Title: Improvements in automatic and semi-automatic telephony
IPC: H04Q3/00
Filed: 1925-06-30
Abstract: 258,939. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), Moir, R. A., and Hartley, G. C. June 30, 1925. Semi automatic exchange systems.-In a relay group which controls the association of a coder with the outgoing end of an automatic-tomanual trunk, the relay which is energized when the sending of code impulses is completed earths the test conductor and locks up over this earth so that a trunk which is faulty at its manual end will be held busy at its outgoing end. When battery and earth are returned at the manual end a relay bridged across the trunk is operated to complete a metallic connection through the relay group and to release the firstmentioned relay. The relay group shown comprises four relays only. Normal operation. When an outgoing trunk is seized, relay A operates and completes the usual hunting circuit for the coder selector by connecting magnet DM over contacts K 6, A 6, K 26 to the test wiper. When an idle. coder is found. relay K energizes in series with magnet DM and reverses the connections of relay A to the incoming line wires thus causing the registercontroller (of the code-translating type) to send out the numerical impulses which are repeated to the coder over a circuit including the lowest (off-normal) wiper of the coder selector, contacts A 6, K 6, and the fourth (pulse-wire) wiper of the coder selector. When code transmission is completed, earth sent back from the coder over the pulse wire energizes relay CZ which releases relays A, K, earths the incoming test conductor over contacts CZ 5, and locks up over its lefthand winding and contacts CZ 17, CT 7 to this earth. The circuit through the right-hand winding of relay CZ, contacts CZ 8, CT 11, the incoming talking loop, and contacts CT 15, CZ 11 gives a supervisory signal if the call originates at a manual position. When battery and earth are connected to the outgoing conductors at the manual exchange, relay CT energizes over its bridged left-hand winding, releases relay CZ, completes a through metallic connection and locks over its right-hand winding to the incoming test conductor which is earthed at a preceding selector. Faulty trunk. If batterv and earth are not returned from the manual end, the earth at the contacts CZ 5 holds the trunk permanently busy and the continued energization of relay CZ causes a supervisory relay in series therewith to sound a delayed alarm. Specification 254,046, is referred to.

Title: Improvements in synthetic rubber-resin compositions
IPC: C08L9/00
Filed: 1947-06-27
Abstract: A thermoplastic composition comprises a homogeneous blend of a rubbery copolymer of butadiene-1,3 and styrene and a hard, inelastic copolymer of 50-85 per cent by weight of styrene and 50-15 per cent of acrylonitrile, the hard copolymer constituting 25-90 per cent of the mixture.  The mixing may be effected at elevated temperatures in, for example, a rubber mill or Banbury mixer.  Compositions containing less than 50 per cent of the hard resin result in tough, leathery materials which may be embossed and used for upholstery, bags, shoes, &c.  Those containing above 50 per cent result on calendering in stiff boardy sheets suitable for moulding and remoulding into hard products such as automobile fenders, helmets, golf club heads, golf ball covers and electrical appliances.  The softening point of the blend may be raised by vulcanization, e.g. of a mix including zinc oxide, sulphur, stearic acid and benzothiazyl disulphide, or by the addition of polydichlorostyrene.  A small proportion of the rubbery component may be replaced by other synthetic rubbers such as neoprene or butyl rubber, and the compositions may also contain pigments. U.S.A. Specifications 1,973,000 and 2,140,048 are referred to.ALSO:A thermoplastic composition comprises a homogeneous blend of a rubbery copolymer of butadiene -1, 3 and styrene and a hard inelastic copolymer of 50-85 per cent by weight of styrene and 50 - 15 per cent of acrylonitrile, the hard copolymer constituting 25-90 per cent of the mixture.

IPC: C03B7/086
Filed: 1930-06-02
Abstract: 352,195. Glass manufacture. BRITISH HARTFORD - FAIRMONT SYNDICATE, Ltd., 142, Ely Place, London.-(Assignees of Peiler, K. E. ; 16, Fernwood Road, and Barker, W. T.; 26, Ellsworth Road, both in West Hartford, Connecticut, U.S.A.) June 2, 1930, No. 17003. Convention date, June 3, 1929. [Class 56.] Delivering molten metal.-Relates to a feeder of the kind described in Specification 227,078, [Class 56, Glass], and consists in connecting the plunger to its operating cam through a toggle joint instead of by means of a rigid link, and in providing mechanism for automatically adjusting the effective length of the toggle at any selected time in the cycle of operation, so that glass charges of different weights and sizes may be delivered in cyclic order to the moulds of a forming-machine. The feeder comprises a plunger 3, Fig. 2, which is reciprocated above, and in line with, an outlet in the floor of a forehearth, and is carried by a bracket 4 supported by guide rods 7, 8. The bracket is reciprocated by a cam 10 which makes contact with a roll 13 on a pivoted arm 14 connected by a link 16 with a compound lever 20, as described in Specification 227,078. The lever 20 is connected with the bracket by a pair of toggle links 30, 31, and not by a rigid link as described in the earlier Specification. The joint 34 between the links is connected by another link 35 with a block lever 36 which is pivoted at 37 to the framework. Thus the movement of the lever 20 will be transmitted to the plunger 3 by the toggle member, and any movement of the lever 36 will cause an alteration in the effective length of the toggle member and an alteration in the character of the movement of the plunger. The block lever 36 is provided with a number of sockets 39 which form slideways for vertically adjustable contacts 40. Each member 40 is in contact with the lower end, the piston rod 45 of a pneumatic cylinder 47 which is secured to the frame, and a spring 50 maintains the member 47 in contact with the rod 45. Each of the cylinders 47 is connected by a pipe 52 with a valve 55, 56, or 57, Fig. 3, and each of these valves is operated by a cam 58 secured to the table 59 of the forming machine and close to a mould 60. In operation, the table 57 rotates in synchronism with the rotation of the cam 10 that reciprocates the plunger, and the toggle mechanism is adjusted so that the feeder delivers a mould charge of a given weight which is .suitable for an article made in one of the moulds 60. The cams 58 for the remaining moulds are so adjusted that they operate the respective cylinder 47, thus moving the link 35 and altering the effective length of the toggles. This alteration causes the delivery of a glass charge of different weight and size, and a glass charge of different weight or size can be delivered to each of the moulds by suitable adjustment of the cams 58.
