Title: Improvements in or relating to haul-off devices
Inventor: BURR HARVEY
IPC: B21C47/14
Filed: 1959-02-24
Abstract: 868,152. Winding and coiling wire. BRITISH INSULATED CALLENDER'S CABLES Ltd. Feb. 24, 1960 [Feb. 24; 1959; Dec. 18, 1959], Nos. 6348/59 and 43202/59. Class 83 (4). Apparatus for coiling wire comprises a stationary ring wall whose internal surface forms an endless track, a pulley which under operating conditions is driven along the track, and means for leading wire substantially axially towards the centre of the track and then towards and on to that part of the pulley that is approaching the track, whereby as the pulley rolls along its track it momentarily traps between it and the track successive elemental lengths of wire and draws the wire through the device, at the same time imparting a curvature to it. Wire passes around pulleys 3, 4, the pulley 3 being movable in dependence on the tension in the wire to control the speed of the wire coiling means, down a rotary hollow shaft 10, carrying a flyer 12 at its lower end, around a pulley 19 on the flyer 12, then between a rubber-rimmed roller 15 and a stationary cylindrical track 9. The wire is thereby curved and then passes through a guide tube 21 on the flyer 12. This tube 21 is curved in the same sense as the pulley surface, adjacent thereto, then is curved in the reverse sense and the remainder curves downwardly. The wire then falls in suitable coils into a container 6, rotated slowly about an axis, slightly displaced from the axis of the flyer 12, by a table 41 driven through clutch means 43 from the drive 30 to the flyer 12. A motor 27 drives the means 30 through an infinitely variable gear 28 controlled by speed control 40 actuated by chains 39, 36 and 34 connected to the movable pulleys 3 so that variation in tension of the wire passing over the pulleys 3, 4 varies the speed of the machine in a way to maintain the tension constant. While containers 6 are being changed, wire being delivered from the guide tube 21 is supported temporarily on a platform 44 moved laterally on guides 49 to a position beneath the coiler. A stop 51 pivoted to the machine frame serves, when in a vertical position to sweep accumulated coils into the container 6 as the platform 44 is withdrawn, the stop 51 being held horizontal during filling of the container 6 by pins on the platform 44. Alternatively, Fig. 7, the coils may be temporarily supported by fingers 61 swung to a position under the coiler by a chain 66 and lever 67. The track 9 may be of elliptical form or conical or conoidal in which latter cases the pulley 15 may be suitably tapered. The axis of the track may be horizontal.

Title: Warp sleying apparatus
Inventor: COOK WILLIAM WALTER
IPC: D03J1/14
Filed: 1960-02-24
Abstract: 944,701. Reed threading machines. WOOL INDUSTRIES RESEARCH ASSOCIATION. Feb. 23, 1961 [Feb. 24, 1960], No. 6469/60. Heading D1M. The invention concerns a motorised carriage with a photo-electric device for threading warps through reeds. The reed baulks 14 are located between spring-loaded rollers 13 and flexible rollers 4 driven from a motor-reduction gear unit 7. Steadying rollers and adjustment screws 16 are provided. A photo-electric device 19,22 is provided at either end of the machine. Upon starting and with a threading blade 26 between the wires 24 of the reed, the operator loops a yarn over the blade 26 and pulls the blade to the position 26a to pivot a lever 33 which operates a switch to energize a solenoid 29. The movement of the solenoid loads a spring acting on the blade 26 so that when the operator releases the yarn the blade 26 takes it through and clear of the reed to the position 26b, and in so doing the blade 26 pivots a lever 27 to start the motor 7 to drive the rollers 4. As the carriage moves, the reed wire 24 obstructs the light from the bulb 22 and, after further movement, the cell 19 again receives light and through a control circuit (Fig. 6, not shown) de-energizes the solenoid 29 to release the spring holding the blade 26 which returns to its original position and in so doing switches off the motor 7. The cycle is then repeated. The carriage is traversible in either direction.

Title: Improvements in or relating to key holders
IPC: A45C11/32
Filed: 1936-03-07
Abstract: 461,719. Keyholders. PETRIE, W. K. March 7, 1936, No. 6960. [Class 44] A holder for keys of the revolving barrel pintumbler lock type comprises a pair of guardplates 1 held together in spaced relationship by countersunk screws 3 passing through apertures near the ends of one plate and entering internally-threaded sleeves upstanding from the other plate. The keys are pivotally mounted on the screws and sleeves which allow adjustment of the distance between the plates according to the number of superposed keys to be held. The keys 4, 5 fold into place side-by-side between the guard plates which are cut away at 6 to expose portions 7 of the keys. Pressure on the portions 7 of one set of keys moves the other set outwards until their free ends are accessible to allow further movement of a selected key into fully exposed position for use. Springs such as 8 may be provided to hold the keys normally between the guard plates. In a modification, the guard plates are spaced apart by upstanding lugs 10, on a third plate 9, Fig. 4, positioned between the guard plates, which have a contour corresponding to that of spacing plate 9.. In this case variation of distance between the guard-plates is effected by selection of a plate 9 having lugs 10 of appropriate height. Lugs 10 also serve as stops to ensure that the sets of keys mounted on the two pivots can only be moved into and out of the holder on opposite sides thereof. Plates 1 may have marks to allow identification of the keys by feel.
Patent GB-360441-A (GB)
Title: Improvements in or relating to the preparation of photomechanical printing surfaces
IPC: G03F3/10
Filed: 1930-05-03
Abstract: 360,441. Colour printing. HAUSLEITER, F. H., Guntherstrasse, Munich, Germany. May 3, 1930, No. 7002. [Class 98 (ii).] To obtain reproduction with more correct colour values particularly in relation to the black and white gradation, an auxiliary negative of the black and white gradation, (e.g. taken on a panchromatic plate with a balancing filter), is used as a mask at some photographic stage in the production of each colour printing surface to suppress the black and white gradation to a greater or lesser extent. The auxiliary negative in some processes may be of greater density and used as a mask to produce colour component negatives in which the black and white gradation is suppressed to a very considerable degree, and these '' colour supplements " used in conjunction with ordinarily produced but imperfect colour components to enhance or adjust the colour rendering of the colour black at some stage of its production. Auxiliary negatives may be used for each component colour, and may be specially taken to adjust any dominant colour value. Four typical processes are described: (a) An auxiliary negative of the black and white gradation may be taken and used as a mask in taking colour selection negatives through colour filters and so as to mask the black and white gradation to a limited degree. The exposure will necessarily be longer than normal and the colour selection negatives so produced will be more perfect for practical use in making the colour printing blocks. (b) Colour selection negatives are made in the ordinary way through colour filters, and these negatives combined with " colour supplements " in producing the component positives or screen diapositives. (c) A modification, particularly applicable for intaglio printing, consists in combining normally taken colour selection diapositives with diapositives of " colour supplements" for reproduction on pigment paper or direct on to the metal surface to be subsequently etched. The process screen can be used at any stage. (d) Alternatively, when producing screen diapositives from normal colour selection negatives, a supplementary printing may be given from the corresponding " colour supplements," or the superimposed image produced by resensitizing re-exposure.
