Abstract: A PROCESS AND APPARATUS FOR PRODUCING A BIAXIALLY        ORIENTED ACRYLONITRILE POLYMER FILM            Abstract:          Continuous production of a biaxially oriented acrylonitrile polymer film includes stretching a strip of an aquagel film of the polymer in the longitudinal direction of the strip, then stretching the strip in the transverse direction and subsequently drying the biaxially oriented strip.  In order to improve the thickness uniformity of the resultant film, water is added and/or substracted from specific longitudinal regions of the longitudinally stretched aquagel strip selectively to alter across the width of the strip its resistance to transverse stretching.

Abstract: ABSTRACT   An optical cursor control device or "optical mouse" is disclosed for use with an interactive, display oriented computer system to provide movement for a visible cursor from position to position on a display screen of such a system. The cursor control device provides an output indicative of the amount and direction of movement of the device relative to an orthogonal coordinate system. The device relies on a planar grid pattern comprising orthogonally positioned grid lines of uniform spacing, one line and spacing defining a grid period. Means is provided to illuminate at least a portion of the grid pattern. Sensor array means comprising optical transducers are provided for each orthogonal direction. Each optical transducer has an elongated radiation detecting area to receive radiation from an elongated radiation collecting area at the plane of said grid pattern. The length of the radiation collecting area of each transducer is equal to or greater than a grid period and the width of these areas is equal to or narrower than the width of one half of the grid period.

Abstract: Mixing Apparatus Abstract The mixing of liquids and liquid suspensions in vessels is obtained by a mixing impeller mounted on a shaft and rotated by a drive which delivers selected speed and torque.  The torque and power needed to obtain given flow is minimized by a low-cost impeller having a plurality of blades, each formed from a plate of constant thickness except for a leading edge of rounded profile.  Each blade has camber which decreases from the tip to the base thereof.  The base can be flat to facilitate the attachment of the blades to the shaft. The blades are oriented and twisted to be at the threshold for flow separation along the width of the blades from the leading to the trailing edge thereof, thereby providing maximum flow in the axial direction before the onset of flow separation.  The orientation and twist of the blades provides a generally constant angle of attack along the entire blade from tip to base and the planform of the blade provides for uniform load-ing, stability and minimization of fluid forces which tend to bend the shaft.

Abstract: Abstract A procedure is described for producing semiconductor devices having damage-free surfaces in electrochemically n-type and intrinsic compound semiconductors.  The process involves a photoetching procedure including applying a potential to the compound semiconductor while it is in contact with an electrolytic solution and irradiating the surface to be etched with light in a certain energy range.  By suitable adjustment in the potential, electrolytic solution composition and light energy, the etch rate is made proportional to the light intensity.  By suitable variation in light intensity and light-ray direction, various geometrical features can be made on the surface of the compound semiconductor.  For example, a hole with straight sides can be made in the compound semiconductor by use of a light spot and parallel (collimated) light rays.  An advantageous application of this process is the fabrication of a photodiode with a hole in the center for use in bidirectional communication systems and to monitor power output for optical communication sources.  The advantage of this process is that no damage occurs outside etched hole so that a maximum area of the photodiode remains active for detecting incoming radiation.  Another advantage of the process is that etching will stop where the material becomes p-type so that etching can be made to stop automatically at a p/n junction.

Abstract: ABSTRACT OF THE DISCLOSURE:          The process described herein comprises the crosslinking by radiation of a miscible mixture of two or more homopolymers such as A and B, etc., to give a block copolymer having one or more blocks of A and one or more blocks of B.  This process has the advantage of effecting crosslinking between blocks at such a rapid rate that substantial crosslinking is effected before phase separation occurs.  Moreover, the process may be modified by agents which promote crosslinking and also by compatibilizing agents to give improved miscibility of the A and B homopolymers.  Other modifications of the process effect improvements either by centrifugal separation of gelled high molecular weight products or by breaking down the molecular weights of such gelled portion either by mechanical shear or by ultrasonic treatment.  The product of this invention has a variety of uses  such as  in adhesive and coating compositions, molding compositions, compatibilizing agents, etc.
