Patent GB-604139-A (GB)
Title: Improvements in and relating to the treatment of wool-washing effluent
IPC: D01C3/00
Filed: 1945-03-09
Abstract: Wool - washery effluent is treated with sufficient alkali to retard coagulation of the proteins or other nitrogenous bodies so as to prevent the precipitation on heating of these bodies, and the effluent is then heated in an autoclave at a temperature equivalent to a pressure of 50 lbs. per square inch of saturated steam, or thereabout, for a period exceeding half an hour and sufficient to cause the liquor to separate, after heating and being allowed to settle, into three portions, viz. wool grease at the surface, mud or sand at the bottom, and a clear middle layer having detergent properties.  Sodium or potassium carbonate may be used as the alkali for addition to the effluent, and the amount added may correspond to an increase in concentration of alkali such as would be obtained by evaporation of the effluent up to a point at which the minimum content of wool grease in the effluent is 4-5 per cent or thereabout. In most cases, the concentration of potash in the effluent is doubled prior to the heat treatment. The whole or a portion of the sediment may be treated to recover the potassium carbonate or other alkali, and the recovered alkali may be used to treat another batch of effluent.  The wool grease recovered from the treated effluent may be sold directly or subjected to purification treatments.  The middle layer having detergent properties may be used for the wool scouring process and it may take the place of the soap and soda customarily used in such process.  Specification 588,896 is referred to.

Patent GB-716957-A (GB)
Title: Method of and apparatus for the deposition of atomized liquid coating material
Inventor: JUVINALL JAMES WILLIAM
IPC: B05B5/08
Filed: 1951-03-13
Abstract: <PICT:0716957/III/1> <PICT:0716957/III/2> A method of coating a moving surface comprises directing at the moving surface a plurality of annular sprays of liquid coating material each capable of producing on the surface a band of coating material varying in thickness in predetermined pattern from edge to edge of the band, the thickness-patterns of the several bands being generally similar and including areas of different width and the sprays being so disposed transversely of the path of surface movement that a relatively thick portion of one band coincides with a relatively thin portion of another, the several bands complementing each other to create on the moving surface a coating of substantially uniform thickness.  Three annular sprays may be used to give spray patterns on a stationary surface, as in Fig. 3, where the diameters of the circles of maximum thickness of the smaller patterns 32 and 33 lie between 60 per cent, and 90 per cent. of the corresponding diameter of the larger pattern 31, and the patterns 32 and 33 are offset from each other by a distance between 30 per cent. and 70 per cent. of their aforesaid diameters either side of the pattern 31.  When the surface is moved in the direction indicated by the arrow the band of coating obtained is as shown exaggerated in Fig. 4, where the p  band from each spray is shown as well as the aggregate coating of all three sprays which is comparatively even.  Electrostatic sprays may be used, and the sprays may be offset longitudinally of the direction of surface movement as in Fig. 3.  For coating wide surfaces several groups of three sprays may be used arranged so that the side portions of the Fig. 4 aggregate pattern overlap to complement each other.  In a modification a single annular sprayhead may be moved successively and repeatedly through three positions, one being further from the surface than the other two to give a broader pattern, the total effect being equivalent to having a spray in each of the three positions.  Specification 710,852 is referred to.

Title: Improvements in or relating to centrifugal blowers
Inventor: GILES ALAN ROBERT DOUGLAS
IPC: F04D25/16
Filed: 1961-02-20
Abstract: 1,008,734. Centrifugal blowers. PLESSEY CO. Ltd. Feb. 2, 1962 [Feb. 20, 1961], No. 6125/61. Heading F1C. In a centrifugal blower a single wheel is surrounded by a housing which is divided by one or more walls perpendicular to the blower axis, and each of the parts is formed as a volute complete in itself with its own cut-off point, the outlets of the individual parts being angularly displaced relative to each other about the blower axis. An undivided rotor having a central inlet 2 and a set of undivided blades 3 is mounted on a shaft 1 in a housing consisting of two identical volute shells 4 and 5 coaxially secured with their outlets 6, 7 displaced by 90 degrees. The abutting walls form a central partition which, because of the axial inlet air velocity and the guiding effect of the blower wheel backplate, causes approximately 55% of the air to be delivered to the outlet 6. The distribution of the air to the outlets 6, 7 can be varied by altering the relative axial widths of the outlet volutes. More than two outlets can be provided, each having its own volute and separated from the others by a partition.

Title: Improvements relating to the manufacture of crepe fabrics
Filed: 1940-04-08
Abstract: 540,226. Crape fabrics. BRITISH CELANESE, Ltd. April 8, 1940, No. 6300 Convention date, April 22, 1939. [Class 15 (ii)] A crape fabric is formed by subjecting to a crape scouring bath a fabric containing high twist yarn of an organic derivative of cellulose, the fabric containing, and having applied thereto before scouring, a substance of delayed solubility in water, i.e. a substance of a colloidal nature which is not freely soluble in water but which, when treated with water, especially at the temperature of the craping bath, absorbs water and swells. Examples of substances of delayed solubility in water are animal or vegetable proteins, e.g. those obtained from soya beans, gelatin or modified gelatine, or other albumins such as egg albumin, casein and sericin ; proteins which have been treated with formaldehyde or other aldehydes ; gums, e.g. from tragacanth; starches ; methyl cellulose that swells in hot water and alkali soluble cellulose ethers, e.g. ethyl cellulose and hydroxy ethyl cellulose. The yarns are preferably crape twisted under the influence of wet steam or hot water and may be twisted in two or more stages. In an example the fabric is soaked for 1 hour in an aqueous bath at 98‹ C. containing 5 per cent of the isolated protein derived from soya bean and is then heated for 3 hours in a hot scouring and craping bath at 98‹C. Specifications 437,019 438,589, 438,590, 438,591 and 438,654, [all in Group IX], are referred to.

