Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to a ball, which is round and constructed like a shell,  The shell consists of a regular, continuous pattern comprising the very body of the ball.  The pattern has its character from a great number of substantially symmetrical holes in the shell, the total surface of the holes being at least 20% of the total limiting surface of the ball.          This bail will travel more softly in the air and is very little disturbed by wind conditions at outdoor play.

Abstract: IODOPHORS            ABSTRACT  OF  THE  DISCLOSURE     Improved iodophors, namely iodine-containing compositions having use in combatting bacteria, fungi, viruses and other undesirable micro-organisms, are made in the form of solutions of iodine in tertiary amine oxides.   The compositions preferably a liquid medium, which may be water or any monohydric, dihydric or poly-hydric alcohol or mixture thereof, and the iodophor compositions also are preferably made up as acid solutions.   Any of a wide variety of surfactants or combinations of surfactants, whether nonionic, cationic or anionic, can form very advantageous components of iodophor compositions.   The iodophors can also usefully include soluble iodides, which enhance the available iodine concentrations remarkably.   All forms of the compositions are notably stable and effective.

Abstract: ABSTRACT OF THE DISCLOSURE   compositions comprised of a polymer blend of a halogen-containing polymer and a diene/nitrile rubber having active halogen cure sites are covulcanized using a common cure system.  The halogen-containing polymers used in the polymer blend include the commercial polymers such as epihalohydrin polymers, polychloroprenes, fluoroelastomers, halogen-containing acrylates, and halogenated polyolefins.          The curative ingredients employed are those normally used for the cure of the halogen-containing polymer employed in the polymer blend.  These blends exhibit better physical properties such as tensile strength, abrasion resistance and oil swell than prior art blends.  These blends are useful in the manufacture of fabricated products such as gaskets, hoses and printing rolls.

Abstract: Abstract of the Disclosure An extremely short channel Field Effect Transistor (FET) is made by making a first ion implant through a polysilicon mask aperture, converting the surface of the polysilicon into SiO2 to constrict the aperture size and then making a second ion implant of the opposite type impurity through the constricted aperture.  The SiO2 growth effectively moves the edge of the mask by a small controlled distance.  This permits a small controlled spacing between the two ion implants, which is used for defining an extremely short FET channel.  Alternatively a bipolar transistor with a narrow base zone can be made by analogous processing.                             - i -

Abstract: Abstract of the Disclosure Copper is recovered from solutions containing cupric ammoniacal complexes by reducing copper in the complexes to the cuprous state and thereafter precipitating the cop-per as cuprous acetylide by passing acetylene through the solution.  After the cuprous acetylide is separated from the solution and washed thoroughly, it is reacted with ace-tonitrile and an acid to form acetylene and a cuprous-acetonitrile complex:  Cu(CH3CN)?.  The solution containing this complex is then flash distilled to remove the aceton-itrile and to disproportionate unstable cuprous ions into copper metal and cupric ions.  Following the disproportion-ation, the components are separated and copper metal is col-lected.

In the illustrated embodiment when plural motors are driven together they are driven at the same rate although several of the features of the invention are suitable for use in cir-cuits providing contouring control; i.e., where separate motors are driven at separate stepping rates proportional to the relative dis-tances each is to traverse for a single movement.  An acceleration/ deceleration circuit is utilized which provides simple yet highly accurate and efficient control of the stepping motors.  Feed rate compensation for simultaneous drive of two motors is provided.          Also a means is provided to allow stepping rates in excess of the counting rate capability of the microprocessor.

Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a technique for accelerating the Hantzsch reaction, for the clinical determination of triglyceride, so as to permit the reaction to be analytically complete within 15 minutes at 37° C.  As is known, in this Hantzsch reaction, one mole of aldehyde is reacted in a solution predominantly containing    alcohol and water with two moles of a beta-dicarbonyl compound in the presence of ammonia to yield, as a colored derivative, a lutidine.  In the disclosed technique, the solution also contains an organic accelerator compound.  This compound is capable of forming a clear solution with the mixture of components of the reaction solution and is further characterized as having an aprotic internal dipole such that said compound has a distinct center which is electron rich and center which is electron deficient.

Abstract: ABSTRACT OF THE DISCLOSURE         Sectional overhead sliding door has each of the slots between the adjacent panel sections shaped such as to prevent passage of water from outside to the inside of the door, e.g. when the exterior is exposed to heavy rain or the like.  The lower one of each pair of adjacent sections has a step-shaped upper edge disposed such that the lower step section is at the exterior, the higher step section being at the interior of the respective panel.  The lower step section terminates at its inside extremity at an upwardly turned chute or lip which further assists in collecting water that may have been left on the lower step section, to prevent passage of such water towards the interior surface of the respective panel when the respective panel is in a horizontal overhead position on opening of the door.  The advance in the art is in an improved resistance of the door against water penetration, e.g. during heavy rains, through the slots between the panels.

Abstract: METHOD FOR SENSING THE PATTERN                 SIDE OF MICROCIRCUIT CHIPS          Abstract of the Disclosure A collimated beam of light is directed onto a face of a microcircuit chip.  If the configuration side of the chip is up and if the chip has a typical pattern predominantly comprised of two orthogonal sets of lines, the light reflected from the chip will be formed in a cross shaped diffraction pattern with most of the light concentrated in the center of the cross.  If, however, the chip is upside down so that a plain face is exposed to the light, the light will be reflected fairly uniformly from the chip.  By measuring the reflected light in a small center zone as well as in a larger zone and the light measurements are compared, it can be determined whether the diffraction pattern is present thereby revealing whether the chip is right side up, i.e. configuration side up.

Abstract: ABSTRACT OF THE DISCLOSURE         A fine-adjusting arrangement for a pressure-indicating device of a sphygmomanometer.  The sphygmomanometer includes a movable indicator needle, an actuating rod movable in response to changes in the air pressure generated in the sphygmomanometer, and a pair of coupling members intermediate the actuating rod and the indicator for moving the latter along a path between a starting position and an end measuring position. One coupling member is an adjustment plate having a pivot pin for pivotally connecting the rod to the adjustment plate; and the other coupling member is a sector gear operatively connected to the indicator and having an abutment pin spaced from the pivot pin at a spacing which determines the position of the indicator along the path.  The fine-adjusting arrangement shifts the adjustment plate relative to the sector gear to thereby vary the spacing, and also sets the indicator with fine minute continuous adjustment to its starting position.  The fine-adjusting arrangement includes a support mounted on the plate and having a threaded passage, an adjustment member having a threaded shaft portion mounted in threaded engagement with the passage for continuously variable displacement along the passage in direction towards and away from the abutment pin on the sector gear, and a biasing spring for urging the adjustment member into engagement with the abutment pin, and for shifting the adjustment plate relative to the sector gear in response to such displacement of the ad-justment member to thereby vary the spacing between the pins and finely adjust the indicator to its starting position.
