    摘要： A gas separation and detection tool for performing in situ analysis of borehole fluid is described. A separation system such as a membrane is employed to separate one or more target gasses from the borehole fluid. The separated gas may be detected by reaction with another material or spectroscopy. When spectroscopy is employed, a test chamber defined by a housing is used to hold the gas undergoing test. Various techniques may be employed to protect the gas separation system from damage due to pressure differential. For example, a separation membrane may be integrated with layers that provide strength and rigidity. The integrated membrane separation may include one or more of a water impermeable layer, gas selective layer, inorganic base layer and metal support layer. The gas selective layer itself can also function as a water impermeable layer. The metal support layer enhances resistance to differential pressure. Alternatively, the chamber may be filled with a liquid or solid material.

    摘要： A dual-mode thickness-shear quartz pressure transducer includes a unitary piezoelectric crystal resonator and cylindrical housing structure wherein the resonator is located on a median radial plane of the housing and the exterior of the housing is provided with a pair of parallel flat surfaces which are located at an angle relative to the X" axis of the resonator. According to the presently preferred embodiment, the transducer is made from an SC-cut or a WAD-cut solid quartz crystal cylinder which is ultrasonically milled to form a plano-convex or bi-convex resonator disk in the medial radial plane of a hollow cylinder and the pair of exterior flats. The wall thickness of the cylinder is altered at the location of the flats such that stresses at the center of the resonator disk are anisotropic. According to the invention, the ratio of the stresses at the center of the resonator disk along the X" and Z" axes are optimized such that the pressure sensitivity of the third thickness harmonic of C mode vibration is maximized. Optimization of the ratio of the stresses along the X" and Z" axes is accomplished in particular by altering the (azimuthal) angle of the flats. According to a presently preferred embodiment of the invention, the flats are located at an azimuthal angle of approximately 134.degree. relative to the X" axis of a WAD-cut resonator.

    摘要： An electrochemical sensor for measuring contents of a fluid or gas at high pressure and/or high temperature, for use, for example, in a wellbore for hydrocarbon applications, is provided. The sensor includes: a bulkhead-like electrode assembly including a cylindrical housing and a cylindrical electrode structure. The cylindrical electrode structure includes a cylindrical conductive pin extending from a high pressure region to a low pressure region and an electrode connected to one end of the pin at the high pressure region and having an electrode surface for exposure to a flow path of the fluid or gas in the high pressure region. At least a part of the surface of the pin is protected from direct contact with the fluid or the gas by an insulating coating impermeable to the fluid or gas. The pin may include an alternating pattern of protruding and receded portions.

    摘要： A pressure- and temperature-sensitive transducer comprises a tubular housing, a resonator located within the housing and end caps closing the ends of the housing. The resonator is located in a radial plane with respect to the housing and is connected to the housing by two separate connecting regions. The housing, resonator and connecting, regions are formed from a single piece of double rotation cut quartz. The shape, dimensions and position of the connecting regions is chosen to optimize stress in an axis responsive to changes in pressure and temperature while minimizing stress in an axis responsive predominantly to pressure.

    摘要： The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way. This is to prevent the user from accidentally disconnecting the reservoir when what is really wanted is a dispensation of soap. Should the reservoir be disconnected, pushing in and releasing the plunger will not result in the first outlet valve to open, because pressure will not be lowered in the metering chamber when the plunger is released.
