Abstract: A quick-release connector structure for an air tank includes a connector body incorporated with an air tank and a seat block. The seat block is secured to the air tank and comprises a valve having a post extending forwardly. The valve is acting as a switch to turn the air tank on and off. The connector body comprises a first passage and a second passage. The first passage comprises an air release hole and a through hole. A thimble is disposed in the first passage. A quick-release wrench is provided in a recess disposed on the connector body. The quick-release wrench corresponds to the through hole and is secured by a fastener. By turning the quick-release wrench, the high-pressure air remaining in the pipe is released.

Abstract: A valve is disclosed that is operable by converting rotational force of a stem into linear motion of a valve closure element, such as a sleeve, to control fluid flow through the valve. In a presently preferred embodiment, at least two interconnection members are rotatably mounted, such as with a round end, to a stem drive element. The interconnection members are slidably mounted into channels or grooves in a sleeve. Rotatable movement of the stem permits rotation of the interconnection members whereby the interconnection members are constrained to slide in the channels whereby rotational movement of the stem is converted into translational or linear movement of the valve closure element.

Abstract: A memory device includes memory cells, bit lines, active area lines running generally in parallel to the bit lines, and transistors formed in each active area line and electrically coupling memory cells to corresponding bit lines. Each bit line includes slanted portions that intersect a corresponding portion of an active area line at an angle. Contacts electrically coupling the bit line to portions of the active area line are formed in a region generally defined by the angled intersection of the bit line to the active area line. The memory cells can have an area of about 6F2, and the bit lines can be coupled to sense amplifiers in a folded bit line configuration. Each bit line includes a first level portion and a second level portion.

Abstract: A modulating valve includes an inlet passage and a discharge passage, both of which are in communication with an internal cavity associated with the valve body. An actuator arrangement includes a pivoting actuator shaft, at least a portion of which is located within the internal cavity. A flow-controlling plug member includes a first portion extending into one of the passages, and a second portion located within the internal cavity. The first portion is provided with guide structure engageable with one or more walls defining the passage, to guide axial movement of the plug member. The second portion of the plug member is interconnected with the actuator shaft. The plug member second portion and the actuator shaft are interconnected in such a manner that pivoting movement of the actuator shaft results in axially inward or outward movement of the plug member within the passage.

Abstract: A butterfly actuator is provided and has a pair of spaced apart cams which move a valve stem wherein the cams are integral with a shaft having one portion having a generally cylindrical outer surface which is rotatably mounted in a bearing sleeve fixedly mounted in a housing mounted at a fixed location and wherein the bearing sleeve has a length which is between about 2.0 and 3.5 times the diameter of the generally cylindrical outer surface. A butterfly actuator is mounted on an end portion of the shaft so that movement of the butterfly actuator rotates the shaft and is formed from a metallic material to provide for an extended life period of useful operation.

Abstract: A shut-off valve to fit the outlet end of a double faucet single spout tap in lieu of the conventional aerator screen. The valve comprises a valve body having an upstream valve seat on which is adapted to rest a disc-shape valve plug. An operant shaft extends transversely through the valve body and is provided with a handle at one end to rotate the shaft. The shaft has a central cam lapping a downstream edge portion of the valve plug. In one rotated position of the shaft, the valve plug closes the valve under the action of the upstream fluid pressure. Rotation of the shaft causes tipping of the valve plug to a fully-open position.

Abstract: A fuel control valve construction, parts therefor and methods of making the same are provided, the construction having a housing provided with an inlet adapted to be interconnected to a fuel source and an outlet adapted to be interconnected to a burner. The housing has a main pressure regulator and a main valve operated by the main pressure regulator for controlling fuel flow from the inlet to the outlet to provide a full rated flow of fuel to the burner. The housing has a by-pass for interconnecting the inlet to the outlet to provide a fuel flow to the burner that is less than a full rated flow of fuel but is sufficient by itself to support combustion at the burner until the main valve provides the full rated flow of fuel thereto. The housing has a by-pass pressure regulator for controlling the flow of fuel through the by-pass independently of the operation of the main pressure regulator.

Abstract: A flow control apparatus having a valve body forming a longitudinal axis with an inlet and an outlet connected by flow passage that are all substantially disposed on the longitudinal axis to provide a straight flow path is disclosed. A moveable flow control sleeve is concentrically disposed about a cylindrical seat member fixed in the valve body. Radially opposed ports are disposed in the seat member. A quick acting 90 degree rotatable stem is operably connected to the flow control sleeve to reciprocate the sleeve axially along the cylindrical seat to and from the open and closed position to regulate the fluid flowing through the opposed ports and valve apparatus. A flowmeter sensor is mounted with the valve body for providing a signal in response to the rate of flow through the flow passage. The signal is usable by a flow rate determining system which may be connected to a valve actuator for automatically operating the valve in response to certain prearranged flow conditions.

Abstract: A flow-control valve assembly particularly useful in fire fighting apparatus comprising a contoured valve seat mounted axially within a valve body and a balanced tubular valve member reciprocably movable in the valve body coaxially with said valve seat for providing proportional flow control, manual valve actuating means for reciprocably moving the tubular valve member including a disc rotatably mounted in a bore formed in a lateral surface of the valve body on a pivot member on which a handle is pivotally mounted and a pin spaced from the pivotal member extending through the handle and the disc which engages in a circumferential groove formed in the outer surface of the tubular valve member for effecting reciprocable movement of the valve member when the handle is reciprocably moved. The disc can be made of deformable material and provided with means for expanding the disc to impart a braking action on the movement of the handle.

Abstract: A fuel control assembly includes a valve closure member, a fuel inlet restricting member, and a fuel outlet cleaning member which are connected together for simultaneous movement. The valve closure member is movable within a valve body by a crank pin on a rotatable valve control shaft, and the valve closure member is movable in both directions beyond a sealing position in which the valve closure member cooperates with the valve body to shut off fuel flow through the valve body. Movement of the valve closure member in one direction beyond the sealing position maintains the fuel flow path closed and moves the fuel outlet cleaning member into the fuel outlet orifice to clean the orifice.

Abstract: A crank-operated valve is provided wherein the valving member and stem are of deflectable plastic material. Sucn an arrangement permits a corrosion resistant, easily operating valve to be prepared using an imprecise valve body.

Abstract: A control device of the double lever-fulcrum type for controlling the opening and closing of a fluid valve includes a single solid shaft rotatably mounted and connected to a longer or power lever. A notch is formed in the shaft to provide a preferably flat surface, one end edge of which acts on the valve element to close the valve. The fulcrum of the device comprises the longitudinal axis of the shaft, and the shorter or thrust lever of the device comprises a radius of the shaft extending from the longitudinal axis to the one end edge of the surface formed by the notch.
