Title: Method of Bringing Two Non-Rotating Gearwheels Into Engagement With One Another to Permit Lapping of the Gearwheels and Device for Carrying Out the Method
IPC: B23F23/12
Filed: 1967-02-01
Abstract: 1,176,081. Grinding. OERLIKON-BUHRLE HOLDING Ltd. 1 Feb., 1967 [1 Feb., 1966], No. 4963/67. Heading B3D. A method of bringing a first non-rotating gearwheel 17 into engagement with a second non- rotating gear-wheel 18 for a lapping operation comprises pressing the first gear-wheel against the second and, in the event of mutual contact between the tips of the teeth, simultaneously turning the first gear-wheel in relation to the second until a tooth in one gear-wheel engages a gap in the other gear-wheel, the second gearwheel, during turning of the first, being braked against rotation. In apparatus for carrying out the method, the first gear-wheel 17 is mounted on a spindle 13 in a slide 11 movable along ways 12, the spindle being rotatable during the lapping operation by a belt drive 15 from a motor 16. The movement of the slide is effected by a fluid supplied to chambers 28, 29 on opposite sides of a piston 22 fixed to the bed of the machine, the supply being controlled by a valve 24 which is movable by a solenoid 25 and co-operates with a movable stop 39. The stop is carried by a slide 34 adjustable by a lead screw 37 and is movable relative to the slide 34 by a screw 40 driven by an inching motor 43. For effecting the turning of the first gear-wheel 17 during the movement into contact with the second gear-wheel if the tips of the teeth contact, a friction lining 51 on a pivoted lever 50 is pressed into contact with a pulley 76 on the spindle 13 carrying the belt-drive pulley 14 and the lever is rocked about a pivot 52 so as to impart rotation to the first gear sufficient for the teeth thereof to engage the gap between those of the second gear-wheel by fluid pressure applied to cylinders 58, 69. During the turning of the first gear-wheel 17 by the movement of lever 50, the second gear-wheel 18 is held against rotation by a pad 84 which is moved into contact with a drum 81 upon actuation of a solenoid 86. In operation, with the gears 17, 18 to be lapped fixed to their spindles, the solenoid 25 is energized to move valve 24 so the slide 71 is moved at a rapid speed to the right until the valve abuts stop 39 and is moved to stop movement of the slide. The movement of the valve actuates a limit switch to start the inching motor 43 and move the stop 39 to the right, the valve 24 and slide 11 following the movement of the stop. If the tips of the teeth of the gears engage, the movement of the slide is stopped, the valve above following the movement of the stop until a further limit switch is actuated to simultaneously energize solenoids 73 and 86, solenoid 73 moving a valve 74 so that fluid pressure is supplied to the cylinders 58, 69 to rock lever 50 and cause the friction lining to rotate the gear 17 a sufficient distance for its teeth to engage the gaps between the teeth in gear 18 and solenoid 86 applying the brake pad 84 to prevent rotation of gear 18.

Abstract: 891,849. Joint-making packing. SAURER Ltd., ADOLPH. Feb. 15, 1960 [April 6, 1959], No. 5272/60. Class 122 (3). [Also in Group XXVII] The joint between a cylinder head 6 and a cylinder casing 5 comprises a preferably metallic packing ring 1 which is wedged-shaped in the radial direction and so arranged that the high gas pressures in the cylinder 3 displace the packing ring radially outwards against the frictional forces operating on the packing ring, the angle of inclination between the surfaces against which it bears being such that, after the gas pressures cease to act, the restoring force acting on the ring is less than the limiting frictional force between the packing ring and the surfaces. The desired wedge shape may be provided by an inclined surface on either the cylinder head 6 or the cylinder casing 5, or on both these members, the packing ring being correspondingly shaped in these cases. Alternatively, the wedge-shaped surfaces 25, Fig. 10, of the ring may extend over only a portion of the bearing surface, be constituted by a plurality of stepped surfaces, or co-operate with a wedge-shaped ring 28, Fig. 11. The ring 1 may have a readily deformable region in order to effect a seal immediately after assembly and before the cylinder is used, this region being formed by grooving or convexing one surface of the ring or making the angle of the wedge slightly smaller than the angle in which it fits as shown in Fig. 5.

Abstract: 892,333. Nuclear fusion reactors. ENGLISH ELECTRIC CO. Ltd. Feb. 20, 1959 [Feb. 21, 1958], No 5794/58. Class 39(4) In a thermonuclear reactor comprising a toroidal discharge chamber and a transformer for inducing a discharge in the chamber, the turns of the transformer are closely wound around the chamber to lie substantially parallel with the plane of symmetry of the chamber whilst progressing uniformly by successive turns around the discharge axis of the chamber. In Fig. 1 the toroidal chamber is surrounded by an insulating former mode in two halves 10a, 10b on which is wound twenty turns connected in series between input and output conductors 11, 12. When energized this produces in effect the electrical equivalent of a uniformly distributed current passing along a hollow conductor of toroidal form, and this avoids one cause of instability in the discharge. In another arrangement, Fig. 6, five sets of turns are connected in parallel, each set comprising four turns in series. Thus turns 21-25 are connected to conductor 11 and turns 36-40 are connected to conductor 12; turns 21, 26, 31, 36 are connected in series, and similarly with the other four sets.

