IPC: H01J31/49
Filed: 1947-07-04
Abstract: 664,592. Cathode-ray tubes. PYE, Ltd. June 14, 1949 [July 4, 1947], No. 17652/47. Class 39 (i). [Also in Group XL (b)] In an arrangement for producing a visible image from an X-ray image, a photo-electric tube includes a screen comprising the combination of a mosaic of photo-electric elements with fluorescent material adjacent the mosaic and operating to illuminate the elements under the impact of X-rays, an electrode for collecting photo-electrons released from the elements when illuminated by the fluorescent material, a signal plate capacitatively coupled to the elements and means for scanning the elements with a low-velocity electron beam. The X-ray image of an object 11 is projected on a target electrode 15 comprising a wire mesh 21 with a coating 24 of fluorescent material on the wires and the interstices filled with metallic plugs 22 carrying a coating of photo-sensitive material. The mosaic is scanned by a beam 16 of lowvelocity electrons deflected by coils, one of which is shown at 20, and a coil 19 providing a stray uniform axial field so that the electrons impinge at right angles on the mosaic electrode. The output is taken from the wires of the mosaic electrode and a collector electrode 25, which may be optically opaque, reflects the light image back to the photo-sensitive elements. The electrode 15 may be constructed by coating the wires with glass carrying a suitable fluorescent material in suspension and the apertures are filled with plugs of a suitable metal, e.g. antimony or silver, formed by an elutriation process, and coated with caesium. A modification, Fig. 2 (not shown), utilizes a photo-electric target comprising a thin sheet of transparent material, e.g. mica, coated on one side with a layer of fluorescent material on which is deposited a thin metallic coating constituting the signal plate. The other face of the transparent material is covered with a mosaic of insulated transparent photo-sensitive elements scanned by the low-velocity electron beam. In this modification, the collector electrode is formed by a coating on the inner surface of the tube, or a ring member. The scanning electron beam may be derived from a photo-cathode illuminated and. scanned by a flying light spot.

Title: An improved machine for classifying or automatically sorting or separating plates or other articles or materials according to weight
IPC: B07C5/20
Filed: 1932-06-23
Abstract: 400,345. Sorting by weighing. POWELL, J. O., 1, Argyle Avenue, Gorseinon, Swansea. June 23, 1932, No. 17788. [Class 143.] In an apparatus for sorting articles by weight, the weighing device is provided with means whereby the percentage departure allowed from the predetermined weight is maintained constant throughout the range of predetermined-weight settings. Means are also provided for varying the percentage allowed. In the apparatus shown, for sorting tin plates into correct, under and overweight, the plates from a cleaning machine pass over a roller 14 to an inclined pan 1 whereon they are retained by a pivoted stop 2. In passing over the roller the plates depress a link 15 and thereby couple-up a clutch so as to impart one revolution to a cam shaft 20. During the revolution, the weighbeam 29 first adjusts the height of a blade finger 47 suspended from the weighbeam by a rod 46, and a cam then rocks the rod towards two sliding blocks 50, 51. If the weight of the tin plate is too great or too small the blade finger engages one or other of the blocks and pushes it back so as to actuate to a predetermined extent a lever 54, rod 56 and deflector 52, thus setting the deflector in line with one or other of two trays 60, 60a for under and over weight plate respectively. If the plate is of correct weight the blade finger 47 passes between the two blocks 50, 51 and the deflector remains in its upper position leading to the tray 59. A second cam then actuates a lever 68 to swing down the stop 2 and allow the tin plate to slide down the deflector into its allotted tray. As the shaft 20 completes its revolution the parts return to normal position in readiness for the next operation. The apparatus is set to deal with articles of a predetermined correct weight by adjusting a poise 30 on the weightbeam, the adjustment being effected by a milled head 41 and screw 45. At the same time, the milled head adjusts a pendulum weight 39 in a vertical direction so as to ensure for all settings of the poise 30 the same angular deflection of the weighbeam for the same allowable percentage of over or under weight of the articles. The extent of the allowable percentage may be adjusted by varying the gap between the blocks 50, 51 by means of screw 63 co-operating with a dial 66. Instead of employing a deflector 52, the plates may be directed over two trap doors which are opened by the blocks 50, 51 to admit over and under weight plates respectively.

