Abstract: A dispenser for controlling the release of volatile materials within a contained environment such as an automobile, a home, an office, a factory, or the like, comprises a housing having an opening therein, a volatile material positioned within the housing, and a temperature responsive component in operable association with the opening to regulate said opening in order to contain or release the volatile material. The temperature responsive component automatically controls the release of the volatile material in the contained environment in response to a change in the ambient temperature by uncovering or covering the opening of the housing. A method for controlling the release of volatile materials within a contained environment is also disclosed.

Abstract: Candles are disclosed that include a wick, a first phase and a second phase. In one embodiment, the first phase is substantially clear and has a first melting point, the second phase is visually distinct from the first phase and has a second melting point, and the second melting point is greater than or about equal to the first melting point. In another embodiment, the first phase contains a first concentration of gellant in first solvent, the second phase contains a second concentration of gellant in second solvent, and the first and second concentrations are non-identical. In another embodiment, the first and second phases each contain gellant, however the second phase contains components not present in the first phase.

Abstract: An air seal is illustrated as used in a gas turbine engine. The seal includes at least a seal substrate, a relatively dense, erosion resistant ceramic layer applied over the bond coat, and an abradable ceramic layer applied in a local area over the dense ceramic layer. The abradable ceramic interacts with a component moving relative to the seal, such as a turbine blade that moves relative to the seal, and cooperates with the moving component to provide sealing and thermal insulation.

Abstract: A computer-aided design system includes a method and apparatus for defining various datums with respect to a three dimensional object shown on the CAD system. The datum is labeled on the computer screen. The computer screen includes a cursor and menus for selecting a datum and various tolerance types with respect to the datum or a face related to the datum. A tolerance type and numerical value is selected for the tolerance and is also displayed on the screen. A geometric element from the CAD model or object displayed is selected to which the tolerance applies to the selected element. Data relating to the tolerance data, the geometric element, and the datum are stored within the computer. Linkage relationships are used to relate the data stored.
