Title: Pulley for automobile V-belt - has channel formed by bent radial tabs on periphery of a disc
IPC: F16H55/44
Filed: 1974-01-08

Title: Oil slick removal ship - has holes in sides of hull for entry of oil and water into sepg. tanks
IPC: E02B15/10
Filed: 1976-03-02
Abstract: A ship for removing a large oil slick has holes in the sides of the hull, at water level through which the mixture of oil and sea water enters a set of water fillers tanks. From there, clean water can be emptied in stages, to be eventually replaced by the oil collected, as it separates from the sea water. The oil and water flowing in displaces clean sea water from tank to tank as it travels around divider plates at various heights sepg. the tanks. Finally, the recovered oil is passed into a main central tank. A device to gauge the depth of the oil slick may be used.
Patent FR-2345249-A1 (FR)
Title: Ingot casting procedure - in electroslag furnace without forming deep molten metal cores
IPC: B22D23/10
Filed: 1976-03-26
Abstract: A number of ingots are cast in a furnace comprising a main mould section, in direct open communication with a number of ingot mould sections having a total cross-sectional area less than the main mould section cross-sectional area, an electrode, and a conductor disposed outside the ingot mould sections. A pool of molten metal is formed in the main mould section and maintained by directing an electrical current through the electrode and conductor. Molten metal flows from the pool into the ingot mould sections and is prevented from freezing at the interface between the main mould section and the ingot mould sections. Current is prevented from entering the molten metal in the ingot mould sections. The method is used to cast a number of ingots from a pool of molten metal without the formation of deep molten metal cores in the ingots. Ingots of satisfactory metallurgical quality can be cast at increased solidification rates, resulting in more efficient furnace utilization and decreased production costs.

Title: Temp. drift compensation for electronic thermostat - uses power dissipated in a triac to produce correction voltage
Inventor: COULMANCE JEAN-PIERRE
IPC: G05D23/24
Filed: 1976-04-26
Abstract: The temperature drift conformation is for a heating system regulated by mean of an electronic thermostat. The thermostat uses a differential amplifier (11). To the inputs of the amplifier are applied a fixed reference voltage and a variable voltage respectively. A ramp voltage is superimposed on one or other of the two aforementioned voltages. The output of the differential amplifier is coupled (11) by an amplifier (16) to a semiconductor switch (4). This switch is in (4) series with the heating system (1). A correction voltage sensibly proportional to the cyclic supply auto off relationship of the semiconductor which (4) is applied to one of the inputs of the differential amplifier (11). This connection voltage is obtained from the magnitude of the power dissipated in the semiconductor switch.
