Patent FR-2262198-A1 (FR)
Title: Electronic engine fuel injection system - additional correction circuit to modify duration of injection period
IPC: F02D41/24
Filed: 1974-02-22
Abstract: The main circuit consists of three computers which count N1, N2 and N3 impulses respectively. The time taken by the three computers to count a given number of impulses determines the time of the injection period. This time can be adjusted to suit variable supplementary requirements of the engine by the addition of a correction circuit between the gate and the junction point with the main circuit. This correction circuit compares input information, which is in analogue form, with a predetermined value, and if it exceeds this value, an additional impulse is transmitted to the computer which controls the time interval for the transmission of a signal from an output connection to terminate injection.

Title: Counter-current heat exchanger - with tubes formed from synthetic material sheets, welded along lines giving large capacity economically
IPC: F28D9/00
Filed: 1974-10-30
Abstract: A heat exchanger for transferring heat between two liquids flowing countercurrent to one another has a tube bundle formed by a number of deformable envelopes each one being made from two sheets of synthetic material joined together along a number of horizontal lines, forming flow channels between the lines. The envelopes are stretched and supported parallel to one another in a vessel which constitutes the shell, through which the other liquid flows. The envelopes are kept parallel and regularly spaced by some of the channels being larger than the others and touching the corresp. enlargements in the adjacent envelopes. The shell has gutters and deflectors which impart a helicoidal flow to the shell-side liquid. The exchanger may be made in very large sizes, having large capacities, at a low cost because of the low cost of the envelopes forming the tubes. Construction is simple.
