Title: Resilient rail spikes
IPC: E01B9/08
Filed: 1945-05-11
Abstract: 611,042. Spikes. MILLS, Ltd., EXECUTORS OF J., and MACBETH, A. May 11, 1945, No. 11831. [Class 89 (ii)] Spikes for securing rails or sole plates to sleepers have shanks with two or more legs 2, Fig. 2, and an arm 4 extending to one side to bear resiliently on the rail flange. The shanks may be unequal in length, may converge or diverge towards their free ends, and may be corrugated to increase their hold in the sleepers. The arm may be bent downward instead of being horizontal and the bends 3 may be curled to form horns which alone bear on the flange. The bends may be such that they first extend towards one side of the spikes and are then bent back so that the arm 4 lies on the other side, the spikes being either within or without the arm. The arm may be wider or narrower than the distance between the spikes or may be of angular or curved shape. In another form, arms 4, Fig. 18, may be connected by an upwardly or downwardly displaced part 12. The initial bends may form a slight shoulder at 16, Fig. 22, and the arms 4 may extend at first away from the shoulder, each arm then being bent back on itself to the part 12. When fixing rails without sole plates the shoulders 16 engage the edges of the flange to prevent lateral shift of the rail, whilst the part 12 resiliently bears on the top of the flange. In this form the part 12 may either be wider than or less than the distance between the spikes. Further forms have three spikes either all in one plane or not. Other forms are punched from sheet metal or are bent up from flat strip, if desired folded so that the spikes are laminated.

As shown, the slurry and the auxiliary liquid are introduced into the bowl through two series of ports 10, 11 respectively provided in the hub of the screw conveyor on opposite sides of the barrier 2. The auxiliary liquid may also or alternatively be fed through the barrier 2. The auxiliary liquid is first introduced continuously and fills the bowl to a level at which it is taken off by the means 5 which is in the form of a liquidphase separator. The slurry is then introduced and, on contacting the surface of the auxiliary liquid, the solids contained therein pass through the latter and are driven along the surface 3 through the auxiliary liquid to the outlet 4 while the liquid of the slurry remains on the surface of the auxiliary liquid. These two liquids are separately removed through the spaces on opposite sides of a barrier 13 in the separator 5, the auxiliary liquid being returned to the bowl through the ports 11. The slurry may be one of paraxylene crystals in a mother liquor comprising at least one other xylene isomer and/or ethyl benzene. The auxiliary liquid may be water or an aqueous alcohol solution to which a freezing point depressant may be added.

Title: Improvements in or relating to fuel-supply systems for gas-turbine engines
Inventor: KAHN PETER BRUNO
IPC: F02C9/16
Filed: 1960-04-05
Abstract: 979,061. Gas turbine plant. PLESSEY CO. Ltd. March 14, 1961 [April 5, 1960], No. 12088/60. Heading F1G. [Also in Division G3] A gas turbine fuel supply system comprises a by-pass valve 4, Fig. 1, of a fuel pump 1, which valve is actuated by gaseous fluid, such as air from the compressor, acting on a diaphragm piston or bellows 8, 9. The servo fluid is supplied through 12 to act on the diaphragm 8 while the pressure on the diaphragm 9 is that between a fined restriction 14 and a leak valve 16 or 15. The housing 17 is rotated at engine speed and the valve 16 opens under centrifugal force against an adjustable loading while the valve 15 opens at a set maximum speed. Instead of opening a by-pass, the valve 4 may control a servo fluid which adjusts a variable displacement fuel pump. The valve 4 may also be opened in response to an increase in fuel flow. In Fig. 3, the valve 4 is controlled as above and may also be actuated in response to torque through control valve 38. The fuel flows from line 5 to the burners past a throttle valve 29 carrying a differential piston 30 subjected to the pressure upstream and downstream of a throttle 34. When the valve 4 closes to increase speed, the pressure on the larger side of the piston increases slowly to increase flow through the valve 29. This increased flow is restricted by a valve 36 subject to the pressure drop across the throttle valve 29.

Abstract: 784,343. Continuous-casting processes. INDUSTRIAL RESEARCH CO., Ltd. April 28, 1955 [Feb. 4, 1955; April 15, 1955], No. 12277/55. Class 83 (1). In continuous-casting, the pressure maintained at the outlet end of the mould, and within the shrinkage-space inside the mould between the solidified metal and the mould, is substantially less than that at the inlet end of the mould. Molten metal is supplied to a horizontal mould assembly 13, from an adjustably-positioned reservoir 12 mounted in trunnions 26 and counterweighted and having a divergent nozzle 35. The mould assembly comprises a chromium-plated copper mould 15, a jacket 67 and coolant pipes 74 having spray nozzles 77. Lubricant, e.g. rape-seed oil, castor oil, mineral oil or an oil-graphite mixture, is periodically applied to the mould, or a metered quantity applied to the inlet end through a pipe 82. A chamber 84 at the outlet end of the mould is connected to a vacuum pump and comprises an inner baffle 95. A coolant such as water is supplied through openings 97 in the chamber and acts as a seal which limits entry of air into the chamber, so that the reduced air pressure is effective along the full length of the mould cavity. The casting is withdrawn by driven rolls which initially grip a starter bar having a tapered and threaded end for engagement with the casting. In a modification, Fig. 9, a vacuum-chamber 3 at the bottom of a vertical mould comprises a flexible seal 4. The upper end of the mould is enclosed by a flexible sleeve 6 having a valve-controlled conduit 8 connected thereto. The valve may be closed so that the pressure within the sleeve 6 tends to equalize with the reduced pressure in the chamber 3, or air or an inert gas, e.g. propane, nitrogen, argon, may be admitted.

Abstract: 892,832. Quenching coke. WOODALL-DUCKHAM CONSTRUCTION CO. Ltd. March 23, 1960 [April 10, 1959], No. 12299/59. Class 51 (2). During discharge of coke from a battery of ovens, the coke car 8 is covered by a flexible cover 23 cooperating with a pivoted hood 10 attached to a closed conduit on the coke guide 5, said cover 23 being replaced for transit to the quenching station by a rigid cover 22 carried by a car 27. The hood 10 is actuated by hydraulic rams 14 and the flexible cover comprises mild steel slats 34 articulated on spindles 35 carrying rollers 36 travelling on rails 28 on the top of the coke car and adapted to be reeled on to a spring-loaded drum 24. The rigid cover 22 is made of refractory lined mild steel or spheroidal graphite iron and has rollers 30 travelling on rails 29 on the carrier car and also on rails 28, and is withdrawn from the coke car by cable 31 actuated by a motor 33 and drum 32 on the carrier car. The hood 10 engages a bracket 39, Fig. 3, on the first slat 34 of the flexible cover and has latches 40 engaging a bar 41 at the end of the rigid cover 22. In operation, the locomotive 9 moves rearwardly from the quenching station until the bracket 39 adjoins hood 10, whereupon the latter is lowered to engage said bracket, further movement causing the flexible cover 23 to be drawn over the coke car. At the end of its travel, latches 40 engage the bar 41 and pushing of the oven commences, the locomotive then being reversed. Reverse movement allows the flexible cover to be rewound on its drum, drawing the rigid cover 22 off the carrier car until it finally covers the coke car at the completion of the pushing operation. The locomotive then pushes the cars to the quenching station, whereupon rigid cover 22 is withdrawn by motor 33 which may be automatically switched on. In a modification, Fig. 12 (not shown), cover 22 may be made to fold in concertina fashion, shortening carrier car 27.
