Patent number: 8312966Abstract: A beam anchor. The beam anchor is generally used for attaching to a flanged beam that has been made a part of a structure, to provide fall protection for a worker working on the structure. The beam anchor includes a main cross-member with a beam capturing member at each end. One or both of the capturing members have associated therewith respective yaw restoring mechanisms providing a combined restoring torque for urging the cross-member in counteraction to twisting thereof by a yaw angle in a yaw plane that is substantially parallel to the surface portions. Preferably, a lanyard attachment member is slidably disposed on the cross-member and spring-biased into a relatively centered position between the capturing members.Type: GrantFiled: September 23, 2009Date of Patent: November 20, 2012Inventors: Karl Guthrie, Joseph Schwartz

Patent number: 8225828Abstract: A modular conical chipper/canter head and method. A preferred method adjusts the cutting head for changes in chip length. The method includes the steps of providing an annular facing module, providing a conical, solid hub module for mounting one or more chipping knives, and at least one of (a) installing one or more control plates between the facing module and the hub module, and (b) removing the one or more control plates from between the facing module and the hub module, for spacing the facing and hub modules apart a selected amount.Type: GrantFiled: December 11, 2006Date of Patent: July 24, 2012Assignee: Key Knife, Inc.Inventor: John P. Greiner

Patent number: 8073622Abstract: A long-range lightning detection and characterization system and method. Electromagnetic radiation produced by a lightning strike is sensed at a sensing location and a measured signal representative of the strike is produced that defines an amplitude versus time. A set of reference data containing waveforms comparable to the measured signal is established. The set of reference data defines a set of reference amplitudes versus time, representative of one or more predetermined reference lightning strikes at various predetermined distances, where for each of the distances, the reference lightning strikes have associated therewith various predetermined day/night percentages. The measured signal is compared with the reference data, the comparison including finding a correlation between the measured signal and a correlating waveform in the reference data.Type: GrantFiled: May 12, 2008Date of Patent: December 6, 2011Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Ryan Khalil Said, Umran Savas Inan

Patent number: 8033308Abstract: A double-sided wear insert, for a knife assembly that includes a knife, a clamp, and a holder. In one embodiment, the wear insert can be turned end-for-end, and in another embodiment the wear insert can be flipped up-side down, to double the service life of the part.Type: GrantFiled: January 8, 2007Date of Patent: October 11, 2011Assignee: Key Knife, Inc.Inventor: Bradley R. Stager

Patent number: 7921780Abstract: A projectile (10) comprises a cylindrical body (12) with a first (leading) end (14) and a second trailing axially opposed end (16). An internal cavity (18) is formed between the ends (14 and 16) and holds a volume of propellant material (22). The first end (14) is closed by a nose (20) that is fixed to the body (12). The end (14) is sealed with a base seal (26) that seats a primer (24) for igniting the propellant (22). The primer (24) is located inboard of the second end (16) and the base seal (26) to reduce the likelihood of accidental activation. Seals (30) are formed about the body (12) for maintaining gas pressure of deflagrating propellant. The seals (30) may be formed integrally with the body (12) or separately from the body (12) and seated in respective grooves (40) formed circumferentially about the body (12).Type: GrantFiled: November 10, 2008Date of Patent: April 12, 2011Assignee: Techventure Investments Pty LtdInventor: Leslie Mervyn Harrison

Patent number: 7891388Abstract: A knife and knife assembly for a planer side head. An L or an LV type side planer head is retro-fitted with knives having substantially less mass than the knives originally provided for these heads.Type: GrantFiled: June 29, 2007Date of Patent: February 22, 2011Assignee: Key Knife, Inc.Inventor: Thomas Charles Hinchliff

Patent number: 7836923Abstract: A ring slicer with easily removable knife and knife assembly. According to one aspect of the invention, a ring assembly comprises two end plates for rotation about an axis of rotation. Each of the knife assemblies comprises an elongate knife having a cutting edge extending along an elongate axis, a base, and a clamp for clamping the knife to the base. The knife assemblies are adapted for installation between the end plates such that the shoulder portions of at least two shoulder bolts extend through one of the end plates into the base.Type: GrantFiled: February 26, 2004Date of Patent: November 23, 2010Assignee: Key Knife, Inc.Inventor: Bradley R. Stager

Patent number: 7840250Abstract: A method for neural current imaging. Electromagnetic fields produced unknown distribution of unknown sources in the body is sensed at a plurality of remote locations. The inverse problem is solved to produce a first fuzzy “image” of the sources. In addition, a standard imaging method, such as MRI, is used to independently image the body, to obtain a second fuzzy image of the sources. Additional independently obtained fuzzy images may also be provided. All or a selected subset of the images are pooled as components to form an enhanced image with greater resolution or clarity than the component images.Type: GrantFiled: August 16, 2002Date of Patent: November 23, 2010Assignee: Electrical Geodesics, Inc.Inventor: Don M. Tucker

Patent number: 7798186Abstract: A high speed planer head. Disclosed according to one aspect of the invention is a hub and a threaded member. The hub is axially disposed for rotation about an axis, and has a pocket for receiving a first knife against a supporting wall of the pocket. The threaded member has a frustoconical ramping portion for producing a wedging force against the knife when the threaded member is threaded into a threaded hole in the hub. According to another aspect of the invention, a second hub for carrying a second knife is provided, the second hub preferably being bolted to the first hub to that the hubs can be disassembled. The second knife preferably has two linear cutting edges and the second knife preferably has at least two curvilinear cutting edges and more preferably has four concave, semi-circular cutting edges that are spaced apart from one another with 90 degree rotational symmetry.Type: GrantFiled: April 18, 2006Date of Patent: September 21, 2010Assignee: Key Knife, Inc.Inventor: Bradley R. Stager

Patent number: 7717065Abstract: An aquaculture system (10) comprises one or more tanks (14) that are arranged to be disposed within a body of water such as a pond (12). A reticulation system (16) recirculates water from the pond (12) through the one or more tanks (14). Solid waste material including uneaten food is extracted from the tanks (14) and deposited at a location that is isolated from communication with the pond (16).Type: GrantFiled: June 24, 2005Date of Patent: May 18, 2010Inventor: Ian McRobert

Patent number: 7708040Abstract: A high speed planer head. A threaded member having a frustoconical portion wedges against a knife, to clamp a knife to a hub for rotating the knife about an axis of revolution. The knife has a front and back side, two cutting edges and mirror image symmetry about a mirror plane passing through the knife. To cut both a planar face and two opposed, radiused corners, the cutting edges include respective linear face-cutting portions disposed between two concave, arcuate corner-cutting portions.Type: GrantFiled: February 3, 2006Date of Patent: May 4, 2010Assignee: Key Knife, Inc.Inventor: Bradley R.
