Abstract: Apparatus to protect glazed window or door panels against cold manifestation effective migration via glazing panel edge defined gaps, there being spaced apart outer, intermediate and inner glazing panels, the apparatus comprising holder structure projecting longitudinally endwise radially inwardly in said gaps, the holder structure being laterally sidewardly elongated, first synthetic resinous material retained by the holder structure to face laterally in a gap toward opposed intermediate panel edges, the material adjustably located at a position relative to the opposed intermediate panel edges characterized in that cold manifestation migrating through the gap via said material is confined to migrate in the spacing between the outer and intermediate panels, at opposite sides of the gap.

Abstract: In paper feeder apparatus, the combination comprising first means including a support for a paper stack and transfer elements for successively transferring paper sheets from the top of the stack upwardly and laterally to a delivered position, and optical control means to determine the level of an upper paper or papers in the stack to control the vertical positioning of papers on the stack, to enable said upwardly and laterally sheet delivering as the stack height diminishes, and a controller for cyclically controlling said transfer elements to integrate cyclic upward and lateral movement of successive sheets transferring from the stack.

Abstract: A valving assembly, comprises elongated tubular body, a first annular diaphragm in the body, and a first annular seat in the body engaged by the first diaphragm when pressurized fluid flow passes through the body and through the first diaphragm to deflect the first diaphragm, a second annular diaphragm in the body, and a second annular seat in the body engaged by the second diaphragm when said pressurized flow passes through the body and second diaphragm to deflect the second diaphragm, a third seat in the body engaged by the first diaphragm to block reverse flow through the body, an escape port in the body to allow escape of the reverse flow, and a drain port in the body to allow drainage of such fluid in the body upstream of the first diaphragm during such reverse flow.

Abstract: Jet engine inlet structure of a supersonic aircraft comprising the structure having an inlet ramp and an cowl lip spaced outwardly of the ramp so that entering air flows between the ramp and lip, the lip and ramp configured to produce a first oblique shock that extends outwardly from a forward portion of the ramp to pass ahead of the lip, and a terminal shock that extends outwardly from a rearward portion of the ramp to one of the following xo) a region just ahead of the lip xl) substantially to said lip. A non-uniform shock system is created that generates a central region of nearly isentropic compression and relatively ram recovery and an outer region of reduced ram recovery but entailing reduced cowl angle and drag. Translating cowl structure and also nozzle integration with the fuselage contour to reduce boat tail drag are also provided.
