Patent number: 6676403Abstract: The invention is related to a candle holder for various candle diameters, whereby the candle (4) is clamped between at least two clamping surfaces to clamping edges (1, 2, 3; 1a, 2a, 3a, 4a; 1b, 2b, 3b, 4b) which are movable in respect to each other and are in general moved towards each other by means of a spring. In case of the known candle holders the candle is extinguished when the melting zone of the burning candle approaches or reaches the clamping surfaces. The characteristic of the candle holder is that there is under the clamping surfaces (1, 2, 3; 1a, 2a, 3a, 4a; 1b, 2b, 3b, 4b) a candle chamber (6) which has an opening at the upper side, which opening is partly or completely closed when the clamping surfaces move towards each other.Type: GrantFiled: December 7, 2001Date of Patent: January 13, 2004Inventor: Theodorus Gerhardus Potma

Patent number: 6676402Abstract: Sequenced pulses of light from an excitation laser with at least two resonator cavities with separate output couplers are directed through a light modulator and a first polarzing analyzer. A portion of the light not rejected by the first polarizing analyzer is transported through a first optical fiber into a first ignitor laser rod in an ignitor laser. Another portion of the light is rejected by the first polarizing analyzer and directed through a halfwave plate into a second polarization analyzer. A first portion of the output of the second polarization analyzer passes through the second polarization analyzer to a second, oscillator, laser rod in the ignitor laser. A second portion of the output of the second polarization analyzer is redirected by the second polarization analyzer to a second optical fiber which delays the beam before the beam is combined with output of the first ignitor laser rod.Type: GrantFiled: August 10, 2001Date of Patent: January 13, 2004Assignee: The Regents of the University of CaliforniaInventors: James W.

Patent number: 6666207Abstract: A solar energy concentrator (1) is formed in the shape of a spiral horn, so that solar energy incident over a wide range of incident angles on the mouth (2) of the horn is concentrated by multiple reflections from inner walls (5) of the horn to emerge from an exit aperture (3) at the center of the horn. Solar energy emerging from the collector may be distributed by light pipes (40) to illuminate a building or may be transmitted to a solar energy conversion chamber (50) having a small entry aperture (51). The entry aperture (51) acts as black body absorbing all solar energy incident upon it and the solar energy may be converted within the chamber (50) either by photovoltaic cells and/or by heat absorbing media.Type: GrantFiled: August 6, 2001Date of Patent: December 23, 2003Assignee: Prometheus Technology, Inc.Inventors: Evangelos Arkas, Nicholas Arkas

Patent number: 6561793Abstract: A method of forming a porous ceramic matrix for use in an infrared heating unit comprises the steps of mixing ceramic fibers, organic binders and particulate material capable of infrared emissivity with an ionic wetting agent to form a moldable ceramic mixture, and molding the mixture to a desired shape. A ceramic matrix with infrared emissivity particles substantially uniformly distributed through the matrix is formed which results in a high intensity, high thermal efficiency matrix for use in an infrared heater. In a further aspect, the matrix can be formed using at least two different compositions of ceramic fibers each composition having a different melting temperature. During operation of the matrix in a heater unit over normal operating temperatures, melting and re-crystallization of the ceramic fibers with the lower melting temperature occurs resulting in the creation of crystalline bond regions between the two fiber compositions.Type: GrantFiled: August 14, 2000Date of Patent: May 13, 2003Assignee: Honeywell ASCa Inc.Inventor: Dave Narasimhan
