Title: Method and apparatus for winding yarn on a bobbin
IPC: B65H59/38
Filed: 1973-05-15
Abstract: 1434123 Yarn winding apparatus TEIJIN Ltd 15 May 1973 [15 May 1972 (2) 27 May 1972 6 June 1972 8 June 1972] 23038/73 Headings DID and D1J A yarn traversing roller 5 is traversed substantially parallel to the axis of an upright bobbin 6 at a speed slow enough to lay the yarn turns in a side-by-side relationship so that following laps are adjacent to, but do not overlap earlier laps of the same traverse, the guide roller 5 lying in a vertical plane that, at least at the start of the winding operation, contains the axis of the bobbin 6, the yarn leaving the guide roller being in a plane that is substantially 90‹ to the axis of the bobbin. A dancer roller 4 moves in response to changes in yarn tension, such movement causing a tension detector to activate a control circuit 13 for a D.C. motor 9 rotating the bobbin 6, the control being such that the tension in the yarn remains substantially constant. Switch means (not shown) can be operated to cut-out the detector 12 and, instead, temporarily cause the bobbin support 6 to rotate at a peripheral speed slightly higher than the normal speed of the yarn 1, this alternative speed being used at a change-over stage when the winding of yarn onto a fresh bobbin is to commence. Doffing and donning. When the package is fully wound, an aspirator 23 at the position shown in solid line in Fig. 1 is moved up by an air cylinder and stopped at position 23' shown by broken lines. When the travelling yarn contacts a cutter 22 on the aspirator 23, the yarn is cut. The tail end of the package is wound up and the other end is pulled into the aspirator 23. The aspirator 23 then moves down. The package is removed from the bobbin support and an empty bobbin is placed thereon by an operator. The aforesaid switch is then operated to cause the peripheral speed of the bobbin to be slightly in excess of 'the normal delivery speed of the yarn. A pneumatically operated rack 39 is then moved downwardly to cause a pinion 38 to swing an arm 31 and roller 30 clockwise in a manner moving the yarn out of the aspirator 23 and onto a hook 41 on the bobbin 6. A fresh winding is then commenced and the aforesaid switch is operated to bring the dancer roller 4 back into operation.

Title: Metal strip feed device
Inventor: SCHLUETER WALTER
IPC: F15B11/048
Filed: 1969-05-06
Abstract: 1,268,452. Metal strip feeds. WILHELMSBURGER MASCHINENFABRIK HINRICHS & SOHN. 6 May, 1969 [31 May, 1968], No. 23101/69. Heading B3W. In a strip metal feed device comprising an hydraulically-operated reciprocating gripper 10, during the final portion of at least the feed stroke the gripper is caused to decelerate by engagement of a cam rail 14 mounted on the gripper with a member, such as a spring-loaded roller 15, which causes a regulator valve 38 progressively to shut off the line 31 through which hydraulic fluid is being exhausted from the actuating cylinder 12 to return line 30. A similar cam rail and a roller 15<SP>1</SP> may provide for deceleration during the final portion of the return stroke also. The cam rails may be angularly adjustable or interchangeable with rails of differing configuration to vary the rate of deceleration and the length of the stroke during which it takes place. As shown, Fig. 3, hydraulic fluid is pumped to either end of the hydraulic piston-cylinder unit 12 via a slide control valve 21, non-return valves 36, 36<SP>1</SP> and regulator valves 38, 38<SP>1</SP>. To move the gripper in the feed direction 9<SP>1</SP> the slide 20 is moved to the left so that liquid is pumped through the line 32 to cylinder 12 and exhausted through regulator valve 38, a line by-passing the non-return valve 36 and a line 31 to the sump 18. Towards the end of the piston stroke the roller 15 runs up cam surface 54 and closes valve 38 which progressively shuts off the line 31 thus slowing down the grippers until at the end of the piston stroke the line is closed. The slide 20 is moved to the right for the return stroke during which roller 15<SP>1</SP> acts in the same manner as roller 15. A stationary gripper 2 is provided.

