Title: Improvements in weight indicating devices connected with the poise weights of steelyards
IPC: G01G23/00
Filed: 1923-12-08
Abstract: 228,307. Avery, Ltd., W. & T., and Sykes, C. M. Dec. 8, 1923. Steelyard apparatus. - In a weight-indicating device of the kind wherein the major order of weighment is obtained by traversing a poise weight along a steelyard and the minor order of weighment is obtained by an automatic resistant (such as a pendulum) connected to an indicating pointer, the major weight numerals are displayed in juxta-position to the minor indications, and are situated upon an indicator which has its point of indication, or its point of connection to the poise weight, located in the vertical plane containing the line of the fulcrum knife-edge of the steelyard. As shown in Fig. 1, the poise weight a carries an indicating bar b the numerals on which are displayed singly at an aperture d as the poise is moved along the steelyard c. The aperture d is situated vertically below or in line with the fulcrum knife-edge c<1> of the steelyard. A scale of minor order weight indications is arranged adjacent the aperture d and the minor order of weight is indicated by an automaticallyoperated pointer f. In a modification, Fig. 2, a rack g is pivoted to the poise weight, and meshes with a pinion j at the fulcrum line of the steelyard. The spindle k of the pinion is' carried by the scale housing and bears an indicating disc o arranged to display its numerals through an aperture d. The minor order chart of indications (not shown) is arranged adjacent the aperture d in a manner similar to that shown in Fig. 1.

Abstract: 409,693. Thermionic valves. FREEDMAN, P., 6, Hillside Gardens, Highgate, London. Nov. 2, 1932, No. 30916. [Class 39 (i).] In a valve having a control grid surrounding a cathode, an anode in two sections on the opposite sides of the control grid, and a screening member surrounding each anode section, each screening member consists of a tubular metal box having a perforated or grid structure on the side facing the control grid, and an imperforate structure on the opposite side. As shown, the control grid 6 is wound around supports 7 and encloses a V- or W-shaped filament cathode 1. Each screening member consists of a dished plate 10 and a frame 16 with wires 22 secured between flanges 15 on the plate and frame ; or the wires may be replaced by gauze or perforated metal. The wires and plate are grooved vertically at 17 or horizontally to receive strips 18 of mica, porcelain or steatite provided with lozengeshaped slots receiving projections on the sides of the anode sections 8, 9. The screening members are closed at the top and bottom and connected together by plates 11 with lugs 14 welded to supports 13. Each anode lead 19 passes through a large aperture in the plate 11 and through an insulator 20 on the plate ; or the insulator may be omitted and the lead screened by a metal tube welded to the plate. The filament may be provided with a mica damper 21 carried by a support 3. According to the Provisional Specification, the screening members may be made wholly of open-work construction.

Title: Improvements in or relating to means for measuring yarns during unwinding and rewinding thereof
IPC: B65H61/00
Filed: 1933-11-07
Abstract: 428,076. Measuring stop - motions. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and FULTON, S. M., c/o British Celanese, Ltd., Spondon, near Derby. Nov. 7, 1933, No. 30924. [Class 120 (ii)] Apparatus for unwinding a predetermined amount of yarn from bobbins having a substantially constant amount of yarn in each layer, comprises a guide traversed by the yarn and means driven by the guide to actuate a stop motion after a predetermined number of traverses. The yarn 12, Fig. 1, being unwound traverses the guide 13 pivoted at 17, whereby two pawls 18, 19 rotate the ratchet wheel 20, gears 24, 25 and the notched disc 27. A weighted lever 30, Fig. 3, pivoted at 31 has a projection 32 adapted to rest on the periphery of the disc 27. After one revolution of the disc 27, the projection 32 drops into the notch, the lever 30 rotates and the wire 35 swings into the path of the abutment 36 on the traverse rod 37 of the winding up apparatus. The next movement of the traverse rod pushes the wire 35 against the latch 38 and so moves the pivoted lever 39, withdrawing the latch 41 from the lever 42 secured to the usual starting and stopping rod 43, whereby the machine is stopped. To prevent tripping of the stop mechanism when recommencing, before the projection 32 has ridden out of the notch in the disc 27, a wire 45 interposes itself between the wire 35 and the abutment 36; as winding proceeds, the wire 45 is withdrawn.

[Class 100 (ii).] In inking- mechanism for reciprocating bed machines wherein ink is supplied from a set A of distributer rollers rotating constantly in one direction to a set B of forme rollers rotating in opposite directions alternately with reversal of travel of the bed, a swinging ductor roller 20 in constant rolling contact with the drum 8 is adapted to transfer ink to the forme rollers during both directions of rotation. In one direction of rotation the ductor 20 transfers ink directly to the roller 19 but upon reversal of travel the swinging arm 22 drops and ink is transferred indirectly through the companion ductor roller 21. Alternatively the roller 20 may be adapted to contact with two rollers of the forme set alternately. The messenger 9 supplies ink to the drum 8 at an intermediate stage when no ink is being transferred to the forme set. In a modification, the last roller of the distributing set A may be in constant operative contact with the distributer drum.

Abstract: 996,081. Reciprocating pumps and motors. RECHERCHES ETUDES PRODUCTION R.E.P. Aug. 15,1962 [Aug. 19, 1961], No. 31380/62. Heading F1A. In a rotating cylinder block swash plate pump or motor, the block 4 rotates about a member 34 an inlet sleeve 15 and an exhaust sleeve 16. The inlet sleeve 15 (Fig. 5) has ports 17 connecting the inlet conduit 11 with the pump cylinders 5. The sleeve is subjected to the discharge pressure of the cylinders on the surface 22 and this pressure is balanced by the provision of grooves 26 which are supplied with pressure liquid via passages 27. The exhaust sleeve 16 (Fig. 12) is subjected internally to the liquid pressure where no ports are provided. This pressure is balanced by supplying grooves 29 with pressure liquid via passages 31. The axial thrust due to the pressure in the cylinders is balanced by subjecting the surface 49 (Fig. 1) to outlet pressure, the liquid being taken from one of the grooves 29 which is joined to an axially extending groove (Fig. 15 not shown). The sleeve 15 is prevented from rotating by means of male members 45 engaging in corresponding female recesses 46 in a sleeve 12 forming the inlet conduit. The sleeve 12 carries a flange 38 in which are formed female recesses engaging male projections on the exhaust sleeve 16, to prevent the sleeve rotating. In an alternative embodiment (Fig. 20), the inlet sleeve 74 and outlet sleeve 75 are mounted on an extension of the driving shaft 64. The radial thrust due to the pressure liquid in the orifices 72 acting on the sleeve 74 is balanced by supplying pressure liquid to grooves 90. Similar grooves are provided in the sleeve 75 except that these extend around that part of the sleeve opposite the outlet apertures. Rotation of the sleeves 74, 75 is prevented by pins 79, 80. The axial thrust of the pressure in the pump cylinders is balanced by applying the liquid outlet pressure through. a conduit 96 to the end of the shaft 64.
