Patent number: 5910710Abstract: An electrodeless lamp waveguide structure includes tuned absorbers for spurious RF signals. A lamp waveguide with an integral frequency selective attenuation includes resonant absorbers positioned within the waveguide to absorb spurious out-of-band RF energy. The absorbers have a negligible effect on energy at the selected frequency used to excite plasma in the lamp. In a first embodiment, one or more thin slabs of lossy magnetic material are affixed to the sidewalls of the waveguide at approximately one quarter wavelength of the spurious signal from an end wall of the waveguide. The positioning of the lossy material optimizes absorption of power from the spurious signal. In a second embodiment, one or more thin slabs of lossy magnetic material are used in conjunction with band rejection waveguide filter elements. In a third embodiment, one or more microstrip filter elements are tuned to the frequency of the spurious signal and positioned within the waveguide to couple and absorb the spurious signal's energy.Type: GrantFiled: November 22, 1996Date of Patent: June 8, 1999Assignee: Fusion Lighting, Inc.Inventor: James E. Simpson

Patent number: 5847517Abstract: Ignition of an electrodeless lamp, energized by microwave or radio frequency energy, is achieved by disposing a ferroelectric igniter in the lamp envelope along with the fill material. The igniter responds to switching of its spontaneous ferroelectric polarization by emitting electrons that collide with the atoms of the fill material to discharge further electrons and ultimately provide emission of light. In the preferred embodiment, the microwave or radio frequency energy used to excite the fill material is applied to the ferroelectric igniter to cause switching of its spontaneous ferroelectric polarization. Another preferred feature is the securing of the igniter, in the form of a thin patch or wafer, to the inside surface of the lamp envelope in a generally perpendicular orientation to the electric field in the microwave excitation energy.Type: GrantFiled: July 10, 1996Date of Patent: December 8, 1998Assignee: Fusion Lighting, Inc.Inventors: Michael Ury, David Hammer, Czeslaw Golkowski

The common sample flow path, including the sample sizing loop, is automatically cleaned with rinse solvent between loading of successive samples into the sizing loop. Multiple programs may be employed to control the processing times for different types of sample fluid. A sample container closure member having a unique sealing insert member is provided to preclude leakage of fluid from the sample storage container when the container is pressurized.Type: GrantFiled: July 11, 1991Date of Patent: April 28, 1992Assignee: Analytical Bio-Chemistry Laboratories, Inc.Inventors: Daniel L.

Patent number: 5103653Abstract: A refrigeration system employed as an icemaker, in which part of the ice so produced is stored in a bin, and in which, part of the ice is then melted to provide a supply of purified water in a container. In one embodiment convection flow of air conveys heat from the ambient room environment to the bottom of the ice bin to achieve this melting. In a second embodiment a convection flow of water is employed for this purpose. Controls are provided to automatically control melting, to maintain a predetermined level in the purified water container.Type: GrantFiled: January 29, 1991Date of Patent: April 14, 1992Assignee: Thermadyne, Inc.Inventor: John D.
