  • Patent number: 9709081
    Abstract: A method of testing a pressurized liquid fluid for dissolved gasses includes evacuating both a first tank and a second tank. A test volume of a pressurized liquid fluid is introduced into the first tank. An initial absolute pressure in the second tank is sensed, and then fluid communication between the first tank and the second tank is opened to allow the pressurized fluid to flow from the first tank into the second tank, thereby de-pressurizing the fluid. The de-pressurized fluid in the second tank is maintained for a pre-defined out-gassing period, to allow any gasses in the de-pressurized fluid to separate from the de-pressurized fluid. A final absolute pressure in the second tank is sensed. A difference between the final absolute pressure and the initial absolute pressure is correlated to a volume of gasses released from the de-pressurized fluid.

  • Publication number: 20120125079
    Abstract: The invention is directed towards methods and apparatus for accurately detecting the presence and concentration of an oxidant in a turbid water sample. This method is very helpful in allowing accurate and efficient (not too much nor too little) amounts of microbe killing oxidants to be introduced to water supplies that require oxidants but which at present cannot be measured properly. The method comprises the steps of: passing the water through at least one filter array, passing the filtered water to an analyzer, and then returning from the analyzer a measurement of the concentration. The filter array comprises at least one filter constructed and. arranged to remove turbidity inducing material but not oxidant from the water sample. The analyzer can be a commonly commercially available analyzer that currently cannot accurately measure the oxidant concentration if the water had not been so filtered.

  • Patent number: 8171775
    Abstract: A system for measuring the permeance of a material. The permeability of the material may also be derived. The system provides a liquid or high concentration fluid bath on one side of a material test sample, and a gas flow across the opposing side of the material test sample. The mass flow rate of permeated fluid as a fraction of the combined mass flow rate of gas and permeated fluid is used to calculate the permeance of the material. The material test sample may be a sheet, a tube, or a solid shape. Operational test conditions may be varied, including concentration of the fluid, temperature of the fluid, strain profile of the material test sample, and differential pressure across the material test sample.

  • Patent number: 8156786
    Abstract: The inventive method is designed to test contaminants in soil that is contaminated with petroleum related products. The method involves the use of a container that will separate soil into a head space for analysis. The container consists of two halves and the container is partially filled with a soiled dirt specimen. The container is then hermetically sealed against the environment by way of a cover snapped over the container rim. The container with the contaminated specimen therein is allowed to accumulate a vapor head space within a certain time period. An instrument will puncture a sealed orifice in the top cover and a sample of the vapor is withdrawn for further analysis.

  • Patent number: 8132442
    Abstract: A stack of substantially parallel ceramic plates (22) separated and interconnected by ceramic spacers (26, 27) forming a seal structure (20) with a length (L), a width (W), and a thickness (T). The spacers are narrower in width than the plates, and may be laterally offset from spacers in adjacent rows to form a space (28) in a row that aligns with a spacer in another adjacent row. An adjacent plate bends into the space when the seal structure is compressed in thickness. The spacers may have gaps (60, 62) forming a stepped or labyrinthine cooling flow path (66) within the seal structure. The spacers of each row may vary in lateral separation, thus providing a range of compressibility that varies along the width of the seal structure.

  • Publication number: 20120059524
    Abstract: A method of measuring a property of entrained gas in a hydraulic liquid received by a working chamber of a fluid working motor, wherein the said property is determined from the period of time elapsing between the closure of a first valve to isolate the working chamber and the passive opening of a second valve to bring the working chamber into fluid communication with a manifold. The property may, for example, be related to the concentration of entrained gas in the received hydraulic liquid or the compressibility or bulk modulus of the received hydraulic fluid.

  • Patent number: 8071389
    Abstract: The invention relates to a method of controlling a hydrogenation of a starting material in a hydrogenation reactor, in which the amount of hydrogen reacted in the hydrogenation is firstly determined, the ratio of the amount of hydrogen reacted to the amount of starting material fed in is then derived, this ratio is compared with a prescribed value and, finally, at least one process parameter is altered if the ratio of the amount of hydrogen reacted to the amount of starting material fed in deviates by a prescribed amount from the prescribed value.
