Patent number: 10876536Abstract: A compressor includes impellers each having its chord angle less than its stall angle. The impellers can be used in a contra-rotating impeller arrangement without static diffusers. The contra-rotating impeller arrangement provides for much larger nominal flow rates than conventional single rotating impeller arrangements with the same chord angles. Accordingly, a surge free design is provided without excessively compromising the nominal flow rate. Techniques for enhancing stall characteristics of the impellers are also described.Type: GrantFiled: July 23, 2015Date of Patent: December 29, 2020Assignee: ONESUBSEA IP UK LIMITEDInventor: Bernt-Helge Torkildsen

Patent number: 8894272Abstract: An agitator 1 has a vessel 4 provided between an upper powder/particulate material supplier 2 and a lower powder/particulate material discharger 3 to hold therein powder/particulate material to be stirred. The agitator 1 also has a stirrer 7 provided in the vessel 4 to have a stirrer rotating shaft 5 arranged in a horizontal direction and main paddles 6 fastened to the rotating shaft 5, and a multi-feeder 8 provided in the powder/particulate material discharger 3 to have both forward rotation and reverse rotation. The multi-feeder 8 has a discharger rotating shaft 81 and small-size auxiliary paddles 9 integrally rotated with the rotating shaft 81 and designed to be smaller in size than the main paddles 6.Type: GrantFiled: September 1, 2010Date of Patent: November 25, 2014Assignee: Tsukasa Co., Ltd.Inventor: Fumio Kato

Patent number: 8616762Abstract: An automatic pot stirrer is provided that has a mount assembly. The mount assembly is mounted on a pot plate having slider clamps. The slider clamps engage the rim of the pot and are designed to accommodate differently dimensioned pots. The mount assembly supports a shaft that is operatively coupled to a motor at one end and threaded to a block at the other end. The block has opposed first and second block end walls and opposed first and second block paddle walls to which are connected paddles. The first and second block paddle walls may be disposed at about a forty-five degree angle to a second block end wall. The paddles are disposed at about a forty-five degree angle to the second block end wall such that the paddles lift food product from the bottom of the pot during operation of the automatic pot stirrer.Type: GrantFiled: February 6, 2013Date of Patent: December 31, 2013Inventor: William H. Swader

Patent number: 6457853Abstract: An impeller for use in a mixing apparatus having a rotating shaft has at least one longitudinal member extending substantially radially from the shaft; and a plurality of individual impeller segments each having a bore therethrough. The segments are stacked together with the longitudinal member extending through said bores. The longitudinal member may be an at least partially threaded rod or may be a beam. A method of assembling an impeller for use in a mixing apparatus having a rotating shaft employs the steps of stacking a plurality of individual impeller segments onto a longitudinal member that extends substantially radially from the shaft; and fastening the stacked impeller segments onto the longitudinal member to retain the impeller segments on the longitudinal member.Type: GrantFiled: December 29, 2000Date of Patent: October 1, 2002Assignee: SPX CorporationInventor: David Engel

Patent number: 6250797Abstract: An axial flow mixing impeller system for efficient mass transfer by control of size of the bubbles of the fluid which is being dispersed, especially gases and liquids with viscosities greater than the liquid into which dispersion occurs, is obtained by creating passageways through the impeller blades for flow between the suction and pressure sides of the blades which disrupts the flow over the suction sides of the blades thereby reducing the tendency for bubbles to grow or coalesce into large bubbles which instead of being dispersed, rise to the surface without effective mass transfer to the liquid which is pumped by the impeller. The blades of the impeller may be slotted inwardly from the tips thereof to provide the passageways or may be formed from segments, gaps between which provide the flow passageways.Type: GrantFiled: October 1, 1998Date of Patent: June 26, 2001Assignee: General Signal CorporationInventor: Ronald J.
