Abstract: A haul truck dump tray with a pneumatic shock absorption system is provided. The haul truck dump tray includes a first longitudinal body portion and a second longitudinal body portion joined along a center line by an interposing elastomeric link extending along the center line and bonded to and between them. The haul truck dump tray includes a topside support member joined along the center line by the interposing elastomeric link to the first longitudinal body portion and the second longitudinal body portion. The haul truck dump tray includes a bottomside support member joined along the center line by the interposing elastomeric link to the first longitudinal body portion and the second longitudinal body portion. The resulting haul truck dump tray has improved weight, strength, and durability characteristics.

Abstract: An energy-dissipative pneumatic cushioning system for cushioning heavy loads includes (i) one or more support members that extend beneath at least a portion of at least one pneumatic cushioning element and (ii) at least one connector assembly that communicatively couple the at least one pneumatic cushioning element to a gas supply unit and optionally at least one gas reservoir. The at least one gas reservoir is capable of accepting at least a portion of gas from the at least one pneumatic cushioning element under a force of a load. The at least one connector assembly is further operable to allow a return of at least a portion of the gas to the at least one pneumatic cushioning element upon reduction of at least a portion of the force of the load.

Abstract: A printed circuit board for use with a cooling device configured to cool at least one device is provided. The printed circuit board includes a substrate having a first surface and a second surface opposing the first surface; a ground plane on the first surface of the substrate, and circuitry in a circuit-region on the second surface of the substrate. The ground plane includes a patterned-region that is patterned with an array of holes. The circuitry is configured for use with the at least one device to be cooled. When a first side of the cooling device contacts the ground plane, and when the at least one device to be cooled contacts the circuitry, a reduced cross-sectional area of the patterned-region prevents heat from a second side of the cooling device from degrading performance of the at least one device.

Abstract: The present invention provides a high-performance helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by connecting conductive plates to the windings of the antenna elements at the terminal ends thereof such that the conductive plates are offset from the axes of the antenna elements and toward the center of the array.

Abstract: A wellhead assembly including a towable oil lift system, a drum, a wireline spooled on the drum, and a level wind mechanism is set forth to extend the wireline into and out of a well casing for production of a well. The wireline spools over a measuring wheel and extends into the well and supports a bailer on the end of the wireline. The bailer has a foot valve for filling, thereby enabling retrieval of a bailer into a surface located seal assembly connected with an air pump to force liquid from the bailer. A control system enables cyclic operation.
