IPC: B65D43/16
Filed: 1931-04-25
Abstract: 377,708. Hinges. PARTIOT, M., 17, Rue Albert Joly, Versailles, France. April 25, 1931, No. 12309. Convention date, April 26, 1930. Addition to 363,177. [Class 65 (ii).] In a metal box with a lid hinged as described in the parent Specification, one or each of the members is provided with a projection which engages the other member to prevent the lid from opening to a position which allows of disengagement. The box 1 has two knuckles 5, 6 and a depressed part 4 between them, and the lid has one edge 9 shaped to form two hinge pins such as 8, and also has a projection 13 ; the knuckle 5 has a slot 11 in its lower edge. The lid is attached as follows : one pin is inserted into the knuckle 5 so that the edge of the metal adjacent to the pin enters the slot 11, as shown in Fig. 2, and the other pin 8 is moved downward into the horizontal plane of the knuckle 6 ; the position is then as shown in Fig. 3, the projection 13 bearing against the part of the box below the depression 4 ; the edge 9 is now slightly bent, being sufficiently springy, to bring the pin 8 into line with the socket, and the lid is then slid along to insert the pin. The lid cannot be disengaged without similar distortion. The projection 13 may be formed on the box instead of the lid, or shallow projections may be formed on both members. Instead of pressing out a projection, the wall of the member may be bent outwards between the hinge pins or knuckles, or may be sloped outwards from the hinge axis. In a modification, the pins may project inwardly.

Title: Improvements in winding apparatus for balls of textile sliver
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H67/04
Filed: 1967-03-16
Abstract: 1,204,885. Winding sliver balls. JAMES MACKIE & SONS Ltd. 12 March, 1968 [16 March, 1967], No. 12448/67. Heading DIN. A sliver ball winding apparatus comprises a driving roller 15 which rotates ball 14 on rotatable spindle 16 to which the sliver is fed by a traversing nozzle 12 and a doffing mechanism for the completed ball which has controls to move the spindle 16 and completed ball 14 to a position which is axially spaced from the winding position by a distance greater than the axial dimension of the ball (see Fig. 2). A gripping member 106 is provided to engage the ball and prevent its return movement, (see Fig. 3). The spindle 16 is withdrawn axially from the ball so as to doff and return to a position adjacent the driving roller 15 for the start of a new ball. As shown, when yardage counter 18 indicates a complete ball has been wound, main motor 20 is stopped and auxiliary motor 22 started to drive the machine at a slower speed. Also bar 44 is moved into the path of the traversing nozzle 12 and is pushed to the right against spring 52. This causes the traverse and auxiliary motor 22 to stop and allow the last part of the sliver to be wound without crosswind. The ball 14 and spindle 16 is then swung away from the driving roller 18 and is moved to the left by pneumatic cylinder 88 acting on supporting frame 76. The leftward movement causes bar 44 to press against the sliver ball and trap the end thereof and causes knife 102 to sever the sliver end, holding plate 106, gripping a previously wound ball 14', is raised and ball 14' is pushed along and its place is taken by ball 14. Plate 106 is then lowered and the support 76 and spindle 16 return to the right to the winding position. If desired spindle 16 can be caused to pull a rigid tube into the centre of ball 14 as it returns, see Figs. 4 and 5 not shown. Bar 44 is raised away from the spindle to the inoperative position, knife 102 is swung back and spindle 16 is moved against driving roller 15 as the spindle returns to the winding position. The winding process is then restarted with the spindle 15 being pressed extra hard against roller 15 as the first layers of sliver are wound.

