Patent FR-2512502-A1 (FR)
Inventor: TAKAMI AKIRA
IPC: H02K21/38
Filed: 1982-09-08
Abstract: In an ignition system having a shaft (1), a stator (3), a rotor (2) and a permanent magnet (4) there is a magnetic flux on a path through the stator, rotor and a section of the shaft, an ignition coil producing an ignition signal as a reaction to the change in the magnetic flow as a result of the rotation of the rotor. A short circuit coil (8) wound around the shaft suppresses the occurrence of an interfering magnetic flow so that a satisfactory ignition signal can be produced when this ignition system is used in internal combustion engines.
Patent FR-2514830-A1 (FR)
Inventor: GASKELL DAVID JOHN
IPC: F02M65/00
Filed: 1982-10-19
Abstract: A fuel injection nozzle for delivering fuel to an internal combustion engine contains a valve element (13) which is moved off a seat (15) under the action of the pressurised fuel. The valve element is arranged in a chamber enclosed by an annular wall (24). During operation the chamber contains fuel. A pair of electrodes (31, 32) is mounted on the outer surface of the wall and the capacitive reactance between these varies with the movement of the valve element. The electrodes are connected either directly or via an electrical control circuit to connecting terminals (35, 36) on an enclosing part of the nozzle, the electrical control circuit causing a change in the impedance. The wall is composed of an electrically insulating material.

IPC: F15B5/00
Filed: 1983-05-24
Abstract: The invention relates to a method for converting an electrical quantity into a pneumatic or hydraulic quantity of the type using a pneumatic or hydraulic flow passing through at least one opening. The method consists in fixing a vibrating strip 20, particularly of the piezoelectric type, between a delivering conduit 25 and a receiving conduit 28 so as to enable the said strip to vibrate in front of the openings of these conduits and to successively cover or uncover these openings, and in applying to the said strip the electrical quantity to be converted under conditions suitable for making this strip vibrate with am amplitude which is a function of the said electrical quantity. The delivering conduit 25 is supplied at a constant pressure and the flow received by the receiving conduit 28 ends up being modulated as a function of the electrical quantity; the mean pressure Ps measured at the outlet of this receiving conduit thus represents this electrical quantity.
