Title: Copolyester adhesive
IPC: C08G63/181
Filed: 1964-09-02
Abstract: A copolyester adhesive is made by reacting a diol component at least 80 mol per cent of which is a butane diol and the remainder of which is preferably an alkanediol containing 2-10 carbon atoms with an acid component consisting of (a) 25 to 60 mol per cent terephthalic acid (or a dialkyl ester thereof), (b) 15 to 65 mol per cent isophthalic acid (or a dialkyl ester thereof), and (c) one or more saturated aliphatic dibasic acids (or dialkyl esters thereof) containing 6 to 36 carbon atoms and in an amount by weight equal to the weight of 5 to 25 mol per cent of sebacic acid.ALSO:A shoe sole is adhered to a shoe upper by coating a strip along the periphery of the surface of the sole which is to be placed next to the shoe upper with a certain copolyester adhesive, treating the adhesive layer on the shoe sole to render it tacky (e.g. with an infra-red lamp, a radiant heater or a solvent), positioning the shoe sole on the shoe upper with the activated copolyester in contact with the shoe upper and pressing the shoe assembly in a press.  The copolyester is one of (a) a diol component at least 80 mol per cent of which is a butanediol (b) terephthalic acid (c) isophthalic acid and (d) a C6-C36 aliphatic saturated dicarboxylic acid (especially sebacic acid) (see Division C3).  The shoe sole may be made of natural rubber and/or styrene-butadiene rubber, or a vinyl chloride/vinyl acetate copolymer.  Before coating the copolyester on the sole, the latter may be primed with a mixture of a butadiene-acrylonitrile copolymer and a butylphenol-formaldehyde resin.

Abstract: Lubricating oil compositions contain as extreme pressure agent an oil-soluble reaction product prepared by reaction of a chloroalkyl phosphite and an overbased alkaline earth metal salt selected from a sulphonate (e.g. petroleum or aromatic sulphonate) and a phenate. Suitable oils are mineral oils, synthetic ester lubricants and polymer lubricants.  The complexes may be combined with detergents, viscosity index improvers, antioxidants and antifoamers.ALSO:An oil-soluble reaction product is obtained by reaction of a chloroalkyl-phosphite and an overbased alkaline earth metal salt selected from a sulphonate and a phenate.  The reaction is accomplished by mixing the reactants and heating them, preferably at a temperature between 50 DEG  and 95 DEG  C., until a homogeneous solution is obtained.  Suitable chloroalkylphosphites include the mono-, bis-, and trichloroalkylphosphates where the alkyl group may contain from 1 to 20 carbon atoms, and the chlorine atom is preferably attached to the a - or b -position of the alkyl radical. The phosphites may contain mixed alkyl groups.

Title: Improvements in or relating to coating objects with light-absorbing transparent or translucent colour layers
IPC: C03C17/245
Filed: 1962-09-26
Abstract: A selectively light absorbing coloured, transparent or translucent layer is formed on a substrate by simultaneously vapour depositing at least two substances comprising one or more organic compounds which are either coloured or decompose or dissociate to form a coloured compound, and an inorganic substance such as silicon monoxide, cryolite, magnesium fluoride and titanium dioxide.

Abstract: 620,068. Feeding sheets. BACKHOUSE, H. T. Dec. 11, 1946, No. 36637. [Class 100 (i)] In sheet feeding apparatus of the kind in which separation of the sheets from a pile 2 is effected by a reciprocating suction or other gripper 1 acting on the rear edge of the pile, and double feed is prevented by a reciprocating presser 4, the pressure of the member 4 is controlled by means which continuously increase its pressure, or increase its pressure by one or more steps. The member 4 may be formed with means for delivering an air blast under the separated sheet, and the edge of the pile may be acted upon by an air blast to facilitate separation of the sheets, and the separated sheet is advanced bv known means such as those described in Specifications 427,041 and 475,892. The presser 4, Fig. 1, is controlled by a cam 9 on a shaft 10 which first permits a spring 13 to press on a lever 7 and force the presser on to the pile. Subsequently the cam 9 rotates a lever 17 connected by a link 16 to a sliding abutment 15 which acts on the spring 13 so as to increase the pressure on the lever 7. In Fig. 2 the shaft 10 is fitted with a second cam which acts upon a lever 23 connected to an extension spring 24 subsequent to the action of the spring 13, which initially presses the member 4 on to the pile.

Abstract: 1363135 Channel selection for radio or TV receivers LOEWE OPTA GmbH 4 Aug 1971 [14 Aug 1970] 36699/71 Heading H3Q In a channel tuning arrangement for radio and television receivers with predetermined channels sequentially selectable by the application of pulses generated in response to manual actuation either of one of a plurality of information transfer devices, each associated with a channel and each mounted on the receiver or of a remote control device, the start/stop information is given by the actuated information transfer device or by the beginning and end of a remote control signal generated on manual actuation of the remote control device and the pulse period of the pulses caused to be generated on actuation of the remote control device is substantially greater than the pulse period of the pulses generated in response to actuation of any of the information transfer devices. In the preferred embodiment the channel selection on the receiver provides-a rapid pulse sequence where the pulse period of these pulses is less than 200 ms. The information transfer devices may be a series of push-buttons or touchsensitive devices as mentioned below. The remote control channel selection is slower with the start information given by the beginning of the remote control signal and the stop information given by the end of this signal. The pulse period of the pulse train generated in response to the remote control signal must be sufficiently long that the desired channel can be read on an indicator such as a numerical display tube and the remote control signal can be promptly interrupted. The pulse period of such a pulse train should be at least 500 ms. The introduction of the Specification refers to known channel selection by (a) variable capacitance diode circuit, the channel selection being effected with the aid of pre-set potentiometers, the channel changeover being made electronically by semiconductor devices such as diodes or transistors and by the contact resistance of a human finger touching two contact surfaces, changeover being done at the touch by a flip-flop circuit associated with each channel.

Abstract: 893,174. Liquid fuel fired furnace. JONES GAS PROCESS CO. Ltd. Oct. 28, 1960 [Nov. 3, 1959], No. 37223/59. Drawings to Specification. Class 51 (1). The emissivity of the flame in a furnace is increased by manufacturing free carbon entrained in hot gas close to the furnace combustion zone and feeding the gas and entrained carbon to the combustion zone where the carbon is burned. The carbon is formed by the thermal dissociation of a hydrocarbon fuel which may be the same fuel as that used to heat the furnace. A refractory chequer-work reaction chamber is heated by the combustion of a hydrocarbon fuel in one stage, and the fuel is dissociated in a second stage by the heat of the chequer-work. The waste gases produced in the first stage may be fed to the furnace or led away. To produce a continuous supply of carbon, two or more reaction chambers may be arranged to work cyclically. The inoperative reaction chamber of a pair arranged to work cyclically may be heated by the combustion of carbon deposited during a previous cycle, and the waste gases passed to the operative reaction chamber of the pair. Separate inlets may be provided for the heating fuel and the fuel to be cracked. In another embodiment, liquid fuel is partially burnt in a subsidiary combustion chamber to provide the flow of carbon in hot gas. The hot gases and the entrained carbon may be fed to the combustion zone of the furnace at several points along the length of the flame. The particle size of the carbon fed into the combustion zone is between 25 millimicrons and 1 micron, with an average size of ¢ micron, and the temperature of the gases and carbon lies between 800-1700‹ C.
