Title: Improvements in carburetting apparatus
IPC: F02M69/00
Filed: 1941-09-12
Abstract: 551,926. Spray carburetters. BENDIX AVIATION CORPORATION. Sept. 12, 1941, No. 11734. Convention date, Aug. 3, 1940. [Class 7 (iii)] Fuel is sprayed transversely into the induction passage in the immediate lee of a number of finger-like members extending transversely of the passage so as to act as baffles to the incoming air. The invention is shown applied to a carburetter constructed as described in Specification 523,895 in which two parallel air intakes 17, 18 lead to the induction passage past a fuel nozzle assembly 44. The fuel enters at 48 to an annular chamber 47 and thence through ports 49 past a valve 51, which is opened by the fuel pressure acting on a diaphragm 52. From the lower side of the valve 51 the fuel is discharged through four orifices 80 arranged behind four radial fingers 76, 77 arranged in X- form. As the fuel pressure increases, a piston 70 is moved down to open further fuel orifices 82. The fuel jets impinge on the fingers 76, 77 and by arrangement of the position and curvature of the fingers and the direction of the jets, a uniform distribution of the mixture to the several engine cylinders may be obtained. Air may be sprayed upon the fuel jets by means of orifices 84 supplied from the air intake. In modifications, the baffle fingers consist of arms extending transversely from a fuel-supply tube arranged across the induction passage, the tube being formed with fuel nozzles under the baffles.

Title: Improvements in machines for applying cork tipping or other material to a continuous cigarette wrapper or other strip
IPC: A24C5/58
Filed: 1930-04-14
Abstract: 351,624. Cigarette-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) April 14, 1930, No. 11746. [Class 130.] A strip of covering or other material, e.g. tipping material for a cigarette wrapper, is fed until its leading edge reaches a predetermined applying position and is then held stationary while a severing device cuts from the stationary strip a section which is applied to an adhesive portion of the continuously fed wrapper strip when brought into register with the cut-off section. Means are provided to render the adhesive applying mechanism ineffective when the covering material means fails to feed the covering material, Referring to Figs. 1 and 3, paper P is guided by rollers 13, 14, 15 to co-operating rollers 16, 17 which lead it past a roller 18 to the tobacco feed of a cigarette machine. The cork strip C passes to a roller 27 through a guide 25 and feed rollers 31, 32, mounted on an arm 29 connected to an eccentric pin 35 and as the arm 29 swings on its shaft 28 it periodically stops the motion of the cork strip at a ledger plate 34. A rotating knife 41 attached to a shaft 50 driven by bevel gear from a shaft 36 cuts the strip C and the cut tip projects between the rollers 16, 17 to meet the paper P. The whole of the mechanism is driven from the cigarette machine shaft. Paste is applied to the paper strip P at regular intervals between the rollers 14, 15, the roller 14 having a depression 44 and rotating in a paste receptacle 43, while the roller 15 has a raised portion 47 which presses the paper into the depression 44. The feed-roller 17 has a raised portion 17a which co-operates with the roller 16 to attach the tip C to the pasted portion of strip P. An electromagnet 79 when energized attracts a catch 78 freeing the end of a lever 77 which is then pulled by a spring 81, and lifts the gears on the rollers 14, 15 out of engagement thereby terminating the paste feed. The electromagnet is energized by a battery 85, connected to a contact finger 87, resting on the cork tip C and carried by a periodically swinging bell-crank lever 89 controlled by a cam 93 attached to the knifeholder 51. When the feed ceases the finger 87 contacts with the metal plate 42 and completes the circuit and energizes the electromagnet.

Abstract: <PICT:0494344/III/1> Liquids or mixtures of liquids are distilled by dispersion in another liquid, the boiling point of which is equal to or greater than the boiling point of the liquid to be distilled, and a constant regulation as by controlling the feed is established so as to maintain the composition and temperature of the liquid contained in the boiler; the feed is provided from a constant-level tank, the height of which can be set relative to the boiler, and the setting is subjected to overriding or automatic control based upon the temperature in the boiler.  A boiler 8 is connected by a jointed tube 7 with a constant-level device 3 which is connected in turn by a flexible pipe 2 to the main feed tank 1.  The boiler 8 contains liquid into which new liquid is fed, and the vapours pass away through a pipe 10 to a chamber 11 filled with Raschig rings and thence by a pipe 12 to the condenser.  The device 3 is carried by a bracket 4 with a screw connection to a shaft 23 adapted to be rotated by an electric motor which is controlled by a thermostatic device at the top of the boiler.  Vapours produced in the boiler may be introduced by pipe 15 into the top of the boiler and/or into the chamber 11 to ensure an intimate mixture of the vapours in order to modify the final composition of the distillation product.  The invention is applicable to substances in a more or less fatty, syrupy or pasty state or mixtures thereof with other liquids.

Abstract: 1,254,220. Metalating unsaturated polymers. FIRESTONE TIRE & RUBBER CO. 6 March, 1969 [14 March, 1968], No. 12034/69. Headings C3G and C3P. A polymer containing olefinic or aromatic unsaturation is reacted with an organolithium compound and a compound of an alkali metal other than lithium in which the metal is joined to an oxygen, sulphur or nitrogen atom. The polymer may be a " live " alkali metal compound catalysed polymerization product or it may have been deactivated. Suitable polymers include polybutadiene, polystyrene, polyisoprene, butadiene-styrene, butadiene-isoprene, isoprene-isobutylene copolymers and ethylenepropylene terpolymer. Alkali metal alkoxides, sulphides, amides or hydroxides may be employed as cometalating agent. The metalated polymers may be after-treated (a) with carbon dioxide to introduce carboxyl groups, which may be reacted successively with glycols and diisocyanates to give polyurethanes, (b) by reaction with ethylene oxide to give polyols, (c) by graft polymerization of monomers, and (d) by reaction with polymers containing halogen groups. In examples butadiene is homopolymerized in the presence of n-C 4 H 9  Li and either the " live " polymer or the neutralized " dead " polymer is treated with n-C 4 H 9 Li/t-C 4 H 9 OK and in some cases the polymers deactivated and treated with Si(CH 3 ) 3 Cl, while in others the metalated polymer is reacted with styrene.
