Title: Wilson disease gene
Inventor: COX DIANE W
IPC: C12N9/14
Filed: 1993-09-21
Abstract: Wilson disease (hepatolenticular degeneration) is an autosomal recessive disorder of copper transport, resulting in copper accumulation and toxicity to the liver and brain.  The gene (locus WND) has been mapped to chromosome 13 band ql4.3.  On three overlapping yeast artificial chromosomes (YACs) from this region, a sequence similar to the proposed copper binding motifs of the putative ATPase (MNK) defective in Menkes disease was identified. It was shown that this sequence forms part of a P-type ATPase gene (Wc1) that is very similar to MNK, with at least six putative metal binding domains homologous to those found in prokaryotic heavy metal transporters.  This gene lies within a 300 kb region that has been identified as a likely location for WND.  The gene is expressed in the liver and kidney and is a candidate for Wilson disease.

Title: Process for refining used oils and conversion of acid-sludge produced therein to asphalt
Inventor: SANTOS BENJAMIN S
IPC: C10G27/00
Filed: 1994-02-21
Abstract: A process for significantly decreasing the acid sludge settling time in waste oil recovery processes comprising the steps of heating used oil to a high temperature above 725 degrees Fahrenheit, cooling the heated oil, adding an oxidizing agent to the oil, allowing the acid sludge to settle within a period of approximately 24 to 72 hours, separating the acid-sludge-free oil from the acid sludge which settles out of solution as a result of addition of the oxidizing agent, and adding a polishing agent and separating the re-refined oil from the spent polishing agent. The spent polishing agent is recycled, and the acid sludge which settles out after oxidation is converted to either hard, oxidized asphalt or soft asphalt or asphalt products such as emulsions etc. The process produces a high quality re-refined oil rapidly and economically with no acid sludge disposal problem.

Title: Power supply circuit for a gas discharge lamp
Inventor: NERONE LOUIS R
IPC: H05B41/282
Filed: 1994-03-24
Abstract: POWER SUPPLY CIRCUIT FOR A GAS DISCHARGE LAMP           ABSTRACT OF THE DISCLOSURE A power supply circuit for a gas discharge lamp is disclosed. The power supply circuit includes a circuit for providing a d.c. bus voltage on a bus conductor, and a resonant lamp circuit. The resonant lamp circuit includes a gas discharge lamp, a first resonant impedance in series with the gas discharge lamp, and a second resonant impedance substantially in parallel with the gas discharge lamp. The resonant load circuit operates at a resonant frequency determined by the values of the first and second resonant impedances. Further included is a series half-bridge converter for impressing across the resonant load circuit a bidirectional voltage, and thereby inducing a bidirectional current in the resonant load circuit. The converter comprises first and second switches that are serially connected between the bus conductor and a ground conductor, that have a common node coupled to a first end of the resonant load circuit and through which the bidirectional load current flows, and that have respective control terminals for controlling the conduction states of the switches. A circuit is provided for generating a feedback signal representing current in the second resonant impedance. Feedback circuitry, responsive to the feedback signal, provides respective control signals on the control terminals of the first and second switches. The feedback means controls the switching of the switches in such manner as to reduce a phase angle between the bidirectional voltage and the bidirectional current when the feedback signal increases, and vice-versa. Lamp power and lamp current are less subject to variation as the line voltage varies.

IPC: C01B32/336
Filed: 1994-01-20
Abstract: An improved process is provided for the manufacture of a catalytically-active carbonaceous char capable of rapidly decomposing hydrogen peroxide in aqueous solutions. The process of the invention uses a low temperature carbonization and extensive oxidation of a bituminous coal or bituminous coal-like material followed by exposure to a nitrogen-containing compound at high temperatures during the initial calcination and/or activation. The resultant catalytically-active chars have the ability to rapidly decompose aqueous solutions of hydrogen peroxide and are useful for catalytic conversion of H2S, SOx, NOx, chloramines, and/or peroxides in liquid and/or gaseous streams. The catalytic activity of the char can be measured by adding the char to an apparatus (10) comprising a Dewar container (11) positioned on a magnetic stirrer (12) including a stir bar (13), a cap (14), a funnel (15), a vent (16), an opening (17), a thermocouple (18), an ice point compensator (21) and a strip char recorder (22).
