Title: An improved carburettor for use on internal combustion engines
IPC: F02M7/17
Filed: 1931-12-03
Abstract: 385,722. Spray carburetters. CLARK, E. G., Kynance, Pelham Road, Bexleyheath, Kent. Dec. 3, 1931, No. 33565. [Class 7 (iii).] In a carburetter for an internalcombustion engine in which engine suction operates an annular piston to vary both the amount of fuel issuing from a stationary nozzle and the amount of air to be mixed with the fuel, the fuel passes through an annular vaporizing chamber having downwardly converging walls formed respectively by a conical extension of the piston and a stationary conical member surrounded thereby. The casing d of the induction pipe f supports an annular piston e displaced upwardly in an upper casing d<1> by engine suction acting through a tube x which connects the upper side of the piston with the induction pipe f. The piston e has an upstanding conical porton e<1> leading to a cylindrical top e<2> guided by a similarly-shaped top d3 of a conical portion d<2> of the casing d<1>. The guide d<3> covers air ports e<3> in the piston top e<2> which supports an inner choke tube g and fuel sleeve h. The lower end of the sleeve h surrounds a fuel nozzle a supplied through a tube b mounted in a double conical member c, c<1>, the lower part c<1> of which is in the induction pipe while the upper forms, with the conical portion e<1> of the piston, a mixing chamber. A casing j surmounts the casing d<1> and is formed with air inlets j<2> obscured by a rotatable sleeve i, only small apertures i<1> being left open. The sleeve i is so connected to the piston e that, on starting up, its rotation raises the piston slightly, partly uncovering the ports e3. Fuel enters the sleeve h and is swept off the lower edge thereof by air passing down the space around the choke tube g, the fuel dropping on to the cone c, the surface of which may be grooved or roughened. As suction increases with wider throttle openings, the piston rises and uncovers air ports e<5> in an annular member e<4> disposed between the casings d, d<1>, the air passing to the base of the cone c when a cutaway edge e<6> at the bottom of the piston clears the top of the casing d. In a modification, the lower cone c<1> is omitted, the choke tube g fits closely to the piston top e<2> and the sleeve h is adjustably mounted, a manually-controlled air inlet being provided at the top of the casing j.

Abstract: 1,077,133. Electrophotographic copying apparatus. IWASKI TSUSHINKI KABUSHIKI KAISHA. Aug.18, 1964 [Sept.14, 1963], No.33683/64. Headings G2A and G2H. In an apparatus capable of producing copies by projection printing, on paper which may be used as a plate in off-set printing, a sheet of copy paper 16 is supported on a plate 17 which is moved automatically through charging and development stations and is held stationary at an exposure station b. An original 1 to be copied, at a reduced scale, is supported on frame 3 and illumined by lamps 6, 6<SP>1</SP>. Mirror 9 reflects the image-forming rays from projection lens 7 to exposure station b. Motor 30, or manual means (not shown), may be operated to adjust the scale of reproduction by moving lens 7 through chain drive 30, 31 to screwthreaded rod 29. Cam 34 is simultaneously turned by means of a worm gear and spring 37 moves frame 3, as permitted by cam follower 56, to keep the image in focus. On depressing start button 57, motor 25 is energized to operate chain and sprocket drive 22, 23 and thus move the attached plate members 24 along guide 21 to carry the plate 17 towards the exposure station. Sheet 16 passes beneath magnetic brush 12 and the high tension wires of charging device 13 to effect charging. The engagement of plate 17 with micro-switch 19 de-energizes motor 25 and operates shutter 8 and a timer (not shown) to effect exposure. At the end of the exposure, the timer closes the shutter 8 and starts motor 25 to pass the paper beneath a magnetic brush developing device 15. In this Fig. 3 (not shown), magnetic carrier particles and toner powder are held in a vertically movable tray which is replenished from a hopper. A curtain of vertically hanging bar magnets are supported from a horizontal transversely running endless chain and, in the absence of plate 17, the tray is raised to feed the developer to the magnets. On arrival of the plate 17, the tray is lowered and the toner loaded magnetic brushes engage the surface of the paper. On reaching micro-switch 20 the motor 25 is energized in reverse and the paper passes again beneath device 15. The passage beneath magnetic brush 12, constructed in the same way as device 15 but not supplied with toner powder, is stated to remove surplus toner powder from the developed image. On arrival at station a, the plate 17 operates micro-switch 18 to de-energize motor 25 and the image may be fixed at station a by heating means (not shown). In another form Fig. 2 (not shown), the conveyer run extends at right angles to the direction shown and lies beneath the optical system. Reference has been directed by the Comptroller to Specification 988303.
