Abstract: Abstract of the Disclosure A rapid method for forming carbon structures from flexible poly-urethane resin strands, which faithfully reproduces the geometry of the uncarbonized polyurethane resin strands, by infusing the polyurethane resin strands with a curable furan resin or resin precursor is described. The furan resin as a curable liquid resin or resin precursor swells the polyurethane strands during infusion and forms a gel-like alloy structure with the polyurethane resin as the solid phase.  An important step in the method which assists in preventing cracking during carbonization and which is essential to faithful strand geometry reproduction is the substantial removal of the liquid resin or resin precursor coating from the poly-urethane strand surfaces after the infusion or swelling step.  The method allows rapid carbonization with less than about five hours heating of the infused structures without cracking.  The resulting carbon strands remain crack-free and strong even when exposed to rapid temperature variations. The carbonized strands are preferably in the form of vitreous or glassy carbon and are particularly useful for high temperature applications in the presence of neutral or reducing gas conditions or in a vacuum.

Abstract: METHOD AND MEANS FOR SUPPRESSING OZONE GENERATED BY     ARC LAMPS                    ABSTRACT OF THE DISCLOSURE    A method and means for suppressing ozone generated by high pressure xenon arc lamps and similar luminous discharge arc lamps of a type normally generating ozone. The ozone-generating lamp is enclosed in a gas-tight housing having a quartz or sapphire light emission window able to transmit light including ultraviolet. The housing has metal cover plates on its various sides acting as heat sinks, each of which has a large number of external heat-radiating fins. Clearance is provided inside the housing sufficient to cause the ozone formed by short wavelengths to be broken down by thermal contact with the lamp And to be thus converted into stable O2. The heat generated by the lamp in the housing is transferred to the walls of the housing and is dissipated by the external heat-rad-iating fins. The inner surfaces of the cover plates arc blackened to absorb waste light. The arc is oscillated by an alternating current magnet to continuously shift the area of thermionic emis-sion of electrons from the cathode so as to minimize local deter-ioration of the cathode and to prevent flicker. The technique oper-ates to selectively remove the short ozone-producing wavelengths (180 to 200 nm) from the radiation emitted through the emission window.

Tanner ABSTRACT OF DISCLOSURE              A therapeutic device for skin lesions is provi-ded in which adhesively coated flexible strips are stuck to skin on opposed sides of the lesion, aligned to prevent late-ral displacement of the skin and drawn together by flaps to close the skin over the lesion.  This device allows the lesion to heal without the formation of keloids.  The flaps may be pulled around the side bars of a buckle member to draw the flexible strips to close skin over the lesion, and then the flaps stuck to the flexible strips to hold the skin closing the lesion.  For surgical incisions a transparent, removable cover may be on the folded back flaps, and the surgical inci-sion made through the transparent, removable cover, markings on the strips may be used to align them, and the lesion may be closed by sticking the flaps together in face-to-face relation.

Abstract: ABSTRACT OF THE DISCLOSURE            The absorption of gas by a fluent material conducted through a gas transfer apparatus is enhanced by continuous pressurization while it is being recirculated alternately through two closed loops.  Flow chambers in each of said closed loops, within which the fluent material is gasified during each cycle are alternately switched out of the closed loops so that the gasified fluent material accumulated therein may be displaced by flow from the source under a lower pressure than that of the fluent material trapped in the closed loops.

Abstract: ABSTRACT:                Passband equalizer in a system for data transmission by means of phase modulation.  The equalizer comprises two filters in quadrature with adjustable coefficients.  Difference circuits connected to the equalizer output form difference signals between the two quadrature components of the equalizer output signal and the two components of an estimated signal which is especially formed from phase jumps associated with the transmitted data signal.  A pair of difference circuits is associated with each pair of corresponding coefficients of the two filters and forms difference available in the two filters in places corresponding with the said pair of coefficients.  The changes in the coefficients are calculated from the above said difference signals.                      -??-

Abstract: Abstract A new part length rod is provided which may be used to not only control xenon induced power oscillations but also to contribute to shutdown reactivity when a rapid shutdown of the reactor is required.          The part length rod consists of a control rod with three regions.          The lower control region is a longer weaker active portion separated from an upper stronger shorter poison section by an intermetiate section which is a relative non-absorber of neutrons.  The combination of the longer weaker control section with the upper high worth poison section permits the part length rod of this invention to be scrammed into the core.  When a reactor shutdown is required but also permits the control rod to be used as a tool to control power distribution in both the axial and radial directions during normal operation.
