摘要： High voltage fuses are mounted on individual carriers for movement into and out of engagement with stationary contacts under the control of a carriage that can be connected to any or all of the carriers. Switches are arranged to connect any or all of the fuses in circuits. A locking bolt holds each fuse carrier in closed position and can be moved to locking position only when the fuse carrier is closed. Interlocks between the fuse carriers and operators for the switches prevent opening the carrier when the switches are closed and closure of the switches when the carriers are open.

摘要： After initial arc drawing movement the rodlike terminal of a high-voltage alternating-current power fuse driven by a spring and gas pressure has its speed reduced by encountering a damper body which is normally latched in a stationary position until it is unlatched on impact by the terminal. A cross-slide latch is employed to hold the damper body stationary in a fuse housing for release on impact by the terminal.

摘要： Metallic housing for pad-mounted high voltage switches and fuses has sliding top panel which must be shifted forward or back to permit removal of back and front sliding access panels. A lock prevents movement of the top panel from overlying relation to the front and rear panels. Fuses are mounted in a drawer which is locked closed and can only be opened when the lock under the top panel is uncovered. Access to the manual operator for the switch assembly or assemblies is accessible only when the top panel is shifted back. A mechanical maze construction between exposed movable panels reduces likelihood of entrance of wire and the like.

摘要： For distribution of electric power metal enclosed drawer-mounted fuses are provided having manually operated switches commonly connecting them to a loop feeder circuit. Manually operated grounding switches connect the switch contacts to ground. Interlocks prevent opening of the fuse drawer when the loop feeder switches are closed, closure of the loop feeder switches when the fuse drawer is open, grounding of the switch contacts when the loop feeder switches are closed, and closure of the loop feeder switches when the switch contacts are grounded.

摘要： A radio receiver adjusts its center frequency according to the center frequency differential between the receiver and associated transmitter, maintains the correction for a time after transmission ceases, opens the circuit to the load driven by the receiver and grounds the load circuit.
