Title: Improvements in power supply arrangements suitable for use in telephone systems
IPC: H04M19/00
Filed: 1937-09-21
Abstract: 502,800. Exchange systems. POLLAK, J. E. (Associated Telephone & Telegraph Co.) Sept. 21, 1937, No. 25639. [Class 40 (iv)] [Also in Group XXXV] Low-voltage D.C. 'supply in a telephone system is provided by a unit operable from either A.C. or D.C. commercial supply mains S by alteration of connections on a terminal board whereby the primary of a transformer T which feeds a rectifier is connected either directly to A.C. mains or by means of a vibrator PC to D.C. mains. Varying mains voltages are provided for, connections at the terminal board for D.C. and A.C. being shown in Figs. 2 and 3 respectively. The transformer has two secondary windings, one K, M being connected over rectifying and smoothing equipment to the D.C. supply terminals of the telephone system, whereas the other, E, J, is used to provide ringing current. Relay RD is operated when the load is heavy, e.g. in inter-exchange calls, to shunt out resistance R10 which is normally in circuit for D.C. mains operation. To prevent noise, the vibrator is resiliently mounted in a solid metal casting, e.g. of aluminium, providing adequate heat dissipation.
Patent GB-256664-A (GB)
Abstract: 256,664. Dreyfus, H. April 9, 1925. Acetic anhydride is prepared by passing the vapour of acetic acid of high concentration over heated anhydrous catalysts which normally promote the formation of acetone, the reaction being performed at a temperature insufficiently high to produce acetone. Catalysts mentioned are oxides or carbonates of metals whose acetates yield acetone on pyrogenic decomposition, e.g. barium carbonate, calcium carbonate, zinc oxide, and tin oxide, zinc dust, finely-divided cadmium, aluminium, lead and iron, and iron turnings, The reaction temperature varies from 300‹ C. or below to 500‹ C., whilst ordinary or reduced pressure may be employed. The reaction vapours are preferably subjected to fractional condensation on leaving the reaction zone, as described in Specification 256,663. The concentration of the acetic acid used should not fall below 90 per cent., and the speed of passage of the vapours is regulated to avoid decomposition into gaseous products occurring at low speeds. Examples are given.

Abstract: 271,716. Wheelock, J. Oct. 15, 1926. Alarms operated by fusible devices.-In a push-button, for an electric call-bell circuit, modified to act as an automatic fire-alarm, the button 1 is bored out centrally to accommodate the stem 2 of a flat plate 3 normally hedd stationary by a block 5 of readily fusible holder exposed at the outer surface of the button. When the solder melts, the plate 3 is moved rearwardly by a spring 8 to close the bell circuit. In a modification, the solder is in the form of a pin passing through the stem 2. A disc may be mounted on the front of the button to distinguish it from buttons of ordinary type, and this disc may be painted with luminous paint.
Patent GB-587309-A (GB)
Title: Improved process for the production of extensible contractile tubular, annular or the like film products
IPC: C08L1/12
Filed: 1939-09-13
Abstract: Bottle caps, rings and like tubular film products having a basis of cellulose triesters, such as cellulose triacetate, are formed by a wet-forming process at ordinary temperatures and are impregnated while in the gelatinous state with a mixture of (a) triacetin with (b) a mono-or diester of glycol derived from a lower fatty acid, particularly glycol monoformate, monoacetate or diacetate or with (c) a derivative of glycol or glycerine in which one OH group of the glycol or glycerine molecule is replaced by halogen and which contains a second free OH group or a second OH group replaced by a methoxy or ethoxy radicle.  The impregnated film products can be stretched while still moist, but shrink when dried.  The impregnation may be effected by dipping the film product into the mixture after coagulation or by incorporating the mixture in both the film-forming solution and the coagulating bath.  Synthetic resins, such as polyvinyl esters, polyvinyl formals or esters of polyacids and polyalcohols, may be incorporated in the cellulose ester film-forming solution.  In examples: (i) bottle caps of cellulose triacetate formed by a wet-forming process at ordinary temperatures are impregnated while in the gelatinous state with an aqueous triacetin solution containing glycol monochlorhydrin or glycol diacetate, and (ii) film products are obtained from a solution of cellulose triacetate in a mixture of glycol monochlorhydrin, water and triacetin employing a coagulating bath consisting of a more dilute aqueous solution of glycolmonochlorhydrin and triacetin. Specification 477,403 is referred to.  The Specification as open to inspection under Sect. 91 refers to a process for the manufacture of bottle caps, rings and like tubular film products having a basis of cellulose derivatives insoluble in water in which the formed articles are impregnated while in the gelatinous state with an ester of glycol or of glycerine in which one OH group of the glycol or glycerine molecule is esterified by either a lower fatty acid or is replaced by a halogen and which contains a second free OH group or a second OH group esterified by a lower fatty acid or replaced by a methoxy or ethoxy radicle.  It is stated that the impregnating agent is preferably associated with ordinary plasticising agents of cellulose derivatives.  This subject-matter does not appear in the Specification as accepted.

