Title: Improvements in devices for driving bodies revolving at high speeds, and in particular false twist spindles in crimping machines
IPC: D02G1/06
Filed: 1964-04-14
Abstract: In an arrangement for driving a false-twist spindle where the spindle is supported between two adjacent parallel circular members, and is driven by at least one of these members against which it is applied by the field of a permanent magnet, the magnet is in the form of a member co-axial with one of the circular members and rotating together therewith in Figs. 1 and 2, (not shown), false twist spindles 1 are supported by members 2, 3 each comprising discs 10, 11 rotating with a sleeve 9 fast on a shaft 6, one of the shafts being driven by a belt 4.  A magnet 5 having pole-pieces 7, 8 also rotates with each sleeve and collars 12, 13 on the spindles cooperate with the pole-pieces so that the magnetic flux flows through the collars and the spindles it to the axis 6, and prevents the spindle from moving axially.  The parts 9, 10, 11 are of aluminium, bronze or plastics material.  In another form, Fig. 3, (not shown), the spindle is supported by the pole-pieces 7, 8 which are of greater diameter than the flanges 10, 11 while the flanges 12, 13 are separated by a distance greater than that between the pole-pieces or are replaced by a single flange between the pole-pieces.  In Fig. 4, (not shown), the spindle is supported by a non-magnetic double-flange member 15 force-fitted on a non-magnetic ring 16 arranged between pole-pieces 7b, 8b on flanges 10b, 11b, nuts 17 holding the arrangement together. The pole-pieces may have areas of magnetic reluctance along their periphery.  An arrangement is described where fourteen false-twist spindles are supported by six circular members 2, 3.  The false twist spindle Figs. 7 and 8 (not shown), may have a sleeve-like extension with a slot 19 in which is fitted a diametral cross-member 20 with a notch of which the bottom is located along the axis of rotation of the spindle.

Title: Improvements in methods of cutting corundum rods
IPC: B28D5/02
Filed: 1945-06-25
Abstract: 594,047. Cutting corundum. LINDE AIR PRODUCTS CO. June 25, 1945, No. 16112. Convention date, July 15, 1944. Addition to 581,619, [Group VII]. [Class 124] In a method of producing discs from synthetic unicrystalline corundum rods as described in the parent Specification, a rod is selected wherein the angle between the optic axis and the longitudinal axis is between 30 and 80 degrees and disposed in such a position with respect to a tool, e.g. a saw, that of the total force exerted by the tool, that component which is parallel to the optic axis is at the minimum value, a disc being then cut from the rod. The component parallel to the optic axis should not exceed 40 per cent of the total force applied. As shown, a corundum rod 11 of <3>/16 inch diameter has a plane 13 passing through the optic axis and the longitudinal axis indicated by a line 15 and a rotary saw blade 19 is arranged to cut vertically downwards through it, the components of the force exerted by the saw being vertically downwards, transversely of the rod and parallel with the length of the rod. The plane 13 may vary through an angle b relative to the normal to the plane 13 in the position shown, b being 0-30 degrees. The line 15 indicating the optic axis may be marked along the whole length of the rod and the direction of the optic axis indicated by a band 17, the position and direction of the optic axis being found by X-rays or a polarimeter. Before sawing, the rod may be mounted on a support as indicated in Fig. 4 (not shown). If sawing takes place along a non-diametrical chord of the saw, the rod should be maintained in a position such that the normal to the plane 13 forms an angle between 0 and 30 degrees with the constantly changing direction of progression of the saw through the rod, as indicated in Fig. 7 (not shown). The Specification as open to inspection under Sect. 91 comprises also the rotation of the rod during sawing. This subject-matter does not appear in the Specification as accepted.

Abstract: 416,807. Slicing-machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij Van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland.) Sept. 21, 1933, No. 16134. [Class 28 (ii).] In a slicing-machine, the substance is guided during its feed movements between a rigid upstanding guide wall 6, remote from the operator, and a guide wing 8, adjacent to the operator, the wing being carried by, and adjustable along, a guide bar 9 at the side of the carriage remote from the knife 1. A combined pusher and clamp 3 is slidable along a bar 7 carried by a bracket 7<a> against which the wall 6 abuts. The wing 8 is pivotally connected to a slide 10 on the bar 9 and is operated by the handle 14. A finger 17 on the pivot shaft is positioned between stops 11, 12 on the slide 10 and a spring 13 tends to move the wing towards the wall 6. The force of the spring also causes the slide 10 to bind on the guide and to lock it thereon. Locking may be effected positively by the screw 15. Alternatively a clutch ring or pawl and rack lock may be used.

