  • Patent number: 8074635
    Abstract: The inventions disclosed herein generally relate to isolating heat sensitive components from the heat source of a barbecue grill. In the preferred embodiment, ceramic bushings are used to isolate a glass-reinforced nylon grill stand from the cooking chamber of a barbecue grill. The bushing incorporates a beveled upper edge for engaging with lobes which downwardly depend from the cooking chamber. The bushing also incorporates a circular lower portion for engagement with an aperture in the grill stand. The bushing is locked into engagement with the cooking chamber using a threaded bolt and is locked into loose engagement with the grill stand using a spring clip. The combination of the beveled upper edge and the loose engagement with the grill stand allows the bushing to float with respect to both the grill stand and cooking chamber. As a result, manufacturing tolerance requirements can be relaxed.

  • Patent number: 8074634
    Abstract: An emitter may be positioned for absorbing energy from a burner, and the emitter may include a substantially concave surface for emitting infrared radiant energy so that a substantially uniform distribution of infrared radiant energy is provided at a predetermined plane. The predetermined plane can be referred to as a plane of absorption because, for example, an article for absorbing at least some of the infrared radiant energy may be positioned at the plane of absorption. For example, food can be cooked at the plane of absorption. A support member for supporting the food to be cooked may be proximate the plane of absorption. The support member for supporting the food may be a cooking grid, rotisserie, or other suitable device for supporting the food. In one particular example, the support member is a cooking grid that may be proximate the plane of absorption, or more specifically the cooking grid may be substantially coplanar with the plane of absorption.

  • Patent number: 8047837
    Abstract: Candles are provided for dispensing air treatment chemicals in response to heat. There is a lid bearing the air treatment chemical. The candle includes a housing with a combustible fuel. An upper lid includes a cover plate bearing the air treatment chemical and an opening centrally disposed in the plate to allow heated air to pass through when the fuel is being combusted. The plate is suspended across an upper end of a side wall of the housing creating an air gap adjacent the radial periphery of the lid. When the fuel is combusted the air treatment chemical can be heated thereby and carried away by heated air that has passed through the central opening, and the air gap can permit cooler air to enter the cavity while the fuel is being combusted.
