IPC: B61F17/08
Filed: 1951-02-17
Abstract: 715,025. Lubricating. MILLER, G. D. Feb. 17, 1951, No. 3912/51. Class 12(3) A lubricating device, for use for example in suspension bearings for electric traction motors of diesel locomotives, includes a cover plate for an axle cap, and a journal lubricator resiliently carried by the cover plate whereby both the cover plate and the lubricator may be installed or removed by the same operation. As shown, a motor suspension bearing 10 provided with an apertured liner 11 for a wheeled axle 12 is associated with an axle cap 13 provided with an oil reservoir 15. The cap 13 has a cover plate 36 to which is attached a mounting plate 38 for a pad lubricator. The plate has a V-shaped base 25 the flanges of which receive a pivot pin 27 for levers 28 which also carry a pivot rod 22 for a group of felts, and comprising a curved pad portion 17 for engaging the axle 12 and a wick portion 19 extending into the oil in the reservoir 15. Each pad is partly gripped by a U-shaped holder 20. Pivotal movement of the pads about the rod 22 is limited by the provision of slots in the top of the pads and holders to receive a limiting rod 24 connecting the levers 28. The pads are yieldingly pressed against the axle 12 by means of torsion springs 29, which have intermediate portions 30 resting against the base 25, end portions hooked about a rod 32, and the main portions coiled around the pivot pin 27. In a modification the torsion springs are replaced by coil springs located in cylindrical barrels secured'to the mounting plate 38. Specification 668,189 is referred to.

Title: Improvements in or relating to stabilising devices
IPC: G01C9/12
Filed: 1949-02-14
Abstract: 692,342. Clinometers. SUREL, H. J. Feb. 14, 1949, No. 4031/49. Class 97 (ii). A clinometer comprises a pendulum arm 27 provided with a balance weight 28 and mounted by a roller or ball bearing 26 in a boss 23 in the closing plate 24 of casing 10. An arm 16 is secured to a spindle 14 rotatably and slidably mounted in a bushing 15 in the opposite wall of the casing. The arm 16 carries an arm 38 passing through apertures in the arm 27 and the wall 24 whereby rotational movement of the arm 27 is communicated to the arm 16. The arm 16 is provided with a roller 17 engaging a helicoidal groove 13 in a sleeve 12 fixed to the casing. The rotational movement of the arm 16 is therefore accompanied by axial movement which is communicated to a spindle 19 rotatably mounted in a boss on the arm and also mounted in a bearing 22 in the plate 24. The spindle 19 is provided with a helicoidal groove 20 of the same pitch and sense as the groove 13 but many times smaller, the groove 20 being engaged by a stud 21 projecting from the sleeve 22; by this means the angular movement of the spindle 19 corresponds with that of the arm 27. The arm 38 passes additionally through a plate 30 mounted by ball or roller bearings 29 on the boss 23. The plate 30 carries an arm 31 also supported by a roller 33 on a platform 34 provided on the spindle 19; the arm 31 terminates in an index 32 co-operating with a sector-shaped scale plate 35 which is viewed through a window 37 in a housing 36. The apertures in the arm 27 and plate 30 are flanked by anti-friction rollers 39 to permit free sliding movement of the tongue 38. The arrangement is stated to stabilize the pendulous system against oscillation and to be applicable to the stabilization of pendulous systems other than clinometers.

Abstract: 846,977. Nuclear reactors. BABCOCK & WILCOX Ltd. Feb. 6, 1959 [Feb. 7, 1958], No. 4152/58. Class 39(4). In a gas-cooled, graphite moderated nuclear reactor, the pressure vessel inner surface is thermally insulated. A hollow stainless steel base, having a cellular structure is bolted in sections to the vessel inner surface, each cell of the case being filled with graphite particles. Vent holes are provided in the case which permit gas pressure equalisation inside and outside the case but which prevent the escape of the graphite particles. As shown, the upper part of the pressure vessel 10, excluding the control duct 11, is provided with the thermal shields 16A, 16B, 16C, 16D, 23, 25, 40, 41, 43, 50, 51.

