Abstract: Three-dimensional structures providing a plurality of separate interpenetrating, three-dimensional domains or channels or flowpaths, each of said domains or channels or flowpaths being a closed system of connected porosity or permeability and each of said domains or channels or flowpaths being interpenetrating within said structure, have been prepared. These structures are prepared from porous permeable precursor materials having a single three-dimensional domain or channel or flowpath as described above. Suitable precursor materials are provided by the abundant porous carbonate skeletal material of marine life, e.g. the coral Porites skeletal aragonite. For example, by coating the surfaces of such materials with a liquid material capable of being cured or set to a solid, followed by curing or setting and dissolution, e.g.

Abstract: The invention provides, at the end of a pipe which extends a valve being part of an exhausting device for pressure-relieving a pressurized fluid, a nozzle which is exactly at the input of a hood, the convergent portion of said nozzle reducing its exit section so as to make it substantially double the maximum passageway section through the valve.

Abstract: Natural gas from one or more wells is gathered, dehydrated, compressed to a relatively high pressure, and loaded into pressure vessel means mounted for transporting at ambient temperatures by a transport vehicle. The pressure vessel means is then driven to a transmission pipeline terminal, or other end user, and the natural gas is off-loaded while being heated to prevent the formation of harmful hydrates, the gas being metered before flowing into the pipeline.

Abstract: A recycle system for polymerization of monomers to produce polymers of wide-molecular weight distribution comprising two reactors and two conduit lines disposed between said two reactors for forming a cyclic path, and means disposed in said lines for conveying the contents of one of said reactors to the other without affecting the polymerization conditions in each of said reactors which conditions may be different.

Abstract: In an aircraft flight line servicing system there is provided an electrical power unit and an air compressor from which extend respectively a plurality of electrical and air distribution lines and a plurality of service islands are each connected to all of the electrical and air distribution lines. Each service island is provided with components for supplying both starting air and cooling air and electricity to aircraft. The distribution lines and service islands may be detachably mounted upon the surface of the flight line and have such a height and shape so as to enable aircraft tires to pass thereover.

Abstract: An assembly of pipes and flow control means (e.g., valves) carried by a supporting frame (e.g., a skid) and forming a modular unit for field assembly of flow distributing or diverting systems of the type used in the petroleum industry in connection with tank farms. The piping of each assembly unit has ends for coupling with associated piping and like associated assembly units, with the ends disposed in vertical planes that are coincident with the corresponding sides of the frame, thereby facilitating field assembly of the units to form a desired overall system.

Abstract: Solenoid-actuated valve adapted for heavy duty use by having the coil of the solenoid divided into high and low power windings connected in and automatically energized in succession by a solid state control circuit for providing in sequence high power of predetermined short duration for opening the valve and low power of usually longer duration for holding the valve in open position.

Abstract: A shut-off and regulator device for controllable mechanisms intended for installation in pipelines, comprising a shut-off and regulating element movable between a closed position for engagement with a sealing seat and for inhibiting the flow of a pressurized fluid medium, and an open position, under the control of the pressurized medium, the shut-off and regulating element comprising a tubular spool sleeve which is adapted to be sealed in relation to a guide parallel to the pipeline when the device is installed and to move in relation thereto, and the sealing seat comprising an annular sealing face on a seat element fixed inside the spool sleeve, the seat element containing at least one passage, which in the open position, forms a through passage in association with at least one passage contained in the spool sleeve.

Abstract: This invention relates to a molded fluid circuit plate which is used in a circuit module that distributes fluid under pressure to a plurality of logic control valve devices that may be removably secured to the circuit module. This molded fluid circuit plate constitutes a slab that has formed in either one or both of its sides, or has extending therethrough, a plurality of polygonal chambers, each chamber being separated from the adjacent chambers disposed thereabout by a plurality of partitions. When the chambers are formed in one or both sides of the circuit plate, one edge of each partition is integral with and severable from the corresponding side of the circuit plate.

Abstract: A device for monitoring and adjusting the temperature of multiple cooling circuits in which a monitoring unit with a float-type flow gauge, a temperature gauge and a throttle valve is associated with each cooling circuit, and several units are assembled in a monitoring bank. A main liquid supply pipe and main liquid outlet pipe support the bank adjustably on the machine for supervision by an operator.

Abstract: A modular distributor box for distributing a fluid, consisting of a linear assembly of juxtaposed prismatic modules with contiguous modules connected together by engagement of a projection having an undercut, preferably dovetail, cross-section of one module engaging with one of at least two similarly undercut intersecting grooves of a corresponding face of the next module, each module having a central conduit therethrough between the faces on which the grooves and projections are defined so that the assembled distributor box has a continuous longitudinal conduit extending therethrough. The ends of the box may be blanked off with releaseable plugs. Transverse conduits formed in the various modules of the distributor box may include pressure sensors, manometers branching pipes or blanking plugs, and at least one of the modules may include a shut off tap effective to close said central conduit.

Abstract: A steam supply apparatus includes at least two pipes located in spaced apart, side by side relationship, and a cover member extending across the pipes and secured thereto. End members are secured to the respective opposite ends of the pipes, and a pair of baffles between each pair of pipes are secured thereto in a substantially V-shaped configuration with a slot between adjacent ends of the baffles at the base of the V-shape, the base of the V-shape being directed towards the cover member. Steam is supplied to the pipes, and each pipe has a series of apertures communicating the interior of the pipe with the space between the pipes, the cover member and the baffles.
