Title: Improvements in or relating to compositions comprising polyethylene
IPC: C08L23/06
Filed: 1950-04-03
Abstract: An adhesive for bonding polyethylene sheet to the same or other substances comprises a mixture of polyethylene and butyl rubber which dissolves in an organic solvent to give a composition stable at room temperatures.  The mixture is prepared by working, e.g. by milling, at a temperature of around the softening-point of polyethylene, e.g. 225 DEG  F., cooling, and continued working at a temperature below the softening-point of polyethylene, e.g. below 160 DEG  F.  After the first milling, the mixture is preferably sheeted out and allowed to stand overnight when an insoluble boardy material results.  After remilling, the material is soluble in solvents such as toluol, xylol and naphtha.  The ratio of polyethylene to butyl rubber is preferably between 1/4 : 1 and 4 : 1.  The preferred polyethylenes have molecular weights of 10,000-20,000.  Additional components which may be included in the composition are low molecular weight polyisobutylene, oil-soluble terpene resins, oil-soluble non-heat-reactive phenolic resins, oil-soluble maleic glyceride resins, and anti-oxidants such as hydroquinone monobenzyl ether and mono- and di-heptyl diphenyl amines.  The solids content of the solutions should be from 20-80 per cent.  The compositions may also be used as coating compositions and as adhesives for other substances, and the bonding of polyethylene sheet to the inside of a tank wagon and the flocking of cloth are described.

Title: Improvements in or relating to systems of electrical signalling over common lines
IPC: H04Q5/06
Filed: 1952-07-09
Abstract: 723,969. Direct-call party-line systems. ERICSSON TELEPHONES, Ltd., and STEVENS, J. R. H. July 9, 1952 [April 10, 1951], No. 8265/51. Class 40 (4). [Also in Group XXXVIII] In a party-line system, at least one of the stations is provided with means for modifying the wave form of current drawn from an A.C. source to form a number of different types of current, e.g. A.C. alternate half-cycle pulses, D.C., D.C. + ripple, for calling selective stations along the line. A selector switch and halfwave and full-wave rectifier networks for a system using A.C. half-wave pulses and D.C. which may be applied to the line in either direction are described with reference to Figs. 1-3 (not shown) respectively. The basic receiving circuit for A.C. and half-cycle pulses (Fig. 4) comprises a full-wave rectifier network feeding a relay RC, the actuation of which is maintained during the reception of half-wave pulses by a condenser C2 and a shunt resistor R3. A rectifier MRG in the line selects the currents as regards direction of flow. In order to prevent false calling of A.C.-called stations by half-wave pulses or vice versa two of these basic circuits are connected in parallel across the line as in Fig. 5 and the contacts of the relays RA, RB are included in the local bell circuits. The bell is made to ring only in response to the receipt of both half-cycles at an A.C. called substation, Fig. 7, wherein both contacts RA and RB must be actuated to ring the bell BL, or, in the case of a half-wave called substation, Fig. 6, one of the relays serves as a guard to prevent the closing of the bell circuit by full A.C. The resistors R3 are replaced by inductants IA, IB in the practical circuit. Fig. 5, to provide a lower reactance in the shunt paths to the discharge of condensers C3, C4 and in a modification, Fig. 8 (not shown), the inductors are combined. Similar circuits for the reception of D.C. signals in which A.C. signals balance in the two networks and D.C. is effective only in one, are described with reference to Figs. 9 and 10 (not shown). A system including a master station called by magneto generator and able to call any subscriber by the above means, in which the master station can be asked by a subscriber to call a wanted subscriber, is mentioned and also a system wherein groups of subscribers may have a second call receiving circuit for setting up conference calls. The system is stated to be applicable also to selective signalling systems wherein it is desired to apply a variety of controls to remote machines.

Abstract: 456,108. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Branson, D. E., Holden, W. H. T., and Eyster, J. A.) March 20, 1936, No. 8385. Convention date, April 4, 1935. [Class 40 (iii)] Pairs of gas-filled valves RA, RB and SA, SB are used respectively for receiving and for sending signal impulses characterized by their polarities. When an incoming marking impulse applies a positive grid-potential to valve RB it energizes the rounder 6 and also causes the valve RA to be extinguished by the discharge of the condenser C1. A spacing impulse applies a positive charge to valve RA and thus causes valve RB to be extinguished and sounder 6 to be released. The impedances R3, R4, 5, 6 are so balanced that the sending transformer 8 is unaffected by the received signals. For sending, the valve RB remains in the energized condition and the operation of key 8 sends impulses through it, through sounder 6 and through transformer 7 to energize one and extinguish the other of valves SA, SB so as to put marking and spacing potentials on the outgoing line 41. Break signal. When the normally closed key 8 is opened during reception of signals a spacing impulse is sent to the distant station, and valve RB at that station is extinguished so that the local sounder fails to respond to the transmitter, thus giving a break signal to the operator. Duplex signalling. A two-way line L5, Fig. 2, feeds a one-way line L6 and is fed by a oneway line L7, the connections being effected through a bridge B. Each line L6, L7 includes a pair of gas-filled valves whose plates are coupled through a condenser C3 or C4 so that one valve is extinguished by the impulse that energizes its companion.
