Abstract: Compressor crankcase oil reclamation methods and systems include a coalescence filter coupled to a pressure relief vent of a compressor crankcase. The filter separates oil from an oil/gas mixture exiting the crankcase. A reservoir receives the oil so-separated. A valve restricts flow of the oil so-separated to a single flow direction running from the reservoir to the crankcase.

Abstract: A liquid storage tank has a breathing valve that vents the tank's headspace at a high-pressure value and admits an ambient gas at a low-pressure value. A controller generates a first control signal when the percentage of the catalyst gas is less than a catalyst threshold, a second control signal when the percentage of the catalyst gas exceeds the catalyst threshold, and a third control signal when the pressure in the headspace is equal to a low-pressure threshold between the breathing valve's low-pressure value and high-pressure value. The first valve is only opened to output inert gas at a discharge pressure greater than the breathing valve's high-pressure value in response to the second control signal. The second valve is only opened to output inert gas at a discharge pressure that is between the breathing valve's low-pressure value and high-pressure value in response to the third control signal.

Abstract: Compressed gas data is monitored and logged. A communication interface is coupled to a device supporting at least one of flow and storage of a compressed gas. The device senses data related to the compressed gas. The data is automatically collected via the communication interface at a first data store every first time increment of a first time period. Portions of the data from the first data store are automatically collected at a second data store every second time increment of each first time period. The second time increment is greater than the first time increment. The portions of the data are collected for a second time period which is greater than the first time period.

Abstract: A method is provided for monitoring and logging data related to a compressed gas operation. A communication interface is coupled to a device supporting a compressed gas operation. Data related to the compressed gas operation is automatically collected via the communication interface at a first data store every first time increment of a first time period. Portions of the data from the first data store are automatically collected at a second data store every second time increment of each first time period. The second time increment is greater than the first time increment, and the portions of the data are collected for a second time period which is greater than the first time period.

Abstract: A tank data storing and monitoring system and method have an RFID tag coupled to and associated with a tank. The RFID tag has a unique identity specified by a unique identifier stored electronically on the RFID tag. Also included are an internet-accessing computer and database. The database stores data unique to the tank having the RFID tag coupled thereto. An RFID reader coupled to the computer is used to read only the unique identifier of the RFID tag. The computer accesses the data unique to the tank stored on the database using the unique identifier.

Abstract: Operational facets of a compressor are controlled from a remotely-located computer. Data from the compressor is automatically collected at a first data store every first time increment of a first time period. Portions of the data from the first data store are automatically collected at a second data store every second time increment of each first time period. The second time increment is greater than the first time increment, and the portions of the data are collected for a second time period which is greater than the first time period. Successful verification of user authentication data collected at the computer causes automatic generation of an image of application icons at the computer to enable the computer as an input device for controlling the compressor and selections of routines available at an analytics visualization generator that uses data from the second data store.

Abstract: A radio frequency identification (RFID) tag positioning system includes a tag holder having a first region with a slot extending from an edge of the first region, and a second region extending from the first region. When an RFID tag having an antenna is disposed in the slot of the tag holder and when the tag holder is adapted to be retained adjacent a filling fixture of a gas tank with the second region adapted to be in contact with the gas tank so that the slot is approximately perpendicular to a longitudinal axis of the gas tank, the RFID tag's antenna is approximately perpendicular to the longitudinal axis of the gas tank.

Abstract: A tank support system includes a hollow open-top container having a contiguous sidewall region and a bottom region coupled to the sidewall region. A loop antenna is coupled to a portion of the container's sidewall region. A tuning circuit coupled to the loop antenna provides for adjustment of the loop antenna's electrical impedance. A radio frequency identification (RFID) reader is coupled to the tuning circuit.

Abstract: This invention concerns a gas assist mold dump valve positioned between a gas controller and a mold cavity. Preferably, the valve includes a pressure regulator having a body with a gas inlet and a gas outlet. A vent is formed in the body between the gas inlet and the gas outlet. The inlet is in fluid communication with the gas controller and the outlet is in fluid communication with the mold cavity. A piston is mounted for reciprocal motion within the body and is movable between a first position to close and a second position to open the vent. Finally, a check valve communicates with the inlet and the outlet and has an open position that allows gas to flow from the inlet to the outlet and a closed position to close off the flow of gas from the outlet to the inlet. In operation, gas entering the inlet urges the piston toward its first position, passes through the check valve into the outlet and then enters said mold cavity.

Abstract: A paintball cylinder refilling apparatus for installation and use at a paintball field or tournament includes a housing, a high-pressure and a low-pressure fluid source. The housing has a paintball cylinder refill circuit that includes a high-pressure circuit adapted to refill a paintball cylinder and a low-pressure circuit that operates to open and close the high-pressure circuit. The high and low-pressure circuits are also adapted to safely vent into the atmosphere any pressurized fluid that may be resident in either circuit following the termination of a cylinder refilling operation.
