Title: Method of purifying beta-1,3-glucans
Inventor: HAZE AKIRA
IPC: A23L29/269
Filed: 1992-05-22
Abstract: Abstract of the Disclosure This invention relates to a method of purifying .beta.-1,3-glucans which comprises cooling a hot alkaline solution of a microbially produced .beta.-1,3-glucan in a mixture of water and a hydrophilic organic solvent, then, where necessary, further adding a hydrophilic organic solvent, and neutralizing the mixture containing precipitated glucan.    The invention provides a method of purifying .beta.-1,3-glucans which is commercially very advantageous in that it does not entail an excessive rise of viscosity and, hence, insures the ease of handling.  The .beta.-1,3-glucans purified by the method of the invention impart excellent thickening, water-holding, swelling and/or plastic characteristics to various substrates and can be used advantageously in chemical, food and other industries.

Abstract: Cette tourelle pour engins miniers comprend une poutre qui sert de guide à un chariot portant une perforatrice et à un chariot portant une unité de boulonnage, la poutre étant montée pivotante sur un support monté à l'extrémité d'un bras-support. Un magasin de boulons est aussi monté sur le support, et des moyens sont prévus pour le transfert successif des boulons entre le magasin et l'unité de boulonnage. Ces moyens font décrire, au boulon prélevé dans le magasin, un mouvement perpendiculaire à l'axe du trou foré, suivi d'un déplacement parallèle à cet axe. Le boulon est ainsi introduit partiellement dans le trou, avant d'être repris par l'unité de boulonnage pour son introduction complète. Des boulons de plus grande longueur peuvent ainsi être posés.

Title: Mobile communication system wherein a base station tranfers to another an identifier for a cell of call origination
Inventor: KITO EIJI
IPC: H04W8/08
Filed: 1992-06-11
Abstract: ABSTRACT OF THE DISCLOSURE:     When a mobile unit (21(p)) initiates a call for communica-tion in a first cell of a first cell set identified in an overall service area of base stations or cell sites by a first area identifi-er and moves into a second cell of a second cell set identified by a second area identifier, the first area identifier is transferred (S3(nl)) from a first station (17(nl)) corresponding to the first cell to a second station (17(n2)) corresponding to the second cell.  When the unit terminates the communication while present in the second cell, the second area identifier is transmitted (S3(n2)) to a central office (11) and to the unit if judged (S2(n2)) different from the first area identifier.  Each station therefore comprises a transferring and a transmitting arrangement.  Preferably, a channel disconnection signal (43) carries such a second area identifier.  The communication can be terminated at a counterpart unit.

Title: Image recognition system
Inventor: WALCH MARK A
IPC: G06V30/10
Filed: 1992-06-18
Abstract: ABSTRACT           An image recognition system includes a method and apparatus in which images are characterized and compared on the basis of internal structure, which is independent of image size and image orientation.  A library of reference images is first generated and stored, then each input image, or test image, is compared to the images stored in the library until a match is found.  The image is represented in memory as nodes, lines, and curves.  A plurality of descriptors, called reference keys and reference series, are generated for both the reference images and the test image.  The reference library is screened for likely matches by comparing the descriptors for the test image to the descriptors in the reference images in the library.  Inclusionary and exclusionary tests are performed.  After screening, the each of candidate reference images is searched by comparing the pathway thorough the reference image and the pathway through the test image, and by the degree of correlation between the reference and test images.  In addition, the link ratio, a measure of the portion of the test image actually matched to the reference image is computed.  Searching criteria, like the screening criteria are based on internal image structure, so that the the recognition process is independent of image size and image orientation.

Title: Process for elimination of low concentrations of hydrogen sulfide in gas mixtures by catalytic oxidation
Inventor: TOLLEFSON ERIC L
IPC: B01D53/86
Filed: 1992-09-23
Abstract: A process is described for the elimination of hydrogen sulfide from gas mixtures by catalytic oxidation over activated carbon catalyst which converts the hydrogen sulfide to elemental sulfur and water, the former being sorbed by the activated carbon while the latter is transported with the gas mixture and may be removed by known dehydration processes. The above oxidation process is conducted at elevated temperatures and pressures and with sufficient residence time to assure virtually complete conversion of the hydrogen sulfide with minimal production of by-product sulfur dioxide. Traces of heavy hydrocarbons in the feed gas mixture which may reduce the life of the catalyst and the quality of the sulfur product may be removed by cryogenic means or by sorption on an activated carbon guard bed. Both the activated carbon catalyst used to oxidize the hydrogen sulfide and the activated carbon used to remove heavy hydrocarbons from the feed gas may be regenerated by passing inert gas or product gas through the beds of these materials at elevated temperatures for sufficient time to remove the sorbed sulfur or the heavy hydrocarbons, respectively for use as by-products of the process.

Title: Contamination-resistant dispensing and metering device
Inventor: MATKOVICH VLADO I
IPC: B65D47/18
Filed: 1990-11-30
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to the field of liquid dispensing and metering devices that dispense a solution in drop form and protects the solution from contamination. In applications where contamination and proper dosage is a concern, the prior art discloses dispensers related both to the use of anti-bacterial agents added to the solution to prevent contamination and the use of a single dose device.  Both present problems, as the addition of the agent causes allergic reactions in some users, while the single dose device is inconvenient to the frequent user.  Prior art dispensers also do not permit control of metering for proper dosage.  This invention  solves these problems by providing a filter in the dropper portion of the device to prevent contamination of the solution.  The device includes a dropper having an outlet and filter.  The filter is a composite consisting of a liquophilic component and a liquophobic component.

Title: Cartridge tape system for helical scan transports
Inventor: LEONHARDT MICHAEL L
IPC: G11B15/665
Filed: 1991-10-23
Abstract: This system makes use of a tape cassette helical scan tape transport (415-421) and 3480-type magnetic tape cartridge (401) as the data storage media. The merging of these two incompatible elements is accomplished by the use of a novel interface that implements a "virtual tape cassette" using a tape cartridge (401) in a manner that makes this media compatible with the tape transport (415-421). The virtual tape cassette is implemented by providing a takeup reel (402) positioned with the magnetic tape cartridge (401) in a relationship that substantially matches the format of a magnetic tape cassette. A short tape threading arm (403) is used to retrieve the leader block (311) from the tape cartridge (401) and thread the magnetic tape (424) over a short tape threading path (423) to the takeup reel (402). Once the tape (424) is affixed to the takeup reel (402), the helical scan tape guide arms (415, 419) transport the length of tape (424) that is now exposed between the tape cartridge (401) and the takeup reel (402) to the rotary heads (416).
