Abstract: A process is disclosed for the extraction, production and purification of carbon dioxide gas. The process may also be employed for the production of aqueous and/or organic solutions of bicarbonate ions using a precursor feed stream of gas containing carbon dioxide. The process consists of the countercurrent flushing of a packed tower-type bioreactor with gas containin g carbon dioxide and a liquid solvent. The bioreactor contains carbonic anhydrase covalently bound to an inert inorganic support. The carbon dioxide of the gaseous phase diffuses into the liquid phase. The immobilized carbonic anhydrase catalyses the hydration of the carbon dioxide which forms hydrogen and bicarbonate ions. The solution of ions may be employed directly or, alternatively, subjected to an ion-exchange resin to immobilize the bicarbonate ions. The aqueous solution of hydrogen and bicarbonate ions may also be recirculated into a second identical bioreactor, wherein they are catalytically converted to water and carbon dioxide.

Abstract: Oleamide is an endogenous fatty acid primary amide that possesses sleep- inducing properties in animals and has been shown to effect seratonergic systems and block gap junction communication in a structurally specific manner. Certain agents can serve both as an oleamide agonist and as an inhibitor of fatty acid amide hydrolase. Fatty acid amide hydrolase is responsible for the rapid inactivation of oleamide in vivo. The structural features of oleamide required for inhibition of gap junction-mediated chemical and electrical transmission in rat glial cells are defined. Effective inhibitors fall into two classes of fatty acid primary amides of which oleamide and arachidonamide are the prototypical members. Of these two, oleamide constitutes the most effective and its structural requirements for inhibition of the gap junction are well defined. It requires a chain length of 16-24 carbons of which 16-18 carbons appears optimal, a polarized terminal carbonyl group capable of accepting but not necessarily donating a hydrogen bond, a .DELTA. 9 cis double bond, and a hydrophobic methyl terminus. Within these constraints, a range of modifications are possible, many of which may with enhanced in vivo properties.

Title: Focus control for search lights
Inventor: FRICKE KENNETH J
IPC: F21Y101/00
Filed: 2000-12-29
Granted: 2005-03-29
Abstract: The focus angle .theta. of a search light (12) mounted on a helicopter (10) or other platform (10) is narrowed or widened by rotating a bidirectional focus control cam (42) in a clockwise or counterclockwise direction as selected by a manually operated three-position control switch (SW1) which determines the rotational direction of a DC motor (28) driving the bidirectional focus control cam (42). The DC motor (28) has first and second terminals (92, 93) which are selectively connected to either a DC power source (72) or ground (73) by a double-pole, single throw dual relay (60) which reverses the polarity and thus the direction of rotation of the DC motor (28). The dual relay (60) is connected by the same single wire interface (32) to the manually operated control switch (SW1), which manually operated control switch (SW1) is within a control box (62) located in the helicopter (10). By operating the manually operated control switch (SW1) to connect coils (76,78) in the dual relay (60) to either a power source (72) or to ground (73), the coils (76,78) are selectively energized or deenergized causing the dual relay (60) to operate switches (SWR, SW3) that reverse polarity of current flowing through the DC motor (28). This selectively changes the direction of rotation of the bidirectional cam (42) which advances and retracts a focusing reflector (47) within the search light (12) to widen and narrow its focus angle .theta., thereby widening and narrowing the area (16) illuminated by the search light beam (14).

Abstract: In order to optimize the flux or flow of carbon intermediates from normal cellular metabolism into PHAs it is desirable to optimize the expression of the enzymes of the PHA biosynthetic pathway. Gene fusions are genetic constructs where two open reading frames have been fused into one and encode hybrid proteins and in some cases bifunctional hybrid enzymes. Linkers may be added to spatially separate the two domains of the hybrid protein. In the case of enzymes which catalyse successive reactions in a pathway, the fusion of two genes results in bringing two enzymatic activities into close proximity to each other. When the product of the first reaction is a substrate for the second one, this new configuration of active sites may result in a faster transfer of the product of the first reaction to the second active site with a potential for increasing the flux through the pathway.

Title: High performance debugging in a message flow environment
Inventor: O'FARRELL WILLIAM G
IPC: G06F11/36
Filed: 2001-04-27
Granted: 2005-05-03
Abstract: A message flow environment permits a developer to define a debug session in which nodes in a defined message flow have a debug function. A debug controller is used to select nodes as breakpoints using data in shared memory accessible to the nodes in the defined message flow. Each node having a debug function will determine whether it is a breakpoint by accessing the shared memory. Where a node determines that it is a breakpoint, the node will communicate debug information to the debug controller. An independent daemon runs to permit a developer to define breakpoints from the set of debug nodes. The nodes having a debug function maintain a stack in the shared memory which is sent to the debug controller by each breakpoint node when reached by a message.
