Abstract: 902,120. De-burring machines. KEHR, G., and WICKMANN, C., [trading as KEHR & WICKMANN]. May 20, 1960 [May 29, 1959], No. 17795/60. Class 60. A machine for deburring or removing scale from workpieces 23b, particularly gearwheels, comprises a plurality of motordriven brush rolls or abrasive discs 22, the workpieces being rotatably mounted on and fed by intermittent conveying means, such as a rotatable table 15, conveyer, or slide, so that the workpieces are subjected to treatment by several successive brush rolls, the axes of which are set at an angle to those of the workpieces. The workpieces are mounted on pegs 23 carried by the conveyer 13 and they may be freely rotated by engagement with the brushes or secured to the pegs by expanding brushes or clamps, the pegs themselves then being driven through a gear-train, as shown in Fig. 5; when mounted freely, the workpieces are retained by a cover-plate 24 supported by the table. The steel or brass brush rolls 22, individually driven by motors 25, are adjustably mounted on fixed supports 20 so spaced around the periphery of the table 13 that one workpiece is located between each pair undergoing treatment by adjacent brushes. The angular adjustment of the brushes relative to the workpieces may be such as will cause the latter to rotate on their, support pegs 23 when freely mounted; the brush supports may be swung through 180 degrees about a vertical axis to set them at opposite angles to the workpieces. The rotatable table is intermittently movable through known driving means such as a crank 17, Fig. 5, having a pin engageable with a toothed wheel 17a at each revolution of the crank, a Maltese cross, or similar intermittent driving mechanism, or, alternatively, the driving motor may be controlled by a time-switch or known type of " programming " control system.

Title: Improvements in or relating to mechanical transmission systems
Inventor: ANTHONY ALASTAIR
IPC: B61C9/30
Filed: 1950-07-18
Abstract: 695,564. Variable speed gearing. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. July 30, 1951 [July 18, 1950], No. 17974/50. Class 80 (ii). [Also in Group XXXI] A single source of mechanical power is connected to each one of a number of driven elements by a slip coupling combined with an epicyclic gear train, the connection between each slip coupling and its epicyclic train being such as to provide two torque-transmitting paths in parallel, one of the paths being through the coupling and part of the gear train and the other path being through the gear train alone, so that the overall slip of the combination is less than the slip of the coupling. As applied to multi-axled rail locomotives, a single gas turbine 2, Fig. 1, drives a horizontal main shaft 3. The drive from the shaft 3 to each axle is taken through gear trains and couplings in oil-filled gearcases 4, and through vertical shafts 5. Each combined slip coupling and gear train unit 18, Fig. 2, is driven from the shaft 3 through a gear train 12 or reverse train 13, the driven shaft 11 of the unit being connected to the wheel axle 16 through bevel gears 15, shafts 5 and worm gears 17. In a modification the worm gears 17 are replaced by bevel gears, the shafts 5 being arranged in a vertical plane passing through the axle 16. As shown in Fig. 4 slip coupling half 32 and gear annulus' 33 are rigid with driving shaft 31, the carrier 34 for the planets 39 is fixed to the driven shaft 35 and the freely mounted sun gear 40 is fixed to the coupling half 37. Oil enters through a passage 41 to fill the gear casing. Torque can be transmitted through two paths in parallel, one path comprising the members 31, 33, 39, 38, 35 and the other the members 31, 32, 37, 40, 39, 34, 35. The interconnection between the slip coupling parts and the epicyclic gear parts may be modified. The hydraulic slip coupling may be replaced by a magnetic slip coupling. In a modification the turbine drives a shaft 63, Fig. 6, connected by a coupling 64 to a shaft 65. A gear 66 on the latter meshes a gear 68 driving a casing 76 which drives in parallel through combined slip clutch and gear units shafts 69, 69a leading to the vehicle axles. As shown the shaft 69 drives the axle 73 through gearing 70-75. Driving through reversing gearing having a layshaft 77 is effected upon operation of clutch members 64, 67. The layshaft 77 through gearing 78 drives a shaft 79 extending into the main body of the locomotive. An auxiliary power unit may drive the shaft 79 for starting purposes or for light running when it is not desired to use the main turbine.

Abstract: 548,108. Fuel tank altitude controls ; air pumps; valves. ROLLS-ROYCE, Ltd., DOREY, R. N., BRITISH THERMOSTAT CO., Ltd., and HURST, W. F. F. MARTIN-. Dec. 23, 1940, No. 18054. [Class 8 (i)] [Also in Groups XXVII and XXIX] An air pump A supplies air to replace fuel delivered from the tank or tanks F of an aircraft and has also a valve controlled outlet J to atmosphere. The valve comprises a disc 17 connected at its upper end to an evacuated spring-pressed metallic bellows 1 subject to atmospheric pressure through a pipe I, and at its lower end to a piston 20 working as a dashpot in a cylinder 22. At low altitudes, the valve 17 is opened by the atmospheric pressure on the bellows, and air flows to the atmospheric outlet J. At high altitudes the valve is closed and the pump supplies all its air to the tanks. Excess pressure in the inlet G then forces the cylinder 22 down, allowing escape of air. A vacuum relief valve 29 is provided on the ported flange of the cylinder 22, and opens if the pump fails at high altitudes, allowing air to flow back from the outlet passage J to the tanks. The main valve is set by turning a screw cap 6 on the casing, and the setting 10 held by a pin 36.

Patent GB-390126-A (GB)
Title: Improvements in processes for improving the properties of iron and steel alloys by precipitation hardening
Filed: 1931-06-22
Abstract: In a process for improving iron or steel alloys containing less than 0,4 per cent of carbon and susceptible to precipitation hardening, the alloys are cooled from a high temperature in a plurality of stages at different rates, the cooling in the first stage taking place sufficiently quickly to hold in solution the precipitation hardening element.  The cooling in the first stage consists in quenching in a molten metal or alloy of low melting point or in a molten salt bath or spraying with steam, water or other liquid.  The alloys may be tempered either by heating after quenching with or without intermediate cooling to room temperature or by leaving the alloys in the quenching liquid.  In an example, an alloy containing 3,5 per cent of titanium, 2 of silicon, and 0,15 of carbon is heated to 1150 DEG  C., quenched in molten lead to 400 DEG  C., cooled in air, and then tempered at 500 DEG  C.
