Title: Enzymes modifiees et leur utilisation pour la synthese de thioglycosides
Inventor: WITHERS STEPHEN G
IPC: C12N9/24
Filed: 2003-09-12
Abstract: Des glycosidases mutantes dans lesquelles l'acide aminé dans le site actif servant de catalyseur acide, base ou acide/base est converti à partir d'un acide carboxylique en un autre acide aminé (par exemple un alkyle simple, comme dans l'alanine ou la glycine) peuvent catalyser la réaction d'un accepteur de thio-sucres et d'un donneur activé pour former un thioglycoside. Les 'thioglycoligases' constituent une nouvelle classe d'enzymes mutantes et font l'objet d'un premier aspect de l'invention. Les thioglycoligases peuvent être utilisées d'après le procédé selon l'invention pour coupler un accepteur de thio-sucres et un donneur activé de façon à former un thioglycoside. Par sélection de l'espèce du donneur et de l'espèce de l'accepteur et de l'enzyme spécifique employée, des thioglycosides présentant des structures et des stéréochimies différentes peuvent être obtenus.

Abstract: A video display employs a flat surface upon which is displayed more than one set of thin, blinking light emitting sites.  A transmissive light valve in front of the surface is capable of displaying images by means of varying the transparency of individual picture elements arranged in a grid pattern across its surface, and of displaying different images as different sets of light emitting lines blink on. The surface and light valve are arranged in such a way that an observer always sees each of the light emitting lines through one set of pixels with the left eye and another set of pixels with the right eye. The display is normally an autostereoscopic display, but it can be also made as a high resolution two dimensional display.

Title: Vacuum held crawler
Inventor: NAGATSUKA KENICHI
IPC: B25J5/00
Filed: 1990-06-11
Abstract: A B S T R A C T      A vacuum held crawler capable of substantially reducing frictional resistance between a wall of a building and the crawler, thus increasing the efficiency and reducing the power required for driving the crawler.  A flexible seal member is arranged so as to surround a recess of a vacuum chamber and vertically project by a suitable length from the bottom of the vacuum chamber.  A low friction member is mounted on the distal end of the seal member.  The seal member and low friction member have thin walls.  Such construction permits the flexible seal member to be in close contact by means of the low friction member with the wall while being held on the wall by the low friction member by suction, thereby preventing the bottom of the vacuum chamber from coming into contact with the wall.

Title: Vertical phase adjust circuit
Inventor: RANDALL JENNIFER L
IPC: H04N5/073
Filed: 1990-07-31
Abstract: A vertical phase adjust circuit with high noise immunity for line locked surveillance cameras.  To prevent noise from the AC line producing false output signals, a counter is used to lock out the delayed vertical line locked output signal.  The horizontal scan frequency is counted from the time a vertical output is produced, and the vertical output signal is prevented until 98 percent of the period between legitimate vertical signals has elapsed.  The circuit also includes a lock detect circuit to increase the time window during startup conditions to assure initial synchronization and an increased phase adjust range to permit synchronization with any other camera.

Title: Workpiece coated with a solid solution layer, method for its production, use of the workpiece, and apparatus for carrying out the method
Inventor: SCHMID ROLAND
IPC: C23C14/06
Filed: 1990-08-09
Abstract: A solid solution layer (C, D) of metalloids is applied on a workpiece by a reactive physical coating technique and has an inclusion ratio of the metalloids which varies continuously over the thickness of the layer. The solid solution layer (C, D) lies on a separating layer (B) on the workpiece. To produce the mixed layer (C, D) titanium is vaporized in a vacuum chamber in a crucible which is moved back and forth in front of the workpiece surfaces to be coated, and two gases are introduced which have different affinity to the vaporized titanium . For the creation of a first partial layer (C) of the solid solution layer (C, D) the inclusion ratio of the gases is varied steadily. During the coating operation the workpieces rotate, so that sometimes their surface is turned toward the crucible and sometimes away from it. The coated workpieces are distinguished by a high resistance to flank wear and cratering (Fig. 3).

Title: Digestively hydrolyzable low calorie edible oil substitutes
Inventor: CHRISTENSEN STEPHEN B
IPC: A23L33/20
Filed: 1990-11-29
Abstract: ABSTRACT     Reduced calorie food compositions are produced by replacing at least a portion of the fat content of a conventional food with an improved low calorie edible oil substitute that does not have a laxative effect. This substitute is an esterified form of polymerized C18 unsaturated fatty acids that has the property of being at least partly hydrolyzed by the processes of intestinal digestion into simple alcohols and polybasic acids.  These polybasic acids are of sufficient molecular weight that they are substantially not absorbed by the intestine, and are thus non-caloric. Since only the alcohol portion contributes calories, the ester as a whole has reduced caloric availability as compared to triglyceride oils.  Additionally, the edible oil substitute of this invention has the property of being altered in physical form by said intestinal digestion from an oil of low viscosity into either an oil of high viscosity.  This change in physical form is 37,079-F     sufficient to avoid the laxative effect common to most low calorie oils.     37,079-F

Title: Fused fiber optic coupler
Inventor: DAHLGREN ROBERT P
IPC: G02B6/287
Filed: 1990-12-20
Abstract: A fiber is mounted with a bare portion extending between two blocks. Four blocks securing a pair of fibers in this manner are mutually aligned by one or more external sleeves, and the fibers are fused and drawn to form a coupler of defined coupling ratio. One sleeve then slides over all four blocks and is bonded to constitute a rigid housing surrounding the fusion region. A preferred coupling block is a grooved D-rod, and different geometries are shown to provide effective PZ and PM fusion couplings, with fiber stress axes aligned with respect to a flat surface of the rod. Portions of the rod provide fiber support and alignment during fusion, and break away from the assembled coupler when complete.

Abstract: A suitable number of cords are supplied from a cord feeder to an extruder, passed through the crosshead of the extruder and coated with a raw rubber material. The rubber-coated material is pulled by a pull roll assembly disposed downstream from the extruder and wound up on a take-up assembly disposed downstream from the pull roll assembly. The winding speed of the take-up assembly is adjusted in accordance with the line speed and the variation in the diameter of wound-up coated material. A liner is supplied from a liner feeder to the take-up assembly and interposed between the portions of the coated material wound up. When the liner being drawn out for use in winding the rubber coated cords around the take-up drum approaches its rear end, another new liner is arranged so as to adhere automatically to the running liner without making any stop to the rubber coating operation.
