Biologically 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 System
A 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.
Current 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 System
A 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.

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.

Quasi-optical polarization duplexed balanced mixer
(United States Patent and Trademark Office, 1985-04-02) Tatsuo Itoh; Karl D. Stephan; Board of Regents, The University of Texas System
An integrated planar antenna-mixer device for microwave reception utilizes a slot-ring antenna and a diode quad connected thereto. The device comprises a planar metallic sheet backed on one side by a dielectric layer. A circular ring pattern is cut from the metallic sheet forming a slot ring antenna with a central disc and a surrounding ground plane. Diodes of a diode quad are connected between the central disc and the ground plane with adjacent diodes being separated by 90.degree.. The incoming microwave signal is directed perpendicular to the device plane and polarized in a direction orthogonal to a local oscillator signal similarly directed. Operation is quasi-optical without waveguides.

Microencapsulation process
(United States Patent and Trademark Office, 1985-05-21) George W. Cuff; James W. McGinity; Board of Regents, The University of Texas System
Nylon coated microcapsules containing hydrophilic solvent-soluble anionic, cationic or quaternary drug salts were prepared by interfacial polycondensation techniques. In a first stage, the drug substance to be encapsulated is dissolved in an aqueous phase. Examples of drugs encapsulated are morphine sulfate, diphenhydramine hydrochloride, and methantheline bromide. Next the aqueous drug solution is dispersed in an organic phase. In a second stage complementary polycondensation reactants each in an organic phase are added separately, either sequentially or simultaneously, to the dispersion prepared in the first stage. Microcapsules of nylon form around the hydrophilic solvent soluble core drug substance.