Title: Automatic Air and Electric Railway Car Coupler
IPC: B61G5/06
Filed: 1967-06-06
Abstract: 1,180,287. Railway couplings. WESTINGHOUSE AIR BRAKE CO. 6 June, 1967 [27 June, 1966], No. 26048/67. Heading B7T. [Also in Division H2] An automatic railway car coupler comprises a mechanical latching portion 1 including a guide pin 5 and a gathering bore 7 with latch 8, a pipe connecting portion 3 and an electrical connecting portion 4 bolted to the underside of portion 1, the portion 4 consisting of a multiplecontact unit 23 mounted on a plate 24 longitudinally slidable in casing 13 on rails 26, said unit being biased by coil springs 29 to a position where it projects outwardly from the front of casing 13. When the coupler is not connected to a similar coupler the casing front is closed by a plate 42. A spring loaded shaft 34 acts, via a finger 37, to bias plate 24 towards the rear of the coupler. When two couplers engage they are located and connected by their respective pins 5 and bores 7, and pistons 48 of each coupler are forced inwardly by contact with a plate 51 on the other coupler causing, via linkage 53, 54, 56 and 57, the plate 42 to slide under the coupler as shown in phantom lines in Fig. 5. The plate 42 has pins 46 which are guided in slots 47 during the sliding. The units 23 on contacting one another are then forced into casings 13 against springs 29 until they engage one another. The units 23 may be disengaged while the couplers are still mechanically engaged by rotating a shaft 34 using a rod 36 insertable in socket 35 at the base of the shaft. The rod 36 may be engaged behind a retractable projection 74 to prevent the spring loading on shaft 34 returning the unit 23. When the couplers are disengaged by drawing them apart this tensions the spring loading on shaft 34 causing the units 23 to separate with a snap action which minimizes arcing between the contacts. The plate 42 recloses the casing 13 by a spring 65 acting through the linkage 53 &c. When the coupler is disengaged a switch 71 closes the circuits through it and when engaged mechanically but not electrically with a similar coupler the circuits through it may be completed by a further switch.

Title: Method and apparatus for bonding together pieces of Sheet Material
Inventor: HACKER KURT
IPC: B29C65/48
Filed: 1967-06-06
Abstract: 1,166,147. Seaming non-metallic sheet material; laminating. FORTUNA-WERKE MASCHINENFABRIK A.G. 6 June, 1967 [7 June, 1966; 23 June, 1966; 28 April, 1967], No. 26055/67. Headings B5K and B5N. [Also in Division A3] A method of bonding together pieces of sheet material, e.g. leather shoe uppers 6a and toe caps 6b, in superposed relationship by interposing a heat activated adhesive between the superposed pieces and then subjecting them to heat and pressure includes the steps of subjecting the superposed pieces to successive partial bonding stages, the pieces being moved from one bonding zone to another whilst fresh pieces to be bonded together are moved into the first bonding zone and completely bonded pieces are removed from the last bonding zone during the intervals between successive bonding stages. Apparatus for performing the method includes an intermittently rotating work support 5 and a heated press-plate 4. As described, the apparatus performs two partial bonding operations, the support 5 being divided into four zones: a loading zone A, two partial bonding zones B, C, and an unloading zone D, the support 5 being rotated through 90 degrees between each partial bonding operation. In order to prevent the workpieces sticking to the heated press-plate 4 the workpieces 19 may be clamped to the supports 5 (Fig. 4), by spring-loaded pins 17 having heads which grip the edge of the workpiece 19 and which are raised in the loading and unloading zones A, D by a cam 10. The surfaces of the support 5 and press-plate 4 may have a covering of plastics material, e.g. silicone rubber, having the following properties;-(a) resistance to bonding pressures and temperatures, (b) resilience in the range above 40 D.V.M. points of softness (below 70 Shore), (c) disinclination to enter into a firm bonding with actuated bonding adhesives, and (d) a thermal conductivity which permits a bonding time equal to, or only slightly exceeding, that attainable with a metal heating surface.
