The fan comprises a plurality of fan blades that define a fan diameter and a BEAL. The fan case comprises an inlet and an inlet length between the inlet and the fan. The acoustic spacing comprises a distance between the fan and the plurality of outlet guide vanes, and in combination with the BEAL determines an acoustic spacing ratio of the gas turbine engine.

Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A device for receiving and organizing twisted pairs of conductors from a cable having a plurality of twisted pairs of conductors includes a block with upper and lower surfaces, first and second opposing end walls that define a longitudinal axis, and first and second opposing side walls. The block further comprises at least one aperture extending from the upper surface toward the lower surface, the aperture being sized and configured to receive each of the plurality of twisted pairs of a cable. Each of the side walls includes at least one open-ended slot opening downwardly, each of the slots being sized and configured to receive a respective twisted pair of conductors. In this configuration, the device can facilitate termination of twisted pair conductors onto IDCs or the like and can provide a termination with less dimensional variation (and, in turn, less variation in electrical performance) than prior termination devices.

Abstract: An improved storage compartment for batteries and the like is formed by a housing and a compartment door. The housing includes an opening along one edge that is shaped to receive the compartment door. Within the opening are circular supports for holding the compartment door and for permitting rotation of the door into the housing as it is being opened. The compartment door contains a cylindrical shaft at each end thereof for engaging the circular support. When used as a battery compartment, metallic contacts are either mounted in the housing or in the door itself. These contacts make electrical connection with one or more batteries placed into the storage compartment. Within the compartment, batteries are positioned such that the axis around which the compartment door rotates passes through the center of gravity of the batteries.

Abstract: The present invention encompasses a method for enumerating microbial cells in an aqueous test sample comprising: fluorescently labeling the microbial cells in test sample intermixing a known amount of monodispersed fluorescently labeled beads of about cell size into the test sample, and determining the ratio of bacterial cells to fluorescently labeled beads, the reagents for practicing this method. The methods and reagents of the present invention are particularly useful in counting bacterial cells in urine.
