Title: Middle splitter with caterpillar driving system
Inventor: DUFOUR YVON
IPC: A22C17/00
Filed: 1997-02-14
Abstract: A middle splitter for use to split an animal's middle into two parts. The splitter has a work table and a conveyor belt to move the middle forward. The splitter also has a circular saw which extends in a longitudinal slot in the conveyor belt. A guide extends from upstream down to the saw. This guide is parallel and extends above the conveyor belt in order to hold the middle against it. The splitter further has a caterpillar drive which extends before and past the saw. The drive is parallel to the conveyor belt and has a contour belt mounted onto a support of longitudinal shape. The contour belt has protruding plates shaped and positioned to engage the middle.  The conveyor belt is driven  into rotation by a shaft connected to a motor, so that the side of the contour belt nearest the saw moves forward. As a result, when the motor rotates the belt, the drive pulls the middle forward toward the circular saw for it to be cut. A pressure device is provided to push the drive towards the guide to push on the spine and straighten it up while the middle is cut.

Title: Engineering plant thioesterases and disclosure of plant thioesterases having novel substrate specificity
Inventor: YUAN LING
IPC: C12N15/09
Filed: 1996-05-15
Abstract: Methods of altering substrate specificity of plant acyl-ACP thioesterases, and engineered plant acyl-ACP thioesterases so produced are provided. The C-terminal two-thirds portion of plant thioesterases is identified as desirable for such modifications.

IPC: A61D19/02
Filed: 1996-12-18
Abstract: Pipettes for infusing the uterus are disclosed, each pipettes being generally comprised of a proximal end, a mid-section and an enlarged distal tip. The proximal end has a coupling portion for engagement with a fluid-expressing syringe. Distal tips disclosed are of two primary shapes, one having a generally hemispherical distal zone of expanding diameter in a distal to proximal direction; and, another having a generally frusto-conical distal zone, with a similarly expanding diameter.
