Title: Improvements in or relating to pressure sensitive devices
Inventor: DRESSLER ROBERT LEONARD
IPC: B65G67/00
Filed: 1964-03-11
Abstract: 1,059,935. Level detector for material. GENERAL ELECTRIC CO. Ltd. April 23, 1965 [March 11, 1964], No. 10277/64. Headings B8E and B8S. A pressure-sensitive device 11 carried by a boom 4 is used to detect the level of material in a container. The device consists of a mounting 13 attached to the boom and a flexiblywalled hollow protuberance 12 projecting from the mounting. The protuberance may be a flexible hemisphere as shown, or a bellows. When the protuberance contacts the material whose level is to be detected, the flexible walls are distorted and a signal is given. The mounting and the inside of the protuberance may be metallic or metal-coated to provide electrodes 14, 15. In this case the signal is electric, e.g. the device operating as a switch when the two electrodes touch as shown, or the variable capacitance between the electrodes being used to unbalance a bridge circuit controlling a relay. Alternatively, the signal may be provided by fluid pressure generated by flexure of the protuberance, e.g. to operate a pneumatic relay. The device may be used to control the loading of a vehicle 7 (Fig. 1, not shown), from a hopper (6) by means of a conveyer running along the boom 4, which in this application is pivoted (at 8) to the hopper. The signals from the level.sensing device operate the motor control of a hoist (9) which controls the boom attitude.

Title: A storage device for a temporary unwinding of a portion of the warp from the beam on a warping or beaming machine
IPC: D02H3/00
Filed: 1942-07-24
Abstract: 563,855. Warping and beaming yarns. LAMBACH, F. July 24, 1942, No. 10374. Convention date, Nov. 21, 1941. [Class 142 (iv)] A device for holding a temporary unwinding of a portion of the warp 34 from the beam 44 of a warping or beaming machine, e.g. upon yarn breakage between the creel and the beam, comprises a set of stationary rollers 56 and a second set of rollers 76 mounted upon a vertically movable carriage 64 so as to move from an upper inactive position to a lower gripping and active position. A reversible electromotor 480 is provided for moving the carriage, and the rollers 76 in moving from inactive to active position draw a portion of the warp into the device in zig-zag form so that the ends of the broken yarn or yarns may be readily tied to each other. The warps can be clamped by a board 110 mounted upon an arm 106 of the carriage 64 so that it can be deposited upon a stationary board 102 shortly before the rollers 76 contact the warps. A reversing switch 497 having a forked portion 140, 142 is provided for controlling the electromotor 480, and a control member 138 is provided upon the carriage 64 to engage abutments 132, 136 upon a rod 118 in the extreme positions of the carriage so that a finger 124 on the rod engages the forked portion 140, 142 and moves the switch 497 to off position. A contact member 491 for an inching speed switch 490 for the driving motor 46 of the beam 44 is mounted upon the carriage 64 so that only when the rollers 76 are moved from their upper and inactive position can the motor 46 be inched round. An auxiliary start switch 492 of the motor 46 is also arranged on the carriage 64. A contact member 495 is integral with the arm 140 of the switch 497 so that, when the reversing switch 497 is moved to move the rollers 76 from their active lower position, the auxiliary switch 492 is in the on position to start the motor 46. A control switch 494 arranged in series with the auxiliarv start switch 492 is controlled by a member 495 secured to the movable clamping board 110, so that operation of the motor 46 of the beam started by the auxiliary start switch 492 can continue only so long as the board 110 is in clamping position. The carriage 64 may be open at one side parallel to the warp so as to permit free access to the warp when the rollers 76 are in their inactive position. The motor 46 is stopped upon breakage of yarn and a brake is applied to the beam 44 as described in Specification 563,856, and the switches 490, 492, 494 in the electrical circuits may be arranged as described in Specification 563,857, [Group XXXVII].

