Title: Improvements in change-speed gear for automobiles
IPC: F16H61/30
Filed: 1934-04-17
Abstract: 430,769. Variable-speed gearing. McKENZIE, S. B., 47, Grosvenor Street, Toronto, Canada. April 17, 1934, No. 11589. Convention date, July 13, 1933. [Class 80 (ii)] Shifter-forks 4, 5, Figs. 2 and 3, of a conventional motorvehicle change-speed gear are moved in either direction by axial movement of a single hydraulic plunger 10, which is turned, also by hydraulic means, to select the fork which is to be operated. The movements are all manually controlled by a single rotary distributing-valve 48, operated through a double endless Bowden-cable 55 by a preselective steering - column - lever 61, Fig. 1, and the change is rendered effective by depression of the main-clutch pedal 67, which supplies pressure oil by operating a plunger-pump 65. The hydraulic-plunger 10 carries a block 12, having a finger 13, moved into operative engagement with a notch 9 in either striker fork 4, 5 by one of two transverse hydraulic plungers 16, 17, Fig. 3, which serve to give the plunger 10 its selective turning movement. The plunger 10 is moved axially by pressure-oil supplied at either end and is moved to a central neutral position when a pair of additional plungers 41, 42, Fig. 2, slidable in its hollow interior 39 and connected to it with lost-motion at 44, are simultaneously moved outwardly by pressure-oil supplied to the interior 39. This supply is effected through a tube 29 on which the plunger 41 slides, the tube being secured to a screw-plug 26 which closes one end of the cylinder 11 in which slides the plunger 10. Pressure reaches either end of the plunger or its interior through sideducts 32, 35, 30, Fig. 6, in the cylinder 11. The rotary distributing-valve 48 is supplied with pressure-fluid through a housing-duct 24 to its centre 23, which is connected by radial ducts to selectively arranged outlets on its facing, which also has a shaped recess 49 shown dotted, communicating with an exhaust duct 68. The double endless Bowden cable 55 operating the valve, passes fully around both the valve 48 and an operating-pulley secured to the lever 61, the cable being positively secured to each of these elements. The valve 48 is located in gear positions by a spring- loaded ball 63, as are also the rails 2, 3 which slide with the striker-forks 4, 5. Non-return valves are arranged in both the supply and delivery pipes of the clutch-operated pump 65, which also has a main supply reservoir 71. The entire striking-mechanism is arranged in a cover-plate 1 which may replace those of existing change-speed gears.

Title: Improvements in or relating to focussing means of systems adapted to include a cathode-ray tube
IPC: H04N3/26
Filed: 1948-04-28
Abstract: 686,441. Cathode-ray tubes. PHILCO CORPORATION. April 28, 1948 [April 29, 1947], No. 11665/48. Class 39(i) [Also in Group XXXV and XL(b)] In a system adapted to include a cathode-ray tube, means are provided for developing a voltage the magnitude and polarity or phase of which is a function of the magnitude and sense of variation of tube focus. In Fig. 1 a cathode-ray tube 17 of a television receiver has a main focusing coil 18 the direct current through which is manually adjustable by a rheostat 19, and an auxiliary focusing coil 16 the direct current through which alternates between two values under the control of a sinewave oscillator 10 acting through a triode valve 14. The consequent alternation in focus, which is arranged to be imperceptible to the eye, nevertheless varies the secondary emission of the screen, and causes an alternating voltage to be picked up by a metallic electrode 20 and applied to an amplifier 26 tuned to the frequency of oscillator 10. As explained with reference to Fig. 2 (not shown) secondary emission is a minimum at optimum focus so that the phase sense of the alternating input to amplifier 26 is dependent on whether focus is above or below optimum. The output of amplifier 26 and of oscillator 10 are both applied to a phase comparator circuit including a transformer 11 and diodes 28, 29 which produces at the grid of valve 14 a potential of the appropriate polarity to restore deviations of focus from optimum by controlling the mean current through coil 16. Electrode 20 is associated with an area at the top of the screen in which the beam is normally blanked out for a few lines in the interval between frames but, in which, for the purposes of the focusing control, a few of these lines are unblanked by applying to the grid of the tube a pulse from a multivibrator 46 triggered by the frame synchronising pulse after delay in a circuit 45. The phosphor may be omtited from the screen material or the screen masked in this area. Electrode 20 which may be a metallic plate, mesh-like screen or transparent coating of gold, silver or aluminum inside or outside the tube face, may cover all or part of the tube face. A single focusing coil, a non-sinusoidal oscillator and applications to radar and to electrostatic focusing are referred to.

Title: Improvements in or relating to wheel brakes
IPC: F16D55/39
Filed: 1928-04-20
Abstract: 315,913. Ashworth, P. B., and Lister &. Co., Ltd., R. A. April 20, 1928. Disc.-In a braking-device for a wheel rotating on a fixed axle and provided with automatic means for intensifying the braking friction, an annular disc 20 rotatable with the wheel 10 has a brake surface 21 co-operating with an annular brake disc 22 floating on the axle 11, the two discs being pressed together by a brake-applying member 27 slidable axially but not rotatable on the axle 11, while either the member 27 or the brake disc 22 has an inclined intensifying cam 28 coacting with a corresponding incline 25 on the other member, and means are provided for moving the brake-applying member 27 axially and thereby initiating the self-intensifying action. In the construction shown the invention is applied to the wheel of a platform truck in which the axle 11 is supported by fixed forks 13 and the braking mechanism is duplicated with respect to each side of the wheel 10 so that two operating devices, e.g. a hand-operated means and a foot-operated means, may be employed, and both brakes brought simultaneously into action by either device. For this purpose, the two annular wheel discs 20 are connected by pins 19 slidable axially in holes in radial webs 16 connecting the rim 14 and hub 15. The axial movement of either of the brake-applying members 27 is effected by means of operating members 30 rotatably mounted on the axle 11 and provided with inclined surfaces 31 coacting with corresponding inclines 29 on the outer faces of the members 27. By forming the surfaces 25, 28, 29, 31 as double inclines, braking is effected whether the wheel is rotating forwards or backwards. Nuts 33 fixable in position by cross-pins 34 are provided to adjust the play of the brakeapplying members 27. In a modification the invention is applied to a vehicle road wheel mounted on a stub axle projecting to one side of a fixed supporting frame.
