Abstract: An apparatus for stacking generally-thin pieces at a stacking station is provided herein. Those pieces have projections extending from a side of each piece. The apparatus includes a first conveyor for conveying the pieces along a first path toward the stacking station with the projections of the pieces extending generally-upwardly. The apparatus also includes a second conveyor for conveying the pieces along a second path to the stacking station. The second conveyor inverts the pieces before they reach the stacking station so that the projections of the pieces extend downwardly in the stacking station and intermesh with the projections of the pieces which have already been conveyed to the stacking station by the first conveyor. The first and second paths are non-coincident. The second conveyor is arranged with respect to the first conveyor so that the pieces which are on the second conveyor and which are moving along the second path move downwardly into the stacking station while the pieces on the first conveyor which are moving along the first path enter the stacking station from one side of the stacking station.

Abstract: A hammermill having a rotor assembly and a screen bar assembly is provided to reduce oversized wood chips. The hammermill may also be used to reduce wood and/or bark, the rotor assembly includes flexible hammers which are pivotally attached to allow each flexible hammer to move radially inward or radially outward during rotation of the rotor assembly.  Each flexible hammer preferably includes a recess with a portion of a support rod disposed therein to limit radial movement inward and outward relative to the rotor assembly.  The screen bar assembly includes a plurality of screen bars having a beveled surface formed along one edge of each screen bar disposed adjacent to the rotor assembly.  The flexible hammers allow the rotor assembly to rotate at lower revolutions per minute which reduces the amount of fines and undersized wood chips produced by the associated hammermill. Cooperation between the flexible hammers and the configuration of the screen bar assembly along with the beveled surfaces further reduces the amount of fines and undersized wood chips produced by the associated hammermill.

Abstract: An engine (1) has first and second cylinder groups (1a) and (1b). The first cylinder group (1a) is connected to a three way (TW) catalyst (8a). The second group (1b) and the TW catalyst (8a) are connected, via an interconnecting duct (13) to an NH3 adsorbing and oxidizing (NH3-AO) catalyst (14a). The first group (1a) performs the rich operation, and the second group (1b) performs the lean operation. In the TW catalyst (8a), NO x exhausted from the first group (1a) is converted to NH3, and the NH3 reduces the NO x exhausted from the second group (1b) in the NH3-AO catalyst (14a). A NO x occluding and reducing (NO x-OR) catalyst (11a) is arranged in the exhaust passage between the second group (1b) and the interconnecting duct (13), to thereby suppress the NO x amount flowing into the NH3-AO catalyst (14a).

Abstract: A flush valve includes a body with an inlet, an outlet, a valve seat at the outlet, and a piston movable in the body toward and away from the valve seat to control flow through the outlet. The piston has a chamber and there is a refill orifice in the piston connecting the chamber with the body inlet. Pressure in the chamber maintains the piston closed upon the valve seat. A relief valve in the piston vents the chamber to the outlet to permit the piston to move away from the valve seat to open flow from the inlet to the body outlet. The piston has a guide portion which extends downstream of the valve seat when the piston is in the closed position. The guide portion of the piston has a plurality of outwardly extending axial ribs, the outer surface of which is radially in alignment with the path of flow through said valve seat. The piston area between the ribs is closed by a skirt to confine the path of flow exteriorly of the piston portion to provide a defined flow path through the valve seat from the inlet to the outlet.

Abstract: Recombinants containing and expressing lentivirus, retrovirus or immunodeficiency virus DNA and methods for making and using the same are disclosed and claimed. In an exemplified embodiment, attenuated recombinant viruses containing DNA encoding a feline immunodeficiency virus epitope such as an antigen, as well as methods and compositions employing the viruses, expression products therefrom, and antibodies generated from the viruses or expression products, are disclosed and claimed. The recombinants can be NYVAC or ALVAC recombinants. The DNA can encode at least one of: Env, Gag, Pol, or combinations thereof such as Gag and Pol or protease or Env, Gag and Pol or protease. The recombinants and gene products therefrom and antibodies generated by them have several preventive, therapeutic and diagnostic uses. DNA from the recombinants are useful as probes or, for generating PCR primers or for immunization. The immunogenicity and protective efficacy of immunization protocols involving ALVAC-FIV and priming with a recombinant canarypox virus ALVAC-FIV followed by a booster immunization with inactivated FIV-infected celled vaccine (ICV) was evaluated against FIV challenge in cats and the protocol was shown to effectively induce FIV-specific protective immune responses. Further, it was found that immunized cats were fully protected from an initial challenge with a slightly heterologous FIV strain (50CID50) and were partially protected from a second challenge with a distinctly heterologous FIV strain (75CID50) given eight months after the initial challenge without any intervening booster.

Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer.      The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.
