Abstract: A high-pressure system for hydroshaping a hollow workpiece has a lower die and an upper die vertically shiftable above the lower die and forming therewith a cavity shaped to hold the workpiece. An upper actuating element bears downward via a vertically compressible hydraulic operating cylinder on the upper die. A spring-loaded pressure-storing cylinder is connected by a hydraulic line to the operating cylinder and to the workpiece. Downward shifting of the actuating element first closes the dies together, then internally pressurizes the workpiece via the line from the operating cylinder such that the workpiece deforms and shapes itself to the cavity, and then fills the spring-loaded pressure-storing cylinder. Subsequent upward shifting of the actuating element at first allows the pressure-storing cylinder to empty, and then entrains the upper die upward off the workpiece by the actuating element.

Abstract: A method of producing high quality GaN powder by combining high purity gallium and high purity ammonia in a tube reactor under controlled conditions. A reaction between the ammonia and gallium under the controlled conditions produces a porous gallium melt and to a full reaction, yielding high purity crystalline GaN powders with a stoichiometric nitrogen concentration and a hexagonal wurtzite structure.

Abstract: The CCUTTER is an innovative ophthalmologic surgical instrument that greatly facilitates the performance of cataract surgery. Cataract surgery is the most frequently performed surgery in the United States, with over one million cataract surgeries done each year. A cataract is a clouding of the eye's internal lens, which interferes with the individual's ability to see clearly. During surgery, a continuous circular tear (called capsulorhexis) is made in the anterior capsule of the crystalline lens of the eye, and the front surface of the cataract is opened to allow access to the clouded tissue inside. The cloudy portion is then removed, leaving the thin clear back surface of the lens (called the posterior capsule) in place. A lens implant is then placed in the shell of the natural lens, and the incision is closed. The CCUTTER is designed to improve the predictability and consistency of performing the capsulorhexis during cataract surgery.

Abstract: The invention relates to derivatives of azithromycin, processes for the manufacture thereof and pharmaceutical compositions thereof preferably together with azithromycin.

Abstract: An apparatus for hydraulic high-pressure forming of a sheet, the apparatus having a top tool and a bottom tool as well as at least one pressure generating unit arranged between the press ram of a mechanical press and the top tool and uses a pressurized medium from the pressure generating unit as a working fluid for hydraulic preforming of the sheet. Contact faces of the tools directly engage with the sheet surface along the clamping area thereof and act to seal off the forming area that are subjected to the working fluid solely by contact sealing.

Abstract: The sun visor comprises a plate (1) for fastening to the bodywork of the vehicle and an arm (2) mounted in a hinged manner on the base (1), which in turn constitutes the means of assembly for the eyeshade of the sun visor. The arm (2) has a pair of conductive metallic elements (9) and (9?), located approximately parallel to each other and coated by means of an over-injected material, leaving the end (10) of such metallic elements (9–9?) uncovered to be able to establish contact with strips (7) foreseen in the hole (5) wherein the arm (2) is mounted in a hinged manner, whilst the other end of such elements (9–9?) in one case appears on the exterior in a terminal length (11) and in another of shorter length and defines a terminal end (12) which is uncovered on the arm (2), to be able to establish connection with a contact established on the actual eyeshade of the sun visor, for the enabling or disabling of the electrical device which can interact with said sun visor.

Abstract: The present invention relates to new processes for the preparation of gabapentin by the desilylation of a silylated gabapentin or by the silylation-desilylation of an acid addition salt of gabapentin with a silylating agent.

Abstract: Provided is a composition having a halogen-free polymeric material, a halogen-free flame retardant, and a coupling agent. Also provided is a method of making a tape containing the steps of forming the previously recited composition into a backing; and applying an adhesive to a surface of the backing to form the tape. When the tape is tested using UL 510 (7th Ed.), it has at least one of the physical properties: an elongation at break of at least 60%; a tensile strength at break of at least 1500 psi; a dielectric strength of at least 1,000 V per mil of tape thickness; an average adhesion strength of at least 0.175 N/mm; and a retention of at least 90% of an original average dielectric strength after the tape is conditioned for 96 hours in air with a temperature of 23.0° C. and a relative humidity of 96%.

Abstract: A tape which includes a backing and an adhesive layer on a surface of the backing. The backing includes a halogen-free polymeric material, a halogen-free flame retardant, and a coupling agent. The tape is flame retardant when tested according to Section 4 of Underwriters Laboratories UL 510, Seventh Edition.

Abstract: The present invention relates to a supporting module with waterproof seal for vehicle doors mainly comprised of a flexible laminar element (2) that can establish a waterproof seal between the wet and dry sides of the door (1), also meant to facilitate the mounting tasks of each component. The flexible laminar element has a sufficient supporting capacity to allow a preliminary mounting on it of the various door components for a subsequent installation of the entire assembly on the door in a single operation; however, the strength and structural capacities of the door continue to rely on its reinforcements and ribs, and not on the flexible laminar element, thereby allowing a cheaper and simpler laminar element and assembly as a whole.

Abstract: A metallic component is made by heating with subsequent hardening by rapid cooling. In the component unhardened regions remain, in that the component is electrically resistant heated and defined regions, either by partial resistance heating of the other regions, by overbridging or by cooling are excluded from heating above the austenitization temperature so that after a subsequent hardening process, they will remain with a ductile structure.

Abstract: An electrode pattern is used to apply preheating and final heating electric current to a workpiece whose smaller regions are bridged, or otherwise controlled as to the temperature so that for the final heating, all parts of the workpiece have substantially the same temperature and hence substantially the same electrical conductivity.

Abstract: Apparatus for sealing an end portion of a tubular workpiece in a mold for internal high-pressure forming of the workpiece, includes a housing having a pressure compartment in fluid communication with an interior space of the workpiece. Hydraulic high-pressure fluid is supplied from a pressure source to the pressure compartment by a pressure application unit which further includes a pressure piston received in the pressure compartment and defined in the pressure compartment by an effective piston area which is greater than a cross sectional area in the interior space of an end portion of the workpiece. At least indirectly connected to the pressure piston is a sealing mandrel which interacts with the end portion of the tubular workpiece. A check valve is disposed in a passageway between the pressure compartment and the interior space of the workpiece for blocking in a direction to the pressure compartment.
