Title: Improved method of, and means for, manufacturing rovings, yarn or the like
IPC: D02G3/18
Filed: 1946-07-03
Abstract: 615,582. Compound fabrics. BRITISH BELTING & ASBESTOS, Ltd., and ALLEN, G. W. July 3, 1946, No. 19922. [Class 140] Rovings or yarn are made by combining a web or tape of inorganic fibres with a sheet or strip of reinforcing material of a tensile strength substantially greater than that of the web or tape to form a laminated product which, if in sheet form, is divided into tape formation. The inorganic fibres may be corded into a web and then adhered to a sheet, or a web may be divided into tapes and adhered to strips or adhered to a sheet and the sheet divided into tapes The fibres may be rolled before being adhered, and the fibres may be adhered to one or both sides of the reinforcement and more than one layer may be applied to each side. Fibres of different type may be mixed with the inorganic fibres and the laminated tape may be twisted. The reinforcing material may be of paper, manufactured film of rayon, cellulose acetate or other natural or synthetic plastic or thin woven cotton. Specified inorganic fibres are of asbestos, slag, mineral wool, glass silk and glass wool. The adhesive may be glue, gelatine, casein, shellac, rubber or latex. An apparatus for the manufacture of rovings and yarn comprises a fibrous web or tape supply means, means for supplying a reinforcing sheet or strips a device for applying an adhesive to the reinforcement and pressure rollers for pressing the fibres and reinforcement into a laminated product together with splitting means when laminated sheets are produced. Referring to Fig. 1, a fibrous web 1 from a carding engine 2 is led between rollers 3, between which a backing sheet 4 is led after being treated with an adhesive by coating device 5. Modifications are shown in Figs. 2 and 3.

Abstract: 1,39,217. Crystallization by flash-evaporation of a solution. CHICAGO BRIDGE & IRON CO. May 12, 1965 [Aug. 20, 1964], No. 19994/65. Heading BIB. Crystals are obtained by flash-evaporation of a solution of the material in a vessel 10 maintained at a pressure below the vapour pressure of the feed-solution, by introducing the feed-solution into the vessel through a diverging nozzle 18 through which extend longitudinal vanes 34 terminating within the vessel. Above the opening of the nozzle is a depending upper plate 36. Crystal magma flows out of the lower part of the vessel 10, the crystals are separated from the mother-liquor, and the latter is recirculated via a heater to the vessel 10. Fresh feed is added to the hot recirculating liquor before the latter is conveyed to nozzle 18. The design of the nozzle minimizes the deposition of crystals on the inner wall of vessel 10. An apparatus is also described which has four nozzles spaced symmetrically apart around the circumferance of the flash-evaporation vessel. These nozzles are provided with horizontallydisposed vanes. The nozzles may be above or below the liquid-level in the vessel. A multipleeffect apparatus is referred to.

Abstract: 372,165. Feedwater supply systems for steam boilers. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. July 14, 1931, No. 20197. Convention date, July 16, 1930. [Class 123 (ii).] In an instantaneous generator having a centrifugal feed pump 1, to prevent variations in the feed supply due to variations in the boiler pressure, the feed is supplied under constant pressure through a restriction 14 in the pump inlet pipe 3, and a break in the liquid column between the restriction and the pump is maintained by so designing the feed pump that the pressure difference between the two sides at the normal speed of operation is greater than the pressure difference between the maximum boiler pressure and the pressure of the supply to the restriction. The head of water in the supply tank 7, Fig. 1, is kept constant and the valve 14a regulating the restriction may be adjusted by a hand-wheel 16. The feed may be supplied under constant pressure by an auxiliary pump 17, Fig. 2, and the valve 14a regulating the restriction may be operated by the engine governor 23 in accordance with the speed of the main engine 24. A pipe 26 in front of the restriction returns surplus water to the supply pipe through a spring load valve 27.

