Title: Corrugated formwork for concrete stairs - has dihedral corrugations with horizontal and inclined sections supported by stringers
IPC: E04G13/06
Filed: 1975-09-16
Abstract: The shuttering for reinforced concrete stairs uses dihedral corrugated panels in which alternate corrugations are flat (9) and inclined (10). There are two dihedral sections to each stair tread and by overlapping the horizontal sections of the panels, the shuttering can be made to follow the path of a spiral staircase. For a rotating staircase, the axis of rotation of the panels is determined by a helical stringer. For straight section of stair, the stringer is straight. Using corrugated shuttering, the volume of concrete used is less than with flat panels and the inconvenience of using stair shaped shuttering with complicated reinforcement is avoided.

Title: Fuel injection system for IC engine - has pressure intensifier piston controlled by electromagnetic valve to avoid pressure hammer
Inventor: JOURDE JEAN-PIERRE
IPC: F02M59/10
Filed: 1976-07-12
Abstract: The fuel injection system for an internal combustion engine has a pump (1) supplying fuel through a three-way electro-magnetic valve (4) to a pressure intensifier (10). At the beginning of the injection cycle the line (4a) is connected to the line (4b) so that fuel flows into the chamber (15) and lifts the piston (11). At the same time fuel also flows through non-return valves (3, 6) and lifts the piston (9) to its upper position. A transducer (17) then transmits a signal which opens the line (4c) of the electrol-magnetic valve (4) so that fuel flows into the upper part (18) of the cylinder (10) forcing the pistons (11, 9) downwards. This action intensifies the pressure of the fuel flowing to the injector (12) in the ratio of the areas of the pistons (9, 11) but avoid pressure hammer in the pipe (13).
