Title: Improvements in or relating to Automatic Control Devices for Gear Teeth Grinding Machines
IPC: B24B47/04
Filed: 1967-12-04
Abstract: 1,174,680. Grinding. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. 4 Dec., 1967 [17 Dec., 1966], No. 54985/67. Heading B3D. A control device in a machine for grinding gears and splined shafts comprises mechanical path measurement means for the selective movement of a grinding spindle carrier 1 into a grinding position corresponding to the respective grinding allowance and into a position for dressing the grinding wheel. As shown, pins 14a-14d of different lengths are inserted into holes in a programme disc 13 to selectively actuate switches 15a-15d when driven by a feed motor 11; each grinding allowance is determined by the spacing of pins 14a and each dressing operation is determined by a pin 14b. Before grinding, the feed motor 11 simultaneously rotates the programme disc 13 clockwise and slides a limit nut 9 to the left within a piston 8, the switch 15c being actuated and the piston moved to the left by hydraulic pressure; a feed wedge 6 attached to the piston causes the grinding spindle carrier 1 to be raised. After a predetermined number of strokes of the horizontally reciprocating work-table, a counting mechanism switches on the feed motor 11 to move the feed wedge to the right by an amount corresponding to the first grinding allowance and to initiate the selected work operations. After the required number of teeth have been ground as set by the counting mechanism, the work operation is repeated on the same teeth at the next grinding allowance. If a pin 14b encounters a switch 15b then a wheel dressing operation is initiated, the piston 8 being moved by hydraulic pressure to the right over the nut 9 to lower the grinding spindle carrier 1. A motor 17 operating through a clutch 19 feeds the amount to be dressed. After the dressing operation, the piston is returned by a signal from the dressing apparatus to re-set the grinding spindle carrier to the position occupied before dressing less the feed amount which the nut 9 has introduced in the meantime. After sparking out, the work-table is stopped and the grinding spindle carrier 1 and the programme disc 13 are automatically re-set by the switch 15d to the position selected by the pin 14c. A hand wheel 18 is used to adjust the carrier 1 for a different workpiece or grinding wheel. In an alternative arrangement of the programme disc, the pins are of equal length and are disposed radially on a thicker disc.

Filed: 1965-12-29
Abstract: 1,158,790. Measuring liquid density electrically. SOLARTRON ELECTRONIC GROUP Ltd. Dec. 19, 1966 [Dec. 29, 1965], No.55112/65. Heading G1N. In a liquid density meter of the kind in which the natural resonant frequency of a container filled with the liquid is measured, the container consists of two identical, parallel, tubes of resilient material which are caused to oscillate in anti-phase. In one embodiment, the tubes 11, 12 Fig. 1 are made of an iron-nickel-chromium alloy, joined together by webs 13, 14 which are supported by resilient mountings Fig.3 (not shown). The tubes 11, 12 are connected by rubber tubes 57 (or stainless steel bellows) to Y-pieces 53, 54 through which the liquid under test flows. Each Y-piece houses a platinum resistance thermometer 41. The tubes are caused to oscillate by a drive coil 22 energized from an amplifier, Fig. 4 (not shown) having positive feedback from a pair of pick-up coils 23, 24. A D.C. winding on the drive coil assembly sets up a steady magnetic field through the tubes and through magnetic shunts 25, 26. D.C. bias windings are also provided on the pick-up coils. The frequency of the oscillatory current in the A.C. windings is measured by conventional frequency meter, or by a pulse counting circuit. In a second embodiment, Fig. 9 (not shown), the two tubes are connected at one end to form a U-tube. In either embodiment, the tubes may be internally coated with polytetrafluoroethylene. In a third embodiment, Fig. 5, the two tubes 111, 112 are made of non-magnetic stainless steel through which current from an amplifier 126 is passed so that they oscillate in a magnetic field set up by a pair of permanent magnets 113, 114. Oscillation is maintained by feedback from strain gauges 121 on the tubes. The tubes may have flats on the outside walls, Fig. 6 (not shown) or may be of oval or rectangular crosssection, Figs 7 and 8 (not shown).

Abstract: 1,246,737. Re-arranging and turning articles on an endless conveyer. AVERY PRODUCTS CORP. 13 Nov., 1969 [5 Dec., 1968], No. 55673/69. Heading B8A. Apparatus for arranging in single file and uniform orientation on a moving surface a plurality of similar flat workpieces 10, 10a that  are being carried by the surface in double file  with the orientation of the workpieces in each file being uniform within the file but the orientation of the workpieces 10 in one file being angularly removed from the orientation of the workpieces 10a in the other file by a given angular distance, including a translating carriage 25 in which is mounted a down-up vacuum pick-up head 51, 51, for oscillatory rotation through the angular distance, means 28 for translating the carriage between a pick-up station (R.H. position on belt 13, Fig. 2) and an unloading station (L.H. position, Fig. 2), a rack 60, 60 adjacent the path of translation of the carriage for rotating the vacuum head 51, 51 through the angular distance as the head translates, means for momentarily depressing the vacuum pick-up head at the loading station to engage the package, means to apply vacuum to the pick-up head when the momentary depressing means is actuated, and means to release the vacuum and reverse the carriage translating means when the translating head reaches the unloading station. Operation.-A package 10a, by tripping a limit switch 60 energizes a timing relay (63) (Fig. 6, not shown). This results in energization of a solenoid (68), thereby reversing fluid pressure valve (72) (Fig. 5, not shown), thereby applying pressure to a cylinder 57. The ram 58 of the latter is pushed down, so as to engage and push down a spindle 36 which carries the pick-up heads 51, 51. Valves (90) and (77) are also operated as the result of tripping the switch 60. The former causes vacuum to be applied from a source (75) to the heads 51, 51. The latter causes fluid pressure to be applied to a cylinder 28 which moves the carriage 25 on guide rods 23, 24. A gear 45 fixed to the head 51, 51 is thereby rotated by engagement with a rack 60. The package 10a is thus rotated through 180 degrees into the same orientation as the packages 10. When the package 10a is in position above the axis of the row of packages 10a, probe 80 on the carriage, operates a switch 71. This reverses the valve (90) so as to exhaust the suction at the gripper 51, 51, and the package is dropped. The circuitry is such as to cause the carriage to return and the cycle recommences.

