Title: Potentiometric hydraulic shock absorber - with sensing element which detects shaft displacement and actuates damper brake progressively
IPC: B60G17/06
Filed: 1974-11-29
Abstract: A sensing element is the most important part of this hydraulic shock absorber design. The element comprises a cylinder (10) in which piston (12) on shaft (16) slides to and fro, dividing the cylinder into two compartments (13) and (14). A small passage (15) in the piston connects the two compartments each of which is also connecte by a line to the valve (19). This valve has an oscillating piston, spring loaded and of such a size that chambers (13, 14) are always connected, but by differing restrictions, to the line (18) and thus to the actuator valve (17). When shaft movement produces a pressure in either chamber (13, 14), pressur ein line (18) does not rise until a certain displacement of the piston invalve (19) occurs. Further pressure actuates valve (17) which then applies a brake (20) to the shaft, damping further motion progressively.

Title: Liquid fuel gasification - using medium pressure chamber heated to above dew point to vaporize fuel fed to heated chamber
Inventor: LEPAGE LOUIS
IPC: F23D14/66
Filed: 1975-01-20
Abstract: Liquid fuel is vapourised by passing it into a first chamber at medium pressure, the chamber being heated to a temperature above the dew point of the fuel so that it vaporises.
