Title: Improvements relating to agricultural implements attached to tractors
IPC: A01B35/14
Filed: 1936-02-05
Abstract: 471,515. Implements for working land. FERGUSON, H. G. Feb. 5, 1936, No. 3441. [Class 6 (i)] In a combined tractor and implement in which the implement is connected to the tractor by laterally spaced convergent linkage connections, so as to swing laterally about a point other than the actual connection between the implement and the tractor and closely follows the steering of the tractor, means are provided for limiting the lateral swinging and also the vertical movement of the implement when it is raised out of the ground. The implement shown in Fig. 2 is connected to the tractor by links 4, 5, with chains 6 connecting the lower links 4 to the rear of the tractor so as to be slack when the implement is in working position but taut when the implement is raised. The chains centralize the implement as it is raised and eliminate or restrict both vertical and lateral movement of the raised implement. In the arrangement shown in Fig. 3, the links 4 in the raised position engage with two cams 7 curved at their ends, or so shaped as to reduce or eliminate lateral freedom of movement without restricting vertical freedom. Vertical movement may be restricted by engagement of the links with the axle casing 8. Overturning of the tractor rearwardly may be prevented by the implement making contact with the ground and forcing the links 4 against the axle casing, or by the implement making contact directly with the tractor. Poweroperated mechanism for raising the implement actuates arms 10 connected to the lower links 4 by rods 11. Specifications 160,248, 253,566, and 320,084, [all in Class 6 (i)], are referred to. According to the Provisional Specification the crank arms 10 are connected to a very heavy cross shaft, and the upper link 5 controls the power-operated lifting device through variations in the draught required for the implement.

Title: Improvements in or relating to wind-motors
IPC: F03D7/02
Filed: 1951-02-13
Abstract: 720,591. Wind-motors. BUREAU D'ETUDES SCIENTIFIQUES ET TECHNIQUES. Feb. 13, 1951 [Feb. 13, 1950], No. 3446/51. Class 110 (3). [Also in Group XXIX] In a wind-motor, the blades are provided on their leading edges with spoilers, each in the form of a number of teeth, each tooth having a head which is rounded or is in the form of, for example, a truncated cone, the teeth preferably being connected together inside the blades. The spoilers are normally flush with the surface of the blade but can be protruded to cause aerodynamic stalling and thus prevent overspeeding. A spoiler comprises three teeth 91, Fig. 1, which project through holes 97 in the leading edge 95 of a wind-motor blade 96 and are carried by bars 93, 94, the latter being pivoted on parallel arms 110, 111. Arm 110 is connected by links 122, 124 to a cylinder 116 which is slidable on a hollow piston 117 pivoted at 120 to the blade 96. Compressed air is admitted at 128 and passes through the hollow piston 117 and a nozzle 129 into the cylinder 116. Counterweights 114, 115 ensure that the teeth are retracted when the wind-motor is stationary. The frusto-conical heads 92 of the teeth are then flush with the leading edge 95. The compressed air for operation of the spoilers can be supplied by a swashplate pump 17, Fig. 2, which discharges through valves 19, 19<SP>1</SP> into a succession of cylinders 14, 15, 16 which are interconnected by valves 20, 21. A valve 22 connects the cylinder 16 to atmosphere. The cylinders are thus changed to successively lower pressures. As the wind-motor speed increases, a centrifugal governor 31 moves a sliding valve 27 so that the air outlet pipes 36 are successively connected to the cylinders 14, 15 and 16 respectively. Ball detents 41 hold the valve 27 in the successive positions with the appropriate ports in alignment. The shaft 18 is rotated in the opposite direction to the windmotor hub 13. The spoilers are so adjusted that one set of spoilers is operated when the valve 27 is in its intermediate position and a further set is operated when the valve is in the position corresponding to the highest speed. The cylinders may be arranged concentrically around a central cylinder, and the valves 27 may be of the rotary type. Instead of being frusto-conical, the heads of the spoiler teeth may be rounded or spherical.

