Abstract: A miniaturized, light-weight load sensing transmission which inputs an external rotation and outputs a high or low speed, depending on the sensed load, and in which there is no neutral state position when rotation speed is switched, thereby providing safe, secure and smooth speed switching; and a hoisting machine including the load sensing transmission. The load sensing transmission (11) includes: a variable speed mechanism to transmit the input external rotation as a high speed without changing the speed or as a low speed after decelerating the speed; and a load sensing mechanism (22) to sense a high or low load of an output side of the variable speed mechanism, to switch an output rotation of the variable speed mechanism to a low or high speed state by engaging with or disengaging from the variable speed mechanism.

Abstract: A grade level enclosure conversion assembly adapted for converting a pedestal housing between a flush-to-grade and an above-ground pedestal installation. The base of the pedestal housing carries a plug removably mounted to a swing-arm in the grade level enclosure. The swing-arm holds the pedestal assembly in a stored position in the flush-to-grade installation, containing wiring for service connections. To convert to the above-ground installation, a solid grade level cover plate lid is removed, and the pedestal assembly is rotated on the swing arm to a raised position from which it can be removed from the swing- arm (along with the wiring) and fed through an access opening in a separate cover plate lid. The plug on the pedestal housing is then positioned in the access opening to hold the pedestal assembly in the above-ground position. A series of separate fiber optic splice connections, or other underground utility service connections, can be made when rotating the pedestal between the stored position and the above-ground position.

Title: Apparatus for excluding particle contaminants from a gas lift off mechanical seal
Inventor: GRIFFITH DARYL L
IPC: F16J15/16
Filed: 2015-08-14
Granted: 2019-09-17
Abstract: A particulate exclusion mechanism for a gas lift off seal includes a band fixed to the stationary seal face and extending over the lift off region between the stationary and rotating seal faces, thereby forming an annular cavity surrounding the lift off region that traps barrier gas therein as it leaks through the lift off region and inhibits process fluid from entering the annular cavity and reaching the lift off region. The band can be made of a non-abrasive material such as PTFE or PEEK. The band can extend over the rotating seal face, and a portion of the band can be sufficiently flexible to allow the extended end of the band to constrict in diameter and contact the rotating seal face if the process pressure exceeds the barrier gas pressure. The extended end can include a thicker terminating portion that minimizes clearance with the rotating seal face.
