Title: Hydraulic arrangement for feeding the slides of machine tools and the like
IPC: F15B21/045
Filed: 1957-01-07
Abstract: 852,111. Machine-tool details. SALOME, V., and SALOME, C. Jan. 7, 1957 [Jan. 26, 1956], No. 551/57. Class 83 (3). [Also in Group XXIX] An hydraulic arrangement for feeding the slides of machine-tools &c., comprises automatic regulating - means compensating for changes in the resistance-to-movement of the slide, and also a thermal regulator compensating for changes in viscosity of the drive-fluid. A lathe-carriage 1 carrying a tool 2 is formed with a cylinder 3 co-operating with a piston 4, the rod of which is secured by a bracket 5 to the machine-frame. A device 6 for maintaining a constant feed when the resistance to the tool varies, receives exhaust-fluid from the cylinderspace 27 through the line 25. On a reduction in the resistance to the tool-feed, the carriage tends to increase in speed, and fluid expelled from the space 27 increases and pressure increases on a free piston 12 to overcome the thrust of a spring 13, and thus increase the flow through a slot 16 in a differential piston 11, 11a. The feedpressure in the line 17 is adjusted by altering the compression of the spring 13 by the screw 14. A second line from the exhaust space 27 leads to a regulator 7 for automatically overcoming changes of viscosity in the working fluid. A bellows 40, in contact with this fluid, presses against the underside of a sleeve-valve 29, which in moving adjusts the size of a throttling orifice 38 formed in the top of an adjustable pistonvalve 35-37.

Title: Composite grinding wheel and method of making the same
IPC: B24D18/00
Filed: 1938-01-08
Abstract: 498,951. Grinding-wheels; moulding. NORTON GRINDING WHEEL CO., Ltd. Jan. 8, 1938, No. 653. Convention date, Jan. 12, 1937. [Class 60] [Also in Group V] A composite abrasive wheel is made by assembling a central support 30, Fig. 3, between a pair of plates 42, 43 arranged within rings 35, 36 slidable in a mould band 34. A predetermined quantity of a mixture of abrasive grains and a heat-settable material, such as a resinoid or vulcanizable compound, is placed around the periphery of the support between the rings, the adjacent faces of the rings being cut away at 39, 40 to give the required shape to the abrasive rim to be formed on the support. Pressure is applied to the ring 35 until the parts 37, 38 of the adjacent faces of the rings contact, thus forming the rim on the support. The lower faces of the plate 43 and ring 36 are now flush with the lower face of the band 34 and the upper faces of the plate 42 and ring 35 are flush with the top face of the band 34, so that no pressure is applied to the support 30. Heat is then applied to set the rim. The plate 43 may be integral with the ring 36, as in Fig. 2, wherein the parts are shaped to form a V-shaped rim 24 projecting from an annular groove in the support. The latter may be formed of pre-moulded resinoid or vulcanizable rubber material which is heated to set it either before or after the compression of the rim thereon ; in the latter case, the original width of the support is slightly oversize so that, during the pressing operation, it is compressed to size and its plastic flow assists in securing the rim thereto. Alternatively, the support may be of wood or other suitable material.

Title: Methods of constructing internal combustion engines suitable for manufacture as either two or four cycle types
IPC: F02B69/06
Filed: 1931-01-08
Abstract: 370,955. Frames. TANGYES, Ltd., Cornwall Works, and JACKSON, P., Roseville, Turville Road, both in Birmingham Jan. 8, 1931, No. 671. [Class 7 (ii).] In a heavy oil engine the cylinder block or main frame is formed with passages, ports, and facings so that either a two-stroke or a fourstroke cycle engine may be built. The frame 1 is formed with a chamber 11 with which communicate passages 19, 15 ; it has also facings for the openings 12, 13, 14 to the chamber and for a fan. When a four-stroke engine is desired, the facing 2 for the fan is closed, a liner 3 is inserted in the frame closing the passages 19 and a head 4 is fitted to cover the cylinders this head forming with the passages 15 an inlet manifold drawing air from the chamber 11. An overhead cam shaft 7 works both inlet and exhaust valves. If a two-stroke engine is to be built, the inlets 12, 14 are blanked, a different head is fitted closing the passages 15, a new liner is supplied with ports to register with the passages 19 and a fan supplies air to the chamber 11 ; the overhead cam shaft suit. ably driven works the exhaust valves. The same head may be used in which case the inlet valve openings and the passages 15 have to be blanked. In another arrangement the frame is constructed to provide a two-stroke engine with terminal exhaust ports, each liner then having either terminal air inlet ports or being arrangod with an inlet valve in the head. When a four-stroke engine is to be built a different liner has to be used with a cylinder head which has the usual inlet or exhaust valves controlled by a cam shaft ; the exhaust passages in the frame are stopped off and the fan used in twostroke working is dispensed with. As a fourstroke engine the valve tappet rods pass through the air admission chamber.

