US Patent:

58006826, Sep 1, 1998

Filed:

Oct 8, 1996

Appl. No.:

8/731038

Inventors:

Gustavo Cerri - Boonton NJ
Kin Ching Kong - Woodside NY

Assignee:

AlliedSignal Inc. - Morristown NJ

International Classification:

B01D 300
C07C 17383

US Classification:

203 99

Abstract:

A liquid and vapor phase processes for the production of difluoromethane in which the risk of exposure to, and equipment fouling from, chlorofluoromethane is reduced. This reduction is accomplished from removing a sidestream containing monochloromonofluoromethane from a fluorination process distillation column.

Assignee:

AlliedSignal Inc. - Morristown NJ

International Classification:

B01D 334

US Classification:

203 67

Abstract:

The present invention provides a method for separating dichlorodifluoromethane from difluoromethane. More specifically, a process is provided for separating dichlorodifluoromethane and difluoromethane using azeotropic distillation.

International Classification:

H01R 3908

US Classification:

439 19

Abstract:

A flexible band-gear system has an ring gear assembly with bands in electrical contact with and a ring gear in mechanical engagement with corresponding bands and gears of planet gear assemblies which are in turn in electrical contact and geared engagement with a sun gear assembly mounted to a rotating shaft. Electrical power and/or an electrical signal can thus be conducted across a rotating joint which also transfers mechanical power. The flexible band-gear system can also be used in linear applications to transfer electrical power/signal via rolling contact with a linear band. The geared aspect of the system simplifies axial alignment and maintains the relative positions (within the ring annulus) of the planet gears. Electrical power and signal capacity can be varied with the number of planet gears in the system. Multiple channels are added using segmented contact bands and/or multiple contact band layers.

Kin Yuen Kong - Baldwin NY

Assignee:

Honeybee Robotics, Inc. - New York NY

International Classification:

H01R 3900

US Classification:

439 13

Abstract:

A multi-channel band-gear system for a rotary joint has a ring gear assembly with a conducting ring band in electrical contact with corresponding conducting bands of a set of intermediary planetary gears, which in turn are in electrical contact with a conducting sun band of a sun gear assembly. The ring band is formed with a plurality of conducting segments which are electrically insulated from each other and positioned angularly in a circumferential direction of the ring gear, such that separate electrical power/signal channels are formed across the rotary joint. In a preferred embodiment having continuously connected channels, the ring band has four conducting segments at 90. degree. intervals, the sun band has two conducting segments at 180. degree. intervals, and three planetary bands are in rolling electrical contact at 120. degree.
