Title: Improvements in variable stroke radial pumps
IPC: F04B1/04
Filed: 1938-10-26
Abstract: 524,199. Revolving cylinder pumps. WYLIE, H. N. Oct. 26, 1938, No. 30925. [Class 102 (i)] A variable radial stroke pump of the kind in which the stroke of a number of radial pistons is controlled by an eccentric track ring and which is especially applicable to engine-driven hydraulic pumps in an aircraft having auxiliary hydraulic services is constructed with a track ring 2 pivoted at 3 to a fixed casing 1 the ring being movable about the axis 3 to vary its eccentricity under the action of forces due to the pressure of the fluid and to the pressure of a curved spring 4 which is arranged between abutments 5, 6 on the casing 1 and ring 2 and is adapted to act like a Ealer strut. The valve means which determine the direction of the total reaction of the piston and cylinder assembly on the track ring are disposed with a bias such that this direction is such as to produce a component of force tending to reduce the eccentricity against the force exerted by the controlling means. The turning movement due to liquid pressure is dependent on the speed of the drive sleeve 17 which is integral with the cylinders 8 of the pumps, and upon the setting of a stationary valve 9 which controls the flow of liquid to and from the cylinders in conjunction with the movement of the pistons 14. The pistons are fitted with slippers 16 which move in the tracks of the ring 2, and which impart reciprocating motions to the pistons dependent upon the eccentricity of the ring 2. The pumping action of the pistons 14 is preceded by a centrifugal stage in which the cylinders 8 and associated parts act as a rotor and discharge liquid admitted through a port 1E to an outlet channel leading to ports 10B, 10A and thence to the inlet port 10 of the valve 9. This port 10 is separated by bands 12, 13 from the outlet port 11 of the valve, and the pumps take in liquid when passing the port 10 and discharge it when passing the port 11 which leads to the outlet pipe 11C in which is a relief valve 11B. The pump is adapted to act with a maximum delivery pressure above which the delivery rate falls off to zero or to a small value owing to the track ring being restored to a concentric position relativelv to the axis of the sleeve 17. This sleeve 17 is driven by a shaft 7C by means of an Oldham coupling 26.

Title: Improvements relating to the catalytic hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1931-11-11
Abstract: <PICT:0389560/III/1> In the destructive hydrogenation of carbonaceous materials, the temperature of the reacting materials is controlled by injecting cooling oil through nozzles distributed through the reaction zone.  The injected oils are preferably free from ash and asphaltic substances and comprise preferably middle oils produced by hydrogenation.  A reaction vessel 1 filled with catalyst is provided with gastight closures 3, 4.
