Patent CA-2262419-A1 (CA)
Inventor: MAERK MARCO
IPC: B60C5/04
Filed: 1999-02-22
Abstract: The invention relates to a novel wheel which serves for equipping with a pneumatic tire and essentially realizes two apparently incompatible properties of solid rubber tires and pneumatic tires, namely strength and good shock absorption, in a single wheel. This wheel is distinguished by the fact that it has a toroidal hollow foam member enclosed by the pneumatic tire and comprising reversibly deformable material having a large number of enclosed cavities serving for the absorption of gas. The substantial advantage of the tire according to the invention is obvious. Damage to the tire skin by a stone or nail does not in fact inevitably lead to an immediate and complete loss of air, as is often the case with known tires. Thus, the toroidal hollow foam member can itself store air in its cells, which not only permits continued riding for a certain time but also reduces the risk of accidents in the event of damage to the tire. Further advantages of the tire according to the invention are that the sound-insulating properties of the foam reduce the running noises of the wheel and that the foam torus optionally enclosed in an inner tube is hollow inside, which simplifies the removal of the pneumatic tire from the rim.

Inventor: SWEENEY RICHARD P
IPC: A47J31/40
Filed: 1999-11-25
Abstract: An automated beverage brewing system includes a liquid storage tank and a metering chamber. The metering chamber is at least partially submerged beneath a standing level of liquid in the storage tank. The chamber includes a sealable liquid inlet port communicating with the interior of the storage tank beneath the standing level of liquid. The chamber also includes a liquid outlet port and an aperture that receives compressed air, wherein the compressed air forces a predetermined amount of liquid from the liquid output port of the chamber for use in preparing a brewed beverage. A pump provides the compressed air and a controller monitors a pressure signal value indicative of the air pressure in the metering chamber. The controller commands the pump on to commence flow of the predetermined amount of liquid from the metering chamber. The controller then commands the pump off several seconds after detecting a drop in air pressure within the chamber, indicating that the predetermined amount of liquid has been delivered to the brewing chamber. The chamber is then vented to ambient pressure, which opens the sealable liquid inlet port and refills the chamber.

Patent CA-2299808-A1 (CA)
Inventor: KURZMAN GEORGE
IPC: B63B7/08
Filed: 2000-02-23
Abstract: A rigid, inflatable dory and method for constructing the same. A pre-hull is constructed by attaching to a front end of a rigid, substantially, flat bottom a forwardly inclined stempost and, to a rear end thereof, a rearwardly inclined sternpost, and by attaching left and right garboard plank blanks to the sides of the bottom and to the sides of the stempost and sternpost. The stempost and sternpost are forced toward one another to impart camber and flare to the garboard plank blanks, as by connecting them by a taut rope, thereby converting the blanks into garboard planks. A hull frame is then constructed on the pre-hull, comprising longitudinally spaced apart ribs and laterally spaced apart stringers. A gunwale is attached to an upper edge of each side of the hull frame. An inflatable sponson is mounted exteriorly on each side of the hull. For covering each side of the hull, a water-impervious fabric covering has a lower portion attached to the hull adjacent a garboard plank, an intermediate portion wrapped around a sponson, and an upper portion attached to the hull frame adjacent a gunwale. The method facilitates custom design of dorys as the method requires no plug or jig for forming a hull. The dory is light weight, and the sponsons yield enhanced buoyancy and stability in water, and reduced chance of impact damage to other boats.
