Title: Modified elliptical gear and method for making the same
Inventor: CARR CHARLES F
IPC: F16H35/02
Filed: 1995-01-06
Abstract: A modified elliptical gear defined by a modified elliptical shape having perpendicularly disposed major and minor axes, and bulged portions projecting outwardly beyond the contour of a true ellipse in peripheral regions between the major and minor axes.  A computer is preferably used to rotate a simulated hobbing rack having a row of hobbing teeth around the modified elliptical shape.  The outline of the hobbing rack is traced at selected positions during the rack rotation to produce a profile of a modified elliptical gear with projecting gear teeth.  A topping shape is superimposed upon the gear profile to selectively top the gear teeth. The modified elliptical gear profile is transmitted to a machining means operable to produce a modified elliptical gear.

Title: Attachment Assembly for Excavation Teeth
Inventor: CLENDENNING CHARLES
IPC: E02F9/28
Filed: 1993-01-19
Abstract: An attachment assembly for securing excavation teeth to the loading or dipper bucket on large excavation equipment. The assembly includes a bucket lip adapted to be secured to a loading or dipper bucket, and a plurality of shanks adapted to be secured to the lip and carry the excavation teeth. The lip defines a forward edge extending transversely thereacross and defining a plurality of spaced first curvilinear bearing surfaces. Each of the shanks carried by the bucket lip defines a lateral channel therein adapted to receive a portion of the bucket lip and terminating in a second curvilinear bearing surface. The second curvilinear bearing surface abuts and mates with one of the first curvilinear bearing surfaces on the bucket lip upon shank being disposed thereover. The first and second curvilinear bearing surfaces define equal radius segments of a constant radius circle such that the shank can be aligned parallel to at an angle at up to fifteen degrees with respect to the central longitudinal axis of the bucket lip with the abutting and mating relationships of the first and second bearing surfaces being maintained so as to prevent bearing fracture within the shank during use. The mating relationships of the bearing surfaces defined by the bucket lip and shanks obviate the need to provide differently configured shanks for left, right and central mounting on bucket lips provided with conventional arcuate or spade-shaped forward edges and additionally allows the outer most shanks to be angled outwardly from the central axis of the lip to provide a digging clearance for the bucket.

Title: Method for modulating transendothelial migration of cells promoting inflammation, and related methods of measurement thereof
Inventor: MULLER WILLIAM A
IPC: A61K39/395
Filed: 1994-01-12
Abstract: The transendothelial migration of leukocytes and other cells during acute and/or chronic inflammation can be inhibited by the administration of anti-PECAM-1 reagents. In particular, transendothelial migration appears to be mediated by the activity of platelet endothelial cell adhesion molecule (PECAM); as inhibition of neutrophil and monocyte TEM occurs in the presence of recombinant soluble PECAM or a monoclonal anti-PECAM antibody. Methods for controlling transendothelial migration and corresponding agents are disclosed, as arc related diagnostic methods and drug discovery assays. Inhibition of such transendothelial migration will play a role in the prevention and/or diminishment of organ damage in inflammation, and the present method may be especially useful in the treatment of chronic inflammation, as well as in treating acute inflammation.

Title: Method of coupling ligands within porous supports (p.e. azlactone) and uses thereof
Inventor: VELANDER WILLIAM H
IPC: C12N11/00
Filed: 1994-02-18
Abstract: A method is disclosed for coupling a ligand within a porous support. The method involves mixing ligand and porous support under conditions sufficient to suppress coupling conditions of the ligand to the porous support while enhancing the relative rate of diffusion, to the rate of reaction, of the ligand into and within the porous support, and then altering the conditions to enhance rapid coupling of the ligand within the porous support. The alteration from diffusion conditions to coupling conditions involves a change in the reaction solution of pH, ionic strength, temperature, or coupling competitor, such that a relatively lower Thiele Modulus during diffusion conditions changes to a relatively higher Thiele Modulus during coupling conditions.  Derivatized porous supports produced according to the method are also disclosed. The derivatized porous support has enhanced functional efficiency. Derivatized porous supports prepared from azlactone-functional porous supports are also disclosed.

Inventor: NEWCOMB PETER MICHAEL
IPC: B29C48/31
Filed: 1994-03-17
Abstract: A process and apparatus for producing laminated materials in which one or more polymer films are laminated to a metal strip by a combination of heat and pressure. Generally, polymer films are applied to both sides of the metal strip in a lamination nip which exerts a force of at least 15kN/m. The nip rolls may also be at different temperatures, either by one nip roll being of conducting material such as steel and the other nip roll being of insulating material, or by actively cooling one of the rolls. This enables films having different softening temperatures to be laminated simultaneously without risk of micro-blistering or of pick-up on the rolls.
