Gas Or Variation Of Gaseous Condition In Receiver Patents (Class 141/4)
  • Patent number: 6032438
    Abstract: A controlled environment gassing system is provided for removing the existing environment from containers. The existing environment may be purged by passing the containers along a gas distribution manifold disposed parallel to the direction of travel of the containers. The manifold includes at least one region of flow resistance disposed parallel to the direction of travel, and the manifold may have a width less than the width of the container and/or screen openings sized to provide a laminarized flow, for supplying a controlled environment gas flushing stream continuously and at substantially steady state to the containers. As the containers pass along the manifold, the controlled environment flushing gas creates an optimal flow pattern which consistently and steadily removes the existing environment from the containers while preventing the flushing gas from drawing in air. Return gas chambers are provided to retrieve the gasses exiting the container as they are purged.

  • Patent number: 5970786
    Abstract: A compressed natural gas (CNG) vehicle refueling system is designed for refueling fleets of vehicles with identical fuel tanks. The amount of CNG dispensed into the tanks may be closely approximated without the use of a flow meter. An initial standardized volume is calculated based upon the ambient temperature, the initial pressure level and an approximate compressibility of the gas. Gas is dispensed into the fuel tank to a desired pressure which is confirmed with a pressure gage. A final standardized volume of gas contained within the fuel tank is calculated based upon the final pressure level and assuming no change in the compressibility of the gas. The initial standardized volume of gas is subtracted from the final standardized volume of gas to yield an actual volume of gas dispensed from the storage vessel. Empirically derived temperature correction factors may be used to generate an even more accurate approximation of CNG dispensed.

  • Patent number: 5704405
    Abstract: For metering of heavy gas which is intended for use in filling insulating glass panes with heavy gas or in the assembly of heavy gas-filled insulating glass panes, heavy gas is introduced into A space (5) of a cylinder (1) whose internal space is divided by a piston (2) into two spaces (5 and 6), piston (2) moving as other space (6) becomes smaller, so that heavy gas flows out of the latter. The displacement path of piston (2) is measured by displacement sensor (7) and electronic rule (4). Furthermore, the temperature and pressure of the heavy gas flowing out of space (6) via connection (20) are measured and the displacement of piston (2) is interrupted as soon as the amount of heavy gas determined on the basis of the displacement path and the values of temperature and pressure of the discharging heavy gas corresponds to the required amount of heavy gas.

  • Patent number: 5676782
    Abstract: To produce insulating glass panes (10) filled with heavy gas, an insulating glass pane (10) still open at least in the area of its lower edge is filled from underneath with heavy gas. To do this the two vertically oriented edges of the insulating glass pane (10) are sealed by seals (30, 31). The upper edge of the insulating glass pane is not sealed. At at least one site (156, 157) in the area of the lower edge, the heavy gas from a channel (122) which runs along a belt conveyor (9) which supports the insulating glass pane (10) is blown via openings which pass between side-by-side portions of the conveyor belt of the belt conveyor (9), into the insulating glass pane (10). To adjust the effective length of the channel (122) to the length of the insulating glass pane (10) to be filled with heavy gas, a piston (130) is contained in the channel. As soon as the space between the glass sheets (11, 13) of an insulating glass pane (10) is entirely filled with heavy gas, the insulating glass pane (10) is closed.

  • Patent number: 5655578
    Abstract: The invention described in the patent is an automatic control system which provides monitoring, supervision, and control of the process of filling of a tank or container with a liquid, where at the temperature of operation the vapor pressure of the liquid is at or above atmospheric pressure. The invention provides an improved method of carrying out the process of filling of tanks with liquids such as ammonia, chlorine, propane, liquefied petroleum gas or any other liquid with high vapor pressure at the temperature of operation. The main advantage provided by the apparatus and method of the present invention is that an improved means is included for automatically stopping the filling process at the correct point, so as to avoid a possibly hazardous overfilled condition. One of the methods currently in use requires a mechanical valve which senses liquid level in the tank and is supposed to close so as to stop flow to the tank when the liquid has reached the maximum allowable level.
