Title: Improvements in the manufacture of soap and glycerine
IPC: C11D19/00
Filed: 1931-01-07
Abstract: <PICT:0367513/III/1> p  In a process for making powdered soap and glycerine, a mixture of a fatty oil and the requisite amount of a basic saponifying agent, is passed in a rapidly moving stream through an externally heated narrow tube under pressure, and the saponified mixture is discharged therefrom into a receiver, to form a precipitate of dry soap powder and water vapour containing the whole or part of the glycerine.  A mixture of cotton seed or red palm oil and caustic soda is fed into a tank 1, from which it is forced by a pump 2 in a turbulent stream through a copper coil 3 of small bore, in which the mixture is heated to 250-300 DEG  C. by an oil bath 4, and under a pressure of 800-2000 atmospheres.  The saponified mixture passes through an open throttle 11 and a sprayer 12 into a receiver 5 maintained at a low pressure, by a pump 8.  The resulting dry soap powder is withdrawn from the base of the receiver, and the glycerine and water vapours rise through baffles and are discharged through a tube 13 to condensers 6, 7 also at a low pressure, in which glycerine is separated.  A soap powder containing small amounts of glycerine and water may be made by partially closing the throttle 11, or by maintaining super-atmospheric pressure in the receiver 5, or by interposing a cooling chamber before the throttle.  The soap powder may also be hydrated by treatment with steam.  Rosin may be added to the fatty oil, and the oil and caustic soda may be separately preheated before mixing.  Caustic soda may be replaced by alkali metal or alkaline-earth hydroxides or carbonates e.g. calcium hydroxide, caustic potash, sodium or potassium carbonate, or sodium silicate.

Title: Improvements in or relating to stockings and like articles, and the method of making same
IPC: D04B9/46
Filed: 1938-01-11
Abstract: 509,255. Stockings etc.; knitting. WILDT & CO., Ltd., and ALSTON, L. Jan. 11, 1938, Nos. 863, 17893 and 27282. [Class 141] [Also in Group VIII] A stocking or other hose is produced from a knitted flattened tube or flat knitted fabric, and at each side in the region of the heel and sole fabric is formed with adjacent edges, one at least of which is made by initially cutting the tube or fabric, and one or each of which is outwardly shaped or which are angularly disposed relatively to each other, the edges being subsequently joined to impart a lateral fullness to the heel. In the form shown in Figs. 1 to 3, the edges 5, 5a of the heel fabric 1<1>, Fig. 2, are curved, and the edge 5 is joined to a similarly curved edge 7 of the sole fabric 2<1>, Fig. 3, by a seam 22. The leg, heel, instep and upper toe portions are cut integrally from a piece 8 of tubular fabric, and the sole and lower toe portions from a separate piece 17 of tubular fabric. The sole fabric may be knitted from a heavier yarn than the remainder of the stocking. In a modification, the parts of the stocking are cut integrally from a piece of tubular fabric, and a V-shaped cut substantially i right-angled is made at each side between the heel and sole fabric, the edges of each cut being subsequently seamed together, and the seams extending from the upper area of the heel but not into the lower back and bottom area of the heel. The upper toe portion is reinforced. In another modification, the edges of the heel and sole fabric are joined at each side of the stocking to the edges of an interposed tapered portion which is cut integrally with the sole and heel fabric; the interposed portions may, however, be formed separately. In a further modification, Figs. 8 and 9, each side of the heel is formed with a dart-like portion 68, and a recess 79 is cut adjacent to the heel portion, the edges 72, 73 of the recess being joined to the edges 74, 75 of the portion 68 by seams 70, 71. In another modification, the recess and dart-like portion are formed with curved edges. In a further modification, the heel fabric is furnished at each side with two dart-like portions separated by a V-shaped cut-out portion, the edges of which are joined together prior to joining the edges of the sole and heel fabric. The invention may also be applied to shaping the toes of stockings. The cut edges are joined preferably by forming selvedges by overlocking, blanket stitching or the like, and joining the selvedged edges by sewing, this method replacing the conventional linking operation. According to each of the Provisional Specifications some or all of the edges to be joined may be shaped by machine operation.

