Title: Improvements in or relating to valves for pneumatic tires
IPC: B60C29/04
Filed: 1931-03-10
Abstract: 373,685. Tyre valves. WATSON, F.H., P.O. Box 538, Jonesboro, Arkansas, U.S.A. March 10, 1931, No. 7427. [Class 135.] A tyre valve comprises a stem of yieldable materia which carries means comprising an in sides container for holding the cap, said means extending outside the stem and being of smaller diameter than the stem so that the end of the stem forms a seat for the rim of the cap. The yieldable nature of the stem 1 and the generally tapering configuration formed by the stem 1, a sleeve 9, and the cap 10 facilitate the escape of the entire construction through a hole 5 in the rim 6, in the event of sudden deflation causing the outer cover 7 to drag the inner tube 3 relative to the rim 6. The sleeve 9 which is of smaller external diameter than the stem 1 below its shoulder 14, fits tightly on a rebated portion 13 of the stem 1 above said shoulder, and extends almost to the top of the stem. A bore 23 connects the inner tube 3 with a cylindrical cavity 21 at the top of the stem. A shoulder 22 in said cavity engages the lower part 18 of the insides container, whereon a quick pitch thread is provided. The upper part 17 of the insides container, which is threaded internally and externally, is of larger diameter than the part 18 and is provided with flats to provide a pincer hold. The cap 10 which has a tubular extension of smaller diameter 11 provided with two diametrically opposite slots 12, has an external diameter less than the internal diameter of the sleeve 9, and screws on to the insides container, a leak-tight joint being formed by the rim of the cap and the annular seating 15 formed by the top of the stem and confined between the sleeve 9 and the part 18 of the insides container. A fabric liner 27 extends from the cavity 21 down the bore 23 to the underside of a flap 2 integral with the valve stem 1 and secured to the inside of the inner tube 3. A rounded shoulder 26 at the junction of the stem 1 and' the flap 2 effectively seals the hole 5 when the tyre is inflated.

Title: Improvements in a moving grate
IPC: F23H9/02
Filed: 1929-03-07
Abstract: 331,572. Kr÷pelin, F. March 7, 1929. Grates.-Rotating grate bars are formed by discs a secured on shafts c, non-rotating elements b alternating with the discs being intermittently raised and dropped by projections on the shafts. The discs on adjacent bars interdigitate, the non- rotating elements on one bar occupying space between the discs on the bars on either side of it. The upper surfaces of the non-rotating elements lie below the upper surface of the grate formed by the rollers. Ignited fuel is retained in the recesses d, Fig. 2, formed between the elements b and the discs a, and serves to ignite the fuel passing over it. In the construction shown, the feather c<1> securing the discs a to the shaft serves to raise the sector-shaped elements b, which may be provided with depending members p engaging in guides g, Fig. 9. Interchangeable, spacing- washers e, Fig. 4, between the members a and b allow the air spaces of the grate to be varied to suit different grades of fuel, the members being tapered towards the centre to allow free passage for the ash. The last bar comprises elements a', b<1> larger and more closely set together than the elements a, b of the other bars, these serving to retain the fuel on the grate whilst stripping off the slag. The discs may be formed with teeth to assist their action in feeding the fuel. To enable any discs to be removed without dismantling the remainder they are formed in two parts, those shown in Fig. 9 having a wedge-shaped portion a<3> with flanges o engaging a correspondinglyshaped aperture in the main part of the disc, and removable laterally from it after withdrawing the adjacent sector member b. The disc may then be withdrawn transversely of the shaft, which passes through the gap left by the withdrawal of the portion a<3>. In other forms, the disc is divided substantially diametrically, with engaging parts on the two portions. The shafts may be hollow and water-cooled, the water, after traversing the shafts, being discharged into troughs into which the lower edges of the discs a and the ends of the members p dip. Fig. 5 shows a form of bar in which the members a, b successively decrease in size towards the centre, to form a grate of trough section.

Abstract: The invention comprises aralkylated acyl acetic acid dialkyl amides of formula <FORM:0709854/IV (b)/1> where R1, R2 and R3 are alkyl radicles of not more than 4 carbon atoms and R4 is an aralkyl radicle which may be halogen-, alkyl- or alkoxy-substituted, said aralkyl radicle including any substituents having not more than 10 carbon atoms in all.  They may be made by aralkylating an amide of formula <FORM:0709854/IV (b)/2> in the presence of a basic condensing agent with a reactive ester of an aralkanol of formula R4OH.  Preferably hydrogen halide esters are used, e.g. benzyl halides, which need not be purified before use, thus a mixture of 2- and 4-halogeno-benzyl halides may be used.  Condensing agents specified are alkali metal alcoholates, hydroxides and carbonates in alcoholic solution. Examples are given of the preparation of (1) a -(2-chlorobenzyl; (2) a -(2,4-dichlorobenzyl); and (3) mixed a -(2-chloro- and 4 - chloro - benzyl) aceto acetic acid diethyl amides, b -(2-chlorobenzyloxy) crotonic acid diethyl amide also being obtained in (1). Representative of other specified products are a  - (4 - bromobenzyl), a  - (2,4 - dibromobenzyl), a  - (2 - chloro - 4 - methylbenzyl), and a  - (3,4 - methylene dioxybenzyl) aceto acetic acid diethyl amide and a -(2,4,6-trimethylbenzyl) aceto acetic acid dimethyl amide.  The products are insect repellents (see Group VI).ALSO:Insect repellent compositions contain as active ingredient at least one compound of formula <FORM:0709854/VI/1> where R1, R2 and R3 are alkyl radicles of not more than 4 carbon atoms and R4 is an aralkyl radicle which may be halogen-, alkyl- or alkoxy-substituted and which including any substituents has not more than 10 carbon atoms in all.  They may be used with lower alkanol solvents or diluents as emulsions, dispersions, pastes, creams, powder or aerosols.  Advantageously activators may be present, e.g. 4, 6, 6-trialkyl cyclohexene -3-one-2- carboxylic acid dialkyl and alkyl-aryl amides, especially 4, 6, 6-trimethyl-cyclohexene-3-one-2carboxylic acid diethyl amide.  The production of aqueous emulsions is facilitated by the addition of an emulsifying agent.  A specified repellent comprises 10 per cent a -(2-chlorobenzyl) and 10 per cent a -(4-chlorobenzyl) aceto acetic acid diethyl amide and 75 per cent isopropanol.  Reprehexene-3-one-2 carboxylic acid diethyl amide and 75 per cent isopropanol.

