Abstract: 1,077,421. Stacking bricks. METAVERPA N.V. Feb. 19, 1965 [Feb. 26, 1964], No. 7204/65. Heading B8C. Bricks are fed to a stacking and wire-tying machine (10) (Fig. 1, not shown) by means which can turn some of the bricks through 90 degrees so that at least one layer of the final stack is arranged differently from the remaining layers. The bricks are pushed laterally from an endless conveyer (1) (Fig. 1, not shown), or from a reciprocating pusher conveyer (30) (Fig. 3, not shown) to lie in front of a ram (11) (Fig. 1) or (45) (Fig. 3) which pushes them into the stacking machine. The guideway (5) over which the bricks are pushed by the ram (11) can be turned through 90 degrees (Fig. 2, not shown) so that the ram (11) subsequently pushes the bricks in pairs into the stacking machine; these bricks are thus at right-angles to those previously fed. Alternatively two bricks out of each row pushed laterally from the conveyer (30) (Fig. 3) on to a table (32) may be stored between guides (43) while the remainder are pushed into the stacking machine; when the guides (43) are full of bricks they are turned, together with a rotary plate (42), to provide a row of bricks at right-angles to the subsequent rows for pushing into the machine. The stacking machine may be constructed as in Specification 47234/64, and holes may be left in the stack to receive the tines of a lift truck. An automatic control determined by a count of the number of rows of bricks fed may change the orientation of the bricks and the number of bricks in a row as required.

Abstract: 471,816. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., KNIGHT, H. DE B., and DAVIES, L. J. March 10, 1936, No. 7255. [Class 39 (i)] In a device which is operated by alternating - current and is provided with an auxiliary anode adapted to be withdrawn from a liquid cathode to start the main arc, the periods of interruption between the auxiliary anode and the cathode are so adjusted with respect to the frequency of the alternating-current, and the positive voltage to the auxiliary anode is so controlled, that the ignition arc is drawn at least once during each cycle of a desired number of consecutive cycles only of the current, or at least once during each of a desired preselection of such cycles. The envelope 1, Fig. 1, may con. sist wholly or partly of glass or metal and is provided with a starting anode 5 which is held in the normal position by gravity or by a spring which may form the electrode. Its natural period of vibration may be the same as the frequency at which it is to be actuated. A control electrode 8 supported from a stem may be fitted. In another form, the starting anode 10, Fig. 2, is secured through a rod 11 to a flexible metal diaphragm 12 which is sealed through a glass tube 13 to the envelope. When the envelope consists of glass, a metal tube 13 may be used. The external end of the rod 11 is vibrated in the direction indicated by the arrow. Alternatively, the rod 11 may be secured to a corrugated flexible tube 13 through a rigid disc 12. The rod 11 may be inclined to the cathode and its motion may be wholly or partially in the direction of its own axis. Screens may be provided to prevent a discharge to the rod 11 or to other metal parts. The motion of the rod may be produced electromagnetically and may be transmitted through link mechanism located within the envelope. The movement of the starting electrode should be sufficient to allow for changes in the level of the cathode. In other forms, the cathode is movable and the starting anode may be movable or stationary. The frequency of movement of the starting electrode may be higher than that of the alternating-current and the frequency of the voltage applied to this electrode may be equal to that of the alternating-current or to that of the movement of the electrode.

Title: Improvements in or relating to the manufacture and production of cellulosic film
IPC: B29C48/10
Filed: 1940-04-26
Abstract: 540,748. Tubular films. HEAVEN, H. S. April 26, 1940, No. 7570. [Class 2 (ii)] Tubular film, formed by the extrusion of a cellulosic solution into a coagulating bath, is led past a grubbing member or members which make contact with the inner or the outer surface of the tubular body, or with both surfaces, and restrict the flow of coagulating liquid along the tubular body. The rubbing members are supported in line with the spinning nozzle and may be expansible and contractible so as to fit the tube being extruded. As shown a rod 20 extends upwards from the spinning nozzle 13 immersed in a coagulating bath 11 and supports a plug 22 above the level 12 of the liquid in the bath : the plug is hollow and has outer flexible walls 23 which can be expanded by water or other fluid introduced from a pipe 21 extending through the rod 20. A second pipe 121 also extends through the rod 20 and terminates just above the plug for draining the tubular body. The exterior of the tube is rubbed by a scraper or die 25 formed by a circularlyapertured plate surrounding the plug 22 at its greatest diameter : the aperture may be formed by an iris diaphragm so that the diameter thereof can be varied. The scraper may be formed of a cord of circular cross-section or of a tubular rubber ring which may be expanded to vary the diameter of the aperture. A conical shield may be arranged above the scraper 25 to catch any washing water which flows down the outside of the tube and prevent it falling into the coagulating liquid. Two or more plugs and scrapers may be arranged along the length of the tube with provision for the controlled inflation of the plugs and separate tubes may be provided for the plugs for the removal of gas and liquid from the interior of the tubular body.

Title: Improvements in flow divider for fuel system
IPC: F02C7/228
Filed: 1958-03-10
Abstract: 858,147. Supplying liquid fuel to burners. GENERAL ELECTRIC CO. March 10, 1958 [April 2, 1957]. No. 7582/58. Class 75(1). [Also in Group XXVI] A gas turbine fuel system for supplying fuel to a plurality of burner nozzles in which only a first portion of the total number of nozzles is operated over a low power range and other nozzles are cut in and operated over a high power range as the rate of fuel flow to the first nozzles is automatically reduced in response to power increases above cut-in power, has a pair of pressure responsive variable nozzles provided through which the fuel must flow to the nozzles, means being provided for varying the size of the orifices as a function of the power requirements. Fuel from the main fuel pump after passing through a fuel control unit is supplied to the inlet passage 68 of a flow divider 28. After passing through the divider the fuel passes through passages 52, 60 to independent sets of fuel nozzles in the gas turbine combustion chamber. When the engine is shut off there is no pressure in the passage 68 so that the springs 88 and 168 force the control valve pistion 70 and the drainage valve piston 138 to the position shown. In this position, the valve 70 seals off the passages 52, 60 from the inlet passage 68. The passages 52, 60 are connected to the drain passage 98 through ports 48, 58, passages 120, 132, recesses 146, 148 passages 150, 154, passage 152, recess 160, holes 166, space 114 and passage 116. On starting up the engine, the fuel pressure builds up and first moves the drainage valve 138 to the right so that the disc 173 seals off the passage 116 and cuts off the connection between the passages 52, 60 and the drain. As the pressure continues to rise, the piston 70 is gradually forced to move to the right and open, close and re-open the ports 54, 54a, 55, 56, 56a, 62, 62a, 64, 64a. The arrangement is such that with increase of fuel pressure the inlet orifice area to the first set of nozzles first increases. Starting just before the second set of nozzles is cut in, this area is gradually decreased and continues until after the second set of nozzles is cut-in. At this point, the inlet orifice area of both sets of nozzles is increased. The arrangement is stated to improve the atomisation of the fuel nozzles.
