Title: Improvements relating to means for adjusting or setting anti-friction bearings
IPC: F16C19/38
Filed: 1945-05-18
Abstract: 579,798. Ball or roller bearings. BRITISH TIMKEN, Ltd., and WASHBOURNE, W. D. May 18, 1945, No. 12553. [Class 12 (i)] A predetermined end play in a ball or roller bearing shaft mounting is set up by a locating ring which is screw-adjusted along the shaft to give the required axial clearance from the inner race by means of a shrouding ring temporarily attached to the locating ring and extending axially beyond the inner end thereof by the desired clearance, the composite ring (temporary shrouding ring and locating ring) being screwed along the shaft until the longer shrouding ring butting on the inner race has been tightened to take up all play and thereafter the locating ring being clamped in this adjusted position provides the required clearance after the shrouding ring has been removed. Fig. 1 shows a rolling mill shaft 2 supported in a housing 4 by a four-row taperroller bearing mounting of which the outer races 3 and spacing members 5 are fixedly clamped while the inner races 1 are located between a shoulder ring 7 on the shaft and an abutment sleeve 8 which, in conjunction with a locating ring 11 adjusted in position on the shaft, gives the required end play. The abutment sleeve 8 is splined on the shaft while the locating ring 11 moves on a buttress thread 9a provided on two half rings 9 fixed on the shaft. As shown on an enlarged scale in Fig. 3 a shrouding ring 12 is temporarily applied to the locating ring 11 to project beyond the end of the latter by the amount of the required end play clearance 17, the shrouding ring having a shoulder 13 for proper positioning on the locating ring 11, a helical rib and groove or similar means 14, 15 for moving the shoulder 13 into engagement with and then rotating the locating ring 11, and projections 16 or other means by which the composite ring (shrouding ring and locating ring) may be turned so as to tighten up the bearing through the intermediary of the abutment sleeve 8. On removal of the shrouding ring 12 an end play to the amount 17 will exist. The locating ring 11 is clamped in the adjusted position by means of a screw 18 entering a tapped hole 20 in the splined abutment sleeve 8. For unscrewing the locating ring from the shaft the arrangement shown in Fig. 8 is used where after re-applying the shrouding ring 12 there is temporarily bolted to the locating ring 11 an end ring 21 with a shoulder 23 for engagement by the outer face of the shoulder 13 of the shrouding ring; the locating ring will thus be unscrewed from the shaft by the reverse rotation of the shrouding ring when the shrouding ring binds on the shoulder of the end ring 21.

Filed: 1957-04-23
Abstract: 848,219. Granulating slag. COLVILLES Ltd. April 1, 1958 [April 23, 1957], No. 12845/57. Class 82(2) Slag is produced in fragmented form by pouring it into an open-topped moisturefree container to form a single layer. allowing it to cool, applying water solely to the free surface of the layer so as to cool the layer gradually without creating turbulence and foaming, and then allowing the internal stresses set up by the cooling to effect fissuring of the layer. As shown, slag is run off the top of steel ladle 3 through spout 4 into preformed earth pit 5 in the casting floor 6 of the steelworks. The slag 13 is allowed to cool for twenty minutes and is then sprayed with water from hose 14 intermittently for two to three hours. Londitudinal sloping of the pit floor combined with drainage pipe 12 and layer 11 of fine slag particles facilitates drainage of excess water. After spraying, the slag is allowed to cool for two to three hours and the resulting fragments removed from the pit by mechanical shovel 15 which shovels them directly into railway wagon 16 for removal.

Title: Improvements relating to cryogenic liquid transfer systems
Inventor: HART ROBERT REVIE
IPC: F17C9/00
Filed: 1969-03-12
Abstract: 1298553 Pumping cryogenic liquids HYMATIC ENG CO Ltd 10 March 1970 [12 March 1969] 12992/69 Heading F1R In a cryogenic liquid transfer system which comprises a main liquid supply vessel, an auxiliary supply vessel in communication with the main supply vessel through a non-return valve, a supply pipe extending from the auxiliary supply vessel, and a receiver to receive liquid through the supply pipe the auxiliary supply vessel is in communication with a venting valve responsive to the level of liquid in the receiver. As shown, refrigerant liquid e.g. liquid nitrogen, enters an auxiliary vessel 14 via a one-way valve 15 from a main supply vessel 11, e.g. a Dewar flask. On evaporation in vessel 14 due to heat leaking into the vessel 11, liquid is forced along the supply pipe 20 to the receiver 24 e.g. a Dewar flask, until the liquid rises and cools a sensor 33 resulting in contraction of a bellows 30 which contains a volatile liquid, and movement of a needle 29 away from a seating 28. This vents the vessel 14 through a pipe 16, a chamber 27 and a passage above the seating 28 and so the transfer of liquid stops. The pipe 16 may have an injector to assist liquid transfer. The bellows 30 may be assisted by a spring. The chamber 27 has a relief valve 25 responding at a pressure slightly above atmospheric.

