Publication number: 20170176606Abstract: A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. In the method and apparatus, a polymer matrix of a transparent polymer and nanoparticle scintillators is placed on top of a collimated bundle having a plurality of capillaries and pressed in a pressure vessel until the polymer matrix is forced into the capillaries. Pressure is applied via an anvil on top of the polymer matrix. To prevent fracturing of the collimated bundle during pressing, back pressure is supplied to the pressure vessel via a valve, which controls a supply of high pressure gas. Alternatively, the back pressure may also be supplied by a press (and or pressure) and support to the collimated bundle is provided by a high melting point thermoplastic. Heat may be applied to the polymer matrix via the anvil to speed the pressing operation due to the viscosity of the polymer.Type: ApplicationFiled: March 3, 2017Publication date: June 22, 2017Inventors: Theodore F. Morse, Rajiv Gupta, Avilash Cramer, Christopher Bull, Paul Waltz

Patent number: 5102792Abstract: L-Serine derivatives produced by the enzyme catalyzed aldol condensation of glycine and an aldehyde in aqueous solution are recovered in high yield by extracting the aqueous product solution containing said serine derivatives with an organic phase comprising (i) an aldehyde, or (ii) mixtures of an aldehyde and a water immiscible organic solvent, followed by re-extracting the organic phase with an aqueous phase having a pH of less than about 7.0. The L-erythro isomers of L-serine derivatives such as L-phenylserine may be preferentially prepared by the use of this extraction/re-extraction procedure in combination with bioreactor reaction conditions which include a pH of from about 7.5 to 10, an aldehyde concentration of from about 1 to about 90 grams/liter, a glycine concentration of from about 10 to about 300 grams/liter, and a molar ratio of glycine to aldehyde of from about 4:1 to about 100:1.Type: GrantFiled: August 13, 1987Date of Patent: April 7, 1992Assignee: W.
