The invention relates to devices for monitoring radiations employed in X-ray apparatus using cassettes of the screen/film type. The invention resides in the fact that the detector of the radiation monitoring device is not a detector of the X-radiation which has passed through the object to be examined, but a detector 25 of the light emitted by the screen 24 which converts the X-radiation into ligh...

A shredding device uses a plurality of interleaving, counter-rotating discs (16,18) to reduce sheets of material into longitudinal strips. One or more notches (38), formed in the periphery of each disc, cut the longitudinal strips into segments. Deflectors (48,50) disposed in the spaces between each disc clear unwanted material from between the discs. When jammed, the rotation of the discs reverse...

PURPOSE:To easily produce a large amt. of a high activity catalyst for liquefaction of coal by bringing a gas contg. hydrogen sulfide into contact with a goethite slurry, drying the resulting iron sulfide and crushing it into fine particles. CONSTITUTION:Ferrous sulfate or ferrous chloride as starting material in an alkali soln. is allowed to react with a gas contg. oxygen introduced into the soln...

An improved process for controlling desired product distribution in fluidized catalytic cracking of olefins is provided wherein riser reactor temperature profiles are controlled by means of atomized quench streams provided downstream of the hydrocarbon feedstock charge level.

Process for sweetening a petroleum cut by catalytic oxidation, in a stationary bed, of the mercaptans which it contains. According to the invention the oxidation reaction is carried out in the absence of aqueous phase and in the presence of an oxidising agent, and the molecules of water which are formed during the said oxidation reaction are removed from the catalyst support by periodically w...

PURPOSE:To accurately determine presence or absence of quenching of a coil by drawing a condition that an error mode of a numeric value solution is not amplified even if a timing step is advanced as a method of simultaneously satisfying a fluid equation and a heat conduction equation, and obtaining temperature distribution of a conductor in spatial and timing manner, and setting a timing division ...

PURPOSE: To prevent the deterioration in the properties of concd. juice by using a selective permeable membrane which comprises a polymer insoluble in water and of which part or the whole of the carboxyl groups form salts at the concentration of a saccharides-contg. aq. soln. CONSTITUTION: The aq. soln. to be concd. is held at a specified temp. by a heat medium in an overcoat 6 within a hermetic c...

An automatic braking control system is capable of automatically maintaining a braking force once a vehicle has been stopped by the driver. The braking force is maintained until the clutch of the vehicle is engaged, at which time the force is automatically released so that the vehicle can be restarted. This system is especially useful for restarting a vehicle which has been stopped on an upward slo...

Un procédé de préparation des particules de résine à capacité d'absorption d'eau élevée consistant à mélanger une poudre d'une résine à capacité d'absorption d'eau élevée avec une solution d'un agent surfactant du type sorbitanne ayant un HLB de 2,1 à 5,0 dissous dans un solvant organique, à volatiliser le solvant organique du mélange pour donner une poudre de résine ayant une teneur en solvant...

The invention relates to a novel heat-stable syntactic foam comprising hollow microspheres and a binder, characterised in that the binder is based on a polystyrylpyridine or polystyrylpyrazine resin. The microspheres are made of glass, silica, ceramic or a synthetic material. The foam is prepared by dispersing the microspheres in the resin and hardening the whole by baking. A pre-bake may be carri...

L'invention concerne un procédé et un dispositif pour l'inspection acoustique d'un sondage dans lequel on forme un ou plusieurs signaux représentatifs respectivement d'une ou plusieurs informations relatives audit tubage et aux matériaux qui l'environnent, à partir d'un signal acoustique de réflexion S(t) obtenu à la suite de l'envoi, à travers le fluide présent à l'intérieur du tubage d'une im...
