Patent FR-2293236-A1 (FR)
Title: Dissolving gas in counter-current liq stream - in column with perforated trays down which liquid flows under gravity
Inventor: SEVIC BOHUMIL
IPC: C02F3/24
Filed: 1974-12-05
Abstract: A gas stream, e.g. oxygen, is dissolved in a liq. stream, e.g. water, in a column in which the water flows down and the gas flows upwards, the liq. stream vol. being 300-1000 times that of the gas stream. Perforated trays divided the column into vertical sections, the liq. being introduced under gravity at the top and leaving at the bottom, with the gas being introduced at the bottom and leaving at the top. On each tray a liq. level is built up, the liq. passing as a jet through the holes in the tray. Gas is transferred from the gaseous phase below one tray to the gaseous phase below the next tray above by a pipe with ends opening out in each of the gaseous phases. The liq. level on a tray is >=5cm. high and the height of the gaseous space a max. of 40 cm. Method is used for dissolving gases in liqs. esp. oxygen in water for aerating waters for aquariums, etc., but also residuary waters and fermentors. Liq. uses its own energy to pass down the column, i.e. under gravity.

Title: Thermostatic valve with reservoir clappers and actuator - has safety device which absorbs fluid dilatation above critical temp.
IPC: G05D23/12
Filed: 1975-01-14
Abstract: The thermostatic valve has a reservoir (7) with rigid, thick walls filled with a liquid, one or more clappers (8, 9) and an actuator for these clappers comprising a first bellows which deforms elastically up to a given temperature under the influence of the dilatation of the liquid. A safety device absorbs dilatation of the fluid above the previously-mentioned temperature and comprises a second bellows with thin, elastically deformable walls. It is connected to the reservoir and mounted inside a region filled with compressed gas. Its walls are initially butted mechanically upon each other under the influence of the compressed gas.
Patent FR-2301420-A1 (FR)
Title: Four-wheeled vehicle braking system - uses three way valve to restrict braking to spinning wheel when immobile
IPC: B60T8/32
Filed: 1975-02-24
Abstract: The four-hweeled vehicle braking system allows at least the two driving wheels to be braked simultaneously. An auxiliary unit is engaged in order to extricate the vehicle if immobile due to one of the driving wheels spinning, by restricting the braking effect solely to the wheel which is spinning. There can be a three-way valve in the hydraulic pipe between servo unit and drums. This normally allows braking fluid to flow to all four drums but it can be so set that the fluid is deliverecd to one of the brake pipes only.
Patent FR-2302277-A1 (FR)
Title: Sodium bi-carbonate prodn. from chloride electrolysis prod. - by continuous 2-stage treatment with carbon dioxide and cooling
Inventor: ARTUR ANDRE
IPC: C01D7/07
Filed: 1975-02-28
Abstract: In the prodn. of NaHCO3 by treating the discharge from an alkali chloride electrolysis cell, esp. a diaphragm cell, with CO2, (a) the Na ions in the discharge are converted to Na2CO3 in a first zone; (b) the resultant Na2CO3 is transferred to a second zone for the formation and pptn. of NaHCO3, in which an exchange between gas and liquid occurs and the solid is discharged; and then (c) the prods. obtd. in the second zone are transferred to a third zone with gas-liquid exchange and discharge of the solid, where NaHCO3 formation is completed and it is cooled. Pref. the max. temp. in the second zone is below 80 degrees C, esp. 40-60 degrees C and the temp. at the outlet from the cooling zone is 45 degrees C or under. Part of the suspension can be removed from at least one point in zone (c) or above this zone and recycled to point(s) above the max. temp. point. The process overcomes the disadvantages caused by the different kinetics of the various reactions, Na2CO3 formation occuring rapidly and almost completely, whereas the other 2 reactions (NaHCO3 formation and pptn.) are slow. A relatively low temp. can be used, esp. with recycling, and the process is suitable for continuous operation.

Title: Overhead conveyor charging and discharging point - has continuous chains carrying two arms with rails between then sloping towards point
Inventor: GERARD JEAN-YVES
IPC: B65G47/57
Filed: 1975-06-25

The rounded end (12) of the arm has a vertical slot (13) at the bottom. A spindle (24) with an ejector foot (25) inside slides through the boss (22).
Patent FR-2276080-A1 (FR)
Title: Removal of sulphur dioxide from gases
Inventor: BECHTHOLD HORST
IPC: B01D53/50
Filed: 1975-06-27
Abstract: Stack gas contaminated by acid fumes, esp. SO2 is purified by a process in which (a) the gas is mixed with concentrated salt soln.derived from the gas itself; (b) the mixt is vapourised, (c) dust and the salt crystals are removed almost completely from the gas; (d) the gas is mixed with a liq. to absorb the acid components and wash out remaining solids, producing the soln. used in step (a); and (e) the gas is vented via a stack.. The sulphur contg. product is sepd. as a dry salt together with dust in step (c) which occurs for example in an electrostatic filter. The salt particles are larger than would be produced by a gas phase reaction and hence more easily sepd. Particles which escape the filter are dissolved later so that the efficiency of the filter is not critical. No regeneration of the absorption media is required. This saves energy and transport costs. No contaminated water needs to be disposed of. As the salts produced are soluble in water no blockage of lines occurs

Title: Rotary motor with star shaped eccentric rotor - has fixed casing with one lobe more than on rotor
IPC: F01C1/10
Filed: 1976-07-09
Abstract: The rotary motor has a star shaped chamber and eccentric rotor. The chamber boundary consists of a number of curves meeting at apices; the rotor- and chamber-surface forms and dimensions are mathematically related so that when the rotor is turned its centre moves in a circle around the centre of the chamber and its apices - one fewer than those of the chamber - mesh in turn with the chamber apices. Also, throughout the rotor's orbit all but one of its apices remain in sliding contact with the chamber surface, and there is a point of rolling contact at the instantaneous centre of rotation. Inside the main chamber a number of smaller chambers are produced whose size varies cyclically.

Title: Drive for large diameter rotating drums - has main roller spindles and guide track formed in rim of driving gear
IPC: F16H57/02
Filed: 1977-01-12
Abstract: The gear wheel rim is attached by the spokes to a large diameter drum. The drum is rotated by the pinion which meshes with the teeth and is mounted in the bearings. The separating force between the pinion and the rim is resisted by the rollers. These rollers run on tracks formed on the inside surface of the wheel rim. Any radial play in the system is taken up by the smaller rollers mounted on the ends of the main roller spindles. This arrangement of rollers avoids the need to transmit the radial force through the structure and reduces bearing wear.
