摘要： A metal strip is continuously cast between a pair of heat conductive endless belts which serve to form a molding zone to solidify molten metal. The endless belts remove heat from the molten metal and are cooled when the belts are not in contact with the molten metal, which minimizes belt distortion.

摘要： The present invention is a process to use aluminum alloy scrap to manufacture high quality machinable tooling plate. This is an new use for this scrap which has heretofore been used in lower quality products. The tooling plate thus made has superior properties when machined as it produces smaller chips and/or a limited of spirals from the plate. Large chips and long spirals create problems and a smaller chip greatly facilitates the machining operation.

摘要： A system and a process is provided for reducing the dust formation during the transfer of a particulate material on an endless conveyor belt. During transfer of the material on the conveyor belt the material is first sprayed with a wetting agent then by application of a plow the moving material is lifted from the bottom of the belt and is diverted towards the side edges of the belt thus creating additional exposed surfaces. The material is then again sprayed then contacted with baffles to redirect the material from the side edges towards the center of the belt thus creating additional exposed surfaces which are then again sprayed with a wetting agent to substantially eliminate dusting. The plow and baffle combination can also be used for uniformly mixing two or more particulate materials on a moving belt.

摘要： A canister for an airbag inflator includes a tubular body having a cylindrical shape elongated from a first end to a second end along a longitudinal central The tubular body forms a continuous wall that defines a pressurized gas chamber at the first end and a diffuser at the second end. The continuous wall is spaced from the central axis by an approximately constant radial distance from the first end to the second end. The canister also includes a burst disk integrally formed with the body from a single piece of material (e.g., aluminum alloy). The burst disk is oriented transverse to the central axis to separate the pressurized gas chamber from the diffuser. The burst disk has a thickness less than that of the body wall. Because the burst disk and wall are formed of the same material according to these relative thicknesses, the burst disk will rupture before the structural integrity of the wall is compromised. A score pattern can be imprinted on the burst disk to facilitate uniform failure during activation of the inflator.
