Appl. No.:

12/765274

Inventors:

Thomas O'Brien - Mount Prospect IL, US
John Michael Whitehouse - Naperville IL, US

Assignee:

RECYCLED ENERGY DEVELOPMENT, LLC - Westmont IL

International Classification:

F26B 3/00
F26B 25/00
F26B 19/00

US Classification:

34500, 34236, 34 86

Abstract:

A process and apparatus used for heating and drying a material. The process uses supplemental radiant heat supplied by circulating thermal oil that is heated using fuels, as well as exhaust heat from other sources. The supplemental heat replaces a portion of the heat provided by the direct-firing. The supplemental heating is achieved by retrofitting existing direct-fired or radiant heat gypsum dryers with thermal oil-to-air heat exchangers in the combustion air lines and the air recirculation lines. Heated thermal oil is circulated through the exchangers, providing supplemental heat to both the combustion air and the re-circulated dryer air. The existing natural gas burners are fired to achieve the desired exit temperature. A Organic Rankine Cycle (ORC) system is coupled to the dryer exhaust vent to recapture heat energy produced by the thermal oil and produce electricity.

Appl. No.:

6/594035

Inventors:

Thomas P. O'Brien - Deerfield IL

Assignee:

Tokyo Shibaura Denki Kabushiki Kaisha

International Classification:

G21K 104

US Classification:

378160

Abstract:

A high speed actuator for controlling the shutter in x-ray equipment so as to eliminate transition time during which the x-ray dose is wasted. The actuator includes a driving solenoid for rotating and axially displacing a shutter member so as to move a shutter aperture to an open position, a mechanical arrangement for blocking movement of the member when the shutter aperture reaches the open position, and an electro-magnetic brake, having an armature and coil, interconnected with the driving solenoid such that braking engagement between the armature and coil is effected by movement of the shutter member and aperture to the open position.

Assignee:

Kabushiki Kaisha Toshiba - Kawasaki

International Classification:

G02B 718
G02B 2722
G02B 1700
G02B 510

US Classification:

350144

Abstract:

A three-dimensional display system comprising a display member on which viewing perspective changes as a function of viewing angle and a two axis remote control gimbal onto which the display is mounted to permit a user of the display to maintain contact with a control console while changing the angular view of the display.

Appl. No.:

6/764116

Inventors:

Thomas P. O'Brien - Deerfield IL

International Classification:

G01J 120

US Classification:

250201

Abstract:

A system for accurately controlling the motion of a mirror membrane used in a three-dimensional display system. The system senses the pressure differential across the membrane mirror as a means of indirectly measuring mirror position. This pressure differential is converted into an electrical signal which is used in a closed loop feedback system to force the membrane position to follow accurately the command signal.

Richard T. Bernardi - Prospect Heights IL

Assignee:

Kabushiki Kaisha Toshiba - Kawasaki

International Classification:

G21K 102
G21K 300

US Classification:

378148

Abstract:

A collimator blade assembly for a computed tomographic X-ray scanner comprising a blade of X-ray beam stopping material having an aperture for passing X-rays and an X-ray penetrable member closing at least a portion of that aperture to reinforce the material and thereby minimize collimator blade/detector clearances while preventing undesirable collimator blade vibration.

Appl. No.:

14/544070

Inventors:

- City of Industry CA, US
Boris Quijada - Beach Park IL, US
Thomas O'Brien - Antioch IL, US

International Classification:

G05D 23/13

Abstract:

Embodiments include thermostatic valves for showers and tubs in which the temperature is regulated by a thermostatic motor/element. Both the flow from the valve and the temperature are controlled by a rotary stem. Hot and cold water is pre-mixed by passage through the coils of a return spring into a mixing chamber and a ceramic valve at the top of the mixing chamber controls flow of mixed water from the mixing chamber into an outlet chamber where fluctuations in the water temperature are eliminated before the water is conveyed to the shower or tub.
