Filed: 1956-03-26
Abstract: 853,109. Liquid fuel burners. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. March 20, 1957 [March 26, 1956], No. 9211/57. Divided out of 853,110. Class 75(1). [Also in Group XII] In a gas turbine, the liquid fuel is applied to the surface of a rotating disc from which it is thrown off centrifugally as a liquid sheet, into the high velocity air stream from the compressor. The fuel is thus atomised and mixed with the air in the flame tube. A secondary air stream from the compressor passes between the flame tube and the turbine outer casing and part mixes with the combustion gases in the turbine and part flows back towards the flame tube inlet by a passage in the flame tube inner wall which is cooled thereby. The fuel spraying disc is slightly coned inwardly to cause the fuel to adhere by centrifugal force. As shown, the turbine 10, 12 is supplied from the flame tube 31 which receives air from the compressor, 6, 8 driven by 10, 12 through shaft 14. The fuel is led into 31 from hollow shaft 23 through ports 45, 47, to the downstream surface of the disc 24. The latter rotates with 14 and the ports are dimensioned so that the fuel is thrown from the disc periphery as a sheet into the airstream at 36. Turbulence is increased by the paddles 51. The air flow from 6, 8 is divided by the flametube outer wall 32 into two annular streams, one through duct 35 and the other into 31. The inlet to 31 is divided by fingers 36, which may be shaped to meter the air-flow. The outlet from 31 is a number of channels 56 formed by corrugations spaced apart circumferentially in 32 to provide alternating passages which discharge streams of hot gas and air. The inner wall 33 of 31 is cooled by air pumped by fan 61 from 56 through holes 62, into passage 60. Specification 853,108 also is referred to.

Abstract: 1,099,734. Constant force gas springs and hydropneumatic shock-absorbers. C. ARNOLD. March 4, 1965 [March 4, 1964; Nov. 2, 1964], No. 9276/65. Heading F2S. A constant force spring for counterbalancing, e.g. a suspended weight which is to be moved vertically comprises a cylinder 1 which receives, in a fluid-tight manner, a dip-rod 4 and which is filled partly with a liquid such as propane, isobutane, and partly with the vapour of this liquid, the vapour which is saturated always acting, with constant pressure, upon the lower end face of the diprod 4. The seal between the upper end of the cylinder 1 and the dip-rod 4 comprises a perforated sleeve 7 which, clamping packing rings 8 and 9, 10, is screwed at its ends into a cylinder end wall 3 and a guide ring 6, a flexible tube 11, drawn over the guide ring 6 and over an extension of the end wall 3, being filled with sealing liquid, and subjected exteriorly to the vapour pressure within the cylinder 1. A stop-ring 15 at the lower end of the dip-rod prevents a complete ejection of the rod. The gas is introduced into the cylinder 1 through the hollow dip-rod 4, closable at its upper end by a screw plug 18, and through a one-way valve at the base of the rod 4, a screw vent 17 being provided at the base of the cylinder 1. In a modification, Fig. 2, not shown, sealing liquid is accommodated in the annular space (32) between an end wall (23) of the cylinder (21) and a floating sealing piston (29) through which the dip-rod (26) extends, an inlet valve (34) being provided for the introduction of gas. In a further modification, Fig. 3, not shown, the constant pressure of the gas in the cylinder space (55) acts upon the expansible bellows (48) of an hydraulic ram comprising a dip-rod (50) which works in an oil-filled tube (46) welded in an end-plate (43) of the cylinder (41) and has openings (52) adjacent its open lower end. The cylinder (41) is clamped by bolts (44) between the end-plate (43) and a lower end-plate (42). Suitable heating and/or cooling apparatus may be provided for keeping the temperature constant, the apparatus being controlled by the pressure prevailing in the cylinder or, by a thermostat.

Abstract: 143,361. Smith, J. A. Manners-. April 2, 1919. Tea and like infusions, apparotus for making.-In apparatus for boiling water electrically at prearranged times the movements of a spring-actuated rotary switch are controlled by two stops, one of which is operated by a clock to allow the switch to close the heating circuit, and the other is operated bv movement of a kettle when the water boils, to allow the switch to open the circuit; an alarm is also provided. As shown in Figs. 1 and 3 the switch f, actuated by a spring f<1>, has a contact f<4> and a projection f<2>, the edge of which engages with a catch g, which is released by a clock j through a rod j<1> and allows the switch to turn. so that the contact f<4> bridges two fixed contacts f' to close the circuit of a heater in the kettle a. The switch is held in the closed position by the engagement of the projection f<2> with a second stop h mounted on arms c<2> carrying a platform c and a counterbalance weight e. The water, when boiling, siphons out through a tube b, and the consequent movement of the platform causes the catch h to release the switch, which then rotates in the same direction as before and opens the circuit. As shown in Fig. 4, at the second movement of the switch, the projection f<2> engages with and moves one end of a lever m<2> and releases the other end m, which is forked, from engagement with the bell hammer of an alarm; or an electric bell may be used. A stop k is then withdrawn bv hand from the projection f<2>, and allows a small movement of the switch and lever m so as to lock the bell hammer by means of the fork. An additional stop may be provided to prevent the spring f<1> exerting pressure on the hammer. The switch is reset by turning in the reverse direction, thereby rewinding the spring. The stops may be arranged as an escapement. In a modified arrangement the platform is arranged directly over the switch. An additional switch may be provided which is closed by movement of the counterweight. Specification 28116/19 is referred to.

