Title: Process for preparing linear copolyesters
IPC: C08G63/64
Filed: 1964-05-13
Abstract: Thermoplastic copolyesters are made by reacting (a) 100 mol per cent of bisphenol A with (b) 10-70 mol. per cent of a diaryl terephthalate; (c) 25-89 mol. per cent of a diaryl isophthalate; and (d) 1-5 mol. per cent of a diaryl carbonate (the sum of (b), (c) and (d) being substantially 100 mol. per cent) in the presence of a further 0.003-0.02 mol. of a diaryl carbonate per mol. of total aryl esters. Reaction is effected by heating to 180 DEG -310 DEG  C. in the presence of a catalyst (e.g. an oxide, hydroxide, hydride or phenolate of an alkali or alkaline earth metal; at ZnO, PbO or Sb2O3).

Abstract: 1,072,638. Noise making devices for toys. P. F. SEILLER. May 12, 1965 [Sept. 15, 1964], No. 19952/65. Heading G5J. The figure shows a noise making device for a toy. It consists of a basin-like member 2a with inwardly facing bumps 5 around its edge and a loose ball which strikes these bumps and causes the basin to sound as the device rotates. The ball is retained in position by a disc 4 attached to a hub 4a which passes through a central hole in the basin and which incorporates a groove 8 in which the basin is located. A central depression 6 is provided in the basin to throw the ball to the periphery of the basin and thus enable it to be used in other than a vertical position. In the embodiment shown, the retaining disc is made sufficiently large to serve as the wheel of a toy.

Title: Improvements in and relating to electronic mixer circuits for arithmetically combining two signals
IPC: H03C1/20
Filed: 1948-07-27
Abstract: 658,523. Valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). July 27, 1948, No. 20022. [Class 40 (vi)] In an arrangement for additively combining two signals by applying them to the respective control grids of a pair of valves having a common cathode resistance 8, undesired interelectrode capacity coupling between one control grid 6 and cathode 5 is neutralized by means of a condenser 24 connected between that grid and the anode of the other valve. As applied to a radar system for superimposing upon the reflected pulses 13 sinusoidal oscillations from a source 16, to give azimuthal angle indications on a plan position indicator, the two inputs are independently adjusted by means of potentiometers 9, 19, respectively, and the combined output is obtained across anode resistance 20. The arrangement is neutralized in order to prevent variation in the output obtained from the source 13 as the potentiometer 19 is adjusted, which otherwise occurs, being due to the signal transferred from the cathode 5 to the grid 6 via a potentiometer comprising the cathode to grid capacity and the impedance to ground presented by the lower part of the potentiometer 19.

Abstract: 1331817 Laminates JOHNSON and JOHNSON 19 April 1971 [26 Jan 1970] 20374/71 Heading B5N A laminated fabric having high bulk, a soft crumpled appearance and three-dimensional surface interest is made by forming a grid of intersecting filaments of a thermoplastic synthetic resin 14, said grid having potential shrinkage properties of at least 3% in each direction, placing a layer of fibrous material 12, 18 on one or both sides thereof, adhering the fibrous layers to the grid to form a laminate and heating the laminate to activate the potential shrinkage properties of the grid to cause it to shrink whereby portions of the layers of fibrous materials adhered to the grid and facing each other in the open areas of the grid become crumpled and buckled. The grid may be made of a polyethylene, especially high density polyethylene; polypropylene, preferably isotactic polypropylene; polyamides; polyesters or polyacrylics. The fibrous webs may be of cotton, rayon, polyamides, acrylics, monacrylics, polyester, polyolefin, cellulose ester, wool, mohair, silk fibres or tissue paper. The fibrous layer may have a film or sheet of polymer, e.g. polyester applied to its outer surface. In one embodiment fibrous webs 22, 28 and a plastics grid 24 are passed between pressure rollers 31, 32 to form a laminate and then through an apparatus 36 which rearranges the fibres to form a bundled fabric and mechanically intertwine and wrap the fibres around the filament of the grid. The laminate is then passed through an adhesive applying device 34 and then through a heater 35 where the adhesive is dried and the grid is shrunk. In another embodiment, adhesive 49 is applied to both sides of the grid 48 by passage through a part 50 and the grid is then laminated to fibrous webs 42, 44 before passage through the heater 60. A wide variety of binders are specified.

