Abstract: A cooling apparatus for cooling a switchgear is provided. The switchgear has one or more primary contacts supported by a bushing and constructed and arranged to connect to a terminal of a circuit breaker. The cooling apparatus includes at least one evaporator associated with each primary contact, a condenser apparatus located at a higher elevation than the at least one evaporator, fluid conduit structure connecting the at least one evaporator with the condenser apparatus, and electrically insulating working fluid in at least one evaporator so as to be heated to a vapor state, with the fluid conduit structure being constructed and arranged to transfer the vapor to the condenser apparatus and to passively return condensed working fluid back to the at least one evaporator.

Abstract: A sewer flushing apparatus includes means for providing a predetermined, intermittent flow of water into a sewer line (28) including timing means (20) for controlling a valve mechanism (18) to effect the intermittent flow. Means (34) are also provided to shut the system off in response to high fluid levels in the sewer line.
