Abstract: Abstract A process for hydrocracking hydrocarbons for residuum conversion in the presence of a fluidized catalyst, which is characterized by extracting at least part of the fluidized catalyst from the reaction system as a spent catalyst,subjecting at least part of the spent catalyst to hydrotreatment for solubilizing toluene-insoluble carbonaceous materials deposited on the catalyst thereby regenerating the spent catalyst, and recycling the regenerated catalyst to the hydrocracking step.          According to this process, the spent catalyst is recycled to the hydrocracking step in a highly activated state after the regenerative hydrotreatment, so that it becomes possible to suppress the coke production within the reactor to a considerable degree, to maintain the coke level of the catalyst below a predetermined value and to preclude the contamination of the reactor walls with coke.  The process of the invention which regenerates the spent catalyst by a hydrotreatment, in contrast to the conventional catalyst regeneration by oxidative roasting, eliminates all the difficult problems as encountered in the oxidative roasting methods.

Abstract: ABSTRACT            The invention allows the refractive index profile of an optical fibre or optical fibre preform to be obtained by phase difference measurements.  A Zeeman effect laser generates a light beam of plane waves comprising two radiations with slightly different frequencies.  The beam is split into its component radiations and the beats between the first radiation, which is made to follow a path outside the fibre or preform, and the second radia-tion, which is made to follow a path intersecting the fibre or preform, and is also subjected to phase shifts complementary to those produced by a reference fibre or preform, are generated in a photodetector;  the phase differences between said beats and a reference beat are measured, and the refractive index profile compared to that of the reference fibre or preform is obtained from the phase difference  values by suitable computing means.

Abstract: PREPARATION OF A FROZEN FOOD PRODUCT FOR LATER USE                 ABSTRACT OF THE DISCLOSURE A mixture of food pieces are first cooked. After the free water has been removed from the precooked food, leaving voids in the food mass, the food mass is agitated and the surfaces of the food pieces are treated so as to be partially frozen to thereby:  (a) hold the basic shape of each piece without major deformation during agitation, and (b) leave a small amount of unfrozen moisture on the surface of each piece   Dry powdered uncooked adjuvant is then added to the food mass and, during further agitation, comes in contact with the partially frozen surface of each piece and is caused to adhere thereto by the attraction of the remaining moisture, causing a uniform coating of adjuvant to be applied to the food pieces.  The resulting product is then fully frozen for deep freeze storage in a large container.  Due to the uniform distribution of adjuvant throughout the food mass, subsequent reconstituting of any part thereof, or all of it at once, by the addition of free water and heat, will result in edible dishes which have the same basic proportions of ingredients. The food mass and the subsequently added adjuvant may be agitated by tumbling in a drum into which is intro-duced expanding CO2 gas to provide the freezing function. The gas may be used to assist the introduction of adjuvant into the drum from an adjuvant storage hopper having a distributor at its lower end.

Abstract: ABSTRACT      Designed tailormade nonequilibrium synthetic disordered materials are provided containing non-periodically distributed local environments whose position and type are controlled to obtain specif-ic properties which can be coupled or decoupled one from another and collectively from the con straints implied by an ordered structure.  Atoms or groups of atoms can be placed in the matrix in specific designed positions to compensate the spins to obtain unusual physical and chemical properties.  The compositional variation which produces the required nonequilibrium "multi-dis-ordered" materials is accomplished by selectively depositing desired atoms and groups of atoms into designed locations to permit the construction of a true three-dimensionally engineered material.          Where order is an engineering need, it can be de-signed in a local scale or interspersed in varying amounts including layers through the material to create new material functions.    The materials encompass materials which can include non-epitaxial crystalline layers A and B, homogeneous in the x and y directions, but which are randomly or nonperiodically but specifically spaced in the z direction.  Further, the materials include any combination of layers in a non-epi-taxial, non-superlattice structure, such as poly-crystalline or amorphous layers interleaved with crystalline or noncrystalline layers.  Further, included are non-epitaxially grown material struc-tures containing columns or groups of atoms which can be arranged periodically and isotropically.  Many deposition techniques can be utilized singu-larly or in combination with a variety of activa-tion techniques to construct the materials, which include sputtering, electrochemical, laser, ion beam, thermal evaporation, chemical vapor deposi-tion or glow discharge (plasma) techniques.  Other excitation processes also can be combined with the above techniques.
