Patent FR-2344183-A1 (FR)
Title: IC engine ignition command system - uses storing of voltages as functions of peak values in dependence on various parameters
IPC: G06G7/30
Filed: 1976-03-11
Abstract: The command signal appears with a phase shift in relation to the instant of a periodic information signal reception. During each period voltages, which are functions of the peak value of the voltage generated during a previous period, are stored. The stored voltages are set to zero during a preset time calculated from the instant of the previous voltage resetting to zero. Further voltages are generated as periodic functions of time not exceeding the previous voltage period. The stored voltages and the additional voltages are compared in pairs, and a coincidence signal is generated with a phase shift. A synchronous signal is allocated to the phase-shifted signal. One signal of this group is selected to trigger the command signal.

Title: Two stage coke oven charging system - charging extreme end piles of one and centre pile of preceding chamber
Inventor: FIDCHUNOV LEONID NIKOLAEVICH
IPC: C10B31/04
Filed: 1976-03-12
Abstract: Coke ovens of the horizontal chamber type are charged from a coal charging car in two stages. In the first stage, coal is charged into a chamber through the charging holes at the two extreme ends (pusher side and coke side) to form two conical piles. In the second stage, the space between these piles is filled by a conical pile from the central charging hole when the coal charging car is in the position to charge the extreme ends of the next chamber. This reduces the overall time required for the coal charging operation. The conditions for the circulation of the charging fumes are improved. Levelling and compacting of the coal charge are facilitated.

Title: Fuel cell electrode - consisting of three thin layers, giving less weight and improved performance
Inventor: BONO PIERRE
IPC: H01M4/86
Filed: 1976-03-16
Abstract: Fuel-cell electrode consists of (I) an active layer, (II) a hydrophobic layer, (III) a porous layer and (IV) a carbon fabric enclosed in layer (I). Layer (Ie ensures reaction at its level of one of the reactants in the presence of the electrolyte. Layer (II) is immediately underneath layer (I), and has predetermined hydrophobicity and porosity so as to permit the reactant to reach layer (I) while avoiding passage of the electrolyte. It also has sufficient electronic conductivity to lead away the electrons resulting from the reaction. Layer (III) is beneath the hydrophobic layer and has sufficient conductivity to remove the electrons. The surface of this layer not in contact with the hydrophobic layer is fed with reactants. The electrode is thin, light, and exhibits improved electrical characteristics.

Title: Time and date transmission system - using radio waves with repeaters spaced over required reception zone
IPC: G04G9/00
Filed: 1976-05-24
Abstract: The transmission system employs radio waves to transmit the official time and the date throughout a given region, using an FM transmitter and a number of repeaters, spaced over the reception zone. A single master clock, e.g a quartz clock is used to supply the time signal to the FM transmitter and each receiver extracts the time signal and supplies it to a slave clock via a two-wire line. A community antenna receiving the FM transmission may be coupled to a single amplifier with an amplification level dependent on the number of slave clocks to be supplied.
