Abstract: Disclosed is a method for applying a yellow incandescent bugfoiler pigment coating comprising a fine-ground blend of praseodymium doped zirconium silicate and silica. This cadmium-free blend is preferably applied electrostatically in three coats to the interior of a bulb to diffuse the light and block the emitted UV wavelengths. The color of the blend will intensify with increasing heat and return to it's initial yellow color upon cooling.

Abstract: The effluent from mercury collected during the photochemical separation of the .sup.196 Hg isotope is often contaminated with particulate mercurous chloride, Hg.sub.2 Cl.sub.2. The use of mechanical filtering via thin glass tubes, ultrasonic rinsing with acetone (dimethyl ketone) and a specially designed cold trap have been found effective in removing the particulate (i.e., solid) Hg.sub.2 Cl.sub.2 contaminant. The present invention is particularly directed to such filtering.

Abstract: The present invention is directed to an improved photochemical reactor useful for the isotopic enrichment of a predetermined isotope of mercury, especially, .sup.196 Hg. Specifically, two axi-symmetrical flow reactors were constructed according to the teachings of the present invention. These reactors improve the mixing of the reactants during the photochemical enrichment process, affording higher yields of the desired .sup.196 Hg product. Measurements of the variation of yield (Y) and enrichment factor (E) along the flow axis of these reactors indicates very substantial improvement in process uniformity compared to previously used photochemical reactor systems. In one preferred embodiment of the present invention, the photoreactor system was built such that the reactor chamber was removable from the system without disturbing the location of either the photochemical lamp or the filter employed therewith.

Abstract: Disclosed herein is a wear-resistance alloy consisting essentially of about 10 to 40 wt % of Zn, about 3 to 10 wt % of Al, about 0.1 to 4 wt % of Cr, and optionally not more than about 8 wt % of Mn and not more than about 2 wt % of Ni, with the balance, Cu.
Abstract: The present invention is directed to several multisubstrate adduct inhibitors of glycinamide ribonucleotide transformylase (GAR TFase; E.C. 2.1.2.2), a folate-requiring enzyme of de novo purine biosynthesis. The compounds of the present invention will be useful to provide anti-gout and/or anti-neoplastic therapeutic agents or will serve as potentiators for other such agents. The most prefeffed, potent tight-binding multisubstrate adduct inhibitor of glycinamide ribonucleotide transformylase, is N.sup.10 -[5'-phosphoribosyl-1'-.beta.

Abstract: A photosensitive member for electrophotography having a photosensitive layer containing a hydrazone compound represented by the following general formula [I]: ##STR1## wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom; R.sup.3 represents a halogen atom; m is 1 or 2; and n is 0, 1 or 2. The photosensitive member has not only extremely high sensitivity but also sufficiently low residual potential. It is also highly resistant to fatigue so that the repeated use provides it with little accumulation of residual potential and little variation of surface potential and sensitivity.
Abstract: The present invention is directed to a method of electrolytically extracting liquid mercury from HgO or Hg.sub.2 Cl.sub.2. Additionally there are disclosed two related techniques associated with the present invention, namely (1) a technique for selectively removing product from different regions of a long photochemical reactor (photoreactor) and (2) a method of accurately measuring the total quantity of mercury formed as either HgO or Hg.sub.2 Cl.sub.2.
Abstract: A method for increasing the mercury flow rate to a photochemical mercury enrichment utilizing an entrainment system comprises the steps of passing a carrier gas over a pool of mercury maintained at a first temperature T1, wherein the carrier gas entrains mercury vapor; passing said mercury vapor entrained carrier gas to a second temperature zone T2 having temperature less than T1 to condense said entrained mercury vapor, thereby producing a saturated Hg condition in the carrier gas; and passing said saturated Hg carrier gas to said photochemical enrichment reactor.
