Title: Smokeless vent system for a cooking appliance
Inventor: GRIFFEY DEAN I
IPC: F27D11/00
Filed: 2004-04-08
Granted: 2009-06-23
Abstract: A cooking appliance includes an exhaust system that substantially eliminates potential smoke generating byproducts carried by oven gases. The cooking appliance includes an oven cavity having a top wall including a recessed portion within which is mounted a broil element. A plurality of openings are formed in the recessed portion that allow exhaust gases to pass into a smoke elimination chamber. Heat generated by the broil element and in the smoke elimination chamber removes substantially all combustion byproducts contained in the exhaust gases. To further remove combustion byproducts, the exhaust gases are passed through a ceramic catalyst prior to being directed into a vent duct. From the vent duct, the exhaust gasses are directed past a blower into an exhaust duct that, ultimately, guides the exhaust gases from the appliance.

Abstract: Cette invention concerne la préparation d'une solution organique, si possible d'acides phosphoniques et de sels métalliques tétravalents, de préférence de Zr, Ti, Sn et Ce, dans des solvants organiques. Cette solution se comporte comme une solution de sels de métaux tétravalents, de préférence des phosphates-phosphonates, qui sont complètement insolubles dans les solvants connus. Cette particularité permet d'insérer facilement des particules des composés susmentionnés dans les pores des membranes poreuses, dans les matrices de ceux des polymères qui sont solubles dans les mêmes solvants organiques, ainsi que dans les interfaces membrane/électrode des piles à combustible. Les sels de métaux tétravalents, de préférence des phosphates-phosphonates de zirconium, dotés d'une forte conductivité protonique (supérieure dans certains cas à 10?-1¿ S cm?-1¿) permettent d'obtenir des membranes poreuses imprégnées et des membranes nanopolymères alliant de bonnes propriétés mécaniques et/ou une perméabilité réduite aux espèces gazeuses à une bonne conductivité protonique. Ces membranes peuvent donc s'utiliser dans des piles à combustible, même à des températures supérieures à 80 ·C. Leur forte activité catalytique les destinent également à des réacteurs à membranes catalytique.

Title: Valve pin cross over nozzle for stack mould
Inventor: RICK ROBERT
IPC: B29C45/32
Filed: 2003-11-12
Granted: 2011-04-05
Abstract: According to the present invention, a cross over nozzle (10) is provided of two parts (22,24) which, when joined, define a housing (20) having a passage (30) extending therethrough, a tapered valve seat (50) extending about the passage and a valve member (60) having a tapered valve head (62) disposed in the passage for engaging the valve seat. The two parts (64,66) are axially separable at an interface (68) extending through the valve seat/valve head. In order to open the valve, both valve parts are first joined and then moved together as one member in the same direction relative to the housing axially away from the valve seat. Similarly, the valve members are jointly moved into engagement with the valve seat before the cross over nozzle is separated.  Accordingly, unlike the valve gate design, the valve interface between the two parts of the valve head isn't exposed to molten resin and therefore molten resin isn't trapped therebetween to cause a string upon opening.

Abstract: A packet communication system (300) is disclosed that includes an end communication device (302), a call processing system (306), and a packet network (304). To setup up a call from an end user, the end communication device (302) transmits a call request message to the call processing system (306). The call request message has a header that includes priority information for the call. The call processing system (306) processes the priority information in the header of the call request message to determine if the call request message is for a high priority call. If the call request message is not for a high priority call and the call processing system (306) is in a state of congestion, then the call processing system (306) transmits a response message indicating the state of congestion. Responsive to receiving the response message, the end communication device (302) performs call blocking and provides call treatment to the end user.