Filed: 1945-07-12
Abstract: 601,131. Fluid-pressure servomotor-control systems. BROWN, G. W. July 12, 1945, No. 17877. [Class 135] [Also in Groups XX and XXXV] A gyroscope 11 controlling the steering of a craft, e.g. by means of a servomotor having a control valve 14, is supervised by a magnetic compass or other directional device defining an azimuth datum, which acts through two or more separate means for precessing the gyro in azimuth at different rates, precession being at a low rate for small displacements and at a relatively high rate for large displacements, e.g. when the components of the controlling mechanism are adjusted to introduce a change of course. As shown, a card 18 is driven by a compass repeater 16. A pointer. 49 with associated contacts. 17 is frictionally coupled to the card 18 but may be adjusted to a desired course by the knob 52. Contact segments 19, 43 of different lengths are fixed in the craft and thus follow the gyroscope 11. When the contacts 17 cooperate with the segment 19 only to adjust one or other of the valves 22, compressed air from the supply 24a is directed to one or other of the jets 26 to precess the gyro at a slow rate. When the departure of the gyro and craft from the prescribed course is large, the contacts 17 also co-operate with the segment 43 to operate the central valve 41, whereupon the compressed air is directed to the more powerful precessing means 30-36. Specification 601,132 is referred to.

Abstract: 421,595. Alternating-current Induction motors ; condensers. HOWELL ELECTRIC MOTORS CO., Howell, Michigan, U.S.A. June 23, 1933, No. 17988. Convention date, June 25, 1932. [Class 35] [See also Group XXXVI] In an alternating-current motor having a number of stator windings a condenser connected in circuit with one of the windings is arranged around the axis of the rotor. As shown applied to a split-phase motor, the condenser 30 which is preferably of the electrolytic type and capable of withstanding high overloads for short periods, may comprise a single annular member or separate units forming a ring surrounding the motor shaft either within the housing 3 or on the outside of one of the end members 4, 5. The condenser is supported by rubber spacers 31 in such a way that the inner periphery is cooled by natural circulation of air under the action of the rotor. The stator laminations are square with rounded corners so that spaces are left between the straight edges and the cylindrical housing for the passage of conductors connecting the condenser with a centrifugal or electromagnetic switch at the other end of the machine. The centrifugal switch shown comprises two stationary slip rings 22 upon which bears a short-circuiting brush 25 carried by a pivoted arm 26 on the rotor biassed by a spring to bear on the slip rings. At a certain speed, the brush breaks contact with the slip rings thus cutting out the auxiliary stator winding and the series-connected condenser. The condenser is preferably of the type described in Specification 421,628, [Group XXXVI].

Filed: 1960-05-23
Abstract: 910,974. Stabilizing soil. ALCO CHEMICAL CORPORATION. May 23, 1960, No. 18073/60. Class 68 (1). Soil is stabilized by applying to the surface a composition consisting of a latex of natural rubber or a synthetic elastomer, and a " counter penetrant " consisting of a natural gum, methyl cellulose, hydroxyethyl ether of cellulose, an alkali metal salt of carboxy methyl cellulose, a poly-acrylate or poly-acrylamide. The " counter-penetrant " is absorbed by the soil rendering the latex unstable from which the elastomer separates and binds the soil particles. Pigments may be added to render the soil heat-absorbent or repellent, e.g. carbon black, or oxides of Pb, Sn, W, Ba to resistant atomic radiation effects. Fillers, e.g. clays or whiting may also be added together with antioxidants. The synthetic elastomers used instead of carbon latex include a range of polymers and copolymers including butadiene/styrene, vinyl acetate/acrylates, benzyl- and halogenated styrenes, poly-vinyl ethers and acrylonitriles, butyl rubber, and silicone rubbers. The composition preferably contains 2 to 4% of the elastomer, up to 0.5% of " counter-penetrant," and is applied at the rate of 0.25 to 5 ozs. of (dry) elastomers per square yard of surface.

