  • Patent number: 6962413
    Abstract: An auxiliary frame for detachably mounting in front of a spectacle frame includes a mounting frame and a retention arrangement. The mounting frame supports two shelter lenses for detachably mounting on a spectacle bridge. The retention arrangement includes two guiding members and two urging members. The two guiding members are rearwardly extended from two inner sides of the shelter lenses respectively and defined a guiding distance between the two guiding members which is smaller than the lens distance of the spectacle frame. The two urging members define an urging distance which is larger than the lens distance of the spectacle frame, such that when the guiding members are extended at the two inner sides of the spectacle lens respectively, the two urging members are adapted for applying an urging force against the two inner sides of the spectacle lens respectively.

  • Patent number: 6602700
    Abstract: Described herein are four phenolic acid esterases, three of which correspond to domains of previously unknown function within bacterial xylanases, from XynY and XynZ of Clostridium thermocellum and from a feruloyl esterase of Ruminococcus. The fourth specifically exemplified phenolic acid esterase is a protein encoded within the genome of Orpinomyces PC-2. The amino acids of these polypeptides and nucleotide sequences encoding them are provided. Recombinant host cells, expression vectors and methods for the recombinant production of phenolic acid esterases are also provided. Further provided are methods for improving nutrient availability and ferulic acid availability when food or feed, or other material is treated with a phenolic acid esterase, desirably in combination with a xylanase.

  • Patent number: 6146129
    Abstract: A cigarette lighter which has a safety locking device utilizing a spring biased latch. The cigarette lighter comprises a case, a top cover hingeably attached to an upper part of the case, a lighter seat, a press-down button, and the safety locking device. The latch is slidable mounted on top of the press-down button of the cigarette lighter. The latch is biased by an internal coil spring, which urges the latch to be engaged with the lighter seat, thereby preventing the press-down button from being pressed-down. When a user intends to use the cigarette lighter, the latch can be slid laterally against the spring force of the coil spring to disengage the latch from the lighter seat, thereby allowing the press-down button to be pressed down and ignite the cigarette lighter. Once the user releases the press-down button, it returns upwardly while the latch is biased back by the coil spring and automatically engages with the lighter seat again and thereby locks the press-down button.

  • Patent number: 6114158
    Abstract: A cDNA (1,520 bp), designated celF, consisting of an open reading frame (ORF) encoding a polypeptide (CelF) of 432 amino acids was isolated from a cDNA library of the anaerobic rumen fungus Orpinomyces PC-2 constructed in Escherichia coli. Analysis of the deduced amino acid sequence showed that starting from the N-terminus, CelF consists of a signal peptide, a cellulose binding domain (CBD) followed by an extremely Asn-rich linker region which separate the CBD and the catalytic domains. The latter is located at the C-terminus. The catalytic domain of CelF is highly homologous to CelA and CelC of Orpinomyces PC-2, to CelA of Neocallimastix patriciarum and also to cellobiohydrolase IIs (CBHIIs) from aerobic fungi. However, Like CelA of Neocallimastix patriciarum, CelF does not have the noncatalytic repeated peptide domain (NCRPD) found in CelA and CelC from the same organism.

  • Patent number: 6110720
    Abstract: A CDNA designated celE cloned from Orpinomyces PC-2 encodes a polypeptide (CelE) of 477 amino acids. CelE is highly homologous to CelB of Orpinomyces (72.3% identity) and Neocallimastix (67.9% identity), and like them, it has a non-catalytic repeated peptide domain (NCRPD) at the C-terminal end. The catalytic domain of CelE is homologous to glycosyl hydrolases of Family 5, found in several anaerobic bacteria. The gene of celE is devoid of introns. The recombinant proteins CelE and CelB of Orpinomyces PC-2 randomly hydrolyze carboxymethylcellulose and cello-oligosaccharides in the pattern of endoglucanases.

  • Patent number: 5669319
    Abstract: A waste fabric and lint collector and a cut thread chute assembly for use with an overlock stitching type sewing machine, comprising a collector box, including a front wall, two opposite lateral side walls, and top and bottom walls, a large see-through window forming part of the front wall thereof. The collector box is pivotally mounted in a releasable fashion to the sewing machine frame, wherein the front portion of the trimmed fabric and lint outlet is substantially closed by the collector box. A tubular coupling member has an inner end portion of a shape complimentary to that of the top wall of the collector box, for releasable interlocking engagement therewith, and an outer end portion, for releasably coupling with a complementary flexible air suction conduit for discharge of the lint to a waste container. The chute consists of: an elongated tube, having an enlarged transversely opening mouth at one end, and a smaller axially opening outlet port at the opposite end.
