Title: Decorative direct vent fireplace
Inventor: ERICKSON PAUL ERIC
IPC: F24C15/00
Filed: 2003-05-09
Abstract: A direct vent fireplace unit that resembles an open hearth wood fireplace. The unit is installable in the interior of a dwelling above a surface defining an outer hearth. The unit includes an outer casing to define a cavity in the dwelling adjacent the outer hearth surface. A combustion chamber is provided having enclosing walls, a floor, a roof and an open front face with a combustion air inlet and an exhaust outlet communicating the combustion chamber with the exterior of the dwelling. The combustion chamber is mountable within the cavity of the outer casing such that the floor of the combustion chamber is substantially co-planar with the surface defining the outer hearth. A burner element for burning fuel within the combustion chamber is connectable to a fuel supply. A controller to control the burner element and a transparent cover mountable over the open front of the combustion chamber to seal the combustion chamber from the interior of the dwelling are also provided.  The fireplace unit recreates an open, wood fire ambience with active flames and a large front face for viewing the flames. The unit also enjoys improved heating efficiency over a traditional open fireplace while preserving the preferred active: flame appearance.
Patent CA-2429814-A1 (CA)
Title: Rna interference mediating small rna molecules
Inventor: TUSCHL THOMAS
IPC: C12N15/113
Filed: 2001-11-29
Abstract: Double-stranded RNA (dsRNA) induces sequence-specific post-transcriptional gene silencing in many organisms by a process known as RNA interference (RNAi). Using a Drosophila in vitro system, we demonstrate that 19-23 nt sho rt RNA fragments are the sequence-specific mediators of RNAi. The short interfering RNAs (siRNAs) are generated by an RNase III-like processing reaction from long dsRNA. Chemically synthesized siRNA duplexes with overhanging 3' ends mediate efficient target RNA cleavage in the lysate, and  the cleavage site is located near the center of the region spanned by the guiding siRNA. Furthermore, we provide evidence that the direction of dsRNA processing determines whether sense or antisense target RNA can be cleaved b y the produced siRNP complex.
