Title: Process and apparatus for reducing the power required for the mechanical treatment of movable masses
IPC: C10B19/00
Filed: 1937-05-31
Abstract: 501,835. Reducing friction by electric current. SIEMENS - SCHUCKERTWERKE AKT.-GES. May 31, 1937, No. 15133. Void. Convention date, May 29, 1936. [Class 41] The power required for the mechanical treatment of materials is reduced by passing an electric current through the material during treatment, the current being insufficient to cause any evaporation of moisture. Either direct or alternating current of low or high frequency may be employed. Preferably a low voltage is used with a current density of about 1 amp. for each half square metre of treating surface, the current being automatically maintained constant. In pressing coal briquettes, clay, rubber, &c. the die may form one electrode and the mould the other, or an electrode dipping in the material may be used. In drying furnaces of the plate or drum type, current is passed between the plate or drum and a stripper or worm working therein for conveying the material through the apparatus. The current is said to reduce friction and also assist the drying by transferring moisture to the surface. In pile driving or extracting, the pile forms one electrode. while the other is earthed. Alternatively two electrodes in the earth or two piles may be used. In mixing, kneading, or agitating apparatus for ceramic, chemical, or food materials using blades or worms, the casing forms one electrode and the worm &c. the other. Alternatively a separate electrode may dip in the material or two blades may be insulated and used as electrodes. In drilling for oil &c. the drill acts as one electrode while the other is earthed or two drills may be used. In dredging earth, coal, &c. the grab or scoop forms one electrode while the other is earthed. In storage containers, silos, or shoots for ceramic material, coal, chemicals, &c. an electric current may be applied between the wall of the container and an electrode dipping in the material to reduce the friction during discharge. In worm or chain conveyers also a current may be passed between the conveyer and the material carried thereby. In separating coal, ore, &c. a current is passed between the material and the screen.

Title: Improvements in or relating to a process of polymerising acrylonitrile
IPC: C08F20/44
Filed: 1953-06-01
Abstract: Acrylonitrile is polymerised in an aqueous saline medium which is a solvent for the monomer and for the polymer and which contains from 0.02 to 1 part of copper ions per million parts of saline medium.  As salts there may be used zinc halides, stannic halides, and calcium or sodium thiocyanate, or mixtures of salts such as mixtures of zinc chloride with lesser amounts of calcium or magnesium chloride, zinc bromide with lesser amounts of lithium chloride, and sodium thiocyanate with lesser amounts of potassium thiocyanate.  The copper may be present as an impurity in the salt, or may be added as cupric chloride.  Polymerization may be carried out in the presence of hydrogen peroxide or ammonium persulphate as a catalyst.  The molecular weights of the acrylonitrile polymers produced are a function of the concentration of the copper ions, higher concentrations of copper ions giving rise to polymers of lower molecular weight.

Title: Improvements in, or connected with, the jacquard apparatus of looms
IPC: D03C3/24
Filed: 1921-06-04
Abstract: 185,236. Southwell, Ltd., H. & M., and Head, T. W. June 4, 1921. Pile fabrics.-Relates to the weaving, with jacquard apparatus, of carpets &c. having a design symmetrical relatively to a line parallel with the warp, the apparatus being of the type wherein each vertical row of holes and spaces on a card contrcls two or more contiguous sets of coloured warp threads. According to the invention, after the cards have been used for weaving a patterned part of the fabric on one side of the said line, they are reversed and used in a separate operation for weaving the symmetricallypatterned part of the fabric on the other side of the said line: or, alternatively, both parts of the fabric are woven at the same time by using pairs of cards similarly perforated, as shown in Fig. 4A, and simultaneously employed the cards in each pair being reversed end to end with respect to each other. In both cases, the jacquard needles or connections are specially arranged to suit the manner of using the cards. Thus, in the case illustrated by Figs. 1, 2, and 1<A>, where each vertical row of holes and spaces on a card e controls two contiguous sets of coloured threads bv means of the needles a having eyes a<2>, a<3> controlling the thread-lifting cords b, each set comprising a white thread W, a blue thread B, a red thread R, and a green thread G, the upper four horizontal rows of needles may be arranged to control the left-hand or outside set of each pair of sets of coloured threads, the lower four rows controlling the righthand sets, commencing from the left until the centre of the jacquard is reached, as shown by Fig. 1 and the left half of Fig. 1A, after which the upper four rows of needles control the right-hand sets, as shown by Fig. 2 and the right-hand half of Fig. 1A. With the jacquard connections so arranged, when the card is reversed end to end and again used in the jacquard, the fabric produced is, as shown in Fig. 1<B>, symmetrical in pattern with that first produced. In a modification, the cords b themselves are arranged to produce the required result by crossing certain of them, whilst others extend straight downdownwards. An arrangement is described wherein two cards are used in weaving a line in half a symmetrical pattern. Also the weaving of the whole of a symmetrical pattern at one operation is described'. In certain cases, a quarter only of a carpet may be woven at one operation. The coloured threads may be selected by means of holes instead of blanks, and four horizontal rows of holes and blanks may be arranged to control the selection of five colours. An arrangement is also described wherein the cards are reversed in such a manner that what were formerly lower edges become upper edges, a corresponding readjustment of the jacquard connections being made.

Title: Improvements in and connected with printing or recording mechanism for weighing apparatus
IPC: G01G23/18
Filed: 1923-06-18
Abstract: 218,470. Pooley & Son, Ltd., H., and Dobson, J. June 18, j923. Printed records, apparatus for giving.-A member 15 controlled by a moving part 7 of the scale mechanism effects the locking of the printing handle 10 when there is no load on the scale, and frees the handle when a load is applied to allow one record to be made. When there is no load on the scale, the projection 7<a> on the weighbeam 7 keeps the arm 15 depressed so that a stop 14 carried by the arm engages a projection 13a on a lever 13 carried by the spindle 11, on which is mounted the operating handle 10. On a load being applied, the projection 14 is lowered to allow the projection 13<a> to pass over it when the handle 10 is operated. One complete rotation of the handle 10 serves to effect a record by pressing a ticket against type carried by a quadrant 8, and the arms 13, 16, on the spindle 11 are carried round until the arm 16 strikes the projection 14, if the load still remains on the scale, a spring 17 being compressed. Backward movement of the handle 10 is prevented by a pawl 18 and ratchet-wheel 19 and a further record cannot be obtained until another load on the scale releases the arm 16. If the load has been removed from the scale when the arm 10 has made one complete revolution, the arm 13 engages the projection 14 and prevents further operation.
