Title: Improvements in or relating to change speed toothed gearing
Filed: 1928-08-24
Abstract: 316,790. Carling, W. T. Aug. 24, 1928. Facilitating changing speed. - Relates to variable-speed toothed gearing in which speed changes are effected by changing engagement of sliding gears or clutches and in which locking- means are provided for preventing inopportune engagement, such, for example, as described in Specifications 282,121, 294,301, and 307,631. An electrically-operated automatic fuel-reducing device is arranged to obviate the necessity of disengaging the main or engine clutch when changing speed, and means are provided to put the automatic fuel-reducing device out of action when a sliding gear or gear clutch is being disengaged. A switch arrangement shown in Figs. 1 and 4 is similar to one described with reference to Figs. 5 and 6 of Specification 315,967. A pivoted switch lever 1 is adapted to be rocked to the right by movement of the change-speed lever 5 so as to close a contact 2, which energizes the electromagnet which reduces the fuel supply. Upon a bracket 6 on the lever 5 is an insulating block 7 upon which are secured trip-striking plates 8, 9 staggered in different planes. A trip lever 3 carried by lever 1 can turn to the right against spring 3<c> but is kept by a shoulder 3<b> from turning to the left. When lever 5 is moved in the direction indicated in Fig. 4 to engage a sliding gear or gear clutch, the trip 3 is held rigid while riding over plate 8, so that switch lever 1 is tilted and the fuel-reducing device acts. On the return movement of lever 5, the trip 3 yields, and the lever 1 is not tilted, so that the fuel-reducing device is out of action. Similarly, trip lever 4, which can turn to the right, only coacts wth plate 9 when lever 5 is turned to the left to engage a different speed. An earthing switch is described for use with the electromagnetic fuel-reducing device described with reference to Figs. 3 and 4 of Specification 315,967 to prevent the charge from being exploded in an engine fitted with a magneto when the fuelreducing device acts. A switch is also described to the same effect in an engine with coil ignition. A switch is described for use where an engine clutch pedal is provided to put the fuel-reducing device right out of action when the clutch is open.

[Classes 39 (i) and 40 (iii)] In gas-filled cathode-ray tubes with the intensity of the beam modulated by television &c. signals, the effects of the beam modulation on the diameter of the spot on the screen struck by the ray are compensated by opposed effects on this diameter of beam-converging means controlled in rhythm with the modulation and comprising several ring-like or cylindrical electrodes of large aperture relatively to the beam cross-section, these electrodes being arranged inside the tube and being successively passed by the modulated beam before it reaches the deflecting plates. As shown, the beam is modulated by the Wehnelt cylinder 11 and passes through the anode 12 and the coaxial cylinders 15 .. 17 to the deflecting plates 13, 14. The cylinder 16 is positive relatively to the cylinder 15, 17 and the positive bias is supplemented by potentials corresponding to the modulation potentials so that the potential of the cylinder 16 increases as the ray intensity decreases. The electrodes 15 .. 17 may be coatings on the wall of the tube. The Specification as open to inspection under Sect. 91 comprises also modifications in which the electrodes 15 .. 17 are replaced by adjustable rings external to the envelope or by a coil the current through which is varied with the modulation of the ray. Choice of gas pressure so that the spot on the screen is of smallest diameter when the beam is near its maximum intensity, and making the beam converging electrodes by spraying zinc on to the wall of the tube, are referred to. This subjectmatter does not appear in the Specification as accepted.

Abstract: 852,026. Viscometers. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 13, 1957 [Aug. 13, 1956], No. 24677/56. Class 106 (2). [Also in Group XXIX] The apparatus comprises a torsional viscometer, and an air-actuated control system for controlling liquid additions to the liquid charge in the viscometer, the control system being operated by a member 10 movable in accordance with the viscosity of the charge, whereby the addition of liquid is controlled in accordance with the viscosity of the charge. As shown, the viscometer comprises a container 1 rotatable on a spindle 3 supported in bearings 4 by a case 5. A torsion spring 6 is attached to the spindle 3 and to the case 5 and can be adjusted on the spindle by means of a collar 7. An air motor 13 supplied with compressed air by a pipe 12 drives a stirrer 14 in the liquid and this tends to rotate the container 1 against the action of the spring 6, a pointer 8 co-operating with a scale 20 to give an indication of the viscosity. If the viscosity is too low, a vane 10 on the pointer 8 closes an air jet 11 and the resulting increase of pressure in pipe 16 opens a valve 17, allowing thinner to flow from a tank 19 to reduce the viscosity. This operation continues until the required viscosity is reached. In an alternative embodiment, the thinner is contained in a closed tank and pressure on the surface of the thinner when the jet 11 is closed, causes it to flow into the container 1.

Abstract: 209,036. Kirschner, F., and Hess, J. Dec. 20, 1922, [Convention date]. Gratings; wire fabrics.-Metal sieves, metal cloths, and other woven or plaited or like goods are formed of bright wire or metal strip and are coated galvanically, for example with a metal or alloy adapted to act as a solder. The goods are then heated whereby the wires &c. are soldered together at their points of crossing. Thus metallic fabric freed from grease and oxides is run from a coil through a high current galvanic tin bath, then a solder fluid or paste is applied, next the fabric is led through a known solder furnace with or without water cooling and finally the fabric is rolled up. The tin coating may be of sufficient weight to not only serve to solder together the crossing points of the wire &c., but also to reduce the size of the meshes of the finished article. The woven or plaited article may alternatively be made from wire already coated with metal capable of acting as a solder. A solder flux may be used comprising ammonium chloride, hydrochloric acid, ferric chloride and copper sulphate.
