Abstract: DOT MATRIX PRINTER WITH SLANTED PRINT HEAD AND MODULAR SKEWING OF DOT PATTERN               INFORMATION Abstract of the Disclosure A high resolution letter quality 24 by 40 dot matrix ink jet printer includes a movable print head having print elements disposed to print along a slanted line, a character generating module providing character dot patterns to be printed and a modular skewing circuit arranged to receive the dot pattern information and provide the information to the print head in a rearranged order that corresponds to the order in which dot patterns are printed by the print elements.  Because the skewing circuit divides each character dot pattern into eight dot pattern modules and operates on the dot pattern modules one at a time in sequence, the finer resolution of a slant head printer can be obtained without need for a huge triangular shift register operat-ing on all of the dot rows of a dot column in parallel to skew the dot pattern information into conformity with the correspond-ing relative print element locations.

Abstract: ABSTRACT OF THE DISCLOSURE         A box composed of individual pressed material parts and suited for shipping of fruits, vegetables, and the like and adapted for storage in piles.  The box comprises two pairs of substantially square or rectangular substantially flat side panels of substantially equal shape.  The longitudinal upper edges of the panels are turned outwardly and the longitudinal lower edges are turned inwardly so as to engage each other upon storage of the boxes in piles.  Abutting corner sections of each panel are turned outwardly at an obtuse angle along most of their vertical length, the upper ends of the corner portions thus forming an enlarged base when the boxes are piled up upon each other, and a continuous straight channel extending parallel to and above the lower edges of the box and receiving a bottom member.

Abstract: ABSTRACT OF THE DISCLOSURE     Improved method and apparatus for indicating blood pressure and the like in a varied-pressure cuff system wherein blood vessel pulsation signals are supplied to signal processing means for determining the blood pressure.  The blood pressure pulsations are monitored to detect artifacts and the signal processing means inhibited if an artifact is detected.  Upon detection of an artifact the pressure applied by the cuff is automatically adjusted to repeat the pressure at which the artifact is detected, thereby to seek artifact-free values.  The pressure-repetition may be a discrete pressure or a limited pressure range.  Further, a maximum number of limited-pressure repetitions may be established, after which the entire pressure range must be repeated.

Abstract: ABSTRACT            The specification describes a method of depositing and solidifying thixotropic mud such as red mud, which comprises filtering, washing and mechanically liquefying the mud and then transferring it to a dump for solidification.  The mechanical liquefaction is performed on moist mud having a solids content of over 30% by weight and in the presence of an electrolyte.  The dump is provided with at least one retaining embankment for discharging meteoric water by hydraulic action.          The embankment contains at least one substance having cation exchanging properties whereby alkali metal ions absorbed by the water from the mud are removed from the water before it is dis-charged.  With the same ground area and the same storage height, approximately 1.4 times as much red mud in the moist state can be stored by the above method as in conventional dumping.          Also the dump height can be increased to 3 to 4 times that of a conventional dump.  Therefore, a storage capacity of 4 to 6 times the conventional methods is available by the above method.

Abstract: AMINE TERMINATED POLYMERS AND THE FORMATION             OF BLOCK COPOLYMERS                     ABSTRACT OF THE  DISCLOSURE            Polymers of anionically polymerized monomers such as mono-olefins, conjugated dienes, vinyl substituted aromatics, vinyl substituted pyridine, vinyl substituted quinolines, various aldehydes, various epoxides, various oxetanes, various oxygen-containing compounds, and the like are produced and end capped with a polyisocyanate or polyisothiocyanate having the formula R(N=C=X)n wherein R is a hydrocarbon, n is 2 or 3, and X is oxygen or sulfur.  Such end capped polymers, of course, contain one reacted or connected isocyanate or isothiocyanate group and at least one free isocyanate or isothiocyanate end group, which free end group(s) reacts with an amide to give an imide end group.  The imide termin-ated polymer is then hydrolyzed to form a stable amine terminated polymer.  The reaction of the amide compound with the isocyanate(s) or isothiocyanate(s), followed by hydrolysis, results in the replacement of the free isocyanate or isothiocyanate end group(s) with an amine group(s).  Thus, the amine terminated polymer contains the polymer connected to an isocyanate or isothiocyanate group (now an amide group or a thioamide group), which in turn is attached to the hydrocarbon portion, that is, the "R" portion of the polyisocyanate, which in turn is connected to the formed amine group.  The amine terminated polymers may be stored extended periods of time and then reacted with various polymers, prepoly-mers, monomers,   or various combinations thereof to form various block or graft copolymers.  That is, the amine terminated polymer may be subsequently reacted with any amine reactive compound such as diepoxy monomers or an epoxy prepolymer in the presence of known epoxy catalysts to give a blocked epoxy copolymer.  Similarly, the amine terminated polymer may be reacted with urea prepolymers or urea-forming monomers to yield a block urea copolymer.  Reaction of the amine terminated polymer with urethane polymers, urethane prepolymers, or urethane-forming monomers will yield a urethane block copolymer.  Reaction of the amine terminated polymer with urethane-urea prepolymers or urethane-urea forming monomers will yield a urethane-urea block copolymer.  Similarly, various dian-hydride  and diamine monomers may be utilized to form an imide block copolymer.
