Title: Method for making stable, extracellular tyrosinase and synthesis of polyphenolic polymers therefrom
Inventor: DELLA-CIOPPA GUY RICHARD
IPC: C12N9/02
Filed: 1993-11-22
Granted: 2000-08-08
Abstract: A process for the in vitro production of chemically modified polyphenolic polymer (PPP). First, stable, highly active extracellular tyrosinase is produced from genetically transformed microorganism such as Srrepromyces antibioticus. The tyrosinase is then incubated with a reaction substrate such as 1-tyrosine, hydrolyzed protein, or an oligopeptidc in combination with 1-tyrosine. The ratio of the oligopeptide/tyrosine combination as well as variation in the concentration of tyrosinase can be used to modify the color, the molecular size, and the spectral absorbance properties of the PPP produced.  Alternatively, or additionally, oxidants such as hydrogen peroxide or hypachlorite can be used to modify the color of the PPP, regardless of the method used to produce the PPP, and the PPP can subsequently be fractionated using molecular weight cut-off ultrafiltration. Organic solvents can also be used in the method of making PPP to produce PPPs having variable but reproducible physical properties.

Patent CA-2154820-C (CA)

Granted: 2005-02-22
Abstract: This invention pertains to methods and apparatus for processing workpieces, including effecting changes in the workpieces by applying ultrasonic energy to the workpieces using novel apparatus and steps for applying the ultrasonic energy to the workpieces. Specifically, an ultrasonic horn and anvil are used to apply ultrasonic energy in a limited amount, to effect change such as cutting in one layer of a workpiece without effecting a corresponding change in the other layers of the workpiece, although some change in the other layers may be tolerated and/or desired. A rotary horn and anvil are taught, with a protuberance on either the horn or the anvil. In use, the horn and anvil preferably rotate cooperatively in close proximity to each other at a nip, and apply pressure and corresponding ultrasonic energy to the workpiece only when the protuberance rotates into the nip, even though ultrasonic energy may be applied uniformly to the ultrasonic horn throughout the rotation of the protuberance. The workpieces may be presented to the horn/anvil combination as contained serially in a web of workpieces passing through the gap at a given speed; the speed of the protuberance being preferably substantially matched to the speed of the web while the protuberance is applying ultrasonic energy to a workpiece, but may differ from the speed of the web when the protuberance is not applying ultrasonic energy to a workpiece.

Abstract: An occlusive implant includes an elongated member having an end, a portion proximal to that end, and a portion distal to that end. The proximal portion is sufficiently flexible so that it can be folded upon itself and maintain that configuration without further restraint. At least a portion of the distal portion is preformed to have a first configuration when in a first state and a second configuration when in a second state. The distal portion second configuration has a flow resistance substantially greater than that of the proximal portion.

Inventor: BILAK ROMAN A
IPC: B09B1/00
Filed: 1996-09-11
Granted: 2000-05-30
Abstract: The invention is an apparatus and method for injection of wastes in slurry form within an underground formation. The method consists of: identifying a suitable target stratum; calculating the approximate total available storage volume of the target strata; injecting a slurry of waste materials into a well in a series of injection episodes separated by interinjection periods; measuring the well bottom pressure of the slurried wastes during each injection episode and interinjection period; and terminating the injection process when the target strata is saturated with slurried wastes. An injection episode is terminated when the well bottom pressure begins to climb substantially above the steady state level, and an interinjection period is terminated when the well-bottom pressure drops below a fixed level. Surface uplift indicators, microseismic measuring and well-bottom pressure within monitoring wells may be used to assess the distribution and movement of embedded solids both during and after the injection process. The apparatus comprises means to produce and inject an appropriate slurry and monitor the entombed slurry during and after the injection process.
