Abstract: A firefighting method and apparatus are described for suppressing fires in remote dried out former wetlands/marsh areas. A water pump is positioned upon a floating platform maneuverable in adjacent shallow marsh waters that are not navigable by conventional watercraft. Said pump has an intake port for drawing water from nearby marsh waters and ponds through a hose, said hose having a filtering screen for preventing the pickup of solid materials. The pump has a discharge hose connected to the outflow connection, said discharge hose connected on the distal end to a piping extension projecting away from the hull and over the nearby burning peat lands. Said pump is operated to discharge water over and into the adjacent burning marsh as the platform is maneuvered within the surrounding marsh canals and waterways.

Abstract: This design addresses the problems in areas below sea level adjacent to coastal communities with shallow canals/inlets with high tides/surges entering the discharge piping outlets arranged for normal average mean sea levels from pumping stations with outflow into a reservoir/body i.e., lake, river or waterway that is affected during storms, hurricanes or heavy rains driven by winds and high tides that render pumping inefficient at least and/or inoperable at worst. Included in this design is an inlet of a manifold connected to the pump's discharge, a normal discharge outlet and a second optional bypass discharge piping outlet, elevated over or through a high wall. Also included is automatic/manual shutoff valves and variable speed drive motor. The bypass discharge outlet includes, prior to the distal end, an ancillary piping arrangement that allows portions of the discharge flow directed back into underground aquifers for water table replenishment to aid subsidence maintenance.

Abstract: This design addresses the problems of high tide/surges entering the discharge outlets of piping from pumping stations that discharge into a reservoir/body i.e., lake, river or waterway that is affected during storms, hurricanes or heavy rains driven by high tides and wind, that render pumping inefficient at least and inoperable at worst. This is a bypass system of piping into a manifold header that includes an inlet from the pump's discharge pipe, a discharge outlet and a second optional discharge—by pass outlet. It also includes optional automatic shut off valves in the piping scheme and variable speed drives on the pump motors. The by pass discharge outlet piping also includes an ancillary piping arrangement that allows portions of the discharge flow to be directed back into underground aquifers to replenish the diminishing water table level that contributes to subsidence. This system is subject to many possible modifications.

Abstract: Two embodiments (FIGS. 1+ & FIGS. 5+) of a double, by-pass valve system for a closed refrigerant system allowing its safe servicing, the first being included in the original manufacturing of the compressor unit in the refrigerant exit line of the compressor (FIG. 4 ) and the second installed as a retro-fit on the compressor unit and provided "in-line" in the liquid refrigerant line. In the first a double valve body with a transverse bore through a main shut-off valve allows the flow of refrigerant to pass or be shut down to the rest of the system, while a secondary, access port with a transverse bore intersects the main flow valve on the upstream side of the seats by means of a manifold bore, providing a by-pass passageway to an access connection (minus a depressible valve core or "Schrader" valve) for a refrigerant hose to connect to the manifold charging gauges, allowing communication with the closed refrigerant system.

Abstract: A device for servicing closed refrigerating systems comprising a double valve body with a transverse bore through a main shut off valve. The invention disclosed herein consist of methods for entering a closed refrigeration system for testing, charging and exiting the system, vacuum processes to vacuum the entire system and either the high or low sides of the system simultaneously and a method for the storage. The disclosed device and process eliminates a great percent of the loss of refrigerant in the refrigerant hoses when disconnecting during servicing and repairing the high side while using the recommended service techniques.
