coil CL1 which is energized through silicon controlled rectifier SCR1 regulated in accordance with a reference voltage and feedback signals representing the speed of a driven member and the current through the clutch coil. Rheostat R4 is initially adjusted to establish a minimum current level for the clutch coil when reference potentiometer R5 is set at zero. Further adjustment of potentiometer R5 applies a positive potential to the base of transistor TR1 for charging capacitor C5 whereby transistor TR3 is triggered into conduction and transistor TR4 is cut off. As the capacitor C5 becomes charged, transistor TR3 is cut off to cause conduction of transistor TR4 whereby a positive pulse is coupled to the gate of rectifier SCR1 for energizing the clutch coil. The resulting increase of speed of the output member is sensed by generator G which provides an increasingly negative voltage at point 17, so reducing the charging rate of capacitor C5. This reduces the conductive periods of the rectifier SCR1 and the energization of the clutch coil until the speed of the driven member is stabilized. The response time of the system is reduced by a negative feedback loop comprising resistor R26 for sensing the current through coil CL1. Incipient current-variations are reflected back to the junction 17. Transistor TR2 operates to maintain the conductivity of transistor TR1 substantially independent of temperature changes.

Title: Improvements in the manufacture of carbon monoxide-containing gases
IPC: C10J3/46
Filed: 1938-12-29
Abstract: 523,221. Gas generator plant and processes; carbon dioxide. POWER-GAS CORPORATION, Ltd., and RIXON, F. F. Dec. 29, 1938, No. 37693. [Class 55 (i)] [Also in Group III] Gases rich in carbon monoxide are made by passing carbon dioxide through a heated fuel bed during the run, the carbon dioxide for use in the process being obtained partly by recovery from the run gases, and partly from the blow gases. During the blow period, air from a blower 5 passes through the fuel bed of a gas generator 1, and the blow gases are burned with air in a combustion chamber 13 from which the hot gases pass to a waste heat boiler 14 and scrubber 17 where they are cooled and cleaned by water, any sulphur dioxide being removed. A booster 23 delivers the gases to a CO 2  absorber 24 through which circulates a solution of either alkali carbonate, or organic amines such as ethanolamine, or alkali salts of amino-propionic acid. Waste gas passes to an.outlet.25 and the used absorbent is forced by a pump 26 through a heat exchanger 29 to the top of a regenerator 32, the bottom portion of which is heated by steam pipes 33. The hot regenerated absorbent passes back through the heat exchanger 29 and cooler 30 to the top of the CO 2  absorber 24. The CO 2  passes through a cooler 36 to a gas holder 41, the condensate from the cooler flowing to a tank 39, and to the suction side of the pump 26. During the run, CO, from the gas holder 41 passes through a dryer 45 in an up or down run through the generator, and the resultant carbon monoxide passes to a scrubber 20 where it is washed and cooled with water, the gas passing to a CO 2  absorber 47 from which pure CO is led off through an outlet 48. The spent absorbent is delivered by pump 26 into the recovery circuit above described from which the regenerated absorbent passes by a valve 64 to the absorber 48. Steam may be admitted to the fuel bed through pipes by-passing the dryer 45.
