Title: Improvements in and relating to cathode-ray oscillographs
IPC: H03B13/00
Filed: 1935-03-26
Abstract: 457,554. Oscillographs. WATT, R. A. W., National Physical Laboratory, Teddington, Middlesex. March 26, 1935, No. 9312. [Class 37] [See also Group XL] A piezo-electric crystal in a cathode-ray tube or connected to an electrode of the tube is caused to oscillate by the electron jet or by other means and the mode and amplitude of this oscillation is influenced by means dependent on the oscillatory movement of the crystal under the action of the jet. The mode of oscillation of the crystal may be indicated by its glow. The jet may be oscillated by an oscillator connected to deflecting-plates or coils. The crystal 5 may be set into oscillation by electrodes 13, 14 connected to an oscillator 17. Voltages are set up in electrodes 7, 8 under the influence of the jet 2 on the crystal 5 and the consequent currents in the coil 12 coupled to the oscillator 17 influence the oscillation of the crystal, for example, by modifying the phase of the voltage applied to the electrodes 13, 14. In modifications, the voltages set up in the electrodes 7, 8 react on the deflection of the jet, as by connecting the electrodes 7, 8 directly or through an amplifier or network to a deflecting plate 3 of the tube, and the crystal is set into oscillation by the jet itself. The crystal may be coated with conducting material to form electrodes. Instead of the jet falling on the crystal, electrodes co-operating with the jet may be connected to electrodes on the crystal which may then be in a separate vacuum space. The intensity as well as the position of the electron jet may be varied ; modulation of the intensity produces modulation of the amplitude or frequency of the crystal oscillations. Control of the phase of the oscillations of the jet relatively to those of the crystal is used to vary the amplitude of oscillation of the crystal. The crystal may be oscillated at a frequency agreeing with one of its modes of oscillation, and the oscillation of the jet at a different frequency then changes the mode or frequency of oscillation of the crystal.

Title: Improvements in or relating to hard rubber varnishes
IPC: C09D119/00
Filed: 1925-04-08
Abstract: 243,966. Jackson, W. J. Mellersh-, (Mechanical Rubber Co.). April 8, 1925. Varnishes.-A varnish which dries to a hard rubber film and consisting of a solution of vulcanized rubber in an organic solvent, contains not less than 10 per cent of solid materials, at least 15 per cent of combined sulphur (calculated on the rubber content), and substantially no free sulphur, and has a viscosity at 50‹ C. of 1-10 Engler. The solution may be obtained by dissolving raw or vulcanized rubber in a highboiling organic solvent (such as solvent naptha, xylene, naphthalene, &c.), adding sufficient sulphur to produce a vulcanized rubber containing 15-32 per cent of sulphur, with or without the addition of accelerators, and heating the mixture, e.g. to 160-170‹ until vulcanization to the desired extent has occurred. The greater part of the solvent may subsequently be distilled off or replaced by another solvent. The solutions may be coloured with dyes or pigments.

Title: Method and apparatus for producing beadlets
IPC: A23K1/00
Filed: 1956-03-28
Abstract: 814,259. Producing solid drops from molten materials. EASTMAN KODAK CO. March 28, 1956 [April 15, 1955], No. 9641/56. Class 87(2). Uniformly-sized beadlets of a normally solid, fusible, organic material are produced by extruding the material under a pressure between 50 and 250 lb. per square inch, substantially free of unfused material, through capillary bores between 0À001 and 0À015 inches diameter into a gaseous cooling medium in liquid streams of substantially uniform cross-section. The molten material is pumped from a heated tank 10 to extrusion heads 19, each of which comprises a housing 32 with an outlet wall comprising a die plate 34 held in place by a cap 36 with a bayonet coupling. The inlet includes filtering media 40, e.g. cotton wadding, retained by a fine mesh screen 39. Drawn stainless steel capillary tubes form the die orifices 42 which may be of various diameters. As the extruded streams of material descend in a tubular structure 23 they become beadlets, which encounter a stream of cooling gas (air, nigtroen, or carbon dioxide) blown upwards through louvres 27 ; or alternatively in the same direction as the stream. The beadlets are collected through a duct 29 with a gate 30. On its way to the extrusion head the material, impelled by a pump 16, passes through a strainer and filter 15, 18 and regulating valve 21, 22. Typical materials are mineral and vegetable waxes, solid fatty materials e.g. lard, tallow and esters of glycerine, to which may be added stabilizers or antioxidants e.g. butylated hydroxy anisole &c. Numerical examples are given of the formation of beadlets from a mineral microcrystalline wax and from a monoester of glycerine.

