Title: Single crystal sic and a method of producing the same
Inventor: HIRAMOTO MASANOBU
IPC: C30B29/36
Filed: 1998-11-06
Abstract: The single crystal SiC according to the invention is produced in the following manner. The surface 1a of a single crystal .alpha.-SiC substrate 1 is adjusted so as to have a surface roughness equal to or lower than 2,000 angstroms RMS, and preferably equal to or lower than 1,000 angstroms RMS. On the surface  1a  of  the  single crystal  .alpha.-SiC  substrate  1,  a polycrystalline .alpha.-SiC  film  2  is  grown  by  thermal  CVD.          Thereafter, the complex M is placed a porous carbon container 3, and the outer side of the carbon container 3 is covered with .alpha.-SiC powder 4. The complex M is subjected to a heat treatment at a high temperature equal to or higher than a film growing temperature, i.e., in the range of 1,900 to 2,400°C in an  argon  gas  flow,  whereby single  crystal  .alpha.-SiC  is integrally grown on the single crystal .alpha.-SiC substrate 1 by crystal growth and recrystallization of the polycrystalline .alpha.-SiC film 2. It is possible to stably and efficiently produce single crystal SiC of a large size which has a high quality and in which any crystal nucleus is not generated.

Title: Wideband external pulse cardiac monitor
Inventor: BLANK SEYMOUR
IPC: A61B5/0225
Filed: 1997-05-28
Abstract: This invention is an apparatus for assessing cardiovascular status of a mammal comprising a system (20) for locally applying a pressure to an artery, capable of restricting blood flow through said artery, a wideband external pulse transducer (26), having an output, situated to measure acoustic signals proximate to said artery, and a computing device (32) receiving said output for calculating, based on said output, a peripheral vascular impedance value.  The systolic and diastolic pressure are determined by an appearance and disappearance of a high frequency signal upon changes in cuff (10) pressure partially occluding arterial blood flow. The arterial pressure waveform is estimated by measuring the wide band acoustic emissions from a non-occluded artery. The peak and trough of the arterial pressure waveform are calibrated with the determined systolic and diastolic pressures. The systemic vascular resistance is computed by occluding blood flow with a supersystolic pressure, and calculating, based on a natural logarithm of a difference in amplitude between a first major systolic peak and first major systolic trough, and an amplitude of a second major systolic peak, a first order linear equation, which may be normalized for body surface area. The data combined may also be used to analyze cardiac output, arterial compliance, and dp/dt.

Title: Eye-tap for electronic newsgathering, documentary video, photojournalism, and personal safety
Inventor: MANN STEVE
IPC: G02B27/01
Filed: 1999-03-15
Abstract: A novel system for a new kind of electronic news gathering and videography is described. In particular, a camera that captures light passing through the center of a lens of an eye of the user is described. Such an electronic newsgathering system allows the eye itself to, in effect, function as a camera. In wearable embodiments of the invention, a journalist wearing the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Moreover, the journalist can easily become part of a human intelligence network, and draw upon the intellectual resources and technical photographic skills of a large community. Because of the journalist's ability to constantly see the world through the apparatus of the invention, which may also function as an image enhancement device, the apparatus behaves as a true extension of the journalist's mind and body, giving rise to a new genre of documentary video. In this way, it functions as a seamless communications medium that uses a reality-based user-interface.

Title: Methods for preparing nucleotide integrases
Inventor: MATSUURA MANABU
IPC: C12N9/22
Filed: 1997-11-18
Abstract: The present invention provides new, improved and easily manipulable methods for making nucleotide integrases. The present method also relates to a nucleotide integrase and an improved method for making RNA-protein complexes for use in preparing nucleotide integrases in vitro. The nucleotide integrase is prepared by introducing a DNA molecule which comprises a group II intron DNA sequence into a host cell. The group II intron DNA sequence is then expressed in the host cell such that RNP particles having nucleotide integrase activity are formed in the cell. Such RNP particles comprise an excised group II intron RNA  encoded by the introduced DNA molecule and a group II intron-encoded protein encoded by the introduced DNA molecule. Thereafter the nucleotide integrase is isolated from the cell. In another embodiment, the nucleotide integrase is prepared by combining in vitro an excised group II intron RNA, hereafter "exogenous RNA", with group II intron-encoded protein. In another embodiment, the nucleotide integrase is prepared by combining "exogenous RNA" with an RNA-protein complex which comprises a group II intron-encoded protein.

Patent CA-2275104-A1 (CA)
Inventor: SRIKANTH RAMAMOORTHY
IPC: A47L15/42
Filed: 1999-06-15
Abstract: A cabinet structure is thermally insulated by placing a first insulation material directly upon a surface of the cabinet structure and then covering the insulation material with a barrier sheet that is affixed along an annular edge portion thereof to the cabinet structure. In this manner, the insulation material is retained within a chamber defined between the barrier sheet and the cabinet structure. This chamber is then evacuated to a low pressure, generally in the order of .1-10 mm Hg, and sealed. This integrated vacuum panel insulation arrangement is particularly advantageous for use in constructing entire thermal cabinets by providing a blank that defines multiple walls of the cabinet; arranging the insulation on the inner surfaces of the blank; placing one or more barrier sheets over the insulation; attaching edges of the barrier sheet(s) to the inner surfaces of the walls so as to define respective chambers between the barrier sheet(s) and the respective inner wall surfaces; evacuating each of the chambers; and sealing the chambers. When used with a cabinet that includes an additional liner, this insulation arrangement is preferably used on the shell of the cabinet and, following insertion of the liner within the shell, additional insulation is provided between the liner and the barrier sheet(s).

Abstract: The particle trap (15) that extends behind an elbow in the air flow stream (6) in a turbo-prop engine is delimited at the back by an end plate (12) to which intake housing suspension rods (10) supporting the front of the rotating shaft (2), are fastened. It is divided by suspension arms (11) which may be drilled (21) to restore the continuity of the annular chamber forming the trap. Therefore the intake housing suspension device extends through the trap. This type of trap makes use of the inertia of solid bodies carried by the air drawn in, and which could damage the engine blades, and to collect them.

Title: Apparatus and method for separating an immiscible liquid from a liquid influent
Inventor: BATTEN WILLIAM C
IPC: B01D17/032
Filed: 1999-07-21
Abstract: An apparatus (10) for the separation of immiscible liquids from liquid influent has a containment vessel (12). An influent channel (14) extends toward the bottom of the vessel so the influent is discharged vertically upward, a downwardly curved deflection plate (20) is mounted above and aligned with the discharge end (18) of the influent channel, and a plate (22) with a downward slope from a central location extends toward the periphery of the vessel in a lower portion of the vessel than the deflection plate. This permits the influent to move radially outwardly thus slowing the influent and providing a residence time for gravitational separation of lighter immiscible liquids from the influent. A gap (24) between the downward slope plate and the discharge end of the influent channel permits gravitational release of trapped immiscible liquids. A transfer tube (32), a sensor (38), and a pump (40) are provided to pump the separated immiscible liquids out to a remote location. A suction conduit suctions heavier-than-water solids from the bottom of the vessel and an effluent channel (16) channels the separated water to a remote location, such as a sewer.
