Abstract: 1501474 Rotary positive-displacement fluidmachines UNISCREW Ltd 16 July 1975 29927/75 Heading F1F In a double-acting compressor, which may be of the sliding-vane type as shown in Fig. 1, a valve 12 when open allows gas in a discharge pipe 8a to pass into one of the working chambers 104a, 104b which is for the time being isolated from both suction ports 5b and a discharge port 7b, this arrangement being said to reduce the power consumption. While the valve 12 is open a check-valve 10 is closed owing to loss of pressure in the pipe 8a. Preferably, the valve 12 opens when the delivery flow-rate is at or near the maximum. A valve 16 may be provided to regulate the inflow of gas in accordance with the pressure in a delivery duct 9. To obtain greater economy, a spring- loaded valve may be disposed in the casing wall portion 4a and arranged to open with the valve 12, so as to reduce the compression ratio in the respective working chamber, Fig. 7 (not shown). The valve 16 may be dispensed with and circumferentially-movable plates, or "shells", 48a, 48b, Fig. 9, be provided to regulate the gas flow at the suction ports according to the discharge pressure. Arrangements generally similar to those shown in Fig. 1 may be comprised in a compressor of the worm and worm-wheel type, Figs. 17-19 (not shown); and, instead of the valve 16, axiallymovable elements (222), Figs. 20-22 (not shown), may be employed to regulate the gas inflow.

Title: Device for switching on a transformer for a short time interval
IPC: H02H9/00
Filed: 1951-12-27
Abstract: 698,595. Switching systems for transformers. BALTEAU, M. J. F. J. Dec. 27, 1951 [Dec. 28, 1950], No. 30195/51. Class 38 (iv). To ensure uniformity of the current impulses delivered by an X-ray, spot-welding, or other intermittently energized transformer 5, a contact 11 of a switch I vibrates between contacts 9, 10 in synchronism with the supply to the transformer when the latter is energized and comes to rest on one of these fixed contacts when the energization of the transformer is interrupted, thereby preparing a circuit which ensures that when the transformer is next to be energized it will be connected to the supply at such a point in the voltage cycle that current flows in the same direction as immediately prior to the previous interruption. In the arrangement shown, switching is effected by a relay B1 having contacts 6 controlling the supply circuit to the transformer and contacts 14 controlling the connection of the grids 19, 20 of thyratrons T2, T3 to a peaking transformer G energized from the same supply, the thyratrons alternately energizing (when contacts 14 are closed) windings B2, B3 and so causing the vibration of the contact 11. Closure of a time switch A prepares a circuit for the energization of relay B1 over a further thyratron T1, which subsequently conducts under the control of the peaking transformer, the polarity of the half cycle in which conduction occurs being determined by which of the contacts 9, 10 is engaged by the contact 11 which, in turn, is dependent on the polarity of the last half cycle of energization of the transformer. Relay B1 may be so adjusted that its contacts close threequarters of cycle after energization of its coil, so that the contacts close when the supply voltage is passing through zero. The switch A may also be such as to cause disconnection of the transformer at a zero voltage point of the cycle.

[Also in Division B8] The apparatus employs a needle 50 to introduce cable identifying sleeves on to a wire 54. Needle 50, Fig. 1. The needle has a head 52, a taper 51 which carries the sleeves and a socket 53 for attachment to the wire 54. Apparatus 100, Figs. 2 and 4. The apparatus is operated by a fluid cylinder which moves a rod 67 to the left and then to the right. The apparatus comprises a head 68 secured to rod 67, a carrier 64 which carries collets 73 and a plate 70 and a pivoted trigger 75; spring- biased strippers 77, and levers 81 pivoted to plate 70. Operation.-The sleeves are introduced on to needle 50 and wire 54 is secured to the needle at 53. The head of the needle is passed between the open rollers 83 of levers 84, through the strippers 77 and into collets 73. Then the rod 67 is moved to the left by the fluid cylinder. This causes head 68 to move leftwards and to unhook the trigger 75 from plate 70. Next, head 68 engages plate 70 to move the collets 73 leftwards to secure the head 52 of the needle and rollers 83 to close on wire 54. Further movement to the left then causes plate 70, head 68 and carrier 64 to move as a unit. This displaces needle 54 to the left through the strippers 77 and the strippers engage the sleeves thereon and retain them as the needle travels leftwards so that the sleeves pass on to the wire 54. When the rod 67 moves back to the right the collets 73 are eased and levers 84 opened so that the needle and wire may be withdrawn.
