Title: Improvements in or relating to the spinning of textile yarns
Inventor: CATLING HAROLD
IPC: D01G23/06
Filed: 1962-04-25
Abstract: 995, 652. Preparing fibres for spinning; spinning processes. COTTON, SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. April 25, 1963 [April 25, 1962], No. 15699/62. Headings D1F and D1N. [Also in Division G3] In apparatus for spinning textile yarns from fibrous material, two or more machines selected from a group consisting of a hopper feeder, a scutcher, a card, and a drawframe, act on the material in sequence, and deviation of a measured property of the material processed in one machine controls the adjustment of preceding machine at a corresponding rate to reduce the deviation. In Fig. 3 fibrous material to be spun is supplied by a spiked lattice 11, an evener roller 34, and a feed roller 12 to a tower hopper 13 the output of which is conveyed by a horizontal lattice 14 to a scutcher comprising a feed roller 15, a beater 17, cages 18, 19, calendar rolls 20-23, and lap rollers 24, 25. Variations in the thickness of the material passing through the calendar rolls are detected by vertical movement of roll 20 and a transducer 28a produces a proportional electrical signal which, after amplification at 29, controls a servomotor 30 adjusting evener roller 34 and the cross-section of tower 13 to correct the thickness. Variations in the thickness of material passing roller 15 are also compensated for by the consequent movements of a pedal assembly 39 which adjusts through a cam-ended lever 41, a variable speed drive 37 for roller 15. The output of a differential gear 45, responsive to the relative speeds of the scutcher drives, controls the mechanical advantage of, and position of the fulcrum 43 of, lever 41, so that the average degree of modification of the material passing through the scutcher is maintained constant. The fulcrum of lever 41 may alternatively be adjusted both vertically and horizontally by the differential gear through a pin and slot machanism. Modifications are described in which the tower hopper, the pedal control, and/or the evener roller are omitted. Measurement of thickness by the effect of the material on radiation or capacitance is referred to. Specification 936,178 is referred to.

Title: Improvements in the production of metallic compounds of azo dyestuffs
IPC: C09B45/01
Filed: 1927-06-13
Abstract: 272,908. I. G. Farbenindnstrie Akt.- Ges. June 15, 1926, [Convention date]. Azo dyes, soluble metal compounds of.-Metal compounds of azo dyes which are insoluble or difficultly soluble in water are obtained in good yield by treating the dyes with suitable metal compounds in the presence of such amounts of water soluble organic solvents as are capable of dissolving a substantial proportion of the dyes. The process may be carried out with or without the application of pressure. The following solvents are specified :-mono- or poly-valent alcohols, e.g. methyl, ethyl, propyl and butyl alcohols, glycol and its esters or ethers, polyglycol, and glycerol, also ethylenechlorhydrin, triethanolamine, thiodiglycol, phenols, and acetone and other ketones. Mixtures of solvents may also be used. In examples the azo dyestuffs from p-chlor-o-aminophenol and #-naphthol or 1-phenyl-3-methyl-5,-pyrazolone are heated in an autoclave with ethvl alcohol and chromium formate to produce the chromium compounds; the copper compound of the first mentioned dyestuff is also obtained by using copper formate instead of chromium formate. The ethyl alcohol may be replaced by acetone or by a mixture of methyl and benzyl alcohols.

Title: Improvements in stop-feed mechanism for lathes and like machine tools
IPC: B23Q11/04
Filed: 1936-06-05
Abstract: 461,793. Lathe &c. feed - motions. KOENIGSBERGER, F. June 5, 1936, No. 15745. Convention date, June 24, 1935. [Class 83 (iii)] A stop-feed mechanism, for lathes or like machine-tools, of the kind in which a rotatable feed nut is normally held against rotation by a clutch device which is automatically released by an overload, has a separate displaceable jamming device normally disposed between the periphery of the nut and a resilient stop for holding this device so that it is instantly displaced to a declutching position as soon as the nut is overloaded. The nut b, Fig. 1, which is mounted in roller bearings in brackets p<1> of the machine slide has depressions f<4> in its periphery adapted to be engaged by a ball d carried by a rotatable sleeve c to hold the nut against rotation during feed. The ball d is maintained in engagement with the recesses in the nut by a roller h carried by a spring-pressed plunger e arranged in a part of the slide. Depression of the handle k fastened to the sleeve c, an overload, or the slide encountering a stop in either direction of motion, moves the ball out of its recess and allows the nut to slip, thereby stopping the feed. The feed may be modified or effected when the lead screw is stationary by rotating the nut by hand through gearing..

Filed: 1956-05-22
Abstract: 843,468. Programme-controlled electric copying machines. INDUCTOSYN Ltd. May 22, 1956 [Feb. 2, 1956], No: 15786/56. Class 40 (1). In a machine for producing a desired contour on a workpiece from a programme in the form of a series of punched cards giving digital information of consecutive values of slope, curvature, rate of change of curvature and feed rate, the digital values being converted into analogue values and combined via integrators, selsyn units and differential gears as described in Specification 807,220 to operate co-ordinate feed shafts 80, 82 (Fig. 9) whereby a cutting tool 1 and workpiece 7 are positioned to reproduce the desired contour, corresponding digital values of x and y are also supplied on punched cards, and the actual position of the cutter is compared with the required position and any error eliminated before the punched cards are advanced to the next set of digital values. All the digital input data, except the check values of x and y (designated x 0 , y 0 ), are combined to produce x and y values which are compared with, and correct, the actual x and y values representing the position of the tool 1 measured by coarse, medium and fine selsyn devices associated with the carriages 84<SP>1</SP>, 86<SP>1</SP>. This value of x is obtained on a shaft 122 (Fig. 7) from a differential gear DG3, one of whose inputs is the computed value of x on shaft 1220. The check value x 0  is fed from the punched card in coarse, medium and fine components to selsyn type devices R4, R5, 188 in opposition to the computed x value, the difference signal (x 0  - x) being fed to one winding of resolver R6, the signal in an output winding being modified as required mathematically in a series resolver R9 to produce the correction #x<SP>1</SP> which is the other input to the differential gear DG3, whereby the output on shaft 122 is the corrected value of x. The output from another winding of resolver R6 is used to energize relays A, B, the former opening contacts in the input circuits whereby changes in the input information are prevented from altering the computed value of x until the difference signal (x 0  - x) is too small to energize relay A, the second relay B then allowing the next entry on the punched cards to be read. Modification of the y signal on a shaft 124 is similarly corrected by a correction signal #<SP>1</SP>y to differential gears DG4. Specifications 801,516, 801,517, 807,218, 807,219 and 843,469 also are referred to.
