Publication number: 20150101691Abstract: A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot and creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.Type: ApplicationFiled: December 15, 2014Publication date: April 16, 2015Applicant: Medora Environmental, Inc.Inventors: Douglas P. Walter, Joel J. Bleth, Willard R. Tormaschy, Corey M. Simnioniw, Jonathan L. Zent

Patent number: 8991422Abstract: A diffuser assembly for a hydraulic reservoir is disclosed. The diffuser assembly includes an inlet tube for connection to the inlet to the reservoir. A middle portion of the middle tube is connected to a plurality of diffusers. The diffusers are disposed at an angle with respect to an axis of the inlet tube and the axis of the inlet to the reservoir so that fluid flowing into the reservoir must change flow directions for entering and exiting the diffusers. The disclosed diffuser assembly is less prone to damaged cause by fluid flow spikes and is particularly useful for high flow/high pressure applications.Type: GrantFiled: July 12, 2012Date of Patent: March 31, 2015Assignee: Caterpillar Inc.Inventor: Bruno Lawrence Risatti

Publication number: 20150079255Abstract: A device for distributing wine uniformly over a wine cap includes a T-joint member, an impeller and a shaft. The T-joint member has a top opening, a bottom opening, a side opening, a through-opening extending from the top opening to the bottom opening and a side-through-opening extending from the side opening to the through-opening. The impeller includes a one-piece conical shaped body that has a circular base, a cylindrical center, a conical-shaped outer surface, a central-through-opening extending through the cylindrical center, and a plurality of curved blades extending from the top of the cylindrical center along the inclined outer surface. The T-joint member is configured to allow wine to be pumped into the through-opening through the side opening and to exit through the bottom opening and then to flow onto the impeller. The impeller is configured to allow the wine to flow uniformly around and down the conical-shaped outer surface of the impeller and through the impeller.Type: ApplicationFiled: September 5, 2014Publication date: March 19, 2015Inventors: ALEXANDER MITCHELL, EVAN SCHNEIDER

Publication number: 20150068606Abstract: A subsea system is for uptake and supply of a liquid. The system comprises a storage tank having at least one outlet, a valve assembly, a pump having a high-pressure side and a low-pressure side, and a feed line. The outlet is in fluid communication with a lower internal volume of the tank, and the valve assembly. The low-pressure side of the pump and the feed line are in fluid communication with the outlet, and the valve assembly is arranged on the feed line, and the feed line is bypassing the pump, such that said pump may withdraw liquid from the tank when the valve assembly on the feed line is closed.Type: ApplicationFiled: September 12, 2012Publication date: March 12, 2015Applicant: OBS TECHNOLOGY ASInventor: Nils Terje Ottestad

Publication number: 20150017332Abstract: An apparatus and method for supplying virgin sealer and reclaim sealer to a sealer applicator. A closed loop path including a first fluid flow path is coupled between a source of virgin sealer and the applicator and includes a recirculation path from the applicator back to the source of virgin material.
