Title: Adaptive microwave oven
Inventor: VESCHI JOHN P
IPC: H04M1/72415
Filed: 2000-09-11
Abstract: The present invention provides an adaptive microwave oven capable of entering an operation mode which avoids interference with a communication device either upon detection of a communication from a communication device (e.g., a cordless telephone) operating in a microwave frequency range, or upon receipt of a command indicating the operation of a microwave device such as a cordless telephone through a suitable network (e.g., a piconet using BLUETOOTH.TM. Technology). In one embodiment, a cooking mode of a microwave oven is paused (or significantly reduced) to best avoid interference with microwave signals between a remote handset and a matching base unit of a cordless telephone. The activity of microwave communications within the vicinity of the adaptive microwave oven can be determined, e.g., using a passive cordless telephone receiver which detects communication activity in the microwave range, or using direct communications from the cordless telephone using a suitable wireless network, e.g., a piconet using BLUETOOTH.TM. Technology. In another embodiment, the frequency of an adaptive microwave oven capable of generating microwave energy at any of a plurality of microwave frequency ranges is controlled in accordance with the microwave frequency used by an electronic device (e.g., a cordless telephone) in the vicinity of the adaptive microwave oven. In this embodiment, a cordless telephone receiver can provide a controller for the adaptive microwave oven with passively detected information regarding the frequency of communication traffic in the vicinity of the microwave oven, or a wireless network can be used to provide frequency information directly between the relevant electronic device (e.g., cordless telephone) and the adaptive microwave oven.

Abstract: A fibrous article that generates heat upon application of electrical power is formed, for example, by joining stitch and loop yarns to form a fibrous prebody, with the loop yarn overlaying the stitch yarn at a technical face and forming loops at a technical back of the fabric prebody. An electrical resistance heating element, e.g., in the form of conductive elements, is joined with the stitch and loop yarns in the prebody at symmetrical and/or asymmetrical spaced-apart intervals as the stitch yarn, the electrical resistance heating elements extending between opposite edge regions of the fibrous article and conductor elements, e.g. located along edge regions, connect the electrical resistance heating elements to a source of electrical power. The technical face and/or the technical back of the fabric body may have fleece formed by finishing non-conductive fibers of the stitch yarn and/or loop yarn in a manner to avoid damage to electrical conductance of the electrical resistance heating elements. Preferably, the conductive elements have the form of a conductive yarn with one or more of: a core of insulating material, an electrical resistance- heating element, e.g., about the core, and a sheath material surrounding the electrical resistance-heating element (and core).

Abstract: A heat transfer system is described for controlling the transfer of heat from a roof space into a living space of a building. The heat transfer unit (10) includes a flexible duct (14) and a ceiling vent (16) for transferring warm air from within the roof space (12) into a living space (18) below. An electric fan (20) located at the top end of the flexible duct (14) is arranged to draw warm air from the roof space (12) down through the duct (14) into the living space (18). A first temperature sensor (22) mounted adjacent the top end of the flexible duct (14) senses the temperature of the air within the roof space (12). A second temperature sensor (24) located in the room below senses the temperature of the air within the living space (18). An electronic controller (26) controls the operation of the electric fan (22) in response to temperature sensing signals from the first and second temperature sensors (22, 24) respectively. In particular, the controller (26) ensures that the electric fan (22) is only activated when the air temperature within the roof space exceeds the air temperature within the living space by a predetermined temperature difference. The unit (10) can also be employed in a cooling mode.

Title: System and method for high speed dewatering of slurries
Inventor: HODGES MICHAEL K
IPC: C02F11/12
Filed: 2001-05-02
Abstract: A system and method for dewatering a continuous stream of slurry at high flow rates demonstrates enhanced efficiency, economy and ease of operation. A stream of slurry is subject to continuous or continual measurement of flow rate and pulp density and the measurements are used to control the rate of addition of a flocculating agent to the slurry. The flocculated slurry is delivered to a dewatering unit where it is passed through a diffuser and evenly delivered to a tracking screen for filtering solids from a liquid filtrate. The pulp density of the filtrate may also be measured and used to control addition of a flocculating agent. The tracking screen is adjusted to achieve an angle of repose suited to the particular composition of the filter cake. The diffuser has a base having a horizontal section aspect ratio of from about 1:1 to about 4:1 and continuously changing vertically into an upper portion having a horizontal section with an aspect ratio of from about 40:1 to about 100:1. The ratio of the horizontal sectional areas at the upper portion with respect to the base is from about 1:1 to about 3:1. The dewatering unit of the invention may be adjustably mounted on a transport means for deployment of the high speed dewatering system and method at any convenient location.
