Title: Barb clamp
Inventor: WERTH ALBERT A
IPC: F16L33/22
Filed: 2002-05-24
Abstract: A barb clamp provides a leakproof connection of a flexible tube in a barbed fitting. The barb clamp includes a collet and sleeve. The barb fitting is configured to fit snugly within the tube. The collet is slid over the tube.  Shelves on the interior surface of the collet fit tightly around the tube and under an expanded portion of the barb fitting. The sleeve is then slid over the collet. As the sleeve moves over the collet, tangs on the collet are pushed radially inwardly into the tube and barb fitting. The sleeve is moved over the collet until an annular projection on the interior surface of the sleeve sits within an annular groove of the collet. Radial ledges on the exterior surface of the collet provide a stop and lock to prevent the annular projection on the sleeve to move out of the annular groove of the collet.

Abstract: In a process and apparatus for determining grading parameters of a carcass, the outline of an image of the carcass is traced and reference points representing anatomical features of the carcass are identified. Second reference points being located at pre-determined positions relative to the first reference points are then identified. The carcass image is divided into sections, the boundaries of each section being determined as a function of the position of the first and second reference points, and the area of each section is determined. A grading parameter predictive equation is determined wherein the grading parameter is included as a dependent variable, and at least one area of a carcass image section is included as an independent variable. Solving the predictive equation provides a value for the grading parameter of the carcass. Other measurements can be obtained from the carcass image and used as independent variables in predictive equations.