Title: Improvements in or relating to rotary cutters in or for use in machines suitable foroperating on shoes or parts thereof
Inventor: JAMES CYRIL HARRY
IPC: A43D29/00
Filed: 1961-06-28
Abstract: 1,027,991. Roughening shoe soles &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. Aug. 27, 1962 [June 28, 1961; Aug. 29, 1961], Nos. 23330/61 and 31012/61. Heading B4B. [Also in Division A3] A rotary cutter in or for a machine for roughening shoe soles &c. comprises a plurality of cutter teeth extending from a hub member, the cutter teeth being in two sets arranged alternately one from each set around a peripheral portion of the hub member, each cutter tooth of a first one of the sets having a cutting edge for making an undercut in the surface of a workpiece when operated upon by the cutter and each tooth of the other set having a cutting edge for making a severing cut through the undercut formed in the workpiece by the preceding tooth of the first set. As shown in Fig. 1, the cutter comprises an inverted cup-shaped hub portion having a rim portion 3 formed with recesses 2 in each of which a flat 12 on the stem portion 10 of a cuttertooth is clamped by means of a wedge 4 and set-screw 5. Each of the undercutting teeth, Figs. 2 to 4, has a sintered carbide tip 14 and faces 16, 18 which intersect to provide a cutting edge 20 which when the cutter is in the machine lies at only a slight angle to the work. The intersection of faces 22, 16 provides an edge which slopes inwardly and rearwardly in the direction of cutter rotation. As the cutter rotates, the cutting edge 20 cuts into the sole blank material and the undercut portion of the blank is then prised upwardly, as the tooth travels across the material, by the action of the face 16 and/or the edge between the faces 16, 22. Each severing tooth, Figs. 5 to 7, has a sintered carbide tip 30 and has a face 32 and an oblique face 34 which intersect to produce a cutting edge 36 extending upwardly and rearwardly in the direction of cutter rotation. The teeth are such that when mounted in the cutter rim, pointed tips 26, Fig. 4, and 38, Fig. 7, of the two types of teeth lie substantially at the same distance from the axis of the cutter. Hence the servering teeth act to sever those portions of the material of the blank which have been undercut and prised upwardly of the undercutting teeth. The oblique faces 34 of the severing teeth tend to deflect the chips of material cut off from the blanks towards the centre of the cutter where they are removed by a dust extraction unit. A modified form of undercutting tooth and a modified form of severing tooth for use in conjunction therewith are described.

Patent GB-1106547-A (GB)
Title: Method and apparatus for the electrolytic de-silvering of photographic processing liquids
IPC: C25C1/20
Filed: 1965-06-02
Abstract: Silver is recovered from a photographic processing bath by continuously flowing the liquid to a plating out cell and back again. Electric impulses are generated, proportional in number to the throughput of photographic material to the bath, and are stored in a data storage device. Feeding of data to the storage device switches on current to the plating out cell at a current density optimum for the plating out process.  The passage of plating current causes exhaustion of the data storage device and continues until the store is empty, passage of current commencing on or after generation of the initial impulse and continuing beyond the time during which photographic material has been treated and the impulses are generated.  The storage device may be a rotating wheel Figs. 2 and 3 (not shown) which co-operates with a fixed electrical contact to start the plating process when impulses are received.  Input of data, from the generated impulses, is recorded by rotation of the wheel in one direction from one side of a differential gear, and exhaustion of data, proportional to passage of current through the plating out bath, is caused by rotation in the other direction from the other side of the differential. Data may be stored as a content of liquid in a tank Fig. 5 (not shown), input and output of data being represented by inflow and outflow of liquid. Data may be stored as a number of steel balls in a container Fig. 6 (not shown), inflow of balls being proportional to the number of impulses received, outflow of balls controlling the current to the plating out cell.
