Publication number: 20230292699Abstract: In one aspect the invention is a milking platform (1) for a species of animal to be milked, comprising a deck divided into a series of bales (17), each bale having side and end barriers and being of sufficient size to receive only one animal (5) for milking. Each has a structure (2) (e.g. a box) arranged such that when the platform is in use with the animal to be milked the structure (2) extends upwards from the deck to a height below the animal's abdomen, is between the forelegs of the animal, starts in front of the forelegs and extends towards, but stops before, the hind legs of the animal such that there is sufficient space to fit a set of milking cups to teats of the animal.Type: ApplicationFiled: November 5, 2021Publication date: September 21, 2023Inventors: James Pharoah, Caleb Grul, Andy Geissman, Eric Wisse, Christopher Metcalfe, Graeme Mcdougal, Henry Reed, Jamie Mikkelson, Mike Williams, Peter Dowd, Tom Morris

Patent number: 11346759Abstract: A system for testing blade sharpness comprises a mounting arrangement for mounting a material to be cut; a force measuring device operable, in use, to determine variations in force along a blade as parts of the blade contact the material; and a control system. The control system is adapted to receive a signal that a blade sharpness test is to be performed; in response to the signal, prepare the mounting arrangement for a blade sharpness test; detect when force on the material rises above a pre-determined level; detect when the blade sharpness test is completed; and provide an indication of the force of the blade on the material.Type: GrantFiled: February 9, 2017Date of Patent: May 31, 2022Assignee: Anago LimitedInventors: Tim Staub, Peter Dowd

Patent number: 8323359Abstract: A crystallizer system for forming solid crystals includes a vessel defining a cylindrical sidewall, a sparge device located at a bottom of the vessel, a plurality of impellers attached to a shaft, and a plurality of redistribution funnel assemblies vertically spaced apart. Each funnel assembly may be positioned underneath a respective impeller of the plurality of impellers. Each funnel assembly may include a funnel, a disc attached to the shaft such that the disc rotates with the impellers, and a channel extending radially inward from a location near the sidewall. The channel may be adapted to direct gas bubbles from the sidewall to a location near blade outer edges of the respective impeller A lower edge of the funnel and the disc may define a lower gap therebetween, such that solid particles falling from within the funnel are directed out of the lower gap when the disc is rotated.Type: GrantFiled: November 6, 2009Date of Patent: December 4, 2012Assignees: Philadelphia Mixing Solutions, Ltd, Carmeuse Lime, Inc.Inventors: Wojciech Wyczalkowski, Robert W. Higbee, Chris Hibshman, Kevin Smith, Robert Peter Dowd, Carl P. Laird

Publication number: 20070212220Abstract: A variable pitch propulsor system with a propeller pitchlock system having a pitchlock solenoid valve located in communication with a pitchlock pressure circuit to selectively actuate pitchlocking in response to a controller. The pitchlock solenoid valve includes an electro-mechanical device which is normally closed but may be commanded to electrically open and dump the pitchlock pressure which causes actuation of the pitchlock system. The pitchlock solenoid provides a mechanism which will selectively pitchlock the propulsor system; permits a built in test routine to determine the condition of the pitchlock system through a commanded propeller pitchlock sequence; requires no mechanical link between the rotating and non-rotating propeller components to initiate pitchlock; is independent of engine and gearbox configurations; and can initiate pitchlock remotely with a signal from a remote location.Type: ApplicationFiled: March 8, 2006Publication date: September 13, 2007Inventors: Robert Perkinson, Peter Dowd, Paul Carvalho

Publication number: 20070212221Abstract: A variable pitch propulsor system with a propeller pitchlock system which utilizes a follower style pitchlock ballscrew screw which tracks the actuator axial stroke. The pitchlock system transfers the propeller yoke loads, from the ballscrew ballnut to the pitchlock nut allowing the propeller to pitchlock; utilizes the same screw thread lead angle for normal ballscrew back driving operation as well as pitch locking capabilities; provides a single ballscrew which is capable of both being back driven by the ballnut and structurally adequate for reacting the blade loads resulting from any flight condition; and minimizes the requirement of additional rotation and torque transferring interfaces between the ballscrew and pitchlock nut.Type: ApplicationFiled: March 8, 2006Publication date: September 13, 2007Inventors: Paul Carvalho, Peter Dowd

Publication number: 20060201237Abstract: A sharpness tester for testing the sharpness of a blade. The tester has a blade holder 19 and a mounting arrangement 21, 22 for mounting a cuttable material 20. The blade holder 19 is mounted by a carriage 18 which is moveable on a track 14 so that the blade can move relative to the material 20 and contact the material. A linear distance measuring device and a force measuring device 21 enable the tester to determine the force required by part of the blade B to cut the material 20.Type: ApplicationFiled: March 10, 2005Publication date: September 14, 2006Inventor: Peter Dowd

Patent number: 6464227Abstract: A fluid seal having differing fluid levels is provided on opposite sides of a downwardly opening cup-shaped container that is longitudinally lapped by an upwardly opening annular container that is sealed to a vessel such that the lip of the cup-shaped container is submerged. The fluid seal creates a hydrostatic pressure barrier between ambient and a vessel, for example at a rotating vertical shaft. Relatively high speeds are permitted without leakage due to a number of internal horizontal and vertical baffles on one or more walls of the annular container. Barrier fluid losses due to evaporation or the like can be replaced in an embodiment wherein condensed process fluid is used as the barrier fluid, and wherein excess barrier fluid is returned to the vessel while maintaining a differential pressure barrier via the seal.Type: GrantFiled: June 19, 2001Date of Patent: October 15, 2002Assignee: Philadelphia Gear CorporationInventors: Wojciech R. Wyczalkowski, Steven C. Roselle, Robert Peter Dowd, Ronnie G. Thompson, Ravi K. Sharma
