    Abstract: An improved double block and double bleed stream switching system (modifiable to, for example, a double block, single bleed stream switching system) includes a common stream path for a multitude of gas streams from, for example, a process pipeline. The improved stream switching system includes a heating mechanism and insulation oven to help temperature stabilization, along with a structure to separate temperature sensitive solenoids from the heated area. Pre-heat coils are located between the sample switching system and the sample shut off system to warm the gas sample and to act as a flow restrictor. A first embodiment is suited for the Division 1 environment and a second embodiment is suited for Division 2 uses. The improved stream switching system may also feature membrane or cartridge filters located upstream of the sample wetted portion of the stream switching system.

  • Patent number: 7000633
    Abstract: A filter is annularly attached around a peripheral wall of a housing. The filter is composed of a filtering element that covers a fluid passage for inhibiting foreign objects from entering, a supporting portion for supporting the filtering element, and a connecting portion for connecting between both ends of the supporting portion. The connecting portion is narrower than the supporting portion. The filter is movable radially in two directions according to a clearance between the filter and the housing. A contact portion is formed, with being able to be slid within a movable range of the filter, between an outer surface portion of the peripheral wall that surrounds an opening of the fluid passage and an inner surface portion of the filter that surrounds the filtering element.

  • Patent number: 6915818
    Abstract: A fluid pick up device for removing fluid from storage tanks includes an intake, a submerging member that maintains the intake submerged in the fluid, and a float that enables the intake to move in relationship to the level of fluid. The submerging member can include an extension communicating with the intake. The extension can be an adjustable arm connected to a delivery member by a swivel joint. A stopping member can control the arm's range of motion. The intake is angled downward, and the length of the arm is set to prevent the intake from passing into a contaminated volume of fluid near the tank bottom. The intake can also be movable. The adjustable arm can retract into the delivery member.

  • Patent number: 6913040
    Abstract: A hydraulic fluid reservoir apparatus for an automotive power steering system comprises a filter chamber, and a filter parallel to a vertical axis and dividing the filter chamber into an upstream region and a downstream region. The reservoir apparatus also includes a stagnant fluid well apart from the filter chamber, and a de-aeration zone overlying the filter chamber. A vent is provided between the upstream region and the de-aeration zone. Fluid recycled to the reservoir apparatus contains entrained gas. The filter separates the gas from the fluid within the upstream region, whereupon the gas is vented to the de-aeration zone and separates from the fluid circulated to the stagnant fluid well.

  • Patent number: 6899125
    Abstract: The flow-adjusting device comprises: a housing (2) having an inlet channel (4) and an outlet channel (5) to be connected with respective pipes (6) through which a liquid is caused to flow, a closure assembly (7) arranged in the housing (2) between the inlet and outlet channels (4, 5) for drivingly adjusting the flow of the liquid, and a deformable diaphragm (3), deformation of which takes place in proportion to the liquid pressure in the outlet channel (5) and which is active on the closure assembly (7). The device also comprises a hollow body (15) internally bounding a storage chamber (16) disposed between the inlet and the outlet channels (4, 5), the storage chamber (16) having a lower portion (16a) to be engaged by the liquid and an upper portion (16b) defining an air-tight region wherein air under pressure is stored under the effect of increasing pressure of the liquid and causes recirculation of the liquid on decreasing of the liquid pressure.

  • Patent number: 6799702
    Abstract: A liquid dispensing device including a body generally having an air passage and a liquid passage. A valve seat is connected to the body and a valve stem is mounted for movement within the body with respect to the valve seat. A piston is caused to move by pressurized air, and is caused by a spring and optionally, air pressure above the piston, to return to its normal position when the air pressure is relieved. The stem is connected to the piston so that it is caused to move linearly to and from the valve seat. The stem is not rigidly connected to the piston, allowing the piston to find its center in the air cylinder and the stem to find its center in the liquid chamber. The piston is mounted with two bearing points so that it is not affected by uneven spring pressure. The stem is located by two bearing points, the adhesive seal and the seat. The air cylinder body and valve body are separated by a large open area.

  • Patent number: 6797156
    Abstract: A water treatment unit is disclosed which can be mounted directly on the faucet or tap of the user's sink and which contains one or more water treatment media and an operating valve which permits the selection of several operating modes including service, spray and stream modes. In the service mode the water is treated by at least one if not all of the various water treatment media contained in the unit housing after which the water is discharged from the valve of the unit for service use, and the service discharge may be adjusted to direct the treated water as desired by the user. The valve of the treatment unit includes a housing, a stationary member, a slide member and a rotatable switch member unit and may also be operated in a backflush mode in which water may be directed in the reverse direction through at least one of the water treatment media to regenerate that media.
