Filed:

Apr 19, 2013

Appl. No.:

13/866665

Inventors:

Jin Hu - Hudson OH, US
David B. Sweet - Canal Fulton OH, US

Assignee:

GOODRICH CORPORATION - Charlotte NC

International Classification:

B41J 11/00

US Classification:

347102

Abstract:

A heating element is provided with a conductive path pattern which can be printed in a mask-free manner (e.g., drop-on-demand) with existing printing technology. The printing step can be performed, for example, with a thermal inkjet printer, a piezoelectric inkjet printer, an aerosol jet printer, or an ultrasound printer. The ink solution can be formulated so that it establishes an electrically conductive path which is free of polymer binders.

Appl. No.:

6/279884

Inventors:

Lowell J. Adams - Tallmadge OH
David B. Sweet - Hartville OH

Assignee:

The B. F. Goodrich Company - New York NY

International Classification:

B64D 1512

US Classification:

244134D

Abstract:

A device (10) for isolating from vibrational and impulse loads a power transfer unit (14) that transfers power from a helicopter electrical system to a plurality of deicing segments on the rotor blades includes a distributor (13) rotating with the rotor blades for distributing power from the power transfer unit (14) to the deicing segments, a housing (11) having an upper cylinder (24) and lower cylinder (23) the latter of which is flexibly secured to the helicopter as by a joint including ball (40), housing 11 substantially isolating the power transfer unit (14) from such loads, and a shaft (12) rotatably engaging the upper cylinder (24) for carrying the distributor (13) in rotation with the rotor blades.

Appl. No.:

5/771707

Inventors:

David B. Sweet - Akron OH

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

H02K 1300

US Classification:

310239

Abstract:

A brush assembly for use with rotating slip rings wherein a plurality of brush modules composed of flat separate elements with brushes therein are assembled in a stacking order with spacers selectively placed between modules to facilitate the positioning of the brushes opposite the slip rings. Each module is molded separately to provide ease of molding, assembling and maintenance.

Filed:

Jan 21, 1998

Appl. No.:

9/010379

Inventors:

Michael J. Giamati - Akron OH
James C. Putt - Doylestown OH
David B. Sweet - Canal Fulton OH
Tommy M. Wilson - Stow OH

Assignee:

The B. F. Goodrich Company - Charlotte MN

International Classification:

B64D 1512

US Classification:

244134R

Abstract:

A deicer comprises a skin heating device immediately subjacent an outer skin overlying an apex of a leading edge, and a skin deflection device immediately subjacent the outer skin chordwise aft of the apex. The skin heating device prevents the formation of ice over the apex and the skin deflection device deflects the outer skin to expulse ice formed chordwise aft of the apex. A controller controls the heating and deflection cycles to minimize power consumption of the deicer.

International Classification:

B64D 1512

US Classification:

244134D

Abstract:

A deicer for use on the propeller of an aircraft wherein the heating elements or elements of the deicer which are embedded in an electrically non-conductive material adhered to a propeller blade provide a gradient type of heat distribution pattern having the greatest heat concentration at the area of the propeller closer to the shank end and a lower heat concentration at the area of the propeller further away from the shank end.
