Abstract: AXIAL FABRICATION OF OPTICAL FIBERS            Abstract of the Disclosure An improved technique for producing optical fibers is disclosed.  In this technique the optical fiber preform is fabricated by axial deposition from a direction along the preform axis as opposed to radial deposition from a direction perpendicular to the preform axis.  The instant technique does not require a cylindrical mandrel and, consequently, the technique does not require removal of a mandrel and the collapse of a non-solid preform prior to drawing.  In addition to these advantages, the technique may be used to form optical fibers with highly resolved longitudinal gradations in index of refraction.  The resolution of such gradations when formed using the instant technique is limited only by the deposition rate and the ability to rapidly alter the concentration of the material being deposited.

Abstract: ABSTRACT OF THE DISCLOSURE      A method is provided for producing solar cells employ-ing slightly curved or nearly flat monocrystalline silicon ribbons.  The ribbons are formed by cutting or slicing monocrystalline hollow tubes along their lengths.  The tubes may be provided initially by growing the latter from the melt according to the EFG Process.  As is well known in the art, in the EFG Process, monocrystalline hollow tubes may be grown from a thin film of melt which is supported on the upper end surface of a suitably shaped die member that has one or more capillaries for feeding melt to its upper end surface from a reservoir pool so as to automatically replenish the film.

Abstract: ABSTRACT OF THE DISCLOSURE           A self-emulsifying anaerobic-curing composition is disclosed. The composition is rendered self-emulsifying by incorporating certain anionic and/or nonionic surfactants in a concentration range of about 0.25 to about 10.0 percent.  The preferred anionics comprise the petroleum sulfonates and the sodium alkyl or alkyl-aryl sulfonates.  The preferred nonionics comprise the ethoxylated alkyl alcohols, the ethoxylated alkyl phenols, and the polyoxy-ethylene/polyoxypropylene glycols.  Any anaerobic monomer or monomer mixture in which the surfactant is soluble and compatible with the cure system may be used.      These self-emulsifiable compositions have the advantage of being readily removed from surfaces by washing with water, which makes them especially useful in impregnation processes where uncured resin must be removed from areas which are difficult to wash, such as small, blind holes.

Abstract: A CIRCUIT FOR CORRECTING SETUP ERROR IN A        COLOR TELEVISION RECEIVER                 Abstract Of The Invention A horizontal deflection circuit of a color television receiver includes a horizontal output transformer with a secondary winding across which a voltage is developed and includes a horizontal deflection winding coupled to a pincushion correction winding of a pincushion reactor.  In response to the current flowing in the vertical deflection winding, the inductance of the pincushion correction winding varies in a manner providing for East-West pincushion distortion correction.  For setup, in the service mode of operation, the vertical deflection circuit is disabled.  A circuit, coupled to the pincushion reactor, adjusts the inductance of pincushion correction winding to compensate for a change in the inductance caused by disabling of the vertical deflection circuit for maintaining the voltage across the horizontal output transformer secondary winding substantially unchanged during setup.
