Title: Improvements in or relating to circuit arrangements for the starting of gasfilled discharge tubes
IPC: H05B41/19
Filed: 1941-08-20
Abstract: 547,816. Electricity supply for discharge lamps. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Aug. 20, 1941, No. 10639. [Class 38 (iv)] Starting and running circuit for a gaseous discharge tube 1 having preheated electrodes 2, 3 and independent auxiliary discharge electrodes 4, 5 and a ballast inductance in two parts 6, 7. The electrodes are heated at starting by current from the A.C. source through 6, 7 and through the electromagnetic switch 9 which is normally closed. This switch is actuated by the joint action of two coils 11, 12 which aid one another and are connected each between one of the electrodes 4, 5 and a point of the heating circuit which has a potential adequate to initiate an auxiliary discharge each pre-heated electrode and its neighbouring electrode. This auxiliary discharge is initiated when the electrodes 2, 3 have been adequately heated. It passes as a unidirectional current through the coils 11, 12 causing the opening of the switch 9 and, by the resulting inductive kick, starting the main discharge. Since the core of the electromagnetic switch is energized by unidirectional current it is free from A.C. hum and may be cheaply made without laminations. A ballast resistance 19, 20 may be necessary for the auxiliary discharge circuits.

Title: Improvements in or relating to radio receiving systems
Filed: 1928-04-11
Abstract: 307,237. Jackson, L. Mellersh-, (Federal Telegraph Co.). April 11, 1928. Directive signalling.- The directional characteristic of a frame aerial 11 is accentuated to obtain greater selectivity by setting up a long open-ended aerial 24 across the plane of the loop. The aerial 24 may be tuned by a coil 25 either to a particular interfering frequency or to the frequency of reception. The receiver 13 is coupled to the frame aerial 11 but not to the open aerial 24. An interfering wave approaching from an angle 15 is deflected by the aerial 24 into a direction more nearly in line with the aerial 24 and therefore exerts less effect on the frame 11.

Title: Improvements in or relating to methods and apparatus for oxidising coal
Inventor: MCLAREN JAMES
IPC: C10L9/06
Filed: 1956-04-11
Abstract: 844,752. Treating coal. COAL INDUSTRY (PATENTS) Ltd. April 3, 1957 [April 11, 1956], No. 11052/56. Drawings to Specification. Class 50. In oxidizing coal in a fluidized bed in a reactor, the reactor is initially charged with such fine coal that oxidation commences and a rise in temperature takes place up to the normal operating temperature, with little or no external heat being supplied. If the coal is such that 90% passes through a 200 mesh B.S.S. sieve then fluidizing air at 15‹ C. initiates the reaction and raises the temperature, but if coarser coal is used some heat must be supplied. This may be done by warming the inlet air or by inserting a heated surface into the fluidized bed, such as a lowpressure steam heating coil. Alternatively the fine coal may be heated before being fed into the reactor, or it may be charged cold into the reactor and then fluidized with a heated gas other than air. After the fluidized bed has been warmed the supply of heated gas is replaced by cold air and the temperature rapidly rises to normal operating temperature. The fine coal may be obtained from cyclones which remove it from the gases leaving various portions of a plant. In an example Betteshanger H seam coal having less than 5% greater than a 30 and not less than 70% finer than a 240 B.S.S. mesh sieve is fed into a reactor and raised to 110‹ C. by means of a steam coil immersed in the bed. The reaction between the coal and the fluidizing air, which is fed in at atmospheric temperature, rapidly raises the temperature of the bed to 375‹ C. Then coal of the normal grind, 5% greater than a 30 and 25% less than a 200 B.S.S. mesh sieve, is fed into the bed and the reaction remains self-sustaining.