Abstract: 508,988. Hydraulically operated machine tools ; broaching machines. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.)..July 8, 1938, No. 20295. [Class 69 (ii)] [Also in Group XXII] In a duplex broaching-machine or other machine tool, the slides 10, 11 are simultaneously and oppositely reciprocated vertically by rams 12, 13 working in cylinders 14, 15, the upper ends of which are connected by pipes 20, 21 to a variable output pump P, controlled at will, or automatically, by a lever 30; the lower ends of the cylinders are connected by a crossconnection 22 containing back-pressure valves 23, 27 and a relief-valve 25. A pump P<1> for operating auxiliary services also delivers through valves 51, 53 and non-return valve 55 to the cross-connection 22 to make up losses in that connection. Valve 51 is normally closed, but is opened by a cam-plate 60 on the slide 11 when that is in its lower position ; the valve 53 is normally open, but is closed by a cam-plate 62 on the slide 10 when that is in its upper position. When the slide 11 is at the bottom of its stroke, valve 51 is opened ; if the slide 10 has not reached the top of its stroke, valve 53 is also open, and make-up liquid passes to the cross-connection, until the slide 10 reaches the top of its stroke, thus closing the valve 53 and interrupting the supply of make-up liquid. Any liquid which has passed from the lower to the upper side of the ram 12 owing to downward drift of the slide 10 is, during the re-phasing operation, exhausted from line 20 through a valve 71 which is open when the lever 30 is in the no-stroke position, but which is closed when said lever is moved from that position, that is when the pump is operating in either direction.

Abstract: 1,36,826. Filtering gases. NATIONAL LEAD CO. May 15,1964 [May 15, 1963], No. 20453/64. Heading B1R. A method of treating gases which contain solid aerosols alone or mixed with liquid aerosols and/ or undesirable gaseous components comprises passing the gases through at least one filter of hydro phobic fibres into which, in a direction concusent with the gas flow, is directed a flushing liquid which is non-solvent for the solid aerosols but at least a partial solvent for the undesirable gases, collecting the solid-aerosol-burdened liquid on the downstream side of the filter and discharging the treated gases separately; the filter or the first filter has a thickness of not more than 0. 2 inches. The method may be applied to the effluent gas of the calcination of titanium dioxide hydrate, which gas contains oxides of sulphur, water, sulphuric acid and entrained sub-micron particles of titanium dioxide, the flushing liquid used being water, a weak acid or an aqueous TiO2 slurry. The filters, which may be in the form of flat pads or candles, may be silicone-treated glass wool or preferably a syn-. thetic polyester fibre e.g. "Dacron" (Registered Trade Mark) (polyethylene terephthalate) or "Terylene", (Registered Trade Mark) of which the fibrous diameter is preferably less than 30 Á; the filter or the first stage filter may be 0. 05 and 0. 2 inches thick with a bulk density in the range 2. 0-10. 0 lbs. /cu. ft. While its constituent fibres have a density of 1. 4-1. 5 g per ml. Two filters in series may be used, the first only being flushed, and the flushing liquid being continuously recovered and recycled. In the Figure the gas to be treated and the flushing liquid are directed through inlets 13, 14 respectively on to first filter 16, spent liquid being withdrawn at 15; solid-free gas leaving 16 passes through second filter 17, depositing residual liquid aerosols therein, and is recovered at 19, the liquid residues being removed at 20.

[Class 87 (i)] Ceramic bodies containing much silica and a small content of fusing means and having a very small coefficient of thermal expansion, are made by heating the shaped body to a temperature below fusing point but sufficient to frit the material, and then cooling rapidly to avoid crystallization. For large bodies, parts are made as described above and broken up into small pieces which are then moulded by means of an agglutinant to the form desired, and the body is treated again by fritting and rapid cooling. As an example, a body containing 95 per cent silica, 4À2 per cent alumina, and 0À8 per cent oxides of sodium, potassium, calcium, and magnesium is burnt at 1600‹ C. and cooled quickly. The expansion when reheated to 800‹ C. is 0À12 per cent, or about twice that of quartz glass.
