Patent FR-2260374-A1 (FR)
Title: Jet agitator for liqs - with alternating rotation partic useful in photographic processing
IPC: B01F33/40
Filed: 1974-02-13
Abstract: An agitator for stirring a liq. in a vessel by means of jets of fluid, either gaseous or liq., has two jets and a deflector. The deflector is mounted so that it can pivot freely and mask either of the jets alternately. When the deflector masks one of the jets, the other jet causes the liq. in the vessel to rotate in one direction. The pressure of the rotating liq. ont he deflector causes it to turn on its pivot, opening the jet that was masked and masking the other one. The liq. is then caused to rotate in the opposite direction, repeating the process. The liq. is thus agitated by rotation in opposite directions alternately. Device is used for e.g. agitating liqs. during the processing and washing operations in photography, or in treating other sensitive surfaces. The agitator permits, by simple and effective means, the alternating rotation of a liq. in a vessel, and is more effective than existing agitators with jets which cause the liq. to rotate in only one direction.

Chamber (II) is pref. connected to a pump so the vacuum in the bore of the tube is the same as in chamber (I). Chamber (II) is pref. identical to chamber (I) so that both ends of the long tube can be simultaneously welded. Suitable for welding plugs in the ends of long tubes used to hold fertile or fissile material, i.e. fuel rods.

Title: Steelworks reheating furnaces for slabs - using both blast furnace gas and induction heating to reduce consumption of fuel
Inventor: BORGNAT DANIEL
IPC: C21D1/34
Filed: 1974-09-11
Abstract: Process for heating iron and steelworks products, in which during a first period, the products are heated in a furnace employing flames at a temp. below the rolling temp. and the products are then transferred into an electric furnace for heating up to the desired rolling temp. during a second heating period. The first period pref. consists of heating semi-finished products up to the Curie point. followed by heating to the rolling temp. in an induction furnace. One pref. furnace consists of a walking beam furnace with two heating chambers, one using flames, the other induction heating. Used to reduce the amt. of petroleum fuels currently employed in reheating furnaces by the combined use of inexpensive gas produced in the steelworks e.g. coke oven or blast furnace gas, the induction heating reduces oxidn. decarburisation and environmental pollution.

Title: Spring mounting for disc brake - has spring between saddle and carrier plate to prevent rattling
Inventor: GERARD JEAN-LOUIS
IPC: F16D55/224
Filed: 1974-10-25
Abstract: The brake saddle carries a brake operating mechanism, which presses at least one friction plate against a rotating disc. The friction plate consists of a carrier plate on which a friction pad is mounted. The carrier plate moves along guide faces on the brake saddle. A spring acts between the saddle and the carrier plate, and prevents the carrier plate rattling. The spring can be locked axially w.r.t. the carrier plate. The first section of the spring passes through an opening in the carrier plate and engages, with a locking clip, with a second part of the spring. The spring together with the friction plate form an assembly which can be removed from the brake in one unit.

Title: Electronic car antitheft alarm - has three time delay circuits operated by door pillar switches with alarm isolating ignition coil and activating horn and lights
IPC: G08B13/22
Filed: 1975-07-10
Abstract: The electronic car alarm uses three time delay circuits. The first is brought into operation by a door pillar switch which allows the driver 30 secs. to open the car doors without activating the alarm. A second delay then allows 10 secs. in which to switch on the car ignition when the car doors have been closed.
