US Patent:

20040266921, Dec 30, 2004

Filed:

Jun 26, 2003

Appl. No.:

10/606420

Inventors:

Klein Rodrigues - Signal Mountain TN, US
Yves Smet - Denderhoutem, BE
Stacey Elliott - Philadelphia PA, US

International Classification:

C08L001/00

US Classification:

524/211000, 524/236000

Abstract:

The present invention relates to the use of (hydroxyalkyl)urea and (hydroxyalkyl)amide in aqueous-based polymer compositions to maintain hydration of said composition. Maintenance of hydration improves properties such as freeze/thaw stability, stability of the polymer composition, retardation of evaporation from the composition, and retardation of evaporation from wetted articles containing said polymer composition.

Appl. No.:

17/741350

Inventors:

- San Ramon CA, US
Stacey Lynn ELLIOTT - Pleasanton CA, US

International Classification:

G01N 11/08

Abstract:

A viscometer includes a viscosity sensor with a liquid flow channel for measuring a viscosity of a liquid flowing through the liquid flow channel, a manifold with an inlet and an outlet for receiving a liquid sample through the inlet of the manifold and providing the received liquid sample through the outlet of the manifold to the viscosity sensor, and a pump coupled with the manifold for causing an in-flow of the liquid sample into the manifold through the inlet of the manifold and an out-flow of the received liquid sample from the manifold through the outlet of the manifold. Also disclosed is a viscosity sensor module with two or more viscosity sensors.

International Classification:

B29D 11/00
B29C 37/00
B29C 39/36
B29C 43/50

Abstract:

The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; bring a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.
