Abstract: ABSTRACT:            The device in accordance with the inven-tion consists of interconnected disks of piezoelec-tric material, at least one disk having a ferro-electric transition temperature. A metal foil is provided between the said disks. Mutually parallel, conductive strips are provided on both outer sur-faces of the assembly thus formed. The direction of the strips on the one surface differs from that of the strips on the other surface. A generator for periodic signals which can be sequentially connec-ted to each strip on one of the surfaces of the first disk generates therein, via  a piezoelectric effect, ultrasonic vibrations which are intercepted by the other disk which converts these vibrations into electric signals. These signals are amplified and carry the image to be examined.

Abstract: PROCESS AND COMPOSITION FOR PRODUCING AND   MAINTAINING GOOD COLOR IN FRESH MEAT, FRESH POULTRY AND FRESH FISH    By Richard E. Woodruff and John H. Silliker ABSTRACT           Good color in fresh meat, fresh poultry, and fresh fish is established and maintained by subjecting such meat, poultry and fish to an atmosphere containing a low oxygen concentration to convert oxymyoglobin on the surface of the meat and poultry to reduced myoglobin, and both oxymyoglobin and oxyhemoglo-bin in fish to reduced myoglobin/hemoglobin, respectively, then subjecting the fresh meat, fresh poultry and fresh fish to a modified atmosphere containing a small amount of carbon monoxide to convert the reduced myoglobin to carboxymyoglobin to a depth of not more than about 0.375 inch below the surface of the meat and poultry, and to convert the reduced myoglobin/hemoglobin to reduced carboxymyoglobin/carboxyhemoglobin in the fish.    The modified atmosphere is a new composition of matter.           During or after the conversion, the fresh meat, fresh poul-try and fresh fish may be maintained at temperatures above freezing in an atmosphere that contains more than about 10% carbon dioxide by volume to inhibit bacterial growth or alternatively, the fresh meat, fresh poultry and fresh fish may be frozen and maintained frozen in normal air atmosphere.

The first element supports a pair of axially movable cone-like members fixed for rotation with the first element and each having exterior surfaces of revolution defined by a curved generatrix to be convex in axial section and converg-ing away from the point of first and second element axes intersection.  The rolling friction surfaces of the second element are defined by an interior cylindrical surface and means are provided for adjusting the angle of the second ele-ment axis with respect to the first to vary the radii at the point of frictional contact on the cone-like members.  Angular adjustment of the second element axis with respect to the axis of the first element is accomplished in a preferred embodi-ment by fluid activators for adjustably eccentric journals on a third or support element, such journals being movable in diametrically opposite directions at opposite ends of the second element.  Alternately, the angular adjustment is accomplished by an eccentric sleeve-like member carrying the second element in the support member.  Input torque is preferably provided by a clutch to the support member whereas the variable speed output is desirably transmitted through a multi-speed gear transmission.

Abstract: Abstract of the Disclosure Disclosed is an automatic video intrusion detection syste.  The system monitors a given area such as between two parallel fences.  The image of the given area is divided into an array of cells each approximately equal in size to the image of a man.  The video for each cell is integrated, digitized and stored in an array.  Changes in cell values arc detected and tracked so that changes in, say, 3 adjacent cells in a given direction, indicate an intruder. A microcomputer implements a tracking algorithm.  Filtering discriminates against light level changes.  The system is simpler than a known one which analyzes grey values of thousands of points in a video field.
