Patent number: 9912127Abstract: A switchgear cabinet (100) includes an equipment compartment (102), a bus compartment (104) and a cable compartment (106). The cabinet can employ a sensor(s) (190) to monitor conditions, such as arcing, in the bus or cable compartment. The cabinet also includes a retractable sensor system (150), which has a rack (160) and a slider (170). The rack is mounted in the cabinet, and the slider is configured to retain the sensor. The slider is movably engaged to the rack. The slider can slide in one direction toward a back of the bus or cable compartment to a racked-in position in which the sensor is located to sense arcing in the bus or cable compartment. The slider can slide in an opposite direction toward a front of the equipment compartment to a racked-out position in which the sensor is drawn into the equipment compartment.Type: GrantFiled: December 5, 2013Date of Patent: March 6, 2018Assignee: Schneider Electric USA, Inc.Inventors: Mark J.

Patent number: 5303643Abstract: A waste container crusher particularly adapted for crushing automotive type oil filters or other structurally rigid disposables containing hazardous waste has a housing with an open bottom which is closed off by an anvil plate. The anvil plate slideably receives three equiangularly spaced posts which are secured to a roof plate at the top of the housing, above the anvil plate. Nuts on the posts support the anvil plate below the roof plate, so that the anvil plate is suspended from the roof plate by the posts. The roof plate is secured to a hydraulic cylinder which produces a 10 ton driving force for a platen guided by the posts to crush a container placed on the anvil plate below the platen. In the anvil plate, four blind bores in a rectangular pattern in the top surface intersect a central blind bore extending from the bottom surface, and a smaller central through-bore provides communication between the lower central blind bore and the top of the anvil plate.Type: GrantFiled: January 21, 1993Date of Patent: April 19, 1994Assignee: Applied Power Inc.Inventors: Mark J. Fisher, Edward T. Arters
