Abstract: ABSTRACT OF THE DISCLOSURE    An improved camera and process of coding images and a product produced thereby is described in which an image of graphics is scrambled by operation of a pseudoscopic camera.  The graphics and focal plane-type shutter are moved simultaneously relative to  . an objective lens and a graticule so as to produce an image of the graphics which will appear inchoate to ordinary vision.  The image can be unscrambled by viewing the same through a graticule of the same nature as that used in the scrambling process.

Abstract: ABSTRACT OF THE DISCLOSURE: A locking crankcase drain valve assembly for replacing the standard oil drain plug commonly used for draining used oil from the crankcases of most internal combustion engines.  The assembly includes a valve housing for mounting in the drain opening of the crankcase formed with a central passage therethrough and a transversely extending valve opening intersecting the central passage.  A valve member is pivotally attached to the valve body and is formed to move in and out of sealing engagement with the central passage.  A lever attached to the valve member permits opening and closing of the valve member without any special tools. The valve member is held in the closed position by rotating a lever until a boss on the lever arm is received in a detent in the valve housing.

Abstract: ABSTRACT           An admixture of waste (oil-well) drill cuttings, drilling fluid and by-products of rotary drilling are separated into good-quality water and high-density solids by chemical and mechanical means in original earthen-mud storage and/or reserve pits.  The treatment produces two useful benefits:  (1) good-quality water (useful for agri-culture or for drilling a new well) is recovered, and (2) resulting concentrated solids are of such a high density that the land area occupied by and containing such dewatered solids can be immediately leveled and restored to the same use it had before the well was drilled.  The effect is a reduction in energy of at least 75 to 85 percent over the present method of hauling whole mud off by trucks to a commercial waste-disposal sito.          When environmental considerations do not require restoration of the site and reserve pits are allowed to weather to a point of collapse, this process reduces or eliminates surface pollution of nearby creaks, rivers and ponds by preventing release of drilling-fluid chemicals.  It *     also effects a net reduction in energy by breaking the pollution chain. Moreover, less equipment and chemicals are required at any point in the cycle.

Abstract: ABSTRACT OF THE DISCLOSURE   Methods and apparatus for continuously mixing fluid processing media with pulp suspensions are disclosed.  The method includes supplying pulp suspensions to the central portion of the substantially planar radial face of a cylindrical rotor, feeding a fluid processing medium to the pulp suspension as it approaches the rotor face, forming an annular gap at the axial outer surface of the rotor, so that the rapid rotation of the rotor causes the pulp suspension and fluid processing medium to flow radially outward along the planar face and to pass axially through the annular gap, and effecting turbulence of the pulp suspension and the fluid processing medium at the entrance to that gap.  The apparatus dis-closed includes a cylindrical rotor having a substantially planar radial face and an axial outer surface, a housing surrounding the rotor including a pulp suspension inlet facing the center of the radial face of the rotor, and an outlet proximate to its axial outer surface, an annular gap between the axial outer surface and the housing along a predetermined portion of the axial outer surface of the rotor, a processing medium inlet for feeding the fluid processing medium to the pulp sus-pension inlet, and turbulence creating fingers located at the periphery of the substantially planar radial face of the rotor to create turbulence in the pulp sus-pension at the entrance to the annular gap.

Abstract: REDUNDANCY SCHEME FOR AN MOS MEMORY                ABSTRACT OF THE DISCLOSURE         A redundancy scheme is described for use with an MOS memory having a main array of memory cells, and a plurality of spare memory cells.  Typically, each memory cell is tested for operability by a conventional probe test.  When a defective memory cell is found, an on-chip address controller responds to the probe test finding a defective cell-by permanently storing and rendering continuously available a fully asynchronous electrical indication of the address of the defective cell.  The address controller compares its stored data with memory cell information received during normal memory operation, and generates a control signal indicative of the receipt of an address which corresponds to a defective cell.  A spare cell selector responds to the control signal by electrically accessing a spare memory cell and by pro-hibiting access of the defective memory cell.

Abstract: A B S T R A C T            PROCESS AND REACTOR FOR THE PREPARATION OF SYNTHESIS GAS     Gasifier wherein coal dust is introduced from at least one passage in its sidewall and oxygen-containing blast is introduced essentially perpendicular to the coal flow, preferably from below, so as to form a horizontal flat disc. The contact between the hot slag falling down in the bottom of the reactor and the oxygen causes a carbon-free slag and some preheating of the blast.     Since burners are not used in the present gasifier difficulties of flashback and flame impingement are obviated. Moreover, the coal gasification is more efficient, because carbon remained in the slag is completely combusted while falling down through the rising oxygen stream.
