Title: Oven cavity construction
Inventor: JAY WILLIAM EDWARD
IPC: H05B6/80
Filed: 2000-09-13
Granted: 2008-06-17
Abstract: A convection cooking appliance includes an oven cavity and an air channel assembly that extends about at least a portion of the oven cavity.  The air channel assembly includes an air delivery section and a return section, both of which are preferably attached to the oven cavity through a quick latching connection. More specifically, the air delivery section is preferably mounted about an opening in a top wall of the oven cavity through a twist lock arrangement, while the return section is mounted about another opening formed in a bottom wall of the oven cavity also through a twist lock. In accordance with the most preferred embodiment, each of the openings provided in the top and bottom walls of the oven cavity is defined by substantially vertical flanges that define circular openings provided with various annularly spaced, radial projections which extend within respective slots formed in portions of the air delivery and return sections. The slots are preferably L-shaped such that bayonet-type connections are defined. The overall appliance also incorporates a microwave unit and a metal gasket is interposed at the connections of each of the air delivery section and the return section to the oven cavity in order to provide a continuous ground path between the components in order to contain the microwave energy.

Abstract: A call center includes a message playback unit for playing back a prerecorded greeting during an outgoing call while a call classifier unit within the call center processes an audible signal received from a remote party location. A call processing unit places a call to a remote party location via a communication network to attempt to elicit a desired response from the remote party. The call classifier then processes an audible signal received from the remote party location to determine whether or not the call was answered by a live party. The prerecorded greeting is then played while the call classifier is simultaneously processing the audible signal. If the call classifier determines that the call was answered by a live party, the call processing unit completes a talk path between the remote party location and a local agent at the call center who handles the remainder of the call. The call processing unit will normally wait until the greeting has ended to complete the talk path. If the call classifier determines that the call was not answered by a live party, the call processing unit will terminate the call.

Title: Stent coating
Inventor: SMITH SCOTT R
IPC: A61F2/06
Filed: 2000-06-06
Granted: 2009-01-27
Abstract: A stent having a polymeric coating for controllably releasing an included active agent. The polymeric coating inl-cudes a blend of a first polymeric material, which if alone, would release the age nt at a first, higher rate, and a second polymeric material, which if alone would release the agent at a second, lower rate ove r a longer time period. One stent coating utilizes a faster releasing hydrophilic polymeric material and a slower releasing hydrophobic material. One stent coating includes a blend of a faster releasing PLA-PEO copolymer and a slower releasing PLA-PCL copolymer. One active agent is Taxol. One use of the Taxol deliv-ering stent is to inhibit restenosis following angioplasty.

Abstract: Méthode et dispositif d'émission d'ondes sismiques radiales dans un milieu matériel par induction électromagnétique, utilisable notamment pour générer des ondes sismiques dans des puits tubés ou non ou dans une masse d'eau. L'émission d'ondes radiales est obtenue essentiellement en dilatant radialement un tube métallique au contact du milieu matériel sous l'effet d'une pression magnétique engendrée par induction électromagnétique, des ondes élastiques étant créées dans le milieu sous l'effet de cette dilatation. La pression magnétique est obtenue en connectant une bobine placée dans l' axe du tube avec un générateur de courant: générateur de choc, générateur à fréquence variable. Le pas d'enroulement de la bobine peut être constant ou variable. Le tube peut être par exemple rapporté dans un puits ou trou ou bien être une portion de tube d'un puits cuvelé. Il peut être également la paroi latérale d'une enceinte étanche que l'on immerge dans une masse d'eau pour y produire des ondes acoustiques ou sismiques. Applications à la prospection ou la surveillance sismique du sous-sol par exemple.

Title: Starch compositions and the use thereof in the wet-end of paper preparation
Inventor: LEONHARDT PETER
IPC: D21H17/28
Filed: 2001-06-20
Granted: 2009-08-04
Abstract: The present invention relates to compositions of starch. The compositions consist of an anionic and a cationic starch wherein at least one of the starches is waxy. The compositions are surprisingly not resulting in an agglomerated product when cooked. The compositions are used in paper or cardboard preparation. The compositions are cooked and added at the wet end of the paper production process. This results in a high possible addition level and the use of the size press is abolished. The resulting paper and board are shown to have better characteristics than the paper and board prepared with the same components which have not been mixed prior to addition but which are added separately.

Abstract: A method and system for transferring money from a sender to a receiver utilizing a computer network such as the Internet (12). The sender (16) visits a web site and identifies, to the server (34) over the Internet, the receiver (30), an e-mail address to the receiver (18), an amount of money to be transferred, and a withdraw account from which money is to be transferred. The withdraw account can be a checking account (56), a checking account secured by a credit card account (24), or a credit card account (26). Money is transferred from the withdraw account and preferably deposited into a holding account. The server automatically sends e-mail to a receiver, over the Internet, to inform the receiver that the sender has transferred money and to request the receiver to visit the web site of the server to receive money. The receiver visits the web site of the server in response to the e-mail and identifies a deposit account to which money is to be transferred.

In use, a foam cleaning agent is dispensed onto a location on the top surface (30T) of the brush (30) inwardly of the supply passages (30S). Rotation of the brush (30) generates a force urging dispensed foam cleaning went in a radially outwardly direction from the centerline (30A) of rotation toward the baffle (30F). The baffled deflects the foam cleaning agent into the supply passages (30S) and into the bristles (30L) of the brush (30).

Abstract: An integrated circuit logic topology or architecture suitable for low voltage differential logic operating at radio frequencies is disclosed. The topology, referred to as enhanced pseudo common mode logic, is similar to and compatible with traditional CML, and provides the additional advantage of eliminating the need for level conversion between consecutive logic gates, thereby increasing the potential maximum operating frequency of subsystems implemented using the invention. The invention retains most of the advantages of traditional CML, and in addition permits the independent selection of output logic high level and output logic low level so that they may be matched with the succeeding circuit input levels.
