Abstract: METHOD OF POLYMERIZING VINYL HALIDE WITH OLEFIN POLYMERS AND COPOLYMERS     AND COMPOSITIONS THEREOF                      Abstract of the Disclosure An improved vinyl halide or vinyl halide copolymer containing up to 50 percent of a comonomer can be obtained by polymerizing in contact with an aliphatic hydrocarbon olefin homopolymer, copolymer or ter-polymer in a process of bulk polymerization comprising single stage or two-stage bulk polymerization wherein high speed agitation is used during the first stage and low speed agitation is used in the second stage.  By polymerizing in the presence of the olefin polymer or co-polymer, reduced particle size, reduced lump formation, and lower melt viscosity and improved impact strength can be obtained in the resin product.  Small amounts of the olefin polymer or copolymer are effective in providing particle size control, reducing lump formation and eliminating scale build-up.  Larger amounts of olefin polymer increase impact strength, reduce melt viscosity and provide excellent mold release properties in the final product.

Abstract: ABSTRACT OF THE DISCLOSURE         Curtain coater method and apparatus is disclosed for coating objects wherein the coater head is maintained substantially full of coating material, the material is discharged through an elongated adjustable orifice at a rate to form a stable or unbroken curtain, and an object is conveyed through the curtain at a velocity to deposit a layer of the material of pre-determined thickness onto the object.  The head is provided with a longitudinally split, resilient, metallic, tubular member, with orifice knives carried thereby along the split, one knife being movable by hydraulic actuators with respect to the other knife to define the elongated adjustable orifice.  A crank and rack arrangement, carried by the head, is used to adjust the stroke of the hydraulic actuators, and thereby to regulate the orifice width.  The tubular member is provided with an elongated filler tube that has a trough in its upper quadrant to distribute the material evenly throughout the entire length of the tubular member, thus reducing turbulence near the entry.  The filler tube and the tubular member form passages therebetween, which provide for an increased speed of the material as it approaches the orifice, thereby reducing precipitation of solids.  The ends of the tubular member are sealed by end assemblies that accommodate to the changing shape of the tubular member.  Windscreens surround the head to protect the curtain.  Hydraulic cylinder apparatus is provided which can raise, lower, and level the head longi-tudinally, and laterally.  A narrow receptacle, which minimizes the amount of material used in the coater, and aids in the conveying of small objects, is provided on the conveyor.  An hydraulic drive system is utilized to control the curtain coater.

Abstract: ABSTRACT      ACCELERATING AND DECELERATING MOVING WALKWAY  WITH MINIMAL WALKWAY SURFACE IRREGULARITIES            An accelerating and decelerating moving walkway, includ-ing a plurality of overlapping platforms formed such that walkway surface irregularities are minimized and such that the platforms change direction in a minimal amount of space, is disclosed.  Each platform includes a pallet and a tapered, trailing edge flap.  The underside of the flaps are combed and mesh with the combed upper-side of the platform that they overlap.  Each flap is hinged to its associated pallet in a manner that allows only a limited amount of rotation.  Surface irregulari-ties, which occur primarily when the overlapping plat-forms are stretched out in the constant speed zone, are minimized by convexly contouring the upper surface of the pallets in the direction of platform overlap; and, by controlling the rotation of the flaps so that contact is maintained between the flaps and the platforms they overlie.  In regions where changes in the direction of platform movement occur, adjacent platforms are first separated, so that they no longer mesh and, then, are turned. After being turned, the platforms are realigned and brought back together.  Separation, turning, and realigning the platforms is controlled by a trailing edge guide mechanism.  The trailing edge guide mechanism includes platform support arms, attached to the rear of the outer edge of each pallet, and guide rails located around the outer periphery of the change of direction regions.  The support arms engage the guide rail and, as the platforms are slightly accele-rated, support the rear edge of the related platforms so that they are separated from the platforms they overlap.  After turning and realignment, the platforms are joined and decelerated slightly.

Abstract: A B S T R A C T            An LSI monolithically integrated semiconductor circuit con-sisting of sequential circuits and combinational circuits contains a considerable number of storage elements designed as latches which for error detection are assembled into a shift register.  If a sequential circuit thus built of several minimum replaceable units is error checked according to the invention no major additional process steps in the form of  further terminals and connecting pins to a module representing the minimum replaceable unit will be required. As disclosed by the invention, by minor modification of the respective input circuits in the minimum replaceable units, the first two shift register stages of a respective minimum replaceable unit are first brought into their respective complementary states.  Then the shift register contents are read out in a conventional manner, with the bit positions represented respectively by the first two shift registers in all minimum replaceable units being examined at the shift output for bit equality.  If bit equality is found it can be concluded that the directly preceding minimum replaceable unit shows a stuck fault.  After the defective minimum replaceable unit has been exchanged the stuck fault test is repeated so a  to be able to isolate any other stuck faults that might precede that minimum replaceable unit.
