Turbine Head Assembly With Inlet Valve Driven By A Forward Positioned Actuation Assembly

US Patent:
5810276, Sep 22, 1998
Filed:
Nov 24, 1992
Appl. No.:
7/980954
Inventors:
Erik A. Fiske - Tujunga CA
Earl W. Presson - Brownsboro AL
International Classification:
B65H 7548, B64C 0000
US Classification:
2423905
Abstract:
A turbine head assembly is provided for use with an aerial tow reel assembly. The turbine head includes permanently open aft exhaust ports and a turbine assembly upstream of the exhaust port. The turbine head assembly features a housing with an open inlet. A split balanced butterfly valve assembly is provided at the open inlet of the housing. An actuation assembly drives a pair of baffle doors about a vertical axis with the baffle doors being arranged so as to automatically rotate inward into a closed position whenever there is a power outage in flight. This fail-safe feature avoids turbine overspeeding. The actuation assembly is positioned closer to the inlet and the butterfly valve assembly than to the turbine assembly. This placement of the actuation assembly closer to the inlet allows for the use of a gear assembly with a complimentary torque arrangement which is quick to respond to sensed changes in cable speed by a control system which signals the motor to vary the degree to which the baffle doors allow air to enter the air passageway leading to the turbine blades. The actuation assembly is also placed external to the guiding wall of the air passageway as well as the outer skin of the nacelle housing.

Fluid Jet Cutting System

US Patent:
2004013, Jul 8, 2004
Filed:
Aug 13, 2003
Appl. No.:
10/639764
Inventors:
Mark Langford - Harvest AL, US
Roland Fuentes - Owens Cross Roads AL, US
Jerry Kelley - Decatur AL, US
Ronald Walker - Falkville AL, US
Manfred Segewitz - Huntsville AL, US
Earl Presson - Brownsboro AL, US
International Classification:
B24B001/00, B24C001/00, B24C005/00
US Classification:
451/038000, 451/091000, 451/099000
Abstract:
A method and apparatus for preventing water from entering the abrasive port of an entrained high pressure fluid jet nozzle and a method and apparatus for attaching the high pressure fluid jet nozzle to a hazardous duty robot. The invention includes the application of a positive air pressure to an abrasive line preferably during those times when there is insufficient vacuum generate by high pressure fluid being sent through the restricted orifice in the high pressure nozzle. The invention prevents clogging of a fluid jet cutting system during operation. The invention includes mounting a nozzle and/or visualization system to an expandable and contactable component such as a grasping device that allows for continued use of the expandable and contractible grasping unit. This includes, for example, a grasping device that is provided out the end of a movable robot arm and that allows for rotation of the grasping device.
