Abstract: METHOD AND APPARATUS FOR VISUAL IMAGE PROCESSING              ABSTRACT OF THE DISCLOSURE     Method and apparatus is disclosed for automatically processing visual images electronically so as to permit intelligent machine analysis of the image content.  A special distributed logic system architecture facilitates rapid real time image analysis and the production of reaction control signals in a high speed production line environment, for example.  Dedicated decision logic is employed to determine in but a single micro-instruction cycle whether a detected corner point of the image should be linked to another already linked chain of such corner points so as to define part of a closed edge contour of the image under examination.  This ability to so rapidly classify encoded corner points as either belonging or not belonging to a given set of such corner points which describe a closed edge contour is quite useful in achieving rapid real time image analysis capability.  Special dedicated data address indexing circuitry is also employed for most expeditiously retrieving successive address linked data words from a data memory in successive single micro-instruction cycles as required to take full advantage of the high speed dedicated corner point matching circuitry.  The dedicated data memory indexing circuitry is provided in addition to the usual program instruction indexing circuitry employed in connection with the instruction register of the associated data processing system.

Abstract: Abstract The dust collection units in a rotary railroad car dumper installation are mounted over the hopper pit along each side of the cylindrical, rotatable dumper frame so that dust ladened air can be sucked directly into the dust collection units without the need for duct work and the collected dust can be returned directly to the pit without the need for easily clogged screw conveyors and small chutes.  The dust collection units also form with air shields mounted on the cylindrical dumper frame, a rotary valve which restricts flow such that ambient air is sucked into the hopper pit by the dust collection units at velocities which exceed the capture veioci-ty of the dust clouds created by dumping of the contents of the car.  The air shields include orthogonal pairs of planar members mounted on the rotary frame.  One planar member extends outward from the top of one side of the car to be dumped such that the side of the car forms part of the air shield and the gap under the car forms, just as the car contents are being dumped, a longitudinal slot through which ambient air is sucked to sweep away the resultant billowing dust cloud.

Abstract: MEMORY USING MULTIPLEXED ROW   AND COLUMN ADDRESS LINES            Abstract A memory of rows and columns of memory cells uses a multiplexed input address buffer having output row-column address lines which are coupled to a multiplexer and to column decoders.  The multiplexer is coupled to row address decoders and serves to selectively couple the address lines to the row decoders.  The address lines typically first carry row address information and then column address information.  The use of a common portion of the address lines to couple the address buffer to the column decoders and multiplexer tends to reduce the overall size of the memory and thereby increases yield and reduces cost.

Abstract: Abstract In a hydrostatic steering device, the steering motor (6) is controlled by a steering valve (4).  When limiting position sensors (27, 28) respond, operating elements are activated which suppress the exertion of pressure on the steering motor (6).  These operating elements are formed by a locking apparatus (24) which mechanically stops the steering wheel (19) against further rotation.  Consequently, when one limiting position sensor responds, the steering valve (4) goes to its neutral position (a), whereby further adjustment of the steering motor (6) is prevented.

Abstract: Abstract For   treating starch  or  starch-containing raw materials, the starting material is subjected to a mechanical treatment, noting that the fraction rich in starch is,  after having been wetted, thermally degraded by applying high temperatures, for example by applying saturated steam at 110 to 130°C. The thermally degraded starch fraction is cooled down to saccharification tempera-ture and saccharified by adding enzymes. For obtaining  a   higher reaction speed in the subsequent fermentation stage and for  better   energy utilization, the saccharified dispersion is cooled down to fermentation temperature or a slightly higher tempera-ture by dilution and the undissolved solid matter is separated, optionally after a flocculating stage, prior to the fermentation stage. This additional separation of solid matter immediately prior to the fermentation stage at temperatures exceeding the fermentation temperature or being already said fermentation temperature provides the possibility to immediately obtain a substrate of low con-tent in solid matter, in which substrate the fermentation can more rapidly proceed.
