Title: Use of molecularly imprinted polymers for stereo- and/or regioselective synthesis
Inventor: MOSBACH KLAUS
IPC: C07B53/00
Filed: 1993-12-27
Abstract: Molecularly imprinted polymers can be utilized in stereo- and regio-selective synthesis. These systems can be utilized, e.g. for peptide synthesis, by selectively coordinating reactants at a preformed cavity. Further, such polymers may be used for the selective removal of one enantiomeric species from solution, allowing reaction to be directed to another species in bulk solution leading to stereoselective and/or regioselective synthesis in the cavity of for instance peptides. Additionally, when utilized as regioselectively interacting protectioning matrices, these polymers can direct reaction to an alternate centre of a reacting substrate.

Filed: 1995-06-28
Abstract: A self-cleaning device for filtering air in a harvester includes a venturi ejector connected to a source of pressurized air which, in a cotton harvester, includes the cotton handling system blower.  The ejector includes nozzle, a vacuum chamber shaped to minimize dead air zones and eddy currents, and a diffuser section.  The vacuum chamber is supported near a rotating air inlet screen to vacuum debris from the inlet side of the screen.  The debris is drawn into the negative pressure air stream upstream of the nozzle and is positively directed away from the engine compartment and other components on the harvester.  The engine cooling fan receives only screened air, and the use of a source of air which is independent of the cooling fan, as well as any separate screen cleaning fan, helps to retain maximum engine cooling capacity.

Abstract: A program cartridge 4 is detachably attached to a body device 2. The game cartridge 4 stores a game program and certain data. The body device 2 reads the game program from the game cartridge 4 and executes the game program, and reads the certain data and refers to the data to display OBJ images and BG images provided with parallax in left and right display systems. That is to say, the body device 2 displays in the left and right display systems planar OBJ images having no parallax themselves shifted in the opposite directions in the right and left by the amount corresponding to provided parallax information. Also, the body device 2 cuts out left and right two BG images from a planar source image having no parallax by itself with the two images shifted in the opposite directions in the left and right by the provided parallax amount and displays the cut out left and right BG images at the same positions in the left and right display systems. Furthermore, the body device 2 displays planar BG images having no parallax themselves in the left and right display systems while shifting them by an amount corresponding to the provided parallax information in the left and right opposite directions. This way, an OBJ image and a BG image are displayed with parallax provided by a novel method.
