    摘要： A refrigerator is provided that includes an apparatus for producing ice comprising a reservoir that contains water, at least one freezing member, a power source, and at least one fin located on the reservoir. The at least one freezing member is located at least partially in the reservoir. The at least one freezing member is configured for forming ice by freezing the water along the periphery of the at least one freezing member. The power source is configured to move the reservoir to create a movement of the water about the at least one freezing member. The at least one fin located on the reservoir is configured for enhancing the movement of the water about the at least one freezing member and for restricting a splashing of water from the reservoir.

    摘要： An air sampling tube is provided that provides superior air flow, strength, and manufacturability and couples to an air sampling sensor housing. The sidewall of the tubular section has an axially extending groove. To facilitate installation and inspection, an air sampling tube is provided with a starter cap. An end cap prevents air flow through the distal end of the tube. An air sampling tube is provided that assures proper axial positioning of tubular section apertures through resort to a coupler with a rotationally asymmetric joining element. A modular kit is provided that allows for custom installation without resort to cutting or forming operations in the field.

    摘要： A refrigeration appliance includes a storage compartment. An evaporator cools the storage compartment. A defrost heater is associated with the evaporator. A temperature sensor senses an evaporator temperature and generates a temperature signal based on the evaporator temperature. A controller receives the temperature signal and generates a defrost heater power control signal. A power supply receives the defrost heater power control signal and controls a power level supplied to the defrost heater based on the defrost heater power control signal. A first power level is supplied to the defrost heater during a first heating interval of a defrosting operation, and, based on an evaporator temperature rise occurring during the first heating interval, the controller adjusts the defrost heater power control signal such that an adjusted power level is supplied to the defrost heater during a second heating interval of the defrosting operation.

    摘要： A duct detector housing includes a housing cover and a housing body defining a midline between the center of a detector and a printed circuit board within said body. Gas inlet and outlets are off axis of the midline to allow water that collects in conventional housing to drain from the housing. A maintenance mode button associated with a duct detector housing cover that is secured to a housing body of the housing provides a preselected time period during which removal of the cover is independent of a cover removal alarm. A printed circuit board within the housing has dedicated terminal blocks providing grouped connections with each of the groups segregated from another. An improved duct detector terminal has a hole in the terminal adapted to receive a test meter probe therethrough to provide an electrical contact between the wire.
