Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a television strobe effects system in which position information representing the position of a moving object included in a television picture is extracted either from the input video signal or from a sample-to-sample comparison be-tween every two successive frames or fields of the input video signal.  The write-in of the input video signal in a one-frame or one-field picture memory is controlled in response to the position information so that the write-in for each frame of the input video signal is prohibited at those addresses of the memory which correspond to the position of the moving objects.  This permits the signal segment representative of the moving object to replace, for each frame, the input video signal segment at the corresponding addresses of the picture memory, while allowing other portions of the input video signal to be stored in the memory unaltered.  When successively read out at a standard tele-vision scanning rate, the picture memory provides a video signal including in each frame the moving-object-representing signal segment, thereby giving the desired strobe effect.  In contrast to the conventional system of this kind, which has a memory for the frame-to-frame difference signal separated from the picture memory, the present invention requires only one picture memory, with the difference signal being used only for the extraction of the position information.

Abstract: ABSTRACT OF THE DISCLOSURE         A PRI (pulse repetition interval) autocorrelator that functions as a data analyzer for recognition of PRIs in a data set composed of time ordered TOA (time or arrival) words representing the time of reception of a plurality of pulses from a plurality of emitters.  The processing of a data set is performed at each of a plurality of cells of a plurality of coarse map intervals or octaves by adding an incremental assumed periodicity ? to the time of arrival and performing an autocorrelation comparison of the data set for each cell.  As ? increases integrally, octaves are formed by the autocorrelation process and in the illustrated system, eight octaves are sequentially examined, each including 8 cells.  For the autocorrelation of each cell, the TOA words are compared with a double matching process and the correlation counts are developed for each cell of an octave.  An amplitude ordered list is then formed of the cell correlation counts which are greater than a threshold and subcells of each cell on the list are subject to a fine level autocorrelation.  Upon determining the presence of an emitter above a threshold in a subcell at the fine level, the PRI is known to be equal to the symbol utilized for correla-tion of that subcell.  The system then enters a deletion mode to flag or delete the TOA words that matched in that subcell.  Upon completion of the deletion mode at the fine level, the process is repeated at the coarse level to form a new coarse level list of possible emitters.  The operation proceeds until all octaves have been processed for the presence of emitter and in the illustrated system the opera-tion is repeated on a new data set gathered at different angles and frequencies.

Abstract: 47,995 ABSTRACT OF THE DISCLOSURE         This invention is a system of automatically clas-sifying defects both for sorting defective products (metal-lic surfaces, especially tube surfaces) as to the reworking operation required for correcting the defect, and for clas-sifying the defect as to the preceding manufacturing opera-tion which is the most probable cause of that defect and sending a signal to that operation to provide for adjust-ments to minimize future defects.  The system uses a source of electromagnetic radiation (typically a laser beam which is scanned across the surface) and at least two sensors (adjusted such that the radiation is reflected from a defect-free surface principally received by one of the sensors but that there is a measured amount of radiation in the other sensor).  An average signal of the principal sensor is developed as a function of scan position.  Threshold cir-cuitry detects when the ratio of sensor signal to average signal varies by a predetermined amount.  Special circuitry is used to detect the essentially simultaneous occurrence of at least two different preselected combinations of signal variations to identify the type of defect.

Abstract: Abstract of the Disclosure Defluidization due to excessive agglomeration of fresh carbonaceous feed particles in a fluid-bed reaction zone is prevented by utilizing an overall mechanical energy input to the reaction zone above the minimum energy level needed for dispersion of the particular feed and to break up agglomerates that may tend to form upon injection of said fresh particles to said zone. The overall energy input comprises that supplied by the fluidizing-reagent gas employed; by the carrier gas for the fresh carbonaceous feed, either at conventional, low velocities or employed at high velocity and in sufficient quantity to furnish at least half of said overall mechanical energy input to the reaction zone; and by attrition jets positioned to break up agglomerates.  At high injection velocities, the fresh particles may be preheated to a temperature within the plastic temperature range for the particles, thereby minimizing nozzle erosion at such high injection velocities without causing undue agglomeration of the particles.   A wide variety of desirable processing alternatives may thus be employed while remaining within the permissible limits for the practical operation of fluid-bed reaction zones without defluidization due to excessive agglomeration of fresh coal or other carbonaceous feed materials.

Abstract: LONG STROKE JAR BUMPER SUB WITH SAFETY SLEEVE ABSTRACT OF THE DISCLOSURE      Patterned generally on the Downen Jar disclosed in U. S. Patent No. 2,989,132, the invention retains the ruggedness of its antecedent in enduring down spudding while expanding the range of jarring pressures endured from 40,000 pounds to 90,000 pounds.  This radical improvement followed replacing the keyed spline with a hex spline section and excluding this from the hydraulic jarring control oil chamber and also locating the impact jar faces externally from said chamber, for lubrication entirely by ambient fluid, and transmitting the jarring up blow of the tool directly from the lower end of the external sleeve of the jar to the upper end of the male hexagonal spline sub. Opposed internal female splined sub and external short collar screwed into and onto said sleeve and sub, respectively, and readily replaceable, provide the juxtaposed jar impact faces, thus greatly strengthening the jar and simplifying its servicing.      A separate metering sub heavily reinforces the midsection of the outer protective draft sleeve of the tool and protects the metering sleeve and its hydraulic chamber from damage, besides lessening machining costs.  A safety sleeve supported by the metering sub through matching ground end faces retards "down bumper" movements when resetting the tool for a jarring operation to prevent these damaging the tool, due to spudding the tool.
