Patent CA-2494877-A1 (CA)
Inventor: HIRSCH ROBERT
IPC: F23M20/00
Filed: 2005-01-28
Abstract: The gas-fired heater, especially a water heater, has an atmospheric gas burner (5) arranged within a nearly or completely closed combustion chamber (2) and associated with a premixing gas/air supply system (8) with a fuel gas feed nozzle (10). In order to avoid oscillations, which lead to sound waves and combustion instabilities, an oscillation-damping air supply chamber (11, 11', 11") is connected to the entrance (8a) of the gas/air supply system (8) for combustion air, within which the fuel gas feed nozzle is arranged. The air supply chamber (11, 11', 11") is provided with at least one air entrance (12, 12', 12"). The air supply chamber can be box-like, duct-like embracing or extending around the combustion chamber or it can be a pipe with different diameter pipe sections.

Patent CA-2498503-A1 (CA)
Inventor: DOBSON DAVID
IPC: A01B73/04
Filed: 2005-02-25
Abstract: The transversely extending frame of a machine has a number of hingedly interconnected frame sections that may be raised and lowered by lift cylinders to convert the machine between a wide- spread working position and a folded-up transport position. Two lift cylinders for raising and lowering inner wing frame sections relative to the central main frame section are anchored at their inner ends to a hydraulically operated holding cylinder that effectively adjusts the positions of the anchor points of the lift cylinder in a lateral sense. Thus, when the holding cylinder is fully contracted, the inner wing frame sections may be lowered by their lift cylinders until the lift cylinders are fully extended, but the outer ends of the inner wing flame sections remain tilted upwardly to a certain extent. Thus, outer wing frame sections connected to the outer ends of the inner wing frame sections also remain slightly lifted off the ground until fully unfolded from the inner wing frame sections. Thereupon, the holding cylinder may be extended to gently lower all wing frame sections to the ground without damaging tools or mounting components for such tools.

Patent CA-2509014-A1 (CA)
Inventor: ELIZAROV MICHAEL G
IPC: G06F17/27
Filed: 2005-06-02
Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Patent CA-2510288-A1 (CA)
Title: Bone regeneration
Inventor: CAMPBELL EWAN JAMES
IPC: A61K35/12
Filed: 2005-06-20
Abstract: The present invention is based on the discovery that when a tooth primordium is inserted into a mammalian jaw and tooth formation follows, new alveolar bone around the new tooth forms. The present invention is based on the idea of stimulating new tooth formation via the implantation of tooth primordia at selected places in the jaw (e.g. at four points in the mole regions) to result in the formation of bony protuberances which could facilitate denture retention. The teeth may then be removed from the jaw of the patient to leave the new alveolar bone.
