Title: Improvements in linking machines
IPC: D05B7/00
Filed: 1958-04-15
Abstract: 857,227. Sewing-machines. UNDERWOOD. F. E., and PERRY. E. H.. [trading as UNDERWOOD & PERRY]. April 7, 1959 [April 15, 19581. No. 11945/58. Class 112 A linking machine has an oscillatory pusher operable to progressively push work off the radially extending points 4 on the rotary dial 1 as the work passes through the stitching mechanism. The pusher 17, which may comprise a flat block of an acrylic ester product, has an oblique front edge 17a and is secured in a metal holder 18 fastened directly to .the needle actuating lever 6 by a screw. The holder 18 may be turned about this screw to adjust the height of the pusher. As the pusher partakes of the same oscillatory motion as the needle it imparts to the progressing work a series of thrusts to sweep successive portions of the linked parts radially outwards off the points 4, the work then being guided downwards beneath the looper operating lever assembly by a sheet metal guide 20. An ear-like protuberance 20b provided on the guide extends beneath the pusher and above the points. An uncurling guide 21 of similar material to that of the pusher is fixed to a stationary clamp ring 2 to prevent the work being linked from turning over into the path of the needle. Stitch forming device. The looper 8 is mounted on a slidable lever 9 having two rollers which engage with front and rear rotary cams 10 and 11. The looper 8 is cranked at its operative end to permit the looper lever assembly to be set back to provide adequate space at X to permit the passage of work pushed off the points and guided downwards by the guide 20. A guard 28 prevents this downward moving work from fouling the looper lever assembly, while an outer guard comprising an open loop 22 of thin metal or wire secured to a guide plate 23 prevents the work from fouling the looper itself. The edge 23a of the guide plate forms a lead in for work moving towards the stitching position.

Title: Improvements in or relating to liquid contents gauges
Inventor: ELLIS WILLIAM VERNON
IPC: G01F23/14
Filed: 1963-03-27
Abstract: 1,014,738. Determining liquid contents electrically. S. SMITH & SONS (ENGLAND) Ltd. May 29, 1964 [March 27, 1963], No. 12023/63. Heading G1N. A liquid contents gauge for measuring the amount of fuel in an aircraft tank, and which has compensation for the acceleration and banking of the the aircraft, comprises a plurality of pairs of differential pressure transducers 2, 3 (Fig. 1) and an accelerometer 23 (Fig. 2), each transducer 3 being mounted at the top of the tank directly above a transducer 2 located at the bottom of the tank. The transducers 3, 2 thereby detect the pressure difference with respect to the atmosphere at the upper and lower levels of the tank respectively. The sum of the differential pressures measured by transducers 2 minus the sum of the differential pressures measured by transducers 3 is proportional to the mass of liquid in the tank. Diaphragms 4 divide each transducer into chambers 5, 6, atmospheric pressure being communicated to chambers 5 to the tank space above the liquid level by pipes 7, while orifices 9 communicate environment pressure to a respective chamber 6. The diaphragms are respectively coupled to the movable plates of capacitors 2a, 3a, which capacitors are included in a circuit (Fig. 3) which summates the differential pressures. A variable capacitor 18 is the output member of the accelerometer 23 (Fig. 2) comprising a weight 24 on a diaphragm 25 and the accelerometer modifies the output signal of the summating circuit in accordance with any deviation of the said acceleration from that normally exerted by gravity when the tank is in its datum position. The capacitance of C18 is proportional to the acceleration exerted on the liquid fuel multiplied by the cosine of the angle of deviation # of the liquid level from horizontal. In operation of the circuit, if there is a potential above earth at a terminal 16 (Fig. 3) this is applied to a servo amplifier 19 which energizes a motor 20 to drive a wiper arm on a resistor 17 in a direction to change the value of the current through C18 soastobringthepotential of the terminal 16 to earth. An indicator 21 mechanically coupled to the motor indicates the position of the wiper and thus the magnitude of current in C18 which is equal to the difference in the currents flowing through C2a and C3a and thus to the mass of liquid in the tank. Instead of capacitors 2a, 3a variable inductors may be used.

