  • Publication number: 20070095074
    Abstract: An acoustic cooling device is provided. A coldhead and an acoustic power source of the acoustic cooling device are separated by way of a long tube connecting them to enable the cold tip to be installed in a remote location where a traditional unitary system would not fit, would generate too much vibration, or would be otherwise undesirable. The dimensions of the tube and the relevant parameters of the acoustic power source are selected to keep the system resonant at the desired drive frequency (e.g., 60 Hz) and to minimize the impact of the long tube on the system efficiency and capacity.

  • Publication number: 20050199353
    Abstract: A cord-operated window covering is provided with means for equalizing the individual lift cord lengths to maintain a horizontal and level bottom rail, while avoiding the choking danger to small children presented by exposed cord loops that can become entangled with the child. A break-away coupling of the exposed cord ends is provided in the form of a shear-loaded, separable joint that is strong when subjected to shear-type forces in normal use, but which is weak when loaded in peel or tension perpendicular to the joint, as would occur in a potentially dangerous child-entangled situation. The joint is formed by surface-modifying products applied to the opposed abutting surfaces of the individual cordlock members. Also disclosed is an embodiment that utilizes a continuous lift cord loop that is frictionally gripped by a gripper member secured to the shade.

  • Patent number: 6739136
    Abstract: A combustion system for a hybrid solar receiver comprises a pre-mixer which combines air and fuel to form an air-fuel mixture. The mixture is introduced tangentially into a cooling jacket. A burner plenum is fluidically connected to the cooling jacket such that the burner plenum and the cooling jacket are arranged in thermal contact with one another. The air-fuel mixture flows through the cooling jacket cooling the burner plenum to reduce pre-ignition of the air-fuel mixture in the burner plenum. A combustion chamber is operatively associated with and open to the burner plenum to receive the air-fuel mixture from the burner plenum. An igniter is operatively positioned in the combustion chamber to combust the air-fuel mixture, releasing heat. A recuperator is operatively associated with the burner plenum and the combustion chamber and pre-heats the air-fuel mixture in the burner plenum with heat from the combustion chamber.
