Abstract: The invention relates to a discharge system for combustion gases of a gas turbine or the like, whereby one end of a discharge pipe is connected to the gas turbine or the like. The other end of the discharge pipe is connected to a heat exchanger. A branch pipe, which extends transversely to the discharge pipe, is connected to the discharge pipe. A valve mechanism is adjustable between a first position, in which the end of the branch pipe connecting to the discharge pipe is closed, and a second position, in which the discharge pipe is closed downstream of the connection of the branch pipe to the discharge pipe. The passage of the branch pipe is larger than that of the discharge pipe.

Abstract: A suction control valve is disclosed that vents to atmosphere the residual vacuum pressure presented to a suction catheter or similar device when the central bore of the valve is completely blocked by a valve member and the device that the suction control valve is controlling becomes occluded. A vent bore extends from the central bore through the valve body underneath the valve member. A vent channel is formed in the underside of the valve member longitudinally aligned with the vent bore and extending a small distance along the underside of the valve body from the end of the valve body. The length of the vent channel is such that when the valve member completely blocks the central bore, the vent channel is positioned over the vent bore thereby forming a vent path from the central bore through the vent bore and vent channel to the atmosphere. Unless the valve body is in the fully closed position, the vent bore is not aligned with the vent channel.

Abstract: A system for heat exchange processing of particulate solid material is disclosed. The particulate solids are flowed by gravity through a housing packed with flat, internally cooled (or heated) heat exchange panels spaced apart to define generally vertical channels for the passage of the solid particulate. The panels are formed of opposed metal sheets, sealed around their edges, spot welded together in limited areas of joinder, in a predetermined pattern over their surfaces, and hydrostatically expanded in the areas between to form surfaces that are quilt-like in appearance. The panels are configured in two alternate forms such that, when a plurality of panels are assembled in a stack, the hydrostatically expanded portions of one panel are disposed opposite the areas of joinder of an adjacent panel of alternate configuration, creating a sinuous, but relatively uniform flow path for the flow of particulate solids between panels.

Abstract: A fluid valve has a valve housing defining a corner and having a valve housing cover opposite that corner. That valve housing and cover enclose a valve chamber therein. A fluid inlet or outlet is in the valve housing cover. First and second valve seats for further fluid inlets or outlets are in first and second sides, respectively, of the corner in the valve chamber. A flapper is in that chamber for selectively closing the first valve seat and alternatively the second valve seat. A flapper actuator is in the corner of the valve housing. There may be an expansible valve closing member for each valve seat. Such expansible valve closing member may have an aperture paralleling that valve seat. A pilot valve may be at the expansible valve closing member for closing its aperture. Opening of the valve is initiated by moving the pilot valve away from the aperture in the expansible valve closing member, and such opening of the valve is completed by pulling the expansible valve closing member away from its valve seat.

Abstract: A ram of a ram-type blowout preventer is enclosed within an enclosure so that the piston driving the ram is placed parallel to a stationary magnetizable waveguide tube. A transverse ring-like magnet assembly surrounds the tube and is attached to a carrier that, in turn, is attached to the tail of the piston. The magnet assembly longitudinally magnetizes an area of the tube where it is located. A wire running through the tube is periodically interrogated with an electrical current pulse, which produces a toroidal magnetic field about the wire. When the toroidal field intersects with the longitudinally magnetized area, a magnetostrictive acoustical return pulse is reflected back up the tube for detection by a transducer located outside of the enclosure. The time that the acoustical pulse travels from the magnetic field intersection compared to the timing of the electrical pulse on the wire is a measure of distance since the pulse time essentially travels at the speed of light.

Abstract: A solenoid valve comprising an inlet conduit coaxial with an exhaust conduit; and an on-off element supported on the anchor of an electromagnet and moving substantially along the common axis of the two conduits for alternately connecting the inlet conduit and the exhaust conduit to an outlet conduit via a connecting compartment. The anchor normally closes the inlet conduit via flexible means, such as a permanent magnet in the magnetic circuit of the electromagnet, magnetized the opposite way to when the electromagnet is energized. The action of the electromagnet is such as to substantially eliminate that of the magnet on the anchor, which is thus set rapidly to the closed position over the exhaust conduit.

