Title: Improvements in gas producers for the continuous preparation of watergas
IPC: C10J3/00
Filed: 1935-06-04
Abstract: 456,671. Water gas generation. COUTTS & CO., 440, Strand, London, and JOHNSON, F., 218, Victoria Drive, Eastbourne, [Representatives of JOHNSON, J. Y.]. -(I. G. Farbenindustrie Akt.-Ges. ; Frankforton-Main, Germany) June 4, 1935, No. 16166. [Class 55 (i)] In the continuous production of water gas, the lower part of the producer is divided by separating walls 3 into a number of narrow gasefication chambers 2 into which the steam is introduced through channels 9 and inlets 10, and from which the ashes are discharged by rollers 8. The steam is heated to 1100‹ C. and the water gas passes up into the wide chamber 11, part being withdrawn through a channel 4, and outlet 5, and part passing through the upper part of the charge the low temperature distillates from which issue with the water gas through an outlet 6. In a modification Fig. 4, the separating walls are provided with heating flues 13 fed from regenerators, the waste hot gases being used to superheat the steam which may be reduced in quantity. A gas suitable for hydrogen recovery may be withdrawn from the outlet 5. To the steam may be added waste gases from destructive hydrogenation of coal, coke oven gases, natural gases or waste gases from the conversion of hydrocarbons with steam. In addition, small amounts of oxygen may be added. To obtain a water gas rich in carbon dioxide, the fuel may be cooled by blowing in non-superheated steam above the gasefication zone proper.

Title: Improvements relating to arrangements for withering tea leaf
IPC: F26B25/18
Filed: 1934-05-30
Abstract: 439,057. Withering tea. MAIN, J. A., Vincent House, Vincent Square, Westminster. May 30, 1934, No. 16178. [Class 34 (ii)] In a method of operating withering trays for tea, the fronts of the trays are lowered from the withering position to a position in which they are spring-supported with the trays at such a slope that the leaf falls from the front of a tray when it is bounced. In the construction shown in Fig. 1, representing part of a tray in the sloping position, the front bar A of the tray is provided on each side with a yoke B connected through a chain C to a wire guide D. The end of the chain is slidably mounted on the guide and is supported by a spring G. The guide is secured to a flange of a support E of right-angled section which carries a series of tray rests F having upwardly projecting portions f spaced from the flange to form seatings for the front bars of the trays when the latter are in the elevated position. The tray rests have squared shanks h passed through square holes in the support E and then turned to lock the rests in position. The back of the tray is pivotally supported near each end on a rear frame upright L, Figs. 5 and 6. A yoke H has its ends passed round a back bar J of the tray and the yoke is engaged by the lower end of a swinging link K, the upper end of which is hooked in a slot in the upright. In a modification shown in Fig. 3, a tension spring R is connected in parallel with links of a chain M so that it resiliently supports the tray in the sloping position although the chain takes the shock of the loaded tray when it is dropped from the elevated position. The spring also acts to hold the tray on the tray rests, when elevated. In a further modification, a compression spring surrounds parts of two oppositely-facing wire hooks with stops for the ends of the spring, the hooks being connected one to an upright frame support and one to a tray front bar. In another modification, springs are used as buffers between the trays.

Title: Improvements relating to electric discharge lamps
IPC: H01J61/86
Filed: 1940-11-12
Abstract: 573,141. Discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., ALDINGTON, J. N., and MEADOWCROFT, A. J. Nov. 12, 1940, No. 16371. [Class 39 (i)] [Also in Group XI] Starting of a discharge lamp of the highpressure mercury vapour compact source type is effected by an auxiliary-filamentary electrode 11 heated independently from a transformer 18, 19, Fig. 5, placed on the lamp side of the ballast 17. The filling has also argon or neon or a mixture thereof at a pressure up to 100 mm. or more. Foliated seals 5, 6, as described in Specification 541,208, [Group XXXVI], lead to the main electrodes 3, 4, the shanks 9 of which are divided by a butt joint to limit heat transfer from the heads 8 to the seals ; the electrodes are tungsten with a thorium or barium compound incorporated and are wound round with tungsten wire 10. The arc is below the lamp centre in a vertical lamp, the upper electrode being heavier than the lower particularly on a D.C. circuit. To maintain the vapour pressure a heater coil may surround part of the bulb and also the upper part of the seal or the latter only, and maintain a local temperature of 750‹ C. To start the lamp the heater circuit is closed by the switch 16 and thereafter is opened to allow full pressure drop across the auxiliary primary 18 which causes rapid ionization of the filling by a discharge between the electrodes 4, 11 ; re-ignition is readily effected when the lamp goes out without the necessity of complete cooling. On a D.C. supply a rotary converter may provide the ionizing discharge, the auxiliary heater being supplied from the D.C. or from an A.C. source. An inductance may be included in series with the lamp which may cause a surge on opening the switch 16 ; the heater coil on the lamp may be used for this purpose. The heater may run permanently. Dimensions of one construction are given with loading. Cooling at the seals may be provided. For use as a projector the lamp is supported by springs 29, Fig. 6, from rods 23 fixed in annuli 21, 22, the springs engaging brackets 27 around the seals ; terminal clamps 31 are provided for the main electrodes and the auxiliary electrode leads are carried to binding screws 26 on the annulus 22. The brackets act as cooling fins for the seals and a jet of water or air may be blown on the lamp. The lamp is mounted with the annulus 21 facing the reflector.

