Abstract: Porcine circovirus-2 (PCV-2) is a recently identified agent wherein the potential spectrum of PCV-2-associated disease has been expanded by evidence of vertical and sexual transmission and associated reproductive failure in swine populations. PCV-2 was isolated from a litter of aborted piglets from a farm experiencing late term abortions and stillbirths. Severe, diffuse myocarditis was present in one piglet associated with extensive immunohistochemical staining for PCV-2 antigen. Variable amounts of PCV-2 antigen were also present in liver, lung and kidney of multiple fetuses.

Abstract: The invention relates to new porcine circovirus strains isolated from pulmonary or ganglionic samples obtained from farms affected by the post-weaning multisystemic wasting syndrome (PMWS). It relates to purified preparations of these strains, conventional attenuated or inactivated vaccines, recombinant live vaccines, plasmid vaccines and subunit vaccines, as well as reagents and diagnostic methods. It also relates to the DNA fragments which can be used for the production of subunits in an in vitro expression vector or as sequences to be integrated into a virus or plasmid type in vivo expression vector.

Abstract: The cloning of a novel PCVII viral genome is described as is expression of proteins derived from the PCVII genome. These proteins can be used in vaccine compositions for the prevention and treatment of PCVII infections, as well as in diagnostic methods for determining the presence of PCVII infections in a vertebrate subject. Polynucleotides derived from the viral genome can be used as diagnostic primers and probes.

Abstract: A dual wheel assembly is formed by an inner wheel (10) and an outer wheel (30) coaxially mounted on a common hub (11). The inner wheel (10) has an inner tire (13) mounted on an inner wheel rim (12). The outer wheel (30) has an outer tire (13A) mounted on an outer wheel rim (32). The wheels (13, 13A) are of the same size, but the diameter of the outer wheel rim (32) is smaller than the inner wheel rim (12), to permit the inner tire (13) to pass over the outer wheel rim (32), thereby enabling the inner tire (13) to be removed without first removing the outer wheel rim (32). Removable bead seats (37, 40) are provided between the outer wheel rim (32) and its tire (13A). These bead seats are thicker than the corresponding bead seat(s) on the inner wheel (10) to compensate for the reduced diameter of the outer wheel rim.

Abstract: A logic device for performing a plurality of logic functions employs a plurality of logic elements interconnected by a plurality of switching boxes. A set of configuration bits are provided to the logic. The configuration bits represent a logic circuit that has been partitioned into two or more contexts. A subset of the configuration bits representing the portion of the logic circuit to be performed is selected by a number of context input lines. Operand bits are also provided to the logic element. By using virtualization registers, the output of a logic element in one context can be used as an input in another context. The output for a logic function is selected by the operands and stored in a register bank in such a way that it may later be retrieved by the context number it is associated with.

Abstract: An apparatus for removing skin from a convex surface of a section of fruit. The apparatus includes a substantially U-shaped peeling blade and a feeder which in use contacts and grips the fruit or vegetable at a location about opposite the apex of the peeling blade so as to urge the fruit past the peeling blade, characterized in that the apparatus also includes at least one guide for guiding the fruit past the peeling blade.

Abstract: An apparatus for removing skin from a convex surface of a section of fruit. The apparatus includes a curved peeling blade which presents a concave peeling surface to the convex surface of the section of fruit and a drive gear wheel in mesh with an idler gear wheel. Each wheel has a concentric outwardly extending fruit gripping portion which are profiled such that in combination they conform to the curved peeling blade. When the drive wheel is driven and the wheels are rotating, the fruit gripping portions grip a section of fruit and urge the section of fruit past the peeling blade so as to remove the skin from the fruit.

Abstract: An improved fastener is provided for use in retaining vertebrae in a desired spatial relationship. The fastener has a mounting section with a first external thread to engage a vertebra. The fastener has a retaining section with a second external thread to engage an internal thread on a retaining element, such as a nut. A circular intermediate section interconnects the mounting and retaining sections of the fastener. A plurality of spaced apart recesses are formed in the intermediate section. Each of these recesses has a surface for receiving force to rotate the fastener relative to a vertebra. The circular intermediate section may include an annular end surface which faces toward a retaining section and a cylindrical outer side surface. Each of the recesses has an opening which extends from the annular end surface into the cylindrical side surface.

Abstract: An improved fastener is provided for use in retaining vertebrae in a desired spatial relationship. The fastener has a mounting section with a first external thread to engage a vertebra. The fastener has a retaining section with a second external thread to engage an internal thread on a retaining element, such as a nut. A pair of parallel flats are formed on opposite sides of the retaining section. The flats are spaced apart by a distance which is substantially the same as or greater than a root diameter of the external thread on the retaining section. A driving recess in an axially outer end of the retaining section has arcuate corner portions which receive force to effect rotation of the fastener relative to a vertebra engaged by the mounting section. The arcuate corner portions of the driving recess are offset from a plane containing the longitudinal central axis of the retaining section and extending perpendicular to the flats.
