Filed:

Dec 26, 2000

Appl. No.:

09/748427

Inventors:

Robert Burroughs - Doylestown PA, US
William Rowe - Middletown NJ, US

International Classification:

H04N007/173

US Classification:

725/111000, 725/112000

Abstract:

Cable modems and CMTS modules, connected to a single cable so as to provide cable modem service to a respective set of the cable modems, are arranged so one of the CMTSs can backup the other. Each of the CMTSs simultaneously broadcasts its downstream channel on its own assigned one of the cable channels that is accessible by the cable modems for which it is assigned to provide the primary downstream channel, and each cable modem is assigned in addition to its primary downstream channel at least one alternative downstream channel which is supplied by a CMTS other than its primary CMTS, so that when the primary downstream channel of a cable modem becomes invalid the cable modem switches to the alternative downstream channel. When doing so, the cable modem employs many of the parameters that were established during the initialization it performed with the primary CMTS.

Appl. No.:

7/168204

Inventors:

William Rowe - Califon NJ
Shashikant Saraiya - Parlin NJ
Ajay Shah - Elizabeth NJ

Assignee:

Polychrome Corporation - Yonkers NY

International Classification:

C08F 812

US Classification:

525355

Abstract:

A process for preparing polyvinyl phosphonic acid by the steps of polymerizing bis(2-chloroethyl) vinyl phosphonate in the presence of a free radical initiator or catalyst, such as dicumyl peroxide. The resulting poly bis(2-chloroethyl) vinyl phosphonate is then subjected to acid hydrolysis to obtain high purity polyvinyl phosphonic acid having measurable and controllable molecular weight distribution.

Appl. No.:

6/717988

Inventors:

William Rowe - Califon NJ
Thomas Dooley - Teaneck NJ

Assignee:

Polychrome Corp. - Yonkers NY

International Classification:

G03C 154
C07C 3522
C07C11300

US Classification:

430165

Abstract:

Quinone diazide derivatives of adamantane, and especially quinone diazide derivatives of 1,3-dialkyl-5,7-bis(hydroyphenol) adamantanes, have been found to provide unique properties when coated on metal substrate in the preparation of both positive and negative working lithographic plates. The improved lithographic plates are characterized by enhanced speed, coating oleophilicity, alkali resistance, developer latitude and development speed.

International Classification:

C07D25124

US Classification:

544216

Abstract:

An improved method for the preparation of chromophore-substituted vinyl-halomethyl-s-triazines especially 2-(p-methoxystyryl)-4,6-bis-(trichloromethyl)-s-triazine. In the known preparation of these compounds, a two step procedure is utilized wherein an intermediate reaction product has to be isolated. This step of separating the intermediate is eliminated in the present process by dissolving the crude reaction product obtained in the first step in toluene, removing excess hydrogen chloride gas and catalysts by purging the reaction product solution with an inert gas, and then reacting p-anisaldehyde with the toluene solution of the reaction product mixture using piperidinium acetate catalyst to obtain 2-(p-methoxystyryl)-4,6-bis-(trichloromethyl)-s-triazine. As a further improvement of the art the Knoevenagel-type condensation is run until no further water is evolved. At this point the product formed is isolated by filtration and a like amount of catalyst as a second charge is added.
