US Patent:

8222189, Jul 17, 2012

Filed:

Dec 13, 2005

Appl. No.:

12/084604

Inventors:

Clark V. Cooper - Arlington VA, US
Michael F. Mullen - Cheshire CT, US

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F16C 33/04
C10M 103/02

US Classification:

508105, 508103

Abstract:

There is a coated, dynamic contact surface. The contact has a substrate and a carbon-based coating on the substrate. The coating has a coefficient of friction of about 0. 5 or less and an atomic hydrogen content of about 5% to about 25%. There is also a mechanical system. There is a method for increasing oil-out survivability in a mechanical system.

International Classification:

H04B 1/02

US Classification:

367137

Abstract:

A system for transmitting power and data through a solid medium includes a power signal transmitter configured to acoustically transmit power through the solid medium to a power signal receiver using a first frequency and a data signal transmitter configured to acoustically transmit data through the solid medium to a data signal receiver using a second frequency. The second frequency may be offset from the first frequency and from at least a first overtone of the first frequency. Furthermore, the data signal transmitter and data signal receiver may be positioned at a null of a pattern of acoustic waves produced by operation of the power signal transmitter. The system may further include a notch filter coupled to receive an electrical output of the data signal receiver, the notch filter being tuned to attenuate the first frequency.

International Classification:

C23C 14/46

US Classification:

20419211

Abstract:

A method for increasing oil-out survivability in a mechanical system having a plurality of components each having a least one surface, includes placing at least one of the plurality of components into a vacuum chamber having at least one broad-beam ion gun; supplying an inert gas to the broad-beam ion gun; accelerating the ionized inert gas to high kinetic energy; cleaning the surface of the component with the ionized and accelerated inert gas; supplying a hydrocarbon gas having at least 25 wt % acetylene to the broad-beam ion gun; ionizing the hydrocarbon gas; accelerating the ionized hydrocarbon gas to high kinetic energy; and directing the ionized and accelerated hydrocarbon gas to the surface of the component at a temperature of about 300 F. or less to deposit a carbon-based coating thereon.
