Abstract: The present invention discloses an animal feed trough which is comprised of two inside legs, two outside legs, two sides, two ends, and a bottom, wherein the sides include end portions, wherein each of the inside legs includes a slot which extends the entire distance of the inside leg and is adapted to accommodate the end portion of one of the sides, wherein each of the outside legs includes a slot which extends the entire distance of the outside leg and is adapted to accommodate the end portion of one of the sides, wherein each inside leg includes a slot which extends the entire distance of the inside leg and is adapted to accommodate the end portion of one of the ends, wherein each outside leg includes a slot which extends the entire distance of the outside leg and is adapted to accommodate the end portion of one of the ends, and wherein each leg includes a positioning means for positioning the leg relative to one of the other legs.

Abstract: A slitting and scoring machine includes an upper tooling roller and a lower tooling roller that cooperate to define a tooling nip. Each tooling roller includes an alternating series of coaxially arranged annular knives, annular dies, and annular mandrels. A web of insulation is drawn through the tooling nip to simultaneously (i) cut the web into strips, (ii) score the strips in a manner that promotes the forming of the strips, and (iii) partially form the strips into modified U-shapes. Each strip includes a longitudinally extending middle segment and a pair of longitudinally extending side segments that extend away from the middle segment in a divergent manner to define a longitudinally extending channel. Longitudinally extending grooves are formed by the scoring at the junctures of the middle segment and the side segments. The scoring/grooves promote the divergent shape of the strip.

Abstract: A support and display assembly for a plurality of thin, relatively lightweight objects such as floppy disks or diskettes, wherein a support frame has a plurality of holder structures rotatably mounted therein and annularly pivotal between two oppositely disposed angularly oriented positions wherein each of the holders and any object contained therein is disposed in a spaced apart, parallel relation to one another when in either of the two opposite positions and further wherein a braking structure is provided to restrict the pivotal movement of the holder structure such that such holder structures will not "automatically" successively travel between the aforementioned opposite positions by a forced displacement of one of such holders.
