Patent FR-2233724-A1 (FR)
Title: Electrical plug pin - ease of access to connections by use of secondary pins
IPC: H01R13/193
Filed: 1973-06-15
Abstract: Male connector for one or more pins, permits a certain flexibility by arranging for each such pin to be drilled out to take a further tapered pin to which the electrical connection is made. Such pins may also be drilled out and partially cut along their length to give a sprung contact when mated with a socket. The secondary pins are set in a moulding having side flanges or finger grips to allow them to be push fitted into the mating pins proper. The cable leads can be brought into the interior of the plug by various orthodox means including through a moulding leading to the level of the main pins.

Title: Determining target position above reflecting surface - uses three frequencies in radar with four horn antennae
IPC: G01S13/38
Filed: 1973-09-20
Abstract: A target just above the sea causes an image effect giving rise to erroneous position data. The exact position is determined using different frequencies in a radar with four horn antennas. Three oscillator outputs are amplified and passed through a transmit receive switch to a monopulse radar with four horn antennae. These signals are transmitted separately with a time interval. The three received signals pass through the switch to a sum channel and to two difference signal channels which are then amplified by low noise amplifiers. These signals are filtered and processed to obtain amplitude and phase signals which are digitally processed to give azimuth, elevation, height and range data.

Title: Multi-way rotary plug valve - for transfer of wine from principal tank
IPC: F16K31/05
Filed: 1973-11-13
Abstract: Multi-way valve. partic. intended for the wine-making industry, can be operated from a distance; it allows the transfer of wine from a principal recipient to a no. of separate tanks placed side by side or apart. The body of the valve is fitted with a flange which has four openings which can be brought successively into communication with the inlet, according to the posn. of the lever. The valve plug is turned by an electric motor and reducing gear and its posn. is remote-controlled by a rotary selector. The latter controls the rotation of the pinion; this drives the flywheel through the chain. The flywheel is mounted to idle on the shaft, carrying the lever, and it drives the latter through a knurled-head screw and the short arm. The valve can be operated from a distance with the greatest precision, for transferring the wine as reqd.

Title: Thyristor control for I.C. engine ignition - holds thyristor gate near ground potential during non-conducting state
IPC: H03K17/72
Filed: 1973-11-16
Abstract: The circuit controls the discharge of the capacitor of an internal combustion engine ignition circuit as found in vehicles etc. It aims to overcome the necessity for high power transistors and power dissipating resistors required to overcome problems of thyristor instability and erratic functioning. To this end an npn transistor is connected across the gate - cathode circuit of the thyristor such that during the non-conducting state of the thyristor the gate potential is approximately at earth, i.e. that of the cathode. Initiating switching is by means of a mechanical circuit breaker, one side being earthed, which feeds the transistor via diode, capacitor and resistor circuit and a further npn transistor.

Title: Multi-purpose boiler for hot water or steam - relies entirely on radiation from flame or burning material without convection bundle
IPC: F24H1/26
Filed: 1973-11-26

Title: Energy producing machine using buoyancy forces - has endless chain of curved buckets immersed in water and filled with air
IPC: F03B17/04
Filed: 1975-07-25
Abstract: An endless chain passes round two wheels mounted on shafts one above the other and immersed in a tank of water. An air compressor (H) pumps air through a duct (S) to the bottom of the tank. As the air emerges from the duct (S) it is directed into the inverted buckets (G) attached to the chain. The air expels the water from the buckets (G) and the resultant buoyancy forces them upwards so imparting motion to the chain. The air is spilled out of the buckets as they pass over the top wheel.
