Abstract: 1,138,870. Fluorescent discharge lamps. PATRICK & DREW Ltd. 28 March, 1967 [30 March, 1966], No. 14085/66. Heading H1D. [Also in Division H2] A method of starting a gas discharge tube D without directly heating the electrodes thereof prior to starting, comprises installing the tube in a circuit which includes choke L connected in series with the tube, and a transformer T connected between an A.C. supply 5 and the series connected choke and tube, and arranging the transformer to supply an output voltage of 3 to 4 times the means operating potential of the tube, the choke causing the tube current to lag behind said output voltage, the current lag being such that, when the magnetic field in the choke collapses due to alternations in the supply voltage, a reverse voltage pulse is applied by the choke to the tube, and consecutive alternations of the supply voltage cause sequential increases in the amplitude of, and decreases in the rise times of, the reverse voltage pulses, which results in increasing the ion bombardment and thus progressive heating of the electrodes to give increasing electron emission, until a stage is reached when the rise time of said reverse voltage pulse is less than the deionization time of a gas contained by the tube, further ionization of the gas causing the electrodes to reach their operating temperature thereby allowing the tube to reach its operative discharge conditions, the choke then performing the function of a current limiting device for restricting the tube current to a normal operating value. A lamp with filamentary electrodes which can no longer be directly heated before starting because one or both of the filaments has become discontinuous can be started by the above method if the ends of the faulty filament are shorted together to provide a connection to the whole electrode.

Vibration-dampers of the one-way or differential type in which the working parts are oompletely enclosed, include a drum and radiallyexpanding shoes operated by toggle links from a central member which is automatically adjustable to take up wear. Two shoes 23, Figs. 2 and 3, are expanded into engagement with the drum 12, when the operating-arm 31 moves in one direction, by means of toggle members 22, the inner ends of which engage L-shaped parts 17, 20 adjustable radially in guides formed by projections 26 from the disc 14 connected to the operating-lever. The toggle-members 22 are pressed towards the engaging position by springs 27 and conical-ended pins 28, and their movement is limited in one direction by the parts 17, 20 and in the other by fibre or like pieces 30. The L-shaped parts 17, 20 abut a.t their inner ends against a conical element 18 which is held in position by a helical spring 45. A pull is also exerted upon the cone 18 by a screw 40 having a large head 41 bearing upon a disc 43 carried by the projections 26, this screw always tending to rotate under the action of the spiral spring 44. when wear takes place and the core 18 moves axially, the pressure of the head 41 of the screw on the disc 42 is relieved and the screw is rotated by the spiral spring 44 until the head 41 again engages the disc firmly and the cone 18 is thereby locked in its new position. In a modification the base 10 and the casing 12 are formed in one and three shoes are provided. For lubricating purposes, a separate compartment may be termed between the base and a disc 92, Fig. 11, oil being supplied thereto through an opening 94. This oil is supplied in limited quantities to the working parts through holes in the disc containing felt 93. The removable facing members on the shoes are held in dovetailed recesses and are deeply grooved diagonally and otherwise to avoid an excess of lubricant on the frictional faces.

Abstract: 312,788. Veloce, Ltd., Goodman, P. J., and Willis, H. J. May 17, 1928. Controlling variable-speed gearing.-In order to impart definite displacements to a gear control lever d upon a motor-cycle by the foot of the rider, repeated oscillations are given to a pedal-lever b, Fig. 1, which is connected to the lever d through ratchets. The lever b has a boss f, Fig. 4, with a pin t projecting between segmental strips s acted on by springs p. the effect being that no matter whether the lever b is moved up or down from neutral, the springs p return it to neutral with pin t in line with a stop n on a fixed bracket a. The boss f also carries in a different plane two oppositelyacting spring-pressed pawls e, Fig. 3, adapted to engage ratchet teeth h formed inside the annular boss i of gear lever d. The lever b has a ball end c which can be engaged either above or below by the rider's foot. When lever b is moved downwards from neutral, pawl e on the left engages and moves lever d downwards one step. Pawl e on the right is held inoperative by a cam k held by a projection m. Lever b is returned by springs p, and a second depression of lever b moves lever d a second definite step downwards, and so on. When lever b is moved upwards from neutral, the pawl e on the right acts to move lever d one definite step upwards, the pawl e on the left being held inoperative by the cam k. A second upward oscillation of the foot lever brings the lever d back to its original position, and so on.

