Title: Modular gas appliance system
Inventor: LEE DUANE A
IPC: F24C3/12
Filed: 1998-04-08
Granted: 2005-06-21
Abstract: The invention provides a modular gas cooktop system comprising a gas cooktop including compartments and standardized connections for a plurality of modular gas cooking units and an adapter. The standardized connections provide the maximum gas flow rates expected for use with the modular gas cooking units and the adapter provides gas flow rates compatible with the individual gas cooking units. The adapter automatically reduces the gas flow rate provided to a modular cooking cartridge to match the gas flow requirement of the particular cartridge. The adapter can be added to the cartridge during the manufacturing process, thereby eliminating the requirement of removing an existing orifice from the gas appliance and replacing it with a second orifice when installing the cartridge in the gas appliance. The invention further includes a method for adapting the gas flow rate available to a modular cooking cartridge in a gas appliance.

Title: Method and apparatus for maldi analysis
Inventor: LOUGH DAVID M
IPC: H01J49/04
Filed: 1997-09-19
Granted: 2003-06-17
Abstract: Matrix assisted laser desorption/ionization is performed in a manner to thermalize large analyte ions in a plume of desorbed material for spectroscopic analysis. The thermalized ions have a low or zero mean velocit y and are presented at a well-defined instant in time, reducing artifacts and sharpening the spectral peaks. In one embodiment the light is delivered to a  matrix or sample holder having a cover, baffle or compartment. The baffle or  compartment impedes or contains a plume of desorbed material and the analyte  undergoes collisions to lower its mean velocity and directionality. Thus "thermalized", the analyte ions are passed to a mass analysis instrument. In  a preferred embodiment, an optical fiber butts up against a thin transparent plate on which the specimen resides, with the matrix side in a vacuum acceleration chamber. A mechanical stage moves the specimen in both the x- a nd y-directions to select a point on the specimen which is to receive the radiation. The use of a fiber optic illuminator allows the entire stage assembly to be subsumed essentially within the dimensions of a conventional stage.

Title: Video transmission apparatus employing intra-frame-only video compression that is mpeg-2 compatible
Inventor: SONG DONG-IL
IPC: H04N7/26
Filed: 1998-08-12
Granted: 2003-09-23
Abstract: VIDEO TRANSMISSION APPARATUS EMPLOYING INTRAFRAME-ONLY     Intraframe-only video compression encoding of every successive video frame is done the way intraframe video compression encoding is done on I anchor frames in MPEG-2, and each frame is identified as being intraframe video compression encoded similarly to the way it is done on x anchor frames in MPEG-2. The encoder for doing this is simpler than that for coding P frames and B frames as well as I  frames, since there is no need for motion estimation circuitry. Using such an encoder in a digital camcorder reduces power drain on the battery and permits the weight and size of the camcorder to be reduced. Intraframe-only video compression facilitates editing video.    In many systems in which video editing is done an MPEG-2 decoder is already available, so there is no additional cost for a decoder to decode the transport stream of I Frames without intervening P or B frames. If an MPEG-2 decoder is not already available in a system, providing such a decoder is reasonable in cost, since the amount of hardware in an MPEG-2 decoder is considerably less than that in an MPEG-2 encoder.

Abstract: A preset is provided for providing access at selected locations to an underfloor electrical distribution system of the type consisting of at least one raceway panel adapted to be positioned in a concrete floor. The raceway panel defines an interior passage adapted to carry service cables and has an exterior wall defining a preset opening that provides access to the interior passage. The presets can be located at any location where an opening is punched in the raceway panel, with 12 inch or 24 inch intervals being mostcommon. The preset includes a housing having an interior compartment, a concrete cap, and a knockout section. The concrete cap and the knockout section can be removed to provide access to the interior compartment of the preset housing. The knockout is positioned to align with and lockingly engage with the preset opening to secure the preset to the raceway panel during pouring of the concrete floor. Upon hardening of the concrete floor, the concrete above the preset can be broken away to permit removal of the concrete cap. The knockout can then be removed to provide access to the interior passage of the raceway panel through the preset. Alignment clips are provided for securing and aligning presets carried by adjacent raceway panels. The side walls of the preset are beveled inwardly such that the base of the preset is larger than the top. This design further restricts vertical movement of the preset after the concrete has hardened.