Title: Improvements in or relating to single acting piling hammers or the like
IPC: E02D7/08
Filed: 1945-06-27
Abstract: 595,390. Power hammers. GREEN, N. D., and DEMOLITION & CONSTRUCTION CO., Ltd. June 27, 1945, No. 16401. [Class 83 (iv)] In a single acting drop hammer adapted to rest on the end of a pile and wherein the hammer block is raised by electrically driven means and at a desired point on its upward travel is disconnected from the raising arrangement so as to fall on the pile, the raising arrangement comprises an endless chain carrying a member which co-operates with a trippable lever catch device on the hammer block to raise the block. A casing 39 containing an electric motor 4 and belt driving mechanism for sprockets 15 is normally supported on a pile 40 by vertical rods 3 connected at the bottom by a horizontal rod 29 passing through a groove in the bottom of the hammer block 2. The hammer block 2 is slidable along the rods 3 at the lower end of each of which is a sprocket 17. A chain 16 passes around the sprockets 15 and 17, being driven by the latter from the motor 4. On each side of the block 2 is a pivoted lever 20, one end of which has a bridge piece 23 which normally rests on a roller on the end of an elbow lever 25 pivoted at 27. The other end of the lever 25 engages one end of a pivoted lever 28a. In operation, a projection 18 on the chain 16 engages one end of the lever 20 and thereby raises the hammer block. If the lever 28a is now rotated by a pull on a depending cord 28b, the elbow lever 25 is rotated against the action of a spring to move the roller so that the lever 20 is no longer supported and rotates, thus allowing the hammer to fall. Springs then return the levers to the position shown and the hammer is ready to be lifted by another projection on the chain 16. If the cord 28b is not pulled, the hammer is raised until the lever 28a engages a stop lever 32 carried by the casing 39. The apparatus may be hoisted into position by a chain 37 and be supported and guided by members 35 as shown. In the drawings, the trip mechanism is shown at one side of the block only.

Filed: 1929-05-30
Abstract: 334,512. Jackson, L. Mellersh-, (Aktiebolaget Bofors). May 30, 1929. Mountings.-A field carriage for a high-angle gun is provided with hydraulic elevating gear, the pressure being derived from a pump arranged on the carriage. In the form shown, the elevating pinion E is engaged by a rack forming pan of a piston F<1> working in a pressure cylinder G, the ends of which are connected by pipes g<2>, g<3> to a valve-control chamber H. A hand-pump P drawink liquid from a reservoir Q serves to charge an air-pressure accumulator M when the control valve J is in the central position shown. When the valve J is lowered, the accumulator forces pressure liquid through the pipes m<2>, g<2> into the right-hand end of the'cylinder G, the liquid discharged from the left-hand end passing back to the reservoir Q through the pipes g<3>, q<3>, q'. Similarly, by raising the control valve, pressure is admitted to the left hand end of the cylinder G and liquid discharged from the right-hand end to the reservoir. In the central position shown, the valve, J serves to lock the hydraulic system. A safety valve R' relieves excessive pressure in the accumulator through the pipes R, p<1>. To prevent excessive pressure produced in the cylinder G during recoil from passing to the valvecontrol chamber, a valve is arranged between the pipe g<2> and the cylinder G. The valve is normally kept open by a spring, but closes automaticallv under excessive pressure. Specifications 15837/96, 14933/11, and 25913/11 are referred to.
