Patent GB-989374-A (GB)
Title: Improvements in or relating to the treatment of the waste gases from the electrolytic production of aluminium
IPC: C01F7/54
Filed: 1961-07-03
Abstract: Fluorine and/or aluminium values in the form of sodium and/or aluminium fluorides are recovered from the soot contained in the waste gases produced in the electrolytic production of aluminium, by calcining an intimate mixture of the soot and sodium carbonate at 750 to 1100 DEG  C. until no free or combined carbon remains, and leaching the resulting ash with water to obtain a solution containing sodium and/or aluminium fluorides.  The soot may be eliminated from the waste gases by physical processes which may be dry (e.g. use of electrostatic filters or cyclones), or wet (washing the gases with an acidic or basic solution).  The combustion of the carbon and tar contained in the soot initiated by an auxiliary heating is sufficient to maintain the calcination temperature. The liquor resulting from the leaching may be separated from the residue, consisting mainly of insoluble oxides, by filtration and treated with fluorine and/or aluminium compounds to precipitate cryolite.  Specification 989,373 is referred to.

Patent GB-443156-A (GB)
Title: Improvements in or relating to transmission belts
IPC: F16G1/04
Filed: 1934-08-21
Abstract: Endless belts impervious to liquids and gases are made from a tubular loose-mesh fabric, woven from the textile elements described in Specification 422,960, which is treated without tension by an agent, e.g. an acid or alkali, such as caustic soda, which produces a contraction in length and swelling of the fibres, and is then impregnated with rubber or rubber-like material which is vulcanized. The tubular fabric is cut into rings of width corresponding to that of the belts desired.  The cuts may be made perpendicularly to obtain a rectangular section or obliquely to obtain a trapezoidal or triangular section.  Impregnation is effected, after washing, by rubber solutions or dispersions of natural, artificial or regenerated rubber.  Vulcanized latex may be used.  Vulcanization, or coagulation, where a vulcanized latex is used, may be done with or without tension, or without tension but whilst still under the effect of tension previously applied. Belts may be made of such length as to connect pulleys with a definite fitting tension without elongation. In a modification the tubular fabric is made of such a length that a belt of the desired width is obtained without cutting.

Title: Matrix selection circuit
IPC: H03K17/66
Filed: 1965-06-08
Abstract: 1,079,877. Pulse storage matrices; transistor gating circuits. SPERRY RAND CORPORATION. June 8, 1965 [June 16, 1964], No. 24206/65. Headings H3B and H3T. In order to reduce the number of components in a large magnetic memory matrix, each bit-driver, e.g. 15, and sense amplifier, e.g. 12, are connected via bi-directional switches, e.g. B(1,n), to several (as shown, three) bitdrive lines 28. Each bit-drive line comprises a conductor coated with an anisotropic thin magnetic film and having a bit storage location, e.g. 30, at each intersection of the bit-drive line with a word-drive line, e.g. DR1. The corresponding bit storage locations, e.g. 30, 30<SP>1</SP>, 30<SP>11</SP>, of the different groups 7, 8, 9 together form a word so that several words (as shown, three) may be served by each word-drive line. To read out the word 30, 30<SP>1</SP>, 30<SP>11</SP>, select-drive line 37 is energized to close switches B(1,n), B(2,n) and B(m,n) and word-drive line DR1 is energized to induce a pulse of informationdependent polarity in each bit-drive line, which pulses pass through the respective switches to the respective sense amplifiers. To write in information into location 30, select-drive line 37 and word-drive line DR1 are energized and bit driver 15 is energized to drive a pulse of information-dependent polarity, via switch B(1,n), through the related bit-drive line 28. Three suitable bi-directional switches are described. In Fig. 2 (not shown), a switch (e.g. B(1,n)) comprises a PNP transistor and an NPN transistor, the sense amplifier and bit driver being each connected to the emitters of both transistors and the bit-drive line being connected to the collectors of both transistors. Select-drive line pulses are applied directly to the base of the NPN transistor and via an inverting transformer to the base of the PNP transistor. In Fig. 4, the select-drive line pulses are applied to the bases of bilateral transistors Q3, Q4. Transistor Q5 is connected to a second bit-drive line 50. In Fig. 5 (not shown), there is only one bilateral transistor (Q3 or Q5) for each bit-drive line and a PNP transistor (Q6) or diode is used to conduct the select-drive pulses away from the sense amplifier.

