Filed:

Feb 2, 2001

Appl. No.:

09/776318

Inventors:

Paul S. Christian - Dunstable MA, US
Chad S. Klotzle - Acton MA, US

Assignee:

Diamond Antenna & Microwave Corp. - Littleton MA

International Classification:

H02K 13/00

US Classification:

310219

Abstract:

A compression journal for transfer of microwave signals across a rotating interface of a rotary joint comprises a silver impregnated graphite split ring stator which surrounds and is in contact with a coin silver sleeve of a shaft rotor when a rotor assembly is positioned within a stator assembly. At least one O-ring is placed over the outside of the split ring stator to allow slight compression of the silver/graphite split ring stator to maintain continuous electrical contact between the stator and the rotor. A beryllium-copper radial shield is secured to the end of the compression journal securing it within a cavity of the stator assembly. The compression journal floats within the stator assembly to allow rotor/stator concentricities to adjust and seat properly for long term performance.

Appl. No.:

10/716358

Inventors:

Xiandong Wang - Acton MA, US
Paul A. Christian - Norton MA, US

Assignee:

The Gillette Company - Boston MA

International Classification:

H01M 4/36

US Classification:

42923195, 4292181, 429220

Abstract:

A primary battery includes a cathode having an oxide containing one or more metals and pentavalent bismuth, an anode, a separator between the cathode and the anode, and an alkaline electrolyte. The metal(s) can be an alkali metal, an alkaline earth metal, a transition metal, and/or a main group metal. The separator can be ion-selective or capable of substantially preventing soluble bismuth ionic species from diffusing from the cathode to the anode.