Filed: 1964-04-20
Abstract: 1,072,752. Inductors. S. T. DUPONT. April 20, 1964 [April 30, 1963], No. 16374/64. Heading E1T. An electromagnetic push switch assembly comprises a coil 1 (Fig. 1) connected as one leg of a bridge circuit (Fig. 2, not shown) and having the same resistance value as each of three resistors which constitute respectively the other arms, a magnetcic core 5 movable within the coil and biased by a spring 10 to a relatively retracted position in which the bridge is balanced. Pressure on an extension of the core, which serves as a push button, inserts the core further into the coil, increasing its effective resistance and unbalancing the bridge. The unbalance voltage is amplified in a transistor (33), Fig. 2 (not shown), and energizes and actuates a relay switch (34) provided it has sufficient magnitude. A potentiometer (35) is provided to adjust the threshold voltage value.

Title: Improvements relating to circuits for translating electrical signals
Inventor: ROSSER WILLIAM JAMES
IPC: H04N5/18
Filed: 1952-07-01
Abstract: 733,360. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 1, 1953 [July 1, 1952], No. 16503/52. Class 40 (3). Relates to a levelling circuit as shown in Fig. 1 in which in addition to the normal clamp circuit 4-7 there is provided a conventional leak resistor 21 together with switch means 17, 18 and 23 arranged in one position to open circuit the leak resistor whereby the levelling circuit may operate normally and in the other position to connect the leak resistor in circuit and simultaneously to bias the clamp circuit in operation whereby the circuit may translate sinusoidal alternating signals for test purposes. Where valve 2 is of a high-power type necessitating a low value for resistor 21, distortion of the signals translated during normal operation occurs due to the discharging of condenser 3 into stray capacity 27 associated with the wiring to switch 23. In accordance with the invention, this defect is mitigated by applying feedback to the leakage resistor in such manner as to increase its effective value. In one manner of carrying this out, Fig. 2, valve 2 is arranged as a cathodefollower and a connection is taken to the remote end of resistor 21 through a capacitor 30 from the cathode load 29. The capacity of capacitor 30 is chosen to be at least five times that of the stray capacity 27, and if this imposes too great a load on the cathode circuit of valve 2, an additional resistor 21 is introduced of value large compared with the reciprocal slope of valve 2. In a modification, Fig. 3 (not shown), valve 2 is arranged as an amplifier with an anode load but including also a cathode resistor to provide feedback to the leak resistor 21. Specification 512,109 is referred to.

Abstract: 734,073. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 5, 1950 [June 22, 1949], No. 16588/49. Divided out of 731,341, Class 106 (1). In an electronic digital computer in which operations are controlled by successively selected instruction words stored in the computer, means for altering an instruction word under the control of an applied modifying word are provided in the path by which each instruction word is read out from its normal storage location and fed to a control system, whereby the instruction word effective in the control system may be altered from that which is supplied from the store. The computer described is related to the modification described in Specification 734,074 of the complete machine described in Specification 731,341 employing C.R.T. stores as described in Specifications 645,691, 657,591 and 705,474. As shown, instruction-modifying words are stored in a special store BS of which the C.R.T. screen, as described, has two 40-digit lines B 1 , B o  each holding two words (the words on B o  being normally zero). The first or " C " digit of each control instruction stored in control unit CL determines which half of a line in the main store shall be read out to form the present instruction as described in Specification 734,074, and similarly selects one half of the line B o  or B  1 , the line itself being selected by the first or " b " digit of the present instruction through Y-shift generator 85 (Fig. 14, not shown). The selected instruction-modifying word is passed through gate 84 to the adder 30 (or a subtractor) of the control unit at the same time as the present instruction is passed thereto from gate OTG. Words may be entered into the store BS through gates OTG and 83 and a one-digit-shift or delay circuit 86. Reference is made to other forms of store, e.g. electromagnetic arrangements or supersonic delay lines.

