Patent number: 7278824Abstract: A molten material pump includes an impeller housed within a base member of the pump. A plurality of grooves are defined in a peripheral sidewall of the impeller for either drawing a molten material into the base member's chamber or pushing molten material out of the base member's chamber. The impeller is rotated by a rotatable shaft connected to an upper surface of the impeller. The rotatable shaft includes a non-circular shaped lower end dimensioned to be received within a cooperating opening in the impeller. The molten material pump further includes a connecting assembly for interconnecting components of the molten material pump. The connecting assembly includes a first mounting member attached to a first pump component that is dimensioned to be fitted within a cooperating recess of a second mounting member attached to a second pump component. In another embodiment of the invention, a stub shaft connects an upper shaft portion of the shaft to the impeller.Type: GrantFiled: December 14, 2004Date of Patent: October 9, 2007Assignee: Pyrotek, Inc.Inventors: George S.

Patent number: 6921023Abstract: A self-contained water display. The water display includes a cylindrical fountain housing. The fountain housing contains at least one fountain nozzle extending vertically upwardly, and at least one pump adapted to supply water to the nozzle with sufficient volumetric throughput to cause a vertical water stream to be ejected therefrom. A vertically disposed transparent cylindrical cover surrounds the fountain housing with the fountain housing being located in a lower portion of the transparent cylindrical cover. The transparent cylindrical cover has a height above the nozzle that is at least as great as the height of the vertical water stream generated by the fountain nozzle.

Patent number: 6036745Abstract: In a charge well for adding scrap metal pieces or particles to a molten metal bath, a stationary diverter is provided within a charge well for diverting the circular flow of molten metal, caused by the orientation of the inlet port, in a downward direction, thereby creating a downward flow of molten metal which results in quick and efficient submergence of incoming lightweight scrap metal pieces or particles. Preferably, the diverter includes a leading edge which extends in a generally radial direction within the charge well and a flat top surface which tapers from the leading edge to a point or narrowed trailing edge. A downward curved surface extends from the leading edge to facilitate the downward flow of molten metal. The diverter may be mounted on a support member extending above the charge well.Type: GrantFiled: January 17, 1997Date of Patent: March 14, 2000Assignee: Metaullics Systems Co., L.P.Inventors: Ronald E.