Title: Balance

Abstract: 1,260,745. Photo-electric indicating apparatus; weighing electrically. STAMICARBON N. V. Jan.24, 1969 [Jan.25, 1968], No.4173/69. Headings G1A, G1N, G1W. In a torsion balance which operates on the principle that out-of-balance of the balance arm is sensed (e.g. by photo-electric system) and a current supplied to a measuring coil to cause the arm to be restored to equilibrium, in order to render the balance more sensitive, the stabilizing effect of recovery forces due to twist in the torsion member during out-of-balance, is neutralized by an unstablilizing magnetic force provided by a coil mounted on the arm and a fixed permanent magnet. In the arrangement of Fig. 1, the balance arm 1 is mounted on torsion bar 2, and deviation from the zero position is sensed by photo-electric system 7, 8. Sufficient current from device 6 is then applied to measuring coil 14 within casing 5 to restore equilibrium, this current being a measure of the load. The construction of the measuring coil arrangement 5 is detailed in Figs. 6-12 (not shown). Also integrated with the device 5 is the coil for introducing an unstabilizing magnetic force on the arm to compensate for the above-mentioned recovery forces of the torsion bar 2. Various other coil arrangements are described, for providing this unstabilizing force, in which the coil is attached to one of the balance arm, and is associated with variously-shaped permanent magnets, Figs.3-6 (not shown).

Title: Improvements in speed governors for use with gas turbines
Inventor: TYLER STANLEY RALPH
IPC: F02C9/28
Filed: 1956-02-13
Abstract: 817,395. Gas-turbine plant. DOWTY FUEL SYSTEMS Ltd. Feb. 11, 1957 [Feb. 13, 1956], No. 4467/56. Class 110 (3). [Also in Group XXIX] A speed governor for a gas-turbine engine which acts to maintain a selected engine speed by controlling fuel flow to the engine has means for providing a stabilizing signal which varies with fuel flow and acts in conjunction with the speed governor on fuel flow to prevent unstable governing. As shown, an engine-driven centrifugal governor 7 is opposed by an adjustable spring 24 and acts on a lever 36 pivoted at 37 and carrying a half-ball valve 38 which coacts with an orifice 39 controlling the escape of fuel from a chamber above a piston 43 which operates a fuel by-pass valve 44, the chamber below the piston 43 being connected to the delivery side of a fuel pump 46 and the chambers on each side of the piston 43 being interconnected through a restriction 51. The arrangement is such that an increase of engine speed causes the orifice 39 to be opened to reduce the pressure above the piston 43 to cause the latter to increase the amount of fuel being by-passed. Fuel flowing from the pump 46 to the engine passes through chambers 57, 58 between which is an orifice 55 controlled by a valve member 54 connected to a servopiston 56. The pressures in the chambers 57, 58 are communicated through passages 57a and 58a to pressure pads 59, 61 which are interconnected by a member 62 bearing against an extension of the lever 36 above the pivot 37 whereby a change of fuel flow through the orifice 55 consequent upon an action of the governor gives rise to a stabilizing feed-back on to the lever 36. To maintain the speed setting of the governor substantially constant with variation in ambient pressure, or to provide a desired droop, the orifice 55 is adjusted in accordance with ambient pressure by the servo-piston 56 which is controlled by a halfball valve 71 carried by a lever 64 pivoted at 69 and acted upon by an evacuated bellows 75 and a bellows 74 subject internally to jet pipe pressure, this pressure varying with ambient pressure. Since the jet pipe pressure also varies with engine speed the arrangement provides for a progressive change in governor speed datum thereby bringing about an anticipation of the final speed selection. The lever 64 has an extension between which and the end of the valve member 54 extends a spring 66. Also acting on the end of the lever 64 is another spring 67 whilst a third spring 68 reacts between the end of the valve member 54 and the lever 36. The bellows assembly 74, 75 is adjustable towards or away from the pivot 69 by means of a screwed rod 79 having a squared end 81. In a modification increased speed of response without instability is obtained by interposing a servo relay between the governor 7 and the lever 36. It is stated that an hydraulic governor embodying a centrifuge may be employed instead of a mechanical governor.
