Title: Method and apparatus for compensating for solar torque transients on a satellite during a solar eclipse
Inventor: BENDER DOUGLAS J
IPC: B64G1/24
Filed: 1992-10-15
Abstract: METHOD AND APPARATUS FOR COMPENSATING FOR SOLAR TORQUE      TRANSIENTS ON A SATELLITE DURING A SOLAR ECLIPSE                 ABSTRACT OF THE DISCLOSURE This invention discloses a method for determining when an orbiting satellite (10) is eclipsed from the sun in order to remove control torques to the satellite (10) which compensate for the disturbance of solar pressure on the satellite (10). A current measuring device (46) measures the current traveling through a particular circuit associated with the satellite (10) which is indicative of the satellite batteries being discharged, as would occur during an eclipse. The measured current is applied to a threshold logic circuit (48) which sends a signal to a control compensator (36) if the measured current exceeds a predetermined threshold level. Consequently, the compensation provided by the control compensator (36) removes the compensation for compensating for solar pressure when the satellite (10) is in an eclipse. In a second implementation, the threshold logic circuit (48) is replaced with a proportionality logic circuit to compensate for the effects of partial eclipses.

Title: Optical time domain reflectometry measurements on a multi-branch optical network
Inventor: GRIMES GARY J
IPC: H04B10/071
Filed: 1993-09-30
Abstract: OPTICAL TIME DOMAIN REFLECTOMETRY MEASUREMENTS ON A MULTI-BRANCH OPTICAL NETWORK Abstract Detecting and evaluating optical subcircuits created by optical splitters in an optical circuit. One or more optical wavelengths are utilized for the transmission of data; whereas, other optical wavelengths are utilized to performoptical time domain reflectometry measurements on each optical subcircuit. Following an optical splitter, each optical path from the optical splitter has inserted into it an optical filter which allows the transmission of the optical wavelengths utilized for data transmission and one of the optical wavelengths utilized to perform the optical time domain reflectometry measurements. An optical time domain reflectometry instrument transmits each of the optical wavelengths, utilized fortesting, individually into the optical circuit and analyzes the returned optical pulse. Since only one optical subcircuit allows the passage of any given optical wavelength for testing, each optical subcircuit can be fully analyzed.
Patent CA-2108876-A1 (CA)
Title: Vacuum Cleaner with Illuminated Belt View
Inventor: SEPKE ARNOLD L
IPC: A47L9/30
Filed: 1993-10-20
Abstract: An illuminated belt view for a vacuum cleaner wherein light is transmitted, via a light pipe, from a remote light source to an area directly underneath a transparent belt view window.  The transparent belt view window is formed in the vacuum cleaner hood to allow the operator to observe the operating condition of the belt therein, the belt being operable to transfer rotational motion from a motor output shaft to a rotary brush.  Illumination of the belt in the area of the belt view window allows the belt and the operating condition thereof to be observed during low ambient light conditions.  Use of light from the light source, which is primarily a headlight, removes the need for an independent light source for the belt view window without significantly decreasing the amount of light which is transmitted to the area in front of the machine.  Also, use of a single light source for indicator illumination and headlight functions reduces the energy necessary to operate the vacuum cleaner, the heat produced by the vacuum cleaner, and manufacturing and maintenance costs by minimizing the number of light bulbs to be installed and replaced.

Such rolling mediators are, for example, selectins and selectin ligands which have binding partners expressed on leukocytes. In another specific embodiment, for modelling leukocyte rolling followed by adhesion/arrest, the apparatus of the invention comprises a solid phase surface with both rolling mediators and integrin binding partners present thereon. The apparatuses of the invention can be used for collecting, concentrating, purifying, and analyzing blood and blood components, in particular, leukocytes and subsets thereof.  The invention further relates to methods for identifying inhibitors or, alternatively, promoters (agonists, functional components) of the inflammatory response. Therapeutic and diagnostic methods, pharmaceutical compositions and kits are also provided.

Inventor: DAO KIM
IPC: F25B15/02
Filed: 1993-04-05
Abstract: A regenerative absorption cycle using a super-pressure boiler to achieve a high coefficient of performance. An ammonia/water solution is boiled in high-pressure boiling conduit (66). Boiled-off high-pressure ammonia vapor is condensed (96), expanded to low-pressure (99), and boiled in evaporator (101) to extract heat from a refrigerating fluid going to cooling load (104). Low-pressure ammonia vapore from evaporator (101) returns to regenerator (28) and is absorbed back into low-pressure liquid. The low-pressure solution from regenerator (32) is then cooled in absorber (56) to reject heat from the cycle and is then pumped (58) back to the high-pressure boiling conduit (66). The liquid solution from high-pressure boiling conduit (66) is pumped up to an externally-heated super-pressure boiler (11). Ammonia vapor from boiler (11) is absorbed back into super-pressure liquid in conduit (26), which functions as an internal heat source to heat the high-pressure boiling conduit (66). Solution from conduit (26) is expanded (36) to boil in high-pressure conduit (38).
