Title: Railway train control systems
IPC: B61L3/22
Filed: 1926-12-04
Abstract: 262,469. Continuous Train Control Corporation, (Assignees of Clark, T. E., and Clark, J. E.). Dec. 5, 1925, [Convention date]. Fluid-pressure.-In an automatic braking system for railway vehicles in which highfrequency current is supplied to insulated track rail sections under predetermined conditions and is adapted to act inductively on train carried apparatus to apply the brakes, brake application is controlled by a normally-energized electromagnetic valve mechanism 118. The circuit of magnet 118 includes " forestalling " and " resetting " contacts, not shown, and pneumatically operated contacts 117. Fig. 12 shows the general arrangements of valves, which are described in detail. An inlet valve 405 and exhaust valve 409 are normally respectively held open and closed when device 118 is energized. Air is thus supplied to the underside of a piston maintaining contact 117 closed, to a reservoir 422, to the underside of a piston 423 maintaining open a valve 428 interposed between pipe 434 leading to the usual engineer's valve, not shown, and brake-pipe 435, and to one side of a piston operating a slide-valve 431. When device 118 is de-energized, the above mentioned air supply exhausts slowly through valve 409 and sounds a warning whistle 420, time being allowed for depression of the forestalling " key before contacts 117 open. Valve 428 seats, preventing recharging. of the brake-pipe but allowing further reduction of pressure by the engineer's valve. A by-pass 437 around valve 428 is normally held closed and sealed, and a cock 439 is provided for blocking the engineer's valve when the locomotive is coupled in a train handled by another locomotive. Brake-pipe 435 is connected through a strainer 441 and pipe 442 to the upper side of slide 431 and through a post 443 to the under side of a piston 445 which normally seats a valve 446 owing to an equal pressure being supplied to the upper side of the piston through the slide 431. The space above piston 445 is connected through a port 449 to a reduction reservoir 451 and to the under side of a diaphragm 460 carrying a needle valve 453, and through the normally open valve 453 to a port 455 below slide 431. The space above a diaphragm 459 is connected to a holding reservoir 457 and to a port 458. When exhaust occurs through whistle 420, slide 431 is moved to the right, cutting off supply to space above piston 445, and connecting port 455 to a restricted vent 461. Reservoir 451, space above piston 445, and space under diaphragm 460 exhaust until valve 453 closes, retaining remaining pressure in reservoir 451. Valve 446 is unseated, and the brakepipe 435 is vented until the pressures above and below piston 445 are equalized, the action of piston 445 being similar to the function of the usual equalizing valve of automatic air-brake systems.

Title: Manufacture of finned tube
Inventor: HALL ARTHUR SAMUEL
IPC: B21C37/26
Filed: 1957-10-03
Abstract: 843,508. Making finned tubes; welding by pressure; coiling strip on tubes. TUBE PRODUCTS Ltd. Sept. 26, 1958 [Oct. 3, 1957; March 21, 1958], Nos. 30963/57 and 9129/58. Classes 83 (2) and 83 (4). In making a helically-finned tube a strip 16 is wound on the tube 10 in edge contact under controlled substantially radial pressure and a welding-current at a frequency between 100,000 and 5,000,000 cycles per sec. is applied through brushes or electrodes 40, 47 engaging the strip and the surface of the tube at points adjacent to the point of engagement of the strip with the tube, the tube and means for feeding the strip and applying the current being relatively movable in the direction of the tube axis. In an embodiment, the tube, e.g. of steel, is mounted in a lathe 13 for rotation without axial movement and a carriage 15 movable on the lathe bed parallel to the tube axis carries means for feeding and applying pressure to the strip and means for applying the current to the tube and strip. The strip, e.g. of steel, is drawn from a reel 17 at one end of the lathe through rollers 18 supported by an arm 19 travelling on an overhead runway, downwardly over a roller 20 and between grooved rollers 21, 22 on the carriage to be fed tangentially to the tube. The strip is pressed into contact with the tube by a grooved roller 24 adjustably mounted on a housing movable towards and away from the tube by an adjusting wheel 32. A