Abstract: TITLE            VACUUM SANDER            ABSTRACT OF THE DISCLOSURE          A vacuum sander including a porous abrasive sheet mounted on the front surface of a backing plate.  A manifold covers the rear surface of the backing plate, and the interior of the manifold communicates with the abrasive sheet through a plurality of bores in the backing plate.  The manifold is maintained at reduced pressure by a partial vacuum communicat-ing with the manifold through a tubular handle which is secured to a hollow sleeve projecting from the rear of the manifold.          The sleeve extends into the manifold through an aperture and is connected to the backing plate through a universal joint so that the handle can intersect the plate at virtually any angle.          An air-impervious boot fastened between the sleeve and the manifold prevents air from leaking into the manifold through the aperture.  The residue produced by using the sander is collected by the vacuum in the manifold and conveyed to the vacuum source through the tubular handle.

Abstract: DATA BUS ARRANGEMENT FOR JOSEPHSON          TUNNELING DEVICE LOGIC INTERCONNECTIONS     Abstract of the Disclosure This invention relates generally to data bus arrangements and is more specifically related to data bus arrangements for use with Josephson junction devices.  Still more specifically it relates to a star data bus interconnection arrangement whereby a plurality of ports are placed into two-way communication with each other without the generation of spurious, reflected signals.  Each of the Josephson devices which is controlled by outputs from a computer or other logic circuit arrangement on an associated control line is supplied from its own constant current source.  Each device is effectively placed in parallel with every other device by transmission lines of the same characteristic impedance connected at a node or nodes.  The transmission lines which are terminated by a resistance equal to the characteristic impedance of the transmission line absorb incoming signals and prevent the reflection of such signals back to the node or nodes.  The number of ports and transmission lines connected to a node is limited only by such practical considerations as the ability of a sensing junction to respond to the magnitude of the current pulse supplied to each transmission line after splitting at the node or nodes.  In common with other terminated line Josephson circuits, switching speed in the order of tens of picoseconds are obtainable.

Abstract: ABSTRACT           In an improved system for medical imaging employing a transducer for transmitting and detecting ultrasonic vibrations, a digital scan converter accepts echo signals detected by the transducer and transducer position signals identifying the point of origin of the signals in a scanning plane transversely oriented rela-tive to the body of the patient under study.  The ampli-tudes of the echoes detected are stored at memory loca-tions associated with the points of origin of the echoes.          Peak detection analysis is performed on large echoes emanating from higher impedance tissue interfaces within the scanning plane, while cumulation and normalization analysis is performed on small echoes emanating from low impedance tissue interfaces within the scanning plane.          Sensitivity to otherwise unobtainable image details, signal to noise ratio, and freedom from distortions is maximized, yet the improved system may be used both in the static and real time imaging modes.

Abstract: LIGHTING FIXTURES              ABSTRACT OF THE DISCLOSURE        In a lighting fixture, glare-free uniform illumination is achieved by means of a plurality of nested generally frusto-conical reflectors surrounding the light source of the fixture.  The reflectors are shaped and positioned relative to one another and to the light source to concentrate light in the range of 65 to 71 degrees from downward vertical and to cause the intensity of the light to progressively decrease as the angle from downward vertical decreases from 65 degrees toward zero.  The projected light from the fixture is concentrated in the 65 to 71 degree range from down-ward vertical in part by light radiated from the source at near horizontal and higher angles being doubly reflected between the frusto-conical reflectors and then projected in the high angle range.  The reflectors are positioned relative to one another, to the light source and to baffles, to cut off any light from being projected at an angle from downward vertical greater than 75 degrees.  The frusto-conical reflectors are mounted on three vertically extending rods surrounding the light source to provide an inexpensive reflector assembly construction.

Abstract: A B S T R A C T         The present invention resides in the area  of corrosion inhibition in gas conditioning solutions.         The invention is a composition for inhibiting corrosion of iron and steel by carbon dioxide in gas conditioning solutions, consisting of inhibiting concentra-tion of one part by weight of a quaternary pyridinium salt and 0.001-10 parts of a thio compound which is a water--soluble thiocyanate or an organic thioamide, and a small amount of cobalt as a water-soluble divalent cobalt compound.     The advantages obtained are that corrosion is decreased substantially compared with previous inhibitor systems, when substantial amounts of carbon dioxide are removed by the solution, and that the present inhibitor system is non-toxic in contrast to previous systems employing arsenic, antimony or vanadium.
