Abstract: The invention relates to an analytical technique for the quantitative determination of an analyte and a reagent solution useful in said quantitative determination. The analytical technique is conveniently adapted for quantitative determination of carbonyl and even more particularly adapted for finishing an alcohol produced in the Oxo Process.

Abstract: An igniter for a combustor of a gas turbine engine includes a body section mounted on a ball joint within a standoff cylinder. The standoff cylinder, in turn, is mounted on the casing of the combustor. An electrode tip, extending from the body section if tightly fitted into a hole in the combustor liner. The ball joint permits substantial transverse motion of the electrode tip to fit it through the hole during installation of the igniter, and to track the position of the hole if it should move relative to the casing due to differential thermal expansion during operation of the combustor. Seals between mating parts prevents the leakage of air from the interior of the casing.

Abstract: A stereoscopic viewer using a prism to separate the two images and capable of producing a stereoscopic effect from one image due to refraction in the prism; in one embodiment a V shaped slide mount containing one transparency normally oriented and a second laterally reversed may be mounted in a housing causing a light switch to close, activating a bulb which illuminates a diffusing glass which lights the transparencies, the light passing through the transparencies to refract through the prism and converge on a front magnifying lens from which a viewer can see the image stereoscopically; a single slide may also be inserted in the viewer and a black flexible slide switch operated to cover one face of the prism and to light the bulb to show the image stereoscopically; movie films may be projected on screens and the images refracted through a prism and magnified through a magnifying lens to permit a viewer to see stereoscopic movies.

Abstract: A bite indicating fishing light clips on a fishing rod and has upper and lower hooks projecting from it substantially parallel to the rod through which the fishing line passes so that bite produced tension on the line pulls the hooks into contact lighting the light. A longitudinally sliding switch button flexes one hook toward the other to turn on the light and to set the light's sensitivity to line tension. The lower hook has a base extending through a casing to form a bulb holding clip at the end of the casing remote from the hooks and the upper hook extends into the casing to form a battery contact at the end of the casing disposed toward the hooks. The casing is formed in two longitudinal halves one of which is hinged to the other on a downward and longitudinally bent pin formed from the base of the lower hook.
