Title: Paste for forming internal electrode in a ceramic element
Inventor: YONEZAWA MINORU
IPC: H01B1/22
Filed: 1999-02-10
Abstract: The present invention provides a paste for forming an internal electrode in a ceramic element. The paste causes no sudden heat generation from an organic vehicle contained therein during a degreasing step and allows Pd or Ag/Pd serving as an internal electrode to expand freely as a result of oxidation during a firing step, to thereby prevent structural defects of the ceramics such as delamination, when used for the formation of internal electrodes in a ceramic element such as a laminated ceramic capacitor. The paste contains a metal powder of Pd or Ag/Pd, Pd resinate, Cr resinate, and an organic vehicle. Preferably, the Pd resinate contains sulfur in the molecule. Also preferably, the paste contains the Pd resinate in an amount of 2.0-3.0 parts by weight as reduced to Pd, based on 100 parts by weight of Pd in the metal powder, and the Cr resinate in an amount of 0.03-0.12 parts by weight as reduced to Cr2O3, based on 100 parts by weight of the metal powder.

Inventor: PLUNKETT TOM
IPC: F16J15/08
Filed: 1999-03-02
Abstract: An improved three layer metal gasket is disclosed incorporating both primary and secondary combustion seals for increased combustion seal area durability.  The gasket has three plates, a first plate, a second plate, and a third plate. The first and third plates have opposed sealing beads that form the secondary combustion seal. The first and second plates cooperate to position the primary combustion seal and the secondary combustion seal along a central axis such that in operation the opposed sealing beads compress equally, thereby further improving the durability of the combustion area of the gasket. The gasket may further include a fluid seal. Specialized coatings may be used to enhance the sealability of both primary and secondary combustion seals and the fluid seal.
Patent CA-2264995-A1 (CA)
Title: Spring loaded bushed wedgelock
Inventor: BECKER ROBERT O
IPC: F16B19/10
Filed: 1999-03-05
Abstract: The wedgelock of the present invention prevents the separation of structural members during drilling or other fabrication operations on structural assemblies with curved surfaces or thickness variations and precludes the formation of burrs and delaminations which might result from such separation. The wedgelock also permits more precise and repeatable hole and other feature fabrication by more precisely locating an alignment fixture, such as a drill plate, relative to a structural assembly upon which fabrication operations are to be performed. The bushed spring loaded wedgelock comprises a standard, commercially-available wedgelock modified by attaching a bushing within which a spring loaded spacer is telescopically mounted. Like a standard wedgelock, the bushed spring loaded wedgelock is inserted through collinear holes in a drill plate or other alignment fixture and a structural assembly to clamp the assembly to the fixture. Even when used with a structural assembly with curved surfaces or thickness variations, the bushed spring loaded wedgelock clamps structural members together by forcing a spring loaded spacer against the front surface of the structural assembly while the shoulders of the wedgelock arms engage the rear surface of the structural assembly. A variety of wedgelock sizes and designs can be constructed to accommodate a range of alignment fixture, tooling hole and structural assembly geometries.

IPC: A01K89/016
Filed: 1997-09-10
Abstract: The present invention relates to a device for fly fishing comprising a line reel (1) for reeling in the fly line when utilizing preferably single-hand rods for fly fishing, the line reel (1) comprising a line spool (18) which, via friction operation, is designed to be operated by a drive means initiated by the fisherman, the line reel (1) being preferably placed under one of the fisherman's upper arms while fishing and a turning wheel (30) cooperating with the line reel (1), which can be placed on the fly rod (3). The object of the invention is to eliminate the drawbacks of preparing the fly line and its hindrance during fishing, and primarily the drawback of the circumference of the line spool, of the fly reel, decreasing as the fly line is pulled out. This is achieved by the line spool (18) slipping in relation to the drive means, or rotating therewith, when the fly line (8) is pulled out, held still or pulled in by the fisherman so that the unloaded part of the fly line (8) behind the fisherman's hand is reeled in onto the line spool (18), whereupon a turn or so of the fly line (8) can be placed around the wheel (30) the circumference of which thus remains constant when the line is pulled out or reeled in by the fisherman using the wheel (30).

Title: Method for producing dental castings and for producing a material for dental products, and the utilization thereof
Inventor: DOLABDJIAN HAIG
IPC: A61C5/00
Filed: 1998-12-03
Abstract: Common metallurgically produced materials are utilized in the production of dental products. During production, however, not all of the material can be utilized. When the material is subsequently processed by casting, a lot of energy is required for melting. The invention relates to a method for producing dental castings or a material for dental castings. According to the invention, fine particles of the material are to be partially fused and the fused particles are to be compacted. This results in a sintered semifinished product. During subsequent processing using casting techniques, this sintered semifinished product can be easily cast into dental castings in a pot of a casting device. The sintered semifinished product offers a good homogeneity during mechanical subsequent processing. The sintered semifinished products produced according to the inventive method are suited for all dental products which are produced by means of casting, especially for implant constituents, crowns, bridges and model casts.

Abstract: A hydrodynamic/aerodynamic amphibious aircraft (1) has a fuselage (10) with sponsons (100) extending outwardly and downwardly on either side of the underbelly (5) to define an inverted channel (15) having a substantially constant cross section. Each sponson has a forward portion (110) fixed to the fuselage and a movable aft portion (120). The aft portion tapers smoothly to a trailing edge (122). When the aft portion is in the flight position the forward and aft portions form a smooth low-drag symmetrical airfoil aerodynamic shape.      When the aft portion is raised a hydrodynamic step (112) is left on a lower surface of the forward portion, which turns each of the forward portions into a planing hull.
