Title: Improvements in or relating to automatic control of fluid-operated piston devices
IPC: F15B15/22
Filed: 1962-06-15
Abstract: 1,038,136. Fluid pressure engines and motors. J. HANDLEY. July 18, 1963 [June 15, 1962], No. 23239/62. Headings F1M and F1P. In a piston engine comprising a cylinder and inlet and outlet ports for the entry and exhaust of operational fluid, an outlet port which communicates with the cylinder is provided with a valve which is directly responsive to cylinder pressure and which is arranged to adjust the cross-sectional area of the port in response to changes in fluid pressure in the cylinder volume. After the piston 7 has passed the sealing ring all fluid retained in the cylinder end must pass through the hole 11 in the damping piston 12. Pressure increases in the cylinder end 10 and this pressure forces piston 12 to more towards the tapered needle 15 further restricting the exhaust. The damping valve could alternatively be arranged to open in response to increased pressure in the cylinder. The device may be of gaseous pressure operated or liquid pressure operated type. Several engines of various lengths may be connected in tandem the piston rod of one to the cylinder of the next and may be mounted so that both pistons and cylinders can be moved in different directions.

Title: Improvements in taper roller bearings
IPC: F16C19/36
Filed: 1948-09-04
Abstract: 650,639. Conical roller bearings. FRENKEL, M. S. Sept. 4, 1948, No. 23354. [Class 12 (i)] Skewing of the tapered rollers 11 of a bearing comprising two conical race rings 12, 14, the latter having a roller locating flange 6, is prevented by maintaining constant the angular velocity, with respect to each track, of each roller when operating at constant speed. Two conditions are stated to effect this. The distance between the generatrix of the race track 8 of the ring 14 and the centre of gravity Q of the roller end surface area enclosed by the flange 6 is determined by a function, given in the Specification, of the bearing dimensions. Also each roller 11 has a mass-distribution relative to its effective rolling surface which locates, by a further function given in the Specification, the centre of gravity C of the roller between its narrow end cross-section and its cross-section which contains the centre of gravity of the total length of the generatrix of the conical rolling surface 9. The Provisional Specification describes also various configurations of rollers to obtain these conditions, and a construction of rollers of two differing materials having differing specific gravities, or filled with a material such as oil under pressure.
