Title: Improvements in high voltage current transformers
IPC: H01F38/30
Filed: 1966-03-18
Abstract: 1,099,573. Transformers. GENERAL ELECTRIC CO. March 18, 1966 [June 14, 1965], No. 12056/66. Heading H1T. The turns ratio of a high voltage (50-350 kv.) liquid immersed, current transformer is varied by re-arranging external links 37, 38 between the four terminals of the primary winding 31. The conductors of the primary 31 are arranged in looped pairs, symmetrically disposed on either side of a metallic conduit 17 traversing the upper housing 3, each conductor being passed from one terminal, e.g. 35 (Fig. 5) through the conduit, around part of the inner periphery of the housing 3 and through the conduit 17 again to the diametrically opposed terminal 35a. The conductor loops are supported on wooden blocks (50), (Fig. 3, not shown), between the housing and arcuate insulating barriers 32, 33. The housing 3 and conduit 17 are connected to a terminal 36 by a strap (44) (Fig. 7, not shown), to be at high line potential, and the housing assembly is clamped together in fluid-tight manner by four tie-rods 8 secured to brackets 13 on the metallic base plate 5 and to two transverse bars (11) in the upper housing 3 and above the liquid. The secondary takes the form of an "eye-bolt" and comprises an annular magnetic core 20, concentric with the conduit 17 and grounded through the metallic tube 22a of the secondary stem 22, and carrying a toroidal secondary winding 21 whose output leads are connected via terminals 25, 26 in the grounded terminal casing 7 to externally accessible terminals (29). Shielding is provided by a metallic cylinder 46 extending from the housing 3 into the high voltage insulating column 2, a metallic disc 47 bolted to the housing 3 below the liquid surface and at high line potential, and a split annular shield 60 around the secondary winding 21 and grounded through lead 61 and terminal 30. This shield 60 may also be used to obtain an indication of the primary voltage. The conduit 17 may be insulated by either wrapping or sheet 55, and the secondary assembly bound with vacuum impregnated tape. The conductors emerging from the conduit 17 are bound at 51 into two groups and the two groups taped together and to the conduit at 52 by alternate layers of plastic impregnated glass tape and permeable insulation such as crepe paper.

Title: Improvements relating to Anchors for Submarine Mines.
Inventor: STOCKUM ABRAHAM JOHANNES VAN
IPC: F42B22/16
Filed: 1918-07-26
Abstract: 125,297. Stockum, A. J. van. July 26, 1918. Mines, marine.-Relates to mines provided with mooring apparatus adapted to anchor the mines automatically at a given depth. According to the invention, the anchor contains a cable drum which is stopped by a pawl urged towards the drum by a spring and away from the drum by a hydrostatic diaphragm. In the form shown, the mooring cable 3 on its way out from the drum 1 passes round a pulley 4, which drives a screwthreaded spindle 23 through bevel gearing 21, 22, and the rotation of the spindle draws a non-rotatable nut 25 along, stretching a spring 20 connected to a lever 18, which is also connected to an hydrostat 14 and to another lever 42. An initial set is given to the spring by means of a detachable external handle 27 while the cable is loose on the pulley 4 before the mine is laid. When, during the mooring operation, the anchor goes to the bottom and the mine reaches the predetermined depth, the spring 20 overcomes the hydrostat and swings the levers 18, 42, bringing the toe 49 of the lever 42 in the path of a finger 16 pivoted to a disk 38 driven by a gear train from the drum, which is thereby stopped. The pivotal action of the finger 16 is limited by stops and controlled by a spring, the arrangement being such that as soon as the finger touches the toe 49, it swings further out so as to become more fully engaged by the toe. The disk 38 is connected to its spindle by a coiled spring, which, in conjunction with the spring of the finger 16, serves to prevent shock at the moment of stoppage. The gear train comprises a disk 31 provided with pivoted shoes 32 which are pressed by centrifugal force against the inner part of a fixed rim 30 in order to check the unwinding speed of the drum.

Title: Industrial lift trucks
Inventor: QUAYLE GEORGE FRANCIS
IPC: B66F9/10
Filed: 1960-04-07
Abstract: 879,310. Lift trucks. YALE & TOWNE MANUFACTURING CO. April 7, 1960, No. 12357/60. Class 78 (3). In a lift truck having a lifting carriage 10 movable by means of two pairs of parallel links 14, 15 and 21, 22, actuated simultaneously by hydraulic rams 20, 25 respectively, a valve unit 34, operated by a linkage 57, 61, 55, 54, 50, 52 cuts off the supply of fluid to either ram if it begins to lead the other thereby tending to cause the links 12, 13 to move out of a predetermined co-ordinated path of travel. The automatic control of the rams can be overridden if desired by moving a control arm 67 connected through links 70, 71, 64 to link 61 in the linkage system which controls the valve unit. In operation, if e.g. ram 25 begins to lead ram 20, link 57 rocks bell crank lever 61 in a counter-clockwise direction exerting a force on link 52, via links 55, 54, 50 to push to the right the valve member 42 and thus cut off communication between the inflow line 29 and the duct 41 leading to ram 25, but still allowing fluid to flow to ram 20 via bore 46 and duct 40. When the rams are co-ordinated again, the valve member 42 automatically returns to its normal position. By moving the control arm 67 the valve member 42 may be moved to the left or right to cause the rams 20, 25 and thus the links 14, 15 and 21, 22 to move in a path other than the co-ordinated path described above. Specification 837,344 is referred to.
