Each work piece support member has a sprocket mounted on its radially inward end and is shaped so as to receive a work piece in its radially outward end.

Abstract: A kiln or oven for producing ceramic products is described having a combustion chamber through which the ceramic products continuously pass, as well as a process for the operation and control of the kiln and the ceramic products perform a rotation about their own longitudinal axis in addition to the passage movement through the combusion chamber. The passage and rotation of the ceramic products takes place by means of a drive mechanism located in the kiln base with shafts projecting into the combustion chamber and located on an inventively designed receiving and holding device and can be regulated in infinitely variable and separate manner. The invention permits an effective, discontinuous operation of the kiln.

Abstract: Heated surrogate medium is placed in heat transfer relation with high moisture content waste material where water is evaporated to steam. By agitating the mixture of waste material and heated surrogate medium, particulate matter from the waste material is entrained in the steam. A separator separates the steam and dried waste material and supplies the dried waste material to a burner for heating the surrogate medium. The separated steam flows to a stack or to the surrogate medium and oversized waste material discharged through an outlet of the drying zone for flowing additional particulate material from the waste material flowing through the discharge outlet back into the drying zone. The discharged surrogate medium and the oversized waste material are separated and the separated surrogate medium is recycled into the heating zone.

Abstract: Apparatus is disclosed for heating a plurality of sheets of plastic material between adjacent ones of a plurality of vertically stacked and individually heated platens. The platens are vertically displaceable together and relative to one another, and any two vertically adjacent platens are vertically separable relative to a fixed horizontal pass line to facilitate removing a heated plastic sheet from between the platens and introducing a plastic sheet to be heated therebetween. Vertical separation is achieved by latching the upper one of two adjacent platens in a fixed holding position above the pass line and lowering the lower one of the two platens and any other platens of the stack therebeneath to position the upper surface of the lowered platen at the pass line. Sheet discharge and feed mechanisms are then operable respectively to remove a heated sheet from the lower platen and introduce a sheet to be heated onto the lower platen.
