Abstract: A reinforced mine ventilation seal anchored with steel dowels into the strata of a mine passageway. The seal has a pair of metal mats formed of vertical and horizontal elongated reinforcing members which are sandwiched between a row of dowels set into the floor and ceiling of the passageway and extending into the passageway. The metal mats and the dowels are encased in a structural material such as concrete to form a seal which is capable of bidirectionally withstanding an overpressure due to an explosion. The dowels provide shear reinforcement and the metal mats provide flexural strength.

Abstract: An apparatus for controlling an internal pressure of a hermetically sealed chamber at a prescribed pressure level serves to relax pressure changes in the hermetically sealed chamber. The chamber is connected to an inlet passage for supplying air from an external environment through an aseptic filter, an outlet passage for discharging a gas through an aseptic filter, and an inlet valve and an outlet valve for selectively opening and closing the inlet passage and the outlet passage, respectively. The apparatus also includes a controller for controlling the inlet valve and the outlet valve to keep the internal pressure of the chamber at a prescribed positive pressure level. An elastic membrane of silicone rubber which is expanded or retracted depending on a change in the internal pressure of the chamber to relax the pressure change is connected to the outlet passage between the aseptic filter and the outlet valve.

Thus, when the locking sleeve is inserted into the elastic sleeve, the second magnetic member is attracted magnetically by the first magnetic member so as to position the locking sleeve in the elastic sleeve and to position the spout onto the distal end of the bent tube.

Abstract: A valve device includes: a valve member that controls flow of a fluid, and a body that has a valve insertion hole in which the valve member is inserted, and whose inner surface is cylindrically formed, and into which the fluid flows, and a lead-in passage that has an opening in the inner surface of the valve insertion hole, and that causes the fluid to flow into the valve insertion hole. A line representing the direction of extension of the lead-in passage is tilted from a line normal to the inner surface of the valve insertion hole at a position of the opening of the lead-in passage, in a view in the axis direction of the valve insertion hole.

Abstract: A split flow valve arrangement comprising a first valve portion having an inlet, a first outlet and a second outlet; and a second valve portion having a first inlet coupled to the first outlet, a second inlet coupled to the second outlet, a main outlet and a secondary outlet. The inlet is selectively coupled to none, one or both of the first and second outlets; the first inlet is selectively coupled to the main outlet and the second inlet is selectively coupled to the secondary outlet. The first and second valve portions are constrained to move in synchronicity to therefore selectively direct fluid to flow from the inlet to none, one or both of the main and secondary outlets.

Abstract: A pinch valve has a pinch bar constructed and arranged to translate between two different positions when the pinch bar lies in any orientation. The pinch bar is comprised of two orthogonal legs, one of which extends through and rotates inside a hole formed into a body for the valve. Having the pinch bar rotatable enables the pinch bar to be rotated away from where it would open and close a flexible tube.

Abstract: A valve includes a housing defining a bore having an inlet and extending along a longitudinal axis. A head is attached to the housing and defines a head passage having an outlet. A piston is disposed within the bore and includes a piston passage extending through the piston along the longitudinal axis. The piston is moveable between a closed position in which a sealing end of the piston abuts a seat of the head to close fluid communication through the piston passage and an open position in which the sealing end of the piston is axially spaced along the longitudinal axis from the seat of the head to permit fluid communication through the piston passage between the inlet and the outlet. The housing defines an equalizing chamber in fluid communication with the head passage for damping movement of the piston.

Abstract: A self cleaning valve assembly includes a valve body having an internal valve cavity. A cylinder member received in the valve cavity has a first sealing surface and a cylinder wall, and divides the valve cavity into a liquid-free cavity portion and a flow cavity portion. A spindle includes a spindle body contacting the first sealing surface to continuously prevent pressurized fluid in the flow cavity portion from entering the liquid-free cavity portion. A spindle piston end has a wiper member in a receiving groove frictionally contacting the cylinder wall. A handle pinned to the valve assembly directly contacts the piston end. Handle rotation displaces the spindle from a valve closed to a valve open position permitting pressurized fluid flow into the flow cavity portion. The wiper member wipes a contaminant off the cylinder wall and further prevents contaminant entrance into the liquid-free cavity portion.
