Title: Improvements in apparatus for washing or scrubbing gas
IPC: B01D47/16
Filed: 1928-04-10
Abstract: 317,412. Clapham, T. A. April 10, 1928. Scrubbers and washers.-Gases are washed in rising through a tier of chamber on a vertical shaft which, on rotation, raises the washing liquid in a sleeve and spreads it over the upper surface of packing material in each chamber. Gas rises through openings g into chambers a with concave bases c collecting the descending liquid, which enters apertures 12b in the base of a stationary sleeve 12. The water is guided by ribs on the base c and on the underside of a plate 11 thereon and is raised in a rotary sleeve 9 by inclined slots 8a of members 8, k rotating with the shaft. The rotary sprays of water projected from the top of the sleeves 9 by nozzles 10<a> over laths of wood or trellis work in the chamber a are broken against projections c<5> on the underside of each base c.

Title: Improvements relating to continuous lasers
IPC: H01S3/07
Filed: 1965-03-12
Abstract: 1,098,342. Lasers. COMPAGNIE FRANCAISE THOMPSON HOUSTON - HOTCHKISS BRANT. March 12, 1965 [March 12, 1964], No. 10543/65. Heading H1C. The continuous outputs of an assembly of parallel gas laser elements excited from a common R.F. source are combined and synchronized by locating the elements in a common optical cavity, the reflecting system of the cavity providing light paths between the various elements. Four gaseous laser elements T1-T4 are shown in Fig. 1 which are positioned between two spherical, partially-transmitting reflectors M, M<SP>1</SP>, the parallel output beams of the laser elements being focused on the centres of curvature F, F<SP>1</SP> of the reflectors by lenses L, L<SP>1</SP>. Part of the light passes through the mirrors and is corrected into a parallel output beam by external lens systems, not shown. Due to diffraction some of the light emitted by a laser element is reflected back to another element and synchronism of the oscillations is obtained. Optionally, apertured diaphragms D, D<SP>1</SP> may be located at the centres of curvature F, F<SP>1</SP>. In a modification, Fig. 2 (not shown), the spherical mirrors are replaced by plane parallel mirrors P, P<SP>1</SP>. A further embodiment is described, Fig. 3 (not shown), in which the laser elements are enclosed in a tube To containing a heliumneon mixture and having parallel windows B, B<SP>1</SP> positioned at the Brewster angle. The elements are in staggered parallel relationship with their ends equally spaced from the windows. The elements have common excitation electrodes E1, E2 which also serve as thermal conductors, and the laser elements comprise thermally conducting tubes formed, for example, of beryllium oxide.

[Also in Division H2] In a reciprocating fuel pump comprising a pumping plunger 32, the output shaft 15 of the drive 14 is connected to the crank-shaft 16 by a resilient coupling 17 and the crank-shaft and a sleeve 23 journalled on the crank-pin are biased in a direction away from the pumping plunger. The sleeve and crank-shaft may be biased by a U-shaped coil spring (38) Fig. 2 (not shown). In a further embodiment, Fig. 4 (not shown), the sleeve and crank-shaft are biased by the action of the piston (73) of a vacuum pump connected by a line 76 to a vacuum reference control of a fuel injection system. The vacuum pump piston (73) is formed with an annular groove (79) which houses a unidirectional sealing ring (80). The plunger 32 carries a rubber cap 35 and is biased against the sleeve 23 by a spring 36. The plunger is held against the bias of the spring 36, when the delivery pressure in pumping chamber 31a rises, to decrease the plunger stroke. Vapour is vented to the fuel tank 56 through a connection 58 to the pump inlet containing a float valve 59.

Abstract: Sodium carbonate monohydrate is prepared from light soda ash by a continuous process comprising maintaining in a crystallizing zone a slurry of (a) an aqueous mother liquor saturated with sodium carbonate and having dissolved therein 3-17% by weight of sodium chloride based on the weight of the mother liquor and (b) 30-65% by weight of solid sodium carbonate monohydrate crystals, based on the entire weight of the slurry, the slurry being maintained at a temperature below, but not more than 20 DEG  C. below, the transition temperature for conversion of sodium carbonate to anhydrous sodium carbonate and being agitated so that there is at least 30% by weight of solid sodium carbonate monohydrate in any part of the slurry; continuously feeding light soda ash to the slurry at a rate of 800 to 4800 gm. per hour per litre of slurry; continuously discharging part of the slurry and classifying the discharged slurry into a second slurry containing smaller crystals of sodium carbonate monohydrate and a third slurry containing larger crystals of sodium carbonate monohydrate; recycling to the crystallizing zone at least part of the second slurry and separating crystals of sodium carbonate monohydrate from the third slurry and recycling at least part of the mother liquor to the crystallizing zone.  The monohydrate may be dehydrated to produce dense soda ash.  Alternatively the light soda ash may be added as a slurry prepared by (a) mixing light soda ash with mother liquor (b) evaporating sodium carbonate or sodium carbonate-sodium chloride solutions at temperatures above the transition temperature or (c) decomposition of sodium bicarbonate suspended in an aqueous solution containing sodium carbonate, sodium bicarbonate and sodium chloride.  The slurry may be added above, at, or slightly below the monohydrate/anhydrous sodium carbonate transition temperature. Temperature control may be achieved by, for example, controlling the temperature of incoming materials by circulating through a water-cooled heat-exchanger, by blowing air across the surface of the slurry, or by circulating part of the slurry through a flash tank maintained at a pressure below that of the crystallizer.

Abstract: 580,285. Regulating. FOX, V. A. June 6, 1944, No. 10858. [Classes 7 (ii) and 7 (vi)] In a regulating arrangement in which the rate of acceleration of a diesel or a petrol engine is controlled by connecting the accelerator pedal to a dashpot device, a leak-off therefrom is connected to the induction pipe. The dashpot device comprises a piston 12 having a cup-washer head 13 of leather or rubber which when forced to the right by a spring 16 draws fluid, e.g., lubricating oil, upper cylinder lubricant, diesel oil, water or a mixture of water and alcohol past a non-return valve 15. Sudden movement of the piston to the left by depression of the accelerator pedal is resisted by escape of the fluid through orifices regulated by tapered screws 21, 23 which allow the fluid to return by passage 22 to the source of supply, and to flow by a passage 24 to the induction pipe. The passage 24 preferably leads to a nozzle which feeds the fluid on to a wool, cotton or felt strip wrapped with wire and extending across the induction pipe. An adjustable stop 26 limits the movement of the piston. The casing 40 may be attached to the dashboard of the vehicle, the piston 12 being operated by a cable passing round a pulley on the end thereof and attached to the accelerator pedal linkage.
