Abstract: ABSTRACT          A method and apparatus is disclosed for selectively providing to a human operator/driver selected highway information regarding types of services available at selected locations along a roadway.  Selected highway information is stored and made available with respect to distance markers such as mile markers (or kilometer markers), along a roadway.  For example, a mass plug-in data cartridge storage media permanently stores, in digital form, data related to services (and other pertinent information) available along a selected roadway.  This data is indexed according to distance marker indicators along the roadway.  A ROM (read only memory) may be used to store information and a RAM (random access memory), referred to as "scratch pad memory", may be used for temporarily receiving and storing data.  A ROM contains a control program for controlling the apparatus.  A keyboard for input data entry allows the operator/driver to provide the necessary input data to indicate the selection of highway from which he desires roadway information.  Preferably an alpha-numeric character display is included for providing a visual indication of the selected roadway information.  A speech synthesizer may also be included for audibilizing the selected information.  The complete system is preferably controlled by a micro-processor which itself is controlled by a program contained in ROM.  The micro-processor may be any suitable standard micro-processor commercially available.

Abstract: Abstract of the Invention An apparatus for correcting errors in color signal transitions includes a color limit signal producer.  A wide bandwidth luminance signal is applied to the color limit signals producer which develops a limiting signal representing a constraint for a particular narrow bandwidth color difference or primary color signal.  This limiting signal is combined with its associated color difference or primary color signal in combining means.          The output of the signal combining means is a color difference or primary color signal that has amplitude values within the constraint imposed by the limit signal.

Abstract: ABSTRACT OF THE DISCLOSURE    A method for precipitating vanadium from vanadium bearing liquors comprises adjusting the pH of the vanadium bearing liquor with a precipitating agent selected from the hydroxides of Na, K and Ca to a range of about 5.5 to 6.5, preferably 6.0 to 6.2 so as to precipitate vanadium in the trivalent and tetravalent states.  Remaining traces of vanadium are then cemented by additions of calcium hydroxide, calcium oxide or mixtures thereof.  The dried precipitate is then heated in the presence of air and Na and/or K so as to form a reaction product in the form of a water soluble salt which, when dissolved in water, results in vanadium in its pentavalent state.

Abstract: ABSTRACT   A video stream processing system comprising a novel modular family of image processing and pattern recognition submodules is provided, with the submodules utilizing a unique system signalling and interface protocol, and thus can be cascaded and paralleled to produce complex special purpose image processing systems which can operate at video or near video data rates.  A stream of digitized pixel data is pipelined through a variety of submodules to support a wide variety of image processing applications.  A common video interface provides for handling pixel data in the video signal path and a processor interface allows communication to any modern microprocessor for overall system control, for optional additional image processing and for defining options within each submodule.   In addition, a video stream processing system frame buffer controller is provided for controlling external dynamic random access memory (DRAM) of a frame buffer and interfacing to the video stream processing signal bus.  The frame buffer controller has four interfaces; video input interface, video output interface, memory interface and processor interface.  The circuit can input image data from a camera and store the frames in external DRAM,  The circuit provides for external processor access to pixels in the frame buffer and for output of the frame or portions of the frame, as well as output of frames in a format of CRT display and external DRAM refresh.     In addition, a video stream processing dither circuit for dithering gray level images for output to a bi-level display such as a dot matrix printer or bit-mapped CRT.  The circuit includes an intensity correction look-up table and a resampling scaler capable of scaling independently in each dimension.  The dither logic utilizes a varying threshold with an alternating checkerboard pattern with the addition of random noise and allocation or error terms to adjacent image pixels.

Abstract: ABSTRACT OF THE DISCLOSURE    Filter Cleaning A porous electrically conducting filter, e.g. a membrane for filtration equipment, is cleaned by setting up an electrochemical cell comprising the membrane as a first electrode (usually the cathode), a second electrode, and an electrolyte capable of being electrolysed to a gaseous product at the first electrode.  When a potential is applied across the cell, the gaseous product of electrolysis (e.g. in the form of microbubbles) cleans the surfaces of the membrane by forcing foulant material therefrom.      The electrolyte is constituted by the liquid being filtered (with the possible addition of a salt to increase electrical conductivity, if necessary) thus enabling filter cleaning to be carried out in situ whilst the liquid being filtered continues to be passed through the filter.

Abstract: ABSTRACT OF THE DISCLOSURE An internal combustion engine of an automotive vehicle has a cylinder block formed with a cylinder bore, and a piston is fitted in the bore and reciprocates in it. A cylinder head is affixed to the cylinder block and defines a combustion chamber in cooperation with the piston and the cylinder bore.  This cylinder head is formed with a portion which in cooperation with a portion of the piston defines a squish area of the combustion chamber, and with a coolant passage which substantially follows through the cylinder head adjacent to the squish area so as directly to cool the squish area.  The coolant passage is of substantially the same cross sectional area along its extent. Thereby, the flow of coolant through the coolant passage is kept substantially uniform and at uniform speed throughout its extent, and cooling of the squish area is enhanced.  If the squish area bulges inwards towards the central axis of the cylinder bore, then the inner wall of the coolant passage may bulge inwards so as to follow the inward bulging of the squish area; and in this case the outer wall of the coolant passage may likewise bulge inwards so as to follow this inward bulging of the inner wall of the coolant passage.  The inlet or the outlet of the coolant passage may be restricted by a bulge defined by a portion of the cylinder head which surrounds a cylinder head bolt receiving hole formed in the cylinder head.

Abstract: Abstract of the Disclosure A concentrated aqueous black liquor containing carbonaceous material and  alkali  metal  sulfur  compounds  is  treated  in a  gasifier  vessel containing a relatively shallow molten salt pool at its bottom to form a combustible gas and a sulfide-rich melt. The gasifier vessel, which is preferably pressurized, has a black liquor drying zone at its upper part, a black liquor solids gasification zone located below the drying zone, and a molten salt sulfur reduction zone which comprises the molten salt pool. A first portion of an oxygen-containing gas is introduced into the gas space in the gasification zone immediately above the molten salt pool. The remainder of the oxygen-containing gas is introduced into the molten salt pool  in an amount sufficient to cause gasification of carbonaceous material entering the pool from the gasification zone but not sufficient to create oxidizing conditions  in the pool.   The  total  amount of the oxygen-containing gas introduced both above the pool  and into the pool constitutes  between  25  and  55%  of  the  amount  required  for  complete combustion of the black liquor feed.  A combustible gas is withdrawn from an  upper portion of the drying zone,  and a melt in which  the  sulfur content is predominantly in the form of alkali metal sulfide is withdrawn from the molten salt sulfur reduction zone.
