Abstract: An expansion loop for a piping system. The expansion loop has a first flexible conduit with a first end and a second end and a second flexible conduit with a first end and a second end. A first rigid conduit is connected between the first ends of the first and second flexible conduits. Additional rigid conduits are connected to both of the second ends of the flexible conduits. These additional rigid conduits include a stainless-steel elbow, a conversion conduit, and a copper conduit. The expansion loop may be installed wherein the flexible conduits are bent, when fluid flows, the flexible conduits straighten out and are not bent.

Abstract: A portable beehive is disclosed for use in transporting a population of bees between a beekeeper facility and an orchard or the like. The portable beehive includes a box formed from a folded, single-piece blank, and a removable top cover. The interior of the box has inner end walls which form ledges for suspending honeycomb frames within the box. An exit opening is formed through an end wall of the box, and the exit is closed or opened by a door flap. The door flap, when opened, functions as a mat upon which may be placed concentrated pollen for transfer to the bees. Pivotable carrying handles perform multiple functions including holding the top cover in place, limiting the movement of the honeycomb frames within the box, and holding a bee food container in place atop the cover. A space is formed between the rear inner end wall and the rear outer end wall in which bee food may be placed; openings are provided in the rear inner end wall through which bees may access the food.
