Patent GB-871013-A (GB)
Title: Improvements in or relating to the production of microporous sheet material
IPC: B29C67/20
Filed: 1956-08-31
Abstract: <PICT:0871013/IV (a)/1> A method of producing microporous sheet material comprises the steps of (a) depositing a layer of thermoplastic synthetic resinous particles upon a substantially horizontal, steadily moving, metal band; (b) carrying the layer on the band past first gauging means which compresses it to a desired thickness; (c) carrying the layer on the band past heating means while not subjecting it to pressure, and heating the layer to a temperature sufficient to cause the particles to soften and cohere together; (d) carrying the layer on the band past second gauging means where it is further compressed with the application of heat; and (e) cooling the layer.  A laminate comprising microporous sheet material is obtained by following step (c), above, by the steps of (d) leading a sheet of backing material into contact with the layer's upper surface, under the application of heat and pressure, thus to provide a laminate comprising a desired thickness of microporous sheet material bonded to said sheet of backing material and (e) cooling the laminate.  A suitable composition obtainable in particle form comprises vinyl chloride-vinyl acetate copolymer; a plasticizer (dimethoxy ethyl phthalate, alkyl aryl phosphate and dioctyl phthalate; colour and filler; wetting agent (to aid transpiration through the sheet) and an epoxy resin heat stabilizer for polyvinyl chloride.  In forming microporous sheet the layer of resin particles are deposited from the hopper 6 on to the moving surface 4 and the layer passes through the first gauging means 10, comprising a plate 24 with its surface inclined to the band 14, then through the electrically heated oven 26 and through the second gauging means 12 comprising three sets of two opposed rollers, a continuous band 40 passing round the top rollers.  Electrically heated plates 42 and 44 are fitted, in contact with bands 14 and 40 and arranged at a tapering angle. From the gauging means the layer passes (between bands 40 and 14) through cooling plates 48 and 50, in contact with the bands.  A process and an apparatus for forming a laminate comprising the microporous material are also described (see Group VIII). Specifications 679,549 and 781,983 are referred to.

Filed: 1948-10-13
Abstract: 652,570. Foundations. AKERIB, S. Oct. 13, 1948 No. 26668. [Class 20(ii)] [Also in Group XXI] In order that a silt bed 2 may carry structures such as breakwaters 20, it is consolidated and stabilized by reducing its water and air content. To do this, pipes 4 are driven into the bed at spaced intervals and within these pipes are freely positioned tubes 5 whose entry may be facilitated by pumping water down the tubes to remove any silt which may have entered the pipe. A filter bed 11 is formed around the lower end of each tube by passing a sand and water mixture down either the tube or the pipe, and the pipe is then removed. When each pipe has been removed the tubes are connected to a header 12 leading to a suction system. The suction system comprises a submerged water pump 13 which has an outflow 14 to the water surface, whilst the air is removed since a chamber 15 on the pump 13 is connected to a vacuum pump 17 at water level. The lower end of each tube may be fitted with a screen 19 which is provided with a valve that permits the escape of the sand but which closes on the application of suction so that only air and water can be drawn into the tubes. Sand may be added to the silt before the silt is dewatered and de-aerated. In the Provisional Specification the header may be at or near the water surface level.

Abstract: 334,382. Blaschke, E. Aug. 9, 1929, [Convention date]. Hank-type apparatus; spraying travelling materials.-Apparatus for the wet treatment of skein yarns, particularly artificial silk, comprises bars b which are supported on non-movable rails d and are moved relatively thereto, preferably by the links of an endless chain e, so that they are rotated by frictional contact with the rails to move the skeins through the liquor. Movable rails e may be provided, to which cam and crank means impart a combined up and down and to and fro motion so that the bars are periodically lifted from the rails d. The linear speed of rails e is preferably greater than that of the chain c, and the bars are raised by them preferably when they are moving in the same direction as the chain so that on being lifted the bars are rotated in the opposite direction. At certain positions carrying bands k may be fitted, which preferably travel at the same linear speed as the chain, and are adapted to project slightly above the rails d so that on being raised by them the bars b will have no rotation.

Title: Improvements in hydraulic brakes for dynamometers
IPC: G01L3/20
Filed: 1924-11-11
Abstract: 243,887. Heenan & Froude, Ltd., and Walker, G. H. Nov. 11, 1924. Dynamometers, rotary-absorption.-Relates to apparatus of the type in which a rotor mounted on a shaft is enclosed in an outer casing in which water circulates, and consists in supplying all or a portion of the water to the rotor at a rate of feed proportional to the speed of rotation of the shaft. In Fig. 2 the invention is applied to a reversing type in which there are two sets of oppositely rotating rotors A. Each rotor is hollow and is fitted with a gland a' surrounding the shaft A<2> through which it can draw water from a compartment C in the casing. Water is admitted through branches from a main supply pipe. After entering the hollow rotor, the water passes through holes a formed in the vanes of the rotor so as to communicate with a point a<3> in the power absorbing pockets a<4> wherein under running conditions the pressure is low. The pressure at the points a<3> due to centrifugal force is higher than where the holes a enter the pockets and this pressure is transferred to the space d between the rotor and the casing. The water is conveyed through a passage e, a valve E of variable opening, and passage e' to the compartment C which is fitted with a spring-loaded valve which discharges waste water when the pressure in the compartment C exceeds a predetermined figure, Between the main inlet valve and the compartment C a piston valve G may be inserted normally closed by a spring and acted upon opposite sides by pressures from the chambers d and C. Thus when the pressure is sufficient the valve opens and admits fresh water to keep the temperature within limits. When power is removed from the brake the valve closes. In a modification for a non-reversing type the water is supplied through a regulating valve by a pump driven from the dynamometer shaft. Specification 24949/10 is referred to.
