Title: Improvements in or relating to telephone systems
IPC: H04Q3/42
Filed: 1925-12-29
Abstract: 268,058. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. Dec. 29, 1925. Automatic exchange systems. - The release of a partly-established connection and the transmission of a busy signal to the calling party in the event of a busy condition being encountered is effected at a repeater in the calling party's exchange by a relay BR which is energized as the result of the response of a bridged relay I to the backward transmission of a busy signal from switches ahead, the relay BR on energizing opening the circuit of the normal release relay B. The operation of relay BR can only take place after the relapse of a slow-release relay BS so that busy-release of succeeding switches is dependent upon the relapse of two slow-release relays BS, B, and will not be brought about by accidental operation of the calling party's switch hook or calling device. The repeater shown is similar to that described in Specification 253,619, and has associated with it a hunting switch which selects an idle coder for use in working with call-indicator manual exchanges and a group selector which seizes an idle automatic to manual junction. When the coded number has been completely sent out, relay CZ is operated by earth sent back from the coder and the lower winding of relay H is bridged across the outgoing talking conductors. When the distant operator completes the connection, relay H operates and completes the talking circuit. If the calling subscriber releases between the operation of relay CZ and the completion of the call by the operator, the outgoing release trunk RT is marked busy over contacts 17 until the operator deals with the call. If the called line is busy, the operator's busy key connects battery to the upper speaking conductor and earth and battery alternately to the lower speaking conductor. At the first earth counection relay H operates and completes a circuit for bridged relays I, D. Relay H also opens the original circuit for relay BS which, however, remains locked over contact 23 of relay I. When battery is connected to the lower conductor relay I releases and remains deenergized for a sufficient time to permit the relapse of relay BS. The next operation of relay I, therefore, completes a circuit for relay BR which locks to contact 10 of relay A, connects up busy-tone and flash and busy-hold conductors BTF, BH, earths the incoming release trunk to hold the calling side of the connection and opens the circuit of relay B to release the called side. If the selector associated with the repeater finds all outgoing trunks busy, relay CZ operates over conductor OFB and relays H, I, BR operate as before. Busy-release arrangements similar to those shown may also be applied to a first code selector in systems employing register-controllers of the code-translating type. Specifications 229,371 and 267,608 are referred to.

Title: Improvements in or relating to the manufacture of rubber and the like materials and compounds thereof
IPC: C08J3/20
Filed: 1931-11-27
Abstract: Rubber is incorporated with accelerators and antiagers by adding the ingredients of the latter as liquids or solids to the rubber and condensing them in situ.  The rubber may be in aqueous dispersion, in solution or softened as by mastication and the ingredients may be emulsified or in solution.  When latex is used the conditions are preferably chosen so that the whole mixture sets to a general coagulum without separation of aqueous and rubbery portions.  The mixture may be heated to assist interaction of the ingredients.  One ingredient may be added to one portion of rubber and the other ingredient to another portion and the two mixed, particularly when masticated rubber is being used.  Such accelerators and antiagers include the reaction products of aldehydes as butaldehyde, crotonaldehyde, heptaldehyde, with aniline or other amines. Specification 358,089 is referred to. The Provisional Specification refers also to accelerators formed by the combination of an organic base such as diphenylguanidine with acetic acid, or mercaptobenzthiazole or a naphthol or by the combination of carbon disulphide with an organic amine such as piperidine or dimethylamine or aniline.
