Abstract: A protective device for electrical power distribution equipment includes a removable fuse holder and an integral load switch. The protective device may be affixed to a grounded metal enclosure, such as an oil-filled transformer, into which the protective device extends. The fuse holder may be removed from the protective device for checking or replacement with a minimal opening into the enclosure into which the protective device extends. A suitable load switch actuator is provided for controlling current flow through a fuse in the fuse holder. This load switch actuator also provides an interlock arrangement to prevent removal of the fuse holder from, as well as insertion of the fuse holder into, the protective device unless the load switch is open, thus ensuring that interruption and initation of current flow through the fuse in the removable fuse holder is controlled by the load switch.

Abstract: Apparatus for selectively stacking, or inverting and stacking, sheets moving seriatim along a travel path with a given facial orientation. The apparatus comprises a sheet supporting surface for supporting and stacking sheets in a facial orientation effectively reversed from that of such sheets in the travel path, and a guide selectively movable to a first position along the travel path or a second position in the travel path. In the first position, the guide directs sheets onto the supporting surface; while in the second position the guide itself receives and stacks the sheets, remote from the supporting surface, in a facial orientation the same as that of such sheets in the travel path.

Abstract: An electrical loadbreak fuse and canister assembly with arc quenching means operative upon withdrawal of the fuse from the canister or upon insertion of the fuse in the canister under either load or fault conditions. The canister, formed of a glass filled polyester tube, is designed to extend within the enclosure for an electrical device to be protected by the assembly, and is provided with a flange at the outer end for mounting on the enclosure. A fixed loadbreak contact at the inner end of the canister is enclosed within a non-conductive sleeve having a collar formed there around. The inner end of the fuse is provided with a loadbreak contact probe having a non-conductive tip and with a non-conductive disc mounted between the fuse and the contact probe. Both the sleeve and collar, and the disc serve to defuse and cool ionized gases generated by arcing between the loadbreak contacts within the canister.
