Title: Improvements in and relating to re-inforced rubber articles and process of making the same
IPC: B60C11/18
Filed: 1921-01-15
Abstract: 178,898. Brown, J. Jan. 15, 1921. Compound fabric and sheet material.-Indiarubber articles, particularly tyre-treads, are made from a number of strips of rubber vulcanized together, each strip having threads embedded therein extending at right angles to the wearing surface and comprising fibres each of which is separately impregnated with a rubber solution before spinning. Silk is preferred, but cotton, flax, or similar fibres may be employed. The fibre is formed into hanks, washed, dried, and drawn through a bath of rubber solution thinned with alcohol until it will filter through paper. The fibres after drying are spun into threads which are embedded in a thin sheet of rubber 22, Fig. 7 the threads 27 being drawn from bobbins 26 through a comb 28 between rollers 29, 30. If desired, the threads may be coated with a rubber solution before being fed to the rubber sheet. The sheet 22, which is preferably of the same width as the circumference of the tread required, is cut transversely into strips which are superposed and built up into a tread 10, Fig. 4 with the threads normal to the weaving surface and vulcanized together, before or after being built into the tyre. In the form shown the strips are of varying width to produce curved inner or outer surfaces. When cotton or flax fibres are employed, 20 per cent of a solution of bitumen or asphaltum in naptha, gasoline or benzine is added to the rubber impregnated solution. This bituminous solution is also preferably used for coating the threads before embedding them in the rubber sheet.

Filed: 1957-01-23
Abstract: 824,390. Axial-flow blowers. BRUNNER, K. Jan. 23, 1957 [Feb. 8, 1956], No. 2370/57. Class 110 (1). [Also in Group IX] In a travelling blower for textile machinery with separate downwardly and upwardly directed air guides and two concentric sets of impeller vanes, closable apertures are provided between the pressure chamber of the section of the blower housing to which the downwardly directed air guide is connected and the suction chamber of the section associated with the upwardly directed air guide, the downwardly directed air guide being adapted to be throttled. The travelling blower shown is mounted on rollers 34 to run on tracks 35 and comprises an impeller having an inner set of vanes 5 and an outer set of vanes 7. The vanes 5 draw in air through baffles 23, thereby cooling the driving motor 2, and discharge it upwardly through the annular space between baffles 13 and 14. The baffle 13 may be so mounted that it can be offset eccentrically within the baffle 14 to concentrate the annular discharge. The vanes 7 discharge downwardly through nozzles each comprising a swivel joint 9 and telescopic sections 24 and ending in an adjustable orifice formed by two pivoted halves 31, 32. The sections 24, which can be locked into position by clamps 25, may be curved instead of straight so that when they are drawn out they can be turned relatively to one another to bring the discharge orifice to the required position. Further swivel joints 9 and branch pipes may be arranged between sections 24. Throttle valves 22, pivoted about the same axis as the joints 9, allow the flow through each nozzle to be reduced or cut off, the excess air thereby made available pushing open valves 18 and flowing into the suction chamber of the vanes 5 to augment the upwardly directed air stream. Imbricated non- return valves 12 are provided at the suction side of the vanes 7. The valves 18 may also be of imbricated form. The vanes 7 may be mounted separately from the vanes 5 and driven by a separate motor located within the baffle 13. In a modification, the vanes 7 are directly driven by the motor 2 while the vanes 5 are driven through a reverted train of reduction gearing.

Title: Improvements in the heat treatment of metal articles
IPC: C21D9/00
Filed: 1927-01-27
Abstract: 291,483. Hilger, Ltd., A., and Twyman, F. Jan. 27, 1927. Heating by electricity.-In the heat treatment of metal articles e.g. ball races, the article may constitute the secondary of a transformer to whose primary winding is applied an alternating current of low frequency. The feeding of the articles to the transformer, the location of the article in the operative position, and the withdrawal of the treated article may be effected automatically and continuously by electromagnetic force generated by the heating means. The casing 1 is in two parts bolted together through a platform 2 and is provided with a hopper 3 for the heated articles. A reciprocating slide 5 forces the article delivered from the hopper 3 between guides as shown at 16 and between the primary S of a transformer 7, the movable pole 9 of which is held in the raised position by springs 10. When the current is turned on the pole 9 is moved downward to close the gap and the ring 17 is raised, by its repulsion from the exciting winding of the transformer until it surrounds the pole 9. When the current is cut off, the pole 9 is raised and the ring 17 falls. The slide 5 then feeds the next ring into position and pushes the treated ring out through an opening 15 in the casing 1. Quenching liquid floods the floor 2 of the casing and seals up the outlet 15 so that the treated ring passes through a water seal.

Title: Improvements in or relating to looms utilising stationary weft supplies
IPC: D03D35/00
Filed: 1943-02-20
Abstract: 566,922. Shuttleless looms ; woven fabrics. WRIGHT & SONS, Ltd., M., and WILLIAMSON, W. Feb. 20, 1943, No. 2846. [Classes 142 (ii) and 142 (iv)] A loom of the type in which the weft is drawn from a stationary supply and is inserted into successively-formed warp sheds in the form of double picks by a weft-layer which operates from one of the edges of the warp band, is provided with two weft-layers, which enter the same edge of the band of warps, each to insert a double pick, and means for inserting a common selvedge thread through both bights, at the return edge, to lock the double picks. With the batten 10 near its extreme forward position, shedding by dobby or cams is effected. During the retirement of the batten 10, the weft layers 16, 161 are inserted respectively into X, Y of the double shed to project from the return edge of the fabric. The wefts wf<1>, wf<2> thus extend diagonally from the eyes 17 of the weft layers 16, 161 to the fell of the fabric at the selvedge. A finger 32 is now inserted behind the wefts wf<1>, Wf<2> so to draw them towards the fell and provide sufficient space for the passage of a shuttle 30 carrying a binding thread S. The batten 10 now moves forward, the finger 32 is retracted and lowered and the weft layers 16, 16<1> are retracted to lay the second pick of each double pick so that the bight of each double pick extends about the thread S, The weft layers 16, 161 are carried by a rod 15 slidable in the batten and reciprocated by a cam plate, the cam track being formed to give a " dwell " at each end of the stroke of the batten. The pivoted finger 32 is moved in one direction by a truck 36 on the batten contacting a ramp 34 on an arm 35 attached to the finger 32 and in the other direction by gravity. The shuttle 30 moves substantially at right angles to the plane of the warps being housed in a box 38 gapped at 39. The oscillatory motion of the shuttle is derived from two cams which, through sprockets and chains, drive a gear train 41, 42, 43 first in one direction and then in the other, the gears 41, 42 meshing with the shuttle which is sufficiently long to bridge the gap 39 through which the weft layers 16, 161 are projected. The double picks of weft threads wf<1>, wf<2> are interlaced, respectively, with front warps F<1>, F<2> and rear warps R<1>, R<2> and since at each shedding the warps F<1>, F<2> ; B<1>, B<2> ; R<1>, R<2> change places, the warps B<1>, B<2> serve to bind together the double fabric. An inner layer of warps G, the " gut," which is not affected by shedding, may be provided. Some or all of the warps may be of elastic. Specification 566,944 is referred to.
