| A water pressure system includes a pressure tank installed underground within the well casing of a well. The water pressure system includes a submersible pump connected to the inlet of the pressure tank by a drop pipe. The outlet of the pressure tank is connected to a second drop pipe and in turn to a discharge pipe for distribution of pressurized water to a house or other building. A pressure switch is connected to the pressure tank for controlling the submersible pump. The pressure tank includes an outer sidewall with an inlet end and an outlet end. A flexible diaphragm bladder located within the outer sidewall is connected between the inlet and outlet of the tank. In a first embodiment, a tube extends through the center of the bladder between an inlet opening and an outlet opening. The tube has a plurality of holes therein to allow water to flow into and out of the flexible bladder. Pressurized air fills the space between the bladder and the outer sidewall to pressurize the water in the bladder. The pressure tank may be used in combination with a flow control valve, a relief valve, a flow control valve incorporating a relief valve, a standard submersible pump, and/or a variable speed submersible pump to provide and maintain a constant flow of water at a constant pressure through the system. | ||||||

| 188 | Pitless adapter assembly | US09505032 | 2000-02-16 | US06311770B1 | 2001-11-06 | Jerry D. Mullis |
| A pitless adapter assembly for a water well system or the like operable by a pump suspended in the well below the pitless adapter assembly to pump underground water upwardly through a plastic supply pipe to a feed pipe through a fitting in a well casing, and including a housing having a generally right-angle flow path therein defined by an housing inlet and a housing outlet for interconnecting the supply pipe with the feed pipe through the well casing. The housing includes an integrally-formed eyelet for receiving and retaining a safety cable to which the pump is suspended in the well and a plurality of annular serrations formed in the walls of the housing surrounding the housing inlet for receiving and retaining an upper end of the feed pipe. Interior walls of the housing defining the flow path extend between the housing inlet and the housing outlet and are curved to provide right-angle turn which reduces turbulence in the water flowing through the housing from the supply pipe to the feed pipe. | ||||||
| 189 | Method and apparatus for controlling the flow of crude oil from the earth | US682644 | 1991-04-09 | US5146987A | 1992-09-15 | Ronald K. Krieg |
| A method and system for stopping the flow of petroleum from a location along a pipe extending from an underground petroleum deposit, when the location is at, below, or above the surface of the earth. Initially, the location is identified of at least one underground segment of the pipe between the deposit and said location along the pipe. Then, a fluid flow path is established from at least one point on the surface of the earth displaced from the identified point along the pipe to the underground region adjacent to at least one of the underground segments. A flow of a coolant is established in or along the fluid flow path and that flow is controlled whereby sufficient heat is extracted from the underground segment, in effect lowering the temperature of the flowing oil, so that the flow rate of petroleum flowing through the segment is reduced substantially to zero. The blockage may be removed by heating frozen oil in the segment so that flow of oil may be re-established in the well pipe. | ||||||
| 190 | Well cap | US21215 | 1987-03-03 | US4715439A | 1987-12-29 | Roy E. Fleming |
| A covering is provided for the upper extremity of a circular cylindrical casing wall of a well for potable water.

The upper manifold includes a single inlet for receiving water from the bypass tube and an outlet for discharging water to a pipe connecting the bypass to a frost free hydrant at the top end of the well casing. | ||||||
| 193 | Method of manufacturing a pitless adapter | US553198 | 1983-11-18 | US4531664A | 1985-07-30 | Henry A. Baski |
| A generally uniform diameter elongated barrel unit secured to the top of a well casing which provides a seat for a spool unit having spaced plates defining a flow directing central space to a lateral distributing pipe. The plates have peripheral sealing means engaging sealing rings of stainless steel material on the inside of the barrel unit. The apparatus may be arranged for use with either a turbine drive type pump having a ground level motor or a submersible pump. The spool unit is inserted into and may be withdrawn from the barrel unit by axial movement. A heavy flange is welded to the top of the barrel unit to provide a heavy duty work platform and motor mount or support for a cover. | ||||||
| 194 | Gasketless well casing cap | US477092 | 1983-03-21 | US4457448A | 1984-07-03 | Joseph L. Beagell |
| A cap assembly for sealing engagement with the upper end of a cylindrical steel well casing is provided in two initially separate, upper and lower sections. The lower section has a major opening therethrough for encircling the upper end of the well casing, the diameter of said opening tapering from a dimension at the lower side which is slightly larger than the diameter of the casing, to a slightly smaller diameter at the upper side. The material of the cap and dimensions of the major opening relative to the outside diameter of the well casing are such that the lower section may be manually inserted on the casing, with the latter extending completely through the major opening, whereby the lower section is in tightly sealing engagement with the casing without requiring a gasket. The upper cap section provides a cover for the lower section and includes a recessed portion bounded by a lip of continuous, closed outline extending downwardly from the lower surface of the upper section. After the lower section is engaged with the casing, the upper section is bolted thereto with the upper section lip engaging, and preferably slightly embedded in the upper surface of the lower section to seal the opening therein, and thus the end of the well casing. | ||||||
| 195 | Method for gas capping of idle geothermal steam wells | US328195 | 1981-12-07 | US4407366A | 1983-10-04 | William C. Lieffers; Marjorie M. Hatter |
| A method for capping an idle geothermal steam well so as to prevent hydrogen sulfide emissions and well damage due to steam condensation includes replacing geothermal steam in a well borehole with gas, perferably an inert gas such as nitrogen, and sealing the well at the wellhead. Thereafter additional quantities of the gas are bled into the well borehole at a rate that substantially prevents steam condensation in the borehole. The method includes purging the well bore with air sufficiently to assure all steam is swept out of the well before the gas is introduced. | ||||||
| 196 | Well casing closure | US149017 | 1980-05-12 | US4334578A | 1982-06-15 | Warren W. Labrum |
| This invention is a well casing closure for closing and covering the top of a well casing extending above the surface of the ground. The invention is characterized by comprising a hollow cylindrical member closed on one end and open on the other end of such dimension as to fit over the top of the well casing and to provide a reasonably snug fit about the exterior of the casing; it is further characterized by utilizing an "O" ring or the like, for sealing between the interior of the closure and the exterior of the casing; additionally, a locking mechanism is incorporated so that the closure may be locked in place over the opening and only removed by one having a key to the lock. | ||||||
| 197 | Pitless connection incorporating pressure relief valve | US90739 | 1979-11-02 | US4308916A | 1982-01-05 | Richard R. Fritz, Jr. |
| This invention is a pitless water well adapter which incorporates a pressure relief valve in such manner that in the event the pressure relief valve is activated it discharges directly back into the well and down the well casing rather than exterior in a different part of the system as has been customary. The invention is characterized by a pitless adapter wherein the pitless adapter has been modified so as to incorporate a pressure relief valve having an opening from which water will discharge directly within the well casing. | ||||||
