Abstract: SELF-HEALING ELECTRODE FOR UNIFORM NEGATIVE CORONA               Abstract of the Disclosure The present invention relates to electrodes used for charging electrophotographic image surfaces in copying machines.  More particularly, the disclosure is directed to the negative corona discharge electrodes which produce a negative charge that is applied to the photoconductive surface exposed to the corona discharge.  In the present invention, the electrode structure includes a combination of a wire of valve metal with a high resistivity coating spread uniformly over the surface of the wire.  The valve metal, one example being tantalum, may serve as the electrode wire itself or may surround an inner wire such as stainless steel.  By providing an electrode for corona discharge having a uniform high resistive coating, the plasma glow produced will spread uniformly along the length of the wire.          By using a valve metal, which form a hard oxide under the high resistivity coating, the electrode is self-healing in that if cracks or imperfections occur in the coating, the exposed valve metal will oxidize and fill in the cracks and imperfections.

Abstract: ABSTRACT           A converter yoke and stringing block assembly adapted to be threaded with a helicopter-dispensed conductor hauling line dropped thereonto from either side of a power line.  The yoke sub-assembly can be used in lieu of a conventional stringing block yoke thereby to convert a manually threaded block for threading by helicopter, or the features of the invention can be embodied in a stringing block as initially manufactured.  The separate yoke brackets are spaced apart to provide an open-ended threading passage and the exit end of the latter is initially extended by dislodgeable guide members shiftable to their normal retracted positions automatically as the advance end of the com-ductor running board enters the stringing block, the guide members being thereafter restrained in their normal retracted position until manually reset.  A load transfer latch normally interconnects the two brackets of the yoke and includes means for holding the latch open until dislodged by the conductor hauling line as it is threaded through the stringing block.

Abstract: Abstract of the Disclosure Ammonia, hydrogen cyanide and hydrogen sulfide contained in gas streams are separated from the gas streams by contacting the gas stream with an aqueous solution containing free oxygen for a time sufficient for the ammonia, hydrogen sulfide and hydrogen cyanide to react with the oxygen present to form ammonium thiocyanate and water for further treatment or disposal.      The preferred disposal method involves combining the aqueous solution with products obtained by the combustion of a fuel in the presence of oxygen in proportions to totally vaporize the constituents of the waste aqueous solution and form a resultant gas stream at a temperature of 700°F or more. The gas stream is then passed over a catalyst capable of hydrolyzing hydrogen cyanide to ammonia and/or nitrogen and hydrogenating any sulfur and sulfur dioxide present to hydrogen sulfide.  The ammonia which is formed is then separated from the gas stream by conventional means, followed by separation, when present, of hydrogen sulfide.

Abstract: PRODUCTION OF ALGAL BIO-POLYMERS            ABSTRACT OF THE DISCLOSURE      Cultivation of algae to produce long chain polymers having flocculating properties is disclosed.  Algae are cul-tivated in an aqueous nutrient medium until optimum culture densities are achieved and thereafter under conditions in which they become deficient in nitrogen thereby causing the cells to shift from a growth phase in which protein production predominates to a growth phase in which extracellular polymer production pre-dominates.  An adequate supply of other nutrients as well as CO2 and light are maintained in the culture medium during the latter phase to insure that a growth limitation is caused solely by a deficiency in nitrogen.  The algae produce high molecular weight polymers exhibiting strong flocculating activity.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a container for carbonated beverages, the container being generally of inverted frusto-conical shape and which is nestable with other similar containers.          It is circular in cross-section over the majority of its height from a top peripheral flange to a base portion.  The base portion is designed basically by hemispherical shell on which are formed foot portions on which the container can stand.  When a carbon-ated beverage is sealed in the container, the gas in the carbonated beverage will cause the internal pressure in the container to increase with the passage of time, so that the plastics material of the container will "creep".  As creeping takes place, the central region of the base portion moves downwards, said downward movement being resisted by strap portions.  The downward movement of the central region of the base portion increases the volume of the container and thereby decreases the pressure in the container.  The strap portions restrict the downward movement of the central region of the base portion and thereby restrict the deformation of the foot portions of the container.  Excess deformation of the foot portions is undesirable as it will cause a container to be unstable.  The volumetric increase of the container obtained by the deformation of the foot portions will tend to prevent bursting of the container due to pressure increased therein.

Abstract: ABSTRACT OF THE DISCLOSURE:     A rack frame for supporting-or withdrawing-rollers in continuous casting plant, comprising at least two rollers which are consecutive in the direction of travel of the continuous casting and connected to a common tiltable yoke on at least one side of the casting, the yoke being movable by piston-and-cylinder units in ways normal to the guided surface of the casting.  The yoke which is formed with abutment surfa-ces can be pulled by the piston-and-cylinder units against bea-ring faces associated with each roller on a fixed frame, there-by to limit the setting of the rollers to the casting.  In the present invention the accuracy of the frame remains unchanged for longer periods of duty, the life of the rollers is substan-tially lengthened and the quality of the casting with respect to surface and internal flaws and to the precision of the thick-ness of the casting is improved.

Abstract: METHODS OF PROVIDING CONTACT BETWEEN TWO MEMBERS NORMALLY SEPARABLE BY AN INTERVENING MEMBER          Abstract of the Disclosure A continuous length, flexible, polymeric substrate has thin layers of copper clad to opposite sides thereof.          Patterns of dry photopolymer material are applied to and mask selected portions of the copper to leave exposed other selected portions of the copper.  The copper clad substrate is guided by a series of cathodic electrode rollers exterior of a copper plating bath into successive passes through the bath.  Portions of the exposed copper contact the electrode rollers and couple the cathodic potential thereof to the bath to effect the plating of copper from the bath onto the exposed selected portions of the copper. Prior to initial engagement with the cathodic rollers, a series of protrusions are formed in portions of the exposed copper at a height relative to the thickness of the photoresist material sufficient to insure that the copper, by virtue of the protrusions, contacts the electrode rollers to facilitate the plating operation notwithstanding the intervening photoresist material.
