The ability of human hair to be effectively colored by a bismuth containing dyeing system involves a complex interaction of a number of components in the dyeing system and requires the presence of an excess of sulfur ions in order to provide the necessary sulfur  for  the  formation  of  bismuth  sulfide  or trisulfide in the hair fibers.  The catalyst component described hereinbefore provides a convenient means  whereby the negative oxygen of the catalyst may attract the positive bismuth ion and the positive carbon of the catalyst may attract  the  negative sulfur ion.  After penetration of the hair fiber and subsequent exsiccation, the attracted ions will unite to form the colored bismuth sulfide or trisulfide component within the hair fiber.    This invention provides for a novel system for dyeing human hair  comprising  a  bismuth  salt  and  a catalyst component  in admixture with a composition comprising triethanolamine, at least one sulfur containing component, Triton X 100* , and water.     * a trade mark

Abstract: ABSTRACT        A process for the production of heavy oil from a subterranean oil reservoir by the injection of a hot aqueous fluid into the reservoir and the injection of a diluent solvent down the production well to produced a blend of solvent and oil having a decreased viscosity. The reservoir oil has a density greater than the density of water.  The diluent solvent has a density such that the density of the resulting blend recovered from the production well also has a density greater than the density of the water.  The water produced from the production well is separated from the blend and the blend then fractioned to recover a solvent fraction of the requisite density.  This solvent fraction is then returned to the production well to produced additional blend within the well in a continua-tion of the process.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided of forming a circular chuted mixer from an originally circular scalloped blank.  The method utilizes a common mechanical press with male and female die portions. The female portion is pressed down over the blank against the male portion to form a convolution in the blank, with progressively increasing height.  Successive convolutions are formed which tends to gather together the radially outer portion of the blank thereby straightening its originally circular shape. Repeating this process forms a relatively straight band having convolutions forming chutes therebetween. Individual chuted bands can be joined together to form a single circular chuted mixer.

Abstract: METHOD AND APPARATUS FOR ANALYSIS OF CORNEAL SHAPE                 Abstract of the Disclosure An analysis of the corneal shape through the com-bination of several keratometer measurements is disclosed. The eye is preferably scanned to a nasal angular position,  a central angular position and a temporal angular position. The central position is straight ahead along the patient's line of sight.  The temporal and nasal positions are in the broad range of up to 5 to 22°; the intermediate range of 10 to 15°; and the narrow range of 12 to 14° on either side. Measurements in sphere, cylinder and axes are taken.  Astig-matism is in the more preferable format of 0-90° astigmatism and 45-135° astigmatism.  When each individual point is measured with its respective estimate for sphere and cylinder components, these measurements are fitted to an idealized parameter.  Then the three sets of curvature measurements taken at the specified locations are reduced to a set of adjusted, idealized curvatures all fitted to an elliptical model.  Thereafter, these fitted values create final corneal shaped parameters, the particular process here including the creation of intermediate parameters.  Finally, readings of central "k", corneal shape, apex position, cap size, vault height, corrected central "k" and goodness of fit are all set forth.

Abstract: COLLAGEN ORIENTATION            Abstract Monomeric collagen is oriented in solution and the orientation is retained in the resulting gel by set-ting up convective flow paths in the solution during gelation. The convection is induced by uniform peripheral heating of the cold, collagen solution in a small-diameter cylinder. Oriented collagen produced in this manner has excellent wet strength for use in implants for natural reconstruction of body collagen.
