Patent FR-2137264-A1 (FR)
Title: Centrifugal separator - with by-pass chamber esp for machine tool coolant with swarf
IPC: B04B11/04
Filed: 1971-05-17
Abstract: As the centrifuge chamber becomes filled with swarf the entry to it from the main inlet becomes narrowed and the liquid is diverted through the bypass chamber which forms part of a resonant ultra sonic circuit with sensors which detect falling away from resonance as the liquid in the bypass exceeds a threshold value. These signals are used to actuate an axial door at the base of the centrifuge through which the swarf falls undfer gravity. This door at the same time closes the inlet to the centrifuge proper so that the liquid flows either through the bypass or into a second centrifuge chamber. Automatic self cleaning is achieved.

Title: Decarburising chrome steels by blowing with diluted carbon - monoxide through double/triple feed tuyeres
IPC: C21C5/00
Filed: 1971-07-23
Abstract: Process for decarburising chrome steels esp. stainless steels by blowing the melt with diluted carbon monoxide from tuyeres having double or triple feed. The triple feed comprises an oxidising stream at the centre, a dilutant fed around it and a carbon bearing fluid at the periphery. In the double feed the oxidant and the dilutant are combined. The oxidising stream is industrially pure O2 or a gas contg. O2. The diluent is a neutral gas, argon, steam, etc. The carbon contg. fluid is fuel oil or a mixt of fuel oil/argon/steam.

Title: Mixing plastic or other smelts - as thin cylindrical skin near drum wall
IPC: B29B7/42
Filed: 1972-04-12
Abstract: A method of producing intensive and uniform shear fields, esp. in processing low- to high-viscosity smelts, consists of melting the material into a tubular layer and/or continuously mixing it tangentially and axially so that this layer executes an axially pulsating helical movement. The prefd. appts. comprises strips inside a mixing cylinder, which rotate around the central axis without crossing it, thus sweeping the skin as a mixt around the cylinder wall. The strips are interconnected by oblique discs or rings which provide the pulsating effect. Used esp. for bitumens and tars and ethylene homopolymers and/or copolymers.

Title: Variable drive for car dynamo - using two variable cone gear wheels operated by centrifugal force and torque
IPC: B60K25/00
Filed: 1974-08-09
Abstract: The dynamo is driven from the crankshaft by a belt and pulley system as in a normal vehicle, but coupled to its pulley wheel by two special pulleys, with a second belt drive. The two pulleys are each fitted with conically shaped pulley surfaces, one of which is stationary while the other is moved by centrifugal force. One of the pulleys has its conical surfaces pushed apart by increasing centrifugal force while the other has them moving together. This alters the gearing ratio of the belt drive and, with preset springs etc., the belt drive can be adjusted to give a constant dynamo drive over a wide range of engine speeds.

Title: High yield stripping column for alcoholic solns - with recovery of by-prods. to avoid pollution
IPC: B01D3/14
Filed: 1975-01-03
Abstract: Continuous distn. plant for alcoholic solns., such as weak wines, comprises at least one alcoholic extn. column with an upper inlet for the solns. to be treated. These descend to an overflow and pass via the pipe to a heat exchanger and an outlet for the residuary liquor. Steam is admitted into the column from the boiler which is heated by the coil, traversed by steam under press. In operation, the solns. to be treated enter at, are heated by the exchanger and pass into the extn. column where they are subjected to action of the steam entering at. The prods. in the gaseous phase and rich in alcohol leave at while the residue, stripped of its alcohol, is recovered at the base of column. This is residue is fed by pipe to the boiler while a portion goes through pipes to be recycled to the marc. Residual prods., such as tartrates and glycerol and having a market value, are evacuated by pipe from the base of the boiler. The gaseous prods., rich in alcohol elave the stripping column by pipe and are conc. in column, condensed in, to leave as highly conc. alcohol by pipe. The boiler has a double function; it provides steam for the distn. and also concentrates the fixed, low volatile bodies to produce marketable materials and at the same time prevents pollution.

Title: Circular loom with carriage supporting weft supply - moving on circular track around mandrel to which warp yarns are fed
IPC: D03D37/00
Filed: 1976-01-23
Abstract: Circular loom includes a central mandrel on which the woven hose is produced and which is surround by a track formed of part circular segments. Warp yarns are fed through e.g. guide tubes onto the mandrel through gaps between adjacent arcuate segments of the track. A carriage supporting a weft yarn supply bobbin moves around the track so that the weft yarns guided pref. by an eyelet on the carriage are woven into the warp yarns.