Title: Improvements in or relating to apparatus utilising integrating motors
Inventor: OLAH GEORGE
IPC: G05B11/42
Filed: 1952-05-22
Abstract: 716,523. Control of D.C. motors. ELLIOTT BROS. (LONDON), Ltd. May 22, 1953 [May 22, 1952], No. 13048/52. Class 38(3) Relates to apparatus embodying an integrating D.C. motor the speed of which is proportional to the voltage applied to the motor terminals. The motor may have a light-weight armature composed substantially of windings and arranged to rotate in the annular gap between a cylindrical core-piece of magnetic material and the adjacent pole-faces of a permanent magnet. The object is to prevent inaccuracy due to ohmic voltage-drop in the motor when the quantity to be integrated is a current or the electromotive force of a voltage source with substantial impedance. In Fig. 1. the integrating motor 1 is connected to terminals 3 across which a voltage to be integrated is applied, the internal resistance of the voltage source being indicated by resistor r. A substantially constant direct-current is superimposed by a source 4 having a voltage much higher than is required to operate the motor and connected in series with a resistor R of high value. The integration error is wholly or partly eliminated provided the average current taken by voltmeter Rv remains exactly or approximately constant. In another arrangement, Fig. 2 (not shown), a current to be integrated is applied at terminals 3 and a resistor connected across the motor provides a voltage related to this current. In both cases, the substantially constant direct-current passes through the windings of the motor in the same direction as that produced by the quantity to be integrated, and is of such a magnitude that. when the signal current falls to zero, the motor will just stall. Specifications 405,043 and 667,222, [Group XXXV], are referred to.

Title: Improvements in and relating to magneto electric machines
IPC: F02P1/00
Filed: 1925-05-19
Abstract: 257,011. British Thomson-Houston Co., Ltd., and Griffiths, L. May 19, 1925. Magneto-electric machines.-In a magneto in which a portion of the primary volt wave is used for battery-charging, lighting, or other purposes, a centrifugal device is used comprising a rotating member carrying insulated contacts which, when bridged, connect the primary into the lighting or other circuit, and a second rotating centrifugallycontrolled device which bridges the contacts at a limiting speed of the magneto. Figs. 2 and 3 show elevations in the directions A and B respectively on the section line in Fig. 1. A base 1 and a cap member 16 of moulded insulating material are secured together by a bolt 17 and are attached to the magneto contact-breaker 2 by means of a central boss 3 and a bolt 19. The member 16 contains two conducting insets 20, 21, Fig. 3, the former of which makes metallic contact with the bolt 19 while the latter carries a brush box 24, the brush 25 on which makes contact with a fixed segment 28, Fig. 1, connected to the charging or like circuit and moulded in a fixed casing 27. Rotatably mounted on the central bearing pin is a brass disc 8 having sectorshaped holes 9, Fig. 2, into which project shorter but similarly shaped pads 5 formed on the member 1 so that limited angular displacement may occur between the disc 8 and members 1, 16. Normally, the disc is maintained in the position shown in Fig. 2 by means of a spring 15, Fig. 1, so that a brush 13 carried by the disc rests entirely on the inset 20 in the member 16. The members 1, 16 have co-operating pairs of radial grooves 6, 26, Figs. 2 and 3, in which slide centrifugal weights 11 and these members engage also oblique slots 10 in the disc 8. Thus, the outward centrifugal travel of the weights causes relative angular movement between the disc and members 1, 16 until at a limiting speed, i.e. at a limiting value on the volt wave, the brush 13 makes contact with the inset 21 in the member 16 and the lighting or other circuit is closed through the attachment screw 23, contact-breaker 2, bolt 9, inset plate 20, brushes 13 and 25, segment 28 and terminal 29. Further increase of speed increases the area of contact between the brush 13 and inset 21 until equal areas of the brush are on the insets 20, 21, further movement being prevented by the abutment of the pads 5 on the ends of the slots 9.