Filed: 1952-08-14
Abstract: A dusting powder having fungicidal and bactericidal properties comprises a finely divided cation exchange resin having carboxy groups as the functional groups thereof, said resin being dispersed in a powder base.  The resin may be prepared by co-polymerizing maleic anhydride and styrene in the presence of a cross-linking agent such as divinylbenzene, trivinylbenzene, ethylene diacrylate or diallyl maleate, fumarate or itaconate, or by co-polymerizing acrylic or methacrylic acid and a polyunsaturated polymerizable substance such as diallyl maleate, fumarate, or itaconate, allyl acrylate, allyl methacrylate, diallyl ether, ethylene dimethacrylate or divinylbenzene.  The powder base may comprise talc, starch, kaolin, zinc oxide or titanium oxide.  Metallic soaps such as zinc or magnesium stearate or laurate may be added to promote good dispersion and adhesion. Wetting agents for example alkaryl sulphomates, octylphenoxy ethoxyethoxy-ethyl sodium sulphonate, methylene bis (alkylphenoxypolyethoxyethanol), and octylphenoxy polyethoxyethanols, emolients such as a fatty glyceride or lanolin, and humectants, for example glycerine, may be present. Other substances which may be present are sulphur, calomel, sulphanilamide, boric acid, salicylic acid, ammonium chloride, phenol, undecylenic acid, oxyquinoline sulphate, N-a  pyridyl-N-benzyl-N1,N1-dimethylethylene diamine streptomycin and tyrothrycin.  The resin may be used to hold small amounts of basic materials, for example local anaesthetics or antibiotics having a basic group, and may be partially converted to salt form, for example the copper or zinc salt.  The resin may be a mixed sulphonic-carboxylic ion exchange resin and in this case the sulphonic group may be in salt form, for example the sodium, calcium, magnesium, copper or zinc salt.

Abstract: 821,976. Making radiators. USINES CHAUSSON S.A., DES. June 28, 1957 [July 18, 1956], No. 20538/57. Class 83 (2). [Also in Group XXX] A machine for positioning thin rectilinearedged elements, e.g. fins of cooling radiators at regular predetermined intervals, includes a supporting frame carrying at least one member formed as a screw and arranged to be rotatively driven about the axis of the thread thereof, there being movable means for carrying the elements and for engaging them in the thread. Radiator fins 14 assembled on a carriage 5 are engaged by rotating screws 23, 24, 25 having variable pitch threads 34 and constant pitch threads 31 which space the fins apart by the required amount corresponding to the pitch of the threads 31. When sufficient fins for charging a magazine have been taken by the screws, the first fin actuates a micro-switch to stop a motor 45 which drives the screws, through a chain 43 and chain wheels 35, 36, 37. While passing along the screws the fins are guided by a shutter 51 in its closed position. The shutter in opening about pivots 46, 47 rotates halfshells 59 and 60 which have grooves 63 corresponding with the pitch of the screw 31 so that the grooves engage the edges of the fins and form a guide, the fins being discharged, by pushing manually or mechanically in the direction f2, into a magazine adapted to receive and maintain them in spaced relation. If the fins are not quite perpendicular to the screw-axis when the motor stops, a spring-loaded pin 3, mounted on a flywheel 38 fixed to the screw 23, is withdrawn from the loose chain wheel 37 enabling the screw 23 to be rotated slightly to bring the fins into alignment. The fins may be supplied to the screws by a gravity-actuated carriage which is locked for loading by a pawl actuated by a lever. Guide plates 12 retain the fins in position on the carriage. Alternatively, an endless belt or conveyer may be used to carry the fins to the screws. The space between screws 23 and 24 may be varied to suit different sizes of fin.
