Title: Glass and Other Light-Transmitting Materials
IPC: B32B7/027
Filed: 1966-01-25
Abstract: 1,152,691. Protective screens. GLAVERBEL. 25 Jan., 1966 [23 March, 1965; 21 Oct., 1965; 11 Nov., 1965], No. 3354/66. Heading ASA. [Also in Divisions ,C1, C4, C7, E1 and H4] . A light transmitting material or article comprising (a) a light transmitting layer which has, or which under sufficiently intense incident light or heat radiation temporarily acquires heat absorbing properties, and (b) a light transmitting layer which is, or which is capable of temporarily being rendered radiant heat reflecting and is dispersed so that it can protect layer (a) from radiant heat rays. The layers may be self-supporting layers or sheets or layers applied as a coating to self-supporting sheets which may be of glass or plastics material. The protecting layer (b) may be a coating of a metal, a metal-containing compound 01 01- a metalloid deposited directly on to the protected layer (a) or on a sheet of material which is then secured to the protected layer. Preferred coatings are of gold, silver or titanium oxide..In one form of the invention the protecting layer is sandwiched between two glass sheets, bothof which 'may be coloured,' the sheets being bonded together either by soldering at their marginal edges or by an inter-layer of plastics material e.g. polyvinylbutyral. In another form the material may constitute a double glazing unit, the protecting layer being on the outer or inner surface of one of two spaced sheets which are-secured together by a continuous metal strip soldered to copper bands deposited on the inner marginal edges of the sheets. Another form of protecting layer consists of a thin layer of a metal or semiconductor the radiant-heat reflecting properties of which can be varied by the application of an electric field. The intensity of the applied field can be controlled by means of a photoelectric cell actuated by sunlight. The protected layer may be of coloured glass (see Division C1 and may be chosen to be neutral in relation to the protecting layer. Thus, e.g. a protecting layer of gold or titanium oxide may be associated with a layer of grey glass. Alternatively the protected layer may be a phototropic layer. One such layer consists of calcium butyrate incorporated in an agar binder. This layer may be applied to a sheet of glass which is itself coloured. Other substances which may constitute a phototropic layer include polyvinyl methyl ether, alkalineearth salts of polyacrylic acid, polymerised polyvinyl partial acetals or cetals of which the ether oxygen atoms are associated with water, and hydrated salts. Still further phototropic layers comprise a light-sensitive halogenides to which halogenides of copper, cadmium or nickel may be added as catalysts. In one example of such a layer a coating containing equal parts of AgCl and AgBr is applied to a colourless glass sheet and coated first with a layer of SiO and then with calcium silicate. The material may be used for glazing or for making protective shields.

Title: Automatic digital controller
IPC: G05D7/06
Filed: 1966-01-26
Abstract: Mouldings comprising a consolidated integral mass of acrylonitrole co-polymer fibres e.g. co-polymers or ter-polymers of 85% acrylontrile with methylmethacrylate or vinyl acetate alone or to which may be added phenolic resins, are produced by melting the fibres e.g. in the form of yarn, tow consisting of parallel continuous filaments, chopped tow, one or more pieces of woven, non-woven or knitted fabric, felt or tape, with an organic solvent, e.g. dimethylformamide, ethyl carbonate or dimethyl sulphoxide, preferably together with at least 25% of a volatile solvent e.g. dichloromethane or diethyl ether, and heating the fibres to reduce the solvent content thereof to 75% to 80% by weight of the unwetted fibres prior to applying heat to plasticise the fibres which are then moulded and cooled under pressure before removal from the mould for susequent removal of residue solvent by drying at ambient temperature or, when heated to 50 DEG C, in an air stream or under vacuum.  The impregnated fibres e.g. when wound as yarn containing 75-85% solvent onto a core, are heated between the platens of a moulding press at 60-110 DEG C to a temperature sufficient to cause some plasticisation prior to applying a light moulding pressure e.g. for 5 minutes followed by full moulding pressure e.g. 8,000 p.s.i. for 15 minutes when the bulk of the solvent is expressed and the moulding is removed from the mould after cooling to 40 DEG C.

