Patent CA-2459368-A1 (CA)
Title: Venturi barometric draft regulator
Inventor: SCOTT LIONEL A
IPC: F23L17/06
Filed: 2004-03-01
Abstract: There is provided a tee fitting having two longitudinal connectors and a single side connector, the longitudinal connectors adapted to be connected to a furnace and a flue stack and the side connector adapted to be connected to a draft regulator, wherein a venturi is formed along an interior of the longitudinal side directly behind the side connector. The tee fitting uses the venturi principal to create a negative pressure directly behind the door of a standard barometric damper when the burner is in operation and the flue gases are flowing to the flue resulting in less bleed air injected into the flue gas stream, higher temperature gas delivered to the base of the flue, and maintainance of proper over the fire pressure. More heat may be extracted by a heat exchanger, increasing the steady state efficiency, while still protecting the flue from condensation. When the appliance is off, the venturi provides a further advantage, in that the draft door remains closed at higher natural flue draft and less room air escapes up the flue, reducing the annual fuel usage.

Title: Method for gene isolation by cre-trap cloning
Inventor: SLECKMAN BARRY P
IPC: C12N15/85
Filed: 2003-08-26
Abstract: The disclosure describes a method for isolating genes encoding proteins that regulate the expression of target genes of interest, said method designated herein for convenience by the term: "Cre-Trap cloning." In brief, the Cre-trap cloning method of the invention involves modifying a target gene of interest such that it encodes the Cre recombinase and Herpes simplex virus (HSV) thymidine kinase (TK) proteins. This step is followed by mutagenesis and selection for cells which have lost target gene expression by virtue of their resistance to ganciclovir (a nucleoside analog structurally related to acyclovir), which kills cells expressing HSV TK. Cell lines that have lost target gene expression due to mutations in genes encoding traps-acting factors are then transiently transfected with a cDNA library from the parent cell line in a novel expression vector (pCT.l, shown in Figure 1). Expression of a cDNA  that complements the genetic mutation results in expression of the target gene and production of the Cre recombinase, which modifies pCT.I in such a way that it is readily isolated from pCT.I plasmids with cDNAs that do not activate target gene expression.

Title: Lamp base adapter
Inventor: TUFANO ANTHONY SR
IPC: H01R33/90
Filed: 2005-03-23
Abstract: A lamp adapter can adapter a mogul base lamp holder to accept a medium base lamp. The lamp adapter can accommodate only open fixture rated lamps. An open end of the lamp adapter into which a lamp is inserted has an elongated flange which allows only an open fixture rated lamb having a medium base to be completely threaded into the adapter and make electrical contact with a threaded metal sleeve and central button contact of the lamp holder. The geometry of the elongated flange prevents the threading of a closed fixture rated lamp into the adapter by taking advantage of the physical differences between the open and closed fixture rated lamps.