flat copper alloy blade 40 slidable under spring pressure in a holder engages the tube in alignment with the strip, the holder being secured to a copper plate 42 extending from a transformer 60 on the carriage. A horizontal L-shaped copper alloy bar 47 rockable between abutments on an arm 49, Fig. 4, secured to a second copper plate 421 extending from the transformer is spring-urged against the inner edge of the strip. The transformer picks up current through contacts 61, 62 engaging bus-bars 63, 64 extending the length of the machine and supplied with current at 450,000 cycles per sec. from an oscillator 69. The roller 24 and other parts adjacent the weld point and the tube and welded fin beyond the weld point are sprayed with water. The end of the strip may be held in the chuck or clamped on the tube at the start of the operation when the tube is rotated, the current switched on and the carriage moved along the lathe bed. Turning tools, milling cutters or grinding-wheels may be used to remove weld flash. The strip may be curved in a reverse direction to that in which it is wound on the tube before it is wound on the tube. In a modification the tube is held in a rotary chuck on a carriage driven along a bed and the means for applying the strip are carried by a stationary support. The strip may be of tapered &c. cross-section and may be waved or corrugated. One of the Provisional Specifications refers to welding a fin on a rod.

Patent GB-314058-A (GB)
Abstract: 314,058. Friden, C. M. F. June 23, 1928, [Convention date]. Grant of Patent refused. Multiplying and dividing apparatus.-In a machine for the four rules the differential actuators for the product totalizing-counter and the actuator for the revolutions or quotients counter are arranged coaxial, means being provided for reversing the relative direction of rotation of the two actuators. As shown applied to a machine with a reversible rotary actuator, similar to that described in Specification 207,858, the actuator for the totalizer comprises a set of selecting elements 7 of known form and the actuator for the revolutions-counter comprises a single toothed element 39, Fig. 4, both actuators being provided with a set of tens transfer members with pins 6. The actuator shaft is constituted by two parts 5, 5A connected by a socket 34 and pin 35. On the shaft 5A is mounted, on roller bearings 36, a hollow shaft 37 carrying the transfer units 38 and the actuating member 39. The shaft 5A is rotated by a hand crank through gearing one wheel 45 of which is secured to the shaft. Secured to the hollow shaft 37 is a gear 46 and mounted on a stub axle on the side frame is a gear 48, Fig. 2, in mesh with the gear 45. The stub axle carries a rockable arm 49 on which is mounted a pair of gears 51, 52. The gear 51 meshes with the gear 48 and can be moved into and out of engagement with the gear 46; the gear 52 can be moved to engage simultaneously both gears 45, 46. In performing multiplication the shafts rotate in opposite directions and in division operations in the same direction. This is effected by the depression of one or other of a pair of control keys 54, 55 to effect the rocking of a lever 57 connected by a link 58 to the arm 49. The totalizer comprises a series of numeral wheels 81, and the revolutions counter a series of numeral wheels 82 each series being independently mounted on a common shaft and operatively connected through intermediate pinions 85, Fig. 2 with the actuators and usual transfer levers. The Specification as open to inspection under Sect. 91 (3) (a) comprises also means for controlling the key locking and release means, means for traversing the carriage, and means for zeroizing the totalizer and revolutions counter. The keyboard interlocking means forms the subject matter of Specification 338,990, and the zeroizing mechanism forms the subject matter of Specification 335,905. The carriage traversing means comprises a rear plate 66 mounted on the carriage 65, carrying a rack 67, Figs. 2 and 20 (Cancelled) engaged by a pinion 68 connected through gearing 69, 71, 72, with a shaft 73 which extends to the front of the machine and ends in a hand wheel 74. The step-by-step spacing of the carriage is ensured by means of a roller 76 on the end of a spring-controlled lever 77 engaging the serrations of a plate 75 secured to the rear plate. This subject-matter does not appear in the Specification as accepted.
