ItemPhotocatalytic methods for preparing metallized powders(United States Patent and Trademark Office, 1981-04-28) Allen J. Bard; Wendell W. Dunn; Bernhard Kraeutler; Board of Regents, The University of Texas SystemPhotocatalytic methods are disclosed for the preparation of metallized powders. Specifically, such methods include the photodeposition of platinum, copper and other metals on TiO.sub.2 powder and other semiconductor powders. The powders thus prepared are particularly useful as catalysts. ItemMethods of photocatalytic decarboxylation of saturated carboxylic acid(United States Patent and Trademark Office, 1981-12-01) Allen J. Bard; Bernhard Kraeutler; Board of Regents, The University of Texas SystemMethods for heterogeneous photocatalytic decarboxylation of saturated carboxylic acids on several n-type semiconductor powders are disclosed. Major reaction products are the corresponding alkanes and carbon dioxide. ItemAlcohol and aldehyde production using ruthenium carbonyl catalysts(United States Patent and Trademark Office, 1981-12-15) Rowland Pettit; The Board of Regents of the University of Texas SystemThe present invention is an isomerically specific improvement of the oxo process reaction. It comprises the reaction of an olefin with carbon monoxide and water or hydrogen in a basic solution in the presence of a ruthenium carbonyl catalyst to preferentially produce the next higher normal aldehyde, or alcohol. ItemHybrid double-absorption cooling system(United States Patent and Trademark Office, 1983-02-15) Howell, John R.; Peng, C.S. Patrick; Board of Regents, The University of Texas SystemA hybrid double absorption air cooling system employing a liquid desiccant solution and capable of operating at low heat source temperature between 55.degree. C. and 80.degree. C. is provided. In one embodiment the system which utilizes low-grade thermal energy, includes an open absorber employing a liquid desiccant solution for absorbing moisture from air passing therethrough, a cooling coil adapted for cooling air passing through the open absorber, and a vapor-absorption refrigeration system which employs the liquid desiccant solution as an evaporable refrigerant and is adapted for cooling and circulating a working fluid, such as water, through the cooling coil and for circulating the desiccant solution through the open absorber. In an alternate embodiment, an open evaporator is adapted for providing cooling water to the open absorber. ItemBiologically active thymones from the thymus(United States Patent and Trademark Office, 1983-02-22) Karl A. Folkers; Teresa M. Kubiak; Henryk M. Stepien; Naoki Sakura; Board of Regents, The University of Texas SystemA class of three substances has been isolated in highly purified form and in substantially pure form by utilizing thymus tissue as a source material. These three substances are designated thymone A, thymone B and thymone C. Thymones A and B are new peptides which yield approximately 13 and 14 individual amino acid moieties, respectively, on acid hydrolysis. Thymones A and B are chemically characterized by electrophoretic and chromatographic values which are appropriate for substances which are substantially pure. Thymone C was highly purified and its biological activity was reproducibly detected and measured. Thymones A, B and C stimulate the proliferation of lymphocytes. Thymone A stimulates the formation of cyclic adenosine monophosphate. Thymone B stimulates the formation of cyclic guanosine monophosphate. The biological activities of these thymones to stimulate the proliferation of lymphocytes and the formations of cyclic nucleotides are basic hormonal functions for the therapeutic enhancement of the immune system in patients who have immune deficiencies from diverse causes. ItemCurrent limiting device for overcurrent protection(United States Patent and Trademark Office, 1983-09-20) William F. Weldon; Herbert H. Woodson; Board of Regents, The University of Texas SystemA current limiting device for use with a circuit breaker in an electric power system utilizes mutual inductance variation between movable windings to limit current to safe levels. In the device, first and second coil windings are electrically connected for current flow therethrough and magnetically linked for mutual inductive coupling. The effective inductance of the connected coil windings is functionally related to the relative physical positioning of the coil windings. The coil windings are movable relative to one another, so as to provide for variation in the effective inductance of the two coils. Structure is provided for disposing the coils in an initial relative positioning, the structure being yieldable to a force produced between the coils due to a predetermined magnitude of current flow through the coils. The force produced between the coils acts to change the relative positioning of the coils, increasing the effective inductance, and thereby limiting the current therethrough. In an alternative arrangement, movement of the coils to designated positions of relative placement due to a predetermined magnitude of current flow therethrough may be utilized to open a set of electrical contacts or to trigger a conventional circuit breaker interrupting the circuit. ItemBrush actuator for homopolar generator(United States Patent and Trademark Office, 1984-07-10) William F. Weldon; John H. Gully; Kurth P. Bousman; Board of Regents, The University of Texas SystemA homopolar generator having a rotor with a slip ring surface utilizes an inflatable diaphragm to force the current-collecting brushes into contact with the rotor slip ring. The diaphragm is molded around a metal core. An opening in the metal core directs pressurized gas into a diaphragm cavity to expand the diaphragm against the back of the brush. ItemPeptide antagonists of substance P(United States Patent and Trademark Office, 1984-11-06) Karl A. Folkers; Xu Jie-Cheng; Board of Regents, The University of Texas SystemUndecapeptides retaining the amino acids in positions 2, 3, 4, 5, 6, 8 and 10 of substance P (Arg.sup.1 -Pro.sup.2 -Lys.sup.3 -Pro.sup.4 -Gln.sup.5 -Gln.sup.6 -Phe.sup.7 -Phe.sup.8 -Gly.sup.9 -Leu.sup.10 -Met.sup.11 -NH.sub.2), but having substitutions in positions 1, 7, 9 and 11 of substance P have been discovered to have high antagonistic activity to block substance P in biological systems. Exemplifying these potent antagonists is D-Arg.sup.1,D-Trp.sup.7,D-Trp.sup.9 -Leu.sup.11 -Substance P, which is an effective inhibitor and has high potency. These antagonists of substance P are useful to elucidate some biological mechanisms of substance P, and to treat inflammatory responses in the eye for medical practice in ophthalmology, and to be novel analgesic agents for medical applications. ItemDi- and triphenylated cation radical polymers and their use as Diels-Alder catalysts(United States Patent and Trademark Office, 1985-03-05) Nathan L. Bauld; Dennis J. Bellville; Board of Regents, The University of Texas SystemA regenerative catalyst composition is provided comprising polymer supported covalently bound di- or triphenylated cation radical salts, wherein the cation radical is a Group VA element and the complementing anion is a Lewis acid anion or other anion, such as perhalo acid or acid metal halide. The phenylated cation radical salts, either polymer supported or unsupported, are useful catalytic agents facilitating the versatile Diels-Alder organic synthetic reactions to form cyclohexene compounds including the more intricate terpenoids, steroids, alkaloids, and prostaglandinoids. ItemSynthetic pyridyl-alanyl decapeptides having antiovulatory activity(United States Patent and Trademark Office, 1985-03-12) Karl A. Folkers; Cyril Y. Bowers; Teresa M. Kubiak; Janusz Stepinski; Board of Regents, The University of Texas SystemPyridyl-alanyl decapeptides have been effectively synthesized and found to have antiovulatory activity. The exemplary [N-Ac-D-2-Nal.sup.1,pCl-D-Phe.sup.2, D-3-Pal.sup.3,D-Arg.sup.6,D-Ala.sup.10 ]-LHRH has very high potency to inhibit ovulation, both parenterally and orally. Also, this exemplary pyridyl-alanyl-decapeptide showed an unexpected prolonged duration of antiovulatory activity. Such pyridyl-alanyl-decapeptides are useful to control reproduction.