Abstract: 1,192,761. Lining bar for press filter. ROSE, DOWNS & THOMPSON Ltd. 11 March, 1968 [15 March, 1967], No. 12051/67. Heading B1D. Lining bars which form the filtering surface of a rotary screw extrusion press or ram press for vegetable matter each comprise an elongated metal body 19 with a wear-resistant facing 22, of glass or ceramic, adhered, keyed or screwed thereto. The facing may comprise axially abutting sections (Fig. 1, not shown) so that the bar can bend without fracturing the facing. The body has axially spaced, wedge-like extensions 21 which abut the adjacent bar, when the bars are arranged to form a press cage of cylindrical shape, supported by two-part external rings within a closed housing (Figs. 3, 4, not shown). Among suitable facing materials are a mixture of at least 85% alumina with a vitrified ceramic, a glass containing at least 70% silica, and a ceramic matrix with silicon carbide embedded therein. In an extrusion press, the screw rotates so as to press facing 22 leftwards in Fig. 2, so as not to stress the Araldite (T.M.) bonding the facing to the bar, the force being borne by shoulder 20. Instead of straight bars, a cylindrical cage may be built up of coaxial rings, of otherwise similar construction to the bar described. Facings may be reground when worn.

Title: Improvements in or relating to signal separator devices
IPC: H03K17/74
Filed: 1960-04-05
Abstract: 900,028. Diode and transistor switching circuits. BURROUGHS CORPORATION. April 5, 1960 [April 23, 1959], No. 12067/60. Class 40 (6). A diode switching circuit comprises a plurality of individual input points connected through respective diodes 49, 51, 53, 55 to a common junction point so that the diode to which the greatest amplitude signal is applied alone conducts and passes that signal to the junction point, and also comprises a further diode 57 reversely connected with respect to diodes 49, 51, 53, 55 between the common junction point and an output point, the circuit being so provided with constant current devices constituted by transistors 18 and 23 that the voltage drop across whichever one of diodes 49-55 is conducting is equal to the voltage rise across diode 57 so that the D.C. level at the output is substantially the same as that at the operative input. A comparatively low-resistance potentiometer network 25, 27, 29 connected between sources 31, 33 provides substantially constant biasing voltages at the bases of PNP transistor 18 and NPN transistor 23 so that the emitter currents and hence the collector currents of the two transistors are substantially independent of the load conditions applied thereto. The transistors are so biased that the current through transistor 23 is twice that through transistor 18; hence assuming load resistor 20 is so large as to take a negligible current the current through the transistor 23 divides equally, one half flowing through diode 57 and transistor 18 and the other half through whichever one of the diodes 49-55 is conductive. Hence if all the diodes are of the same type and suitably matched the voltage drop across the conductive one of the diodes 49-55 will be exactly cancelled out by that across the diode 57.

Abstract: 1,135,277. Oxidation treatment of carbon black. CABOT CORP. 22 March, 1966 [23 March, 1965], No. 12440/66. Heading C1A. Carbon black may be oxidized with a nitrogenous oxidizing agent, e.g. HNO 3 , N 2 O 5 , NO 2 , N 2 O 4 , in a process characterized in that carbon black contacted with nitrogenous oxidizing agent is first established in a first zone maintained at temperatures of between 150‹ and 300‹ F. and then is continuously conveyed through an adjoining second zone in which the temperature is maintained generally in a range from 250‹ to 400‹ F., and through which a free oxygen-containing gas is continuously circulated in a direction countercurrent to the flow of the carbon black therethrough. The two zones may be in direct communication with each other and the carbon black is continuously agitated as it passes through them. In a suitable apparatus carbon black is charged via conduit 11 and screw 12 into rotating enclosure 9 which rotates about its longitudinal axis. Heat is supplied to enclosure 9 to raise temperatures therein to levels of 100‹ to 150‹ F. and above with a progressive increase in temperature along the length of the drum until temperatures of at least 300‹ to 400‹ F. are reached at the downstream end where the treated carbon black is removed though outlet 17. Zone 1 is the lower temperature and zone 2 the higher temperature zone. In Fig. 1 nitrogenous oxidizing agent is released into the black by means of conduit 13 to bring them in contact with each other in zone 1. Free oxygen containing gas is introduced through annular ring conduit 15.
