Title: Fiberoptic display for a video image
Inventor: COSTELLO JAMES G
IPC: A61B5/055
Filed: 1989-12-05
Abstract: ABSTRACT OF THE DISCLOSURE       A coherent fiberoptic display (9) for a region having strong magnetic field comprises transfer optics (2) which launch the image into one end of a coherent fiberoptic bundle (3) that transfers the image from (1) to a fiberoptic bundle (3) that transfers the image from (1) to a fiberoptic display (9).  The image from (1) is viewed on the expanded end (9) of a fiberoptic taper (8).  The image can comprise a video image formed by a CRT (1) located in a region of low magnetic flux density (5) and the fiberoptic taper (8) can be positioned in the imaging zone of a Magnetic Resonance Imaging (MRI) apparatus (10).  The video image can allow the patient (11) to watch television during magnetic resonance imaging.  This distraction will reduce the anxiety experienced during magnetic resonance so that the patient is less apt to move and the magnetic resonance images are less apt to be blurred or destroyed.  The efficiency of magnetic resonance imaging is thus improved.

Abstract: ABSTRACT OF THE DISCLOSURE      An aspheric mirror, for example in the form of an off-axis parabolic mirror or a toric mirror, that includes a first element having a  front surface which defines  a spherical reflector and a spaced apart rear surface.  The spherical  reflector  includes  a  constant  radius  of curvature, an X-axis with an X-axis radius of curvature and a Y-axis with a Y-axis radius of curvature. The first element possesses a first rigidity factor.   A second element includes a front surface sized to mate with the rear surface of the first element along an interface zone.

IPC: G01P3/36
Filed: 1990-10-30
Abstract: ABSTRACT OF THE DISCLOSURE        In a fiber optic gyro of a zero serrodyne system employing a linear ramp voltage, a phase difference is provided, by a rectangular biasing voltage of a fixed period, between two rays of light which propagate through an optical fiber coil in opposite directions. Interference light of the two rays of light is detected and the detected output is synchronously detected by the biasing voltage in a synchronous detector.  A positive increment and a negative increment in the synchronously detected output are detected by a positive increment detector and a negative increment detector, respectively. The positive and negative increments thus detected are added together by an adder, and based on the added output, a ramp voltage generator is controlled so that a maximum ramp phase shift which is applied to the two rays of light may be an integral multiple of 2 .pi.rad.

Title: Apparatus and method for reducing nox emissions
Inventor: BREEN BERNARD P
IPC: F23J15/00
Filed: 1991-02-19
Abstract: Apparatus and method for reducing NOX emissions from furnace flue gas are provided in which a stream of natural gas or other fluid fuel which has little or no fixed nitrogen is introduced into the upper portion of the furnace.  The fuel stream has sufficient turbulence to form eddies surrounded by the flue gas so that the fuel reacts with the nitrogen oxides in the flue gas to form ammonia-like and cyanide-like compounds and nitrogen gas.  The ammonia-like and cyanide-like compounds react with additional amounts of nitrogen oxides in the flue gas to form nitrogen gas, water vapor and carbon dioxide. In this manner, the amount of nitrogen oxides in the flue gas is reduced.  The invention can be easily applied to new furnaces or retrofitted on existing furnaces.