Title: Improvements in automatic lens covers for a binocular telescope
IPC: G02B7/12
Filed: 1960-02-01
Abstract: 884,213. Binoculars. D & D CO. Inc. Feb. 1, 1960 [Feb. 18, 1959], No. 3516/60. Class 97(1). A pair of binoculars comprises two housings for its lens systems which are slidably supported on a central bridge, protective lens covers being provided which are slidable in guides in the lens housings and mechanism for actuating the lens covers being located in the housings and in the central bridge so that movement of the housings on the bridge also moves the covers. In the embodiment shown in Fig. 1 the lenses cases 11, 12 are slidable on a bridge 10 which comprises four guides 40, two either end each of which comprises a plane part 43 and a toothed part 42 which engages a pinion 48 which is connected through a gear train 46, 55, 56 to a driving wheel, the teeth 59 of which engage the edge of a lens cover 21. The lens cover (Fig. 5) comprises slats 61, 62 of different lengths mounted in a web arranged so that teeth 29 engage the spaces between slats 61 and on rotation of wheel 58 draw the cover along a U-shaped guide rail 70. The two covers, for the eyepiece and objective respectively are separated in the open position by a plate 75 thereby preventing jamming. Louvre slats 61 have dimples 63 which position the cover on its rail and holds it away from other components of the lens casing. When the binoculars are opened by moving cases 11, 12 along bridge 10 teeth 42, 45 engage and cause the covers to be removed but when the minimum separation of the cases required for vision is reached the covers have been removed and the plane surface of pinion 48 slides on surface 43 of the guide to lock the covers in the open position. In the modification shown in Fig. 9 the covers each comprise two parts 121 (only one shown) each part is connected by a slot 149 therein to a pin 148 on a lever 135 pivoted at 137 said lever having a slot 144, 143 in which engages a pin 146 on the bridge 10. Part 144 of the slot is curved and part 143 is linear so that during the initial movement of cases 11, 12 along bridge 10 pin 146 moves in slot 144, rotates a lever 135 in direction of A and causes the lens cover to be moved along guide tracks away from the lens. When pin 146 slides in the now horizontal slot 143 no further movement of the lens cover is obtained.

Title: Method and apparatus for stabilizing the gain of a photomultiplier
IPC: G01T1/164
Filed: 1973-01-24
Abstract: 1418726 Stabilizing gain of photo-multiplier SCHLUMBERGER INLAND SERVICES INC 24 Jan 1973 [24 Jan 1972] 3602/73 Heading G1A The gain of a photo-multiplier is stabilized by measuring variations in the mean output current of the photo-multiplier and compensating said variations by modifying the illumination of the photocathode of the detector. Variations in gain, and thus mean current, may be due to temperature changes or sudden changes in illumination. In the arrangement described, a photo-emissive diode 13 is used to modify the illumination, being embedded in an epoxy resin disc-shaped light guide mounted between the scintillator 12 and the photocathode 11. Mean current is measured by an operational amplifier 22 having a capacitative feedback loop so as to act as an integrator and compared with a reference level 28 in further operational amplifier 26. Changes in intensity of diode 13 are in such a direction as to maintain the mean current constant. The signal relating to the radiation field under investigation is filtered by capacitor 20, to remove the D.C. background level.

