Title: Method and apparatus for destruction of volatile organic compound flows of varying concentration
Inventor: MARTIN RICHARD J
IPC: B01J8/02
Filed: 1995-11-29
Abstract: Apparatuses and methods for treating gas streams containing variations in VOC concentration whereby the VOC's are destroyed in a combination non-catalytic/catalytic oxidation system (33) are disclosed. A non-catalytic destruction matrix (12) composed of inert ceramic materials (14) that enhance process mixing and provide thermal inertia for process stability is used when VOC concentrations are high and a catalytic oxidizer (36) is principally used when VOC concentrations are low. The exhaust from the non-catalytic destruction matrix (12) is passed through the catalytic oxidizer (36) to maintain proper catalytic oxidizer temperatures. Supplemental fuel and air are added as appropriate upstream or downstream of the non-catalytic oxidizer (10) to maintain proper heat values in each portion of the system.

Title: Light fixture with controllable light block
Inventor: DISANTO DOROTHY K
IPC: F21V29/00
Filed: 1996-04-17
Abstract: A lighting fixture (10) with a controllable light block (26). The fixture (10) includes a reflector (16) and high intensity discharge lamp (18) that requires a re-strike or warm-up period to come to full brightness or intensity. A cover member (26) is mounted to the reflector (16) and is moveable between an unblocked position and a blocked position. Movement of the cover member (26) is immediate so that blockage of light from the fixture is immediately effectuated. The apparatus is configured so that cover member (26) can be in the blocked position for indefinite periods of time even though the arc lamp continues to be operated at full power, without heat buildup which is detrimental to any part of the apparatus. The cover member (26) also allows light control and special effects lighting options. Another aspect of the invention utilizes an aperture (66) in the cover member (26) that is alignable with the light source when the cover member (26) is in the blocked position.  Different inserts (78A, 135, 77) can be placed in the aperture, or it can be opened and closed independently to create special or theatrical effects including changes in color.

Title: Naphtha upgrading process
Inventor: BOYD SHERRI LYNNE
IPC: C10G35/095
Filed: 1996-02-14
Abstract: Low sulfur gasoline of relatively high octane number is produced from a thermally cracked sulfur-containing naphtha such as coker naphtha, by hydrodesulfurization followed by treatment over an acidic catalyst, preferably a zeolite such as ZSM-5 or zeolite beta with a hydrogenation component, preferably molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product.

Abstract: An optical chamber for use in a laser or other optical device includes a hollow container with holes at opposite ends.  A fixed mirror is sealed to the housing and overlies one hole, whereas a movable mirror is sealed to the housing by a flexible seal such as and O-ring interposed between the mirror and the housing. A variable force actuator such as a piezoelectric element biases the movable mirror against the seal.  By varying the force applied by the actuator, the movable mirror can be moved towards and away from the fixed mirror to vary the path length through the chamber. The chamber can provide a low cost tunable gas laser.

Title: Enzyme additives for ruminant feeds
Inventor: SEWALT VINCENT J H
IPC: A23K1/165
Filed: 1996-07-05
Abstract: Fibrolytic enzyme supplements for increasing the digestibility of legume forages and grain feeds for ruminants, a method of treating legume forages and grain feeds with fibrolytic enzymes, and feed compositions consisting of feed materials treated with a mixture of fibrolytic enzymes are provided. The enzyme supplements do not pre-digest the feed material but assist in the colonization of feed particles in the rumen by ruminal microbes. The fibrolytic enzyme supplements consist of mixtures of cellulase and xylanase in certain preferred ratios and levels which are dependent on the feed material to be treated. The cellulase and xylanase are dissolved in a buffer solution and sprayed onto dry legume forages or grain feeds. The feed material is then incubated for at least three hours to allow the enzymes to be absorbed into and adhere to the feed material. The resulting feed compositions remain stable for at least one year against pre-digestion. When cellulase and xylanase are applied to legume forages and grain feeds in certain ratios, levels and in accordance with the methods of the present invention, synergistic effects between the enzymes occur, providing large improvements in digestibility of feed materials at low enzyme levels.

Abstract: A calibration network (110-130, 180, 182) for pro-viding weighting factors for a beam pattern of an adaptive array of antenna elements (86) of a communication device (70) is self calibrated by modulating and demodulating a narrowband channel with a common broadband signal con-taining a pseudo-random number sequence (PRNS) having a relatively short pulse rate per bit and a power level rel-atively low to that of a noise threshold of the narrowband signal channel. Errors introduced into the PRNS by a se-lected complementary one of a reception (116) and trans-mission (114) path are determined by calculating a process-ing gain for the calibration network based upon the errors introduced into the PRNS. Then, by applying a conver-gence algorithm (130) to resolve amplitude and phase vari-ations introduced by components (112-118) in the selected path, these amplitude and phase variations are mitigated against by the communication device (70) of the figure by subsequently determining and applying a correction factor (126) appropriate to compensate for these variations.

Patent CA-2231733-A1 (CA)
Inventor: ZOU HEHONG
IPC: G05B13/04
Filed: 1997-07-11
Abstract: A process control system (100) controls a non-self regulating process through a control output signal (u(t)) based on a set point YSET and a measured process variable (y(t)). The process control system includes a control circuit (102, 104, 106, 108) having a set point input, a process variable input and a control output. The control circuit generates the control output signal (u(t)) on the control output as a function of the set point YSET received on the set point input and the measured process variable (y(t)) received on the process variable input. An auto-tuning circuit (106) excites the process, estimates a process model based on an intersection between rising and falling asymptotes of the measured process variable (y(t)), and then tunes the control function to the process (110) based on the process model. The auto-tuning circuit obtains robust results, but is computationally simple such that the circuit can be implemented with hardware or software in low-power and low-memory applications, such as in field-mounted controllers.

Patent CA-2238075-A1 (CA)
Inventor: HAYDEN MICHAEL R
IPC: A61K38/00
Filed: 1996-11-15
Abstract: A protein, designated as HIP1, interacts differently with the gene product of a normal (16 CAG repeat) and an expanded ( 44 CAG repeat) HD gene. The HIP1 protein originally isolated from the yeast two-hybrid screen is encoded by a 1.2 kb cDNA, devoid of stop codons, that is expressed as a 400 amino acid polypeptide. By further screening of a human frontal cortex cDNA library, and employing the protocol for 5' Rapid Amplification of cDNA ends (RACE), a total of 4795 nucleotides (with an open reading frame of 914 amino acids) of the 10 kb message HIP1 have been isolated to date. Expression of the HIP1 protein was found to be limited to the brain, where the interaction of the HIP1 with the HD protein appears to be necessary for the association of the HD protein with the membrane or specific cytoskeletal components to render it functional.  Because HIP1 interacts with expanded HD protein less well than with normal length HD, introduction of additional HIP1 or overexpression of HIP-1 can lead to increased functionality of the defective or normal HD protein.  Alternatively, modified forms of the HIP1 which bind more effectively to expanded HD could be introduced to convert the expanded HD protein into a functional molecule.
