Title: Method for in-situ modernization of a heterogeneous synthesis reactor
Inventor: GUARINO GIUSEPPE
IPC: B01J19/30
Filed: 1999-01-06
Abstract: A method for in-situ modernization of a heterogeneous synthesis reactor, comprises the steps of providing an unperforated cylindrical wall (15) coaxial to the gas outlet wall (8) in a catalytic bed (6) of the radial or axial-radial type, the unperforated cylindrical wall (15) extending from an upper end (8a) of the gas outlet wall (8) for a portion of the same of a prefixed length, so as to define a free-space (16) between the gas outlet wall (8) and the unperforated wall (15), for the passage of a part of the gas leaving said catalytic bed (6), and of proving means of closing the free-space (16) between the unperforated wall (15) and the gas outlet wall (8), in proximity of the upper end (8a) of the latter, preventing thereby a bypass of the catalytic bed or a recycling to the same of the gas entering respectively leaving the reactor.      Thanks to the above steps, the present method allows to operate with a reduced amount of catalyst in the catalytic bed, keeping however the fluid dynamics and pressure drop characteristics unchanged.

Title: Method and apparatus for treating raw food
Inventor: MORGAN ARTHUR JR
IPC: A23L3/16
Filed: 1999-05-19
Abstract: The present invention is a surface pasteurizer and method for treating the surface of raw foods, by means of exposing the surface to a treatment gas in the absence of air, so rapidly and ending the treatment, by streaming the treatment gas back into vacuum, so rapidly that the interior of the food is unaffected by treatment and so that the pasteurizer is able to process a high volume of food in a given time period.      The treatment may have for its object (1) killing surface microorganisms on such items as meat, seafood, fruit, vegetables, and packaging materials; (2) firming the surface layer over a sensitive interior on such items as encapsulated liquids, permeation membranes, and edible coated objects; or (3) weakening the surface layer over a sensitive interior in order to more easily remove the surface layer on such items as peeled grains, fruit and vegetables. The apparatus and method provide for (1) inserting the food into the apparatus, flushing the food with low pressure air-free steam during insertion; (2) exposing the food to a vacuum; (3) exposing the food to an air-free treatment gas; (4) exposing the food to a vacuum to remove the air-free treatment gas; and (5) expelling the food from the apparatus.

Inventor: LILLELUND STIG
IPC: A47J47/04
Filed: 1999-07-26
Abstract: A container for storing items, such as foodstuffs. The container includes a sidewall which includes a monolithic window portion having greater transparency than the remainder of the sidewall. This is achieved by forming the container of a clear, tinted material, and forming the window portion with a reduced thickness, and/or forming the window portion with a smooth surface and forming the remainder of the sidewall with an obscuring texture. A cover may be used to close the container, and may form a seal with the container. The cover may include pivot pins to permit the cover to be pivoted to a position breaking the seal, thus permitting easier removal of the cover. A pouring insert may also be used with the container. The pouring insert is mounted to the mouth of the container, and includes a main pour spout and a secondary pour spout.  Both pour spouts include pour guides to direct spilled contents back into the container. A  hinge in the pouring insert permits a first section to remain in position while a second section is folded therebeneath. The second section may be secured in this position, forming a scooping aperture.

Title: Formation of superconducting devices using a selective etching technique
Inventor: MA QIYUAN
IPC: H01L39/24
Filed: 1998-01-21
Abstract: A method for forming a superconducting device (232) using a selective etching technique on superconducting thin films. The method utilizes rapid etching which combines ion implantation with chemical etching. The portions of the superconducting film to be retained are masked (215) from the ion implantation process (217). The chemical etching process then removes the implanted portions (225, 227) of the superconducting film at a much faster rate than the portions (223) not implanted so that only the un-implanted portions (223) remain. The resulting superconducting devices can be used, e.g., as nanostructures and nano tips, bolometers, multilayer RF coils, microwave waveguides and filters.

IPC: G01N33/49
Filed: 1997-10-16
Abstract: A method is disclosed whereby the concentration of a blood substitute, such as cross-linked hemoglobin, in a serum or plasma specimen is rapidly and accurately identified and quantified. The method further takes the measured concentration of the blood substitute and uses it to correct for its effect, if any, on a measured analyte concentration, e.g., serum/plasma total protein.

Patent CA-2284081-A1 (CA)
Inventor: RIBBING ROBERT B
IPC: B22D11/10
Filed: 1999-09-27
Abstract: A reservoir for molten metal is provided whereby the continuous filling of molds with such molten metal is allowed. Ladles of molten metal are utilized to provide such molten metal into one side of the reservoir. When such ladle is emptied and removed from pouring contact with the open side of the reservoir, the reservoir itself holds enough molten metal to allow molds to be continuously placed into a pouring station to receive molten metal from the closed side of the reservoir. A new ladle filled with molten metal can be brought into position to begin filling the open side of the reservoir with molten metal without interruption to the filing of molds at the closed side of the reservoir. A refractory baffle is utilized to separate the reservoir into an open side and a closed side. The reservoir is especially designed for bottom pressure filling of such molds with molten metal.

Title: Orthodontic appliance
Inventor: TAKEMOTO KYOTO
IPC: A61C7/14
Filed: 1999-02-19
Abstract: When an orthodontic appliance is attached to the lingual side (back side) of teeth which is invisible from the outside, a large difference in level of the surface between adjacent teeth requires utilization of a wire bent in a complicated fashion. It has been found, however, that the difference in level between adjacent teeth is very small in a horizontal plane at a boundary between a crown and a root, thereby making it possible to draw a smooth envelope therealong. Based on this finding, with a view to placing a wire along such an envelope, a "lingual straight archwire" having a planar configuration comprising a simple curve and straight lines smoothly connected to ends of the curve and residing in a single horizontal plane and a bracket having a configuration suitable for the placement of the archwire are provided.
