Title: Junctions, points, crossings, turnouts, and the like for overhead electric lines
IPC: B60M1/14
Filed: 1948-03-10
Abstract: 644,509. Frogs for overhead electric conductors. WISEMAN & CO., Ltd., A., ARTHUR, A. J., and SAVAGE, J. C. March 10, 1948, No. 7296. [Class 104 (iii)] A junction or switch for the overhead wires of a tramcar or trolley-bus system comprises a stationary frog a provided with two spaced abutments or upstanding walls 9, 10 which co-operate with a cam or eccentric 8 located between them and pivoted on a switch plate which, in turn, is pivoted to the frog, the cam being so arranged that when in either of two operative positions it is firm against retrogressive movement about its axis by reactive pressure from the switch plate. The switch plate 4, carrying a straight tongue 1 and a curved tongue 2, is mounted on the underside of the frog a on a pivot 3 about which it can be turned through an angle of about 10 degrees to bring either tongue into the operative position. A boss 5 on the switch plate 4 projects upwardly through an arcuate slot 6 in the frog and forms a mounting for the pivot 7 of the cam. Angular displacement of the cam is effected by a lever 12 with a pin-and-slot connection to an arm 15 pivoted to the frog at a point 15a located on a line between the cam 8 and the pivot 3 of the switch plate. The arm 15 is operated manually or by electric power through two diametrically opposite arms 20, and has two other arms 17, 18 at right-angles thereto, one of the latter arms being used for the attachment of a spring 16 which assists in holding the switch member in the most-used position. As shown, the abutments 9, 10 which co-operate with the two peaks 11a of the cam 8 are inclined towards one another at an angle of about 10 degrees, and the cam is so dimensioned that when either of its peaks 11a is in its final or operative position relative to its associated abutment wall 9 or 10 a part of the cam adjacent to the pivot 7 is in contact with the other abutment wall.

Title: Improvements in and relating to systems of electric motor control
IPC: B60L15/04
Filed: 1920-03-13
Abstract: 163,845. British Thomson - Houston Co., Ltd., (General Electric Co.). March 13, 1920. Controllers, actuating-mechanism for. - Pneumatic and like operating mechanism for motor controllers comprises two cylinders 24, 25 with pistons 22, 23 acting in opposite senses upon a rack 21 in gear with a pinion 19, the shaft of which carries a number of cams 17 bearing upon levers 18 attached to individual contactors 15. Starting from the position shown, successive short movements of the rack from left to right rotate the cam shaft by steps and close the contactors in succession. Each step is effected by admitting compressed air behind the piston 22, and the pause after the step is produced by admitting compressed air behind the opposing piston 23, the alternate communication of the cylinders to pressure and exhaust being controlled by electromagnetically operated valves 28, 29, connected in circuit with a master controller and subsidiary switches. In order to ensure a quick beginning of each step, and a gradual easing off at the end the exhaust valve 56 of the cylinder 25 is provided with a large and a small outlet. A wave-cam 61 on the pinion shaft acting through a tappet 59 opens the large outlet immediately after full pressure has been established behind the piston 22, thus cancelling the opposing pressure and allowing the rack to move. Before the completion of the step the tappet 59 returns, and thus throttles the exhaust down to the small outlet. The Specification describes the circuit connections and subsidiary switches for applying the invention to a series-parallel controller, the general arrangement being similar to that described in Specification 110,246.

In a clutch comprising a driving and a driven member separated by an electro-viscous or magneto-viscous fluid, there is provided a field which produces a spatially non-uniform distribution of apparent viscosity in the fluid, the field varying with time so that the relative velocity of the region or regions of greatest apparent viscosity and the driven member is reduced. As shown, a driving member 11 is provided with three electrodes 14, 15, 16, connected to a three-phase A.C. source 17, and a driven member 10 carries a common electrode. The phasing of the A.C. is such that the field rotates in the direction opposite to that of the driving member, and by sensing the speed difference between the members 10, 11, using a sensing device 18, the frequency of the source 17 may be controlled so that the field is stationary relative to the driven member 10. The electrodes may be replaced by wound polepieces. It is stated that the arrangements disclosed reduce the heat generation and power loss in clutches of this kind.

Abstract: 1,158,981. Tubular heat exchangers; steam reheaters. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 16 Feb., 1967 [22 Feb., 1966], No. 7679/66. Headings F4A and F4S. In a heat exchanger used, e.g. as a steam reheater having a tube bundle 26 composed of sets of tubes extending between inlet and outlet header structures 20, 25 respectively, each header structure is subdivided by a series of tube plates 22, 23, 24 into separate header compartments 17, 18, 19, successive tube plates being penetrated by a decreasing number of tube sets so that each set opens into a respective header compartment. The heating fluid, e.g. steam at super-critical pressure enters through inlets 11, 12 and 13 in the header compartments 17, 18 and 19 and leaves through similar compartments in the outlet header 25. The fluid to be heated, namely steam, after entering the U-shaped sheath 21 enclosing the tubes 26 at 28, flows countercurrently between the tubes to exit at 29. The tubes of the sets are interspersed within the tube bundle 26. The heat exchanger may alternatively be used as a double wall heat exchanger wherein only two sets of tubes are used to make up the tube bundle. Water is passed through one set of tubes to be heated by hot sodium or sodium/potassium alloy passed through the other set, thus producing steam; an intervening heat exchange liquid is provided in the sheath 21 to surround all the tubes.

An earthed grid circuit should be used with a slope to plate current ratio not less than 0.75 per volt, a slope greater than 3 m.a. per volt, and an amplification factor lying in the shaded area of the figure, in which it is plotted against frequency. A high impedance output circuit-50,000 ohms unloaded, or 10,000- 15,000 ohms loaded-is desirable ; this involves using a coaxial-line circuit with the anode forming part of it, and a grid of low inductance with a pitch less than 0.008 inches. A small variable condenser of 0.5 ÁÁF may be incorporated in the output circuit for fine frequency adjustment. The necessary low-loss input circuit involves coaxial lines, brazed or soldered grid wires, and a spacing between cathode and grid less than 0.006 inches. A low grid inductance of less than 1 mÁH also ensures small coupling between input and output circuits, being equivalent to a feedback capacity of 0.005 ÁÁF.
