An icemaker assembly is disposed within a refrigerator having a freezer compartment, a fresh food compartment and respective freezer and fresh food door assemblies. The icemaker assembly comprises a conveyor assembly positioned within the freezer compartment having a flexible conveyor belt with a multiplicity of individual ice cube molds for creation of individual ice cubes. An ice cube storage bin is positioned below the conveyor assembly for storing the ice cubes and a fullness sensor is positioned for determining the fill level of ice cubes within the ice cube storage bin.

Icemaker assembly

Combustion-induced instabilities are minimized in gas turbine combustors by incorporating one or more Helmholtz resonators into the combustor. First and second plates located in the head end of the combustor casing define one cavity, and a sleeve located between the casing and the liner defines another cavity. Each of the two cavities is connected to the combustion chamber by one or more throats, thus forming Helmholtz resonators. The throats of each resonator can be tubes of different lengths and/or different cross-sectional areas to provide dynamics suppression over a broad band of frequencies. The throats can also be arranged such that each throat is associated with a different portion of its respective cavity, each cavity portion having a different volume.

Combustion-induced unsteady oscillations referred to as screech are suppressed in gas turbine combustors by a plurality (preferably two to six) of screech suppression members disposed in the premixers of the combustors. The screech suppression members are attached to the centerbody of the premixer and extend radially outward, nearly into contact with the inner surface of the premixer tube. The screech suppression members are uniformly spaced about the centerbody and are axially positioned at or near the end of the centerbody which is closest to the main combustion chamber. Alternatively, each screech suppression member can be attached to the inner surface of the premixer tube and extend radially inward nearly into contact with the centerbody. Possible shapes of the screech suppression members include a thick block, a thin rectangular plate, a triangular plate, a V-shaped member, and a cylindrical bar.
