Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

Abstract: A block fitting assembly comprises a first block having a first fastener aperture formed therethrough, a second block having a second fastener aperture formed therethrough in axial alignment with the first fastener aperture, and a fastener extending through the first fastener aperture and the second fastener aperture to couple the first block to the second block. The block fitting assembly includes a thermal expansion compliancy feature in the form of at least one of an inner surface of the second block defining the second fastener aperture including an axially extending non-threaded portion adjacent a threaded portion thereof or the fastener including a necked portion having a smaller outer diameter than a minor thread diameter of a threaded portion of the fastener.

Abstract: Provided are a method, system, and article of manufacture for specifying user defined or translator definitions to use to interpret mnemonics in a computer program. A mnemonic is processed in the computer program having a user defined definition and a translator definition. The mnemonic is interpreted according to the user defined definition in response to previously processing a mnemonic command specifying the mnemonic and the user defined definition. The mnemonic is interpreted according to the translator definition in response to previously processing a mnemonic command specifying the mnemonic and the translator definition.

Abstract: A work machine includes a frame supported for movement over the ground, a prime mover for driving movement of the frame, an operator compartment supported on the frame and a cradle coupling the operator compartment to the frame. The cradle is pivotable between an operating position and a service position and includes a biasing mechanism for biasing cradle toward the service position and an isolation mount coupling the operator compartment to the cradle. The isolation mount permits deflection of the operator compartment relative to the cradle along a selected axis. A latch mechanism releasably couples the cradle to the frame and a handle is provided for actuating the latch mechanism. The isolation mount includes a deformable member having a void defining the selected axis. The axis can be aligned with a force exerted on the cradle by the operator compartment to reduce stress on the biasing member.

Abstract: A track frame or undercarriage is made to support a rubber track on suitable guide rollers. A tensioning roller is provided as one of the guide rollers on the interior of the track and is mounted on a pivoting bracket. The pivoting bracket moves the tensioning roller to a working position for creating tension in the track. An actuator provides a known force on the pivoting bracket to move the tensioning roller to its working position, using a controlled pressure applied to the actuator. Drive sprockets for the track are mounted onto a drive case that is mounted to the frame through pivoting linkages such that the drive case and the drive sprocket can be held in a working position and retracted away from the track. The position of the tensioning roller is maintained within set limits of retractions during use, by providing a stop to limit the amount that the tensioning roller can retract.

Abstract: A track driven machine has a pair of track frames on opposite sides thereof, and each of the track frames has a pair of laterally extending arms fixed thereto. The arms are joined to a machine frame only through vibration isolating elastomeric blocks that carry compression loads from the arms to the machine frame. The elastomeric blocks are held in place with bolts that pass through openings in the machine frame. There are second elastomeric blocks above each of the first blocks to support downward movement of the arms relative to the machine frame.

Abstract: A drive track for a tracked vehicle has drive lugs on the interior side that are made in two rows, one row adjacent each of the lateral sides of the track and spaced apart on opposite sides of the longitudinal center plane of the track. The first row has lugs spaced a selected distance on center, and the second row lugs are spaced the same distance but offset one-half of the distance between the lugs in the first row along the length of the track. A drive sprocket or wheel has two sections, each with drive bars that are annularly offset from the other the same amount as the track lugs so that the rows of track lugs are driven by the drive wheel sections.
