Filed: 1963-12-03
Abstract: 989,933. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 3, 1963. No. 47657/63. Heading H4K. A PABX extension engaged in a public exchange call may make a local enquiry call while holding the exchange call but not in communication, and may by further action bring in the exchange call to form a triangular conversation. Assuming that an extension is already connected to the public exchange, momentary actuation of an earthing pushbutton operates differential relay DR which connects up relay ER. A finder LF is started and in due course connects with the calling extension, whereupon relay EB energizes, looping the exchange line but disconnecting the extension therefrom. The extension receives dialling tone, and the enquiry call is set up by dialling, the impulses being repeated by relays LS, A. Relay AS energizes upon reply and prevents further impulses reaching the local switch train. In this condition, however, the dialling of the digit 1 results in the operation of relay CB which holds in series with CA and connects up relay CE in the line circuit, thus remaking the connection to the public exchange line. If the digit 1 is dialled again, relays CB, CE are released and the previous condition is restored. The calling extension may drop the enquiry call and revert to the original exchange call by again actuating the earthing push-button to operate DR. Relay RL pulls up to release the local switch train and the relapse of EB restores the connection to the exchange line.

Abstract: 1,220,970. Injection moulding. R. J. COLLION. 16 Oct., 1968 [17 Oct., 1967], No. 49103/68. Heading B5A. An injection mould clamping mechanism includes a first hydraulic ram 2 fixed to a support 1, a second hydraulic ram 6 between the first ram and the mould 5, the movable part 5b of which is secured to the piston-rod 7 of the second ram, and a pressure block 15 removably located between the adjacent ends of the pistonrods 10 and 7 of the two rams. The fixed part 5a of the mould is supported by tie rods 4. In operation the part 5b is moved by the ram 6 to close the mould, and the block 15 is then moved to a position between the ends of the pistonrods, after which mould clamping is effected by moving the piston 12 of the ram 2 a predetermined distance to act on the mould via the parts 10, 15, 7 and 5b. The displacement of piston 12 is produced by forcing a predetermined volume of fluid into its cylinder 8 from a metering chamber 24 of a ram 16 by a piston 19. Due to the differential surface areas of the piston 19 and the end 28 of its rod, the fluid pressure applied to the ram 2 is greater than the pressure input to the ram 16.
