Abstract: A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 650 DEG  F. plus material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalent of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow-type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 DEG  to about 1400 DEG  F., and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight. The spent, coke-laden catalyst is separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen. The regenerated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil. A portion of the catalyst is withdrawn from the cycle, passed through a magnetic field to separate the mass of catalyst into high activity catalyst and low activity catalyst, returning the high activity catalyst to the cycle and disposing of the low activity catalyst.

Abstract: In a document processing system a printer (22) prints a document (14) identification number in the form of a bar code including a sequential portion in the form of a number identifying the particular document (14) and a non-sequential portion which may contain common information. The sequential portion is formed by a number provided by a pseudo-random number generator. The pseudo-random identifying numbers of documents (14) being processed are stored in a storage file (106). When the bar code is read, erroneous read-outs are corrected if possible in an error detect and correct circuit (102). If the read-out number is not correctable it is compared with numbers from a region of numbers in the storage file (106) including the location of the expected number. A comparison is regarded as positive is the read-out digits correspond with a compared number from the storage file (106) to within a predetermined threshold. The system has improved document misread and reject performance and hence a high reliability.

Abstract: Disclosed is a radiant energy optoelectronic position monitor system which detects the angular position of a "galvanometer mirror" (beam scanner) (gm) used in an optical disk memory arrangement. 
     Using a single infra-red monitor beam, angular motion is converted to linear displacement of an image on a detector cell (31) so as to produce a corresponding electrical signal. This. signal is presented to a processing circuit with an analog divid- er to normalize output scale factor. The result is a high gain electrical circuit for recovering output signals in an environment with strong magnetic interference. 
     Such a position sensor is described as especially apt for use in a "three beam" laser optical system comprising a writing beam and two reading beams all incident on the same track of a rotating disk optical recording medium. One of these reading beams is incident on the track ahead of the writing beam so as to serve as a "read-before-write" beam, while the other reading beam is incident on the track behind the recording beam so as to serve as a "read-after-write" beam.

Abstract: The invention provides an efficient and economical means for indexing products from a continuously moving chain conveyor to a stationary position for robotic operations and then returning the product to the moving chain conveyor. Indexing is achieved by a moveable shuttle carriage which is propelled along the axis of a main drive shaft through the engagement of a follower, located beneath the shuttle carriage, with a helical recess in the circumference of the shaft. Controlled acceleration, deceleration and positioning are accomplished by varying the rotational speed of a uniform helical drive shaft or by the use of a variable helical drive shaft rotated at constant speed. The shuttle carriage picks up a product carrier by engagement of a drive dog with the carrier to propel the carriage and carrier in unison to an operating station along tracks in parallelism with the axis of the shaft. Several indexing units may be employed in tandem to provide accumulation of products and to transfer each product back to the moving conveyor after the operation has been performed.

Abstract: Transducteur électroacoustique muni d'un diaphragme (12) se composant d'une feuille plissée (34A) et d'une mince feuille plate (32). La feuille plissée possède une pluralité de conducteurs (36, 39) dans des éléments en saillie s'étendant vers l'arrière (P) et la feuille (32) est fixée à la surface antérieure plate (29) de la feuille plissée (34A). Dans les diaphragmes conventionnels, les ondulations de la feuille ne sont pas fixées entre elles et forment une structure peu solide avec une surface antérieure irrégulière qui empêche les ondes sonores rayonnées par la surface d'être en phase. La feuille antérieure du diaphragme (12) le rigidifie de sorte que la feuille plissée (34A) reste plane et les éléments en saillie (P) restent en alignement avec les pièces polaires (44, 46) de l'assemblage d'aimants (14). Afin d'obtenir une bonne réponse en fréquence et l'impédance désirée, il faut utiliser davantage de conducteurs que ceux utilisés dans les diaphragmes conventionnels. Les conducteurs (36, 39) de la présente invention sont déposés sur une ébauche (34) directement l'un en face de l'autre de sorte que l'ébauche peut être aisément pliée sans fléchir ou être déformée d'une manière quelconque. En outre, lorsque le diaphragme (12) est en oscillation, de l'air est amené de force autour des conducteurs (36, 39) et ventilé au travers des entrefers dans l'assemblage d'aimants (14), réduisant ainsi toute accumulation de chaleur.
