Abstract: 895,139. Forming fibre webs. CALLAGHAN & SON Ltd., A.E. April 30, 1959 [Jan. 30, 1958], No. 3200/58. Class 120(1) Apparatus for forming pads or padding from fibres includes a fibre opener feeding the fibres into a duct through which an air-stream is impelled, the duct being constructed to give rise to a rapid acceleration and then a rapid decelleration of the air-stream so that the fibres are deposited as a loose shower upon foraminous condensing means. Fibres are fed to an opener drum 10 from a hopper (not shown) that supplies fibres to a belt 12 and rollers 14, 15. Slats may be fitted between the spikes of the drum 10 to reduce their effective length. From the drum 10 the fibres enter the duct 8 in which a Venturi effect is set up by airflow over the hump 17. Beyond the hump 17, the velocity of the air flow decreases and the fibres are showered on to foraminous condensing drums 5, 6, the relative positioning of which is adjustable. A modified form of the apparatus has a duct of rectangular cross-section of constant height but provided with a tube extending across the duct and adjustable in height or longitudinal position and which may be skewed to constrict the duct. According to the Provisional Specification materials treated may be fibre glass, asbestos, jute, coir, horsehair, hog's hair, flax, wool, cotton, linseed, sisal, string, rope, leather, paper, and plastics (e.g. acetate or viscose).

Abstract: 1,018,724. Photo-electric devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 25, 1963 [Jan. 29, 1962], No. 3234/63. Heading H1K. In a photo - electric cell in which a plate - shaped photo - sensitive body having an electrode system on one side thereof is contained in an elongated tubular envelope, with the electrode supply leads taken through a sealed aperture in the envelope, a metal cooling plate is provided which has one part within the envelope in thermal contact with the plate-shaped body on the side remote from that carrying the electrode system and a further part insulated from the supply leads and passing through the envelope seal to the outer atmosphere. In one embodiment (Fig. 1a) a sintered cadmium sulphide plate 2 housed in a tubular glass envelope 1 has a comblike electrode structure 4 and 5 formed by vapour deposition on one face thereof and is adhesively secured on its back-face by an epoxy resin layer to a copper cooling plate 8 (Fig. 1c). Two U-shaped clamping members 13 and 14 of copper and nickel are provided to embrace the edges of the body and the cooling plate insulated from the latter by a film of epoxy resin but in electrical contact with the electrode system on the body. An extension 9 of the cooling plate 8 projects beyond a sealed aperture in the envelope and may be finned to improve thermal contact with the ambient atmosphere. Sealing of the envelope is effected by means of a quartz plug 12 and resin filler 11, the packing material 18 being a silico-organic grease. In a further embodiment, Fig. 2 (not shown), a more symmetrical seal structure is provided, with the supply leads led out each on one side of a centrally disposed cooling plate. A further embodiment, Fig. 3 (not shown) is distinguished by the provision of a film layer of silicone-base lacquer on the electrode side of the body on which are arranged two pieces of copper gauge separated by a gap and in thermal contact with the cooling plate through the clamping members. The envelope may be of a synthetic material instead of glass and the filling members, to be incorporated in the seal, to be of nickel and iron alloys to compensate for expansion differences. Cadmium selenide photo-sensitive bodies are also envisaged in this construction which lends itself to mass production processes. The cooling plate may be of anodized aluminium and a low temperature metal to glass sealing operation is described in which the glass wall is coated with gold or silver and the cooling plate soldered thereto using a tin-indium solder.

Title: Improvements in or relating to semi-permanent memory devices
IPC: G11C17/02
Filed: 1965-01-26
Abstract: 1,062,953. Semi-permanent memories. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. Jan. 26, 1965 [Jan. 27, 1964; Aug. 7, 1964], No. 3341/65. Heading G4A. A semi-permanent memory of the type in which a selectively punched conductive card is placed between driving and sensing wires is characterized in that the driving and return wires are electrically balanced and are formed as printed wires in the shape of a square-toothed wave. This arrangement has advantage that since the capacitance between the wires and the card is the same, the voltage of the card is always zero and hence sensing noise is reduced, and the further advantage that an electrostatic coupling between the wires assists to increase the output signal. Reference is made to the memory disclosed in Specification 954,299, and the disadvantages thereof. The memory depicted in Figs. 6a-6e (not shown) comprises a qxp array of modules, each module containing mn-bit words, the square-toothed-wave shaped driving and return wires (Fig. 6a) being connected by surge impedances (609). The sensing lines (Fig. 6b) are straight, the output terminals being arranged alternately at opposite ends of the lines. The sensing lines may be arranged as printed conductive lines on a flexible insulated backing ribbon, the ribbon being wound in an interleaved manner (as in Fig. 6d). The data cards may be formed as a conductive metal foil coated on both sides with an insulating coating, a " 1 " being represented by a rectangular hole and a " 0 " by no hole, a string of " 1's " being represented by a single rectangular hole of greater width.

