Spray carburettors.-The body a comprises an air-inlet portion a<1> to which 1s bolted a straight-through cylindrical mixture-outlet portion b<1> containing a throttle valve b<2> and secured to a jacketed induction pipe b<3>. At the junction of the parts a<1>, b<1> is located a choke tube b with the throat of which an axially movable member c co-operates to vary the air passage past a circumferential row of fuel ducts h<10>. The member c, of streamline form, is mounted on a sleeve c<1> which slides over a column c<3>, the flanged base c<4> of which is removably held in an aperture a<3> by members c<5>, c', c<8>. Movement of the member c is effected by suction in the mixing chamber transmitted through ducts f, chamber f<2> and conduit f<3> to the upper side of a piston e<3> moving in a cylinder e<1> and connected to member c through a rod g, lever g<1>, and a rod g<4> with ball joint g<5>. The piston has a diaphragm e<5> on which presses a spring e<14>, and below the diaphragm is a row of holes e<6> forming a leakage device to prevent sudden upward movement of the piston. A rod i<9> resting on the lever g<1> actuates through a lever i<6> a spring-loaded needle valve i<4> controlling the flow of fuel from the float chamber through apertures i<3> to the diffuser, which comprises concentric tubes h<2>, h<3> in a bore a<4>. The inner tube h<3> is open at its lower end to atmosphere, and the space between the outer tube h<2>, which is perforated, and the bore a<4> communicates with the fuel channel leading to the spraying ducts h<10>. The fuel-valve actuating-lever i<6> is pivoted eccentrically to an angularly adjustable shaft i<8> to permit of the ratio of fuel to air being varied. The float chamber d is roughly of horseshoe form, partly surrounds the mixing chamber and contains a pair of floats secured to a spindle d<2> which actuates the inlet valve.

Title: Spray gun
IPC: B05B1/30
Filed: 1971-01-18
Abstract: 1338162 Spray producers GRACO Inc 18 Jan 1971 [19 Jan 1970] 2249/71 Heading B2F In the airless spraying of liquids such as paint the paint is formed into an annular converging stream by a needle valve assembly 25 in the passage leading to the outlet nozzle 20 of the spray gun, this annular stream, in converging at or near the outlet nozzle, causing different portions of the stream of liquid to impinge and improving the resultant spray pattern. As shown the needle valve consists of a valve stem 39 with a truncated conical section 38 which cooperates with a valve seat 26 to control the liquid flow, the seat having a tapered entrance part and a part with less taper through which the needle valve projects as shown when the valve is closed, the angle of the section 38 of the needle being greater than that of the part of the valve seat 26 with the lesser taper. The liquid to be sprayed is supplied under pressure to the chamber 36 from which it flows as a convergent annular stream into a chamber 22 leading to the outlet 20 when the needle is retracted to the position shown as a broken line in the Figure. The retraction of the needle to open the valve and allow the spraying of the liquid is caused by the pressing of a trigger on the spraying device which is in the form of a pistol (Fig. 1, not shown) the trigger opening an air valve to supply air under pressure to one side of a piston -arrangement to open the valve against the action of a spring, the degree to which it opens being adjustable by an adjustable stop at the rear of the pistol. A safety stop to prevent unintentional depression of the trigger is also provided.

Title: Improvements in or relating to the manufacture of compositions of or containing rubber or similar material
IPC: D06M15/693
Filed: 1933-01-25
Abstract: A carded web or webs of fibre are treated with an aqueous dispersion of rubber, gutta, balata, or the like, either naturally occurring or artificially obtained and vulcanized or not, a coagulant is applied to the surfaces of the single web, or the outer surfaces of a number of superimposed webs, and the whole consolidated by pressure.  The coagulant on the outer surfaces prevents sticking to the press, and may be applied by the press plates, belt &c.  The dispersion is preferably applied by spraying, the direction of the spray being such that the fibres do not tend to be displaced, and it should be of such a nature that it coagulates well under pressure and drying, and should yield a rubber &c. of small extensibility.  According to an example, a face sheet is laid on a belt or drum and wiped with 5 per cent acetic acid, a carded cotton web is sprayed with a mixture of 100 parts of rubber as 60 per cent latex, 3 parts of sulphur, 5 parts of zinc oxide, 0.75 parts of accelerator, and 15 parts of lamp black: the web is placed treated side down on the face sheet and the other side is sprayed: 5 more sprayed webs are superimposed, and finally an acetic acid coated face sheet is applied, and the sheet is rolled under increasing pressure, dried and vulcanized.
