IPC: H01S3/225
Filed: 1991-04-16
Abstract: ABSTRACT     The present invention relates to a technique which is effectively applied to the control of an oscillation wavelength and an oscillation output in a laser device.  The object of the invention is to adjust an angle of inclination of a wavelength selection element such as an etalon with high accuracy to always stabilize a laser output wavelength from a laser resonator.       The present invention provides a laser device having at least first and second wavelength selection elements arranged in series on a light path, at least one angle of inclination being adjusted to form a laser light from a laser medium into a narrower band, said laser device comprising an automatic micrometer head for finely adjusting said angle of inclination.       By using an automatic micrometer head capable of finely controlling a moving amount, fine adjustment of an angle of inclination with respect to a light path of a wavelength selection element can be made.  Therefore, it is possible to always stabilize a wavelength of a laser light released from a laser resonator.       Accordingly, the present invention can be effectively utilized for uses such as a light source in a lithography step in the manufacture of a semiconductor.

Abstract: The invention concerns a method for regulation of the transverse profile of the coating quantity on a paper or any other web material in a coating station, in which the web is passed over a backup roll and a coating agent is smoothed by means of a coating blade loaded against the web. The quantity of coating agent applied onto the web is regulated by actuators acting upon the constructions of the coating station. In the method; the transverse profile of the coating quantity applied onto the web is measured constantly, and a differential profile of the measured transverse profile and the desired transverse profile is calculated. The differential profile is fed as a regulation quantity to the actuators that adjust the transverse profile of the coating quantity so as to correct the transverse profile. The invention is advantageously carried out so that, in the method, an equation is approximated by means of calculation which corresponds to the transverse differential profile of the web coating quantity between the measured transverse profile and the desired transverse profile, and out of said equation, the average error and/or inclination and/or curvature of the differential profile and/or the frequency of a cyclic error of coating quantity is/are determined, they parameters corresponding to said values being fed as regulation quantities to regulation devices that regulate the properties of coating quantity so as to correct the transverse profile. The invention further concerns a coating station construction intended for carrying out the method.

Title: Fluorocarbon emulsions containing amino acid based anti-inflammatory agents and buffer systems
Inventor: LONG DAVID M JR
IPC: A61K31/02
Filed: 1990-09-26
Abstract: Disclosed are fluorocarbon emulsions comprising amino acids and substances related to amino acids, such as substituted amino acids or amphoteric groups of amino acid side chains, for example, the imidazolyl group of histidine. Emulsion formulations comprising imidazole and imidazole based drugs possess anti-inflammatory and anti-pyretic properties which counteract transient inflammatory responses which occur when these emulsions are administered in vivo. Lipid constituents of histidine-containing emulsions are protected against oxidation caused by free radical formation.  Disclosed also are emulsion formulations buffered with amino acids comprising histidine, imidazole, and related compounds that have a buffering capacity sufficient to maintain the emulsion pH within a specified range under storage conditions and protect these emulsions from the endogenous production of acid. Disclosed also is a method of calculation which assists in the selection of an optimum buffer composition and concentration to preserve physiological compatibility and stability of the emulsions within selected pH  limits.

Title: Pellet carrier fed pellet implanter apparatus
Inventor: STEWART R GLEN
IPC: A61D7/00
Filed: 1992-06-04
Abstract: ABSTRACT OF THE DISCLOSURE          An improved automatic pellet carrier (100) fed pellet implanting gun apparatus (10) is described.  The carrier is mounted in an opening (12b) through a front side (12c) of a retractable head (121 which is linearly moveable in a nose end (11c) of a handle assembly (11) along a longitudinal axis a-a.  The carrier relies upon an internal spring (107) to automatically register a pellet (101) in a bore (12a) in the retractable head so that by actuating a trigger (14), a drive rod (23) which travels linearly along the axis a-a and through the bore in the retractable head and through the carrier, can move the pellet into the barrel (13a) of a needle (13) that has been inserted into an animal or the like.  After the pellet enters the needle, the needle, the retractable head and the carrier are mechanically retracted into the gun with the carrier retracting along a slot (11f) in the nose so that the pellet is deposited in the animal, unobstructed by the needle.  Releasing the trigger causes the retractable head, the needle and the carrier to return to their rest positions in the nose of the gun and the drive rod to move out of the bore in the retractable head and into the handle assembly so that the internal spring in the carrier can automatically register the next pellet in the carrier into the bore in the retractable head of the gun apparatus.

Title: Convertible asphalt and soil remediation plant and methods of operation
Inventor: BRASHEARS DAVID F
IPC: B09B3/00
Filed: 1992-11-04
Abstract: CONVERTIBLE ASPHALT AND SOIL REMEDIATION PLANT AND METHODS OF OPERATION                     ABSTRACT OF THE DISCLOSURE      A materials-handling plant is convertible for producing asphalt by either batch or continuous drum mix processes or remediating soil.  Common to each process is a rotary drum and burner system for heating the materials, a primary separator and a baghouse for separating particulate matter from exhaust gas streams.  For asphalt production by a batch process, aggregate is dried in the drying section of the drum and discharged for combination with asphalt in a batch tower.  In the continuous drum mixer mode of asphalt production, dried aggregate is discharged into a drum mixing section for mixing with asphalt and recycle asphalt and conveyed to a storage silo.  In both cases, particulate dust is separated from the exhaust gas stream and combined with the resulting asphalt product.  For soil remediation, the contaminants in the soil are volatilized in the drum by contact with the hot gases of combustion.  Dust particles in the exhaust gas stream are separated and contaminants thereon volatilized in the baghouse.  The contaminant-free particles are recombined with the remediated soil in a mixer/cooler.  The resulting exhaust gas stream is subjecyed to elevated heat to volatilize any residualcontaminants.

Abstract: An environmentally innocuous effective replacement for thiourea is disclosed for use as a complexing agent in displacement plating processes in which the plating solution is applied to the substrate surface to be plated  by immersion or by spraying, cascading, pouring and the like. The replacement complexing agent is an unsymmetrical dialkylimidazole-2-thione compound having the formula:                            (see fig. I) wherein A is methyl or ethyl, and when A is methyl, B is a C3 to C6 alkyl or cycloalkyl group, and when A is ethyl, B is a C4 to C6 alkyl or cycloalkyl group.  Of this class of compounds, 1-methyl-3-propyl-2-thiocarbonyl-2,3-dihydroimidazole is preferred for immersion tin plating. This class of complexing agents is particularly useful in spray displacement tin plating for the manufacture of printed circuit boards wherein free tin metal is added to the plating solution.
