Patent GB-1040486-A (GB)
Title: Improvements in or relating to automatic telephone exchanges
Inventor: BROWELL LESLIE JAMES
IPC: H04Q3/00
Filed: 1963-05-31
Abstract: 1,040,486. Party-line systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 24, 1964 [May 31, 1962], No. 21876/63. Heading H4K. An exchange in which called subscribers' line circuits are marked for setting up calls is modified for party line working by the provision of a relay circuit connecting a subscriber's line circuit to a two-conductor party line and the marker so that the subscribers' line circuit is marked via first or second relays of the relay circuit according to the party to be called and operation of the relay completes a circuit over the speech wires in such a manner that ringing current on one speech lead of the subscriber's line circuit is connected to the appropriate party line conductor to ring the wanted party's bell. Incoming calls.-X party is called by a marking on terminal XM which energizes relay SX and sends a line marking over M to the subscriber's line circuit, which circuit returns earth on terminal S to hold SX for the duration of the call. SX connects conductors A, B of the party line to the + and - leads of the line circuit respectively so that ringing current applied to the - lead appears on conductor B where it is arranged to ring X party's bell. Y party is called by a marking on YM and relay SY switches over conductors A and B so that ringing current now appears on conductor A where it rings Y party's bell. Outgoing calls.-X party originates calls by operating a push-button key to apply earth to conductor B which is connected by strap XOB and contact SY3 to the - lead of the line circuit. The line circuit returns earth over terminal S to operate relay SX so that when the push-button key is released the usual calling loop is extended to the line circuit. Metering pulses received at SP are extended to X party's meter XSM. When Y party operates his push-button key, earth, applied to conductor A, operates relay LY to apply earth to the - lead of the line circuit which again returns earth to S. This earth holds LY and operates SY to remove earth from the - lead and complete the calling loop to the line circuit. Metering pulses are now fed to YSM. Either or both parties may be barred from making calls by the removal of corresponding straps XOB, YOB. Trunk offering.-The operator's marking of XM or YM ignores the busy condition of the line circuit and if the marked relay is already operated there is no change in any of the relays and the operator is connected to the line to request the subscribers to clear. If SX is operated when YM is marked or SY operated when XM marked, change-over of relays SX, SY occurs, but in no case is the condition of LY affected during trunk offering.

Title: Boron-containing synthetic resins
Inventor: PEARCE CHRISTOPHER ARTHUR
IPC: C08G79/14
Filed: 1958-07-10
Abstract: Resins are obtained by reacting a boron multi-halide or boron multi-ester with a difunctional Grignard reagent followed by hydrolysis of the reaction product.  The preferred reactants are boron trifluoride and p-phenylenedimagnesium dibromide but tri-n-butyl borate may be used in place of boron trifluoride.  An example is given of the preparation of a resin from p-phenylene-dimagnesium dibromide and either boron trifluoride, in the form of its ether complex, or tri-n-butyl borate.  The resin produced is thermoplastic when heated for short periods but when strongly heated for long periods or when heated at reduced pressure it is thermosetting and stable up to 350 DEG C.  It is a good electrical insulator, has a low dielectric constant and is useful as a laminating resin e.g. filled with glass fibre.
