Title: Improvements in or relating to tempering apparatus
IPC: C21D9/00
Filed: 1921-05-11
Abstract: 185,473. Ewing, C. A. May 11, 1921. Tempering.-Apparatus for continuously tempering steel track rails comprises a rotating drum 6 having clamping-arms 37 on its periphery into which arms the heated rails are fed, the drum being provided with means for directing a cooling-medium, supplied to its interior, on to the parts of the rails to be hardened before they are released at the point of discharge. Mechanism for feeding rails along bars 52, Fig. 2, leading from the rolling-mill comprises a sliding rack 53 carrying counterweighted bellcranks 54 pivotally supported at 54<1> and adapted to engage the rails on the forward motion of the rack, which is reciprocated by a toothed segment 55 rocked by a rod 58<1> eccentrically coupled to a wheel 19 geared to the drum-rotating mechanism. The clamping-arms 37 of an axially-aligned series, on receiving a rail from the bars 52, are drawn towards the axis of the drum bv links 41 eccentrically connected to discs 40, which are partly rotated at this point by arms 45, Fig. 5, operated by a stationary cam 49 secured to the bearings of the drum. The head of the rail is thus forced between the opposing flanges of spring-pressed plates 31 which serve to close pockets 21 formed in the periphery of the drum thus preventing the cooling-fluid admitted to the pockets from impinging on the webs and flanges of the rail. Cooling-fluid, such as compressed air supplied by a perforated pipe 9, disposed axially of the drum, is admitted to the pockets 21 through ports 23 on valves 26 being raised by the head of a rail. The rails are subsequently released on to a guideplate 61 by a backward rotation of the discs 40 caused by the cam 49. The points at which the clamping-arms 37 are operated may be adjusted to suit the height of the drum in relation to the bars 52 by rotating the cam 49 within the limits of its pin-and-slot connection 50, 51 with the bearing. In a modification, Fig. 3, the flanged plates 31<1> for directing the quenching-fluid are positioned by slidable rack-bars 33<1> operated by toothed wheels 62. The clamping-arms 35<1> may be adjusted circumferentially of the drum bv a sliding rack 63 and toothed wheel 64. In further modifications the flanged guide-plates are replaced by pivoted tubular jaws adapted to engage the head of a rail or by longitudinal ribs formed on the periphery of the drum.

Title: Improvements in or relating to hydraulic reciprocating pumps
IPC: F04B49/08
Filed: 1963-04-04
Abstract: 989,135. Reciprocating pumps. WEATHERHEAD CO. April 4, 1963 [May 4, 1962], No. 13404/63. Heading F1A. In a swash plate pump, the non-rotatable cylinder block 55 is axially movable in dependence on the pump output pressure to adjust the effective stroke of pistons 70 controlling inlet ports 64, 66, so that the pump output volume is inversely proportional to the output pressure and the driving power required by the pump is maintained substantially constant. The output pressure at outlet 22 acts on the end 131 of a valve spool 125, via passages 106, 109, against a spring 142. When the output pressure is low, spring 142 moves spool 125 leftwards to connect a chamber 137 to the pump casing via passage 136, groove 128 and passage 134, thereby permitting spring assembly 102 to hold block 55 in its rightward position for maximum volume output. If the output pressure exceeds the level determined by spring 142, spool 125 is moved rightwards to connect chamber 137 to outlet 22 via spool groove 127. The output pressure in chamber 137 acts on the right-hand end of a piston 117, via passage 145 and chamber 147, to move block 55 leftward against spring assembly 102 and thereby reduce the pump output volume. Block 55 is also biased against spring assembly 102 by the output pressure continuously acting on the right-hand end of a piston 163 engaging piston 117. Spring assembly 102 comprises springs 151, 154 of different rates to provide a non-linear force. Springs 151, 154 may be replaced by a multi-rate spring or by several springs of different rates, and are initially pre-loaded so that no movement of the block takes place until a predetermined output pressure is reached. Pump pistons 70 deliver to outlet 22 via reaction pistons 85 and valves 93, pistons 85 being biased against the pump housing by springs 97. Swash plate 46 is held against rotation by a guide block 51 slidable in a housing channel 52. The pump housing is maintained full of liquid via inlet 16.

Abstract: 586,200. Turbines. BAUMANN, K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 21, 1944, No. 14019. [Class 110 (iii)] In order to maintain a bladed-drum rotor, operating under high temperature conditions, accurately aligned with its bearings, the drum is mounted on a coaxial shaft by at least two axially spaced means at least one of which means permits differential thermal expansion in both the radial and axial directions whilst at the same time maintaining coaxiality of the shaft and drum. In the arrangement shown, Fig. 1, the drum 1 is mounted on the shaft 2 by means of a conical member 4. The member 4 is bolted to the flange 2b at the inner diameter and at the outer diameter is formed with a channel 4c in which the drum is held by rivets or taper pins 7. A flexible cylindrical extension 1a on the drum and, the re-entrant form 4b of the member 4 permit differential expansion of the drum in the radial direction. The other end of the drum is supported by another conical member 6 which is attached to the drum in the same manner as the member 4 but is mounted on the shaft 2 by splines 5 which allows longitudinal expansion of the drum. In a modification, the conical member 4 is made integral with the drum and may merge with the drum at its end or anywhere on the inner surface. In a further modification, the splines 5 are formed on the outer diameter of the conical member 6 and may mate with splines formed on a separate member bolted to the drum. Splines may be used to connect the drum to both of the conical members 4 and 6, but in this case the drum must be located axially by means of radial plates at one end. The end discs 4 and 6 may have holes provided so that cooling air for the shaft may be used. Specifications 16823/04, [Class 110], and 586,041 are referred to.
