Abstract: ELECTROMAGNETIC SHIELDING PANEL     ABSTRACT OF THE DISCLOSURE      An electromagnetic shielding panel incorporates at least two electroconductive coatings.  In two of the panels the coatings are carried on separate sheets of float glass one of the coatings being an anti-abrasive coating is on the outermost surface of the glass in the panel arrangement while the other coating being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass in the panel arrangements.  In other panel arrangements the two coatings are located on opposing sides of one glass sheet and in two of the panels a plain sheet of float glass is employed to protect the soft silver coating.  In another panel a sheet of glass carrying an anti-abrasive coating is employed.  The panels are of the double glazed and the laminated type.  This invention utilises the enhanced capacitive coupling between the two coatings to effectively earth the innermost silver coating by way of the anti-abrasive coating without any direct electrical connection being required to be made to the innermost coating.

Abstract: ABSTRACT   An algorithm for rotating an image 90 degrees starts with an array or r rows and c columns of pixels. Each column of the pixel array is partitioned intowords of w pixels each, and the rows, the columns, the words in each column, andthe pixels in each word of the pixel array are all numbered starting at zero. Let v = rr/w1, where rr/w1 is the smallest integer greater than or equal to r/w. Similarly, let h = rc/wl.   The algorithm stores words of the original pixel array into a linear word organized memory as follows: it circular right-shifts each word i of column j by(j)mod w pixel positions and then writes in parallel this modified word into word address vj + i of the memory.   The algorithm fetches words of the stored pixel array from this memory rotating this pixel array 90 degrees as follows: it reads a whole word in parallel such that each pixel p of this word comes from pixel p of word address wvi +v((p + j +1)mod w) + ?(wv-j-1/w)? and then circular right-shifts this word by (j + 1)mod w pixel positions, thereby delivering word i of column j of a 90 degree rotated version of the original pixel array.

Abstract: METHOD AND APPARATUS FOR SUPPLYING COMPRESSED AIR TO AUXILIARY SYSTEMS OF A VEHICLE          Abstract of the Disclosure An apparatus for supplying compressed air to the auxiliary system of a vehicle such as an aircraft, or  other  device  powered  by  a  gas  turbine  engine, comprises an auxiliary compressor which is connected by a differential  to the main drive  shaft  of the compressor of the gas turbine engine.  A controller receives a signal from a pressure sensor at the output of the auxiliary compressor representing the pressure and/or flow rate of the compressed air discharged from the auxiliary compressor and compares that signal with a signal from the auxiliary system representing its requirements for compressed air which can be set at predetermined levels or dynamically determined during operation of the vehicle.  The controller is effective to control a variable speed motor connected to the differential which speeds up or slows down the auxil-iary compressor and thus varies the compressed air output from the auxiliary compressor to the auxiliary system of the vehicle.

Filed: 1991-05-16
Abstract: A universal safety adapter which is usable with different types of needles and syringes has integral first and second sections and a housing flexibly connected to one of the sections. In the case of the first section being adaptable to be mated with the hub of a needle assembly, the housing is flexibly connected thereto by way of a living hinge. The needle assembly is threadedly mated with an internally threaded annular collar surrounding a protrusion which is to be coupled to the hub of the needle assembly. The second section of the safety adapter, in a first embodiment, includes a female luer that is adaptable to be mated with different types of syringes, such as a luer slip syringe or a luer lock syringe. Once the needle assembly has been threadedly mated to the first section of the safety adapter, to ensure that the cannula of the needle assembly is not exposed so as to preclude accidental pricking by the needle, the housing is pivoted to a position whereby it completely envelops the cannula. At least one integral retainer mechanism in the housing prevents relative movement between the cannula and the housing once the housing has been pivoted to envelop the cannula. The dead space volume at the junction where the needle is connected to the syringe can be substantially reduced by a second embodiment of the safety adapter of the present invention which includes a male extension within the female luer.

Abstract: PR?CIS Dans l'utilisation d'un télescope sur une arche, on a remarqué que la monture qui soutient le télescope est fixée à la courbe de l'arche. L'oeil de l'archer est donc éloigné du télescope. Dans la présente invention, le télescope est disposé sur une branche principale qui est a justée à une structure fixe; celle-ci étant fixée à la courbe de l'arche. Cette branche principale permet de rapprocher le télescope très près de l'oeil de l'archer, ce qui est indispensable à une meilleure précision pour atteindre l'objectif visé. Le fait de regarder télescope de si près a pour avantage d'augmenter le champ de vision de l'archer, ce qui favorise automatiquement un degré de précision plus élevé. Il est à noter que l'arbre de vision peut se fixer aussi bien sur une arche gauchère que droitière.
