Nonreversible Freeze-Thaw Indicator

View page
US Patent:
41487486, Apr 10, 1979
Filed:
Feb 22, 1977
Appl. No.:
5/771049
Inventors:
Robert G. Hanlon - Indianapolis IN
Joe A. Craig - Speedway IN
Leigh B. Bangs - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C09K 300
US Classification:
252408
Abstract:
A nonreversible freeze-thaw indicator which will detect whether an article has been subjected to freezing or thawing conditions comprising an encapsulated translucent to opaque colloidal dispersion of organic solid particles suspended in a liquid medium, said colloidal dispersion having the property of becoming nonreversibly destablized upon freezing which thereafter provides a telltale visual sign if said dispersion rises through its freeze-thaw temperature. After the colloidal dispersion has once been frozen to trigger its irreversible destabilization and is again thawed, it coagulates to form a non-flowing waxy gel, flocculates and precipitates leaving a clear liquid and a coagulated solids layer or partially flocculates to transform a translucent dispersion to a substantially opaque dispersion.

US Patent:
58799184, Mar 9, 1999
Filed:
Nov 24, 1993
Appl. No.:
8/157940

Assignee:
Pioneer Hi-Bred International, Inc. - Des Moines IA
International Classification:
C12N 1500
US Classification:
4351723
Abstract:
An improvement in the process of transporting biological materials into living cells by bombarding the cells with microprojectile particles coated with biological material. In the improved process prior to coating of the particles such as tungsten beads for example, with biological material such as DNA, the particles are first pretreated with a strong inorganic acid such as nitric acid.
