Title: Metallic oxide-oxirane polymers and prepolymers
Inventor: KEEHAN DONALD J
IPC: C08G59/32
Filed: 1990-01-18
Granted: 1998-04-14
Abstract: The present invention relates to a novel oxirane prepolymer comprising the catalyzed reaction product of an inorganic oxide having at least one hydrolyzable oxygen with a difunctional oxirane oligomer having at least one aromatic moiety and at least one oxirane containing aliphatic moiety, characterized in that substantially all of the hydrolyzable oxygen atoms in said oxide are bonded to said oligomer and there is substantially no bonding between oligomer moieties.  By forming the prepolymers, and reacting all the inorganic oxide functional groups with a portion of the oxirane groups, prior to final polymerization, it is possible to obtain enhance properties in the final polymer such as heat deflection temperature, chemical resistance, toughness, tensile-flexural strengths, as compared to polymers formed by mere physical blending and direct polymerizing of the same oligomers, oxide filler, catalyst, hardener or initiator.  The present invention also relates to a novel inorganic oxide containing polymer, said polymer comprising at least three crosslinked prepolymer moieties, each said prepolymer moiety being the reaction product of an inorganic oxide having at least one hydrolyzable oxygen with a difunctional oxirane oligomer having at least one aromatic moiety and at least one oxirane containing aliphatic moiety.  Oxirane oligomers are useful for meeting high preformance needs in fabricating structural composites, protective coatings, adhesives, castings, laminating, electrical potting compounds and the like.

Title: Knuckle pin retainer for railway vehicle coupler
Inventor: ALTHERR RUSSELL GEORGE
IPC: B61G3/06
Filed: 1990-10-18
Granted: 1998-12-22
Abstract: An improved railway vehicle coupler head is provided having knuckle pin retaining means which are free to fully rotate with the knuckle pin to enable continuous rotation of the knuckle pin during use.  An elastic ring located within a circumferential groove on a bottom portion of the knuckle pin precludes the knuckle pin from unintentional upward removal during use while allowing for continuous rotation therewithin.  The continuous rotation of the knuckle pin allows for the distribution of stress about the circumference of a knuckle pin resulting in a longer fatigue life for the knuckle pin.

Filed: 1991-05-07
Granted: 1997-01-28
Abstract: In a raster output scanner, a method of switching video from one raster to the next during a scan without the creation of a visible artifact. A position encoder is used to determine the position of each raster on the photoreceptor, a first distance above the transition point and a second distance below the transition point, in the process direction. Above the first point the video will  be supplied by the first raster, and below the second point the video will be supplied by the second raster. From the first point to the transition point the duty cycle will vary from 100 % of data from the first raster to 50% from each raster. From the transition point to the second point the duty cycle will vary from 50% to 100 % supplied by the second raster. In this way, there is a gradual, and invisible, transition from one raster to the next.

Abstract: Un tablier escamotable pour couvrir de façon continuelle le puits d'un vérin à empattement variable servant à élever en concert avec un vérin fixe des véhicules de différentes longueurs comprend deux séries de panneaux articulés positionnées de part et d'autre du vérin au niveau du plancher afin de recouvrir en totalité l'ouverture du puits. Les panneaux articulés sont guidés horizontalement au niveau de l'ouverture par des guides horizontaux montés sur les murs longitudinaux du puits et, à chacune des extrémités de ce dernier, par des guides arqués et ensuite projetés vers le bas servant également à accommoder l'excédent de panneaux articulés selon la position relative du vérin le long de la chambre. Ainsi, lorsque le vérin est déplacé horizontalement dans la chambre, il entraîne les deux séries de panneaux articulées, certains panneaux émergeant de la chambre à l'une de ses extrémités alors que d'autres panneaux s'escamotent dans celle-ci à son autre extrémité. Par conséquent, le tablier recouvre de façon continuelle l'ouverture pratiquée par le puits pour toutes les positions du vérin dans la chambre. Les panneaux articulés s'engagent dans les guides au moyen d'essieux porteurs qui servent également d'articulation entre chaque paire de panneaux successifs.

Filed: 1991-07-10
Granted: 2003-09-30
Abstract: A method of passively aligning optical receiving elements such as fibers to the active elements of a light generating chip includes the steps of forming two front and one side pedestal structures on the surface of a substrate body, defining a vertical sidewall of the chip to form a mating channel having an edge at a predetermined distance from the first active element, mounting the chip epi-side down on the substrate surface, and positioning the fibers in fiber-receiving channels so that a center line of each fiber is aligned to a center line of a respective active element. When mounted, the front face of the chip is abutting the contact surfaces of the two front pedestals, and the defined sidewall of the mating channel is abutting the contact surface of the side pedestal. The passive alignment procedure is also effective in aligning a single fiber to a single active element.

Title: Atherectomy cutter with a positive attack angle
Inventor: RADISCH HERBERT R JR
IPC: A61M25/00
Filed: 1992-09-09
Granted: 1999-06-01
Abstract: A rotatable atherectomy cutter is provided with a body and a pair of blade elements.  The blade elements are mounted on the periphery of the body and extend distally therefrom in a linearly convergent manner.   Each blade element has a flat planar outer face with two linear longitudinally-exposed edges, one of which is defined as the cutting edge and the other of which is defined as the trailing edge.   The cutting and trailing edges are positioned at a maximum radial distance from the axis relative to the remainder of the blade element to define the outermost rotation surface of the blade element. Accordingly, contact between the blade element and the stenosis is limited to the edges during rotational operation of the cutter, while a clearance is maintained between the stenosis and the outer face.  The clearance defines a positive attack angle that enables the cutting edge to more effectively cut away the plaque of the stenosis.

The band is rotated by at least one pair of rollers which are in frictional contact with the band. Aircraft stability is controlled by regulating airfoil pitch which is responsive to pivoting of a control ring. Alternatively, aircraft stability is provided by regulating the flow of air or gas from a plurality of nozzles disposed about the aircraft. The body. a portion of which may be located inside the lifting assembly, includes a passenger and load carrying compartment and an engine assembly.
