Patent FR-2067353-A1 (FR)
Title: Metal refining
IPC: C21C5/34
Filed: 1970-11-13
Abstract: Oxygen or oxygen-rich gas admitted to the bottom of a converter through a jet is shielded by a concentric annular jet of protective gas such as a fluid dissociable endothermically, e.g., a hydrocarbon. The protective gas comes from a tank through an evaporator and then through a superheater and/or at least one duct having means of heating. Advantageously the superheating is regulated to give the required gas pressure at the annular jet. The regulation may be automatic in response to the pressure variation. Heating of the conduit may be regulated to a desired temp. The regulation may be automatic in response to variations in the ambient temp.

Title: Sampling appts. with air-purged tubes - for liqs. with or without solids
IPC: G01N1/14
Filed: 1974-02-01
Abstract: Sampling appts. is for taking measured samples of liqs., which opt. contain solids; it comprises a closed measuring chamber mounted in the upper section of an envelope. The chamber has a cylindrical wall, pref. of transparent material, with graduation markings at intervals of 100 cm3. A vol. control tube passes through the cover and is adjustable vertically to different positions from the base. When a sample is to be taken, press. is applied to the chamber for, say, 60 secs. to clear the chamber and tubes by blowing air through the system. Suction is then applied to draw liq. through the tube and the control tube for 60 secs. until the liq. reaches the electrodes and stops the suction. Press. is then applied for 5 secs. and pushes the liq. out of tube until the level reaches the lower end of this tube. A pinch valve is opened and the air pushes the liq. out of the chamber through a tube into the recipient. This operation lasts for 5 secs. and the press. is cut off by a cyclic timing device. Appts. can be used with liqs. contg. solids because the tubes can be cleared by an air-blowing cycle. A precise vol. of sample is delivered each time it operates even if solids in the liq. cause numerous blockings.

Title: Collective pitch control device for helicopters - primary and secondary compensators for manual control
IPC: B64C27/78
Filed: 1974-02-25
Abstract: When a helicopter is in flight near the ground, the pilot may act upon the blade pitch and carry out corrections different to those which would be carried out by compensators, but when at altitude the pilot may safely abandon manual control in favour of automatic control by the compensators. These improvements are due to (1) a compensator actuator in which a hole is bored through the piston causing a loss in the force acting upon the piston which is connected to the manual control (2). A manual collective pitch control for both main and tail rotors, not dependent upon the aircraft engines (3). Primary compensators for assisting manual collective pitch control of the main rotor and secondary compensators for assisting manual tail rotor collective pitch control of the main rotor and secondary compensators for assisting manual tail rotor collective pitch control, both being sensitive to the pressure of a fluid from a pump driven by the helicopter engine.

Title: Quasi continuous filter with cells on endless belt - having quick release couplings to suction manifold
IPC: B01D33/00
Filed: 1974-12-20
Abstract: Quasi continuous filter consists of a series of filter cells at the base of which is a filter membrane mounted on an endless belt driven by motor. This is designed to move the cells forward in stages and not continuously, each stage as shown having two cells, through this member is not fixed. Slurry is fed to the cells which at this stage are connected to vacuum pumps via catchpots. The cells are then moved to a straight filtration stage while followed by cascaded wash stages, radiant drying. Prod. is finally dumped onto a conveyor belt and the cells are inverted when passing to the under rim of the belt. The cells are washed out before returning to the loading posn. For all filtration operations where filter cake is desired product. The use of the quasi continuous system avoids the need for moving seals. The quasi-continuous principle can also be applied to pressure filtration.
