Title: Parallel processing apparatus
Inventor: HAMLIN DERRICK J
IPC: G06F9/44
Filed: 1992-01-10
Abstract: ABSTRACT                     (Fig. 1) APPARATUS FOR PERFORMING PARALLEL PROCESSING      A large number of processor cells 11, the majority of which are standard cells 12 and others special cells 13, are connected to a communication network 14 in the form of several binary trees.  The cells 11 are connected at the leaf positions of the binary trees, and the nodes of the binary trees are formed by switching circuits that allow individual cells to control the formation of signal paths through the nodes.  In operation, cells may be in a waiting state, a free state, a calling state, searching state, a communicating state, or an internal operation state.  Cells 12 in the free state transmit a free signal into the network 14.  Cells 12 or 13 in a searching state transmit a searching signal into the network 14 where, on meeting a free signal at a node, a route is formed from the searching state cell to a free state cell.  A calling state cell 12 establishes, with a calling signal, a route through the network 14 to another cell identified by destination information in the calling signal.  Cells 11 in the waiting state are waiting to be called by a cell 12 in the calling state.  Expressions, in the form of lambda expressions, to be reduced to a final result are so distributed through groups of the cells 11 that only primitive operations and communication need be carried out by the cells 11.

Title: Non-invasive device and method for grading meat
Inventor: MICHEL THOMAS E
IPC: G01B17/02
Filed: 1992-06-26
Abstract: ABSTRACT OF THE DISCLOSURE     A non-invasive apparatus and method for measuring fat thickness or content and muscle depth or area parameters grading meat and animals are disclosed.  The device includes an ultrasonic transducer and analyzer device which provides A scan information in digitized form.  A separate controller moves the ultrasonic transducer along a predetermined path adjacent an animal or carcass while A scans are obtained at predetermined locations along the path.  The A scans are digitized and analyzed to determine the tissue interface boundaries.  Equations are implemented to determine the area of the longissimus muscle and fat tissue thicknesses and a lean content rating for the animal may be determined therefrom.  Modeling techniques are also used to estimate certain portions of the area of the longissimus muscle of the animal or carcass based upon data gathered during the ultrasound scanning of the carcass.  Scanning of the ham area and round (beef) using the ultrasonic scanner is also suggested to add increased reliability to the data obtained from scanning the rib or loin eye area when used in conjunction therewith in a leanness prediction equation.

Title: Sausage encasing machine having an improved looper horn
Inventor: TOWNSEND RAY T
IPC: A22C11/00
Filed: 1992-09-09
Abstract: A sausage encasing machine (10) has an improved looper horn (56) thereon mounted to be in communication with the horizontal flow path of encased linked sausages being discharged from the machine.  The looper horn (56) is mounted on a looper horn adapter (36) which rotatably secures the horn for rotation with respect to the  machine about a rotational axis (39) that extend  downwardly from the looper horn adapter (36). The looper horn (56) is connected to a suitable source of rotational power (via 40).  The geometry of the adapter (36) and the looper horn (56) causes the horn (56) to be rotated from a substantially horizontal position of  maximum elevation through a circular continuous arc which is located below the position of  maximum elevation whereby the strand (90) will never have to be moved in an upwardly inclined direction as it passes through the looper horn (56).  The looper horn (56) is U-shaped in cross section and thereupon has an elongated side opening (70) having a discharge axis (74).  The discharge axis (74) is in a lateral direction when the looper horn (56) is in its position of maximum  elevation.  The discharge axis (74) then rotates downwardly as the looper horn (56) moves downwardly on the continuous arc from the position of maximum elevation.

Abstract: A sensor (10) for detecting directional variations in a physical characteristic, fiber orientation angle and the degree of anisotropism of a moving sheet of material is disclosed. The sensor (10) has a support (12) for supporting the moving sheet (14). The support (12) defines an open region into which the moving sheet (14) is deflected by a deflector (16). Detectors (20) coupled to the support (12) detect and produce signals indicative of the force exerted on the support (12) by the deflected sheet in at least three different directions. Alternatively, the support (112) may be rotatable to allow detectors (120) coupled to the support (112) to detect and produce signals indicative of the force exerted on the support (112) by the deflected sheet (114) in a number of different directions. Each signal is processed to determine a physical characteristic, such as extensional stiffness, of the sheet of material in each of the at least three directions.
