Methods For Forming Injected Molded Parts And In-Mold Sensors Therefor

Methods For Forming Injected Molded Parts And In-Mold Sensors Therefor

US Patent:
2011010, May 5, 2011
Filed:
Apr 14, 2009
Appl. No.:
12/937639
Inventors:
David Kazmer - North Andover MA, US
Rahul Panchal - Eden Prairie MN, US
Stephen Johnston - Ashville NY, US
Assignee:
UNIVERSITY OF MASSACHUSETTS LOWELL - Lowell MA
International Classification:
B29C 45/76
US Classification:
264 406, 425170
Abstract:
A method for use in forming a molded part includes providing a mold having a cavity and a movable pin, injecting a moldable material into the cavity, biasing the movable pin to maintain an end of the movable pin in contact with the moldable material in the cavity during the curing of the moldable material and until the moldable material is cured, and monitoring movement of the biased movable pin during curing of the moldable material in the mold. Also disclosed is a sensor engageable with an end of a movable pin of a mold for monitoring the forming of a moldable part, and systems employing the same.

Molds For Production Of Ophthalmic Devices

US Patent:
8262952, Sep 11, 2012
Filed:
Oct 31, 2007
Appl. No.:
11/931205
Inventors:
Bruce E. Lawton - Rochester NY, US
Stephen P. Johnston - Ashville NY, US

Sanjay Rastogi - Rochester NY, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
B29D 11/00
US Classification:
264 25
Abstract:
A mold assembly for the manufacture of at least one ophthalmic device used in or on the eye is disclosed. The mold assembly includes a mateable pair of mold parts wherein at least one of the mold parts comprises at least an oxygen-absorbing mold material and an oxygen scavenger composition containing (i) an oxygen scavenging polymer comprising a polymer backbone and one or more substituted or unsubstituted cyclic olefinic groups covalently linked to the polymer backbone; and (ii) an oxygen scavenging catalytic amount of a transition metal catalyst.

Heated Mold Tooling

US Patent:
2010016, Jul 1, 2010
Filed:
Mar 8, 2010
Appl. No.:
12/719641
Inventors:
Bruce E. Lawton - Rochester NY, US
Stephen P. Johnston - Ashville NY, US
Assignee:
BAUSCH & LOMB INCORPORATED - Rochester NY
International Classification:
B29D 11/00, B22D 15/00
US Classification:
264 25, 249164, 249111
Abstract:
A method for varying a radius of an optical quality surface of a casting mold formed in a tooling cavity, the tooling cavity at least partially defined by an optical tool having an optical quality surface of a given radius, includes imparting a compressive stress within the optical quality surface of the casting mold to predictably decrease the radius of the optical quality surface of the casting mold.
