20080196380 | SHIFT MECHANISM FOR TRIM MOWER CUTTING UNITS - A shift mechanism for trim mower cutting units includes a pair of slidable carriers. Each slidable carrier can slide along a pair of guide rods mounted to a mower frame. A hydraulic extension cylinder is connected to each slidable carrier and independently extends to move the slidable carrier laterally outward from the mower frame or retracts to move the slidable carrier laterally inward in relation to the mower frame. A hydraulic shifting cylinder is mounted between the two extension cylinders and extends to shift both slidable carriers laterally inward toward a center position, and retracts to move both slidable carriers laterally outward toward an extended position. | 08-21-2008 |

20140252908 | STATOR OR ROTOR WITH INTERLACED WIRE GROUPS FORMING AN INTERTWINED WAVE WINDING - The disclosed stator or rotor has a distributed wave winding, in which the wires are associated in pairs lying with straight segments in the same slots. Head portions of two successive straight segments of each wire of a pair protrude from opposite ends of slots. For forming two wire groups, a plurality of coil windings are simultaneously created by winding up n parallel wires with intermediate spacing onto a striplike former that is rotatable about its longitudinal axis. From each of the parallel wires one straight segment and one end turn are doubled by being bent over with the wire length of a head portion, and then head portions are formed and the wires interlaced. Finally, the two wire groups are wound onto one another and thereby intertwined with one another, and then introduced as an entire intertwined wave winding strand into the stator or rotor slots. | 09-11-2014 |

20150145191 | ISOLATORS HAVING NESTED FLEXURE DEVICES AND METHODS FOR THE PRODUCTION THEREOF - Embodiments of an isolator having a nested flexure device are provided, as are embodiments of a nested flexure device and methods for the production thereof. In one embodiment isolator includes an isolator body and a nested flexure device mounted to an end portion of the isolator body. The nested flexure device includes an inner flexure array compliant along first and second perpendicular axes orthogonal to the working axis of the isolator. The nested flexure device further includes an outer flexure array compliant along the first and second perpendicular axes, coupled in series with the inner flexure array, and circumscribing at least a portion of the inner flexure array. | 05-28-2015 |

20110253830 | Reel - A reel comprises a cylindrical core composed of two complementary arcuate core segments, a pair of flanges disposed respectively at axially spaced opposite ends of the core, and a pair of rings for connecting the core to the flanges. The rings are fixed respectively to facing inner sides of the flanges. Cooperating slots and tongues on the rings and core elements prevent the flanges from moving relative to the core in the direction of the axis of the core. The tongues enter the slots when the core segments are brought together. Resiliently bendable locking arms protrude radially inward from both ends of each core segment, and each locking arm is engageable by a snap fit with one of the rings when the core segments are brought together. Access openings in the flanges adjacent each of the locking arms allow access to the locking arms for disengagement from the rings. | 10-20-2011 |

20110006894 | SYSTEM AND METHOD OF MONITORING PERSONAL PROTECTIVE EQUIPMENT - A multi-level equipment configuration monitoring system can include a plurality of RFID tags associated with respective user protective elements such as respirators, eye protectors, gloves boots, helmets and hearing protectors. A user communication unit can activate the tags and determine which elements are present. The determined elements can be compared to a pre-stored, approved list of elements to establish the state of a user's complement of protective equipment. Missing equipment can be immediately identified and brought to the user's attention. Information can be collected as to duration of use of the elements as well as duration of exposure of those elements to one or more predetermined hazardous conditions to schedule maintenance and replacement. | 01-13-2011 |
20150081394 | GENERATION OF COST-PER-BRAKING EVENT VALUES - Systems and techniques are described for generating cost values for a plurality of braking events of an aircraft, where each cost value is based on an expected wear of the wheel-and-brake assembly of the aircraft during the respective braking event. The systems and techniques may take into account data representative of conditions during the respective braking event of the aircraft to generate the cost values. | 03-19-2015 |
