Patent FR-2096821-A1 (FR)
Title: Gas washing process - using flow to entrain liquid and centrifugal motion to separate it
IPC: B04C3/00
Filed: 1970-07-02
Abstract: Method uses a cylindrical fitting with a number of tangential gas inlet slots around its lower cylindrical wall and similar tangential gas outlet slots around the upper cylindrical wall, the upper end being closed and the lower end open. Gas enters the lower end and entrains liquid up the inner face of the wall by its high-speed motion; the vortex effect of the gas atomizes the liquid, which is conveyed up the wall towards the outlet slots; as the gas leaves the outlet slots, the centrifugal effect separates the liquid droplets containing the impurities. The preferred appts. comprises a number of such stages successively above one another upwards, the inlet for the as being at the bottom and, the outlet, into a separation chamber, at the top. An outer cylindrical container surrounds all the intermediate stages, the outlet zone of the first stage and the inlet zone of the last stage, thus constraining the flow from one stage to the next.

Title: Delivery tap and level indicator for tank - axially moving sleeve may be used to empty indicator to prevent stagnation
IPC: F16K11/20
Filed: 1973-04-18
Abstract: A description of the construction and operation of a storage tank tap is given. The tap has two functions, the first of which is to enable the vertical liquid level sight glass to be either filled or emptied, the second of which is to enable some of the liquid to be drawn off independently of the first function. In isolating the level sight tube from the tank contents the tube is automatically emptied thus eliminating the possibility of stagnation and bacterial growth within it. The tap has an axially moving ring controlled by a threaded spindle.

The first interval of each pulse train has a duration t1 or t2 to denote the direction in which the adjustment or turning is to be made, and the following N pulses each corresponding to one of the operating parameters or channels, have a duration t1 or t2 indicating whether or not a respective control order is present.
Patent FR-2268711-A1 (FR)
Title: Transparent plastic package - has two shells pressed together and cardboard frame round edges
IPC: B65D75/22
Filed: 1974-04-25
Abstract: The transparent plastic package has two shells (1, 2) pressed together, bringing their extended edges (3, 4) into contact. The shells are shaped (6, 7) so that they can be elastically fitted together. They are hinged together at one side (5). A cardboard frame made froma folded sheet (9, 10) encloses the edges (3, 4). These two sheets are fixed together (12) through holes (11) in the extended edges of the shells. The frame must therefore be broken before the package can be opened. The cardboard can be joined in a number of ways, in particular by using a plastic coating softened by heat.

Patent FR-2242682-A1 (FR)
Title: Method of detecting water in hydraulic oil - measures permittivity using liquids as capacitor dielectric
IPC: G01N27/22
Filed: 1974-05-17
Abstract: The presence of one fluid in another fluid is effected by measuring the variation of permittivity of a sample with respect to a reference. A detector circuit comprises a capacitor (1) immersed in a container (2) containing a hydraulic oil sample. An inductor (6) is connected across the capacitor and to one side (4) is connected an alternating current generator (7). To the other side is connected a potentiometer (9) whose slider (10) is connected to an amplifier (12). In the absence of water in the oil the capacitor and inductor form a circuit in resonance with the generator frequency while the presence of water will cause an increase in current through the potentiometer and thus an output from the amplifier to an alarm.

Title: High or low frequency sound insulation panel - has glass panel in edge mastic in a concrete frame
IPC: E04B1/84
Filed: 1974-05-22
Abstract: The panel which gives improved sound insulation is intended for use in the building industry. A typical panel consists basically of a glass sheet (1) mounted in a concrete frame (2) and fixed securely by means of putty (3). The panel is made of transparent soda-lime glass 8mm thick with a natural curve. This basic design is particularly useful where low frequency sounds are to be excluded (i.e. 400 Hz or less). The design can be adapted for use in higher frequency areas by adding one or more layers of a plastic substance to the glass panel. There may be two sheets separated by a synthetic layer (8).

Title: Machine for harvesting grapes - operators cut grapes from vines projecting between collection belts
IPC: A01D46/24
Filed: 1974-12-18
Abstract: The machine consists of a wheeled frame (1) driven by its own internal combustion engine (8).
