Abstract: A two PROM coherent optical processing system under computer control provides zoom of the input object, rotation of the filter PROM relative to Fourier transform of the coherent light image, serial painting of the spatial filter on the filter PROM using a digitally controlled laser scanner, and greater operator control of the filtered image using a digital video processor and the associated computer.

Abstract: A coating composition, comprising an aqueous dispersion of a pigment such as clay and a binder such as a latex of a copolymer of styrene and butadiene thickened with a water-soluble copolymer of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid such as acrylic acid, an ethylenically unsaturated carboxamide such as acrylamide and an ethylenically unsaturated monomer having limited solubility in water such as acrylonitrile, is effectively employed in coating paper and other cellulosic web materials.

Abstract: A process for manufacturing synthetic hydrocarbons such as gasoline and/or kerosene from the synthesis of carbon dioxide and hydrogen. The carbon dioxide is obtained from the atmosphere while the hydrogen is obtained during the electrolysis of water. An intermediate fuel, namely methyl alcohol may be stored for use or upgraded to higher heating value hydrocarbons by a catalytic conversion.

Abstract: A thermal detection and alarm system for indicating the irradiation of a surface by a heat source such as a laser beam has been invented. The detector element may form an integral portion of the vehicle's outer surface or may be parasitically mounted thereto. The proposed system is light weight, energy efficient, durable and highly sensitive. The invention is especially suited for use with Boron-Tungsten composite surfaces as found on aircraft and spacecraft.

Abstract: A two piece pull-type fastener is disclosed herein comprising a pin and collar adapted to be swaged into locking engagement with the pin upon setting of the fastener by application of a pulling force to the pin and reaction force on the collar. The pin is provided with a minimum number of pull grooves defined by alternating crests and valleys which grooves are sufficient in strength to allow an installation tool to exert a pulling force on the pin of a magnitude required to properly set the fastener. The installation tool has a gripping structure adapted to engage the pull grooves. The gripping structure and pull grooves are complementarily shaped so as to prevent engagement of less than all of the pull grooves by the gripping structure of the tool in order to prevent stripping of the pull grooves if less than all are attempted to be engaged. Thus an installation tool nose assembly is also disclosed which nose assembly is uniquely designed for use with the present fastener.

Abstract: The embodiment of the invention disclosed herein is directed to a record selector mechanism which includes a plurality of spaced-apart records to be individually selected and played by a transducer. The plurality of spaced-apart records are secured by coupling means to a common support shaft element and simultaneously rotated at playing speed. A transducer member is secured to a transport mechanism to be positioned adjacent the record to be played. The transport mechanism includes means for urging the transducer in either one of two directions so as to engage a selected one of diametrically opposed record surfaces which are rotating. A slide pointer is mounted at the exterior of the housing and movable along a linear path and adjacent spaced-apart indicia. The indicia identifies the records within the phonograph system and the pointer is used to select the desired record. The slide mechanism includes an actuator to be manipulated when the slide is adjacent indicia corresponding to the desired record.

Abstract: A Vertical Takeoff and Landing (VTOL) aircraft that has a small stowage envelope made possible by articulation of the aircraft empennage and fuselage, the aircraft having propulsion units capable of providing in all attitudes of the empennage with respect to said fuselage engine wash of the empennage thereby insuring aircraft control without additional reaction stabilizing units.
