Title: Fuel cells stack
Inventor: SUGAWARA YASUSHI
IPC: H01M8/02
Filed: 1999-07-15
Abstract: In a polymer electrolyte membrane type fuel cell employing a high polymer ion exchange membrane as an electrolyte, a fuel cells stack is produced at a low cost by easily constituting flow passages for a fuel gas, an oxidizing agent gas and a cooling water which have been conventionally constituted by a cutting process being hard to process and hard to reduce a cost. The fuel gas passage, the oxidizing agent gas flow passage and the cooling water flow passage are constructed by a combination of a diffuser constituted by a conductive porous body or a corrugated plate and an elastic gasket, whereby a cutting process is not required, and a number of parts can be reduced and an operating performance can be improved by integrally forming the gasket with the separator, so that a cost can be reduced.

Inventor: ROBERTSSON MATS
IPC: G02B6/38
Filed: 1998-02-18
Abstract: In an optical flexfoil (1) comprising optical waveguides such as optical fibers (3) ends of the optical fibers can be located at inner and edge positions of the flexfoil. Cut-outs (7, 9) are formed around such fiber ends to form tabs (11, 13) which can be bent laterally from the plane of the flexfoil (1) so that the ends of the fibers (3) are located at the exterior edges of the tabs. This allows a connection of the optical fibers to external devices in different directions such as a connection in a direction perpendicular to the flexfoil (1). Thus, the flexfoil (1) can be used as an optical supplement to an electrical backplane (21), the tabs (11) extending through openings (29) in the backplane. Also, an easy handling of the flexfoil is achieved, since no connection tabs extending beyond the edges of the flexfoil are required. This is advantageous for example in polishing the ends of the fibers at the tab ends.

Abstract: In an arrangement for recreating a model, use is made of an original model (1) of implant and/or tooth remnants (2-5) in a system for producing a dental construction (32). The system includes a reading apparatus (10, 13) and a first levelling function (6). A reproduction of all or part of the original model is created in CAD equipment. The said dental construction is created in the CAD equipment, and the reproduction and the construction are divided up into parts whose axes of inclination and contact surfaces are identified in terms of position and direction. Replicas of the implant and/or tooth remnant parts and the construction parts are produced and mounted on a mounting member (23) after bore holes for the replicas of the tooth remnant parts have been established using boring equipment. The said bore holes are estabished by means of a second levelling function and the bore holes receive positions and longitudinal axis inclinations which correspond to the positions and the inclinations of corresponding axes in the original model. The replicas for the tooth remnant parts can be fixed in terms of angle of rotation in the mounting member with position-fixing members (identification members). The last-mentioned replicas form the recreated model on which the construction replicas can be applied.

Title: Method for preparing melamine
Inventor: TJIOE TJAY TJIEN
IPC: C07D251/60
Filed: 1998-05-15
Abstract: Method for preparing melamine from urea via a high-pressure process in which solid melamine is obtained by transferring the melamine melt coming from the reactor to a vessel where the melamine melt is cooled with an evaporating cooling medium. The melamine melt comes from the melamine reactor at a temperature between the melting point of melamine and 450 ~C and is sprayed into a cooling vessel, via spraying means, having an ammonia environment with an increased ammonia pressure and cooled by means of an evaporating cooling medium to form melamine powder. The melamine melt is thereby converted into melamine powder having a temperature of 270 ~C or below after which the ammonia pressure is released and the melamine powder is cooled, at least for part of the cooling range, by the powder being set in motion mechanically and being cooled directly or indirectly and, if necessary, the melamine powder is cooled further.

Abstract: A rotary blancher that is sealed such that it can be positively pressurized during operation to a pressure greater than the ambient pressure outside the blancher to increase food product heating speed and efficiency. The blancher has a sealed housing, a sealed food product inlet, and a sealed food product outlet all for enabling an atmosphere inside the blancher to be positively pressurized. A  heat transfer medium, such as a heated gas, a heated vapor, a heated liquid, or a combination thereof is introduced into the blancher to heat the food product inside the blancher. In one preferred embodiment, steam and hot water comprise the heat transfer medium. During operation, food products are continuously or substantially continuously introduced into the blancher through the food product inlet, continuously or substantially continuously processed by the blancher, and thereafter continuously or substantially continuously discharged from the blancher through the food product outlet. As a result, a greater amount of food products can be more quickly heated to a desired temperature using a blancher of this invention as compared to a blancher that is not sealed and pressurized.

Title: Highly asymmetric ultrafiltration membranes
Inventor: DITTER JEROME F
IPC: B01D67/00
Filed: 1998-07-07
Abstract: The present invention relates to highly asymmetric polymer membranes for ultrafiltration (UF), and to a simplified method of their manufacture.  Disclosed herein are UF membranes with a high degree of asymmetry between the size of pores at the skin face of the membrane and the size of pores at the opposite face of the membrane. Asymmetry ratios of these membranes range from about 20 to about 1000. The porous support layer bewteen the skin face and the opposite face is reticular and is substantially free of macrovoids. These membranes thus have higher flow rates than prior UF membranes. The membranes are cast from polymer dope mixes that are either homogeneous solutions or stable colloidal dispersions.

Abstract: A magnetic table game is disclosed wherein gaming pieces are movably mounted to a substantially non-magnetic playing surface of a game by a magnetic coupling device. The coupling device comprises a base mounted to the gaming piece, the base having a housing, a first and second magnet and a first support element positioned between the first and second magnets and further positioned to support the base on the surface. The base is held on surface by a magnetic coupling positioned on the opposite side of the surface. The magnetic coupling has a housing, a first and second magnet and a second support element positioned between the first and second magnets of the magnetic coupling and further positioned to support the base on the surface. The housings and the support members of the base and magnetic coupling are configured to position the magnets of the base in close proximity to the magnets of the magnetic coupling when the base and magnetic coupling are mounted to each other on opposite sides of the surface. The support members are made of a low friction material and are rotatably mounted to their respective housings by bearings. The gaming pieces are manipulated by moving the magnetic couplings via long lever arms which are operatively coupled to the magnetic couplings by gear drives. The gear drives convert the torsion of the lever arms into the rotation of the magnetic couplings, which in turn cause a corresponding rotation of the corresponding player piece.