Filed: 1919-07-03
Abstract: 153,349. Bates, A., and British United Machinery Co., (United Shoe Machinery Corporation). July 3, 1919. Lasting and pulling-over.-In an upper-pulling machine of the kind described in Specifications 14453/97, 7005/00, 9793/08, and 11222/08, baving gripper mechanism and an actuator for moving the gripper bar axially. to stretch the upper, mechanism is provided to change the connexion cf the bar and actuator automatically, so that the bar is moved axially. while the upper is gripped, at one time yieldingly and at another time positively. As shown in Fig. 1, the cam-operated slide 6 first moves the gripper lever 4 yieldingly through the spring 12. When the slide 6 has descended sufficiently to free a member 14 pivoted thereto from a stationary cam-surface 24, a tooth 16 on the member 14 engages one of several teeth 20 and positively connects the slide 6 and lever 4 for the remainder of the pull. Similar mechanism in which the action of the teeth is reversed may be added to that described in Specification 18523/11, so that the periodic relaxation of the pull of the grippers may be positive. Fig. 2 shows mechanism for giving a final positive pull to the grippers in the machine described in Specification 1866/12. wherein a hand-lever 40 operating a gear segment 38 co-operating with a segment 36. on a rock-shaft 34 is employed to vary the pull on the grippers. A cam 94 is provided on the cam shaft 2 engaging a roll on a push-rod 80 moving clutch members 74, 76 separated by a spring to the left. The clutch member 76 has a gear segment 64 meshing with a segment 62 on a rockshaft 58 having a pinion gearing with a rack on the slide provided for giving an overdraw to the grippers. Movement of the push-rod 80 to the left moves the clutch members 74, 76 similarly until a barrel 72 on the first contacts with an adjustable stop 92. Further movement of the rod 80 closes the clutch members and, the segment 64 being at this time oscillated, turns the barrel 72 and an arm keyed thereto and linked to the rock shaft 34. The pull on the grippers is maintained .till the rod 80 returns by 'a fixed pawl engaging teeth on the barrel 72 when this is pressed to the left, the portion of the barrel with which the pawl contacts in the normal position of the parts being plain. i-jpecifications 18621/11 and 16398/15 are also referred to, and the subjectmatter of Specification 153,353 is disclaimed.

Title: Improvements in or relating to machines for moulding counters for boots or shoes
IPC: A43D8/04
Filed: 1936-06-17
Abstract: 481,867. Shoe stiffeners. BRITISH UNITED SHOE MACHINERY CO., Ltd., BENNION, L. H., and SMART, W. A. June 17, 1936, No. 16805. [Class 17 (i)] The counter-moulding machine described in Specification 268,032, [Class 17 (i)], is provided with improved mechanism for stopping the machine at the end of the cycle with the moulds in position for the insertion of a fresh counterblank. The mechanism also provides for automatic starting of the machine, but is provided with means for preventing this starting except when the picker arm described in the prior Specification is in appropriate position, and means whereby the operator may stop the machine at any time. The machine is constructed as described in the prior Specification except that the mechanism designed to cause de-clutching of the driving shaft after two wiping movements of the flange former is substituted by the following mechanism. A pulley 504, loose on a shaft 500, is driven at a constant speed by a belt 502 and carries a pinion gearing with a spur wheel 508 itself rotating with a pinion 512 gearing with a spurwheel 514 fast on the shaft 500, this shaft being thus constantly driven at about 14 revolutions per minute. The shaft 500 carries two cams actuating a roll 526 and a lever 572 to operate a rock-shaft 113 described in the prior Specification as secured to a fork 115 actuating a clutch sliding on a driving shaft 103 to start and stop the machine. The rockshaft has an arm 544 co-operating with an arm 542 of a bell-crank lever pivoted to a link 518 the free end of which is carried by a link 520 carrying the roll 526. A normally horizontal arm 538 of the bell-crank lever is urged against a stop 540 on the link 518, and is depressed to swing the arm 542 anticlockwise when the machine is to be stopped. The flange-forming lever 189 described in the prior Specification carries a pin engaging a slot 550 rising and falling with a link 560 urged upwardly by a spring 584 and engaging a hole in a slide 562 reciprocated by the lever 572. At the beginning of a cycle, as the roll 524 descends, the arm 542 rocks the shaft 113 to engage the clutch. At the end of the first reciprocation of the flange former, the link 560 descends, but does not free the clutch because the slide 562 is in its left-hand position. At the end of the second reciprocation, however, the slide has been moved to the right, and the lower end of the link 560 frees the clutch. Unless the picker arm, described in the prior Specification, is in any but its rest position, the machine is prevented starting. The bevel 261 actuating the picker rotates with a cam having a single recess receiving a roll 588 connected to a link 594 actuating a plunger 600 co-operating with the arm 538, to prevent clutch engagement unless the roll 588 is in its recess. The link 594 also engages a lever 604 connected to a treadle rod 606 for stopping the machine at any desired point.
