Patent CA-2570842-A1 (CA)
Inventor: TURSKY JOHN M
IPC: B01D53/34
Filed: 2004-06-18
Abstract: A catalytic converter for an internal combustion engine exhaust system comprises a single-piece, seamless metal housing having tubulated gas inlet and outlet ports and a tubulated intermediate section with a plurality of cascaded catalytic element therein. The intermediate section is connected to the inlet port by an inlet transition section and to the outlet port by an outlet transition section. The inlet and outlet ports and the inlet and oulet transition sections are formed by swaging the ends of a seamless tube used to form the housing. Exhaust gas produced by operation of the engine passes into the converter and through the catalytic element. Noxious substances in the exhaust, including CO, NOx, and incompletely combusted hydrocarbons are converted to more benign substances trough the action of the catalytic element, which is preferably a frangible ceramic honeycomb structure having a plurality of internal passages coated with a catalitycally active substance. A  swaging process is used to form tubulated ends on the converter. The tabulated ends minimize production of turbulence in the gas flow and allow the converter to be connected to the rest of the exhaust system by clamped, welded, of flanged joints. The one-piece, seamless construction of the converter is economical to produce and eliminates welding of housing components that tend to fail when subjected to corrosive exhaust gasses over a prolonged period of time.

Title: Improved furniture leg floor protector
Inventor: DESMARAIS PIERRE
IPC: B29C45/14
Filed: 2007-04-20
Abstract: The present invention relates to a furniture leg floor protector. The invention is an improvement over the prior art in that firstly it has a flexible upper sleeve which is stretchable and adapted to receive a leg of almost any shape and dimension.  This overcomes previous problems with floor protectors which after a certain age and wear, and because of semi-rigid construction, tend to fall off the furniture legs.  The invention also presents a method of installing the felt pad on the bottom of the floor protector by means of molding around the pad during molding of the floor protector. This not only fixedly secures the pad to the rest of the floor protector in an integral manner; but also alleviates applying the pads to the floor protector by means of adhesive as a second step in the manufacturing process after molding.
