IPC: F16D65/14
Filed: 1932-10-04
Abstract: 408,248. Linkwork; brakes; variablespeed gearing. WILSON, W. G., 23, Queen Anne's Gate. London. Oct. 4, 1932, No. 27517. [Classes 80 (ii) and 80 (iii).] Force exerted downwardly on a bus - bar m having a knife-edge-pivot connection at n with a frame e is transmitted to a spring a through a link k, pivoted at l to the bar and at j to a rod i, the rod i, a universal joint h, a lever f pivoted at g, a spherical bearing d<1> and a telescopic rod c, c<1> carrying end-plates b, b<1>. As the bar moves down, the pivot approaches the knifeedge n, thereby increasing the leverage on the rod i, so that the effort on a pedal, for example, connected to the bar is more or less constant in spite of the increasing pressure of the spring. The device is specially intended for application to brake bands and reaction bands of epicyclic gearing and ensures a full stroke of the pedal or lever connected to the bar m.

Title: Panoramic camera
IPC: G03B37/02
Filed: 1959-08-13
Abstract: 913,104. Panoramic cameras. MEOPTA PREROV, NARODNI PODNIK. Aug. 13, 1959 [Aug. 20, 1958], No. 27652/59. Class 98 (1). A panoramic camera with objective and sector type shutter in a rotatable cylinder has an arcuate housing the radius of which equals the focal length of the objective and two wing handles hinged on axes parallel to the swivel axis of the cylinder and the film spool axes. The panorama camera shown, comprises a housing 1, an objective 21 which is mounted in a cylinder 22, which is rotatably fixed to the camera housing, a dioptric viewfinder including a frame 14, diopter 15 and a mirror (not shown) arranged on the frame so that the reading of a clinometer 13 is visible in the viewfinder field. The frame 14 and diopter 15 are hinged so that they may be collapsed into a compact position behind the camera. The cylinder 22 may be rotated (so that light can pass through the tube 24 on to a film 29) by moving a release control 56 in direction shown which, through lever 52, 53, releases a rod 55 which in turn releases toothed (58) cylinder 22 which is then rotated by springs 33, 32. The camera is provided with two pivoted handles 35, 34. Handle 35 controls a device for advancing the film and a device for preventing double exposure. The former device comprises a ratchet wheel 36 which engages a second ratchet wheel 38 which, during film winding, is spring-urged against a wheel 40 on a film spool 26. Therefore rotation of handle 35 rotates (in one direction only) the ratchet wheel 36 and hence the film spool 26. The amount the film is turned on is determined by a counter 49 which is rotated by movement of film through rod 47 and tooth 48. When a stop 50 on this counter abuts one end of a lever 39 which is attached to wheel 38, this wheel is moved out of engagement with the wheel 38 and the film ceases to move. The second handle 32 may be used for rewinding the film or for winding up the swivelling device of cylinder 22. Specification 875,299 is referred to.

Title: Improvements in or relating to control mechanism for tractors
Inventor: MERRITT HENRY EDWARD
IPC: A01B63/111
Filed: 1957-09-03
Abstract: 896,860. Tractor power lift mechanisms. MASSEY-FERGUSON (UNITED KINGDOM) Ltd. Sept. 3, 1958 [Sept. 3, 1957], No. 27747/57. Class 79(1). A tractor has a power lift mechanism in which a hitch linkage (not shown) is raised, lowered or held stationary by control components operated by joint mechanical and manual means and respectively responsive to changes in the draft load and to changes in the position to which the hitch linkage is raised relative to the tractor; the control lever 36 operating both control components being movable selectively into either to a "draft control" range A-B or a "position control" range B-C. The control components are levers 38 and 39 which are pivoted at 51 and 84 respectively to the lever 36 which in its A-B range causes the lever 38, fulcrumed at 49, to operate a hydraulic valve 31 and in its B-C range the lever 39 to do the same instead. The valve 31 causes a piston 13 and cylinder 12 to turn an arm 15 to raise or lower the hitch linkage through lift arms (not shown) attached to a cross shaft 16. Changes in the draft load mechanically affect operation of the lever 38 by changing the position of its fulcrum 49 and changes in position of the hitch linkage affect the operation of the lever through a stud 82 pressed by a spring (Fig. 2, not shown) against a cam 81 on the shaft 16. The working of these features is more fully described in Specifications 896,858 and 896,859.

Title: Liquid fuel systems
Inventor: NICHOLS RICHARD ALLEN
IPC: B64D37/32
Filed: 1970-06-09
Abstract: 1,271,900. Inverting fuel tanks. PARKERHANNIFIN CORP. 9 June, 1970 [22 July, 1969], No. 27880/70. Heading A5A. The risk of explosion or fire in fuel tanks, particularly in aircraft, is reduced by injecting the liquid fuel into the tank vapour space through a spray in the fuelling port, and introducing an inert gas to fill the vapour -space and deoxygenate the fuel. The vapour space 2 of fuel tank I is supplied with N 2  via pipe 3 and fog nozzle 4. Valve 6 in pipe 3 is operable either manually, or mechanically when the aircraft is grounded or airborne by means of level sensing -float 9 or differential pressure sensing device 12 respectively. Level control valve 7 incorporates fuel outlet ports 8, preferably disposed above the maximum liquid level of the tank as controlled by float 9 which closes inlet port 10 at the predetermined level. Outlets 8 inject the fuel as a conical spray whereby the maximum surface area is presented to the nitrogen for removal of oxygen from the fuel. Outlet valve 11 vents the oxygen-containing N 2  from the vapour phase as it is displaced by the incoming fuel. When the aircraft is climbing and the fuel tank pressure exceeds ambient pressure by more than a predetermined value vent 11 opens. At cruising altitude and during descent 11 remains closed and N 2  is admitted through nozzle 4 to compensate for fuel use and increased ambient pressure. Consequently, air is excluded from tank 1 during normal operation, and the oxygen concentration in the vapour space is maintained at a safe level.

