Abstract: TITLE APPARATUS FOR SHARPENING BLADES MOUNTED           ON DRUMS                     INVENTOR Fred Oswald ABSTRACT OF THE DISCLOSURE      Apparatus for sharpening the operative cutting surface of a blade while the blade is mounted on a drum comprising a mounting unit for attachment to the drum and a linkage pivotable supported on the mounting unit and carrying a rotatable sharpen-ing member in the form of a cup wheel.  The linkage is composed of a plurality of link members connected for pivotal movement about axes which are parallel to the pivot axis of the linkage to the mouning unit and parallel to the surface of the blade to be sharpened.  The cup wheel is driven in rotation via a flexible shaft and the arrangement of the linkage is such that the sharpening surface of the cup wheel is constrained to lie in planes parallel to the pivot axes while the cup wheel is dis-placeable along the cutting surface of the blade and constrained to move in a plane perpendicular thereto.  An adusting device can be employed to modify the angular position to the linkage relative to the mounting unit and thereby of the angle of the sharpening surface of the cup wheel so that the grind angle can be adjusted while the mounting unit is secured to the drum.

Abstract: MILL FOR ROLLING CONTINUOUSLY CAST INGOT                Abstract of the Disclosure A rolling mill, comprising a movable mill stand mounted in slideways and enclosing grooved mill rolls whose necks are coupled with a hydraulic drive and with gear wheels in mesh with each other. A drive for reciprocating said movable mill stand is equipped with at least two linear inductors installed immovably and at least two electrically conductive bars con-nected rigidly to movable mill stand separators and braces. The bars are adapted to move intermediate of said inductors and have a length exceeding that of said inductors for a value of at least maximum transfer of said movable mill stand. By establishing inductive currents and, hence, electromagnetic forces in the bars, the inductors develop through said bars pulling or pushing forces acting on said movable mill stand and, essentially, sufficient to provide a requisite roll force, The mill roll hydraulic drive is an auxiliary one.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention provides a novel process for the preferential chlorination of alumina over silica in the carbo-chlorination of kaolinitic ores to produce aluminum chloride.  The process comprises introducing small amounts of alkali metal compounds with oxyanions into the carbo-chlorination process.  Preferred embodi-ments are directed to particular compounds of alkali metals with oxyanions selected from the group consisting of carbonates, sulfate, hydroxides, oxides, phosphates, or the like.  The present invention results in signifi-cantly reduced energy, manufacturing, and equipment costs and thus represents a breakthrough in the utilization of domestic ores such as kaolinitic clay for the production of aluminum chloride or of alumina through oxidation of the aluminum chloride.

Abstract: SELECTIVE ERASURE OF IMAGE RECORDING DEVICES    ABSTRACT OF THE DISCLOSURE         Method and apparatus for selectively erasing informa-tion formed on the surface of image recording device which deforms when illuminated in the presence of an electrostatic field applied thereacross.  The image recording device, com-prising a layered structure consisting of a conductive trans-parent substrate, a photoconductive layer, a deformable elastomer layer and a deformable electrode, is initially raster scanned by information containing light through the photoconductor layer with voltage applied between the conductive electrodes whereby the elastomer and deformable electrode are deformed in accord-ance with the input information.  For selective erasure, the voltage is removed and the device is short-circuited.  With the device shorted, the area to be erased is scanned with the spot of light.  The short is then removed and the voltage re-applied, the remainder of the information except for the area erased, being restored.  Additional information can be written in the erased area if desired.

Abstract: U.S. 636,207 ABSTRACT OF DISCLOSURE A reduced catalyst circulation rate may be obtained in a fluid catalytic cracking process, the spent catalyst circulation rate in said process being controlled by the injection of variable amounts of a control gas into the control riser so as to cause density variations therein, by employing a low pressure drop valve means in the spent catalyst circuit of said process such that the pressure drop across said valve means reduces the pressure drop across the riser and consequently the density within said riser.  The reduction in density within the riser results in a lowering of the catalyst circulation rate.

Abstract: COMPOSITE VIDEO WAVEFORM GENERATOR     Abstract of the Disclosure The generation of a composite video waveform three signals representing video data, blanking, and synchronization information is accom-plished by supplying the video data, blanking and synchronization signals to the cathode side of three different diode circuits. The three different diode circuits are tied to a common voltage source on the anode side of the diode circuits. The forward voltage drop across the diode circuits determines the signal level seen by a video monitor in response to the video data, blanking, and synchronization signals. In a preferred embodiment, at least one Schottky diode is utilized in each diode circuit to provide sharp edge definition for the  composite video waveform. In a less preferred embodiment, conventional silicon switching diodes are used to replace the Schottky diodes but a sacrifice in edge definition for the composite video waveform results.
