  • Patent number: 9488540
    Abstract: A barometer with multi-functions of measurement and depressurization has a body, an intake set, an exhaust set, a depressurizing set and a pressure meter. The intake set is mounted on a side of the body. The exhaust set and the depressurizing set are mounted on the body and aligning with the intake set. The pressure meter is mounted on a top surface of the body. The body has an inner channel communicating with the intake set, the exhaust set, the depressurizing set and the pressure meter. Thus, the functions of inflating, pressure measuring, depressurization and re-inflating can be accomplished by the barometer for eliminating the inconvenience of frequent installing and removing an inflation apparatus, a depressurization device and a pressure meter.

  • Patent number: 9360122
    Abstract: An expanding disk gate valve assembly comprises two gate disks and an elastomeric disk. A first flange on a first gate disk mates to a second flange on a second gate disk forming an internal volume surrounding the elastomeric disk. An elastomeric sheath covers the mated disks with the first gate disk being radially offset from, and radially movable relative to, the second gate disk. A width of the gate disk assembly is less than a width between two valve seats when the gate disk assembly is in an open position. In a closed position, the first flange moves radially toward the second flange, compressing elastomeric disk, and causes the elastomeric disk to expand axially against the two gate disks, forcing them apart, and increasing the gate disk assembly width so that the gate disk assembly actively seals against the valve seats.

  • Patent number: 9027591
    Abstract: A gas pressure regulator for use with gas delivery systems is provided. The gas pressure regulator includes, in one form, an inlet with an entry portion and a bottom portion. A pocket is disposed proximate the bottom portion of the inlet, and a cavity is disposed within a central portion of the gas pressure regulator. A guide is disposed within a lower portion of the cavity, and a flow of gas through the gas pressure regulator extends through the inlet, changes direction to flow through the cavity, and the flow of gas changes direction to impact the guide prior to flowing through the cavity. The pocket and the guide reduce the amount of particles capable of reaching internal components of the gas pressure regulator, resulting in low sensitivity and high fault tolerance to ignited particles coming through the gas pressure regulator in the event of accidental particle contamination.

  • Patent number: 8596292
    Abstract: A controlled flow drain having an upper flange coupled to a lower flange. The upper flange defines an inlet cavity and the lower flange defines a swirl chamber. The inlet cavity and swirl chamber are in fluid communication via a swirl nozzle defined within a swirl nozzle plate that separates the inlet cavity from the swirl chamber. After separating debris within the drain fluid, the drain fluid is accelerated through the swirl nozzle and discharged into the swirl chamber, and more debris is thereby separated and eventually settles into an annular groove. The drain fluid may then exit the lower flange via an exit control passage. The swirl chamber may be flushed with a series of flushing liquid injection ports symmetrically-arrayed about the annular groove. Flushing the swirl chamber removes fluidized debris and also remove any built up fouling present on the swirl nozzle and exit control passage.

The gate and sleeve, when in the throttling position, permits fluid within the fluid passage to flow out some of the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section and others of the nozzles.

  • Patent number: 6161575
    Abstract: An apparatus and a method for providing fluid communication between a process chamber and a dry pump without contamination problem are disclosed. The apparatus utilizes a conduit that has at least one gate valve installed therein for opening or closing the conduit and a T-shaped cold trap to collect large size contaminating particles. The present invention apparatus is effective in preventing particle contamination to the process chamber by a siphoning or backsteam effect when a dry pump failure occurs. While the present invention apparatus and method may be used in any deposition process which produces reaction by-products, or contaminating particles, it is particularly suitable for use in a TEOS oxide deposition process.

  • Patent number: 6098657
    Abstract: An-line trap assembly is disclosed for preventing the drop out of suspended particulant matter within a cooling water flow stream. The in-line trap assembly is provided with a collector tank for gathering debris and a bleed through piping network for creating a continuous flow of cooling water. The continuous flow of cooling water from a supply header to a return header assists in moving the debris into the collector tank where the collected sediments are then removed by a manual or automated blow-down of the in-line trap.

  • Patent number: 6049922
    Abstract: A solid-sediment retainment plumbing trap devised primarily for a sink from which substantial amounts of solid material are discharged; e.g., eyeglass manufacture and dental plastic grinders. The plumbing trap is connected to the sink, and collects sediment in a bottle having a fill line. When sediment collecting in the bottle reaches the fill line, the bottle is exchanged for a similar bottle, and the plumbing trap is once again in service. Because the bottle is connected to the rest of the trap by threads, bottle exchange is rapid and easy.

  • Patent number: 5868946
    Abstract: Water and solid debris are separated from gasoline during its storage within a container. The separation is effected automatically, at low cost and in a highly reliable manner. It is continuous throughout storage and is not reversed by portage of the container or removal of gasoline therefrom. Engines fueled with gasoline from the container are far less subject to contamination from water or impurities than those fueled from gas cans of the conventional type.

  • Patent number: 5771922
    Abstract: The present invention, in one embodiment, teaches a flow restrictor which accomplishes within a single unitary integral device cyclonic separation of larger, heavier solids from lighter smaller solids; collection of retained solids in a relatively large collection chamber; straining of certain solids to further protect the device from plugging; and flushing a fluid, e.g. the primary flow stream, through the device to facilitate removal of collected solids.In one embodiment a device according to this invention has a main body with a fluid inlet and a fluid outlet. Fluid flowing in through the inlet encounters a vaned end of a hollow mandrel with one or more vanes or a mandrel with a deflector thereon or both which induce turbulent flow in the fluid and directs solids entrained therein away from the mandrel to a solids collection area or chamber within the main body.

  • Patent number: 4975205
    Abstract: A dump truck has a tiltable dump body with a tailgate at its rear end. A partition or weir mounted in the dump body and of lesser height than the walls of the dump body divides the dump body into front and rear compartments. A siphon is connected between the two compartments and extends over the partition. The rear compartment, having a discharge opening at its rear end which is closed by a tailgate, receives dredged material in the form of a mixture of water and sand (or silt) pumped thereinto through a supply conduit on the dump body. As the rear compartment is being filled with dredged material, gravity causes the sand (silt) to settle at the bottom and the water to rise to the top and spill over the partition into the front compartment. Some water also flows through the sipon into the front compartment.
