Patent FR-2474889-A1 (FR)
IPC: C02F3/16
Filed: 1980-02-01
Abstract: The invention provides an aerator device for dispensing liquid in a gas phase by producing an upwardly-directed spray of the liquid from a tank. The device, which is intended to be submerged in a tank, comprises a motor-pump unit in the vicinity of the tank floor and a primary flared tube and a secondary flared tube coaxial therewith. The secondary flared tube is connected to a delivery nozzle by an intermediate duct, and the delivery nozzle is surmounted by an adjustable needle. The buoyancy of the whole assembly is ensured by a set of variably ballasted buoys which pivot at the end of support arms, and by an upper buoy concentric with the nozzle.
Patent FR-2449654-A1 (FR)
IPC: B01D17/02
Filed: 1980-02-06
Abstract: A movable downflow baffle (14) for retaining impurities (12) floating in the vicinity of the surface of the water is arranged in a stormwater tank or clarification tank. The downflow baffle (14) is designed such that it is buoyant and is mounted in the tank (1) such that it can be pivoted between a lower position (14') and an upper position (14''). When the water level is low, it bears with its lower edge (20) on the discharge-side end wall (21) of the tank (1). With rising water, buoyancy pivots it into an upper position releasing the end wall (21). Irrespective of the water level, the pivotable, buoyant downflow baffle prevents impurities from being able to pass into the receiving watercourse.

Title: Printed circuit electronic identification card reader - uses external activation to open shutter to allow card to be drawn in to stop before shutter is closed during processing
Inventor: BASSET JEAN-CLAUDE
IPC: G06K7/00
Filed: 1980-02-28
Abstract: The card reader accepts electronic cards with embedded conductive strips of the type used for personnel identification or financial transactions. Motor driven wheels draw the card into the reader and a stop fixes the position of the card for reading. To enter a card to the reader the user initiates a signal to operate a drive motor which has a cam on its output. A pivoted beam is held against the cam by a spring and rises so the shutter attached to the beam end moves clear of the card slot. When inserted, the card operates a microswitch to start the motor which drives two feed rollers which draw the card in till it reaches an end stop. The feed rollers continue to run and the reaction moves the pivoted arm supporting the top roller to operate a second microswitch turning off the drive motor. The beam falls as the cam completes its rotation, covering the entry slot and allowing a contact block to come into contact with the card so information may be read.

Patent FR-2470335-A1 (FR)
IPC: F23J3/02
Filed: 1980-11-18
Abstract: The device has a cleaning brush (5) which can be raised with the aid of an upper holding and pulling cable (2). A second pulling cable (9) is provided, the length of which reaches to the upper end (10) of the chimney (1) and which at its upper end (11) has a coupling (12) for detachable connection to the underside of the cleaning brush (5). In the rest position, this pulling cable (9) can be uncoupled from the cleaning brush (5) in the bottom region (13) of the chimney (1) and set down there. With the aid of the cables (2, 9), the cleaning brush (5) can be moved up and down, a powerful friction being possible in relation to the chimney walls because the cleaning brush (5) can be pulled both upwards and downwards and thus does not stick.

Title: Electric arc welding appts. - with consumable electrode feed mechanism
Inventor: JUGE DANIEL
IPC: B23K9/12
Filed: 1981-02-24
Abstract: Appts. for guiding and supplying current to a consumable electrode wire in an installation for electric arc welding includes a body of conductive material having two separate branches joined together and passing the full length of the body. The body is connected at one end to the welding plant and the two branches form a wire guide along the length of the body to permit passage of wire from the entry end via a channel in a joining piece, to the exit end . Electrical contact is provided over a certain length between the conductive body and the wire, and a means for regulating the space between the branches is disposed between the two ends of the body. The appts. overcomes the problem of excessive heat build up through the contact points of prior art appts., where rings were used as guides, together with the excessive wear resulting from the high temp.

Title: Disposable centrifugal separator for oil contaminants - has hollow rotor mounted in one chamber defined by shroud and defining second chamber
Inventor: KLINGENBERG JAMES C
IPC: B04B5/00
Filed: 1981-03-02
Abstract: Oil under pressure is admitted to the second chamber through concentrically arranged tubes or spindles and past a low pressure shut-off valve. The oil flows into the first chamber through tangential reaction nozzles in the rotor to cause contaminants to migrate toward the side-wall of the second chamber under the influence of centrifugal force. The shroud and rotor are permanently closed so that the entire assembly may be discarded when a significant amount of contaminants has been deposited on the sidewall of the second chamber. A baffle screen is mounted between the tangential reaction nozzles and an outlet port in the first chamber.
