Patent GB-386439-A (GB)
Abstract: 386,439. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and LIMB, F., Holmwood, Fellows Road, Beeston, Nottingham. Jan. 14, 1932, No. 1114. [Class 106 (i).] Bets of different kinds (e.g. win and place) may be laid simultaneously on the same competitor and a single ticket issued. In the arrangement shown depression of a competitor's key, say B2, closes circuit to a relay H at the central station to prepare, at h1, h2, the circuit of that competitor's win and place registers IW, IP. The kind of bet is set up at keys PB, WB or EW, wired through sequentially controlled contacts a2, a3, and in multiple with other machines to relays W, P serving to close circuits at w2, p3 for the total registers TW, TP. When the total and competitor registers operate, their contacts complete a line through a1 and keyboard contact u to the relay T to initiate the ticket-issuing operation. If key EW is used relays P and W both operate and cause energization of both sets of registers, the contacts tw2, tp2, ip2 and iw2 of which, together with operated contacts p1, w1, complete the line for the revertive signal to the relay T. The closure of the contacts a1, a2, a3 may be controlled by a relay chain ; a relay ST in series with relay T operating when a bet is set up to prepare for the eventual closing of the contacts. When the revertive signal line is completed it short cirucits relay ST and causes relay T to operate. In modifications suggested, the EW key may be provided with its own line to energize a relay at the central equipment for causing operation of the win and place registers, each ticket machine may be allotted to the receipt of not more than two classes of bet, and there may be two ticket-issuing mechanisms for one set of competitor keys, each mechanism issuing only win or place tickets. An arrangement similar to that shown is also described for use with straight, place and show bets. Specification 367,488 is referred to.

Abstract: 1,254,024. Drying glass fibre strands. PPG INDUSTRIES Inc. 1 Aug., 1969 [2 Aug., 1968; 2 June, 1960], No. 38655/69. Heading F4G. Glass fibre strands are dried on packages 26 in a vacuum chamber 32 at reduced pressure and elevated temperature. Initially the packages 26, mounted on rack 31 having air float supports, or on truck 34 having roller support, are heated at atmospheric pressure by steam heated pipes 46 for twenty to thirty minutes, after which the pressure is reduced by vacuum pump 38 during a similar time. A vacuum pressure measuring device 50 is provided and the degree of pressure rise in chamber 32 as measured by 50 when the pump 38 is switched off, gives a measure of the remaining moisture in the packages, so that the drying can be terminated when a desired moisture level is attained. Uniformity of drying through the package is achieved by this method. The vacuum is approximately 27  inches of mercury below atmospheric. Temperatures in the range 150-270‹ F. are used.

Title: Manufacture of hardened products from epoxy compounds
IPC: C08G59/42
Filed: 1956-12-21
Abstract: The hardening of epoxide resins by the usual polycarboxylic acids, amines, &c., is accelerated by the addition of 1-2% by weight (based on the combined weight of resin and hardener) of an organic sulphur compound which is not a vulcanisation accelerator for rubber and in which the sulphur is not a member of a ring and which contains at least one mercaptan sulphide, or sulphoxide group, e.g. monothioglycol, dithioglycol, b -thiodiglycol, thiodiglycollic acid diethyl ester, diphenyl sulphide, thiophenyl-2-carboxylic acid, or dimethyl sulphoxide.  The accelerators reduce both hardening times and temperatures.  They may be used with casting resins, coating compositions or adhesives.  Conventional additives, e.g. silica, dyestuffs, pigments, plasticisers, reinforcing materials or other resins may be included.  Various phenol which may be used for making the epoxy resins are mentioned and many known hardeners for the resins are listed.  Comparative examples illustrate the accelerating effect of b -thiodiglycol or mixtures of the diglycidyl ether of 4, 41-dioxy-diphenyl-dimethyl-methane with phthalic or maleic anhydride and with hexamethylene tetramine.

As shown in Figs. 1 and 2, the loops S 1  and S 2  are provided in respective cables 22, 24 and include detectors D 1  which open in response to burglars or fire. In the normal state the potentials at points b and d are such as to maintain the transistor T 1  non-conductive but in the event of interruption of one or other or both the loops S 1 , S 2 , these potentials are such as to render the transistor T 1  conductive which causes energization of a LED D and the application of a signal on line 34 to an indicator or alarm device. To enable detection of short circuiting between the two conductor loops, the transistor T 1  is replaced by a self-conducting MOSFET, Fig. 4 (not shown). In this embodiment, the resistors R 11  and R 21  may be omitted, Fig. 3 (not shown). The embodiment of Fig. 4 may be further modified by providing a resistor (R 13 ) between point a and terminal 10 and a resistor (R 23 ) between point c and terminal 12, Fig. 5 (not shown). Fig. 6 shows a further modification of this embodiment in which a short-circuit current limiting resistor R K  is provided as well as a transistor T 3  and relay R, transistor T 3  causing energization of relay R to close contact K in an alarm circuit when one or other or both of the loops are open-circuited or when adjacent loops are short-ciruited. Figs. 7-10 (not shown) show various arrangements of loops in a single cable as well as positions of various detectors which may be ionization fire alarms or photoelectric fire alarms.

Keratinous fibres, e.g. fibres taken from the skins of sheep, goats, llamas, vicunas and alpacas, alone or in admixture with polyester, polyamide or polyacrylonitrile fibres, are shrink-proofed by treating them with ozone and a polymer. The fibres which may be in the form of loose fibres, slivers, tow or fabrics may be treated with the ozone at 20‹-100‹C in the presence or absence of moisture but preferably while they contain 5-40% by weight of water for 0.5-5 minutes. The ozone is preferably applied in the form of a gaseous mixture which is preferably a mixture of ozone and steam when application is at an elevated temperature. Treatment with the polymer may be effected either by polymerising a polymerisable substance in the presence of the treated fibres or by impregnating the treted fibres with an aqueous solution or dispersion of the polymer. Suitable polymers are polyethyleneimine condensation products of polyamides and epichlorhydrin, polyolefins and polyacrylates. 0.5-10% by weight of polymer may be applied and curing may subsequently be effected in the presence of an acid catalyst, e.g. ammonium chloride, oxalic acid, magnesium chloride, sulphuric acid or zinc nitrate, after impregnation and drying, in a drying machine, in a semi-decater or by passage through metal rollers heated to 150‹-400‹C. The fibres may be used in the manufacture of upholstery and carpets.
