A gun suitable for spraying a liquid or a powder fed to the spray head through a central conduit 8 comprises a duct 24 adapted to supply an atomizing stream of air to an annular outlet 66 surrounding the spray material outlet 50, and a duct 26 also connected to a compressed air supply and arranged to produce at an outlet 82 concentric with the outlet 66 a whirling air discharge whereby to control the spray characteristics. Tangential inlets 78 into a chamber 80 effect the whirling of the said discharge and similar inlet 62 into a chamber 64 may whirl the discharge from the outlet 66. The outlet 50 is generally annular, being defined by a guide or baffle 52, Fig. 4 (not shown) within the conduit 8. The spray material, e.g. paint or a plastics powder, within the conduit 8 is charged by a potential applied to a liner 68 via a conductive strip 70 and a spring 72. A trigger, Fig. 1 (not shown) controls the flow of spray material and air and a push button may be used to selectively cut off the air supply to the conduit 26 so as to decrease the transverse extent of the spray and increase its axial velocity. The air streams from the outlets 82 and 66 may be whirled in opposite directions. A lip or radial or helical vanes may be used adjacent the outlet 82 to improve the stability of the spray. Means may be provided for ionizing the air molecules in addition to, or instead of, the means described for charging the spray material. In the embodiment of Figs. 6 and 7 (not shown) the spray material is discharged as a solid jet, the outlet being controlled by a needle valve. and the air fed by the duct 24 is discharged without whirling via holes in a conductive charging member.

Filed: 1946-09-05
Abstract: 641,223. Belt gearing. BRAMMER, H. Sept. 5, 1946, No. 26726. Drawings to Specification. [Class 80(i)] [Also in Groups VIII and XXX] Flexible material for belting is made by forming a laminated assembly consisting of layers of vulcanizable rubber or like composition with intervening synthetic plastic sheet material which is strong, flexible, and uniformly perforated, subjecting the assembly to pressure to force the rubber through the perforations, and vulcanizing. Gutta percha, balata, or synthetic rubber may be used instead of rubber. The sheet material, which may be of a super-polyamide such as nylon, may be perforated by forming small slits and then stretching to open the slits. Alternatively it may be made by extruding parallel threads or strips of the plastic material and pressing them at intervals so as to join them together to form a perforated layer. The laminated assembly may be formed by coating the perforated sheet material with rubber. A number of the coated sheets may be assembled in laminated formation. Belting may be formed by joining strips of the laminated material in stepped laminated form by vulcanizing or belt link fasteners. The laminated material may be in tubular form. Rings cut in different widths from tubes of different diameters may be assembled to form an endless V- belt. Reinforcing fibres, e.g. of glass, may be included in the rubber composition or plastic sheet.

Abstract: 376,567. Hydraulic shock-absorbers. DELCO PRODUCTS CORPORATION, 329, East 1st Street, Dayton, Ohio, U.S.A.- (Assignees of Chryst, W. A.; 999, Harmon Avenue, Oakwood, Dayton, Ohio, U.S.A.) Oct. 6, 1931, No. 27744. Convention date, June 8. [Class 108 (iii).] In an hydraulic shock-absorber having two compression chambers connected by pressure release valves, the flow of fluid between the chambers is further controlled by a valve which is regulated by hydraulic relay means under the control of the driver of a vehicle. In the apparatus shown in Figs. 3 and 4, the piston 34 is reciprocated by a lever 38 depending from the operating spindle 37 ; and the compression chambers 35, 36 are connected to one another by conduits 60, 62, each having a spring-controlled release valve 66 only one of which is shown. The valve chamber above the valve 66 is connected to the conduit 62 by a transverse opening 70. The end of the lever 38 engages between wear pieces 43 held up by stiff springs 49. The compression chambers are replenished automatically from the central reservoir 30 through passages 50 in the wear pieces and one-way valves 47 held up by light springs 48. The conduits 60, 62 are further connected by a vertical passage 77 controlled by a valve 79 which is screwed up or down to vary the size of the orifice. The valve is adjusted in accordance with liquid supplied to the control chamber 82 through the central opening 86 in the cover at its lower end. The rectangular lower end 81 of the valve 79 engages in the centre of the upper end of a tubular actuator 94 having cam slots 105 engaged by a pin 93 projecting on opposite sides of a non-rotatable stem 92. Vertical adjustment of the stem thus rotates the actuator 94 and the pin 79. The actuator is held up by a spring 101 and a ball race 102 secures free operation. The central stem 92 is raised against the resistance of the spring 91 to an extent depending upon the liquid pressure on the underside of the cup-shaped member 91, the flange 90 of which is connected by a bellows 88 to the cover 83 so as to form a sealed but expansible chamber 88a. The chambers 88a on each of the four shock-absorbers on a vehicle are simultaneously supplied with pressure liquid from a reservoir 128, Fig. 6, through pipes 129. A pump worked by the engine draws oil from the sump and circulates it continuously through passages 124, 130 when the valve 131 is open as shown. The pressure in the reservoir 128 is then small and the shock-absorbers operate with comparatively little resistance. The valves 131 may be adjusted by hand so as to restrict the flow of oil and therefore increase, as required, the pressure in the reservoir 128, with the result that the valves 79 on all the shock absorbers further restrict the passage of fluid between the compression chambers. A connection 134 to a pressure gauge may be provided.

Abstract: 801,579. Mould compositions. NATIONAL LEAD CO. Sept. 11, 1956 [Sept. 27, 1955], No. 27761/56. Class 83 (1). A moulding-sand composition having a green compressive strength of at least 2.4 1b. per square inch comprises sand and minor quantities of a grease thickening agent and a liquid lubricant. The sand component is generally 85-98 per cent of the whole. Examples of grease thickening agents are soaps wherein the positive ion may be an alkali metal such as Na, K, Li, or ammonium, or metals such as Mg, Ca, Zn, Ba, Al or Pb. The anionic portion of the soap may be a long-chain fatty acid such as lauric, palmitic or stearic acid, or it may be a cyclic or polycyclic acid of relatively high molecular weight such as abietic acid, or a rosin-acid generally or a naphthenic acid. Typical grease thickening agents of the soap class are lithium hydroxy stearate, aluminium hydroxy stearate, calcium stearate, potassium stearate, aluminium stearate, aluminium naphthenate and sodium abietate. Another class of grease thickening agents comprises organophilic, organic-treated colloidal silicate materials such as natural or synthetic colloidal clays or zeolite and colloidal silica, e.g. as described in Speciataion 664,830, [Group XXIX], and in U.S.A. Specifications 2,563,555, 2,583,606, 2,584,085, 2,657,149, 2,668,151, 2,693,863 and 2705,206. The liquid lubricant is non-aqueous and of organic character, and examples of hydrocarbons, halogenated hydrocarbons, esters, and silicon derivatives are quoted, reference also being made to those listed in U.S.A. Specification 2,625,508. Finely divided additives of a particle-size 20-100 times or more smaller than the sand-particle size, such as iron oxide, silica flour or other silicate, ground borite, zircon or alumina may be added. Further, when using some of the organophilic organic treated colloidal silicate materials, such as those made from clay, with some lubricants, an activating-additive may allow a reduction in the quantity of clay &c. used. The additives are of low molecular weight and relatively high dielectric constant such as water, ethanol, methanol, acetone, propylene carbonate. Other additives such as powdered gilsonite or tar, comminuted air-blown asphalt, hydrogenated castor oil, carbon black, lamp black, and wood flour may be used. A large number of examples of specific compositions are quoted.