Title: Improvements in or relating to clutches
IPC: F16D11/06
Filed: 1946-03-01
Abstract: 650,931. Clutches. CRAYFORD & BEXLEY HEATH GREYHOUND STADIUM, Ltd., and SOUTHAM, A. A. March 1, 1946, No. 6425. [Class 80(ii)] A driven member 3 loosely mounted on a driving shaft 1, pivotally supports at 3a a pawl 4 which has a laterally projecting lug 4a that can be brought into and out of engagement with ratchet teeth of a member 2 secured to the driving shaft. A control plate 5, loosely mounted on the hub 6 of the driven member 3, has pins 7, 8, 16 secured to it which pass through slots 9, 10, 17 in the driven member 3. A hairpin spring 14 urges a pin 15 on the driven member 3 and pin 16 apart. When a detent 11 is disengaged from a notch 5a in the control member 5, the latter under the action of the spring 14 rotates in a clockwise direction relatively to the driven member 3, and the pin 7 forces the pawl into engagement with a ratchet tooth. In this engaged position of the clutch shown in Fig. 2, the pin 7 holds the pawl from disengagement. To disengage the clutch, the detent 11 which may form part of the armature of an electromagnet is engaged with the notch 5a and the pin 8 disengages the pawl. A detent engaging in a notch 3b in the driven member 3 prevents the latter from rotating backwards. In a modification, the member 3 is adjustably clamped to a driven shaft and the ratchet 2 is provided on the hub of a pinion mounted loosely on the shaft. The clutch is applicable to ticket printing - machines, telegraph transmitters and other apparatus in which a driven member is rotated one revolution.

Title: Improvements in or relating to furnace walls
IPC: F27D1/02
Filed: 1953-03-09
Abstract: 738,321. Furnace walls. SOC. ANON. J. COCKERILL. March 9, 1953 [March 7, 1952], No. 6456/53. Class 51 (2). The walls of a metallurgical furnace, e.g. a melting, refining or heat-treatment furnace, support an independent roof made of bricks supported in a frame, and are so constructed and arranged that the internal surfaces of both side walls are inclined towards the interior of the furnace so as to reduce the span of the independent roof. As applied to a Siemens-Martin open hearth furnace, the inner wall surfaces 3a are curved inwardly, and the roof 4 is supported by suspended beams 4a. This construction inhibits the formation of eddy currents in the gaseous heating stream in the upper part of the furnace. The invention is also applied to a heat treatment furnace with straight sides, Fig. 2 (not shown). The wall surface may be a surface of revolution, e.g. a parabola. In cases where the roof is made of a different material to the walls, material falling therefrom will not attack the said walls chemically.

A radial flow turbine steam chest having chambers for steam at different pressures and temperatures is divided into axially adjacent chambers by one or more helical walls, one of the the chambers being a steam admission chamber having a progressively decreasing flow area from the inlet or inlets and another of the chambers being an extraction chamber with progressively increasing flow area towards an extraction steam outlet. A radial flow turbine steam chest is divided axially by a helical wall 8, Figs. 1, 5, into an admission chamber 9, receiving steam through ports 14, 15, and into extraction chambers 10, 11 bounded by spiral walls 4, 5 and an outer casing 2. Steam from the turbine enters chambers 10, 11 through holes 20, Fig. 2, in the chest end plate 1 adjacent the turbine and is exhausted through pipes 16, 17. Steam is fed to the turbine from chamber 9 through annular passage 18 surrounding inner casing 7 and through nozzles 19 in end plate 1. The flow area of chamber 9 decreases from the inlets 14, 15 and that of chambers 10, 11 increases towards the outlets 16, 17. Leakage from the turbine shaft gland is drawn off through collector 22 and port 24. The walls 4, 5 may be supported from the end plate 3 remote from the turbine. In a modification the steam chest is axially divided into two sections each with its own wall 8 and the space between the walls can be evacuated.

Title: Improvements in or relating to high speed two-stroke internal combustion engines operating with compression ignition
IPC: F02B25/00
Filed: 1940-04-10
Abstract: 540,301. Two-stroke oil engines; valves. RICARDO, H. R. April 10, 1940, No. 6491. [Classes 7 (ii), 7 (iii) and 7 (vi)] In a two-stroke compression ignition engine in which fuel is injected into a combustion chamber E in the cylinder head, an exhaust port in the wall of the combustion chamber is controlled by a "masked" poppet valve G which is timed to close before the piston covers air-inlet ports B<SP>1</SP> on the instroke, so that air supplied by a pump H through a passage K and the ports B<SP>1</SP> continues to enter the cylinder after the exhaust is closed. After the ports B<SP>1</SP> are closed, air continues to be delivered past a rotary valve L into the passage K, where it is stored for use in scavenging on the succeeding stroke. The masking of the valve G is obtained by forming the valve with a cylindrical part G3 which enters a corresponding recess F<SP>3</SP> in the valve seating, and is preferably such that the valve moves for 1/6 - 1/12 of its total lift before the port is effectively opened. The combustion chamber is a figure of revolution about the cylinder axis, and has a mouth E<SP>1</SP> which is less than the maximum diameter of the chamber, but greater than the diameter of the valve, so that the latter can be inserted therethrough. In a modification, the combustion chamber is cylindrical. Specification 125,659, [Class 7 (vi)], is referred to as describing a masked valve.
