Title: Machine for inserting valves in inner tubes
IPC: B29C65/00
Filed: 1929-11-21
Abstract: 337,234. Firestone Tyre & Rubber Co., Ltd., (Firestone Tire & Rubber Co.). Nov. 21, 1929. Inserting and fitting valve stems to air tubes.-A valve-inserting machine for pneumatic tyre tubes comprises an anvil 10, Fig. 2, and a relatively movable element 16 supporting a valve V in an inclined position on the anvil prior to raising it into a vertical position, Fig. 7, for fixing in the tube T. The device is preferably combined with a known punching apparatus 25. The anvil 10 is supported at one end on a bracket 11 and at its outer end has a die 12 for co-operation with a punch in the apparatus 25. A seat 13 is formed in the anvil 10 with a notch 15<a>, Fig. 7, to receive the edge of a valve base to allow the valve V to recline in a groove in the movable element 16, which has a forked end 17 to engage the valve. The element 16 is actuated by a plunger driven by fluid pressure in a cylinder 21, Fig. 2. The bracket 11 has an arm 24 supporting the punching device 25 provided with an annular cutter having a guard 40. The cutter is driven by a belt 43 and is brought into operation by a lever 36. The valve inserter includes a cylindrical member 46 adapted to embrace a tyre valve and formed with prongs 47 insertable in the valve opening of the tube to position the opening over the valve seated at 13. The inserter is mounted on a crosshead 48 reciprocable on guides 49 and operable by a piston in a fluid-pressure cylinder. In order to correlate the operation of the elements 16 etc., a valve 56 connected to pipes 22, 23 is controlled by a lever 60 also operating a valve 57 connected to pipes 52, 53 controlling the movement of the inserter 46.

The spikes 5 on a carpet-securing strip of tensile steel have their roots 8, Fig. 5, domed out of the strip plane. The bent-up spikes may be turned about their longitudinal axes as indicated in Fig. 2 and may be slightly helical in shape. The strip may be of stepped form, Fig. 6 (not shown), so that the edge of an underfelt can be secured on the spikes (5) of the lower plate (11) and that of the carpet on the spikes of the upper plate (10). To support the upper plate there may be cut-out portions (14) which may be spiked or have holes for screws (17) &c. or there may be just vertical cut-out portions (16) or mid-width cut-outs. For use with a stair carpet such a stepped strip may have an extension (18) with spikes (5) for the riser of the carpet. An angle-sectioned strip, Fig. 1 (not shown), with spikes (5) pointed across the angle may be used on stairs. A flat strip may have two rows of oppositely-directed spikes for joining two pieces of carpet and the arms of the angle-section strip or the stepped strip may each have more than one row of spikes. The strip may be secured by adhesive, nails or screws or by points secured to or cut out of the strip.

Abstract: 522,404. Chloramines. WESSANEN'S KONINKLIJKE FABRIEKEN N.V. Dec. 10, 1938, No. 36085. Convention date, Dec. 28, 1937. [Class 1 (ii)] Chloramines, in particular nitrogen trichloride, are prepared by causing gaseous chlorine to act on an aqueous solution of ammonia or an ammonium compound in the presence of a current of inert gas which removes the chloramine, the whole of the operations taking place in a single apparatus. In order to prevent the accumulation of the acid produced in the reaction, water or an alkaline substance may be introduced into the apparatus, excess liquid resulting being removed by an overflow device. Ammonia gas or a solution thereof is suitable for this purpose ; when gaseous ammonia is introduced the inlet point is separated from that of the chlorine by a porous partition. Other basic substances may also be used e.g. sodium hydroxide or carbonate solutions or lumps of calcium carbonate. Other chloramines may also be produced according to the method. Specification 533,404 describes an apparatus suitable for the process.

Title: Improvements in tipping waggons
IPC: B60P1/16
Filed: 1929-11-26
Abstract: 334,797. Wirz, E. Nov. 26, 1929. Tipping carts. - In wagons adapted to be tipped to either side or to the rear by means of an hydraulic apparatus the movement of the latter is transmitted to a single valve controlled by an inclined surface to limit the stroke of the apparatus. The hydraulic apparatus comprises a ram and a cylinder having a spherical foot or lower portion. A strap 10, Figs. 1 and 2, having an inclined plane, is adapted to rock on a pivot 12 and is provided with an extension 13 provided with a stud 14. Movement of the strap 10 about the pivot caused by the inclination of the hydraulic apparatus at the limit of its stroke opens the valve 4 and allows the pressure within the chamber to be released and the oil to escape through the pipe 9 to return to the tank. In the modification shown in Fig. 3 three projections, of which 21, 22 are two, are provided on the spherical foot of the hydraulic apparatus. At the limit of the stroke in any direction one of the projections operates the lever 10 through inclined planes or surfaces 18, 19 to operate the valve 4. In a further modification, the valve 4, Fig. 4, is directly operated by coming in contact with one of three planes 26 arranged in the chamber 25. In another case, stops on the cylinder depress one of three plungers which by means of inclined planes or surfaces cause a ring to rotate and operate the valve.