Patent GB-228636-A (GB)
Title: Improvements in, and relating to, oil lamps
IPC: F21V37/00
Filed: 1923-11-09
Abstract: 228,636. Bale, F. Nov. 9, 1923. Wick burners, annular, flat-flame. - An intermittent light is produced by means of an asbestos wick of such shape and size that it burns for a time after ignition and then extinguishes itself, being subsequently re-ignited from a continuous source of light such as an ordinary wick or gas jet. The intermittent wick may consist of a millboard, paper or woven asbestos wick and may rest on a cotton feeding wick, or it may be sandwiched between other wicks. The continuous wick may consist of a small cotton or asbestos wick or an asbestos strip resting on a cotton wick. Alternatively a compound asbestos may be employed, giving a continuous light at one side and an intermittent light at the other. A V or other shaped cutting, e.g. as shown in Fig. 3, provides a pointed end which serves as the continuous wick, or a small metal clip C', Fig. 7, permits of the continuous illumination of the adjacent portion of wick. Fig. 9 represents a burner having two compartments, one for an asbestos wick A which rests on a cotton wick C and provides the intermittent light, and the other for a small cotton wick B providing the continuous light. The wicks BC are regulated by separate spindles. The duration of light of the intermittent wick and the interval during which it is extinguished may be varied by altering the density and thickness of the wick, the angular cutting and the depth below the top of the burner of the feeding wicks when such are used. For igniting the burner, the intermittent wick may be ignited by means of an electric spark, itself igniting the continuous wick. To extinguish the burner a rubber ball may be employed, pressure on which forces a current of air up a tube at the side of the continuous wick to extinguish it when the intermittent wick is not alight. The burner cone is placed in position by means of three circumferential supports which rest on similar supports mounted on the reservoir and which are secured thereto by sliding catches.

Title: Improvements in or relating to gas-filled devices
IPC: H01K1/54
Filed: 1966-06-24
Abstract: 1,137,434. Electric incandescent lamps. PHILIFS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 June, 1966 [29 June, 1965], No. 28293/66. Heading H1F. The blackening of the bulb of an incandescent lamp is prevented by surrounding the filament with a grid, the temperature of which is higher than that of the envelope of the lamp, the temperature gradient between the grid and the grid is so low and the mesh size of the grid is so related to the distance from the filament, that the nuclei formed near the filament by atomic vaporization and the conglomerates grown from them are hampered in their movements by radiometer force, the voltage difference between the grid and the filament being zero or very small. The grid may be heated by radiation from the filament and may be connected in parallel with it. Examples are given of temperatures and dimensions. The arrangement may also be used in an absorption pump, to deposit metal on a given surface and to keep the remaining surface free from metal deposits. In a gas replenisher for nuclear physical apparatus, a nickel cup is enclosed in a bulb and surrounds a vaporization spiral of titanium. A molybdenum gauze is spaced above the cup and is heated during the vaporization of the titanium, the gauze serving to prevent escape of vapour but, when the bulb is afterwards filled with hydrogen isotopes, allowing ready access of these to the titanium soot deposited inside the cup.

Title: Bowl adjustment for crushers
IPC: B02C2/02
Filed: 1965-07-05
Abstract: 1,117,004. Gyratory crushers. BARBER-GREENE CO. 5 July, 1965 [16 March, 1965], No. 28330/65. Heading B2A. The gap 23, Fig. 1, between the crushing bowl liner 18 and the head 21 of a gyratory crusher is adjusted by rotating the bowl 15. The rotation is effected by means comprising an annular cap 30 welded and/or bolted to the upper annulus of the bowl, rotatable therewith and provided with an annular series of radiating projections 31, an actuator slidably and pivotally mounted on the crusher frame 10 and engageable with the projections 31, and means connected to the actuator for simultaneously reciprocating and swinging the same to rotate the bowl. As described, oppositely directed pawl assemblies 35, 36, Fig. 2 are slidably secured in guides 39, 40, which are pivotally mounted on a plate 44. Reciprocating movement of the pawls is effected by double-acting hydraulic rams 50, 51. The cylinder end 53, 54 of each of the rams is pivoted as at 55, 56 to an upright post or bracket 52. In operation, an hydraulic pump 71 is energised and the desired rotation of the bowl 15 selected by a switch 80. Current flows to solenoid 84, 85 to actuate valves 76, 77 and thus direct pressure fluid to a selected cylinder. When the ram is extended to a predetermined distance contacts open in the limit switches 86, 87 breaking current flow to the solenoids 84, 85 so that the piston rod is retracted, until the contacts in the limit switch again close and the cycle repeats. The limit switches are operated by trip pins carried by the pawl shafts. Check valves 108, 109 prevent feedback between the cylinders. A single actuator may alternatively be used with manual operation of the valves, and a manual hydraulic pump. Each pawl includes an adjustable friction drag device 120 . . 123 Fig. 4, which produces more positive movement of the pawl, and may also comprise a locking device 92, Fig. 5 to prevent rotation of the cap 30 during operation, and positively limit rotation of the cap while the pawl is on its return stroke. The pawl may be modified by providing the shaft with a slot and with guide pins to eliminate the slide guide.
