Title: Brake pressure control device
IPC: B60T8/26
Filed: 1971-08-24
Abstract: 1327182 Fluid pressure brakes KELSEYHAYES CO 24 Aug 1971 [24 Aug 1970] 39670/71 Heading F5F A pressure proportioning device 10 is disposed in a line between a master cylinder 12 and rear brake cylinders 28 and at two different inlet pressures provides a different modulating effect on the rear brake cylinder pressures. In normal brake operation when the master cylinder pressure is below a predetermined value fluid passes via an inlet 36, radial slots 112 provided in a check valve housing 104, past a valve 120 formed by a raised portion 118 of housing 104 co-operating with a conical opening 82 formed in a piston 68 and through bores 84, 66 in piston 68 and a plug 34 respectively to cylinders 28. When the pressure acting on the right hand face of piston 68 is greater than a first predetermined value, piston 68 moves leftwardly closing valve 120. The pressure to the rear brake cylinders is thereby modulated until the second predetermined pressure value is reached. At this value the pressure acting on the left hand faces of a member 100 overcomes the forces of springs 88, 98 and member 100 moves rightwardly causing an abutment shoulder 96 thereon to abut piston 68 which thereafter moves in unison with member 100. Hence the total surfaces on the right and left hand faces of member 100 and piston 68 is altered, modifying the movement of piston 68 and producing a different modulating effect on the rear brake pressure.

Abstract: 865,879. Boring earth. KVELLO-AUNE A. G., and TROFTEN, P. F. Nov. 25, 1959 [Nov. 26, 1958], No. 40067/59. Class 85. In a rotary drilling apparatus, the drill string is rotated by either or both of two chucks spaced axially along the string, the chucks being independently displaceable along the string so that whilst one chuck, operative for the time being, is coming to the limit of its feed movement, the other, temporarily inoperative is moved to the beginning of its feed movement to take over the drive of the string without interrupting its rotation Figs. 1, 2 joined end to end, show identical upper and lower chucks 2, engageable with a drill string 9 and driven by a motor 72 on a housing 7 carried by a frame 80. The chucks comprise a stationary outer casing having a recessed wall 40 forming, with a sleeve 34 an annular cylinder for a piston 38 attached to the sleeve, ports 44, 46 admitting pressure fluid above and below the piston. The axial movements of the sleeve 34 are transferred by bearings 30, 32 to a tapered member 28 which bears on wedge-shaped toothed pipe-engaging dogs 10. Roller bearings 16, 18 and the bearings 30, 32 permit the pipe-gripping means to be rotated to the outer casing and sleeve 34, the rotation being effected by the motor 72 which drives, by chain and sprocket 70, a hollow shaft 21 in which a hollow shaft 20, attached to the clutch parts, is telescoped, driving splines 64 being provided. The chucks are attached to tubular members 3, 4 which have an annular piston 56 secured thereto, the piston working in a cylinder 60 in casings 5, 6 having ports 59, 61, 591, 611 for the supply and exhaust of pressure fluid, the chucks being thus independently adjustable axially of the drill string, and provided with the requisite downward thrust for the drill feed. The machine may be provided with a known time controlled valve system, so that it operates on a timed cycle. The removing of pipes from the bore may also proceed continuously. The cylinder 60 may be replaced by two or more hydraulic units spaced around the drill pipe, and one motor 72 may be provided for each chuck. In a modification, one chuck only is axially movable, this chuck taking over the drive, without feed, whilst the other chuck is being axially re-positioned.

A pulse generator comprises a pulse forming network in series with resistance equal to its characteristic impedance and charged via a first switching device so as to generate one pulse, then discharged via a second switching device so as to generate a second pulse of opposite polarity. As shown in Fig. 6, a positive pulse at P1 triggers a silicon controlled rectifier SCR1, charging the pulse forming network PFN from capacitor C1, thus generating a current pulse in a multi-aperture square loop core connected to 02. The PFN is discharged by SCR2, triggered by a negative pulse at P1 thus generating a current pulse at O1. Bipolar voltage and current pulses are available at 04 and 03, the latter pulses may be delayed by connecting a saturable reactor across 03. Fig. 7 shows a circuit for obtaining bipolar pulses of different duration by use of networks of different delay times, the shape of the pulses being controlled by resistors R4, R5. The H.T. supply may be D.C. or a sine or square wave synchronized with the trigger pulses. The SCR's may be replaced by transistors, four layer diodes, valves or thyratrons.

Title: Improved catalytic metal or alloy surfaces
IPC: C23C14/16
Filed: 1962-10-31
Abstract: A lithiated catalytic material capable of forming a continuous surface is made by depositing lithium onto a host metal or alloy, preferably selected from the Group IB and VIII metals i.e. Cu, Ag, Au, Fe, Co, Ni, Ru, Rh, Pd, Os, Ir and Pt, and heating the metal/alloy-lithium system between 250 DEG C. and the melting-point of the host metal or alloy.  The lithium may be present in amounts from 10-200 micrograms per sq. cm. surface area, and may be incorporated into the surface by immersing the host metal or alloy into molten lithium or a eutectic melt of Li diluted with Ca or Ba, such as 30% Li-70% Ca alloy, removing it and heating it in an atmosphere of A or He to 400-450 DEG C., excess Li being removed by immersion in water.  Pt foil, Pd or Ni sheet, and 25% Ag-75% Pd wire are specified as the host metal or alloy.  Alternatively, the host metal or alloy, e.g. 1% Ag-99% Pd foil, may be immersed in a solution of a lithium halide e.g. 10% LiBr in pyridine or acetonitrile, and the lithium electrodeposited e.g. under an A atmosphere prior to heating to 480 DEG  C.  Another method comprises dissolving Li in liquid ammonia from which the Li may be deposited by electroplating or without by diffusion under an atmosphere of He or A.  Vapour deposition may be used, e.g. for producing a lithiated 14% Rh-86% Pt alloy sheet, wherein the Li may be evaporated from a Mo boat in an evacuated apparatus and the lithiated host metal or alloy thereafter heated e.g. to 500 DEG C. between W heating elements. The lithiated catalytic material may be in powder or granular form for use in hydrogenation, polymerization or reforming processes, or nonporous e.g. Pd or Pd-Ag alloy for use in constructing hydrogen purifiers, or sintered porous for constructing fuel cell electrodes (see Division H1).ALSO:A lithiated catalytic material capable of forming a continuous surface is made by depositing lithium on to a host metal or alloy of Group IB and/or VIII metals and heating the metal/alloy-lithium system between 250 DEG C and the melting-point of the host metal or alloy.