Title: Improvements in and relating to coating compositions
IPC: H01B3/30
Filed: 1961-01-30
Abstract: A coating composition, curable by heat, comprises 100 parts by weight of a polyvinyl acetal, containing 1-35% by wt. of ester groups and 3-15% by weight of hydroxyl groups; 20-200 parts by weight of a polyurethane of formula <FORM:0975455/C3/1> in which R is aliphatic with up to 8 carbon atoms, aromatic with up to 13 carbon atoms or alicyclic with up to 6 carbon atoms, or is an integer from 2-10, and R1 is the residue of a polyhydric alcohol; 0.5-20 parts by weight of either a condensate of melamine with an aldehyde and an alcohol, or a condensate of melamine with an aldehyde, an alcohol and an aryl sulphonamide; and 30-150 parts by weight of a soluble, heatcurable phenol-aldehyde resin.  Lists of starting materials for forming the various ingredients of the compositions are given in the Specification. The ingredients are preferably dissolved in an anhydrous organic medium e.g. ethylene dichloride, trichlorethylene, or mixtures of alcohols, phenols, esters and hydrocarbons. The compositions form insulating coatings on wires.  In examples compositions are used which contain, 1 to 5 polyvinyl formal (10 1/2 % acetate groups, 6% OH groups and 83.5% formal groups), a polyurethane of formula <FORM:0975455/C3/2> in which Y is phenyl; a 50% solution in cresylic acid of a phenol-aldehyde resin-"Resinol 445B" (Registered Trade Mark); and a 67% solution in xylene of a butylated melamine-formaldehyde-p-toluene sulphonamide condensate. A solvent mixture of naphtha and cresylic acid was used, and six coats of the composition were applied to magnet wire, each coat being backed before application of the next. Examples 2 to 5, 6, 7 and 11 are broadly similar to Example 1 with some variations in the proportions of the ingredients. Other examples employ a polyvinyl formal stabilized with an alkali hydroxide in place of ammonia, or a polyvinyl butyral; a polyurethane which is the phenolic adduct of the trimer of tolylene diisocyanate; and slightly different phenol aldehyde and melamine aldehyde resins.  Specification 652,420 and U.S.A. Specification 2,307,588 are referred to.

Abstract: 527,214. Refrigerating. BLOCH, R., FORTUNE, H. J., GARRARD ENGINEERING & MANUFACTURING CO., Ltd., and BEE-GEE REFRIGERATOR, Ltd. Feb. 2, 1939, No. 3542. Drawings to Specification. [Class 29] Absorption systems.-The supply of heat to the generator-absorber of a reversing system, particularly one employing a solid absorbent, is controlled by a thermostat responsive to the temperature of the generator-absorber and by another thermostat responsive to the temperature of a heat-insulated liquid refrigerant receiver associated with the evaporator, which is immersed in a brine tank or like cold accumulator. The heat leakage from the atmosphere to the receiver at the end of the absorptionevaporation period causes the receiver to rise in temperature, and its thermostat permits the start of a heating period. When the receiver temperature is lowered, due either to the evaporation period or to low atmospheric temperature, the heat supply is interrupted. Preferably expanding bar thermostats are used, in conjunction with snap-action valves as described in Specification 481,158, [Group XXIX], controlling gas fuel supply.

Abstract: 1,014,099. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 28, 1964 [Jan. 28, 1963], No. 3613/64. Heading H4P. In a demodulator for frequency-shift binary data a flip-flop 13 pulses at each positive-going transient from limiter 12, and flip-flop 18 pulses briefly at each negative-going transient. Flipflop 13 feeds flip-flop 14 which in turn feeds AND gate 16 and, via flip-flop 15, AND gate 17. The timings of the astable periods of the flip-flops are such that the short pulses from unit 18 pass via gate 16 when the higher frequency waveform is received, and via gate 17 when the lower frequency is received. The number of pulses passed by the gates per bit will correspond to the number of cycles in each received bit. Filter 22 acts as a threshold unit so that toggle 21 pulses only after reception of a preset of pulses, so that spurious signals do not operate the toggle.

Abstract: 346,078. Filters. VERNAY, J. B., 19, Rue du Gaz, Villeurbanne, Rhone, France. Feb. 3, 1930, No. 3642. Convention date, May 18, 1929. Addition to 345,383. [Class 46.] A horizontal row of rotary filter elements as described in the parent Specification is arranged in each of two superposed vats, all the elements being rotated by means of a single chain. Figs. 3 and 4 show a modified form of filter element. The element is supported by short axles 1, 41, each associated with an end-plate 42, 44. The axle 1 is carried on an open bearing as described in the parent Specification. The plate 42 carries a closed cylindrical body 43 which leaves only a narrow annular space within the filter wall 2, so that when the solid matter has been detached from the element by air pressure, only a small quantity of air, which will not interfere with the working of the suction pump, is left within the element. The hollow axle 41 makes joint 16 with a continuation shaft 46 by which the element is rotated and through which the filtrate is discharged into a hollow body 50. The body 50 is provided with a distributer cock, the plug of which has a transverse passage 53 and two longitudinal grooves 55 by means of which the body 50 can be put into communication respectively with a filtrate suction pipe 54 and a pipe 56 leading to a reservoir of compressed air. The chain which drives the element by means of a wheel 48 on the shaft 46 carries one or more pairs of tappets 60, the members of a pair being only a short distance apart. The first member of each pair turns the plug so that air under pressure is supplied to the element and the second member moves it to a position in which filtration is resumed. Fig. 7 shows a modified arrangement of distributer valve. The outlet from the body 50, the air-pipe 56 and the filtrate outlet pipe 54 communicate with openings 83, 84, 82 respectively in a member 80, over which a valve plate 78 is rotated. This plate has a circular groove 86, Fig. 8, and a radial groove 87. It is rotated by means of a toothed wheel 88 which is engaged by a tappet 89 on a wheel 90 by which the shaft 46 is driven. For the major part of each rotation the opening 83 is in communication with the opening 82 by way of the groove 86, but for a short period this communication is broken, and the openings 83, 84 communicate by way of the groove 87. The wheels 90 of the several cells may be geared together, the drive being effected by one of them.
