Title: Improvements in or relating to electric counting apparatus
IPC: H03K21/00
Filed: 1953-06-19
Abstract: 738,218. Electric counting-apparatus. GENERAL ELECTRIC CO., Ltd., and BAYLISS, A. J. June 4, 1954 [June 19, 1953], No. 17059/53. Class 106 (1). [Also in Group XL (c)] In electric counting-apparatus of the reversible type comprising means for applying positive-going impulses to the first of cascaded similar stages, each stage comprises a cold cathode gas-filled discharge valve V1, V2 ... Vn, an electromagnetic relay A1 &c., having a two-position contact AC1 &c., and so arranged that current through a first winding AA1 &c., connected in the main discharge circuit of the valve, causes the contact to move from the " off " position (as shown) to the " on " position except when current is passed simultaneously through a second winding AB1 &c., the input lead IL1 &c. of the stage being connected by the relay contact in the " off " position to the trigger electrode circuit of the valve and to a circuit for the second relay winding, and by the contact in the " on " position to the cathode circuit of the valve, and a two-position contact BC1 &c. (except for the highest stage), controlled by a single reversing relay common to all the stages, the output lead OL1 &c. being connected by this contact in the forward or backward counting position to the input lead of the stage, when the contact AC1 &c. is in the " on " or " off " position respectively. As shown, the contacts BC1 &c., are in the position for forward counting, and positive pulses are applied to the lead IL1 for the first stage by closing contact IC. The first such pulse will be applied through resister RB1 to relay winding AB1, and through resistor RA1 to the trigger electrode of valve V1 which will then fire, the discharge current flowing through winding AA1. When the pulse ends, current ceases to flow through AB1 and relay A1 operates. Contacts AC1 thus direct the next pulse through rectifier W1 to the cathode of VI, which is thus extinguished, and also to winding AA1 so that the relay remains operated until the end of the pulse. A capacitor C1 ensures that a positive potential is maintained on the cathode for a sufficient time to enable the gas in V1 to be de-ionized. The higher stages operate similarly, every second pulse from IC being applied through IL1, AC1, BC1, CL1 to the input lead IL2 of the second stage and so on. The registered count may be indicated by causing proportional currents to flow through an ammeter.

Abstract: 501,439. Phase - difference measurements. SANTUCCI, G. June 24, 1937, No. 17661. Convention date, June 24, 1936. [Class 37] [Also in Group XL] Two forms of mount. ing for the coil of a phase difference indicator are indicated in Figs. 2 and 3. In the embodiment shown in Fig. 2, the indicating coil I is connected by flexible leads K.to the coil N. When the indicator tends to move into a new position, the coil I is retarded only by the pull of the flexible leads K and moves at once into its new position. The coil N follows when the force exerted is sufficient to overcome the frictional drag of the brushes g, h on the rings e, f. In the embodiment shown in Fig. 3, the coils I and N are mounted with their windings in opposition so that the e.m.f's induced in them by the rotating field cancel. When the coils move out of the posi-. tion of equilibrium however they tend to move in opposite directions but the contact bar s, t carried by the coil N brings in one or other of the additional windings P, R, which forces the coil N to follow the coil I into a new position of equilibrium.