Patent GB-914977-A (GB)
Title: Improvements in and relating to thermally actuated valves
Inventor: BARNES HUGH VERNON
IPC: G05D23/02
Filed: 1961-07-05
Abstract: 914,977. Valves. RADIATION Ltd. July 5, 1961, No. 24239/61. Class 135. A thermally-actuated valve comprises a housing 1, a ball-valve 20 spring-pressed towards a seating 2, a plunger 19 adapted to displace the ball away from the seating by moving it laterally in relation to said seating, and a thermo-sensitive element operably associated with the plunger adapted to enable the plunger to be displaced so as to permit the ball to approach the seating to close the valve or to urge the ball away from the valve seating so as to open the valve, upon a particular change of temperature. As shown in Fig. 1, the plunger 19 is acted upon by a stainless steel strip, which constitutes the thermo-sensitive element 13, the latter being bowed so as to normally hold the ball off its seating. When a gas pilot light 16 is lit, the strip bows still further so as to permit the ball to seat and close a port leading to atmosphere. An alternative arrangement, the strip 13 may be bowed in the opposite direction, so that when the pilot light is alight, the ball if off its seat and permits the flow of gas to a burner; when the pilot light is extinguished, the ball recedes and the gas flow stops. Specifications 897,134 and 914,978 are referred to.
Patent GB-506129-A (GB)
Title: Improvements in or relating to methods of fabricating detachable drill bits
IPC: B21K5/06
Filed: 1938-08-18
Abstract: 506,129. Making detachable drill bits. COOK, C. E. Aug. 18, 1938, No. 24308. Convention date, Sept. 3, 1937. [Class 83 (iv)] In making detachable drill bits, particularly rock drill bits with a dovetail tang part, the stock A, previously formed at one end with partly formed cutting edges as shown in Fig. 1, is placed between dies 1, 2, Fig. 3, mounted respectively in the reciprocable ram 3 and the lower die block 4 of a conventional drill sharpener. When the ram is brought down, the body part B and dovetail tang C are formed without completely severing the bit. Thereupon a dolly 15 operates to sharpen the cutters and gauge the bit, after which the bit is severed by striking with a hammer. Plates 19, 20 on the dies serve for aligning the work therein. To pierce the formed bit, it is reheated and a punch element 31, Fig. 8, is mounted on the ram 3, and vice jaws 24, 25, one of which is movable clamps the bit. After the punch forms the hole in the bit the latter is removed and hardened for use. Specification 506,130 is referred to.

Title: Method of making plane junctions on a semiconductor monocrystal and semiconductor devices manufactured according to this method
IPC: C30B19/02
Filed: 1961-07-06
Abstract: 963,275. Semi-conductor devices. COMPAGNIE FRANCAISE THOMSON-HOUSTON. July 6, 1961 [July 6, 1960], No. 24502/61. Heading H1K. Two closely spaced junctions are formed in a semi-conductor body by placing a pellet of semi-conductor material containing both donor and acceptor impurities upon a block of monocrystalline material having the same conductivity type as that of the predominant impurity in the pellet, this impurity having the smaller diffusion coefficient of the two, melting the pellet and consequently the adjacent surface of the block, recrystallizing the melted portion, and then maintaining the temperature at such a level that the impurities in the recrystallized zone partly diffuse into the unmelted region in a zone of which the conductivity type is reversed by the faster diffusing impurity. The unheated surface of the monocrystalline semi-conductor block rests on a supporting device which is designed to cool the block during the process in such a way that the iso-thermal surfaces are approximately plane near the border between the recrystallized zone and the unmelted part of the block. A slab containing two parallel junctions may be dried to provide several H.F. transistors, and in one embodiment, Figs. 1 and 3, a block 1 of N-type Si, resting on a hollow cylinder 5 of quartz or molybdenum which is cooled by coil 6, has a resistivity suitable for the collector zones of such transistors, e.g. 3 ohm. cms. The N-type Si pellet 3, containing A1 and As as impurities, is heated by an induction coil 4 made convex towards the pellet to avoid overheating of the circumferential regions of the melted zone. The process is carried out either in an evacuated enclosure or in an atmosphere of an inert gas such as argon. A trial and error method is used to initially determine the dimensions, positioning, and rate of cooling of the hollow cylinder 5, cross-sections of the various slabs being examined after each test. In Fig. 5 (not shown), the semi-conductor block again stands on a hollow cylinder but cooling is carried out by directing a stream of inert gas on to the underside of the block. To obtain a flat slab, Fig. 6, more suitable for dicing, a thin foil 17 of inert refractory material may be placed on top of the pellet during the heating process and removed when the device has been formed. Suitable foil materials are quartz and, except in the case of Si semiconductors, graphite.

Title: Images in or on photosensitive or luminescent materials
IPC: G03C5/26
Filed: 1970-05-20
Abstract: 1318371 Reducing grainy appearance FUJI SHASHIN FILM KK 20 May 1970 [ 21 May 1969] 24512/70 Heading G2C [ Also in Divisions C4 and H1] The apparent graininess of a photographic or phosphor screen image is reduced by dividing the image into a plurality of sections in the form of a grid pattern, the spacing between the centres of the grid elements being smaller than the spacing between the clumps of particles forming the image. The grid pattern can be black or white. Fig. 4A shows part of a photographic image in which the silver particles are clumped together into a number of separate areas 7, producing a grainy effect. Fig. 5A shows the same image with the areas divided into a grid pattern according to the invention, the effect being to reduce the grainy appearance. The grid pattern may be imposed in various ways. It may be printed or laminated on the protecting layer of the photosensitive sheet, or formed as a latent image on the sheet, or optically projected thereon. The grid may be a line grid, as in Fig. 5A, or composed of contiguous circular elements, as in Fig. 12A, in which case the grid spacing is the distance between adjacent centres. As applied to the phosphor screen of a cathode ray tube, the grid structure may be applied in front of or behind the screen.