Title: Ground anchors
IPC: E02D5/80
Filed: 1928-03-30
Abstract: 293,014. Matthews Corporation, W. N., (Assignees of Birkenmaier, T.). June 30, 1927, [Convention date]. Ground anchors comprise a rod 3 to the upper end of which a guy wire &c. to be anchored is attached and to the lower end of which a camming plate 19 having a rim 18 is secured. The rod passes freely through a collar 5 on which flukes 17 are pivoted. On the convex side of each fluke a correspondingly shaped rib 29 is formed for engagement with the rim of the camming plate, so that on the collar being hit from above by a tool 39 the flukes are forced outwardly into the ground and are locked in extended position by the engagement of a recess 33 over the rim of the camming plate. The flukes may be held closed during insertion in the hole 1 by tying twine &c. 37 around them. In a modification, Fig. 4, the flukes are formed with projections 61 which, in the closed position, engage in corresponding recesses in the adjacent flukes. In this form the pivot pins 65 are of sufficient length to prevent unintentional movement of the adjacent pivot pins so that only one retaining split pin 71 is required for the whole series of pivot pins.

Title: Improvements relating to weighing and weight recording apparatus
IPC: G01G23/37
Filed: 1961-03-17
Abstract: 900,993. Weighing apparatus. AVERY Ltd., W. & T. (Tacho-Schnellwaagenfabrik G.m.b.H.). March 17, 1961, No. 9742/61. Class 143. In weighing apparatus of the kind in which peripherally stepped graduated measuring wheels, corresponding one with each of decade or other orders of measuring values, are driven from the weighing apparatus so as to be set angularly in accordance with the magnitude of a weighment, and in which feelers are brought into contact with the adjusted measuring wheels so as to translate mechanically the position o the wheels to recording members, the feelers 1 are coupled, at 2, to pivotally mounted contact arms 3 sweeping over contact banks 5 connected in circuit with remote electrical recording or indicating mechanism, rotating switching means 16 being provided for imparting impulses through the selected contacts to the remote mechanism in accordance with the magnitude of a weighment. One end of each feeler 1 is also coupled, at 7, to a lever 8 which is rotatable about a shaft 10. Rotatable about the same shaft 10 are two arms 11 which are connected at their upper ends by an axle 12. Initially, the arms 11 are pressed back by a cam 14 (the position shown in Fig. 1) and the axles 12 thus cause the levers 8 to hold the feelers out of contact with the measuring wheels against the force of springs 19. When the measuring wheels have arrived at their weight indicative position, the shaft 13 which carries the cam 14 is rotated by a handle (not shown) so that the axles 12 allow the levers 8 and the feelers 1 to move towards the measuring wheels. The contact arms 3 are thereby displaced to assume angular positions according to the positions of the measuring wheels. When all the contact arms 3 are in position the handle also causes a motor to rotate a shaft 15, thus causing cam lobes 16 to close contacts 17 in succession, and so imparting the required impulses through the selected contacts 5.

[Class 37] The moving element of a tuning indicator for a wireless receiver carries a member 6 moved by rack-and-pinion means relatively to the moving element so as to indicate small adjustments. A carriage 1 carrying a pointer 2 slides along a straight bar 3 so as to carry the pointer 2 over a scale 4. A pinion 5, Fig. 1, attached to a disc 6 is mounted on a spindle 7 carried by the carriage 1 so that the pinion 5 meshes with a rack 8. The edge of the disc 6 is calibrated and is adjacent to a mark 9 on the carriage 1. In a modification, Fig. 2, backlash is eliminated by means of a thread, thin string, piano wire, &c. 14 attached to and wound on to the spindle 7 carrying the disc 6, the free end being held under tension by a spring 15. The spindle 7 is driven through gearing 16 by means of a spur-wheel 17 engaging a perforated strip 18. The rate of revolution of the spindle 7 and its circumference are such that the rate of winding or unwinding of the thread 14 is equal to the rate of travel of the carriage 1, so as to maintain a constant tension on the thread.
