Title: Apparatus and method for subcuticular stapling of body tissue
Inventor: GREEN DAVID T
IPC: A61B17/68
Filed: 1993-02-24
Granted: 2004-05-11
Abstract: A surgical apparatus for attaching two portions of cutaneous body tissue includes a pair of opposed elongated members having jaws which have tissue gripping members thereon at one end and which are movable toward each other to a closed position to engage two body tissue portions positioned within the members to move the body tissue portions into close approximation. Manually gripping systems of several alternative configurations are provided to actuate a mechanical transmission system to close the jaws. In a preferred embodiment, a fork is movable from a first position to a second position by manually operable devices to move the jaws toward each other. A pair of cam faces is located adjacent the opposite ends of the jaws. As the fork moves to its second position, the tines of the fork engage against the cam faces to move the opposed jaws to their closed position. A plurality of rod-like fasteners are carried in a stacked configuration proximally of the jaws such that when the jaws are in their closed position and the two body tissue portions are held in close approximation. Each rod-like fastener is movable to a position in ingress to penetrate the body tissue portions to attach the body tissue portions together. In another preferred embodiment, the elongated members are biased outwardly by a coil spring and a unique plate-like fastener drive member is provided to facilitate driving a fastener after the jaws are closed. A fastener cartridge is provided with fasteners stacked in a sloped fashion and having a coil spring to bias the fasteners toward the ejection position. Another embodiment includes a rack and gear teeth arrangement for approximating the jaws and for firing the fasteners. The rack and gear teeth function somewhat like a linear analog of a set of rotary gears. A method of attaching cutaneous body tissue portions is also disclosed.

Abstract: La présente invention concerne un procédé de traitement des effluents d'ateliers métallurgiques, par exemple d'usines de fabrication automobile, lequel procédé comporte un bioréacteur renfermant des micro-organismes vivants. Ce procédé peut être utilisé pour traiter des effluents renfermant des graisses et des huiles relativement faciles à biodégrader, des graisses, des huiles et des liquides synthétiques beaucoup plus difficiles à biodégrader, et des matières non biodégradables, notamment des particules inorganiques fines, par exemple de métal ou de carbure de silicium. Ces effluents nécessitent des temps de séjour du liquide et des solides dix fois plus longs que dans le cas des eaux d'égouts. Le procédé selon cette invention autorise une séparation efficace des solides en suspension, qui sont extraits du réacteur à un débit à peu près constant puis sont acheminés vers une membrane d'ultrafiltration. Le concentré est retourné au réacteur, sauf pour la purge périodique des solides. Les membranes ont une longue vie utile malgré une importante variation du débit de perméation, grâce au recyclage du perméat, qui permet le fonctionnement du réacteur à un volume constant, l'alimentation du réacteur à un débit constant, et le fonctionnement des modules filtrants à une pression relativement faible et constante. Le recyclage du perméat diminue de moitié la capacité (volume) de bioréacteur requise. L'efficacité et la durabilité des membranes filtrantes sont assurées par le préfiltrage (au moyen d'un tamis de 140 mailles) des particules de diamètre supérieur à 106  m. Des essais pilotes de traitement d'effluents d'usines de fabrication automobile, s'échelonnant sur une période de plus d'un an, ont révélé l'efficacité étonnante de ce procédé considérée à long terme.

Title: Recombinant cells that highly express chromosomally-integrated heterologous genes
Inventor: INGRAM LONNIE O
IPC: C12N15/01
Filed: 1991-12-04
Granted: 2010-08-03
Abstract: Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.

Abstract: A negative monitoring device comprising a CCD camera, and a line sensor is incorporated in a 3-D stereograph printing equipment.  Images on a negative are taken in the printing equipment, and then, the coordinates are designated on a TV monitor.  Thus, the spatial parallax of each projected negative image is measured.  When the variation of the parallax by the photographing location is small, the exposure pattern is so determined to form an image band having a band width and a band pattern which makes the photograph stereoscopic by combining the negatives having a large distance between the position.  The displacement of a key subject on the main object of each negative is measured. The exposure position is corrected in accordance with the result of the measurement.  When the displacement of the key subject on the main object is greater that the threshold value, it is judged that the main object is in the foreground.  A corection is made to suppress the parallax of the object in the background view, thus executing the positioning and exposure.  On the contrary, when the displacement of the key subject on the main object is smaller that the threshold value, it is judged that the main object is in the distant view.  A correction is made to suppress the parallax of the object in the foreground, thus executing the positioning and exposure.  If no main object can be specified in a landscape photograph or the like, an arbitrary position is selected as a key point for the measurement of the displacement, thus a correction is made.  In consideration of the difference in parallax between the objects in the foreground and background, a 3-d stereograph printing equipment can print stereographs having desiable spatial parallax, stereoscopic sense and picture quality.

Title: Silicon or silica substrate with a modified surface, process for producing the same, new orthoesters and process for producing the same
Inventor: GUIDOTTI BRUNO
IPC: C01B33/02
Filed: 1993-07-06
Granted: 2001-01-30
Abstract: The silicon or silicon dioxide substrate of the present invention have a novel modified surface which is occupied by the alcohol moiety of an orthoester. Said alcohol moiety can be saturated or unsaturated. The modification is effected by treating the surface of the substrate with an orthoester.      Thereby, the water is eliminated by hydrolysis form the surface, and the formed alcohol or silylether therafter takes the place of the water. Particularly suitable are new orthoesters of the general formula R1C[OCH2-CH2-O-CO-CH2CH2]3, wherein R1 is hydrogen or a cleavable organic residue, and R is (CH2)n, n being an integer form 1 to 18, and new orthoesters of the general formula (see formula I) wherein R1 is hydrogen or an organic residue, R3 is hydrogen or an alkyl group of 1 to 6 carbon atoms; and R4 is hydrogen, an alkyl group or a phenyl group. The modified surfaces have an increased boundary or contact angle and thus a reduced wett-ability. Moreover, they can react via reactive substituents with other monomers or polymers. This kind of surface modification advantageously replaces the silanization used so far for glass and other silicates.

Granted: 2004-10-19
Abstract: A recording and/or reproducing apparatus for recording and/or reproducing digital audio signal on a recording medium such as a magnetic tape, which includes a recording and/or reproducing unit, an analog-to-digital convertor, a decimation filter, and noise shaper. The recording and/or reproducing unit records and/or reproduces signal on a recording medium at a speed double relative moving speed of a head and the recording medium at least. The analog-to-digital convertor converts input analog audio signal into digital signal with a sampling frequency which is above the audio frequency band, and sufficiently higher than the maximum frequency capable of recording by the recording and/or reproducing unit. The decimation filter reduces the sampling frequency of the digital signal output from the analog-to-digital convertor, and converts it into digital signal of m-bit (m > n). The noise shaper converts the digital signal from the decimation filter from m-bit to n-bit, and then in requantizing, shapes noise so as to suppress within the audio frequency band, and supplies it to the recording and/or reproducing unit.
