Title: Improvements in or relating to pcm time-division multiplex exchange systems
IPC: H04Q11/04
Filed: 1970-03-03
Abstract: 1,263,007. Automatic exchange systems. SIEMENS A.G. 3 March, 1970 [4 March, 1969], No. 10003/70. Heading H4K. In a PCM, TDM exchange utilizing one time slot for transmitting signalling data in respect of connections taking place in the other time slots, each data signal is accompanied by a designation signal for identifying the time slot to which the data signal relates. A number of time slots may be grouped under a common designation signal, the data signals being related to the time slots by virtue of their order within the group. As shown, an address generator AG<SP>1</SP> supplies the address of a group of subscriber lines VS<SP>1</SP> during a frame period. The conditions of the a, o wires of each line in the group are sampled and the results stored in parallel in shift register SR<SP>1</SP>. The conditions may be in respect of dialling signals or clearing signals as described. The address of the group is also entered into the shift register. Thereafter during the time slot, e.g. p16, devoted to data signalling the contents of the register are serially shifted from the register on to the highway PCM. An obvious system for decoding and distributing the data signals at the receiving end of the highway is depicted in Fig. 2 (not shown). The continuous transmission of the time data during successive time slots of the data channel may be effectively interrupted, if one of the lines changes its state, by transmitting the change data together with the identity of the line (or rather, the identity of the time slot utilized by the line) producing the change during the next time slot in place of the line data originally intended for this slot. The original D.C. line signals may be reconstructed (e.g. with relays) at the TDM exchange so as to be compatible for subsequent signalling to an electromechanical exchange.

Title: Improvements in and relating to dynamo-electric machines and other electrical apparatus having slots containing conductors
IPC: H02K3/12
Filed: 1926-04-16
Abstract: 274,199. Parsons, Sir C. A., Rosen, J., and Horsley, W. D. April 16, 1926. Transformers.-In slot-wound transformers, or other electrical apparatus having conductors of different voltages arranged side by side in slots, extra insulation is provided for the higher voltage conductors and to accommodate this, the relation between the cross-sectional dimensions of the slot and the conductors is graded at different places in the slot. Metal sheaths may be placed around some of the conductors to equalize the potential drop across the insulation. Fig. 3 shows a slot containing three conductors B, C, D at the bottom, middle and top of the slot and respectively at high, intermediate and low voltage. The section of the conductor B is such as to allow a maximum thickness H of insulation around it. Similarly, the sections of the conductors C, D which are equal in area to that of B, are shallower than that of the conductor B and broader in such proportion as to leave room for insulation thicknesses J, K suitable to their respective voltages. In place of varying sections for the conductors and a constant slot width, a constant section may be employed. The invention may also be applied to tapering or other non-rectangular slots. For circular slots, the conductors B, C, D may be of the sections shown in Fig. 5. Fig. 4 shows the use of metal sheaths L, M, as described in Specification 237,960, for equalizing the potential gradient across the insulation, the sheath L, which is integral or in operative contact with the middle-voltage conductor C being arranged to enclose the insulation around the high-voltage conductor B and the sheath M being similarly disposed with respect to the insulation and the low-voltage conductor D. In place of being U-shaped with overlapping edges, as shown, the sheaths may be applied in the form of tape. The conductors with their graded insulation and sheaths may form a composite bar carried from slot to slot over the end of the core and two or more such bars may be laid in the slot to give a multiple-layer winding. The conductors may be subdivided into strands which are transposed for the reduction of losses or their cross-sectional areas may be so altered as to reduce the losses.

Title: Improvements in means for regulating internal combustion engines
IPC: F02M11/02
Filed: 1944-05-31
Abstract: 579,554. Regulating. CARTER CARBURETOR CORPORATION. May 31, 1944, No. 10455. Convention date, May 5, 1943. [Classes 7 (iii) and 7 (vi)] An internal-combustion engine having a plurality of cylinder groups A, B, is regulated by cutting out some of the cylinders by means comprising separate intake conduits 4, 3, to supply combustible mixture to each group, a manually operated throttle valve 13 for controlling the fuel supply to group A, the conduit supplying the other group being unthrottled, and a fuel valve 25, actuated by a combination of suction and throttle position, for controlling the fuel supply to the unthrottled group. When the throttle is opened to start the engine the fuel valve 25 and a metering rod 9 are raised through a connection comprising a slot 29, a cross pin 31, and a finger 32 carried by a lever 33, and a one-way connection 15 so that starting takes place on all the cylinders. As the engine speeds up the vacuum in the outer intake manifold 4 increases to about twelve or fifteen inches of mercury which, applied through an orifice 17, is sufficient to draw a piston 26 downwardly against a spring 27 and close the fuel valve 25. The engine then continues to operate on the outside group of cylinders only, until the vacuum falls to about four inches of mercury when the valve 25 is opened by the spring 27. To ensure that fuel discharge takes place instantly on opening valve 25 a cylinder 39, containing a floating piston 40, is mounted at the base of nozzle 24a, A spring 41 and suction, acting through a conduit 42, synchronizes the movement of piston 40 with the operation of the valve 25 which is maintained in the fully open or fully closed position by means of a spring 35, bent as at 36, 37, to ride over a "hump" 38. An accelerating pump 18 and thermostatically controlled choke valves 21, 44 are also provided. Specifications 412,957 and 472,090 are referred to.

Filed: 1945-04-26
Abstract: 625,088. Bending glass tubing. BRITISH THOMSON-HOUSTON CO., Ltd. April 26, 1945, No. 10532. Convention date, April 27, 1944. [Class 56] Relates to apparatus for bending into arcuate or circular shape lengths of glass tubing particularly for electric discharge devices such as fluorescent lamps. A length of tubing 18, Fig. 1, is supported horizontally by a roller 19 and its rear end R is engaged by a shoe 23 formed at the end of a tube 15 which is offset from the axis of the tube 18 and which is carried by a shoe 12 slidably mounted in a stationary guide 10. The shoe 12 is moved by chain and sprocket gear 30 to push the tubing 18 forward through initial and final electric heaters 29, 60 and over gas burners 59, and the leading end L of the tubing is engaged, and manually locked, in an asbestos-lined peripheral groove in a rotating drum 62. On continued movement of the shoe 12 and clockwise rotation of the drum 62 the softened tubing 18 becomes wrapped around the drum, being bedded in the peripheral groove 66 therein as shown in Fig. 9. To preserve the uniform bore of the tubing 18 an inert gas under slight pressure is passed therethrough from the tube 15 by way of a small tube 21, Fig. 9, extending through the rear of the tubing 18, the valve controlling the supply of this gas being automatically actuated at the appropriate time. The supply of combustible gas for the burners 59, of current for the final heater 60 and of current for the heater 29, additional to that constantly passing therethrough, is also automatically controlled during the cycle of operations and at the end of the cycle the motor driving the chains and drum is automatically switched out. The drum is made in two portions relatively separable about the centre line of the peripheral groove to permit the removal of the completely bent tubing therefrom. The lamp may be completed by adding a base of the type described in Specification 560,244, [Group XL].
