Abstract: The present teaches new method and apparatus for evaluating ultrasonic images of muscle of an animal or carcass. Method and apparatus are taught for recognizing muscle interfaces of an animal or carcass from an ultrasonic image of a muscle area. Method and apparatus are taught for determining marbling scores of a muscle of an animal or carcass from an ultrasonic image of the muscle. Method and apparatus are taught for detecting an outline of a muscle from an ultrasonic image of an animal or carcass.
Abstract: The present invention includes method and apparatus for grading a poultry carcass intended for human consumption. An ultrasound machine is provided which includes a probe for transmitting and receiving ultrasound signals such that the machine is capable of producing a image of a breast muscle of the carcass. The probe is positioned on the carcass parallel to the keel such that the image of the breast muscle of the carcass is detected by the ultrasound machine. A breast muscle size indicator of the breast muscle is determined from the detected image. The calculation of a grade for the carcass is based upon the ratio of the indicator to the weight of the carcass. The determination of the breast muscle size indicator can be performed by an image analyzer and pattern recognition equipment modified to recognize the breast muscle image. The probe can be positioned automatically by probe location equipment automatically.
Abstract: A pivoting keel guide for boat trailers which can be used with most boats, can be easily field added to existing trailers, and which will provide excellent centering action for crosswinds when the trailer is submerged. A base plate attaches to a cross-member of the trailer. Pivotally attached to the base plate is a U-channel guide arm, with a pair of guide rollers supported on roller arms mounted on the end of the guide arm opposite the pivot. The guide arm is biased into a raised position using resilient elements such as springs, so that the guide rollers can contact the bottom of the boat while the trailer is submerged. The guide arm pivots along the length of the trailer as the boat settles onto the trailer, exerting a constant centering force.
Abstract: A method is provided for protection of biological materials from the stresses of air-drying and also from destructive reactions, such as oxidation and free-radical attack, which degrade the materials during long-term storage. The method involves drying the materials, which may contain potentially destructive agents such as free-radical generators or reducing sugars, in the presence of a vitrifying substance, and under conditions which allow the protective substance to become vitrified.

Abstract: A mud valve having a plug seat which is made of a resilient material, and which forms the seal at an angle of approximately 28.degree. from the vertical. The valve seat is formed with a matching 28.degree. inclination to mate with the resilient seat.
Abstract: An improved apparatus for sorting agricultural products such as vegetables or fruits from dirt clods, rocks, or other debris, without bruising the desired product. The mixture of desired product and undesired debris is transported by conveyor and allowed to fall freely on a rotating roller. The individual components rebound differentially from the roller, separating the product and the debris. The roller is constructed of a loose-fitting sleeve supported and rotated by resilient disks on a rotating shaft, with the resilience of the disks minimizing the bruising of the product rebounding from the roller.
Abstract: A 2-dimensional drawing of closed shapes and/or letters is processed for incised carving with a conical tool. Each closed shape is processed independently to generate a plurality of connected cutter paths. While carving each path it is necessary to change the tool depth so that the edge of the tool at the surface of work remains tangent to two sides at all times. A recursive process is used to handle parts of the work where the cutting path splits.
