Patent FR-2273978-A1 (FR)
Title: Disc braking system for automobiles - has axial expansion of discs by causing balls to leave tapered indent locations
Inventor: TURNAUD LUCIEN ANDRE
IPC: F16D65/14
Filed: 1975-06-06
Abstract: The friction braking discs (5, 6) are spline mounted on the wheel axle shaft (1) of an automobile. Metal braking discs (7, 8) are located between the friction discs and are stationary when the brakes are inactive. These discs are radially located by a number of ball bearings (11) located in indents (9, 10) machined into the surface. A hardened guide ring is a good sliding fit within the main brake housing (2) and provides a guide track for the balls. The metal discs are spring loaded (11') into contact with the balls. A cable operated lever arrangement coupled to the brake pedal allows the two metal braking discs (7, 8) to be moved through an arc relative to each other. This relative motion results in the balls partially leaving the indents and forces the discs apart into contact with the friction material discs (5, 6).

Title: Light alloy piston for high speed engines - has steel insert within piston noncontinuous with overlapping ends
Inventor: SCHEUFLER ROLAND
IPC: F02F3/08
Filed: 1975-08-29
Abstract: The piston has a continuous cylindrical wall of light alloy metal on the inside of which is a steel strip (1) forming a ring cast onto the piston wall during manufacture. The hoop stresses in this ring produce forces on the cylinder wall which oppose thermal forces as the engine temperature rises and result in an elastic deformation which maintains the desired small clearance between the piston wall and cylinder. The steel ring (1) is not a continuous piece but has two abutting ends which overlap each other. One of them has a projecting stud (2) which fits into a corresponding recess (3) on the other so that the ends are located and held together with a limited freedom of movement.

Title: Continuous measurement of test piece pickling loss - for determination of optimum conditions by measurement of hydrogen evolution in thermal conductivity detector (OE150976) (NL021176)
IPC: G01N33/20
Filed: 1976-04-29
Abstract: In a process for continuous determination of H2 freed in acids during pickling of metal test pieces, partic. steel, and picling loss, part of a carrier gas of different M.W. from H passes in continuous stream over pickling bath surface containing test piece and gas mixture passes to thermal conductivity detector, while part is supplied direct to detector so that voltage bridge in the detector measures and records voltage curve continuously, such that area under the curve is proportional to pickling loss of test piece.

Patent FR-2310531-A1 (FR)
IPC: C10B7/10
Filed: 1976-05-03
Abstract: In the process for the pyrolysis of polymeric and inorganic waste products, these are predried and, if necessary, precomminuted. The waste products thus pretreated are then heated at subatmospheric pressure to their decomposition temperature by means of an external heat supply and forcibly transported onwards during the heating and decomposition, while the gases released are extracted. At this stage, the decomposition temperature is kept so high between 400 DEG C and 800 DEG C and the subatmospheric pressure is kept so low that the released oils and waxes are extracted. The equipment for carrying out the process contains a reactor pipe (12, 112) in which a driven advancing device (14, 114) is provided and around which a heating device (30, 32, 34, 36) is arranged coaxially. A charging hopper (22) fitted with air exclusion locks (24, 26) is connected air-tight to the charging end, and a discharge chamber (46) sealed air-tight is tightly connected to the reactor pipe at the discharge end, while the discharge chamber itself is connected to the suction side of a fan (64). The process allows continuous operation of this equipment without supplying external energy, while clean, high-value gases are obtained which have a high energy content. Liquid products or sludges can also be processed. The equipment itself is compact and easily transportable.

Patent FR-2333079-A1 (FR)
IPC: D06P3/68
Filed: 1976-11-25
Abstract: Dye preparations for the production of water-insoluble azo dyestuffs on the fibre are described which are employed in the ice colour (azoic dyeing) technique and which contain an aromatic amine from the 2-aminodiphenyl ether series and the halogen-containing aniline series as diazo components in a concentration of 20 to 60 and 20 to 70 % by weight respectively. Ethoxylated castor oils and optionally di-, tri- or tetraethylene glycol monoalkyl ethers are used as solvents for these aromatic amines in the preparations, where the preparations can contain 20 to 80 % by weight of the ethoxylated castor oil and up to 60 % by weight of the ethylene glycol monoalkyl ethers. These novel dyeing preparations are viscous solutions which can be employed in the ice colour technique with a considerable time saving. The diazo solutions obtainable from the preparation are additionally clearly transparent and completely residue-free even after relatively long standing. They also yield uniformly dyed fibre materials having particularly good abrasion fastness when used for dyeing wound packages.
