Title: System and method for detecting debonding in rubber coated rolls
Inventor: DEVITT JOHN WILLIAM
IPC: G01N21/952
Filed: 2001-12-13
Abstract: An infrared inspection system and an induction heating system used in conjunction enable the inspection of rubber coated rolls, such as rolls used in the pulp and paper industry.

Title: A cylindrical reactor with an extended focal region
Inventor: DROZD MICHAEL J
IPC: H05B6/70
Filed: 2000-12-07
Abstract: An elliptical exposure chamber has an extended focal region. A plurality of cylindrical reactors (25) form the ex-tended focal region. Reducing the size of the opening (58) to each reactor (25) reduces the amount of energy reflected and increases the overall heating. In order to efficiently deliver the electromagnetic energy to the reduced opening (58), a tapered waveguide (55) has a concave end (56). A power splitter (42) divides power from a central waveguide (52) to the plurality of reactors (25). The power that is delivered to each reactor (25) can be adjusted by adjusting the impedance of each reactor (25), the width of each reactor (25) or the width of the opening (58) to each reactor (25). The width of the opening (58) to each reactor (25) can be controlled by a movable metal plate (44). A dielectric wheel can be used to shift hot spots along the focal region.

Title: Light tube system for distributing sunlight or artificial light singly or in combination
Inventor: EISENMAN JAMES A
IPC: F21V8/00
Filed: 2002-07-25
Abstract: Hybrid lighting systems use light distributor tubes to distribute artificial light and natural sunlight through the same distributor tubes. Devices for gathering uncollimated light from conventional sources (such as electrically energized arcs or filaments housed in evacuated or gas filled glass envelopes) and directing the light into the ends of tubes designed to distribute such light. Devices for gathering and concentrating inherently collimated sunlight to be fed into the same light distributing tubes used by the artificial light. One preferred embodiment comprises a light gathering and concentrating system in the form of a pair of opposed parabolic reflectors, one which is preferably large, e.g. having a diameter of five feet, and the other much smaller, e.g. the size of the much smaller distribution tubes. This light gathering system is connected to the light distribution tubes through a pair 90° elbows which are rotatable in the X and Y axis in order to track the location of the sun in the sky. The two parabolic reflectors are positioned to share a common focal point so that the larger reflector will direct the sunlight through the focal point of the smaller reflector, which will, reflect the light as concentrated, collimated light. A central aperture in the larger reflector passes the concentrated beam on its way to the distribution tubes.
