Abstract: A device for plasticising thermoplastic materials has a revolving feed screw for plasticising the plastic materials within a housing. The plastic materials to be plasticised are supplied to the feed screw by a feeding device through a feeding hole in the housing. The housing of the feed screw is provided on its inner wall with at least two broad pockets. These pockets extend in the longitudinal direction of the feed screw and are mutually separated by narrow ribs, when compared to the width of the pocket. One pocket is open towards the feeding hole, the other pockets are sealed against the feeding hole by at least one rib of the housing of the feed screw. In order to improve filling of the feed screw, a feeding device for the plastic materials to be processed is associated with the feed screw. This feeding device stuffs the plastic materials into the feeding hole of the housing of the feed screw with a component of motion normal to the longitudinal axis of the feed screw. The depth of the pocket open towards the feeding hole is at least constant, seen in the direction of rotation of the feed screw. Alternatively or in association therewith, one of the ribs may be adjustable, to allow the feeding capacity of the feed screw to be modified according to the plastic materials to be processed.

Abstract: A removable nosepiece (100, 200, 300) for a chuck (20, 20') or other similar tool holder has an outer ring (110, 210, 310) of relatively hard and inflexible material such as plastic and/or metal and an inner ring (120, 220, 320) of relatively soft and flexible material such as rubber. The outer ring releasably holds the nosepiece on the distal end of the chuck or other tool holder. A tool is inserted into the chuck or tool holder through a central aperture in the inner ring. The inner ring engages the sides of the tool to help keep dust and debris out of the chuck or tool holder. The nosepiece can be removed and replaced when it becomes worn (e.g., when the inner ring is no longer functional).

Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer having a functionality selected from the group consisting of a hydroxyl; a polylhydroxyl; an aromatic ring; a carbonyl; a carboxylic acid; a polycarboxylic acid; an aldehyde; a ketone; an amine; an amide; an ether; an ester; and mixtures thereof, to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water), up to about 100 .ANG. and preferably in the range of about 10-45 .ANG., so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.

Title: Completion sub-sea test tree
Inventor: EDWARDS JEFFREY CHARLES
IPC: E21B34/04
Filed: 1996-05-10
Abstract: A dual bore completion sub-sea test tree (10) is described which has main bore (18) and an auxiliary or annulus bore (20). Two identical ball valves (22, 24) are located in series within the main bore (18) and two smaller identical ball valves (26, 28) are located in series in the annulus bore (20). The ball valves (22, 24, 26, 28) are operated by respective independent control lines acting on the operating mechanisms of the respective valves within the test tree(10) to move the valves between open and closed positions to allow or deny communication through the respective bores (18, 20). The completion sub-sea test tree (10) provides isolation of the main bore (18) and/or the annulus bore (20) when required by application of hydraulic pressure to assist closure to spring forces sufficient to cut coil tubing in the event of an emergency situation requiring rapid disconnect. Hydraulic across the tree disconnect is achieved using independent hydraulic stabs which can selectively isolate or allow the hydraulic systems to vent when disconnected. A helical guide (82) and axial slot (81) are provided on the surface (16, 83) of the housing to engage with a pin (84) on a BOP stack to orientate the tree (10) correctly to a tubing hanger (86).

Abstract: Un système, un logiciel et une méthode pour déterminer l'impact différentiel d'un certain nombre de transactions potentielles sur l'évaluation de la valeur à risque (VAR) d'un portefeuille de négociations à l'intérieur d'un intervalle d'échange, sans avoir besoin de calculer une VAR particulière en fonction de chaque transaction potentielle. La méthode implique de calculer la VAR du portefeuille de négociations ainsi qu'une valeur vectorielle dérivée de la VAR. Pour chaque transaction potentielle, l'impact sur la VAR est équivalent au produit vectoriel du vecteur dérivé et du flux de trésorerie répertorié de la transaction potentielle. Un résultat négatif indique une diminution favorable de la VAR. Cette conclusion peut être étendue à n'importe quelle transaction potentielle sans avoir à recalculer la VAR. Le logiciel utilise cette méthode dans la version améliorée d'une application d'analyse financière. Le système comprend le logiciel ainsi que des bases de données pour enregistrer les portefeuilles de négociations. De plus, la méthode et le système permettent de normaliser chaque transaction potentielle en fonction des critères sélectionnés, de sorte qu'un certain nombre de transactions potentielles particulières puissent être hiérarchisées selon leur impact différentiel sur la VAR afin de choisir celle qui réduit le plus la VAR.

IPC: C08L55/02
Filed: 1997-02-28
Abstract: Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain core/shell copolymers having a rubbery, preferably crosslinked core mainly of units derived from butadiene, and an outershell mainly of a copolymer of styrene and acrylonitrile. Such copolymers do notrequire the presence of functional groups capable of reaction with the hydroxyl groups of the poly(vinyl alcohol).

Abstract: A method for performing intrastromal photorefractive keratectomy in the cornea of an eye, using a pulsed laser beam, includes the initial step of focusing the beam to a focal spot at a selected starting point in the stroma. The starting point is located at a predetermined distance behind the epithelium of the cornea. While focused on the starting point, the laser beam is pulsed to disrupt a volume of stromal tissue which is substantially equal to the volume of the focal spot. Subsequently, the beam is focused in a patterned sequence to focal spots at other discrete points in the stroma. At each point the stromal tissue is photodisrupted. With this progressive pattern of photodisruption, each spot is placed substantially adjacent a volume of previously disrupted tissue. The resultant photodisrupted tissue creates a layer which is substantially centro-symmetrical around the optical axis. A plurality of layers can be removed to create a cavity in the stroma. When the cavity collapses, the corneal curvature is changed as desired.
