Filed:

Feb 1, 2001

Appl. No.:

09/775361

Inventors:

Wen Sen Li - Holmdel NJ
John E. Thornton - Newtown PA
Zhenrong Guo - East Brunswick NJ
Shankar Swaminathan - Monmouth Junction NJ

Assignee:

Bristol-Myers Squibb Company - Princeton NJ

International Classification:

C07D49100

US Classification:

540462, 548181

Abstract:

The present invention relates to a process for the preparation of epothilone analogs by initially forming novel ring-opened epothilones and carrying out a macrolactamization reaction thereon. The subject process is amenable to being carried out in a single reaction vessel without isolation of the intermediate compound and provides at least about a three-fold increase in yield over prior processes for preparing the desired epothilone analogs.

International Classification:

F23D 1136

US Classification:

431153, 431255

Abstract:

A dual-action safety arrangement for a piezoelectric lighter includes an axle holder provided at an inner side of a casing and an ignition cap, which is slidably mounted on a ceiling of the casing in a radially movable manner about an operation axle held at the axle holder, including a depressing arm extended to rest on top of a piezoelectric unit. To ignite the piezoelectric lighter, the ignition cap must be radially and rearwardly slid to actuate a gas emitting nozzle for releasing the gas from a liquefied gas storage and simultaneously depressed to depress a movable operating part of the piezoelectric unit to generate sparks to ignite the gas emitted from the gas emitting nozzle so as to ignite the piezoelectric lighter.

Abstract:

Compositions for hydrogen storage and methods of making such compositions employ an alloy that exhibits reversible formation/deformation of BH anions. The composition includes a ternary alloy including magnesium, boron and a metal and a metal hydride. The ternary alloy and the metal hydride are present in an amount sufficient to render the composition capable of hydrogen storage. The molar ratio of the metal to magnesium and boron in the alloy is such that the alloy exhibits reversible formation/deformation of BH anions. The hydrogen storage composition is prepared by combining magnesium, boron and a metal to prepare a ternary alloy and combining the ternary alloy with a metal hydride to form the hydrogen storage composition.

Abstract:

A method of coating a surface of a fuel cell plate is disclosed herein. The method involves forming a sol gel mixture including a metal oxide modified with at least one functional group, where the at least one functional group is configured to improve adhesion; and adding carbon modified with a hydrophilic functional group to the mixture, thereby forming a suspension. The suspension is applied to the surface of the fuel cell plate, and is activated to form a porous, hydrophilic, and conductive film on the surface of the fuel cell plate.
