Abstract: Abstract of the Disclosure A rechargeable battery-operated flashlight system includes a housing for the flashlight, batteries and associ-ated circuitry.   A two-pronged plug is rotatably mounted in the housing for movement between two positions, the prongs projecting outwardly through an opening in the housing so that in one position they project into a recess formed by a reentrant portion of the housing and in the other position they project away from the recess.   Resilient contacts connect the prongs to the rest of the circuitry, and engage in detents on the prongs in their two positions to inhibit rotation thereof.  A wall bracket defines a pocket for releasably accommodating a receptacle fixture for receiving the plug prongs in their one position and for supporting the housing during recharging.          In their other position, the prongs can be plugged directly into an AC wall outlet.

Abstract: ABSTRACT OF DISCLOSURE    A  pneumatic  conveying  and  material  blending  system  and method which includes a bin having an open-ended vertical column mounted therein with the bottom of the column being spaced from the bottom of the bin.  The material inlet is located in the bottom of the bin and  a pneumatic conveying system  supplies material to be blended from a source to the material inlet and conveys the material upwardly through the column so that material is discharged from the top of the column in the manner of a geyser whereby it is spread over the top surface of material already in the bin.  The material already in the bin is drawn into the bottom of the column so that material already in the bin is blended with material being conveyed to the bin.  A deflector is positioned over the top of the column to aid in spreading the incoming material.  Booster gas can be supplied through a section of the bin adjacent the bottom of the column.  This gas may be supplied by using a vacuum applied to the bin through a vent in the bin or by a blower supplying air or gas  directly to  a manifold surrounding the gas permeable surface.  The outlet of the bin is coextensive with the inlet of the bin so that material is drawn out of the central opening in the bottom of the bin.          Internal recirculation is also contemplated by this invention.

Abstract: ABSTRACT OF THE DISCLOSURE          Graphics images are generally considered to be those images comprised of text and/or drawings.  Data compression of graphics images is desired whenever a fast image transmission speed is desired in a limited band width channel.  It is also used for storage of a large number of images in a limited capacity storage system.  A high compression ratio is achieved by thresholding the graphics image to a bilevel black-white image at one bit per pixel and then employing a second data compression on the black-white image.  At low resolution, bilevel images hate poor quality at edges and a quality improvement is needed. The data compression apparatus and method disclosed separates the graphics image into at least first and second bit planes, identifies edge pixels from the first bit plane indicating a black/white change, locates the edge pixels and generates at least a single bit for each edge pixel indicating whether the edge pixel has a maximum intensity value such as black or white or an intermediate gray intensity value. Intermediate values are not allowed except at edge pixels which enhances both quality and compressibility of the resulting graphics image.

Abstract: A SYNCHRONIZATION DEVICE FOR DIGITAL FRAME TRANSMISSION      ABSTRACT OF THE DISCLOSURE             A synchronization device for digital data frame transmission system comprising an n bit series register transferring its contents at the line frequency to a parallel register also of n bits. The m first bits of the series register are also directed to a logic circuit detecting their conformity with the beginning of the synchronization word.  When there is conformity, the logic circuit controls a divider dividing by n which controls, in its turn, at the line frequency divided by n, the transfer 15 of the contents of the parallel register to a PROM memory. The purpose of the PROM is to recognize the whole of the synchroniz-ation word. When there is no recognition, the operation of the divide by n divider is inhibited and the procedure begins again.

Abstract: Abstract of the Disclosure A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 343°C+ (650°F+) material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalents of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 482 to about 760°C (900 to about 1400°F), and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 40% to 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight. The spent, coke-laden catalyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated, the sorbed hydrocarbons are stripped from the spent catalyst particles by mixing them with hot regenerated catalyst particles and passing the mixture through an elongated stripping chamber where desorbed hydrocarbons are cracked by regenerated catalyst particles which are present. The stripped catalyst is regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen. The catalyst particles are retained in the regeneration zone or zones in contact with the combustion-supporting gas for an average total residence time in said zone or zones of about 5 to about 30 minutes to reduce the level of carbon on the catalyst to about 0. 25% by weight or less.          The regenerated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil.

Abstract: ABSTRACT OF THE DISCLOSURE An improved balance weight construction and a method of securing such a balance weight to a drive shaft or other tubular body are disclosed.  A generally balance weight is formed with a curved side surface which conforms to the outer surface of the drive shaft.  The balance weight and drive shaft are typically formed of dissimilar materials, such as steel and aluminum, respectively.  The balance weight has a coaxial aperture formed therethrough and a plurality of radially-extending grooves formed in the curved surface thereof which connect the aperture with the edge of the surface.  While the balance weight is maintained against the drive shaft at a predetermined location satisfactory for balancing the drive shaft, a bonding material, such as molten aluminum wire, is supplied within the aperture so as to form a spot or rivet-type weld.  The radially-extending grooves provide passages which allow gases within the aperture to escape, thereby promoting the smooth flow of molten aluminum into the aperture and increasing the reliability of the weld.

Abstract: ABSTRACT OF THE DISCLOSURE This is an electrode for consumable arc melting of zirconium and titanium alloys containing a low melting point alloy constituent.  The electrode uses a low resis-tance  spar  extending  substantially  the  length  of  the electrode and being substantially free of any unalloyed low melting point alloy constituent.  The external member containing  unalloyed  low  melting  point  constituent  is attached to  the  spar member  in a manner to provide a relatively high resistance through the external member in an axial direction of the electrode.  During operation, this minimizes resistance heating of the external member away from the arc and thus premature melting of unalloyed low melting point constituent is generally avoided.
