Title: Removing projecting bulges from welds - on the outside or bore of spiral welded steel pipe, using tungsten carbide cutter
Inventor: POTTIER MICHEL ALBERT
IPC: B23D79/02
Filed: 1975-02-07
Abstract: Process for removing a bulge from a welded seam on a surface, in which a roller free to rotate on a shaft is supported on the surface, the roller possessing a sharp, circular edge which attacks the seam, and the shaft is located at a constant distance and orientation w.r.t. the seam, relative motion being applied between the shaft and the surface so the roller removes the bulge. The roller is pref. aligned at the start of the process and the surface then displaced, the pref. use being the dressing of a welded seam formed in the continuous mfr. of steel tube by bending and spiral welding. The cutting roller is made e.g. of tungsten carbide and it can work at ca. 1000 degrees C i.e. immediately after making the weld; the roller is very robust and can remove the weld bulge on 30-40 km of pipe which is 50-100 times the length treatable by a conventional tool.

Patent FR-2338736-A1 (FR)
Title: Sieving process for pptd. particles - with preliminary decantation of liq. to concentrate particles
IPC: B01D21/00
Filed: 1976-01-23
Abstract: Sieving sepn. is intended for use with pptd. particles; by continuous decantation before sieving, only a liq. with a high concn. of particles is fed to the sieve. As applied to recovery of proteins from whey, the raw material is introduced into a tank and is fed by a pump to a heat exchanger, to bring it up to 67 degrees C. In an exchanger it is further heated to 95 degrees C and sufficient acid, from the reservoir, is added to bring the pH up to the pptn. level. Decantation is effected in the cyclone, the liq. being introduced tangentially through a nozzle. Whey with high protein concn. is delivered by a pump, through a pipe, to the sieving device. The whey, after removal of the protein and along with that coming via a pipe from the decanter, goes into a recipient from which it is delivered by pump to one side of the heat exchanger to heat the incoming whey. The sepd. proteins are collected, homogenised and delivered into a recipient as a protein cream. The size of the sieve can be reduced by decanting the liq. first. The process can be operated continuously and is suitable for mfr. of casein, yeasts and pptd. proteins.

Title: Line current inversion detection circuit - incorporates memory circuit and is employed in private telephone exchanges
Inventor: SOULETIE JEAN-JACQUES
IPC: H04Q1/38
Filed: 1976-03-12
Abstract: A circuit detects line current inversions and is employed in a private telephone exchange. The current detection circuit furnishes first and second detection signals as and when the line is supplied with signals moving in respective directions. These are stored in a memory circuit which emits a memory signal of longer duration than the detection signals Two memory circuits (CM1, CM2) may be used. A coincidence detection circuit receives the memory signals and outputs an inversion signal whenever the memory signals coincide. The inversion signals are used to monitor electronically, the beginning and end of each communication whereby system accounting is facilitated.

Patent FR-2319584-A1 (FR)
IPC: D06F39/00
Filed: 1976-07-16
Abstract: In the apparatus connected to a washing machine (1), the hot and the cold waste water are each fed to a collecting tank (6 and 7 respectively). The hot waste water is fed from the associated collecting tank (6) to a heat exchanger (3) by means of a pump (11, 12) and subsequently passes into the waste-water channel (4). The cold waste water passes out of the associated collecting tank (7) by way of a further pump (11', 12') and a filter (10) to the same heat exchanger (3), where it absorbs the heat from the hot waste water. It flows from the heat exchanger (3) to a hot-water collecting vessel (5) which is connected to the washing machine (1). The little-soiled rinsing water can then be used for a subsequent washing process.

Title: Launching unit for clay pigeon shooting - has motor to operate launcher arm, and slipping belt drive to provide random angle of throw
IPC: F41J9/24
Filed: 1976-10-26
Abstract: The launching unit for clay pigeon shooting has a spring operated launcher arm and is also orientated after each launch to provide a random angle of throw. An electric motor drives a crank (19), the crankpin (20) moving the spring (24) out of equilibrium to operate the arm (13) rapidly; a microswitch (32) then stops the motor. Simultaneously, the motor drives a reduction gearbox, the output shaft having a belt and pulley drive onto a crank disc. This operates a ball joint and rod assembly fixed to the unit housing. The belt is permitted to slip, the rotation moving the unit to a random position.

Title: Starch-based flocculating reagent - for flocculating red mud in aq. alkaline aluminate soln.
IPC: C02F1/52
Filed: 1976-12-23
Abstract: Starch-based reagent is prepd. for flocculation of solids suspended in aq. alkaline aluminate soln. which are formed in treatment of bauxite by the Bayer process. Method comprises subjecting starch in an aq. suspension in presence of 1-3 wt.% Na tetraborate and 3-30 wt.% water soluble Mg salt calculated as water free salt referred to starch, to a simultaneous heating and drying treatment. The reagent has improved flocculating properties and is used for the flocculation of red mud formed when treating bauxite with aq. alkaline soln. according to the Bayer process. Flocculation of red mud is effected with a smaller quantity of starch than the known starch based reagents, which is desirable since the liquor, after sepn. of red mud and pptn. of alumina hydrate, is recycled to the Bayer process.

Title: Heat exchanger for car heater - has two connected heating elements with edge strips for variable mounting and sleeve for forming separate chambers
IPC: F28D7/10
Filed: 1977-06-08
Abstract: The heat exchanger heats the air for the passenger compartment of a car using the heat from the exhaust pipe of an I.C. engine. The heat exchanger has a heater body (Ce, and the air to be heated flows around it. The body consists of two connected elements (3a, b), fastened to each other along a plane (P), and forming an internal channel (4) for the hot exhaust gas.
