Patent number: 7190088Abstract: The process of attaching turbines to water mains, water towers, sewage lines, aqueducts, and various pipelines so as to capture the kinetic energy of pressurized fluid traveling through these mediums and changing the kinetic energy to electric energy by means of a generator and conducting this new electricity to the nearest power substation by means of a conduction pipe. By consumer demand for utilities such as water and sewage to be taken to and away from homes and businesses, these consumers will be making their own electricity that they will then buy back from the utility companies. With more and more people buying homes and starting businesses, there will be many new utility consumers on top of the already existing consumers, which means that the potential and scope of using the process for making cleanly generated electricity is limitless and universal.Type: GrantFiled: May 7, 2004Date of Patent: March 13, 2007Inventor: Robert Eric Heidel

Publication number: 20030091425Abstract: The present invention relates to an improved fluid handling system including an improved collection trough and pump assembly. A centrifugal pump is mounted in the path of cutting fluid that needs to be pumped from a collection system and discharged. A wide and narrow inlet mouth lies very low on the factory floor enabling the centrifugal pump to be mounted right on the floor and not within the floor. An optional vacuum system provides suction within the centrifugal pump that aids in priming the pump at start up and in removing air from a pump chamber within the pump, thus allowing more efficient pumping to take place. An impeller rotates within the pump creating a vortex within the pump chamber which facilitates movement of dirty cutting fluid including metal particles to be pumped through to a discharge outlet.Type: ApplicationFiled: March 19, 2001Publication date: May 15, 2003Applicant: Steven McEwenInventors: Stephen N.

The mixture is worked and pressed out through an outlet (30) by wing-like elements (11) carried by the rotor.Type: GrantFiled: August 15, 1989Date of Patent: February 4, 1992Inventor: Nemo Ivarson

Patent number: 5049031Abstract: The present invention provides a system for facilitating the removal of the lantern ring and packing in pump assemblies. Previously a steel hook was used to scrape away the worn packing. The present invention provides a series of cables extending through the lantern ring which permit the lantern ring and packing to be easily pulled out when replacement is required.Type: GrantFiled: May 8, 1990Date of Patent: September 17, 1991Assignee: Zee Impeller Breaker Inc.Inventors: William Mintenko, Frank Protz

Patent number: 5044883Abstract: A water pump for an internal combustion engine is provided comprising a pump holder and a pump block. The pump block includes a pump mount having a shaft passing therethrough terminating in an impeller. The pump block is mounted to the holder via a quick release, bayonet type coupling with the pump mounted sealed to the holder. A snap fitting locking ring locks the block to the holder and prevents disconnecting the coupling by blocking reverse rotation of the block relative to said holder.Type: GrantFiled: September 21, 1989Date of Patent: September 3, 1991Inventor: Ludwig Neueder

Patent number: 4979872Abstract: The support structure for the bearing compartment for a gas turbine engine includes eight radial tie bolts connected with the clevis wherein the outer diameter clevis is connected to the mount ring with an accessible bolt for easy assembly and disassembly. The tie bolts, while preloaded in tension, can accept compressive loads during severe loading operation conditions. The turbine exhaust case housing the tie bolts and bearing compartment are designed to facilitate cooling and maintainability at reduced costs.Type: GrantFiled: June 22, 1989Date of Patent: December 25, 1990Assignee: United Technologies CorporationInventors: Richard S. Myers, Perry P. Sifford

Patent number: 4976585Abstract: A system for the rapid balancing of revolving shafts, in particular, the revolving shaft of a gas turbine. The system comprises two mutually adjacent bores provided in the stator of the turbine, which can be closed by relevant plugs, and which are collimated on the screw-threaded bores of the rotor. The system also comprises a special rigid rod for elastically holding a screw-threaded balancing mass, and for causing it to rotate.Type: GrantFiled: April 3, 1989Date of Patent: December 11, 1990Assignee: Nuovopignone-Industrie Meccaniche e Fonderia S.p.A.Inventors: Vasco Mezzedimi, Franco Frosini

Patent number: 4955789Abstract: A duplex turbine replacement unit to up-grade an obsolete or worn out quad turbine unit and thereby obtain enhanced power plant operational and output efficiencies, while at the same time providing a turbine profile and method of installation wherein the duplex turbine replacement unit hereof conveniently adapts to utilizing the existing draft tube discharge floor holes as originally provided for the replaced quad turbine unit draft tube discharges thereby eliminating the extensive and expensive civil engineering site modification and re-work that would otherwise be necessary with conventional commercially available up-grading replacement turbine units, in addition to also providing a turbine replacement unit having an internally housed and protected wicket gate adjustment mechanism which thereby substantially reduces the hazard of damage thereto by entrained debris in the turbine water.Type: GrantFiled: April 24, 1989Date of Patent: September 11, 1990Assignee: American Hydro CorporationInventors: Selim A. Chacour, William H. Colwill

Patent number: 4932836Abstract: A pump having a heat exchanger including a rotating baffle sleeve secured to the pump shaft. A seal baffle on the rotating baffle sleeve extends over the pump seal assembly cartridge. A cooling cylinder containing circulating component cooling water is suspended within the rotating baffle sleeve and defines a flow passageway therein for cooling heated product water, before the product water contacts the shaft seal. A seal injector distributor ring uniformly distributes seal injection water to the seal. A thermal shield in the heat exchanger reduces thermal stresses in the heat exchanger. A slotted or grooved keyway spacer ring facilitates replacement and alignment of a hydrostatic bearing.Type: GrantFiled: May 11, 1989Date of Patent: June 12, 1990Assignee: BW/IP International, Inc.Inventor: Clark S. Boster

Patent number: 4927323Abstract: A radical flow mechanism is provided having a symmetric housing assembly defining a hollow rotor chamber. A symmetric shaft and rotor assembly is supported for rotation in the rotor chamber. A plurality of radial flow paths are defined by the rotor and the housing assembly. The assembled module may be powered by a pressurized motive fluid that flows radially inward to rotate the rotor. Alternatively, the rotor may be driven by an external power source so that a working fluid increases in potential energy as it moves centrifugally outward. The assembled module is symmetric about the rotor member so that the rotor can be orientated for either direction of rotation and so that power takeoff or power connection can be to either side of the module. Also, the module is constructed so that the seals are located at an interface having a low pressure differential and the bearings are located adjacent an area encouraging heat dissipation.Type: GrantFiled: December 28, 1988Date of Patent: May 22, 1990Assignee: Ingersoll-Rand CompanyInventor: Robert R. Kimberlin
