Publication number: 20140008560Abstract: An continuous meat grinding reclaiming system that comprises a primary meat grinder unit and a secondary meat grinding unit for continuously and simultaneously processing a meat batch in a single processing run. The primary meat grinder unit is designed to grind a batch of meat by initially separating or extrapolating pure meat from the meat that contains bone; collecting the pure meat into a container; and transferring the meat that contains the bone to the secondary meat grinder unit. The secondary meat grinder unit is designed further grind the batch of meat by separating additional pure meat from the meat that contains the bone; collecting this additional pure meat into the container with the original pure meat; and discard any remaining “undesirables”. The meat grinding reclaiming system also provides an inventive variable valve reducer for controlling the flow of the undesirables through the secondary transfer pipe.Type: ApplicationFiled: September 12, 2013Publication date: January 9, 2014Inventor: Jerry York

Patent number: 8622010Abstract: A pneumatic seacock retrofit is provided for convenient closing of all or a portion of the seacocks, whether as a matter of every day convenience or for use in an emergency, in which all of the vessel's seacocks can be pneumatically closed at the same time, leaving the possibility of selectively overriding seacock closure, with all control valves operating to provide a momentary pulse of air to the rotary actuators and then return to a neutral position, leaving the actuators free for further control. Moreover, an operator is free to manually close a valve in the event that the pneumatic system fails.Type: GrantFiled: November 8, 2011Date of Patent: January 7, 2014Inventors: Seth Joseph Gray, Edward Joseph Gray

Publication number: 20130334448Abstract: A device for a valve has a fixed part provided with at least one fluid port and a rotatable sleeve provided with at least one bore. The sleeve is structured in a manner allowing it to rotate the bore in-line with the fluid port in order to allow a fluid to flow through the fluid port and the bore when the sleeve is in an open position. The sleeve is structured in a manner allowing it to rotate the bore away from the fluid port in order not to allow a fluid to flow through the fluid port when the sleeve is in a closed position. The fixed part and the sleeve form an annulus between the fixed part and the sleeve. The annulus is restricted axially by two packer elements in the axial directions of the sleeve and the fixed part, wherein one of the two packer elements is located at one side of the fluid port, and the other of the two packer elements is located at the opposite side of the fluid port, and wherein the annulus is in fluid communication with the fluid port of the fixed part.Type: ApplicationFiled: February 8, 2012Publication date: December 19, 2013Inventors: Lars Gunnar Hodnefjell, Helge Sverre Eide

Publication number: 20130276520Abstract: A valve includes a stator that has fluidic ports in a seal surface, and a rotor that has a seal surface contacting the stator's seal surface. The rotor has through-holes that extend from the seal surface to a back surface, providing fluidic communication with a conduit disposed adjacent to the back surface of the rotor. A chromatography apparatus includes a sample source, a solvent source having a higher operating pressure than the sample source, and an injector valve. A method of performing chromatography includes loading a sample with a valve in a load-state configuration that disposes a sample source in fluidic communication with a conduit disposed adjacent to a back surface of the rotor, and injecting the loaded sample with the valve in an inject-state configuration that disposes a solvent source in fluidic communication with a column via at grooves adjacent to a front seal surface of the rotor.Type: ApplicationFiled: April 6, 2011Publication date: October 24, 2013Applicant: WATERS TECHNOLOGIES CORPORATIONInventor: Mark W.