Title: Improvements in variable speed gears for motor vehicles
IPC: F16H3/08
Filed: 1921-07-05
Abstract: 180,925. Raleigh Cycle Co., Ltd., and Wilkie, W. July 5, 1921. Variable-speed gearing for motor vehicles of the kind comprising gears C, E, B on a main shaft A constantly meshing with gears H, J, G on a lay-shaft F, the pair E, J being formed also as clutch members and being laterally movable together to change the speed, is modified to effect reversed driving by arranging that one gear G on the lay-shaft is disconnected from the other two on that shaft and is connected through a pair of idlers L, M with the middle gear E on the main shaft. The gear L is always in mesh with the gear G, and, in the form shown in Figs. 1 and 2, the reversed drive is produced when the pair E, J is slid to the extreme left into the plane of the fixed gear M. The drive is then through the train A, B, G, L, M, E, J, H, C. The next position to the right causes the loose gear H to be connected through a splined sleeve H<2> and the gear J to clutch dogs F<1> on the shaft F. The low forward speed is then through the train A, B, G, F, J, H, C. The next movement to the right brings the gear E into clutch engagement at C<2> with a long sleeve C<1> to which the driven gear C is secured, the gear J remaining in engagement with the dogs F<1>. The second speed is then through the train A, B, G, F, J, E, C'. The next movement causes the gear E to connect dogs B<2> on the shaft A to the clutch C<2> for a direct drive. In a modification shown in Figs. 3 and 4, the gear M is loose on its shaft K, meshes constantly with the gear E, and moves laterally with it. The reverse gear is then produced in the extreme right-hand position when the gear M is locked to the gear L by clutch teeth L', M<1>. In both forms, a kick starter may be applied to the end of a sleeve N on the lay-shaft.

Abstract: 541,542. Protective cut-out arrangements; thermal switches; resistances ; temperature responsive actuating elements. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 30, 1940. No. 18194. Convention date, Dec. 29, 1939. [Class 38 (v)] [Also in Group XXXVI] An over-voltage protective device, suitable for current transformers that have inadvertently been relieved of their burden, comprises a resistance unit of non-linear characteristic which decreases in resistance with increase of current or voltage, in the form of a pair of discs 19, 20 clamped on either side of a metal plate 21 by means of metal plates 22, 23 threaded to receive a bolt 24 which also fastens the whole to a support 18. Plate 21 is connected to one pole of the transformer secondary and a bolt 24 to the other pole, and an insulating sleeve 25 insulates the bolt from the discs 19, 20 and plate 21. whereby the discs are in parallel paths across the secondary. Plate 21 is grooved at 27 to receive a bi-metal strip so as to be responsive to the internal temperature of the unit. The strip is riveted at 42 and brazed or welded to the face of the groove. Its free end 29 co-operates with a pin 32 passing into the housing 31 of a snapaction switch adapted, when closed by excessive movement of the strip 28, to short-circuit the resistor. The switch comprises an E-shaped member, the outer limbs 33 of which are bowed apart from the inner limb 34, the outer ends of all the limbs being rigidly supported to the apparatus. When a small movement is imparted to limb 34 near its point of support, it snaps a movable contact on the yoke into engagement with a co-operating contact, and the contact opens again when the strip cools and removes the pressure. The distance between the housing 31 and strip is adjusted by mounting the housing on the outer arm 36 of a split shelf 30. By means of a pair of screws 39, 40 the distance between the arms 36, 37 is adjusted, the screw 39 passing freely through a hole in arm 37 and is threaded into arm 36, whereas screw 40 is threaded through arm 37 and carries a nut 41 bearing on arm 36. The discs 19, 20 are of a mixture of silicon carbide and carbon with a binder, or of silicon carbide with, for example, tungsten and molybdenum their surfaces being copper-sprayed.
