Title: Improvements in and relating to the spinning of bast fibres
IPC: D01H13/18
Filed: 1944-10-26
Abstract: 591,792. Drawing-apparatus for spinning- frames. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., and SUFFERN, W. S. Oct. 26, 1944, No. 20879. [Class 120 (ii)] The invention relates to mechanism for spinning yarns from bast and like fibres wherein the drawing means used are of the type' in which a sliver passes between an endless band and a. co-operating roller situated between two pairs of drawing rollers. According to the invention, the co-operating roller is positively driven and the band is frictionally driven from it, the supporting rollers of the band being freely rotatable and mounted for displacement to free the sliver upon sliver breakage. The supporting rollers 6, 11 for the band 12, are mounted on an arm 8 bearing a weight 9. A balanced rod 18 connected at one end to the arm 8 is held at its other end by a link 19 supported by the yarn passing from the lower drafting rollers to the spinning head. Upon yarn breakage the link 19 moves rearwardly and the rod 18 is struck by a reciprocating striker which pushes it upwards to raise the weighted end of the arm 8 and move the band 12 away from its co-operating roller 5. A feed roller 2 is moved out of engagement with its co-operating roller 1 by a projection 26 on a link 22 attached to the arm 8. The link 22 also causes a brake 21 to be applied to the sliver. The brake 21 is of sufficient weight to hold the mechanism in the inoperative position until it is reset by hand. A conductor 15 may be provided to guide the sliver into the nip of the lower drawing rollers. In a modification the lower drawing rollers are reversed in position and the band is brought closer to their nip, the conductor being dispensed with.

Class 120(2) [Also in Group VIII] Yarn positively forwarded to apparatus in which it is to be utilized at a rate equivalent to and variable with the rate of utilization, is sustained in a free loop immediately prior to such utilization, the location of the bottom of the free loop is sensed and the rate of forwarding is varied automatically in accordance with said location. Low denier yarn 1, withdrawn from a bobbin 3 by a pair of nip rolls 5, of which the lower one is driven by a motor, and passing over a guide 11 immediately to a circular knitting machine, is sustained in a free loop 9 by a stream of air 15 from a nozzle 17; and its position is sensed by dielectric or photoelectric means 25 which is activated if the bottom of the loop rises or falls and which energizes one or other of two controlling circuits, to increase or decrease the motor speed. The loop is protected from extraneous draughts by a casing 13 and may be formed and sustained in or near to the horizontal plane. Conical nip rolls driven at constant speed may be used, the forwarding rate of the yarn being varied by varying the position of the yarn along the nip. Instead of two signal points, only one may be used, the closed end of the loop "hunting" across it. Photo-electric sensing and control means may comprise a constant voltage lamp positioned on one side of the bottom of the loop and a co-acting photo-electric cell on the other.

Filed: 1959-06-24
Abstract: 851,099. Glass tubes or rods. MULLARD Ltd. June 24, 1959, No. 21691/59. Class 56. A glass rod or tube has a precision-formed cylindrical surface adjacent which the glass contains small cavities or bubbles. The rod or tube is shaped with the aid of a metal former containing occluded gas by heating the temperature being such that the gas is given off to form bubbles adjacent the surface of the glass which lies against the former. Preferably a copper or nickel-iron alloy former is used which has been stoved in a hydrogen atmosphere which it absorbs. For a glass tube, a copper rod with precision-formed outer surface is inserted into the tube which is shrunk onto the rod in known manner by gas burners. The rod may be additionally heated by passing an electric current through the rod or by eddy currents. After cooling, the copper rod is placed under tension so that it stretches slightly and is withdrawn. In a glass rod, a precision-bore copper tube with one end sealed has a glass rod inserted and heated till the glass fits the tube. Similar heating and additional heating is used The cooled tube is dissolved away by acid. The rate at which the gas is given off is controlled and may be chosen so that the surface contains half-formed bubbles or round pits. The usual diameter of the bubbles in the glass is from 0.1 to 0À5 mms. but bubbles up to 1À5 mms. are also formed.

Title: Improvements in electrical control systems for machinery more particularly the flying shear control of metal coming from rolling mills
Inventor: NIGHTINGALE JOHN
IPC: B23D36/00
Filed: 1950-09-04
Abstract: 693,447. Electric control systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 19, 1951 [Sept. 4, 1950], No. 21782/50. Class 40 (i) [Also in Groups XXII and XXXVII]. In apparatus for shearing moving metal strip or the like into successive measured lengths, a tachometer generator, the output of which is integrated with respect to time, is driven at a speed proportional to that of the strip, and means are provided to initiate a shearing operation and to start a new integration when the magnitude of the integrated output reaches a predetermined value corresponding to the passage of a desired length of strip. The tachometer generator may be of the A.C. or D.C. type and driven by a measuring roll which is in the path of the strip, an over-run drive rotating the measuring roll so that when it is not engaged by the strip its peripheral speed is slightly less than strip-speed, and when it is engaged it will quickly attain the proper speed. As shown, the integrating device 1D has the signal from the tachometer generator applied to it through lines TG, the required length of strip being set on dials SL. When initially cropping a strip before shearing the first measured length, a flag switch FS is operated by the leading edge of the strip and subsequently causes, after a period which may be adjustable, the substantially coincident initiation of integrator means ID and operation of relay F1C, which starts, through contactor S, acceleration of the motor driving the shears. A contactor TS ensures that the device 1D stops integrating and resets a short time after the flag-switch opens as the end of the strip passes, the contactor F1C (or an alternative contactor 11C) being energised from the device 1D so as to be re-operated at the same period before the second cut as the signal to start integrating was in advance of the first cut. Means are provided for preventing the switch FS from initiating shear operation for cuts after the first, and for stopping false operation of contactor F1C or 11C. Shear-position interlocks are also provided. Two or more integrators may be so arranged that whilst one integrator is re-setting after measuring one length, the next length is being measured by the other integrator, the integrators continuing to function in this manner. Specification 665,380, [Group XXXVII], is referred to.

Abstract: A coating is produced on aluminium or an alloy thereof by treatment with an aqueous acidic solution containing a hexavalent chromium compound, at least one cyanide selected from the group consisting of ferricyanic acid, ferrocyanic acid and their salts, and fluorine and barium contained in one or more compounds.  The hexavalent chromium compound may be chromic acid or an alkali metal bichromate, and suitable ferricyanides and ferrocyanides are the sodium, potassium and ammonium salts.  Fluorine and barium compounds mentioned are hydrofluoric acid and fluoboric acid and their sodium, potassium and ammonium salts, fluosilicic acid and its sodium, potassium and barium salts, barium fluoride and barium nitrate.  The pH of the solution is preferably 0.1-3.0 and may be adjusted using sulphuric, nitric or hydrochloric acid.  Coatings having a colour ranging from clear to yellow, brown and blue may be obtained by varying the pH of the solution and its time of contact with the metal and by incorporating additives e.g. a ferric compound such as ferric chloride to give a blue coating. Yellow and brown coatings may be bleached by dipping in hot water. A dry powder mixture for making up the aqueous acidic solution is disclosed.
