Title: Improvements in or relating to telephone exchanges
Inventor: BUTCHER JOHN ANTHONY WEEKS
IPC: H04Q3/00
Filed: 1965-11-10
Abstract: 1,063,939. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 10, 1965, No. 47657/65. Heading H4K. In an exchange employing a co-ordinate switching matrix SM, for example of reed relays, a calling line is connected over the matrix to an idle link circuit CC and thence to a register REG, and the required call is subsequently established by the connection of the same link circuit over the matrix to the wanted line, the register being released. The registers R1 . . . . R3 and subscribers' lines are scanned under the control of a distributer DT, and a generator SG supplies in code form the identity of the lines. In each line circuit a gate G2 picks off the code from highways OH, and this is transmitted in the case of a calling line over gate G3 and highway H1 to a common control circuit CCM, or in the case of a busy line over gate G4 and highway H2. Other common highways mark the line circuits according to their condition. When a calling condition is found, a gate G1 is inhibited to stop the scan, and over highway H3 and gate G5 the line circuit is marked busy. An idle register and link circuit are allotted, and a mark is applied to highways H4, H5, the latter serving to provide a correct termination in the case of 4-wire switching. In consequence, markings are applied to leads RML, MHL to establish a connection between the line circuit LC and the register REG via the link CC. Scanning now restarts. The dialled number is received in a VF receiver VFR, and is compared with the numbers emitted by the generator SG over highways OH. When agreement is reached, the register sends a signal over H6 to the control circuit CCM to stop the scan in the position of the wanted party. In addition, a signal over H7 operates a gate G9 in the link CC, and a signal over H8 from the control circuit CCM marks the identity of the called line circuit, in order to connect the link CC thereto over the switching matrix. Ringing takes place, the register is released and scanning is resumed. If the marking on the called line circuit indicates a busy condition, no connection is set up and busy tone is returned.

Abstract: 1479416 Seaming non-metallic sheet material SIG SCHWEIZERISCHE INDUSTRIE-GES 11 Dec 1975 [27 Jan 1975] 50779/75 Heading B5K Apparatus for transversely welding and severing superimposed layers 25 of thermoplastic sheet material, e.g. superimposed webs or a flattened tube of plastics film, comprises two counter-rotatable welding jaws 3, 4 which simultaneously act upon the layers 25 from each during each revolution, the jaw 3 having a wedge-shaped head 7 with a tip 10 providing a cutting edge and the jaw 4 having a stripshaped anvil surface 21 co-operable with the cutting edge, the surface 21 being flanked by two resilient heat-resistant elongate members 20 1 , 20 2 , the jaw 4 being displaceable towards its axis of roation against resilient biasing means 14 and the distance between the axes of the jaws being less than the total of the maximum radial distances of the cutting edge and the surface 21 from the respective axes of rotation, whereby the jaw 4 yields when the jaws 3, 4 strike against one another. As shown, the steel jaw 3 has a foot 5 let into a groove 6 in a rotatable shaft 1, has an electrical heating element 8 embedded therein and is provided with cover plates 9 to prevent the layers 25 becoming overheated and to act as hold-down devices for the layers 25. The jaw 4, preferably unheated, is carried by bolts 12 displaceable in diametrical bores 13 in a rotatable shaft 2 and is urged away from the shaft 2 by compression springs 14 so that heads 17 on the bolts 12 normally engage shoulders 18, Fig. 3a. Heat-resistant artificial rubber elongate members 20 1 , 20 2  project from grooves 19 one on each side of the anvil strip 21. As the shafts 1, 2 rotate, the surface 21 and the tip 10 describe cylindrical surfaces 22, 23, respectively, the radii of which may be equal. Alternatively, the radius of the surface 22 may be 0À96-0À99 that of the surface 23. In operation, the layers 25 are fed, e.g. by rollers, at a speed corresponding to the peripheral velocity of the tip 10 and, as the jaws 3, 4 approach each other from the Fig. 3a position, the layers 25 are clamped between the member 20, and a flank 28, of the head 7 to form a first welded seam (29), Fig. 4 (not shown). As the jaws 3, 4 strike against each other, the jaw 4 is moved against the action of the springs 14 so that in the Fig. 2 position a clean cut (30) is made through the layers 25. Then, the flank 28 2  of the head 7 and the member 20 2  clamp the layers to form to second weld (31). In modifications (not shown), instead of the jaw 4, the jaw 3 is radially displaceable against spring pressure or both jaws 3, 4 are radially displaceable. Instead of springs, pistons acted on by compressed air may be provided.
