20130191366 | Pattern Matching Engine - A pattern matching engine and associated method for detecting one or more of headers, footers, watermarks, page numbering, page colors, and page borders appearing in a fixed format document. The pattern matching engine performs pattern matching across pages of the fixed format document to identify repeating patterns. Using heuristic analysis, repeating patterns meeting selected criteria are classified as headers, footers, or watermarks. Filtering removes repeating patterns unlikely to represent headers, footers, or watermarks. The information produced by the pattern matching engine allows the repeating elements to be properly reconstructed as flowable elements when converting a fixed format document into a flow format document. | 07-25-2013 |

20080201980 | Apparatus and method of enhancing the quality of high-moisture materials and separating and concentrating organic and/or non-organic material contained therein - The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement to improve boiler efficiency and reduce emissions. This is all completed in a low-temperature, open-air system. Also included is an apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. This is useful for segregating contaminants like sulfur and mercury from the product stream. | 08-28-2008 |

20140141381 | METHOD OF ENHANCING THE QUALITY OF HIGH-MOISTURE MATERIALS USING SYSTEM HEAT SOURCES - The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement. Coal can be intercepted on current coal feed systems ahead of the pulverizers. Drying fuel, such as coal, is done to improve boiler efficiency and reduce emissions. A two-stage bed utilized in the process first “pre-dries and separates” the feed stream into desirable and undesirable feedstock. Then, it incrementally dries and segregates fluidizable and non-fluidizable material from the product stream. This is all completed in a low-temperature, open-air system. Elevation of fan room air temperature is also accomplished using waste heat, thereby making available to the plant system higher temperature media to enhance the feedstock drying process. | 05-22-2014 |

20090056558 | POPCORN MACHINES WITH TOPPING DISPENSING SYSTEMS AND ASSOCIATED METHODS OF USE AND MANUFACTURE - Popcorn machines having topping dispensing systems are disclosed herein. A popcorn machine configured in accordance with an embodiment of the disclosure includes a popping kettle or other popping apparatus positioned in a cabinet. The popping apparatus is configured to heat un-popped corn kernels and pop the corn kernels. After popping, the corn is held in the cabinet. The popcorn machine of this embodiment further includes a topping outlet positioned in the cabinet and a topping pump. The topping outlet is operably connectable to a topping container, and the topping pump is configured to move topping from the topping container through the topping outlet and onto a serving portion of popcorn in response to operator activation of the pump. | 03-05-2009 |
20090126579 | POPCORN MACHINES AND OTHER MACHINES HAVING MULTIPLE HEAT ZONE COOKING SURFACES FOR PRODUCING POPCORN AND OTHER TYPES OF EXPANDED FOODS - Machines having multiple heat zone cooking surfaces for producing popcorn and other types of expanded foods are disclosed herein. In one embodiment, a kettle assembly for popping corn includes a popping surface having a first heat zone adjacent to a second heat zone. In this embodiment, the first heat zone is configured to receive a plurality of unpopped corn kernels, and heat the unpopped corn kernels to a first level. The second heat zone is configured to receive the unpopped corn kernels from the first heat zone, and heat the unpopped corn kernels to a second level, higher than the first level. In one aspect of this embodiment, the kettle assembly can include a first heating element positioned at least proximate to the first heat zone, and a second heating element positioned at least proximate to the second heat zone. The first heating element operates at a first temperature, and the second heating element operates at a second temperature, higher than the first temperature. | 05-21-2009 |
20130276641 | AIR POPCORN POPPER - Popcorn machines having fan assemblies and heat sources are described herein. The fan assemblies and the heat sources can be configured to provide heat to unpopped corn kernels to produce popcorn without the use of cooking oil. The popcorn machines can be configured for commercial use and can be mounted onto support structures that allow operators to rotate the popcorn machines. | 10-24-2013 |