Filed: 1960-03-16
Abstract: 943,622. Brake pedal mechanisms. CHICAGO FORGING & MANUFACTURING CO. March 16, 1960, No. 9364/60. Heading F2E. A brake control mechanism comprises a pivotally-mounted main control lever 3 having a cylindrical housing 30 concentric with the pivotal axis of the lever, and cam surfaces 31a, arranged within the cylindrical housing on a stationary part of the mechanism, in which rounded members, such as rollers or balls 32, are located between the cam surfaces and the inner cylindrical surface of the cylindrical housing so that, when the control lever is turned in a given direction about its pivotal axis, the relative movement thus produced between the cylindrical surface and the cam surfaces causes the rounded members to become wedged between those surfaces, and in which movable releasing means, such as the arm 10 having ball operating fingers 33, extends into the housing for the purpose of releasing the rounded members from their wedged positions, the releasing means having an arm 11 outside the housing which is connected to a pivotally mounted brake release lever 16. In order to apply the auxiliary or emergency brakes by the mechanism, the vehicle driver need only apply a smooth continuous pressure on the pedal 5. This results in rotation of arm 3 in a clockwise direction, as shown in the drawing, about pivot 2 and in so doing the emergency brake cable (not shown) secured within the aperture 7 is pulled and the brakes are applied. When the driver desires to release the brake, it is necessary only that he apply foot pressure again in the same direction to the pedal 18 of the release lever 16. The pressure causes rotation of the lever 16 in a clockwise direction about the pivot 15.

Abstract: 716,737. Variable resistors. FOX, P. X. July 14, 1953, [April 15, 1952.] No. 9375/52. Class 37. A variable resistor provided with a camcorrection device for obtaining the desired output law employs a centrally pivoted contact slipper which rolls along the resistance element under the influence of a cam track. In the example shown, the operating spindle 15 drives four quadrature spaced contact slippers 13 around a ring potentiometer winding 12. The latter is surrounded by a cam track 10 and each contact slipper 13 is pivoted at 17 at one end of a spring arm 14 and either has a single leg 16, Fig. 4, pressed by spring 16a into engagement with cam track 10, or is provided with two extremity legs as at 18 in Fig. 2. The legs 16 or 18 have turned up feet or rollers following the cam track i o and the undulations or gradients encountered cause the slippers 13 to rock about their pivots 17 and so advance or retard the point of contact with the resistance winding 12. The latter may be shaped or wound with sections having different gauges of wire. Also the resistance winding can be an arc of less than 360 degrees. The following modifications or requirements may be effected (a) the undersurface of a slipper may be gapped or cut away to give in effect a step in the output voltage (b) two or more cam tracks arranged to operate the same or different slippers (c) two or more cam tracks moved by a suitable drive (e.g. cam and/or gears) so that one output law may be set up for one slipper and another output law for another slipper (d) provision of an upper and lower face on the cam track so as to produce differential angles of rock on the slippers (e) cam track in the form of two or more adjustable segments so that phasing of the contacts in a plural contact device can be accomplished (f) the resistance winding and cam track may be rotated whilst the contact assembly is held stationary.

Abstract: 725,197. Endless track vehicles. INTERNATIONAL HARVESTER CO. April 7, 1953 [May 3, 1952], No. 9381/53. Class 79(1). [Also in Group XXIX] In an endless track assembly for a vehicle in which the idler wheel is carried in a bearing structure slidable on the track frame and connected by adjustable means to a captive spring assembly, the adjustable means setting the initial tension of the endless track and the spring assembly maintaining the tension and yielding on excessive tension, the adjustable means comprises a hydraulic ram structure, mechanical means locking the ram plunger relatively to the ram cylinder in the adjusted position. As shown the invention is applied to an endless track assembly comprising a hollow track frame 11 carrying on a fixed axis 14 a driving sprocket 12 on axes 19, rollers 18 and by means of brackets 22 rollers 21, round which and round the idler wheel 13 the endless track 17 is trained. The idler wheel 13 is carried in the bearing structure 16 longitudinally guided in the frame 11 and is connected to the captive spring assembly 28 housed in the frame. The spring assembly comprises sets of Bellville springs 48 held between a spring reaction plunger 43 and a rear end wall 49, the latter being adjustable by means of a rod 52 and nut 51. A cylinder 37 housing the springs carries at its front end a ring 38 shouldered at 41 against a partition 36 in the frame 11, a snap ring 42 in the ring 38 limiting forward movement of the plunger 43. The plunger 43 carries the hydraulic ram cylinder 32, the ram plunger 33 being connected by a thrust rod 26 to the bearing structure 16. The plunger 33 carries axially spaced serrations 33a, with which are adapted to co-operate serrations 34a on a plate 34 arranged within a slot in the cylinder 32 to provide the mechanical lock between the cylinder and plunger. The ends of the plate 34 and the walls of the cylinder receive bolts 58 to hold the serrations together and the cylinder carries a keeper plate 65 for the bolts. The serrations on the plate are out of symmetry along the axial length of the cylinder to enable the plate to be reversed, thus enabling the serrations to be engaged within a fraction of the pitch of the serrations. In operation when it is desired to tension the track the bolts 58 are slackened off to permit disengagement of the serrations, then hydraulic fluid is introduced into the cylinder from a grease gun engaging a threaded end of a passage 69 to tension the track and then the serrations are re-engaged to provide the mechanical lock, the threaded end of the passage 69 being normally closed by a plug 67. Specification 667,340 is referred to.