Filed: 1930-04-07
Abstract: 345,520. Weighing-apparatus. SMITH CO., T. L., 1125, 32nd Street, Milwaukee, Wisconsin, U.S.A.-(Assignees of Hart, W. L. ; 696, 58th Street, Milwaukee, Winsconsin, U.S.A.) April 7, 1930, No. 11071. Convention date, April 6, 1929. [Class 143.] A weighing-apparatus, primarily intended for weighing and discharging loose bulk material such as grain, ore, or concrete aggregates, comprises a supporting frame, a weighing cradle carried thereby, a hopper adapted to be supported by the cradle and means carried by the supporting frame for raising the hopper from the cradle. The weighing hopper 9 is supported on a system of compound levers 14, 16, 18, 21, connected to a scale beam. A roller 31 resists the tendency of the hopper to swing inwardly. Near the bottom of the hopper is a discharge gate 34 pivoted on lugs 35. The discharge gate may be opened to discharge the contents of the hopper by rotating a hand-wheel 25 connected to the discharge gate by a sprocket chain 26, a shaft 48 with a flexible joint 46, a crank 38, and a rod 37. The same movement of the hand-wheel, operating through gear wheels 29, 54, shaft 52, crank 55, and slotted lever 57, slides a member 61 along a continuously rotating shaft 59, and presses an undulatory face 64 against the lower end of a lever arm 11a pivoted on a shaft 9b. Lugs 10a on the shaft engage hooks 9a on the hopper and tilt the same into the position shown by dotted lines, thus supporting the hopper prior to loading or to the subsequent agitation described below. Continued movement of the member 61 engages the same with a co-operating clutch member and causes the undulatory face to rotate and agitate the hopper, thus dislodging any sticking material.

Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: FAGARD JULES
IPC: F02M7/04
Filed: 1918-07-06
Abstract: 126,535. Fagard, J. July 6, 1918. Spray carburettors.-An auxiliary nozzle surrounding the main nozzle and fed from a fuel well having a restricted opening to the atmosphere, is connected to a conduit having openings into the well at different heights, so that, as the engine suction increases, the fuel rises in the well above the openings, and more fuel and a stronger mixture pass to the auxiliary nozzle. Alternatively, the auxiliary nozzle communicates directly with the well which is fed through openings at different heights in a conduit supplied from the float chamber. The main nozzle 1 communicates with the float chamber 2 by a passage 3 having a restricted opening 6 into a passage 12 leading to a well 4. This well is open to the atmosphere through a restricted aperture 5, and contains a tube 10 open at the top and communicating through a passage 15 with the auxiliary nozzle 8. Holes 11, at different heights in the tube 10, permit the passage of fuel from the well 4 to the auxiliary nozzle. A pilot jet 21 is also fed from the well 4 by means of two concentric tubes 17, 18, the latter nearly closed at the bottom. The air-supply to the pilot jet is regulated by a screw 22. For use on aeroplanes, the size of the aperture 5 of the well may be varied automatically or mechanically according to the altitude, in any manner. Specifications 103,627 and 105,309 are referred to.

The bar B is gripped and adjusted transversely by jaws 15, 16 by handoperated screws and is adjusted vertically by hand screws. A frame 2 carries rollers 25 vertically adjusted by racks 21 for supporting the end of the bar. A scale 22 is supported by the racks and a stop B adjustable on the scale forms a gauging stop for the bar. In a modification Fig. 8, a bar 69 is positioned in a punching machine 125 on trucks 37, 38. The truck 37 carries adjustable grippers 15, 16 and the truck 38 carries a work stop 67. Rollers 57 adjusted by racks 54 position the bar transversely. After the first hole is punched the truck 38 is secured to the bar by a rod 65 and the truck is moved by an endless wire rope 39 driven by an electromotor or a hand-crank 44. An endless tape measure, not shown, is attached to the truck 38 for indicating the distance between holes. In a further modification a plurality of angle-bars are moved through a drilling machine by two trucks. On one truck is an auxiliary carriage for moving the bars to a position for drilling the first hole and securing the bars by jaws on the truck. The carriage and the truck are then secured together for drilling the rest of the holes.
