Abstract: A flexible metal disk used to mount the fan to the fan drive.

Abstract: A multi-shot injection mold utilizes a minimum of a first shot cavity and a second shot cavity for receiving injected molded plastic to produce a completed multi-component product. In conventional two shot molding, the injection of molten resin, cooling time of such resin, transportation of product to subsequent position and ejection of completed product requires a restrictive sequence.

The invention uses a three position/station concept which allows each position to act independently of each other. The independent positions allow injection of first shot, injection of second shot and ejection of finished product to occur simultaneously. This effectively removes any additional cycle time required for ejection in the molding cycle.

Abstract: Multi-stage combustion technology combined with nitrogen-enriched air technology for controlling the combustion temperature and products to extend the maintenance and lifetime cycles of materials in contact with combustion products and to reduce pollutants while maintaining relatively high combustion and thermal cycle efficiencies. The first stage of combustion operates fuel rich where most of the heat of combustion is released by burning it with nitrogen-enriched air. Part of the energy in the combustion gases is used to perform work or to provide heat. The cooled combustion gases are reheated by additional stages of combustion until the last stage is at or near stoichiometric conditions. Additional energy is extracted from each stage to result in relatively high thermal cycle efficiency. The air is enriched with nitrogen using air separation technologies such as diffusion, permeable membrane, absorption, and cryogenics.