Filed: 1971-01-07
Abstract: 1317101 Grinding MINNESOTA MINING & MFG CO 7 Jan 1971 [30 March 1970] 883/71 Heading B3D A method of grinding a planar surface on a workpiece 12 comprises driving an abrasive belt 11 along an arcuate path, holding the workpiece with the plane at which the planar surface is to be formed essentially parallel to the axis of the arcuate path, rotating the workpiece about an axis substantially normal to and intersecting the axis of the arcuate path, pressing the workpiece against the abrasive belt with a pressure not less than 21 kilograms/cm.<SP>2</SP> to move the workpiece towards the abrasive belt, and stopping the movement when the plane is tangential to the arcuate surface. In apparatus for carrying out the method, the abrasive belt is entrained about rollers 17, 19 mounted on a frame 15. Roller 17 is driven by a belt or chain 22 from a motor 21 and has a surface of hard rubber material. Roller 19 is carried by a yoke 18 oscillatable about an axis normal to that of the roller by a piston-and-cylinder device 20 to effect axial reciprocation of the belt and ensure uniform wear of the belt, the operation of the device 20 being reversed each time an edge of the belt passes between pneumatic gauges 27 at each side of the belt. The frame 15 is connected by turnbuckles 39 to a second frame 38 supporting a pair of guide rods 36 along which a carriage 34 is slidable, the carriage supporting bearings 32, 35 for a shaft 31 which is rotatable by a belt or chain 42 driven by a motor 40 and carries a chuck 29 for holding the workpiece 12, such as a casting. The bearing 32 is laterally adjustable by a screw 37 so that the axis of the shaft 31 is not quite normal to the axis of the roller 17. The carriage is movable by an air cylinder 44 towards and away from the roller 17, the forward position being determined by stops 28. The motor 40 is controlled, in accordance with the force exerted by the device 44, so that the pressure of the workpiece against the abrasive belt is at least 21 kilograms per sq. cm. and the depth of cut per half revolution of the workpiece does not exceed a predetermined value. As the workpiece is advanced and the stops 28 prevent further forward movement, the speed of rotation of the workpiece is increased to reduce the grinding time at a lower pressure and prevent surface burning.

Abstract: 365,310. Road signals for controlling traffic. CHANCE BROS. & CO., Ltd. and SPAINK, J. H. ABBINK-, Lighthouse Works, West Smethwick, Staffordshire. Jan. 10, 1931, Nos. 935 and 2006. [Class 118 (ii).] In traffic control apparatus of the kind in which a number of electrically operated signal stations are interconnected, synchronizing mechanism is provided whereby the cycle of operations at any station cannot be repeated until after the completion of the corresponding cycles in the other stations. Each signal station has an electric motor m<1>, m<2>, &c. controlling signal lamps which are all connected in parallel with the same supply terminals l<1>, l<2>, and a rotary contact device c<1>, c<2>, &c. is provided at each station which at predetermined intervals closes the circuit of an operating coil adapted to cause a switch in the motor circuit to be opened and another switch in a synchronizing circuit t common to all the stations to be closed, means dependent on the closing of the synchronizing circuit serving to restart the motors. The operating coil and the two switches associated therewith are all marked s<1>, s<2> in the two stations illustrated. When all the switches s<1>, s<2> in the synchronizing circuit have been closed, the coil of a contactor r<2> in the last station is energized to close a switch r<2> in a byepass of the motor circuit of the last station to be closed, thereby enabling that motor to be restarted. At the same time this coil also closes a switch r<2> in the circuit containing the coil r<1>, which closes a switch r<1> in a byepass of the circuit containing the motor m<1>. Also the coil r<2> closes a switch r<2> in a branch circuit in the last station containing a switch d which by a device operated by the motor m<2> is held closed sufficiently long to keep the coil r<2> in action until all the motors have been restarted. By the motion of the motors the contacts c<1>, c<2> are caused to open the circuits containing the contactor coils s<1>, s<2>, thereby allowing the motor circuit switches s<1>, s<2> to be reclosed by springs, and causing the switches s<1>, s<2> in the synchronizing circuit to be re-opened. Contactor coils and switches t<1>, t<2> are provided to enable the system to continue to work in the event of failure of the signals at any station, a warning lamp w indicating that station. The contacts c<1>, c<2> may operate two or more times in each cycle, if necessary. Specification 354,036 is referred to in the Provisional Specification.