Abstract: 607,442. Valve generating circuits. PELLE, P. Feb. 4, 1946, No. 3523. Convention date, Feb. 15, 1945. [Class 40 (vi)] In a blocking oscillator, means are provided to apply a negative potential to the grid of the valve, so that on removal of this potential, oscillations commence after a time delay period. Fig. 3 shows a blocking oscillator circuit, a negative potential being applied to the grid of valve L via the contact of relay A. When relay A is released in response to external control, the blocking potential leaks away as the grid condenser-resistance circuit discharges, and oscillations commence after a time delay. More than one oscillator may be simultaneously controlled by the use of a plurality of relay contacts, or alternatively by the use of more than one relay. The control and screen grids of a pentode valve may be used to form the oscillator circuit.

Title: Improvements in and relating to the cooling of internal combustion engines
IPC: F02F1/36
Filed: 1943-03-09
Abstract: 563,789. Cooling cylinder heads. WATTS, L. D., HUGH, P. G., NORTH, O. D., and SCAMMELL LORRIES, Ltd. March 9, 1943, No. 3795. [Class 7 (ii)] An internal-combustion engine has a distributer plate fitted within the cylinder head jacket close to the surface to be cooled, the plate being provided with openings arranged so that the coolant flow is directed around selected parts such as plug apertures, valve-stem guides, and exhaust passages and hot spots are eliminated. In the application to a side-valve engine, Figs. 1 and 3, a detachable head 5 secured by bolts 6 to the cylinder block 1 is closed on its upper face by a separate cover-plate 9 and packing 10, the cover-plate being secured by bolts 14. Flow of coolant from the cylinder jacket 2 passes to the head through apertures 18, 19. Flow in the head is controlled by a distributer plate 20, 27 secured to the coverplate by screws 24 arranged to provide shallow passages 22 for flow over the combustion chamber. Apertures 29 in the plate permit flow. round the spark plug bosses 12 into a space enclosed by a wall 23 on the plate. From this space flow passes to the radiator through a pipe 30. The invention is applicable to engines having either thermo-syphon or pump circulation: The increased speed of flow induced by the distributer plate reduces the formation of deposits in the cooling system. In the application to an overhead valve engine, Fig. 6, the head is in two sections 46, 47 separated by a joint 48. The lower section which forms the combustion chamber 49 is fitted with a distributer plate 54 which directs flow round the valve ports and spark-plug bosses. A second plate 60 between the head sections directs flow to the valve guide and thence to the outflow pipe 63. The push rods pass through tubes 66. In another modification, for a side-valve engine, the distributer plates may be one-piece sheet metal pressings.

Anthropometrical appliances.-In apparatus for measuring and recording muscular reaction times or psychomotor response wherein electric lamps or other visual indicators set in action by a tester are switched off by the subject under test, the switch or switches operated by the subject are so connected with the lamp &c. circuits as to determine which of the lamps &c. are in operation at the commencement of and during the test. For testing the aptitude of a pilot for Bying the apparatus comprises a series of coloured lamps 4 in circuit with a tester's switch 17 and a metal arm 2 engaging contacts 3 and controlled by a rudder bar 1, and a series of coloured lamps 10 in circuit with a tester's switch 16 and with platinum contacts 9 in an arcuate tube 7 containing mercury 8 and controlled by a control stick 6. The initial position of the controls 1, 6 determines which of the lamps 4, 10 are lit up when the switches 16, 17 are closed. The operation to be performed by the subject under test is to centralize the controls so that none of the coloured lamps remains in operation. White lamps 5, 11 are in a separate circuit and remain lit. A record of the time the lamps 4, 10 are in operation is obtained by means of an electrically controlled clock 14 and tape machine 15 which are arranged in a circuit which is closed by a relay 12 when current is passing in the lamp circuits. If the pilot over-shoots the central position this is indicated on the record of the tape machine. In modifications, the control stick 6 can rotate in more than one plane, and more than one arcuate tube may be used, or the arcuate tube may be replaced by a pendulum device coacting with contacts moving with the control stick.
