Abstract: 388,836. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Coolidge, W. D. ; 36, Bedford Road, Schenectady, New York, U.S.A.) Sept. 23, 1931, No. 26577. Convention date, Sept. 23, 1930. [Class 39 (i).] A window for a cathode-ray, R÷ntgen-ray, or alpha-ray tube is prepared from a blank of aluminium or beryllium by deformation by cold flow under pressure so as to form thin areas allowing the passage of the rays and bordered by thicker areas offering sufficient support to resist atmospheric pressure ; the window may have an additional supporting structure and is sealed to a support by soldering. The blank 7, Fig. 2, is held on a block 10 by a clamp consisting of a rod 15 which slides in bearings 16 carried by clamped supports 17, and is forced downwards by a spring 18 bearing against an adjustable collar 19. A very thin ring of aluminium solder 9<1>, without flux, is applied to the blank, and the block is heated by a burner 14. Rods 13 facilitate rotation of the block. The blank is removed from the clamp and soft solder with a minimum of non- corrosive flux is applied to the aluminium solder. Grooves and projections are formed in the blank by means of a grooved punch 8, Fig. 4, inserted between a ram 24, Fig. 5, and the blank which is mounted on a metal block 221. A ring 9 on the punch prevents buckling of the blank. The thickness of the bottom of the grooves is less than one-half mil. A copper cap 25, with a central aperture 27, is secured to the anode 5 by hard silver solder, the blank is pressed with the soldered edge against the cap, and a flame is played about the periphery to melt the solder. Solder 28 may also be applied around the cap. In a modification, the blank is formed by counter-boring an aluminium block which is butt-welded to a flanged copper cap soldered to the anode. An additional supporting grid may be provided, with the ribs at right-angles to those of the window.

Title: Improvements in release valves in railway pneumatic braking equipment
IPC: B60T15/54
Filed: 1963-07-05
Abstract: 1,009,279. Brake release valves. COMPAGNIE DES FRIENS ET SIGNAUX WESTINGHOUSE. July 5, 1963 [July 12, 1962]; Jan. 10, 1963], No. 26732/63. Heading F2F. A release valve comprises a closure member 11 mounted on a piston 13 in a cylinder 14 adapted for connection to the main brake pipe in railway braking equipment, a first chamber 5 adapted for connection with the pneumatic circuit of the equipment, a second chamber 18 always vented to atmosphere and separable from the first chamber by the closure member which has a larger diameter than the piston on which it is mounted, such that in operation the open or shut condition of the closure member is dependent on the combined pressures in the chamber 5 and cylinder 14. To empty the chambers which control the brakes, the latter having been applied to the maximum so that atmospheric pressure is present in cylinder 14, the control rod 21 is moved obliquely to move the closure member upwards off its seat 12. The chambers then vent to atmosphere through calibrated orifice 27. Even though the pressure in chamber 18 is lower than in chamber 5 it is sufficient to maintain the closure member off its seat when the rod 21 is returned to its normal position by spring 22 because it is acting on a greater surface area of the closure member. When the brake pipe is charged the control rod 21 must be held actuated as long as the venting is to continue.

The radially slidable hammers which are actuated by engagement with rollers 104 on a fixed or rotating carrier 97, 98 are biased outwardly by springs 41 abutting cross members 54 passing through slots in the hammers. These hammers actuate hammer dies 83 radially slidable in a housing 78 and biased outwardly by springs 86. In one embodiment, Fig. 1, the machine has four sets of hammers 25-28 and hammer dies 29-32 in series both being rotated by a shaft 3 driven through clutch 7, 8 by a pulley 6. The outer ends of the hammers co-operate with sets of conical rollers 13 and the hammer block 10 may be moved axially by hand wheels 20, 23 for varying the relative axial position of the rollers and hammers and hence the effective stroke. The workpiece which may be a bar or tube is fed through a nozzle 36 and guide tube 37 whose position is adjustable axially by a hand wheel 39. In a similar embodiment, Figs. 6, 7 (not shown), the hammer dies do not rotate and the rollers 13 in adjacent sets are staggered. In another embodiment, Fig. 8, the hammer block 88 and die housing 78 are driven through splines 77, 92 from the shaft 3 and pulley 107. The hammer block 88 is adjustable axially by a nut 90 and the die housing 78 by hand wheel 23. Ball-bearing type conical rollers 104 are mounted on pins 102 carried by a split rotating housing, 97, 98 provided with belt grooves 106. Both pulley 107 and housing 97, 98 are driven by separate electric motors in the same or opposite directions through change-speed gearing whereby the rate of striking may be regulated from maximum to zero without stopping the motors. In a modification, Fig. 11 (not shown), the ball bearing rollers are cylindrical but are mounted on inclined pins ; adjustment for wear is provided for the rollers. The hammers may slide in brass or bronze sleeves, Fig. 12 (not shown), and may have shaped outer ends to provide for a slower inward movement than outward movement. In a further embodiment, Fig. 16, the hammers 161-165 act directly on the work and are actuated by elongated inclined rollers 138 carried by a rotating housing 135. Axial adjustment of the rotating hammer block 146 is effected by a hand wheel 159 through gearing 158 and threaded nut 150.

Title: Apparatus for controlling a stepping motor
IPC: G06K13/20
Filed: 1965-06-25
Abstract: 1,048,065. Stepping-motors. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 25, 1965 [July 2, 1964], No. 26936/65. Heading G4H. Oscillations in stepping-motor operation are reduced by logic means which render irregular the interval between pulses in a stepping pulse train at the beginning and/or end of a stepping operation. In Fig. 4 (not shown), the gaps after the first and third pulses of a regular pulse train are inverted and passed to the motor, under control of the 2 degrees stage of a binary counter also fed with the regular train, then the fifth and subsequent pulses are fed to the motor under control of a latch set by the 2<2> counter stage. Thus the motor initially receives pulses at less than the stalling rate and accelerates to above it. For stopping, regular pulses fed to the motor can also be fed to a binary counter and when the latter reaches a certain count, it cuts off the regular pulses and triggers single-shots to produce two further stepping pulses at progressively longer intervals (Fig. 6, not shown). Fig. 8 (not shown) shows the use of a counter and single-shots to produce a pulse which effectively grounds all the stepping motor windings to retard the rotor just before the final regular pulse arrives at the motor, the counter cutting off further regular pulses. Fig. 10 (not shown) shows logic circuitry including single-shots, for producing from a regular pulse train stepping pulses of cyclically varying duration and spacing, so that for each step the motor receives an accelerating pulse, a decelerating pulse and then (when substantially in the desired step position) a pulse of the accelerating type to hold. The same single-shots are used for all motor windings, but in a modification (Fig. 12, not shown) two separate sets are provided. Single-shots are adjustable to optimize operation.
