Patent number: 7927854Abstract: An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in the ratio of peracetic acid formation to peracetic acid hydrolysis specific activities (PAAF/PAAH ratio). The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.Type: GrantFiled: December 7, 2009Date of Patent: April 19, 2011Assignee: E.

The gap defines an impedance Zg to a flow of fluid from the precursor delivery channel. A flow restrictor is disposed within the precursor delivery channel that presents a predetermined impedance Zfc to the flow therethrough. The restrictor is sized such that the impedance Zfc is at least five (5) times, and more preferably at least fifteen (15) times, the impedance Zg. The impedance Zfc has a friction factor f.Type: ApplicationFiled: December 16, 2010Publication date: April 14, 2011Applicant: E. I.

Patent number: 7921673Abstract: An apparatus for measuring the weight of a preform for optical fibers during a chemical deposition process for the formation of a preform is disclosed. The apparatus has at least one elastic constraint associated with at least one end portion of an elongated element made of a chemical deposition substrate for the formation of the preform, a device for inducing an oscillation, for example axial, on said elongated element, a device for detecting the frequency of oscillation of said elongated element, and a device for calculating the weight of the preform according to the detected frequency of oscillation. Advantageously, the device allows the realisation of a method for measuring the weight of the preform wherein the errors in measurement caused by thermal drift effects, by the axial distribution of the masses on the preform and by loads which are different from the mass of the preform in formation are reduced to below the required precision in measurement.Type: GrantFiled: July 31, 2002Date of Patent: April 12, 2011Assignee: Prysmian Cavi E Sistemi Energia S.R.L.Inventors: Marco Ruzzier, Andrea Demergazzi, Davide Sarchi
