Abstract: ABSTRACT            This invention enables solid materials such as cellulose fibres to be pulverized and mixed with chemicals in a continuous or batch process by centrifugal action through the application of high pressure, multistage impeller blading intermeshing with concentric slotted annular vanes,  The material to be treated is fed through a single central aperture and propelled outwards through preset labyrinths formed by the impeller blading and the slotted vanes.  The pulverizer also permits alteration of the geometry of these labyrinths thus causing the texture or consistency of the pulverized material to be varied.

Abstract: ABSTRACT OF DISCLOSURE A fluidized bed apparatus having an outer vessel provided at a lower region witha plenum chamber as well as a grid situated directly above the plenum chamber and carrying a plurality of nozzles through which gas flows from the plenum chamber into the space in the vessel above the grid.  These nozzles provide a given pressure drop in the gas flowing therethrough while as the gas flows from the plenum chamber through each nozzle there is also provided by way of a suitable structure a preliminary pressure drop, so that a two-stage pressure drop is provided in the gas flowing through each nozzle from the plenum chamber into the vessel above the grid.  In this way it is possible to achieve a flow of gas above the grid sufficient to maintain the particles suspended in the fluidized bed while attrition of the particles is maintained at a minium so that very little if any fines flow out of the vessel with gas which is formed therein.  According to this method, the particles are petroleum coke particles while the gas is a mixture of steam and air maintained in the plenum chamber at a pressure of only 1-5 psig above the pressure in the bed while at the region of the interior of the vessel above the grid the temperature is on the order of 1500-1800°F. The grid supporting the nozzles is sloped 3° to 5° downwards towards a center well and supporting member to allow solid agglomerations such as lumps of coke and slag to move radially inward into the well for withdrawal.

Abstract: ABSTRACT       Method and means for removing foreign matter and damaged fruit from a continuous supply or machine harvested tomatoes as they are moved through the crop discharge section of the harvester.  The element is spaced from the exit end of the first conveyor by a distance which allows foreign matter such as dirt, stones, stems and small or damaged fruit to pass under the element and fall to the ground.  The tomatoes to be gathered are too large to pass through the gap between the first conveyor and the hinged element, thus passing over the element and being deposited on the final discharge conveyor.

Abstract: ROUTE CONFLICT ANALYSIS SYSTEM FOR CONTROL                OF RAILROADS                 Abstract of the Disclosure A centralized traffic control system for complex railroad areas analyzes the intended path of travel of various trains to determine the existence of any conflicts.          When one or more conflicts are detected, the system ana-lyzes various options to resolve the conflict with a minimum disruption to the system based on predetermined constraints. The analysis proceeds on the basis of a heuristic search for conflict resolution.  A successful resolution of the conflict is then implemented without requiring operator intervention.

Abstract: Abstract of the Disclosure The specification discloses a target of an image pickup tube produced by at first forming a striped transparent conductive film on a substrate in such a manner that the angle formed between the surface of the substrate and the edges of cross-section of the film falls below 20°, and then forming a photoconductive film on the striped transparent conductive film.  In order to control the angle formed between the surface of the substrate and the side edges of cross-section of the transparent conductive film, a mask of a predetermined pattern is first formed on the transparent conductive film with a post-type photosensitive material, and is then subjected to irradiation with ultraviolet rays.  The mask is then heat treated so that the side edges of the mask may be suitably tapered.  Finally, the transparent conductive film is formed by a sputter etching technique.  The target thus produced has improved characteristics compared with targets formed in the conventional manner, especially improved after-image characteristics.

Abstract: "DICTATION-TRANSCRIPTION METHOD AND SYSTEM"        ABSTRACT          A dictation-transcription method and system in which dictated material and instructions concerning the dictated material for use during the transcribing of the dictated material are separately recorded on a recording medium along with indexing signals which include indexing signals identifying the location on the recording medium of the separately recorded instructions concerning dictated material.  The recording system and method permit the recording of instructions at any location on the recording medium relative to the dictated material including a location along the length of a recording medium which is the same as the location of the dictated material to which an instruction relates without obliterating any of the dictated material, while at the same time preventing the inadvertent placing of the recording system in a recording mode of operation following the recording of an instruction which would cause dictated material to be inadvertently obliterated.  In the transcribing of the dictated material, the system and method provide for the selective transfer of the audio circuit through which the dictated material is being transcribed from the dictated material to an instruction with respect to the dictated material when a signal is heard indicating that there are instructions concerning the dictated material on the recording medium.

Abstract: ABSTRACT: "Cathode ray tube".     In a cathode-ray tube, in particular a camera tube, the inner wall of the glass envelope is coated with an electrically conductive material. In order to form separate wall electrodes, said wall coating is interrupted in the proximity of electrodes extending transversely to the wall coating. These electrodes extending transversely to the wall coating are supported by a supporting surface extending transversely to the longitudinal axis of the tube. At the area of each of the interruptions the envelope has a stepwise decrease of the inside diameter in two steps. In the direction of decreasing diameter the first of these steps constitutes the supporting surface for the electrode extending transversely to the wall coating and the inter-ruption in the wall coating is provided on a wall portion of the second of these steps. The interruptions provided in this manner do not exert any disturbing influence on the electron beam in the tube.
