Abstract: The disclosed conveyor has a frame which comprises side channel members and crosspieces on which are mounted rollers, a supporting plate, an endless belt, elongate side members having side portions and a U-shaped portions in which the edges of the supporting plate are disposed, and end cover comprising a cover plate and end cover members which are complementary with and affixed to the side wall portions. The conveyor is mounted on a portable base and has standard control for starting and stopping the conveyor belt.

Abstract: A belt-type separator for effecting separation of blow-molded parts, which separator preferably includes at least two endless belts movably supported on and between a pair of horizontally spaced pulleys, one of which is a drive pulley. The belts, preferably of circular cross section, have the upper reaches extending in parallel but slightly sidewardly spaced relationship to define a small gap therebetween through which scrap parts can pass. The other parts remain on the belts and are transported to a discharge location. The belts are preferably driven at slightly different speeds to facilitate the agitation and dislodgement of the scrap parts so that they can move into and pass through the clearance spaces between adjacent belts.

Abstract: An apparatus for submersing a plurality of elements in a liquid, including an upwardly open tank, a quantity of liquid in the tank, and a perforated plate having a guide surface on the underside thereof and extending from a first location in the region of the surface of the liquid to a second location spaced below the surface of the liquid. A submersion conveyor provided in the tank includes an endless belt having a plurality of spaced and transversely extending cleats, the submersion conveyor being positioned so that, during at least a portion of the path of travel of the cleats, the cleats are adjacent and move along the guide surface from the first location to the second location thereon. Thereafter, cleats on an endless belt of a further conveyor move the elements through the tank below a further guide surface portion on the underside of the perforated plate and then move the elements upwardly and out of the tank.

Abstract: A rotary separator is disclosed which utilizes a rotating drum having a plurality of radially elongated slots therein that lead radially outwardly from a central tumbling chamber. A mixture of molded parts and molding runners is placed inside the central chamber. When the drum rotates, the runners fall through the slots and the molded parts remain within the central chamber.
