Us Patents

5-Substituted-2-(4-Cyanophenyl)-1,3-Dioxanes

US Patent:
4335012, Jun 15, 1982
Filed:
Jul 6, 1981
Appl. No.:
6/280762
Inventors:
Howard Sorkin - Berkeley Heights NJ
Assignee:
Timex Corporation - Waterbury CT
International Classification:
C09K 334
C02F 113
US Classification:
25229961
Abstract:
Compounds of the formula: ##STR1## wherein R is an alkyl, alkoxy, aryl, aryloxy, arylester, carboxy or ester derived from carboxy are used as liquid crystal materials in electro-optical displays. A typical embodiment is 5-butyl-2-(4-cyanophenyl)-1,3-dioxane which has a very low threshold voltage in nematic displays. On rubbed indium oxide surfaces the threshold voltage was 0. 6 V using predominately the trans isomer. It was nematic over the range 32. 2. degree. C. to 34. 6. degree. C.

Liquid Crystal Devices

US Patent:
4003844, Jan 18, 1977
Filed:
Nov 17, 1975
Appl. No.:
5/632815
Inventors:
Howard Sorkin - Berkeley Heights NJ
Assignee:
RCA Corporation - New York NY
International Classification:
C09K 334
G02F 113
US Classification:
252299
Abstract:
The addition of certain nitrobenzene compounds to liquid crystal compositions having positive dielectric anisotropy, lowers the threshold voltage of electro-optic cells including such compositions. The nitrobenzene compounds have the formula ##STR1## wherein R is an alkyl group of 1-20 carbon atoms, X. sub. 1 and X. sub. 3 can be hydrogen or nitro and X. sub. 2 can be hydrogen, --NO. sub. 2, ##STR2## or--O--CH. sub. 2 CN, with the proviso that at least one of X. sub. 1, X. sub. 2 or X. sub. 3 is a radical other than hydrogen.

Process For Coating Inorganic Particles With Condensating Polymers

US Patent:
4594271, Jun 10, 1986
Filed:
Oct 15, 1985
Appl. No.:
6/787408
Inventors:
Pieter C. Scholten - Waalre, NL
Fred W. Snyder - Eindhoven, NL
Howard Sorkin - Glen Ridge NJ
Assignee:
U.S. Philips Corporation - New York NY
North American Philips Corporation - New York NY
International Classification:
B05D 700
US Classification:
427221
Abstract:
A first stable suspension of at least one solid monomer, capable of being polymerized to a condensation polymer when heated, is formed in a first organic liquid inert during polymerization and containing a minor amount of a dispersing agent stable during said polymerization. A second stable suspension of finely divided inorganic particles in a second organic liquid inert during said polymerization and miscible with said first organic liquid, is formed and contains a minor amount of a dispersing agent. The first suspension is then added to the second suspension while stirring and heating the second suspension to the polymerization temperature of the monomer.

Process For Filling Dynamic Scattering Liquid Crystal Cells

US Patent:
4091847, May 30, 1978
Filed:
Nov 22, 1976
Appl. No.:
5/744127
Inventors:
Howard Sorkin - Berkeley Heights NJ
Assignee:
RCA Corporation - New York NY
International Classification:
G02F 113
C09K 334
B65B 3104
US Classification:
141 7
Abstract:
A dynamic scattering liquid crystal cell is filled from a single fill port by first applying a film of a mixture of at least two resistivity dopants, each having different ions, to the cell walls, then filling the cell with a liquid crystal composition containing both dopants.
