Abstract: 1450898 Self-levelling hydropneumatic suspension units GIRLING Ltd 6 Nov 1973 [2 Dec 1972 5 April 1973] 55776/72 and 16235/73 Heading F2S A self-levelling hydropneumatic suspension unit comprises a piston 4 slidable in a cylinder 1 and connected to a piston-rod 5 extending through an end closure 3 of the cylinder, an inlet valve 15 in the end closure 3 for controlling flow of liquid into the cylinder 1 from a source (not shown), and a spring 29 co-operating with the piston 4 to control operation of the inlet valve 15, the maximum length which the spring 29 can attain being limited by a collapsible sub-assembly 30. A chamber containing gas and liquid is connected to the cylinder 1 through connection 38. The outlet from the cylinder to a reservoir (not shown) is via an annular drain chamber 24. The sub-assembly 30 comprises two (or three, Fig. 3, not shown) telescopic sleeves. The inlet valve is biased open constantly by the pressure from the source, and closed by the spring 29 when the unit is extended. In operation, with the unit contracted under increased load as shown, the spring 29 is away from the inlet valve 15 which is therefore open to allow flow from the source via the annular cylinder chamber surrounding the piston-rod 5, a levelling part 12, channels 11 and 9 in the piston-rod, and passages (not shown) in the piston 4 to the cylinder chamber above the piston. The unit extends, the piston 4 moving out until the spring 29 closes the inlet valve. At this stage the levelling port 12 is above the high pressure seal 23. Should the static load be reduced, the unit extends so that the levelling port 12 communicates with the annular drain chamber 24. Liquid flows from the chamber above the piston 4, through the piston-rod, the port 12 and the chamber 24 to the reservoir (not shown) and the unit contracts until the port 12 moves out of co-operation with the chamber 24. The inlet valve is still held closed by the spring 29.

Title: Process and apparatus for decomposing gaseous metal compounds
IPC: B01J23/755
Filed: 1962-05-01
Abstract: A process for decomposing a gaseous thermally unstable metal compound comprises passing the compound through a charge of heated particles in a reactor which is rotated about a horizontal, or slightly inclined, axis so causing the charge to tumble gently while the compound is decomposed to deposit the metal on the particles.  The compound may be a carbonyl of Ni, Fe, Co, Cr, Mo or W, the nitroxyl carbonyl of Co, the hydrides of Sn or Sb or the iodide of Be or Ni. More than one metal compound may be used to give an alloy coating. The particles on to which the metal is deposited may be metallic or non-metallic and may be, for example, the same metal as is being deposited, a different one, metal carbides, Al2O3, MgO, Ti2O3, Zr2O3 or ThO2.  The meta coated ceramic, refractory or other non-metallic particles may then be heat-treated for diffusion, annealing or dispersion hardening. Ceramic particles so coated may be pressed sintered or heat treated to form cermet materials and dispersion hardened alloys. The decomposition temperature should be above 350 DEG F., preferably above 400  DEG F., and the particles are preferably preheated to a temperature not above 550  DEG F.  Ammonia may be added with carbonyl vapours to inhibit carbon formation. The rotation speed should generally be less than 3 r.p.m.  A valve means is used on the gas inlet so that the gas only enters through the particles (see Division F2).