Abstract: 739,379. Fluid-pressure servomotor-control systems. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-QUEST. June 10, 1952 [June 18, 1951; March 28, 1952], No. 14623/52. Class 135. [Also in Group XXXIII] A piloting device for controlling at least one of the control surfaces of an aircraft (see Group XXXIII) comprises a piloting member connected by a linkage including an irreversible servomotor to said control surface, the said piloting member being subjected on the one hand to an elastic device tending to return it to the mean position, and on the other hand to devices providing artificial reactions depending on at least one parameter of flight, so that the movement of said control surface is only determined by the movement imparted to said piloting member either by the pilot or by said artificial reactions against said elastic device. In the embodiment of Fig. 2, the control member 6 operates the servomotor 5 of an elevator 3 through rods 10 and a lever 28. Attached to one of the rods 10 is a lever 12 pivoted to the aircraft at 13 and connected by rod 19 to a member 20 slidable within the spring box 21. The position of member 20 on rod 19 is variable by rotating member 24, preferably by a handwheel adjacent the pilot, effecting trim. A double-acting spring box and a non-linear spring device are also described. Attached to lever 28 is a spring counterbalanced weight 30 adapted by its inertia to operate the servomotor 5 to counteract vertical accelerations. A control force is also provided by a piston 15 subject to the dynamic pitot head pressure. A damper 32 is also used. A preferred servomotor is shown in Fig. 6. The piston 67 is slidable in the casing 61 and is bored to receive the control rod 68, which has a narrow portion 68a between two conical portions 71, 72 adapted to operate ball valves 81, 82 and 83, 84. The casing is divided by partition 62 into two compartments 61a, 61b, communicating with high and low pressure fluid pipes. A bore in rod 64 connects compartment 61b through orifices 79, 77, to ball valve 83, 84, separated from compartment 61<SP>1</SP>a to the left of piston 67 by a seal 74 on the control rod. If the control rod moves to the left, valve 83, 84 is opened, putting compartment 61<SP>1</SP>a in communication with the low pressure compartment 61b through passage 85, orifices 77, 79 and bore 80, while the right-hand side of piston 67 is in contact with high pressure fluid, and the piston moves to the left until ball valve 83, 84 is closed. If the control rod moves to the right, both sides of the piston are at high pressure, but owing to rod 64, less surface of the right-hand side of the piston is exposed, so the piston moves to the right. Specification 629,006, [Group XXXIII], is referred to.

Abstract: 1,046,422. Photographic print-out processes. HONEYWELL Inc. April 11, 1963 [April 11,1962], No. 14647/63. Heading G2C. [Also in Division G1] In an oscillographic recorder wherein a spot of high intensity radiation produces a trace on a print-out paper or film 4 sensitive to such radiation, the trace being at first latent but becoming almost immediately visible upon subsequent exposure of the paper to all over radiation, the postrecording treatment for rendering the trace visible comprises the subjection of the paper to radiation of the wavelengths to which it is primarily responsive and to infra-red radiation or heat. Preferably the exposed paper is heated to a temperature as high as practical in the range 170‹F to 400‹F and while so heated it is exposed initially to low intensity light radiation and thereafter to high intensity radiation of substantially the same wavelengths as employed in producing the trace i.e. principally between 3000 A‹ and 4000 A‹. As shown, Fig. 2, a concentrated beam of high intensity ultra-violet radiation from a super-high pressure mercuryvapour lamp enclosed in a quartz envelope is reflected through a filter 12 and lens to the mirror 8 of each galvanometer in a group and thence to the paper 4 as it passes the recording plane between reels 2,3. The position of the high-energy spots may be observed through an amber-coloured window 15 and yellow light (5500 A‹ to 5800 A‹) from a lamp 16 facilitates observation of the traces as they appear. Heat from an electrically-heated platen 17 and visible and ultra-violet radiations from lamps 18, 19 mounted each side co-operate to latensify the latent images as the paper 4 is drawn downwardly. The preferred print-out paper is that disclosed in Specification 1, 018, 552.
