Title: Process for preparing cyclobutane-1,2-dicarboxylic esters
Inventor: BRUNNER ANDREAS
IPC: C07D309/12
Filed: 1998-06-30
Granted: 2007-09-04
Abstract: Cyclobutane-1,2-dicarboxylic esters of the formula:  (see formula I) in which R1 is a Cl-8-alkyl group, an optionally substituted mono- or bicyclic cycloaliphatic group having 3 to 10 ring carbon atoms, an optionally substituted aryl or arylalkyl group or an optionally substituted saturated heterocyclic group and R2 is either C1-4-alkyl or both radicals R2 together form a group of the formula -(CH2)n- (n = 2 to 4), are prepared from the corresponding maleic or fumaric ester and ketene acetal in the presence of a Lewis acid and a sterically hindered base. The reaction is stereoselective when an optically active maleic or fumaric ester is employed.  The cyclobutane-1,2-dicarboxylic esters (I), in particular those having trans configuration, are intermediates in the synthesis of pharmaceutically active compounds.

Title: Treating urinary and other body strictures
Inventor: ISSA MUTA M
IPC: A61F2/94
Filed: 1998-10-16
Granted: 2007-08-07
Abstract: A method and system for treatment of body strictures restores luminal diameter to normal range. The stricture is dilated, stretching its lumen to a desired diameter, collagen is exuded near existing tissue of the stricture and absorbed or adhered to the tissue, making a collagen-enhanced tissue stricture. Energy is emitted to ablate or harden the collagen-enhanced tissue. Treatment may be repeated, creating a hollow, cylindrical supported frame of layers of hardened collagen. Pressure from exuded collagen or from one or more expansion balloons dilates the stricture. The stricture is isolated by balloons at either or both ends of the stricture, isolating the stricture and confining the collagen. Collagen adheres to a stent, preferably tack-welded onto the stricture, which supports the stricture until the stent is absorbed into that tissue.

Abstract: The high speed fuse employs stamped end bell and terminals rather than forged or machined parts. A slot for the terminal is punched through the end bell. The terminal is inserted into the slot in the end bell and staked in position. This insures a strong tight fit without requiring welding or soldering. One end of each terminal has coined ridges to facilitate automatic welding of the fuse link to the terminals. Round balls are used to seal the fill holes for the arc quenching material. Metal pins secure the end bells within the fuse housing but are not electrically connected to the terminals because of the insulative end bells.

The sledge element (11) joint to the intermediate ring (2), slides along the track (9) as a result of vectoring around the axis (8). For vectoring around axis (6) the sledge element (12), joint to the inner ring (1) slides over the track (10).

Abstract: A system for tying a load down on a load deck. A  plurality of tie-down assemblies are spaced at a plurality of locations along the side sills. Each assembly includes a first aperture in a vertical wall of one of the side sills; a belt router recessed at a first point beneath the deck and between the side sills, immediately adjacent and inward of the one side sill; a second aperture in the deck, above the belt router; a first belt winder mounted at a second point on the one side sill, below the first aperture; a second belt winder mounted at a third point on the other side sill in alignment with the first belt winder; and, a belt having one end secured to the first belt winder.     To tie down a narrow load which does not project beyond the side sills, the belt's opposite end is extended through the first aperture and beneath the deck, around the belt router, through the second aperture and above the deck, over the load, and into engagement with the second belt winder. The belt is then be tensioned by winding it onto the first and second belt winders with the belt remaining flush against a top surface and at least one side surface of the load. The apertures and belt router are not needed to tie down a wide load which projects beyond the side sills; in such case, the belt's opposite end is extended over the load and into engagement with the second belt winder. The belt can then be tensioned by winding it onto the first and second belt winders with the belt remaining flush against a top surface and both opposed side surfaces of the load.

Abstract: In order to provide a metal gasket suitable for use for a flange made of synthetic resin, the metal gasket disposed between a resin flange and an aluminium flange is composed of two elastic metal plates, on each of which a half bead is formed, and which are superposed on each other to be jointed so that half beads are directed opposite to each other. Since bending in a state, where the gasket is tightened, can be suppressed to an extremely small value at a same level in the case where the flanges are tightened without gasket, it is possible to remove worsening in flatness (planarity) of the resin flange.

Title: A method of fabricating mirrors in polymer waveguides
Inventor: ROBERTSSON MATS
IPC: G02B6/12
Filed: 1999-03-08
Granted: 2007-09-04
Abstract: The position of an oblique mirror structure inside a polymer waveguide (1) i n relation to an optical device is accurately defined by using an integrated mask of metal which is defined using photolithography, o n top of the waveguide structure. When irradiating the surface of the waveguide with laser light, it is only let through where no metal is left, so that the recess (19) formed is defined by edges of strips (15) of the metal layer. In the same metal layer also electrical contact pad s (13) are produced used for self-aligning flip-chip mounting of devices such as lasers and photodiodes. Another metal layer (21) can be applied inside the waveguide structure at a place under the waveguide core so that it is hit by and stops the laser light. The energy of the laser will atomize the metal and the dispersed metal will then be deposited on the walls of the recess (19).