In a switch of the type described in the parent Specification, the magnetic shunt paths are provided by one or more suitably deformed sheets of magnetic material extending from one contact spring terminal to the other. As shown, Fig. 2, the contacts, enclosed in tubes, pass through horizontal and vertical operating coils A, C, and a horizontal hold coil H1. The metal sheet 5 comprising the magnetic shunt has troughs 6 to accommodate the horizontal coils and slots to accommodate the vertical coils. The portion of the plate 5 adjacent the contacts is brought close thereto and further portions 15 of the plate are bent at right angles round the contact sets in order to increase the shunt effect. Furthermore the extreme left-hand portion is brought close to the terminals 1, being separated only by a thin strip of insulating material 7. At the other end the plate 5 is kept sufficiently far away from the terminals to all the whole contact set to be withdrawn. The magnetic circuit at this end is completed by a plug-in arrangement, Fig. 3, comprising an insulating holder 10 for the terminals and the attached soldering contacts 9, an insulating plate 11, and plate 12 of magnetic material having fingers 14 adapted to embrace the member 5. The plug in members may be enclosed in a moulded member common to all the contacts between two plates 5. The coil A may be provided with a conducting strip 23, apertured to accommodate the contact sets, this strip acting as a short-circuited winding to make the contacts slow to operate. The vertical coils may have moulded protective covers 18. Alternatively, the covers may be of conductive material again in order to slow up the response of the contact sets. Further magnetic shunt strips 16 may be inserted between contact sets as described in Specification 830,317. In a modification, Figs. 6, 7 (not shown), the vertical coils are replaced by individual coils for each contact set, all the coils in a vertical set being arranged to be energized simultaneously.

Abstract: 145,681. Goodyear Tire & Rubber Co., (Assignees of Harsel, W. B., and Nall, E. A.). Nov. 3, 1917, [Convention date]. Tyres, elastic, special apparatus for making.- Relates to machines of the kind described in Specifications 120,563 and 120,564 for building-up the fabric foundation of a tyre cover on a rotating mandrel. The present invention is concerned with means for rolling-down the tread portion of a fabric ply before the operation of the main stitching ' rolls (114). In the form shown in Figs. 1 and 2, the coned rolls 96 are pivoted by bolts 98 on a bracket 103 carried by the piston 104 of a power-cylinder 105. The valve 108 for controlling the admission of pressure-fluid to the cylinder 105 is opened at the commencement of the forward travel of the carriage 58 by a tappet 113 thereon engaging the valve-rod 108a. This momentary opening of the valve admits sufficient fluid to the cylinder 105 to bring the rolls 96 into operative position against the mandrel, the spreading of the rolls, due to the contour of the mandrel, being yieldingly resisted by springs 101. Fig. 4 shows a modification in which the treadrolls 254 are mounted on racks 256 operated by meshing pinions 261. A pinion 263 fast on the spindle of one of the pinions 261 engages a sliding rack 264 the movement of which, by a hand-lever 266, determines the operative or inoperative placing of the rolls with respect to the mandrel.

Abstract: 1,219,493. Forming an annular flange; welding by fusion. PIRELLI GENERAL CABLE WORKS Ltd. 31 March, 1969 [17 April, 1968], No. 18084/68. Heading B3E and B3R. Apparatus for forming a radially extending annular flange 8 in a metal cable sheath 4 comprises two annular tools 6 and 7 adapted to engage two spaced apart circumferential regions of the sheath 4 and means (not shown) for moving the tools 6 and 7 relatively towards each other along the sheath axis so as to form between the tools an annular radial flange 8 projecting outwardly from the sheath. The deformation of the cable sheath to form the radial flange 8 will tend to cause a shortening of the sheath 4. Such shortening can be avoided in the case of a corrugated sheath by swaging down some of the corrugations adjacent the side of the flange. To ensure uniformity of the size of the flange 8 the deforming tools are of the shape shown in Fig. 6 at 61 and 71 in which the tool 61 overlaps the other and is formed with an outer cylindrical surface 22 which limits the radially outward deformation of the sheath. In order to weld a component to the flange 8, the flange is located between a pair of jaws 9 and 10 (Fig. 3) which when moved towards each other press the two abutting portions of the sheath wall forming the radially inner part of the flange 8 into sealing engagement, thus isolating the radially outer part of the flange from the interior of the sheath. A component 14 having a flange 15 is placed over the end of the cable with the flange 15 in face to face abutment with the radially outer part of the flange 8 on the sheath 4. The two flanges 8 and 15 are held together by axially movable clamps 16 and 17 which also serve as heat sinks for conducting away the welding heat, and a continuous weld 18 is effected at the outer edges of the abutting flanges.