Title: Improvements relating to control valves for fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1928-04-30
Abstract: 294,140. Westing house Brake & Saxby Signal Co., Ltd., (Assignees of Compagnic des Freins Westinghouse). July 18, 1927, [Convention date]. Fluid-pressure.-In a control valve mechanism for fluid-pressure braking apparatus comprising two valve elements which respectively control communication between the brake cylinder and the atmosphere or a source of pressure-fluid or vacuum, the valve which controls the communication with the atmosphere is constituted by a resilient element such as a rubber or leather disc. The valve device is shown as mounted on the brake cylinder head 2 and for a vacuum brake, the vacuum being produced for example by the engine of a vehicle. The control rod 12, guided by the link 13 pivoted at 14 to the fixed bracket 15, carries a conical collar 16, between which and a slidable sleeve 10 is interposed a spring 19. The sleeve 10 is secured to a diaphragm 4 the outer edge of which is held between parts 3, 5 of the valve casing. A spring 20 is interposed between a flange on the sleeve 10 and the casing 5. A valve disc 23 of rubber, leather or other resilient material is mounted on a poppet valve 24 adapted to seat on the upper edge of the fixed part 25. The chamber 26 below the valve 24 is connected to the induction pipe of the engine of the vehicle. Normally the parts are in the position shown so that the brake cylinder is open to the atmosphere through the ports 7, 9. To apply the brake the rod 12 is pulled upwardly, thereby raising the sleeve 10 through the spring 19 until the flange 22 on the sleeve engages and raises the disc valve 23 and with it the valve 24. The brake cylinder is thus cut off from the atmosphere by the seating of the valve 23 and is connected to the induction pipe of the engine by the opening of the valve 24. When the vacuum established in the brake cylinder, acting on the diaphragm 4, corresponds to the upward effort on the rod 12, the diaphragm moves downwards sufficiently to seat the valve 24, the disc valve 23 remaining seated to hold the brakes applied. By raising or lowering the rod 12 the degree of vacuum established in the brake cylinder can be graduated as desired. The disc valve 23 being made of resilient material permits of this valve and the valve 24 remaining simultaneously closed during a limited range of movement of the control rod 12, thereby preventing pulsation and irregular action of the valves in operation.

Abstract: 1426552 Measuring salinity electrically ROBERTSON RESEARCH INTERNATIONAL Ltd 16 March 1973 [18 March 1972] 12774/72 Heading G1N In a conductivity measuring apparatus e.g. for measuring salinity, of the type in which the coupling between the windings of a transformer is dependent upon the conductivity of a liquid in which the transformer is immersed, the output from the secondary winding is amplified and rectified before being applied to a meter. The electrostatically isolated windings are wound on respective toroidal cores coaxially mounted alongside one another and with the windings completely encapsulated in plastics material but leaving a free path through their central apertures for passage of liquid under test therethrough. The primary winding is energized by an A.G.C. oscillator and the output from the secondary winding after filtering and amplification is superimposed on a D.C. signal representing temperature derived from a bead thermistor mounted adjacent the transformer. The signals are applied over a three core cable to a receiver and indicator unit where after filtering out noise and blocking the D.C. component, the A.C. signal is fed to a phase splitter feeding a push-pull transistor amplifier. The output of the push-pull amplifier is rectified and applied to a microammeter. The D.C. signal is applied to the microammeter to give a direct reading of temperature. The salinity of the liquid can then be directly obtained from standard tables for given temperature and conductivity values.

IPC: G01N3/58
Filed: 1916-09-14
Abstract: 108,760. Fremont, C. Sept. 14, 1916. Filing machines and apparatus, reciprocating.-The file is reciprocated horizontally with its cutting face downwards against an intermittently-rotated test-bar, the filings from which are collected, and a diagram is drawn of the stroke of the file plotted against the force required to propel it. A hand or power driven shaft h, Fig. 1, carries an adjustable crank-pin which drives a cross-head 4 upon which is mounted a spring- pressed socket 6, Fig. 5, in which the tang of the file is fixed. The deflection of the spring 30 is a measure of the propelling force and is transmitted through a rod 38 to the shaft 32 of a pencil-carrying arm 34 which records upon a board 36; the pencil thus partakes of a movement combined of the stroke of the file and the propelling force. A counter 44 indicates the number of the strokes of the file. To calibrate the spring, the socket 6 is moved to the vertical position shown in Fig. 3, and a stud 41 is inserted; a weighted saddle 42 bears against the stud and the deflections of the spring for known weights are recorded upon a lower board 40. The recording-apparatus can be dismantled by driving a wedge 45 into the spring socket, thus causing a cam-slotted arm 49 to lift the pencil off the paper.