Title: Improvements in door closers
IPC: E05F3/08
Filed: 1936-03-16
Abstract: 472,123. Door operating appliances. ESKILSTUNA JERNMANUFAKTUR AKTIEBOLAG, and NILSSON, S. H. March 16, 1936, No. 7860. [Class 65 (i)] In a spring-closing and fluid check device for doors, the spring 6 is attached at one end to a cover 7 closing the casing 1 and at the other to the piston 3, which is slidable and rotatable in the casing and is rigidly connected to a piston rod 12 projecting outside the casing and connected to the actuating arm 13, the movement of the piston being guided by a groove in its circumference, or in a member connected with it, engaging a pin or the like attached to the casing or a connected member. In the form shown, the groove is formed in the piston, and engages a pin 5 fixed in the casing 1 ; the piston-rod 12 has an axial bore with a ball check valve 15 which is prevented from closing completely by a screwed rod 17 whereby the checking effect is adjusted. The member 7 to which the spring is attached is non- rotatably connected to an outer cover 8 adjustably fixed to the casing whereby the initial stress of the spring may be varied. The groove in the piston may be entirely helical, or may have horizontal ends to allow unchecked motion at the start and finish of the closing movement. The ball 15 may be replaced by a spring plate, and in a further modification the rod 17 has a pointed end forming a needle valve, the piston having a separate check valve away from its centre. The portion of the pin engaging the groove may be formed as part of a screw-thread, to give a larger bearing area, and in this case it is preferably free to rotate in the casing, to accommodate itself to the groove. In modifications of the form shown, the pin is carried by a sleeve fixed inside the casing, and the groove is formed in the piston rod, which is then enlarged, or in a sleeve fixed on the piston-rod, which may then be of different material. The arm 13 may be connected to the piston-rod by a ratchet device. Free movement of the piston at the end of its stroke may be obtained by providing in the piston and the casing wall grooves communicating with the spaces above and below the piston respectively and coming into register at the required position to form a through passage ; if this feature is not desired, the arm 13 is so adjusted relatively to the casing that these grooves never come together.

Filed: 1954-03-19
Abstract: 759,202. Dip-moulding flexible containers. SHAPERO, W. H. March 19, 1954, No. 8018/54. Class 87(2) [Also in Group XVII] A flexible container having a threaded outlet is made by attaching a threaded closure cap (or a former in the shape of such a cap) to a mandrel having the shape of the container, and dipping the mandrel and cap (or former) into a bath of resin, latex, &c., the thread on the cap (or former) forming a corresponding thread on the container. As described, a container comprising a body portion 10, Fig. 4, a shoulder 11 and a screw-threaded closure cap B having a central core 18 that fits into the neck 12 of the container, the material of the body covering the cap, is made by attaching the cap to a mandrel C and dipping the assembly of mandrel and cap into a bath of latex, vinyl plastisol, &c. As shown in Fig. 2 the cap is attached to the mandrel by sliding a bore 19 in the cap over a projection 25 on the mandrel. In operation, first the mandrel (or gangs of four mandrels) is hung on a conveyer 36, Fig. 12, and passes through station I where it is heated, II where the cap is attached, III where the assembly is dipped in a bath 21, IV where the dipped container is heated to cure or set it, and V where it is stripped from the mandrel, e.g. by compressed air passing through grooves in projection 25. During the dipping operation the neck 12 (see Fig. 5) is formed in the annular space between the cap core 18 and the screw-threaded interior of the cap, and a thin skin 16 is formed over the cap: this thin skin may be broken at a sharp edge when the cap is to be removed. The shoulder part 11 of the container is made thicker than the body part 10 by reason of the fact that the corresponding part 23 of the mandrel is thicker than the part 22 and retains more heat: alternatively this thickening may be achieved by dipping at different levels (Fig. 13, not shown). The mandrel may be heated by infra-red lamps 44, Fig. 12, or by immersion (with the cap) in a bath of powdered or liquid material (Fig. 14, not shown), or by gas burner or H.F induction. In modifications:-(1) (Fig. 7) the cap B<1> has a long stem 18<1> which forms a long container neck 12<1>. (2) (Fig. 10, not shown). The cap has a small central pip by which it is attached to the mandrel. (3) (Fig. 8, not shown). The mandrel has air passages for removal of the container by blowing.
