    摘要: The present invention is a workpiece positioner comprising a spherical ball having an aperture, a upper spherical dome housing having a groove through the housing beginning at the apex of the dome and extending down the side of the housing to approximately 90 degrees from the apex. The ball is positioned within the housing. A spherical seat is positioned against the ball. At least one tension disc spring is positioned against the seat. A radial braking means is positioned against the spring. A flange ring is affixed to the base of the housing securing the ball, seat, at least one spring and braking means in place within the housing. A base is secured to the braking means. An actuator lever is connected to the seat through the base. A cam and handle assembly is connected to the lever and a rod is affixed within the aperture of the ball.

    摘要: An improved poly(vinyl acetate) which on hydrolysis and reacetylation has an intrinsic viscosity of at least about 5 dL/g and an improved poly(vinyl alcohol) which on acetylation yields poly(vinyl acetate) having an intrinsic viscosity of at least about 5 dL/g. Such poly(vinyl acetate) can be prepared by photo-initiated free radical bulk polymerization of vinyl acetate with controlled low initiator concentration, polymerization temperature and reaction time. Such poly(vinyl alcohol) can be prepared by conventional alcoholysis of the poly(vinyl acetate).

    摘要: Various technologies for mitigating distortion in coherent image products generated from SAR data are described herein. Synthetic aperture radar (SAR) datasets generated based upon SAR returns from first and second passes of a SAR platform over a scene are received. The SAR datasets can be co-notched at matching sample indices to improve coherence of SAR images generated from the datasets. Windowed SAR data is generated by applying independent windows to subsets of each of the datasets to reduce sidelobe levels of their image impulse responses. Coherent image products are generated based upon the windowed SAR data, wherein an image quality of the coherent image products is improved as compared to coherent image products generated based upon the SAR datasets.

    摘要: A split casing (10) of low, coefficient of expansion material, has internal upstream facing slots (12). A semicircular shroud ring (16), of high coefficient of expansion material, carries the vanes (18), and has a tongue (20) sliding within casing slot (12). Casing stop lugs (14) and shroud stop lugs (22) have mutually abuttable surfaces (70,72) to antirotate the shroud within the casing. The distance between abuttable surfaces of the casing is greater than the distance between abuttable surfaces of the shroud ring at room temperature, but the distance are the same at the long time operating temperature.