Abstract: In a sealing element for use in particular in high vacuum technology, a moveable closure unit (4) is closed tightly against a fixed outer flange (1) whose sealing surface (2) is preferably conical. The closure unit (4) comprises a hat-shaped outer part (5) with a flat base (8) and a sealing surface (7) around the periphery; and an inner part (6) concentric with, and smaller in diameter than the outer part. Between them are one or more spring elements (10), arranged as segments on a ring, which act as a disk spring; these are supported by the outer and inner edges on the outer (5) and inner (6) parts. The spring elements (10) are mounted at an oblique angle radially towards the base (8) of the outer part (5) in such a way that when the base (8) of the outer part is subjected to pressure, the radial force is produced at the sealing surface (7) of the elastically deformable outer part (5) and its base (8) is pressed inwards.

Abstract: A valve assembly having a plurality of solenoid operated valving operators, each attached by non-metallic weldment to a manifold having a plurality of outlets. Two of the operators are adapted for connection to separate fluid sources such as hot and cold water and individually valved flow to a common mixing outlet on the manifold and also supply unvalved flow to an auxiliary passage in the manifold. Others of the valving operators are connected to receive flow from the auxiliary passage and provide valved flow individually to others of the outlets.

The system includes two independent flow passages formed between each process gas supply pipeline and a purge gas supply pipeline. The system further includes plurality of flow passages each of which is connected between one of the process gas supply pipelines and the process apparatus. Each of the process gas supply pipelines can be purged independently and the stagnation of gas in the pipelines which are not in use can be prevented by flowing purge gas constantly therethrough.

Abstract: A supply valve includes a first valve member formed with a plurality of ports which communicate with containers of different fluids, and a second valve member having a single port which communicates with an inlet of a chamber into which the fluids are selectively supplied. The second valve member sealingly and slidingly engages with the first valve member, and is movable by a computer-controlled motor drive relative thereto in two directions to positions in which the port of the second valve member communicates with the ports of the first valve member respectively. Each position has unique coordinates in the two directions such that the fluids can be selected in any sequence. In one embodiment, the first valve member is a cylinder having a bore with an axis and the second valve member is a piston which is coaxially received in the bore, and the two directions are rotation above the axis and translation along the axis respectively.

Abstract: A fluid closing action dampened shutoff valve for closing a high pressure fluid conductor is formed by a valve body interposed in a high pressure fluid conductor. The valve body contains a valve seat and a normally open valve for seating on the seat and interrupting fluid flow through the valve body in response to fluid pressure above a predetermined value in the conductor. The valve includes a stem slidably supported by and projecting, at one end portion, outwardly of the body. An end plate is secured to the body by posts in axially spaced relation with respect to the valve stem and axially supports a dashpot on the valve stem and a pressure collapsible rod-like pin axially interposed between the dashpot and the end plate.

Abstract: A gas inlet (4), a stop value (7), a pressure reducing valve (8) and a gas outlet (5) are arranged in series within a valve casing (3). The gas outlet (5) and an outlet (7b) of said stop valve (7) are communicated with each other by a gas charging passage (10) provided with a check valve (11). The gas outlet (5) is communicated with a secondary safety valve (28) by a gas inducting passage (29). When a gas cylinder (1) is charged with a gas, a gas charging mouthpiece (14) is attached to the gas outlet (5). Thereupon, an opening or closing portion (A) provided in the gas inducting passage (29) is closed by an actuating portion (30) provided in the mouthpiece (14). Thereby, a high-pressure gas is not released from the secondary safety valve (28).

Abstract: A mounting plate (20) is positioned between a manifold (18) and a pair of fluid pressure transmitters including a differential pressure transmitter (22) and a gauge pressure transmitter (24). The fluid pressure from high and low pressure taps or lines (14, 16) placed on opposite sides of a flow restriction (12) of a main flow line (10) is measured and transmitted to a remote location by the transmitters (22, 24). The mounting plate (20) has low and high pressure ports (62, 64) for differential pressure transmitter (22) and a low pressure port (66) for a gauge pressure transmitter (24). A connecting fluid passage (68) connects the low pressure ports (62, 66) and a block valve (80) is movable between open and closed positions to permit or block fluid communication between the ports (62, 66) and fluid communication between the transmitters (22, 24).
