Abstract: A multi-step method is disclosed for efficient selection of antibody or antibody fragments. In addition to the dramatically increased efficiency of finding antibodies against a given immunogen by the invented processes, the novel technology also differs from all previously known technologies in that the antibody or antibody fragments represent the most abundant antibodies induced by the immunogen, therefore having the highest potential of specificity and affinity. Utility of the invention can be found in virtually all areas that involve antibody or T cell receptor selection using any animal, against any immunogen.

Abstract: An improvement in shaft couplings having a flexible elastomeric center element positioned between and bonded to annular metal shoes, which increases the service life of the coupling by forming the elastomer to preferred shapes, contours and thicknesses adjacent a circumferential discontinuity of the shoes and center element.

Abstract: An improved apparatus having a carriage and container which is pivotably connected to the carriage. The container has a cam wheel follower which contacts a cam rail positioned along the path over which the apparatus moves thereby causing the container to pivot. The cam wheel follower is selectively retractable into a housing beneath the container.

Abstract: A system for moving and unloading articles includes a movable carriage having a container which is pivotably mounted upon the carriage and adapted to carry a plurality of loose articles. As the carriage moves toward an unloading station, the container pivots about its axis. During approximately the same time interval, a door which is pivotably mounted to the container is unlatched and pivots toward its open position. Preferably, the time sequence is such that the door is fully opened prior to the container reaching its maximum pivot angle. The pivot angle of the container is greater than the angle of repose on the articles, thereby causing the articles to slide out of the container across the open door and onto a conveyor which forms part of an unloading station. After the articles are unloaded, the carriage moves away, the door is closed, and the container tilts back to its normal position.
