Title: Apparatus for controlling the sale of goods by auction
IPC: H04L12/18
Filed: 1926-09-04
Abstract: 278,154. Wouda, S., and Hoorn, L. J. J. van der. Sept. 4, 1926. Checking receipts.-In an electrical system for determining the highest bidder and the amount of the bid a pointer is caused to move over a series of increasing values so long as more than one bidder maintains his switch depressed and to be stopped when one bidder only remains in circuit. In the arrangement shown in Fig. 1 the pointer at W is stopped by a detent controlled by a magnet A. The double-pole bidders' switches D<1>, D<2> - - are connected up in series as shown and each controls also a relay switch DS<1>, DS<2> - - in the circuit of a second source LB. While more than one bidder's switch is depressed the circuit of the first source DB is incomplete and none of the relays is energized. When, however, one bidder only is holding his switch down, the circuit through the corresponding relay switch is made and a circuit from LB is completed through an indicating lamp L<1> - - an electromagnet AR and the magnet A. The pointer is thus stopped at the figure reached and the magnet AR breads the first circuit at V to render the bidders' switches ineffective. In other constructions the stopping of the pointer is effected by the diminution of current through the magnet A or a relay, owing to the retention in circuit of only one bidder's switch and its accompanying lamp or coil resistance. In the arrangement shown in Fig. 4 the bidders' switches D', D<2>, D<3> control relays in circuit with lamps L<1> L<2>, L<3> and the lamp battery LB. Depression of two or more switches enables the relay AR to hold off the contact V but when one switch only is down the contact is closed to complete a circuit for the magnet A with consequent stoppage of the pointer.

Title: Methods of producing canned fuel elements for nuclear reactors
Inventor: WINTER AAGE CHRISTIAN
IPC: G21C21/08
Filed: 1961-06-19
Abstract: 908,857. Nuclear fuel elements. ATOMENERGIKOMMISSIONEN. June 19, 1961 [June 28, 1960], No. 21991/61. Class 39 (4). A fuel element comprising fuel rods 3 stacked in a can 1 in which they are surrounded by a metallic heat exchange medium is made by loading the fuel rods 3 into the can 1 with the heat exchange medium interspersed between them, for example in the form of discs 4 and heating the cam 1 in order to melt the heat exchange medium. A compression device consisting of a connection disc 5 and a support 6 loaded by a spring 7 is connected to the upper end of the can 1, air being removed through a tube 8 leading to an air pump. To heat the can 1, it is pushed in the direction of the arrow 9 through a heating zone 10, e.g. a high-frequency coil, so that the discs 4 are melted successively. Owing to the pressure from the compression device and vibrations produced by a vibrator 11, the molten metal is forced out into the space between the can 1 and the fuel rods 3. The method is particularly suitable for use with ceramic fuel and suitable metallic heat exchange media are lead, tin, antimony and bismuth. If desired, a metal alloy, e.g. a sodium-potassium alloy with a melting point below room temperature can be used, in which case the filling of the can is effected at a temperature below this melting point.

Title: Improvements in and connected with the super-charging of internal combustion engines
IPC: F02B1/00
Filed: 1925-09-08
Abstract: 263,907. Brown, A. Hall-. Sept. 8, 1925. Pumping machines and fan apparatus; driving- gear; regulating.-A centrifugal governing device controls the starting or stopping of the supply of air to the carburettor of an internal combustion engine from a fan driven by the engine. The fan may be formed on the ordinary radiator cooling fan as described in Specification 263,075, the radiator fan A carrying on an extension a number of blades A<1> which work inside a casing B delivering air to the pipe C. The inlet valve to the carburettor is worked automatically by means dependent on the speed of the engine; (i) as shown in Fig. 5 a centrifugally-moved weight I<1> has a projection moving with lost motion between two stops on a pin J which controls an electric relay for moving the valve (ii) centrifugally actuated weights S<4>, Fig. 9, carry spring-pressed pins S holding the weights in one or other of two positions, the weights through the linkage S<2>, S<3>, moving the valve according to the engine speed. The devices shown.in Figs. 5 and 9 are housed in the hub of the radiator fan. The fan may be driven through a two-speed gear to maintain its delivery approximately uniform with wide variations in speed of the engine. This gear comprises two trains of spur wheels V<1>, V<4>, and V<2>, V<3>, Fig. 10, the wheels V<1>, V<2> being fast on the fan shaft T<1>. The other two wheels are loose on a shaft U<2> driven from the engine shaft having fixed thereon a disc carrying two centrifugally actuated pawls X<1>, V<1>, Fig. 11. With the engine speed low the pawl Y<1> is in engagement with its corresponding teeth on the wheel V<3> and the multiplying gear is in use ; with high engine speed the other train works. Both weights X<2>, Y<2> may carry pawls for engaging both wheels. The weights are interconnected by a spring. When it is desired to run the fan only at low engine speeds it is driven through a double centrifugally controlled friction clutch N<3>, P<3>, Fig. 7. In this device a pulley N' forming one part of the clutch is driven by the engine and carries the centrifugal weights N. The pulley &c. is maintained away from the other clutch part by a spring Q bearing on a fixed bracket Q<1> and on a collar O<2> on the shaft 0 carrying the pulley N<2>. A slide R is free to be moved along the shaft by the pedal R<2>. At high speeds the weights N are out of the path of the slide but at low speeds the weights and pulley N can be moved axially by depression of the pedal. The clutch is then closed and the fan driven through the. bush P<2> keyed to the fan shaft O<1>. A second set of centrifugal weights keep the clutch closed as the speed of the fan shaft rises. If it is desired to work the fan at high engine speeds a bush R<3> is placed between the slide R and a collar Q<5> on the shaft 0.
