Title: Improvements in or relating to time division multiplex telecommunications exchange systems
IPC: H04Q11/04
Filed: 1965-09-14
Abstract: 1,085,933. Automatic exchange systems. SIEMENS A.G. Sept. 14, 1965 [Sept. 15, 1964], No. 39159/65. Heading H4K. In a time division multiplex exchange a subscriber breaks into an existing connection taking place in a first time slot of a highway by being allocated a second time slot during which the called, engaged subscriber of the connection is again connected to the highway, and by having capacitive speech energy stores associated with each subscriber all three subscribers may exchange speech energies with one another. In the system shown in Fig. 1, subscribers N1 to N4 are allocated speech energy stores L1C1 to L4C4 which are connectible to the highway SM by switches S1 to S4 controlled by two sets of circulating memories Ua, Uda and Ub, Udb and associated decoders Da and Db. In setting up a connection a calling subscriber's address N1, say, is recorded in the memories Ua, Uda in the first time slot allocated to the calling subscriber. The address of the wanted subscriber N2, say, is after being dialled into the exchange receiving circuit (not shown) stored in memory Ub at the first time slot position. After the control ST has checked by means of the comparator VB that N2 has not previously been stored in any other time slot position in either memory Ua or Ub, the control ST pulser memory Udb so that switch S2 opens in the first time slot to interconnect the two subscriber energy stores. A subscriber N3, say, wishing to break-in and call N2, has his address stored in the second time slot position in memories Ua and Uda and supplies the address of N3 to memory Ub as before but in the second time slot. A check is now made by the control ST to see if N2 is engaged. The address store AZ presents at its output each subscriber's address for one whole time frame of time slots and by comparators VA and VB the control ST is informed where N2 and N3 appear in the memories and deduces N2 is engaged and instructs memory Ubi to supply engaged tone in the second time slot. Subscriber N3 now dials the break-in signal which is stored in the auxiliary store Uauf in the second time slot position and in the circulating address store Um. When N 3  again appears at the address outlet of AZ and UM the control ST supplies to the memory Udb pulses which will connect subscribers N 2  and N 3  to the highway in the second time slot position. Speech energy from C3L3 now passes to C2L2 in the second time slot and in the following first time slot repasses to C1L1 so all three subscribers exchange speech energy. Additional subscribers may break-in forming a conference connection.

Abstract: 821,772. Waveguide windows. GENERAL ELECTRIC CO. Ltd. Dec. 20, 1957 [Dec. 28, 1956], No. 39559/56. Class 40 (8). [Also in Group XXXVI] A method of making a window seal comprises arranging a refractory metal cup 2, having in its base a central aperture 5 with tapered edges, between inner and outer vitreous quartz cups 1 and 3, one of which has a tubular stem 4 extending from its skirt, heating the rims of the quartz cups to seal them together (an inert gas such as nitrogen being passed into the assembly through the stem 4 to prevent oxidation) and subsequently evacuating the assembly and heating by oxy-hydrogen blowlamps to cause the quartz to collapse on to the metal, first across the aperture and then around the rest of the cup. The ends of the quartz skirts are then cut away to leave the metal skirts projecting (Fig. 3) so that they may be sealed into a device such as a waveguide, a metal ring being interposed if required. To prevent the skirts of the quartz cups adhering to the end of the metal cup skirt molybdenum foils 6 may be interposed. The refractory metal for the cup is molybdenum, but tantalum or indium are given as possible alternatives. Before assembly the cup is etched in an aqueous solution of sulphuric and nitric acids to reduce its wall thickness and produce a feather edge around the sealing aperture in the base. Suitable heating and annealing treatments are described. Specification 821,771 is referred to.

Abstract: 1,166,254. Shearing. FAIREY ENG. Ltd. 16 Dec., 1966 [17 Sept., 1965], No. 39853/65. Heading B3W. [Also in Divisions B8 and G6] Servicing tool for nuclear reactor fuel channels comprises a body adapted to be attached at its upper end to a hoist suspension and incorporating a power-driven shear operable to cut a broken tie-rod inserted into an opening in the lower part of the body and to retain the cut-off portion and also incorporating a television camera directed at the opening and means for actuating the shear by remote control under the supervision of the television camera. The tool comprises a base-plate 14 on which are mounted a pair of brackets 20 which support the links of a lever-operated toggle mechanism for actuating the shearing cutters 24, 25, which slide on guide rods 21. The toggle links 27, 32 are connected by a link 33 to a lever 36, which in turn is connected by a link 39 to a lever 41, which is pivotally mounted at 42 and is actuated by a pneumatic or hydraulic cylinder 46, Fig. 1 (not shown), or by a solenoid. The television camera 16 has a built-in focus control and lighting system and is situated parallel to the centre-line of the shear, in line with an opening through the base-plate. In order to facilitate the removal of fuel elements from a channel after the tie rod has broken, the tool is lowered into the channel and the shear cuts off any part of the tie-rod projecting above the uppermost fuel element. A grappling tool for engaging the fuel elements is then fitted on the tool so that it may be used to withdraw the fuel elements. The grappling tool comprises an annular support 63 in which is an annular slot 76. Pairs of pegs 78 extend across the slot and on each pair rest the heads of two T-shaped hooks 61, which have barbed ends 75. There are two sets each of three pairs of hooks, the hooks of each set being spaced 120 degrees apart and the two sets being separated by an angle of 40 degrees. The hooks are free to rock about either of the pegs and are biased towards a vertical position by a spring 80 which is secured to the underside of the base-plate by a screw 81. When the grapple is lowered on to a fuel unit at least three hooks engage the " strong-back " of the element so that it can be lifted from the channel. The grappling tool is fastened to the base-plate by two fixed latches 66 and a pivotable latch 59 which is actuated by a solenoid through a toggle mechanism 70. The toggle is broken to swing the latch out of engagement with a flange 64 on the support 63. The tool is lowered into the fuel channel after any projecting part of the tie-rod has been cut off and engages the fuel element which is withdrawn and conveyed to a debris container. The latch 59 is then disengaged to jettison the grapple and fuel element into the container.
