Abstract: 1,207,365. Automatic exchange systems. CIT - COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS, and SOC. LANNIONNAISE D'ELECTRONIQUES. 14 Dec., 1967 [23 Dec., 1966], No. 56964/67. Heading H4K. A non-blocking t.d.m. switching network connects any one of the P channels of each of N incoming highways LRE to any one of the P channels of each of N outgoing highways LRS, the incoming highways LRE each having a buffer store MT, the outgoing highways LRS being grouped each group being served by an associated intermediate highway LJ and distributer CR, connections between the incoming highways LRE and the intermediate highways LJ being governed by address registers MC associated with each intermediate highway LJ. The highways are all seven wire highways on which the seven bits of PCM channels are sent in parallel. Each highway is multiplexed for 32 channels and the intermediate highways LJ are further multiplexed to provide N2 + 1 distributer time slots within each of the 32 channel time slots: N2 being the number of outgoing highways in each group. Buffer stores MT register the incoming PCM codes in compartments corresponding to the PCM channels. The codes are registered in the first of the N2 + 1 distributer time slots and are read out in the required outgoing PCM channel, on to that intermediate highway LJ giving access to the group in which the wanted outgoing highway appears, and in that distributer time slot during which the associated distributer CR gives access to the wanted outgoing highway. The selection of that point in time at which the buffer stores are read out is made by the appropriate one of the address registers MC which is set up in a manner not disclosed so as to address the storage compartment of the incoming PCM channel for read out in the directed outgoing PCM channel and in the correct distributer time slot in that channel. The address registers MC may be circulating delay line or looped stepping registers.

Abstract: 1321170 Biaxial stretching of films ERWIN KAMPF MASCHINENFABRIK 9 Dec 1971 [11 Dec 1970] 57276/71 Heading B5B [Also in Division D1] Apparatus for simultaneous biaxial stretching of a sheet of thermoplastic material comprises a preliminary treatment zone 1, a stretching zone 2 and a zone 3 for after-treatment of the sheet web, with grippers 6 arranged on a guide rail means 5 for continuous circulation and driven by variable lead transport screws 8 and 12 and constant lead transport screws 7, 9 and 11, connected together, with their axes inclined, by at least one helical spring 14, 15, 16, the extremis ties of which are arranged in extension of the guide faces of the transport screws, and the principal diameter of which corresponds to the diameter of the transport screws at the guide faces thereof. As shown, the bottom portion of Fig. 1 shows schematically a continuous circulation track 5 for the grippers 6, while the top portion represents the transporting facilities for the grippers 6 which are normally carried by a guide rail for return. Grippers 6 are close together in pre-treatment zone 1, become spaced apart in stretching zone 2 and are conveyed further apart still in the after-treatment zone 3. The return of the grippers is effected by transport screw 11 with constant lead and transport screw 12 with decreasing lead. Each extremity of the helical springs is received by and secured in an edge cut out at the ends of the grooves of adjacent transport screws. Where only one helical spring is used between adjacent transport screws, the relevant helical spring is connected to the guide face of the groove so that a force is continuously applied to the grippers 6 in the direction of transport. Alternatively, two helical springs 14 and 20 can be arranged cohelically so that their coils have a distance from each other equal to the width of the groove constituting the guide face, each extremity of the two helical springs being received by and secured in an edge cut out of the guide face of a transport screw. This is especially useful in the transition following the stretching zone 2 (springs 14, 20), since considerable tensile stress is initially present in the film to be heat-set in the after-treatment zone 3. The transport screws are carried by rollers 17 distributed over the circumference of the screws, the screws being connected by means of a coupling shaft 18 of the universal or cardan type, and driven by drive motors 19 which can also be used for driving the reversing wheels 10 and 13.

In the embodiment shown the worm 15 is driven by a shaft 10 through a coupling 12 and the axial thrust (in the direction of the solid arrow) acts through a thrust bearing 60, a member 21, a retainer 41 for springs 45, the springs 45, a retainer 30 for the springs 35 and the springs 35, which springs yield before springs 45. Nuts 27, 32 and 53 are provided to adjust the preload of the springs. In the reverse direction of rotation, and hence of thrust, the thrust acts through nut 27 and retainer 30 on the heavier set of springs 45 only. A pinion 65 is rotated by the axial movement through engagement with a toothed surface 25, and may operate electrical switches in response to the movement. Two further embodiments are also described (Figs. 2 and 3, not shown) in which the spring arrangement allows both sets of springs to operate in both directions of thrust.
