Title: Improvements relating to weighting motions of looms for weaving
IPC: D03D49/06
Filed: 1925-07-30
Abstract: 249,729. Gledhill, W. July 30, 1925. Letting-off warps.-In a weighting motion of the type described in Specification 198,718, the movable back-rest A is shifted by connection with a warp-feeler lever e<5> so as to reduce the tension on the ruffle-chains b in accordance with the diminution in diameter in the warp on the beam B. The ruffle-chains b are connected to the backrest levers a pivoted at a<1> and to the spring- pressed levers D pivoted at d. A link e having a spring connection with the lever a carries a roller E engaging under the lever D and is adjustably linked at e<1> to the two-armed feeler lever e<5> which is pivoted on a bracket e<4> on the lever D. The chains are fastened to a cranked rod which is pivoted in the levers, D and has a handle for relieving the warp tension. The levers a may be rigidly fixed to a shaft having an outboard arm connected to one suitably-placed lever D. The bracket e<4> may be fixed on the frame and the back-rest may be a roller. In a modification, a shaft to which the levers a are fixed is mounted in one of a series of bearing recesses in the frame and carries an arm linked to the feeler-lever. The roller on the link e contacts with an upwardlycurved surface under the outer arm of a centrally-pivoted lever D.

Abstract: 765,956. Compound sheet materials. DUNLOP RUBBER CO., Ltd. July 6, 1954 [July 14, 1953], No. 19440/53. Class 140. A method of manufacturing belting comprising one or more plies of textile fabric coated with a non-inflammable thermoplastic composition comprises passing the coated ply or plies through hot air to fuse the composition and then cooling the coated ply or plies while subjected to pressure between the peripheral surface of a rotating drum and an endless tensioned steel band following the contour of the drum. A single ply A of belting fabric is coated on both sides with polyvinyl chloride and then passed through a tunnel over rolls 3, heated air emerging from nozzles 2 in ducts 9. The heated air is returned to a heater and recirculated. The edges of the belting ply, are shaped square by passing between spring-loaded U-profiled rollers 10, or alternatively the rollers are encircled by an endless steel band, or the belting ply may have U-shaped, edging strips. The belting ply then engages an endless steel band 4 and passes round a cooled drum 5 being compressed between the band and drum. The band passes round drums 6 and 7 and a tensioning device 8. A belting comprising several plies is made similarly but it travels more slowly.' The roller 3 may be covered with a heat-resistant inert material such as polytetrafluorethylene, or may contact rollers rotating in a lubricant such as a silicone fluid. Specification 762,275 is referred to.

Title: Improvements relating to thermal insulating material
Inventor: SMITH ERIC CHARLES WILLIAM
IPC: C04B28/22
Filed: 1954-07-05
Abstract: Thermal insulating material is prepared by intimately mixing and grinding together lime and a natural silica material, e.g. kieselguhr, and adding the mixture to exfoliated or expanded mineral material which is not finely ground, e.g. enfoliated vermiculite, and heating the composite material in an autoclave to promote reaction between the lime and the silica material. Fibrous material, e.g. asbestos or artificial fibres, may also be incorporated in the mixture to be heat treated.  The preferred mixture consists of vermiculite 49 (parts by weight), asbestos 11, kieselguhr 20, and quicklime or hydrated lime 20, and water. The material may be moulded to form slabs, pipe sections or cylinders which may be used for pipe insulation, e.g. as insulating linings for pipes.  Sheet material having a thin hard face on one or both sides may be formed in a mould, the upper or lower or each face of which is constituted by a cured asbestos cement sheet or a cured sheet having a basis of Portland cement or calcium hydro-silicate.  The whole is treated in an autoclave to bond the insulating material to the sheet or sheets. Alternatively the slab may have one hard face as described the other face being of kieselguhr and lime.  Specification 722,012 is referred to and Specification 708,948 [Group XIII] is referred to in the Provisional Specification.

Filed: 1922-07-18
Abstract: 186,035. Kreiss, A. L. Sept. 13, 1921, [Convention date]. Rotary furnaces; charging and discharging.-Phosphate rock is delivered by a conveyer 6 to a hopper 7 which discharges through a valve 15 and hopper 8 into a rotary tube 1 which is slightly inclined and is lined with refractory material 12 at the discharge end 2. A salt solution is prepared in a tank 9 and fed to a tank 10 which discharges by a valve 11 into the hopper 8 and thence into the tube 1. A pool 14 of solution is maintained in the inclined part of the tube 1, and a reducing flame is projected into the discharge end of the tube by means of a burner 3 in which oil supplied through a valve 4 is atomized by steam supplied through a valve 5. As the tube rotates, ribs 16 lift the phosphate to the hotter upper part from which it falls into a ;pool of solution which causes the pieces to break up so that a suitable mixture of phosphate and alkali salts is delivered into the reaction zone 2, where a clinkered product is produced which may be loosened by means of a poker introduced through an opening 17.

In the embodiment shown in Fig. 1, the mould 26 is provided with two separate cavities and three weighing devices 21 and 22 are arranged so that one of them is positioned on the line through the centre of gravity of one mould cavity, while the other two are symmetrically offset from the centre line of the other mould cavity. The vessel 33 containing the molten metal is provided with four outlets each closable by a plug 34, 35 and discharging into a flow directing member 27, 28, (29), and (30). Either one or two program control members 44 and 45 are provided; in the former case the member 44 controls the operation of all four plugs. Two of the outlets from the vessel 33 are closed before the remaining two so as to reduce the rate of introduction of the metal to the mould during the last stages of the pouring operation. When two program control members are provided the introduction of metal into each of the mould cavities is controlled independently of one another. The mould may be supported by a plate 59 resting on a plurality of rolls 55, the shaft of each roll being supported in a two-armed lever 58 pivotally secured to a shaft 57 mounted on a support 54. Springs 62 extending between levers 58 and fixed members 64 cause an upward force to be applied to the plate 59 on which the mould rests.
