A plume of combined gases are infused into hydrocarbon-bearing formations, “inert” as the major gas and “reactive” as the minor gas, where the minor gas reacts with hydrocarbons to fully saturate hydrocarbons with supercritical fluid, which migrate hydrocarbons out of formations, even at great distances from the regulated fuel cell source. Coal, tar sands, petroleum-contaminated soil, and / or oil wells that have lost gas pressure can also be desorbed by this in-situ method.

Managing pressure within a thickness-control-zone (muffle door) housing (20) relative to pressures in a glass-making machine enclosure (60) and an upper chamber (40)—that is disposed outside the enclosure—so as to minimize or control undesired airflows that would adversely affect thickness (9) of glass ribbon (8). According to one pressure-management technique, the pressure at a location (25) in the housing (20) is managed so as to be less than the pressure at a location (65) that is within the enclosure (60) as well as both outside and adjacent to the housing. In the event of a leak, as by a crack or unintended opening in the housing, for example, this pressure difference reduces or prevents airflow toward the ribbon and, thereby, undesired thickness variation in the ribbon. According to a second pressure-management technique, the pressure at location (25) is managed so as to be greater than the pressure in the upper chamber.

A stopper includes a hollow casing with a resilient, ribbed sleeve that forms a valve seat. An interior plunger has a tip configured to mesh with the valve seat when in its down position and to open the valve when in its up position. An upper flange in the plunger provides an additional seal and is visible through a transparent wall in the casing. A vacuum in the bottle draws the plunger downward increasing the pressure with which the plunger presses against the seat, thus securing a long-lasting seal that maintains the vacuum in the bottle. When the vacuum is released, the resilience of the seat structure pushes the plunger upward, rendering it visible as an indicator of vacuum through the transparent wall. An opening in the casing allows connection to a pump to create the vacuum in the bottle.

The invention concerns a process for the treatment of heat-sensitive fluid food products (P) in a UHT system (1), particularly dairy products such as milk, cream, milk protein concentrate, according to the preamble of Claim 1. The invention has the task, in a UHT system whose basic structure using an infusion chamber is described in [4], of ensuring an equal and constant dwell time as well as an equal and constant temperature trend for the entire treated food product downstream of an outlet of a mechanism in which the food product is subjected to direct heating by the introduction of steam, and to minimize fouling during heat maintenance of the food product in this area. This is achieved using process technology in that:The heated food product (P*) upstream of its heat main undergoes a predetermined pressure increase (Δp) at a predetermined, unchanging location, andThe pressure level upstream of the location before the relief lies above the pressure upstream of the location before the pressure increase (Δp) (FIG. 1).

A method, for detecting overpressure inside a compartment associated with a gas turbine nacelle, includes: a) measuring one or more predetermined operating conditions nominally affecting the temperature inside the compartment; b) determining a reference temperature for the compartment, corresponding to a nominal reference zone pressure, on the basis of the measured operating condition or conditions; c) measuring the actual temperature inside the compartment, corresponding to the actual compartment pressure; and d) using the measured actual temperature in the compartment and the determined reference temperature for the compartment to assess the gas pressure inside the compartment. A system for assessing the gas pressure inside the compartment caused by an associated pressure system failure includes using a quantified mass leakage flow to assess gas pressure inside the compartment. The quantified mass leakage flow may also be used to detect excessive mass leakage flow by comparing the quantified mass leakage flow with a predetermined mass flow leakage.

In an engine controller capable of carrying out spark ignition type combustion and compressed self-ignition type combustion, in order to suppress operation performance deterioration and exhaust performance deterioration at the time of switching a combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion, intake pipe pressure downstream a throttle is quickly reduced by making the throttle opening degree smaller than a target throttle opening degree of the spark ignition type combustion immediately after switching for a certain period during the combustion mode is switched from the compressed self-ignition type combustion to the spark ignition type combustion. As a result, responsiveness of an intake amount at the time of switching the combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion is enhanced, and combustion switching without exhaust deterioration and torque variation is realized.

Disclosed is a method for measuring leakage flow rate of a valve wherein fluid flows through the valve in a single-phase flow of a gas or steam. The underlying principle upon which the leakage flow rate may be determined is that the heat loss across a length of bare pipe located downstream of the valve causes a decrease in the temperature of the leakage flow. Also disclosed is a method for measuring the leakage flow rate when the fluid passing through the valve transitions from a liquid-phase flow into a two-phase flow of liquid and steam. In two-phase flow, the underlying principle upon which the leakage flow rate may be determined is that any leakage of the valve will cause an increase in the pressure on the downstream side of the valve because of frictional resistance to flow in the downstream piping which corresponds to an increase in temperature thereof.