Abstract: 579,738. Gramophones. BRUSH DEVELOPMENT CO. July 31, 1942, No. 10774. Convention date, July 31, 1941. [Class 40 (ii)] [Also in Group XXXIX] In a piezoelectric gramophone pick-up for laterally-cut records, an arm 30 is attached to the crystal device 16 and carries at its end the stylus 15 and is made rigid horizontally and flexible vertically so that it yields vertically to the "pinch-effect" of the record groove and transmits to the crystal unit only the lateral oscillations produced by the record groove. The "pincheffect" is the reduction in the width of the groove normal to the groove which occurs at double frequency due to the recording tool oscillating radially on the disc during the recording. As shown in Figs. 2 and 3, the crystal unit comprises two plates 17, 18 clamped at the top between two pads 28 and along the vertical centre line of the sides between two pads 29 so that the unit can twist about its vertical centre line. The plates and the pads together with shims 26 are clamped in a recess 27 in an end block 36 of a pick-up arm 12 by a wedge 25 which is fastened by a screw 24. In a modification, Fig. 4, the side pads are only short pieces 42 at the bottom end of the unit, and this unit is clamped in a housing 41 which is secured to the pick-up arm by screws 43. In another modification, Fig. 9, the crystal unit is clamped at one end between pads 53 and the arm 30 is attached to its other end to produce bending instead of twisting of the crystal unit. The arm 30, which is to be rigid horizontally and flexible vertically, may be a flat solid strip, Fig. 9, a flattened cylinder, Fig. 6, or an assembly of wires 50, 51, Fig. 8. The arm 30 may be urged downwards by a blade spring 38, Fig. 2, a damping pad 39 being interposed between the ends of the spring 38 and of the arm 30, or may be loaded with a damping block 40, Fig. 6, of, for example, natural or synthetic rubber. The pick-up arm 12 has a curved nose 57, Fig. 2, extending over the arm 30 and closed at the bottom by a plate 46, which has a hole through which the stylus 15 projects. A pad 58 of felt or chamois leather is fitted under the end of the nose 57 to bear on the record to limit the pressure of the stylus on the record groove due to its spring bias.

Abstract: 394,108. Signal lamps. BRITISH POWER RAILWAY SIGNAL CO., Ltd., GLENN, S. L., and PIERCE, E. E., Windsor Works, Slough, Buckinghamshire. April 15, 1932, No. 10869. [Classes 75 (ii) and 75 (iv).] For preventing phantom indications from signal lamps the path of the entering and emerging light is divided into zones or sectors which are so arranged that clear and lightobstructing zones or sectors are diametrically opposite one another in relation to the optical axis of the lamp, so that any light entering through any one of the clear zones or sectors is, after reflection or refraction, intercepted by the diametrically opposite obstructing zone or sector. In the form shown in the Figure, a sheet metal disc 11 is stamped to form clear sectors 13 and intermediate opaque sectors 12. Such a screen may be placed immediately behind each of one or more lenses, whether or not the lenses are associated with reflectors, or it may be movable into operative position only when the light source is extinguished. Alternatively, such a screen may be associated with each of the colour filters of a multicolour signal lamp. In other forms the electric lamp bulb, the reflector, or the front glass or lens may be treated to form clear zones or sectors, each of which is diametrically opposite to another which is made opaque, as by coating with lamp black, or made diffusing as by frosting, stippling, or by means of prisms.

Abstract: 835,291. Drawing and reeling wire. BARRON & CROWTHER Ltd. April 3, 1958 [April 3, 1957], No. 10927/57. Class 83 (4). A wire drawing and/or coiling machine comprises a drum and a spindle rotatably mounted coaxially, the spindle having secured to it remote from the spindle axis means for guiding wire on to the drum, and drive means operatively associated with both the spindle and the drum, so that, if one is prevented from rotating, the other will rotate, and if the other is prevented from rotation, the one will rotate in the opposite direction. In one form, Fig. 1, the drum 14 is rotatably mounted on the spindle 12 which is itself mounted on bearings 13 in a frame 33. A motor 16 secured to the inner surface of the drum carries a pinion 24 meshing with a gear 23 keyed to the spindle 12. Wire 21 passes through the spindle 12 and is coiled on to the drum by a pulley 18 mounted on an arm 17 carried by the spindle. Rotation of the drum is prevented by the counterbalancing weight of the motor 16. In a modification the motor is mounted concentrically with the spindle and the drum is normally prevented from rotating by the addition of a separate counterweight, which can however be removed, and the spindle then held stationary by a locking pin so that the drum is rotated. In another form, Fig. 4, the winding pulley 45 is carried by a plate 43 on which are also mounted five rollers 76-79 so that they extend over the drum 40 by increasing amounts and in operation urge the wire along the drum. In the modification shown in Fig. 6, the drum has two annular portions 86, 87 the latter being of slightly larger diameter. The plate 84 carrying the winding pulley 91 also carries a pulley 92 serving to take wire off the portion 86 and wind it on to the portion 87 where because of the larger diameter it will be under greater tension. In the vertically arranged machine shown in Fig. 8, the motor 108 is eccentrically mounted within the drum 106 and drives a gear 112 keyed to the spindle 101 through a belt 109 and gear 111. Beneath the drum is a rotatable platform 113 carrying a wire receiver which is also locked to the drum by latches 117. Either the drum or the spindle may be held stationary by a latch 115 or a pin 121 respectively.
