Patent number: 5149445Abstract: A substance is provided in molten form and then converted into crystallized pellets. The pellets are conveyed into a vessel having an open lower end, whereby the pellets continuously advance downwardly. As the pellets advance, they are subjected to a hot gas flow which causes outer contaminated surfaces of the pellets to melt and drip off. The remaining pellets travel out through the opening in a direction transversely of the direction of the dripping. In this manner, the substance is purified.Type: GrantFiled: December 10, 1991Date of Patent: September 22, 1992Assignee: Santrade Ltd.Inventors: Konrad Schermutzki, Herbert Wurmseher

Patent number: 4793787Abstract: A layer of granules is deposited onto a conveyor belt and then heated and pressed to form a final product (e.g., floor covering). The layer is deposited from a funnel having a bottom outlet. Disposed across the outlet are a rotary sizing roll which forms a first gap with the belt, and an inclined guide plate which forms a second gap with the sizing roll. Granules flow through the second and first gaps, and then onto the belt. The second gap is larger than the first gap so that excess granules are supplied to the first gap, thereby assuring that no voids are created in the deposited layer. The guide plate is oscillated to facilitate a back-flow of excess granules to resist the possibility of excess granules being forced through by the sizing roll.Type: GrantFiled: January 21, 1988Date of Patent: December 27, 1988Assignee: Santrade Ltd.Inventor: Konrad Schermutzki

Patent number: 4449448Abstract: In a double band press the compressing pressure is applied to the endless bands by pressure plates via intermediate pressure rolls. The pressure rolls extend transversely to the running direction of the steel bands and are interconnected at their ends by a guide chain. More than two pressure rolls are associated with each pair of connecting bolts of the guide chain. The axes of the pressure rolls are parallel and are offset transversely relative to the axes of the connecting bolts of the guide chain. In this manner, a stable connection of the pressure rolls among themselves is made possible, with the pressure rolls having a smaller diameter and being capable of being arranged closely adjacent to each other. A more uniform and higher distribution of pressure may be obtained thereby.Type: GrantFiled: September 22, 1982Date of Patent: May 22, 1984Assignee: Santrade Ltd.Inventors: Gerhard Stabler, Konrad Schermutzki

Patent number: 4443412Abstract: A crystallizing apparatus particularly for use with undercooled melts. Crystallizing is effected on the cooling conveyor belt in a thick layer. A precrystallizer comprises at least two rolls arranged above the cooling conveyor and rotating in the same direction. A shear gap is formed between the at least two rolls. A melt is applied to an uppermost one of the at least two rolls in a thin layer. In the course of the path followed by the melt over the at least two rolls, shearing forces are generated within the area of the shear gap, which enhance the nucleation. A further enhancement of nucleation is obtained by cooling the at least two rolls, so that relatively large volumes of the melt may be crystallized per unit time in the crystallizing apparatus without the need for the addition of supplemental seed crystals to the melt. The amount of melt in the precrystallizer is very small.Type: GrantFiled: April 1, 1982Date of Patent: April 17, 1984Assignee: Santrade, Ltd.Inventors: Konrad Schermutzki, Wolfgang Weber
