Abstract: A delivering tap for delivering liquids from a container includes a main body with a connecting element having fitting means with the container, and a supporting body adapted to be closed by a plug associated with a cam seal, the supporting body comprising a first opening for exiting liquid, and sealing means associated with the first opening and plug, the supporting body comprising external guiding means obtained on its external surface to guide the plug in the opening and closing of the plug cooperating with a cam profile, the plug comprising a central cylinder having lower sealing means obtained at its lower end and adapted to be coupled with the sealing means of the main body to determine the seal of the plug next to the first opening, the cam profile being made of two parts, the first part on the plug and the second part on the cam seal.

Abstract: The invention is directed toward a T-pipe designed for transfer of high pressure fluids through the main run and where the branch run is left in a standby position for possible use in the future. The opening, or outlet, of the branch run is sealed by a material continuous with the main run. An opening and fluid flow in the branch run while the main run is in production and remains under full pressure, is to be provided. The sealing includes a metal membrane which is in contact with the fluid flowing in the main run. The metal membrane is thinner than the wall thickness of the T-pipe and is supported by a plug inserted in the branch run.

Abstract: A method and device is provided for tapping an existing primary pipeline (e.g., a water supply line) without cutting the existing primary pipeline. A secondary supply line may be installed by coupling the device to a valve of the existing pipeline. In various implementations, the device may have a single port serving as both an input (i.e., an inlet) and an output (i.e., an outlet). Among other advantages, the invention may be used to avoid costly procedures of cutting supply lines, to prevent water spillage, to integrate with existing alarm and home improvement systems, and to communicate wirelessly with utility companies for billing purposes.

Abstract: A valve assembly includes a valve body with an access opening in which a linearly installed but pivotally operated gate-like valve-stopping mechanism is disposed, said mechanism including a support structure or cartridge with a pivotally moveable valve-stopping element or isolator (e.g., a butterfly element). A method for hot tapping a pipeline with a valve assembly as described above proceeds by (i) connecting the valve body to a line to be tapped, (iii) connecting a hot-tapping machine to the valve body, (iv) connecting a bonnet holding the valve-stopping mechanism to the valve body over the access opening, (v) hot tapping the line, (vi) advancing the valve-stopping mechanism into the valve body interior, and (vii) disconnecting the hot-tapping machine from the valve body with the valve-stopping element pivoted to the first position where it stops fluid communications. The gate-like valve-stopping mechanism can replace a gate in an insert valve (IV) or a repair-under-pressure (RUP) valve.

Abstract: An irrigation system for selectively providing water to various plants in a relative same area with different rates of application of water. The system has a first valve for connecting a water supply with a tube in a edging. The edging has vertical web with a flange for locating the tube in a fixed position within the area with respect to various plants. A plurality of second control valves are located on the tube in a plane tangent to the web such that a first end cap on each of the control valves is below an apex of the tube. Each second valve is characterized by a body having a first projection that extends into the tube. The body has a stepped axial bore that extends into the first projection to meet a cross bore for communicating water presented to the tube into the stepped axial bore. The stepped axial bore is connected to an outlet port in a first end cap by an internal port.

Abstract: A drink dispenser includes a body of a head of the device having a cavity that defines a three-way passageway, the cavity containing a tubular element which is slidably movable along an axial direction of the tubular element between a first and second end run position. The tubular element includes a lateral wall that is placed against the first passageway so that the drink can flow from the second passageway into a third passageway. The tubular element is mechanically interconnected by rack-and-pinion links contained in the body to a drink intercept valve having an obturator and a valve seat, with the obturator being rotatable relative to the valve seat so that the drink can flow between the third passageway and into a drink delivery line.

Abstract: A retrieving device for the assembly and disassembly of probes into process pipes and tanks comprising a hydraulically activated cylinder attached to a nipple and ball valve mounted on the wall of a pipe or tank and the cylinder may be operated by applying a suitable pump. A pair of pistons are inserted within the cylinder and these pistons are arranged in telescoping fashion. A piston rod attached to one of the pistons is constructed so that it can securely attach to a probe or other device. a fluid pressurizing means which includes a pair of hydraulic tubes are attached to the upper and lower ends of the hydraulic cylinder so that hydraulic pressure can be applied to extend the pistons and insert the probe or retract the pistons and remove the probe. The ball valve is closed and the retrieving device can then be removed from the valve to service and replace the probe. When the probe is inserted within the nipple a sealing device seals the probe against fluid leakage from the pipe or tank.

Abstract: Electrical apparatus includes an outer enclosure, an electrode within the enclosure, and an insulating gas electrically insulating the electrode from the enclosure. A support plate is secured to the outer enclosure, and the support plate has an opening therein. A housing, containing valve means, is secured to the support plate adjacent the support plate opening. An end plate is secured to the end of the housing. The valve means in the housing are capable of being in two positions, a first position preventing the flow of gas past said valve means, and a second position wherein an opening which is through the valve means is aligned with the support plate opening.An opening is formed through the enclosure in the wall portion thereof which is in alignment with the support plate opening. The opening through the enclosure is formed without generating contamination particles within the enclosure and in a manner which minimizes escape of gas from the enclosure.

Abstract: There is provided a catheter having a hub portion in which a rotatable intravenous receiving member is mounted. In one position the rotatable member provides a passageway for a needle passable through the rotating portion and the hub end and extending portion of the catheter. After insertion of the catheter into the patient, the needle is withdrawn from the assembly. Before inserting the needle into the patient and then withdrawing the needle from the assembly, an end of an intravenous conductor is connected to the receiving socket in the rotating portion and placed in a fluid-flow condition or the intravenous connector can be inserted after venipuncture. After the needle is withdrawn, the rotatable portion is turned to bring the connected fluid source into flow condition to and with the catheter. A filter may be provided in the passageway of the fluid conduit in the rotatable portion.

Abstract: A method and apparatus for a tapered pipeline seal includes a means for enabling a line to be sealed with a rotatable tapered sealing plug or apparatus.

Abstract: A cap assembly is provided for use with a container for storing and supplying aqueous ammonia to a diazo type copying machine. The cap assembly comprises a closure member mounted on the container and a key device associated with free ends of an ammonia feed tube and a drain tube connecting the container to a developer system of the copying machine. The closure member includes a feed outlet to permit ammonia flow from the container to the feed tube and a drain outlet to permit ammonia flow from the drain tube to the container. The closure member also includes a seal adapted for selective actuation by the key device between a first position for closing the feed and the drain outlets to prevent ammonia flow and a second position for opening the outlets to permit ammonia flow.
