Lens assemblies are provided for each eye image to provide a horizontal spread of between 40.degree. and 60.degree. which substantially matches the natural horizontal field of vision. The convergence of the first and second axes is adjustable. The camera may be provided with a viewfinder in which the left and right eye images are separated out again.

Abstract: A land rescue vehicle equipped to safely recover wounded or injured personnel or valuable equipment while under hostile fire is disclosed. A self-propelled vehicle is equipped with an armored body shell which extends downwardly to near ground level and substantially encloses the vehicle wheels to form a shielded space beneath the vehicle. An entry panel forming a portion of the vehicle shell at the front of the vehicle is selectively opened and closed to permit positioning the vehicle over an injured person and within the shielded space. Trap doors in the floor of the vehicle body provide passage from the shielded space to the safety of the interior of the vehicle for transport of the rescued person.

Abstract: Pancreatic exocrine function is determined by a breath test method wherein a radioactive labelled ester such as cholesterol octanoate is ingested in the body and is hydrolyzed by pancreatic enzymes and oxidized to labelled Co.sub.2 which is expired in the breath. The rate of appearance of labelled Co.sub.2 in the breadth is a function of the rate of hydrolysis by pancreatic enzymes which in turn reflects pancreatic exocrine function. Before ingestion, the ester is mixed with a carrier substrate such as a triglyceride to form a lipid matrix containing the ester and the lipid matrix is suspended in aqueous solution. To insure that low levels of expired labelled Co.sub.2 is due to pancreatic exocrine insufficiency, the ester is ingested simultaneously with a differentially labelled unesterfied carboxylic acid or the test method is repeated with an added step of simultaneously ingesting the ester with exogenously provided pancreatic enzymes.

Abstract: Secure placement of confidential information on tickets distributed in blank is permitted by opaquely overlaying an area of the ticket upon which the information is to be placed in visible form and employing a printing apparatus that prints the visible information on the ticket area through the opaque overlay without leaving any easily-discernible trace in the overlay that reveals the imprinted information. A ticket can be given in blank to a ticket holder. Then, when the ticket holder makes an exchange in order to receive the information, the information can be placed on the ticket, with the opaque overlay concealing the information until selectively removed by the ticket holder.

Abstract: A method for crushing metal cans into rectangular blocks or bales wherein cans are fed through a precrusher, which flattens and rips open the cans to drain liquids therefrom and leaves protruding torn tabs and flaps that facilitate bonding of the cans into a self-sustaining bale. The flattened cans are collected in a charging bin until a predetermined weight is reached; then the cans are released into a bale-forming chamber, which is closed by a hinged door forming an initial compression member. A ram then compresses the cans longitudinally in the chamber, the ram having ribs on the compression face to form grooves in the bale for future stack-retaining straps. A sliding door opens the end of the baling chamber for ejection of the formed bale by continued extension of the ram.

Abstract: A video signal producing a raster-scanned image is processed in real time to enhance high frequency characteristics of the image generated by the signal, with the enhancement performed according to a local adaptive process implemented in an apparatus including one or more two-dimensional higher-order filters. Each filter provides a signal corresponding to a statistical measure of the raster image at a point in the image centered in a local area. In each case, the measure is a function of characteristics of the image within the centered area. Each filter is synchronized with the video signal to provide its respective statistical signal substantially in real time and in phase with the input video signal.
