Abstract: A food container includes a base and a lid, and the lid may have a recess configured to receive a second container. The base may comprise a formed cavity that provides a bowl into which food or other items may be placed. The recess in the lid may receive a cup containing another item, such as a condiment or topping. The cup with the condiment or topping may be inserted into the recess, and removed from the recess, without removing the lid from the base. The lid and/or the base may be formed from any suitable materials, such as a transparent or non-transparent plastic material, and/or a compostable material.

Abstract: A food container is provided that has a formed cavity having top edge and two or more flaps coupled with one the top edge. Each of the flaps may extend half-way or more between opposite points of the container. The flaps may include a closure mechanism to secure the flaps in a closed position to provide a covering for substantially all of the area defined by the top edge, thereby closing the formed cavity. The formed cavity may include one or more radiused portions, with one or more of the flaps including a raduised extension that extends outwardly relative to a connection point between the flap and the cavity top edge. One or more of the flaps may include a recessed portion having a flap sidewall that is located adjacent to a formed cavity sidewall when the flap is folded to cover a top opening of the food container.

Abstract: A method and apparatus are for use in the manufacture of self-sealing reinforcement tie rods for reinforcing HVAC ducts, of the type including an elongated threaded rod having fastened inwardly of each end thereof an abutment structure comprising an elongated hollow tubular body having a bore therethrough for coaxially receiving the rod, the tubular body having a longitudinally inwardly located tubular crown portion for attachment to the rod, and a longitudinally outwardly located, radial outwardly protruding annular flange portion for abutting and bracing a duct wall. The apparatus includes a work plate having in the upper surface thereof a slot having a lower wall which slopes downwardly and radially inwardly towards the center of the work plate, on which are positioned a single file line of abutment structures, flange down.

Abstract: An apparatus for assembling air turning vane and rail structures of the type having a plurality of turning vanes consisting of longitudinally spaced apart curved airfoil plates disposed between a pair of parallel upper and lower plate-like rails, and used to promote laminar air flow in heating, ventilating and air conditioning ducts, compresses an array of vanes between a pair of rails to interlock upper and lower transverse edges of the vanes with the upper and lower rails. The apparatus includes a work table for holding the lower rail of a vane and rail structure to be assembled, and lower and upper laterally disposed comb-like vane guides disposed above the work table provided with laterally spaced apart, vertically aligned pairs of slots, each adapted to receive a vane in an upstanding position above an intended fastening location in the lower rail.

Abstract: An air turning vane and rail assembly for promoting laminar air flow in angled duct work transition sections includes longitudinally spaced apart air turning vanes transversely disposed between a pair of flat rails. Each turning vane is a hollow double-plate airfoil having a convex front airfoil plate, and a concave rear airfoil plate joined at their edges. Each rail has a plurality of longitudinally spaced apart, upstanding tabs each having an upper trapezoidally-shaped portion and a lower rectangularly-shaped pedestal portion. Each tab has a pair of laterally opposed, outwardly and downwardly angled edge walls, each joined at its lower end to a vertically disposed pedestal edge wall. The width of the pedestal is greater than the maximum lateral spacing between the front and rear airfoil plates.
