Patent GB-1072694-A (GB)
Title: Latex compositions
Inventor: SINGER REGINALD DAVID
IPC: C08F36/04
Filed: 1963-05-10
Abstract: A self-curing latex composition for backing carpets is produced by copolymerizing an ethylenically-unsaturated carboxylic acid with a diolefine and an alkenyl aromatic compound at a pH of less than 7 in the substantial absence of heavy metal ions, and, subsequently to polymerization, increasing the pH of the latex so obtained to a value greater than 7.  Monomers exemplified are itaconic acid, acrylic acid, butadiene and styrene; others specified are methacrylic acid, isoprene and a -methyl styrene. The polymerization is effected in aqueous emulsion with potassium persulphate as the catalyst and in the presence of a sequestering agent, an emulsifying agent, a pH buffer and tertiary-dodecyl mercaptan.  After polymerization, ammonia is added to adjust the pH.  A composition was produced by incorporating in the prepared latex an aqueous paste of whiting and sodium hexametaphosphate, an antioxidant dispersion, and a solution of sodium polyacrylate as a thickener.ALSO:A self-curing latex composition for backing carpets is produced by copolymerizing an ethylenically-unsaturated carboxylic acid with a diolefin and an alkenyl aromatic compound at a pH less than 7 in the substantial absence of heavy metal ions, and, subsequently to polymerization, increasing the pH of the latex so obtained to a value greater than 7.

Abstract: 1,011,817. Distributing television. TELEGLOBE PAY-TV SYSTEM Inc. May 17, 1962, No. 19093/62. Addition to 844,118. Heading H4R. In a television distribution system using wireless video signals and wire-transmitted audio signals as in the parent Specification, the supply of the audio signals when required by a subscriber is effected through a telephone switching network which also meters the supply to the subscriber. As shown, the wireless video signals reach the receiver 13 from the transmitter 11 and may be accompanied by an un-related audio signal. The synchronized audio signals are transmitted by line 15 through the switching network 16 and control unit 17 to the separate speaker 18. The subscriber indicates his wish by telephoning the switching network 16, or dialling a number code or actuating a separate, e.g. push-button operated, circuit. The switching network then sends a distinctive signal to actuate the control unit 17, e.g. by exciting a resonant circuit therein, to switch the audio signal to the speaker. At the same time the metering-unit 21 is started. An additional unit may be inserted in the line 15b requiring to be actuated by the subscriber by the insertion of a coin or token. Alternatively a scrambler may be inserted in the line 15 and an unscrambler in the line 156. The communication between the subscriber and the network 16 may be by way of a second telephone exchange.

Title: Improved apparatus for automatically balancing and measuring forces
IPC: G06G3/00
Filed: 1953-07-13
Abstract: 725,494. Dynamometers; calculating-apparatus. SORTEBERG, J. July 13, 1953 [Aug. 26, 1952], No. 19387/53. Classes 106 (1) and 106(2). A force measuring or a multiplying, dividing and square root determining apparatus comprises two weighbeams 13 and 15, Fig. 5, means for transmitting a force A, B, C and D to each end of said weighbeams 13 and 15, a movable fulcrum F1, F2 for each weighbeam, said fulcrums F1, F2 being in fixed relationship to each other to move in unison along their weighbeams, means for automatically moving the fulcrums F1, F2 to balance the moments on one weighbeam, and means for automatically balancing the moments on the other weighbeam by changing the force transmitted to one end of such weighbeam. It can be shown that, for balance, A Î B = C Î D. Hence, if three of the forces are known the fourth can be determined. As shown in Fig. 1, the forces A, B, C and Dare applied to the weighbeams 13, 15 through rods 19, 22, 25 and 28 by flexible bellows 17, 20, 23 and 26. The weighbeams 13, 15 are suspended by leaf-springs 14 and 16. The weighbeams are spaced by rollers 8 and 9 comprising the fulcrums F1 and F2, the rollers 8 and 9 being housed in a rod 3 vertically displaceable in response to a dontrollable pressure acting on a flexible bellows 5. Assuming that the system is balanced, let the pressure applied to the bellows 17 change. This will upset the balance of weighbeam 13 with the effect that a weighbeam extension 31 will move either towards or away from a nozzle 30, increasing or decreasing, as the case may be, the back pressure transmitted to the bellows through a passage 32. Bellows 5 will reposition the rollers 8 and 9 (fulcrums F1 and F2) until balance is restored on weighbeam 13. The movement of rollers 8 and 9 will simultaneously upset the balance of weighbeam 15 with the result that its extension 35 will move towards or away from the nozzle 34 as the'case may be. This in turn will increase or decrease the back pressure transmitted to bellows 20 through a passage 36 until balance of the weighbeam 15 is restored. For square-root extraction, the functioning is essentially as above described except that the pressure on the bellows 17 is made the same as that on the bellows 20 at all times by means of an interconnecting tube 37 as shown in Fig. 3. If a connection is made between the bellows casings 24 and 27 by a passage 38, see Fig. 4, the above equation becomes C<2> (or D<2>)= A Î B, provided that the area of the bellows 23 and 26 are identical. For chosen values of C (or D) the product A Î B equals a constant. This is the equation for an equilateral hyperbola.

Abstract: 793,635. Coating by vapour deposition. ENGLISH ELECTRIC VALVE CO., Ltd. May 2, 1956 [July 6, 1955], No. 19580/55. Class 82(2) [Also in Group XL(a)] A thin film is made by subjecting a specimen of the material of the film supported by one pole-piece of a magnet to an electron beam which is emitted by a gun in the other pole-piece and which is constrained to follow the magnetic flux path, the electronic bombardment causing evaporation of the material, the resulting evaporate being condensed on a substrate which is clear of the flux and beam path. The material may be a refractory insulator, e.g. alumina, magnesia, silica, or zirconia, and the procedure is carried out in vacuo. As shown, pole-piece 2 of permanent magnet 1 supports the material 3 to be evaporated, the other pole-piece 4 comprising a hollow section 5 within which is contained an electron gun consisting of cathode 7 surrounded by control grid 8. Electrons from the gun emerge through orifice 9 and follow the trajectory 6a, being bent through 90 degrees, to strike material 3, evaporate from which condenses on surface 14. The material 3 may be moved so as continuously to bring fresh areas thereof under bombardment. The evaporation of glass is also referred to; free supporting glass films may be made by the process described in Specification 709,503 [Group XXIII].
