Filed: 1944-09-19
Abstract: 586,937. Photo-electric apparatus for examining transparent vessels. UNITED DARIES, Ltd., and STOATE, N. P. Sept, 19, 1944, No. 17882. [Class 40 (iii)] In apparatus for detecting foreign bodies on the bottom of a transparent vessel by means of a beam from a lamp 10 directed longitudinally through the vessel to a light-sentitive device 13 located in a compartment 12 of a casing 4 rotated. by a motor 16 and in which the vessel is rotated about its longitudinal axis by the engagement of its periphery with a flexible, inelastic band 21, Fig. 1, the scanning of the bottom of the vessel is effected by the combination of a radial slit 11 in a platform 6 on the rotating assembly and a spiral slit 33 in a fixed screen 31, the .slit having a length such that it co-operates with the slit 11 during a number of revolutions of the vessel. A lens 35 projects an image of a part of the fixed slit 33 on to the part of the moving slit 11 with which'it is instantaneously in register. The radial slit 11 may extend towards or away from the axis of rotation of the assembly and in the former case the operative beginning of the slit 33 is disposed above the outer end of the slit 11 and the final portion of the slit 33 co-operates with the inner end of the slit 11. The final portion of the slit 33 is preferably of constant radius for a length corresponding to the circumference of the vessel so that the peripheral portion of the bottom is scanned more completely. The slit 33 may be formed by a number of arcuate slits of decreasing or increasing radius with their ends merging so as to prevent light from being cut off from the associated photo-electric cells. The general operation and constructional details are as described in Specifications 586,935 and 586,936 apart from a guard ring, Fig. 3 (not shown), additional to the ring 53 to prevent the magnet 40 being actuated by the interruption of the light beam by the ends of the fixed screen 31. If the stepped arcuate slits do not merge at their ends additional guard plates are provided to prevent the operation of the magnet 40 consequent upon the interruption of the beam of light by the solid portions connecting the constituent arcuate slits. Specifications 586,938 and 586,939 also are referred to.

Title: Improvements in or relating to gas filled electric discharge devices
IPC: H01J17/56
Filed: 1955-06-21
Abstract: 798,627. Thermionic cathode tubes. M-O VALVE CO., Ltd., and ISAACS, G. G. June 21, 1956 [June 21, 1955], No. 17999/55. Class 39(1). In a gas-filled tube, of the kind including an anode, a cathode, and an auxiliary electrode causing a constriction of the effective cross-sectional area of the path available for the discharge, the parts of the auxiliary electrode adjacent the constricted region of the discharge path are connected by paths of high thermal conductance to at least one metallic surface arranged to be cooled by the forced circulation of fluid. Differential lowering of gas density in the constricted region is thereby minimized. A hydrogen-filled thyratron has a cylindrical, copper envelope 1, in which is mounted a cathode 2, an anode 5 and a control electrode consisting of two identical nickel plates 6 and 7. Interposed between plates 6 and 7 are two copper plates 13 and 14 which are separated by a copper disc 18 and a copper ring 17. Holes in plates 6 and 7 are aligned with larger holes in plates 13 and 14 respectively and the two sets of holes are circumferentially offset so that together with the gap between 17 and 18 they provide narrow tortuous channels through which the discharge passes. The plates 6, 7, 13 and 14, the ring 17 and the disc 18 are in good thermal contact with each other and with the envelope and are cooled by means of forced circulation of water through a tubular copper helix 20. The device operates down to 0À2 mm. pressure. The invention is also applicable to rectifiers, in which the auxiliary electrode is a baffle integral with the anode or cathode. Where the envelope is of glass the auxiliary electrode may be connected to an external cooled surface by heat conductors sealed through the glass.

Title: Improvements in gas-control devices for use in respiratory apparatus
IPC: A62B9/02
Filed: 1938-06-21
Abstract: 516,147. Fluid-actuated valves. OSTORERO, R. June 21, 1938, No. 18476, Convention date, June 22, 1937. [Class 135] [Also in Group VI] In an apparatus for administering gases the supply of gas is controlled by levers of the first order pivoted to move in the same plane and actuated to control a gas valve by the contraction or expansion of a flexible bag which is effected through the act of breathing. A vessel containing gas under pressure being connected to a nipple a a valve C is opened by turning a knob B to admit gas by way of a bore in the valve part C and conduits I, L in the casing and in a spindle M respectively, its egress being prevented by the member n against which the spindle M presses. The casing N of the spindle M is movable against the stress of a spring P and has orifices r, r communicating with the interior of a flexible bag V enclosed in a casing y and with an outlet q to a mask by way of a diaphragm valve K. Levers R carrying disc members v are pivoted at S and have lugs T projecting from their lower extensions which engage a conical recess O in the end of the casing N. When the pressure is reduced on the outlet side of the valve K by inhalation of the user this valve opens and, communication being established through passages r, r with the interior of the bag, this collapses and acts on the upper ends of the levers which move towards each other, thus causing their lugs T to act on the conical part O to move the casing N and allow gas to issue through slots z round the member n and through passage r to the outlet. On exhalation the valve K is closed and pressure rises within the casing sufficiently to inflate the bag, whereon the levers move together'under the action of a spring and the casing N returns to normal position and stops the emission of gas. A continuous emission of gas may be obtained by turning a ring B<2> threaded on the knob B till it engages a lever C<2> which acts on one of the levers R and moves it so that the member N is moved to open position. The vessel connected to the nipple a may be filled with gas under pressure by attaching a supply pipe to a neck E and opening the valve C so that conduits F, D are put in communication. A pressure gauge G is provided.

Abstract: 239,670. Jackson, W. J. Mellersh-, (Taylor, A.). Aug. 5, 1924. Aerials; directive signalling; coupling oscillating and radiating circuits. - With the object of promoting efficiency in radiation, and of eliminating earth losses, the transmitting-aerial comprises a series of ungrounded loops 2, 3, 4, either coplanar or in parallel planes. As shown in Fig. 2, each loop comprises a tuning inductance 8, a condenser 14, and an ammeter 9, the condensers 14 being connected across bus-bars 12, 13 energized by an arc or other oscillator 15. The loops are co-planar and are energized in phase, so that the currents in adjacent vertical members are in opposite direction and are ineffective as regards radiation. The mutual induction between the loops is low. When the loops are placed in parallel planes, they should be at sufficient distances to minimize the mutual inductance. The oscillator circuit may be magnetically coupled to the inductance 8 of the first loop 2, the other loops being energized via. the bus-bars 12, 13; or separate high-frequency alternators, linked mechanically or otherwise to keep them in phase, may energize the respective loops. The condensers 14 preferably have an air dielectric, and may comprise layers of wire strung from telegraph poles. Radiation is a maximum in the plane of the loops, and a minimum at right angles thereto. Two multiple-loop systems may be set up at right angles to each other, and used for sending separate messages in different directions, or the same message in all directions.
