Title: Improvements in or relating to Telecommunications Exchange Systems
Inventor: NOTTNAGEL W
IPC: H04Q3/62
Filed: 1967-11-23
Abstract: 1,162,720. Automatic exchange systems. SIEMENS A.G. 23 Nov., 1967 [24 Nov., 1966], No. 53353/67. Heading H4K. In a PBX having abbreviated dialling facilities, the output from the automatic dialling device is automatically inhibited if a busy condition e.g. network congestion is encountered at any stage during the setting up of a connection. A calling subscriber TN on gaining access to the dialling device RNG transmits a short code which is stored in KSP. The output from the latter is then translated, at UW, into a full directory number, the digits of which are inserted serially into the cells of store SP. If the call is to a PBX having direct inward dialling facilities contacts dw are operated after the PBX number is inserted in SP and the caller then dials the extension number required into store DSP. No further action occurs until dialling tone is reverted from the main exchange, whereupon relay T in a monitoring circuit TE, comes up. (ln is closed, by means not shown, when cell n in store SP contains a digit of the required directory number, the case where a directory number contains less than n digits is mentioned). Relay ST in the dialler follows and holds. Impulsing relay J is coupled to the first cell in store SP in order to repeat the contents thereof in pulse form to the main exchange. During each impulse train relay V comes up to disconnect T from the trunk. In the intertrain pauses, however, T is reconnected to the trunk and can come up if a busy tone is present thereon. Provided therefore, that the contents of cell 1 in store SP have been read-out, i.e. contact 1 back, relay B follows any further energization of T in order to disconnect the dialler from the trunk. If the initial application of dialling tone is delayed, a timer ZG times-out to effect forced release of the dialler by bringing up B over its II winding. If, instead of dialling tone, busy tone is initially reverted, the dialler does not distinguish between these until after the first impulse train is sent, when relay T comes up for the second time and disconnects the dialler.

A crystalline copolymer comprises units derived from a branched chain mono-olefin containing 4-6 carbon atoms and at least some but less than 5% by weight of units derived from at least one branched chain alpha octene. Crystalline copolymers are prepared by polymerizing the mono-olefin and at least one branched chain alpha octene in the presence of a catalyst obtained from (a) a solid crystalline compound of a metal of Groups 4 to 8 of the Mendeleef Periodic Table, the metal being in a lower valency state than its maximum and (b) an organometallic compound of a Group 1-3 metal. Preferably the feedstock contains 50 to 90% by volume of the C 4-6  olefin and 10 to 50% of the octenes. The C 4-6  olefin is preferably 4- methylpentene-1, and the octene is preferably that fraction obtained as a distillation cut between 110 C. and 111À5 C. from the base products of a butene-ethylene codimerization process. Catalyst component (a) is preferably a transition metal halide such as titanium trichloride, 2 (b) is preferably an organoaluminium compound such as aluminium diethyl chloride, and the molar ratio of (a) to (b) is preferably in the range 1: 1 to 1: 10. An inert diluent which is a non-solvent for catalyst component (a) may be used and suitable diluents are heptane, octane, benzene, toluene or xylene. The polymerization may be effected in the absence of a diluent, whilst maintaining the monomers in a liquid state. The concentration of catalyst component (a) is preferably 0À1 to 5À0 millimoles per litre of reaction medium. The preferred reaction conditions are a temperature in the range of -20 to 120 C., a sub-atmospheric, atmospheric or super-atmospheric pressure, and optionally the presence of an additional molecular weight control agent e.g. hydrogen. In the example, a co-polymer of 4-methyl pentane-1 and the preferred octene is produced using titanium trichloride and aluminium diethyl chloride, in n-heptane, the catalyst being de-activated with a methanol/acetyl acetone solution, and the resultant polymer precipitated in methanol. The polymer is washed with methanol and acetone, and dried.

Abstract: 1,224,143. Valves. JOSEPH LUCAS (INDUSTRIES) Ltd. 19 Feb., . 1968 [8 Dec., 1966 (2)], Nos. 54999/66 and 55000/66. Heading F2V. Flow through conduits 29 and 30 is controlled by one end of a member 10 whose movement in a cylinder 11 is controlled by a pilot valve 21 actuated by a solenoid. Member 10 has a piston 10a movable inside a sleeve 12, having a port 16, which can slide inside the cylinder and is centred by springs 13, 14. When valve 21 is opened, fluid flows through conduits 19 and 20 to each end of the cylinder 11. At the righthand side of the piston 10a the fluid passes to drain through the port 16. Fluid pressure on the left side forces the piston and sleeve 12 to the right until the piston blocks the port 16, whereupon the pressures on opposite sides of the piston equalize and the sleeve reverts to its formed position under the action of the springs 13, 14, the valve 21 having been closed. The member 10 is kept in this position by pressure acting on an extension located in a cylinder 23 until the valve 21 is opened again. In Fig. 2, not shown, the end of the member 16 actuates a closure member (33) to control flow through conduits (31) and (32). In Fig. 3, not shown, the movement of the member 10 is controlled by two pilot valves (36) and (37), either of which can initiate movement of the piston.