Title: Stranding of Elongate Elements
IPC: H01B13/02
Filed: 1967-12-15
Abstract: 1,188,038. Cables. SIEMENS A.G. 15 Dec., 1967 [16 Dec., 1966; 24 May, 1967; 30 June, 1967], No. 57219/67. Heading H1A. In the manufacture of stranded communications cables with periodic reversal of twist, the elements to be stranded are drawn through an intermediate store in which the length of the elements stored is continuously increased or decreased with periodic reversal, and stranding is effected by a rotation always in the same direction about the stranding axis. The rotation may be that of the intermediate store about the stranding axis. Alternatively a stranding frame which carries the elements rotates about the stranding axis and the non- rotating intermediate store, such a frame being described in Specification 1,165,411. As shown in Fig. 1, the store 3 of varying content comprises a pair of rollers movable towards and away from each other. One roller may be fixed while the shaft of the other is mounted on a pair of shafts and moves between a pair of stops, by means of a system of gears operated by rotation of store 3 (Fig. 4, not shown). The constant velocity rotation of store 3 imparts a twist to wires at stranding nipple 1. Further since the stranded wires 4 leave the store with a constant velocity which differs from the velocity at which the wires are fed to the store, the latter velocity varying with the movement of the rollers, they are not completely untwisted, the residual twist being reversed when the relative motion of the rollers changes direction. The arrangement illustrated in Fig. 2 is such that the velocity of feeding to the stranding assembly may be the same as that of drawing-off. Wires 4 are fed to a first variable content store 5 then via spreader 6 and stranding nipple 2 to similar store 3. The relative motion of the rollers in the two stores is equal but opposite, and the relative angular velocity of the two stores is different from zero, e.g. as shown, store 5 does not rotate. Several of such stranding devices operated in parallel may supply stranded wires to a further stranding device which may or may not be one imparting reversed twist (Fig. 8, not shown). The first stranding devices may be so positioned that the locations of twist reversals are staggered in the product of the second stranding operation. Further, single cores may be supplied to a number of the devices in parallel for pretwisting prior to reversed-twist stranding (Fig. 9, not shown). Preferably the devices working in parallel and the single device for the next stranding stage are mounted together on a rigid frame (Fig. 10, not shown). The opposite variation in distance apart of the rollers in the two stranding stages may be achieved by the reciprocating motion of a cage mounted between the stranding devices.

Abstract: 1,173,750. Skein removing apparatus. CROON & LUCKE MASCHINENFABRIK G.m.b.H, 21 Dec., 1966 [28 July, 1966], No. 57263/66. Headings D1F and D1J. A skein removing apparatus 40, having rods 41 insertable within skeins wound on winding baskets 7 of adjustable winding diameter of a skein winding frame, is brought into operative connection with the winding frame when the skeins are fully wound and the driving motor for the baskets has been interrupted. The apparatus 40 causes actuation of a first switch 36 to provide a second interruption of the circuit of the driving motor circuit for safety reasons and actuation of a second switch 45 which effects through a reversible motor reduction of the winding basket diameter to a predetermined minimum value so causing transfer of the skeins to the rods 41. Subsequent withdrawal of apparatus 40 automatically releases the two switches causing first operation of the reversible motor to adjust the winding baskets to their maximum winding diameters and secondly to cause switching on of the winding motor. The baskets each comprise spurs 7 connected by adjustable struts 3, 4, 5 to a central spindle 8, and the rods 41 are at such a height that they enter the winding baskets a little below and inside the outside edge of the spars forming the basket at the topmost position (Fig. 2a). A pivotable frame 30 mounted on the winding frame normally surrounds and protects the baskets during winding but is caused to upwardly pivot due to it riding along sloping part 40b-40c of apparatus 40 when it is inserted. The upward pivot of frame 30 causes actuation of the first switch. The second switch is actuated by the middle web of a T-shaged base of the skein removing apparatus which enters free end first into a guide 37 on the winding frame. A pair of rods 41 are provided for association with each winding basket. The gearing and electrical circuitry of the winding frame is illustrated in Figure 5, not shown. The winding frames are equipped with counting mechanism for preselection of the turns of yarn for each completed skein and. by means of which the frame is switched off automatically when the skeins have reached the desired number of turns.
