Abstract: A system for increasing production of oil from subterranean formations comprising placement of heat or steam into the reservoir via radial drainage tunnels. The heat or steam may be created in the wellbore near the top of the well, downhole in the wellbore, or in-situ in the radials positioned in the reservoir.

Abstract: A downhole apparatus for cutting casing and rock when radial drilling defined by a cutting head that includes three or more cutting edges positioned around the cutting head's axis of rotation, at least three of the cutting edges in continuous contact with the face of the material being cut, thereby providing lateral and angular stability to the cutting head, one or more internal fluid passageway within the cutting head and one or more orifices for ejecting drilling-fluid out of the cutting head.

Abstract: Methods and apparatus are disclosed to overcome problem that are encountered when using coiled-tubing to deploy radial drilling tools in certain wells. In addition, this disclosure provides means and tools by which radial drilling tools can be conveyed and powered by slickline or e-line. To advance the radial drilling tools and/or to apply and control weight on bit (WOB), a chamber is created and is then pressurized to generate a piston-affect. Furthermore, tools and methods are provided to monitor the radial drilling tools' operations and to convey this information to surface personnel. In addition, because the e-line, slickline and certain coiled-tubing strings lack adequate torsional stiffness, torque arresting mechanisms are disclosed. This disclosure further provides for a “zero-discharge drilling” system, a “drill-by-wire” system, and enables radial drilling solutions in horizontal wells using coiled-tubing, e-line or slickline.

Abstract: The present invention is a crankcase heater for preventing the migration of liquid refrigerant. The heater is located on the compressor housing surface near the oil sump. The heater is positioned within a fence of a terminal assembly, covering substantially all the surface area enclosed by the fence except for the terminal cluster itself. The heater provides heat to the housing and the interior of the compressor, and the gasket insulates the heater and interiorly reflects the heat produced. Liquid refrigerant in the oil sump is boiled off to increase the pressure inside the housing and inhibit migration of refrigerant from the evaporator or accumulator.

Abstract: The invention is a wellhead stuffing box leak detector including a split-ring adapter which is installed between the stuffing box and the stuffing box cover. The leak detector functions to contain liquids which leak out of the well through the stuffing box and diverts the leakage via an overflow tube to a clear fluid reservoir. The fluid reservoir is provided with a float that moves upward when the fluid level in the fluid reservoir rises, thus activating a switch which can be used to trigger an alarm or to turn motors or engines on or off.

Abstract: A microwave signal detector system provides a visual indication of the relative bearing of a remote source of microwave energy. An antenna for receiving said microwave energy includes a plurality of microwave-sensitive elements arranged in a planar circular array for receiving pulses from all azimuth directions. Each microwave sensing element is adapted to monitor energy received in a predetermined angular sectors and includes a horn element and a microwave energy responsive diode disposed within said horn element. The diode is connected as part of a voltage divider to develop a noise signal corresponding to the microwave energy received at each sector resulting from vibrations in the diode which occur at an audio frequency. The resultant developed noise signal is digitized and compared to a predetermined threshold to provide an output control signal when the developed signal exceeds the value of the threshold. The output signal drives an LED indicator.

Abstract: A suction accumulator for the compressor of a refrigeration system including a disk-shaped dirt trap baffle member spaced from the wall of the vessel to form a gap through which liquid refrigerant flows from an active zone above the baffle to a quiet zone therebelow. Within the quiet zone, liquid refrigerant flows from a radially outer region to a radially inner region along a tortuous flow path. A bleed-through orifice in a gaseous refrigerant flow conduit siphons liquid refrigerant from the radially inner region into the gaseous flow path. Foreign particles suspended in the liquid refrigerant are isolated within the accumulator at various points along the flow path, particularly within the quiet zone. A cup-shaped porous filter is disposed over the lower end of the conduit for the gaseous refrigerant to filter liquid refrigerant before it flows through the orifice.

Abstract: A pressure relief valve for a hermetically sealed reciprocating piston compressor is made in which a bore in a compressor cylinder head defines the valve body. Valve components are introduced into the bore through a valve opening on the bottom surface of the cylinder head. A discharge pressure chamber in the cylinder head also has a discharge pressure opening on the bottom surface. A path is provided between the valve opening and the discharge pressure opening, when the compressor is assembled, by means of a duct in a valve plate interposed between the cylinder head and a compressor crankcase. Also disclosed is a method for assembling the pressure relief valve in a cylinder head, whereby the valve components are temporarily retained within the bore by a washer-shaped soft metal valve seat that is compressed and expanded into an annular undercut or recess in the bore located adjacent to the bottom surface of the cylinder head.
