Title: Process for separating hf from its mixtures with hydrochlorofluorocarbons 123 and/or 124
Inventor: SOLINAS GIAMPAOLO
IPC: C01B7/19
Filed: 1993-12-07
Granted: 2004-10-26
Abstract: The invention relates to a process for separating HF contained in liquid mixtures comprising HCFC 123 and/or 124. The mixtures, enriched in C2C14 up to a content of such compound of 20-75% by weight, is subjected to a treatment for separating liquid phases, thereby obtaining an acid phase very rich in Hf and an organic phase impoverished in HF, which is subjected to a flash, so obtaining a liquid phase containing 123, 124 and C2Cl4, having a very low HF content, and a gas phase enriched in HF. As an alternative to flash, a separation in a distillation column can be carried out.

Abstract: A joint between an upper wall part and a lower wall part of a modular tub/shower unit includes a recessed band adjacent to but spaced from the lowermost edge of the upper wall part. A further band is recessed at the uppermost edge of the lower wall part with the vertical height of that band being greater than the vertical height of the recessed band in the upper wall part and greater than a band at the lowermost edge which is not recessed. The lowermost band of the upper wall part is then adhesively attached to the uppermost edge and a part of the recessed band of the part by a double sided adhesive tape the covering of which is pulled through the gap between these parts. The adhesive tape provides the only sealant necessary for waterproofing the joint and provides the only structural strength necessary. The groove above the lowermost band of the upper wall part allows the upper wall part to be maneuvered into the required position by finger engagement into the groove.     The recessed bands adjacent the upper and lower edges of the parts provide stiffening strength. The parts are held together by a pair of spring clips the first of which snaps over the second when the parts reach the overlapped position as limited by engagement of the parts with the first also applying force to the second transverse to the joint to squeeze the adhesive.

Abstract: A repair process for blades of turboengines damaged in the head or edge regions in which the damaged regions are first separated to leave an undamaged blade stump with an exposed, repair surface.      The repair surface of the blade stump is prepared for butt welding and a repair plate of constant thickness which exceeds the maximum profile height of the blade by more than 50% is provided with a front surface adapted to the repair surface. This front surface of the repair plate is abutted against the repair surface and the blade stump and the repair blade are then butt welded. The weld joint and the repair plate are machined to the profile contour of the blade stump and to the desired blade profile. This process is used for the repair of blades of integral rotor disks of turboengines, particularly for blades of integral compressor impellers.

Title: Intraluminal stent for attaching a graft
Inventor: FRANTZEN JOHN J
IPC: A61F2/06

Granted: 1999-10-05
Abstract: A graft-and-stent combination is disclosed for deploying by an intravascular delivery system at the site of an aneurysm, the combination being expandable from a first diameter to a second, larger diameter to hold open and press the graft against regions of the body lumen just proximal and distal to the aneurysm. The combination is characterized by one or more stents that are flexible due to independently expandable and interconnected cylindrical elements, which provide sufficient radial strength to the combination when the graft-and-stent are being attached to the vessel, but which nonetheless afford sufficient resiliency to allow a great degree of expansion at a rapid rate when the combination is being deployed. Attachment elements in the form of hooks are provided to securely affix the ends of the stent extending distally and proximally of the graft after expansion to the walls of the vessel just distally and proximally of the aneurysm.

Abstract: A low VOC cleaner/primer for EPDM and Butyl roofing and waterproofing membranes. Highly volatile solvents are replaced with a carefully chosen petroleum oil and a blend of hydrocarbon resin and partially cross-linked halo-butyl rubber. The cleaner/primer contains about 3 - 5% by weight halo-butyl rubber, about 10 - 25% by weight of a high softening point resin tackifier, about 60 - 80% by weight of a low viscosity, high volatility petroleum oil and a curing agent. When applied to a dust covered membrane the cleaner/primer effectively displaces dust and leaves behind a primer film which is conducive to adhesive bonding by either splicing tape or solvent based adhesive. When applied in a thin coating to metal surfaces the cleaner/primer effectively primes the metal to enhance the adhesion of butyl rubber based splicing tape or solvent based butyl adhesives.

Title: Generic file format for multiple security requirements
Inventor: KOU WEIDONG
IPC: G06F21/62
Filed: 1996-07-29
Granted: 2000-02-15
Abstract: A generic secure file format to solve problems associated with secure storage and interchange. The file format allows multiple files to be wrapped into a single entity for storage or transmission interchange. Each file can have different security requirements from that of other files. Different file types can be interchanged under a single wrapper in this secure file format. The secure file format also allows one file to be divided into multiple sections and wraps them into a single file. Each section of the file has its own security protection. This enables only sensitive information to be protected, and leaves other sections with less or no security protection. This results in higher performance since security related operations are only required for a small portion of the file.

IPC: E06B3/673
Filed: 1996-10-23
Granted: 2004-03-02
Abstract: An applicator for applying a flexible tape to a planar sheet having a base, a table, a cradle and an applicator head. The cradle and the applicator head are carried by a carriage with the cradle and applicator head being rigidly attached to one another such that they move together. A number of motors are provider to move the carriage and interconnected applicator head through the Cartesian coordinate system relative to the table, and a fourth motor rotates the applicator head relative to the carriage. Another motor feeds flexible tape out from a spool, over a dancer arm and into the applicator head where a sixth motor drives the flexible tape adjacent the application zone. A sensor associated with the dancer arm measures the pressure or deflection in a cylinder connected to the dancer arm and forwards an analog signal to the fifth motor to increase the speed of the fifth motor if the dancer arm pressure is high, and decrease the speed of the fifth motor if dancer arm pressure is low. In a second embodiment, a new planar sheet may be fed onto the table while an existing planar sheet is acted upon by the applicator head.