Title: Improvements in radiation detectors
Inventor: BROWN ALFRED ROBERT
IPC: G08B17/12
Filed: 1964-01-08
Abstract: 1,096,992. Flame and like radiation, detection and monitoring. GRAVINER MANUFACTURING CO. Ltd. and WILKINSON SWORD Ltd. Jan. 8, 1965 [Jan. 8, 1964], No. 807/64. Heading G1A. The invention relates to radiation detection systems particularly for use in the monitoring or detection of ultraviolet from flames. According to the invention a detector is provided having electrodes between which an arc discharge can be initiated by incident radiation. This is connected to an A. C. supply and means are provided performing a controlling, warning or indicating function in response to a change in radiation intensity. In a first embodiment transformer TR1 applies 600 V A. C. across detector PC1 and R1 and R2 in series. A capacitor C4 is in parallel with PC1. Above the instantaneous voltage at which the detector breaks down in the presence of radiation an oscillating voltage appears across PC1 due to the repeated charge and discharge of C4. The voltage developed across R2 is applied to a discriminator comprising a multi-vibrator T1, T2 and negative half cycles cause T2 to conduct and energize relay RL resulting in illumination of warning lamp L1. Capacitor C2 holds the relay during the positive half cycles. It is stated that a short circuit in the detector resulting in the application of the transformer secondary waveform to R1 and R2 results in a signal of lower peak amplitude being applied to the discriminator circuit, such lower signal not being capable of operating the relay. Other embodiments rely on the breakdown of the detector to apply an A. C. voltage to a bridge rectifier energizing a lamp control relay. An integrating circuit introducing a time delay may be incorporated to reduce the effect of spurious signals. In the circuit of Fig. 3 (not shown) a bridge rectifier is in series with the detector and its smoothed D. C. output applied to a relay controlling the warning circuit. In a more complex circuit the bridge rectifier output controls this warning device via a silicon controlled rectifier.

Filed: 1965-01-07
Abstract: 1,026,449. Bearings. ROLLS-ROYCE Ltd. Jan. 7, 1965, No. 830/65. Heading F2A. [Also in Division F1] In a bearing assembly comprising a bearing 17, Fig. 2 (not shown), having inner and outer races 21, 22 with balls 20 and a cage 24 therebetween, lubricant is supplied via an inlet pipe 27 and is collected in a passage 30 which is located beneath the bearing 17 and is connected to a sump 31. The inner race 21 is mounted on a hollow shaft 16 which supports a compressor 12 and turbine 14, Fig. 1 (not shown), of a vertically-mounted gas turbine vertical lift engine 10. An inverted channel member 36, having a base 40 and side walls 41, 42, is mounted in the sump 31, the side wall 41 being adjacent to a wall 35 of the sump 31 but spaced therefrom by a gap 43. A wall 32 of the sump 31 is rotatable with the shaft 16 and has a helical groove 46 therein which conveys lubricant from the sump 31 to an annular groove 47, Fig. 3 (not shown), which communicates with axial grooves 50 in the wall 32. In operation, the pipe 27 supplies lubricant to a space 26 between the shaft 16 and a fixed wall 23 which carries the outer race 22. The lubricant passes through the bearing 17 and is collected in the passage 30 from where it is conveyed through angularly-spaced holes 44, 45 in the shaft 16 and the wall 32 of the sump 31 respectively and is then centrifuged up the internal surface of the shaft 16 and through drillings 51 therein so as to pass over the inner race 21 and through a gap 25 between the races to re-lubricate the balls 20. When the shaft 16 stops rotating, lubricant drains from the bearing 17 into the sump 31 and when the shaft is again rotated lubricant from the sump 31 will be circulated, via the helical groove 46, the axial grooves 50 and the drillings 51 to effect initial lubrication of the bearing. If the engine is inverted, some of the lubricant in the sump 31 escapes through the gap 43 and through the helical groove 46, most of which passes to the bearing 17, the remaining lubricant being trapped in the member 36 so that, when the engine returns to its normal position, there will be a reserve supply of lubricant available for the bearing 17.