Title: Improvements in or relating to self-regulating braking devices
IPC: B64C25/46
Filed: 1953-02-10
Abstract: 737,899. Fluid-pressure brakes. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Feb. 10, 1953 [May 10, 1952], No. 3727/53. Class 103 (1). In a brake regulating unit to prevent vehicle wheels skidding when braked, a casing is rotatable with the wheel to be braked and a flywheel mounted within the casing and coaxial therewith and restrained in an inoperative position by resilient means except when the rate of deceleration exceeds a predetermined upper value and wherein electrical contacts are operated by the flywheel overrunning the casing to release fluid-pressure from the brakes in the event of wheel skidding. A flywheel 12, carrying a projection 16 which operates in a slot in the casing 6, forms the accelerometermass which is coaxial with the axis X-X of the wheel R to be braked, but is free to rotate relatively thereto about the axis X-X in a limited arc, by reason of the projection 16 and the slot, and is supported in bearings 13, 14 within the rotatable casing 6, supported in bearings 4, 5, which is secured by pin 9 to the wheel R. Surrounding the casing 6 is a cylindrical housing 1, the axis of which is also X-X, which is clamped to journal F of the wheel R. The housing 1 is supported by bearings 4 and 5. The casing 6 carries, at one end, an insulating plate 7 on the outer face of which is carried two circular conductor rings 18, 19, the former being connected electrically to the metallic body of the casing 6, the latter being connected to a pin 22 by a carbon 23 passing through the insulating material 2, which is formed at one end of the housing 1, and connected to the pin 22 by a leaf spring. The circular ring 18 is similarly connected to a second pin 22 (not illustrated); both pins being housed in a plug socket formed in an extension 25 of the housing 1. Carried on the inner face of the insulating plate 7 is a metallic sector 21 and a, spring loaded sliding contact 26 secured to the flywheel 12. The flywheel is acted upon by a spiral spring 15 which yields at a predetermined deceleration to permit the electrical circuit to be so altered as to reduce or cut off the operation of the brake by virtue of the sliding contact 26 meeting the sector 21 and thus completing the circuit to excite an electro-magnetic valve which releases the brake valve. As soon as the sliding contact leaves the sector 21, the valve is closed again and the brake is applied. In the electrical circuit shown, the pins 22 are connected respectively at A to a source of electric current and at B are earthed to the casing 6. When the sliding contact 26 contacts sector 21 the circuit ACDFB is closed, the electromagnet E1 is excited and closes the circuit breaker I. The coil E2 is the live and actuates the electromagnetic valve which releases the brake valve.

IPC: H04N5/217
Filed: 1948-02-11
Abstract: 688,195. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 20, 1949 [Feb. 11, 1948], No. 3960/48. Class 40 (iii). In a television transmitting system employing a cathode-potential-stabilized type picture signal generating tube in which the scanning beam is suppressed during retrace periods so that the output from the tube during these periods has an average amplitude representative of picture black and in which interfering signals are picked up by the target electrode during line retrace periods, means are provided for re-inserting low-frequency and D.C. components, which may be lost in the system, with reference to the output signal developed by the target electrode during portions of the frame retrace periods not coinciding with the line retrace periods. In such a system due to capacitative or inductive coupling between the scanning coils and the signal plate the output developed by the tube during line retrace periods contains interfering signals of an oscillatory and symmetrical nature which tend to mark the true picture black signals but during the line scanning periods which occur during the frame retrace periods the tube output is truly representative of picture black and in accordance with the invention the output during these periods is employed as a reference signal in a D.C. reinserting network, the interfering signals being either completely eliminated or shifted above the black level and consequently out of the operating range of the reinserting network. Details of this embodiment are shown in Figs. 1 and 2 in which a pulse generator 18 supplies a blanking pulse at line frequency to a control electrode of a picture signal generating tube 1 and simultaneously supplies a pulse to an amplifier 17 which is arranged either to be blanked by these pulses or to have its operating characteristics so changed that the undesired spurious signals (20, Fig. 2) are shifted in the direction of picture white to leave a portion of desired signal such as 21 which is truly representative of picture black and with respect to which the network 22 ... 26 serves to reinsert the lowfrequency and D.C. components which may have been lost in A.C. coupling devices such as the condenser 16 and the amplifier 17. In a modification of the circuit of Fig. 1 instead of blanking the amplifier or employing pulses to shift the level of the spurious signals the signals supplied through condenser 23 are fed to an observing device which re-inserts the lost components and which is switched into operation at instants when the black signals are present (as described in Specification 458,585) or, alternatively, the method of re-insertion described in Specification 449,242 may be employed, Fig. 3 (not shown).
