Abstract: 393,948. Holders for skeins of yarn &c. LYON, A., The Bushes, Paisley, Renfrewshire.. Dec. 14, 1931, No. 34563. [Class 120 (ii).] The arms of a holder for hanks &c. consist of spring metal strips 12, each mounted on a rotatable reel, the strips being flat in cross section when wound upon the reel but adopting naturally a cambered cross section when unwound therefrom ; the unwound strip is thus both straight and rigid. The strips are guided by apertures 13 in a casing 5 to a reel 6 on which they are wound. The reel 6 is mounted upon a bolt 7 which also passes through the casing and is provided with a nut 9 and rubber or other spring washer 10 to clamp the reel to the casing. In operation, a hank is placed around fingers 14 on the ends of the strips 12, the casing is held stationary, and the reel is rotated by lugs 11 to unwind the strips until the hank is properly held. The holder is then placed on a base having an upstanding pin adapted to enter an axial hole in the bolt 7 to permit the holder to rotate thereon. In a modification, each strip is wound on a separate reel and the reels are interconnected by gearing to wind or unwind the strips simultaneously.

Abstract: 1,017,543. Shift registers. STANDARD TELEPHONES & CABLES Ltd. Aug. 28, 1964 [Sept. 2, 1963], No. 34630/63. Heading G4C. [Also in Division H3] A shift register comprises a bi-stable circuit in which the transistors are switched from one state into the other by the residual charge in a series chain of two or more charge-storage diodes. Clock pulses are applied through diodes D2 and D2<SP>1</SP> to effect the switching which is inhibited by the presence of a gating input through Dl or D1<SP>1</SP> which effectively shortcircuits the charge-storage diodes. Any change in input information should occur only during the negative half-cycles of the clock pulses to avoid resetting by the input signals directly. The various circuit components can be formed in one single crystal of semi-conductor material.

Title: A device for regulating automatically the feeding of fabric or web into lapping-machines
IPC: D01G15/40
Filed: 1927-12-22
Abstract: 308,339. Ellis, R. E., (Rossweiner Maschinenfabrik Akt.-Ges.). Dec. 22, 1927. Registering webs.-In a cloth-rigging machine the parallel bars 4 between which the cloth passes on its way from the triangular board 3 to the delivery rolls 5, 6 are moved laterally by electric, pneumatic, or other means under the control of feelers' 10, 11 mounted on a carriage 7 movable on guides 19 in the direction of the plane of the doubled cloth, the arrangement being such that if only one feeler 10, 11 engages one edge of the cloth, the bars 4 are moved in a direction which will tend to bring the cloth edges level with each other, but if both feelers engage both edges, the carriage 7 will be moved away from the edges of the cloth, and vice versa. The carriage 7 is recessed centrally and fitted with a tongue 21 on each side of which the two edges 24, 25, Fig. 5, of the fabric pass. The feelers 10, 11 may make and break contact with the tongue or control other contacts 22, 23. An electric control system is shown diagrammatically in Fig. 7. The carriage 7 and the bars 4 are moved in one or the other direction by belt gearing 32 and reversing gearing 16, 15 according as the coils q or r, or m or n are energized. These coils are connected through relays 50 - - 53 with the contacts 22, 23 in the manner shown. Each of these relays has two contacts a, b and an operating coil s. When neither contact 22, 23 is closed nonaof the coils s will be excited and all four switch arms c will touch the contacts a, and the coils q will be energized, causing the carriage 7 to be moved away from the fabric. If both feelers 10, 11 do not engage the edges of the fabric, both contacts 22, 23 will be closed, the switch arms c will touch the contacts b, and the coil r will be energized and the carriage 7 moved towards the edge of the fabric. If only the contact 22 is closed the switches will occupy the positions shown and the coil n will be energized, causing the bars 4 to be moved in one direction. Movement in the other direction will be effected when the contact 23 only is closed. The circuit can be broken periodically by a switch 56 running in synchronism with a machine for piling the rigged fabric. Over-regulation may be prevented by arranging that the feelers 10, 11 are adjusted in the carriage 7, e.g. by screws 70, 71, Fig. 9, splined shafts 67, 68, ard gearing 65, 66 from the slide 17 carrying the bars 4, or the feelers can be fixed in the carriage 7 and the contacts with which they engage can be movable.

Title: Improved Tension Control System for D.C. Motor Reel Drive
IPC: B65H23/198
Filed: 1967-07-31
Abstract: 1,193,839. Controlling D.C. motors for strip winders. WESTINGSHOUSE ELECTRIC CORP. July, 31, 1967 [Aug. 10, 1966], No.35003/67. Heading G3R. Strip material 16 is maintained at a preset constant tension during winding or unwinding of a mandrel 14 by varying the armature current of the D.C. drive motor 12 so that it is directly proportional to the diameter of the coil on the mandrel and inversely proportional to the flux of the motor field 22. As shown the motor 12 is supplied by a D.C. generator 34 whose main field winding 38 is supplied from a thyristor exciter 40 having gating angle variation determined by a controller 62 supplied by an armature current signal from point 52 and by a signal from a current reference circuit 64. This latter circuit receives a signal representative of motor field flux from circuit point 54 and a signal representative of coil diameter from tachometers 20, 70 which respectively measure the speed of strip 16 and the angular speed of the mandrel 14. These signals are fed to conventional operational amplifiers, servodrives and potentiometers, Fig. 2 (not shown), which constitute the member 64 and which provide an output signal to the controller 62 equal to the ratio of coil diameter to the motor field flux. Controller 62 also receives signals from conventional circuits 66, 68 respectively providing inertia compensation during changes of strip speed and a limit on the output of controller 62 to prevent rated current being exceeded above a preset strip speed. The circuit 66 is supplied by the coil diameter/motor field flux signal from circuit 64 to provide linear acceleration and deceleration at constant strip tension and variable armature current. The motor field 22 is regulated to provide maximum torque per ampere value for the whole range of motor armature current operating values. To this end gating angle variation of the motor field thyristor exciter 30 is determined by a controller 44 supplied with a signal representative of field flux, from circuit point 58 and function generator 56, and with a signal from a conventional counter electromotive force controller 46 whose output calls for a field flux level to produce maximum allowable armature counter electromotive force over the range of operating speeds. In practice maximum field flux is produced up to the base motor speed and at higher speeds lower field flux levels are produced by the operation of the CEMF controller 46, which is supplied with signals representative of armature voltage and IR drop and with a set point signal 48 representative of the desired CEMF. The tension of the strip 16 may be preset to a desired value over a predetermined range of strip speeds by adjustment of a potentiometer in the current reference circuit 64. Instead of the generator 34, a thyristor rectifier may be used to supply the motor 12.