Title: Improved method of feeding liquid fuel to gas turbines and notably to jet turbine and propellor turbine engines
IPC: F02C7/22
Filed: 1950-03-09
Abstract: 696,758. Automatic control systems. SZYDLOWSKI, J. March 9, 1950 [March 19, 1949; Sept. 28, 1949], No. 5999/60. Class 38(iv) [Also in Groups XXVI, XXIX and XXXVII] A gas turbine engine fuel system comprising a valve which controls the fuel pump at an adjustable constant output pressure by opening or closing a main by-pass around the pump has the output pressure determined by the pressure between two restrictions in a second by-pass around the pump which also includes a valve responsive to engine combustion gas temperature. The combustion chambers 1a, Fig. 1, are supplied with fuel by a pump 3a through a hand-operated throttle valve 30 and a governor controlled valve 8a. The delivery pressure of the fuel is controlled by a valve 6a inserted in a main by-pass 7a around the pump. The valve 6a is attached to a diaphragm 43 which is loaded by a spring 31, the opposite end of which bears against a piston 32 sliding in a cylinder 33. The cylinder 33 forms part of a second by-pass which also includes two restrictions 34, 35 and a spring-loaded electrically-controlled valve 37a. When the temperature of the combustion gases exceed a selected temperature, the thermocouple 23a causes the relay 21a to be sufficiently energized to close the switch 19a. This in turn causes the winding 17a of the electrically-controlled valve 37 to be energized and the valve 37 to be opened. Fuel then flows through the second by-pass and causes a drop of pressure in the cylinder 33 which reduces the loading on the spring 31 with a consequent lowering of the controlled pressure in the pipe 5a. Less fuel is fed to the engine and the temperature of the combustion gases falls. The relay 21a is no longer sufficiently energized and the valve 37a is closed by the action of its spring. To allow a temporary increase of combustion gas temperature during take-off, a resistance 40 and a switch 41 is included in the circuit of the relay 21a and thermocouple 23a. By opening the switch the temperature at which the thermocouple operates the valve 37 is increased. The switch may be connected to throttle lever so that it may be opened only when the valve 30 is fully open. To prevent the time during which the switch 41 is open from lasting too long, the switch 41 may be a time switch as shown in Fig. 2. When it is desired to open the switch a lever 102 is moved counter-clockwise and this causes the rod 104 to be moved to the right and the switch 41 to be opened. The lever 103 is also moved and starts clockwork which rotates the wheel 101. The wheel 101 slowly raises the rod 104 and after a short time the rod is lifted off the cam on the lever 102 and is returned to the right by the spring 106. This causes the switch 41 to close and the lever 103 to return to its original position. Specifications 642,229, 686,908 and 693,217, [both in Group XXVI], are referred to. Reference has been directed by the Comptroller to Specification 638,494, [Group XXVI].

The rate of flow of the gas to the burner of a cigarette lighter utilizing butane or other gas fuel under pressure, e.g. liquefied gas, is determined by a body of metal such as sintered brass particles formed with fine interconnected pores which collectively conduct the gas through said body placed in the gas feed conduit to the burner. As shown a piece 31 of porous sintered metal capable, e.g. of excluding from its passages particles of about 0.0005 inches in diameter is placed in a recess 30 at the entrance end of a nipple 26 feeding the burner 11 the exit end of the nipple being closed by a cushion 27 on the end of a stem 15 when depressed by a spring-pressed ball in the lighter snuffer. A filter disc 23 is provided in the gas conduit to filter the gas supply to the piece 31. This piece may be punched out of a sheet of porous metal for deposition in the recess 30 and then secured in place by pressure of a tubular tool having a rounded annular upper end surface portion so as to press radially outwards the peripheral portions of the piece 31 to provide a force fit and to adjust the size of the fine passages in the central portions 40 to provide a flame of desired size which may be obtained, during adjustment, by a flow of gas, under the conditions prevailing during use of the lighter through the central bore of the tool.

Abstract: 463,896. Cathode-ray tubes; television receivers. FARNSWORTH, P. T. Feb. 28, 1936, No. 6076. [Classes 39 (i) and 40 (iii)] The screen 14 on which the image is reproduced by means of a cathode-ray beam A is arranged obliquely to the beam and the beam is kept in focus in the plane of the screen, during its magnetic deflection to scan the screen, by an auxiliary magnetic focusing field which is produced by the current passing through the deflecting coils and which thus varies with the angle of deflection. The alternating current passing through the deflecting coils 23 may be passed through coils 17, 18 which also carry direct current and produce a longitudinal focusing field, or the deflecting coils may be inclined to the axis of the cathoderay tube 1 so as to produce a varying component in the longitudinal focusing field. As shown in Fig. 1, the coils 17, 18 are of different diameters with adjacent ends approximately in the same plane. Between the coils 17, 18 are arranged the coils 23 and also a lens 27 for projecting an enlarged picture on to a screen 28, perpendicularly from the side of the screen 14 bombarded by the beam A. The screen 14 has a metal backing connected to the anode 6. The plane of deflection by the coils 23 is rotated through 90‹ by the longitudinal focusing field. The high-voltage anode conductor 12 is insulated from a surrounding metal shield ,13 and passes into a metal container 48 to engage a spring contact 50. In a modification, the undeflected cathode ray strikes the top edge of the screen 14 and the coils 23 carry pulsating current to deflect the ray downwards. The focus of the beam is then varied by the component of the deflecting field in the deflected direction of the ray instead of, or in addition to, by fluctuations in the current through the coils 17, 18, or through focusing coils separate from the coils 17, 18.
