Abstract: The present invention overcomes the shortcomings of the current trial and error method in deflating tires. The controlled tire deflation valve system allows for tires to automatically and accurately deflate to the desired pressure. The present invention comprises a shaft, a spring and a piston wherein the shaft runs through the spring until the spring rests on the shaft spring seat. The shaft spring seat is effective in restricting the movement of the spring.

Abstract: The invention relates to a device for securing a leak of fluid from equipment containing a pressurised fluid. The device comprising a gas-tight containment device disposed around the equipment and defining a volume, Vconf, between the inner surface of the sealed containment device and the outer surface of the equipment. A vent is formed by one or more ports in the sealed containment device, each port being defined by its cross-section and shape. According to the invention, the volume, Vconf, the cross-section and the shape of each port are configured such that, in the event of a leak of flow rate Qf, the fluid is discharged through each port in the form of a turbulent jet.

Abstract: In one featured embodiment, a closure sleeve for a valve comprises a sleeve body surrounding a center axis and defined by an overall length extending from an upstream end to a downstream end. The sleeve body has an internal cavity that is enclosed at the downstream end and is open at the upstream end. The internal cavity is defined in part by a piston contact surface that is defined by an inner diameter. The piston contact surface is configured to slide against a piston to be received within the internal cavity, and a ratio of the inner diameter to the overall length is between 1.0 and 1.5.
Abstract: The invention is directed to a valve for a compressed gas cylinder, comprising: a valve body with an inlet, an outlet and a passage connecting the inlet with the outlet; a shut-off device of the passage with an actuating pin extending in the passage; a check-valve between the shut-off device and the inlet, the check valve comprising a seat and a movable closing member initially held at a position distant from the seat by contact with a guiding surface and movable past the position by the pin so as to cooperate with the seat and prevent a refilling flow of gas from the outlet to the inlet. The guiding surface is on a tubular portion fixed to the valve body and comprising at least one radial aperture so as to allow the refilling flow of gas to by-pass the closing member when in the distant position.
Abstract: A valve assembly (1) which is intended for differentiated individual control of the movement mechanisms of an IS machine and can therefore be used in a modular manner consists of a valve support (2?) and a head part (22) which supports two pilot control valves (3, 5), two safety valves (4, 6) and two switching valves as one assembly. By way of actuation of the safety valves (4, 6), the feed of control air to the switching valves can be interrupted, which switching valves are assigned, for example, to the opening movement and the closing movement, respectively, of a closing cylinder which is assigned to a preform. The valve assembly has interfaces for connection of control and operating air and for electric connection to a machine controller. If required, the assembly which is designed in this way makes it possible to interrupt the control air in a differentiated way which is related to an individual track, in addition to simple assembly and dismantling.

Abstract: A gate valve for positioning in the open upper end of a grain bin below the lid thereof which closes the open upper end of the grain bin. The gate valve permits grain to pass downwardly therethrough but which prevents warm moist air from the grain bin from passing upwardly therethrough into a grain spout or deadhead box.
Abstract: Techniques and mechanisms for changing a flexibility of a sheet structure. In an embodiment, a garment or other device includes sheet structure, where an interface region is disposed between overlapping layer portions of a sheet structure. While a pressure differential is maintained between the interface region and a chamber of the garment, a valve of the garment is opened to allow an exchange of fluid between the interface region and the chamber. In another embodiment, the exchange of fluid changes a flexibility of the sheet structure by initiating or alleviating friction jamming between the overlapping layer portions.
Abstract: A valve assembly for a variable frequency generator includes an input shaft extending about a longitudinal axis and having a bore defined therein. Also included is a disconnect shaft extending about the longitudinal axis and disposed in abutment with the input shaft. Further included is an oil restrictor disposed with the bore of the input shaft. Yet further included is a vent valve disposed within the bore and in abutment with the oil restrictor, the vent valve comprising an angled wall, the angled wall partially defining an annulus. Also included is a plurality of ball bearings disposed within the annulus, the plurality of ball bearings sliding radially outwardly away from the longitudinal axis during rotational operation of the input shaft to apply a force on the angled wall of the vent valve to bias the vent valve axially into a sealed condition.

Abstract: Apparatuses regulate the flow of fluids, such as, for example, water or other like fluids, through pipes. The apparatuses comprise a poppet valve having a spheroid-shaped valve portion and one or more shims for adjusting effective spring length during use thereof. Specifically and without being bound by theory, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for regulating the flow of fluids within a pipe are further provided.
Abstract: Methods, medium, systems, and a network device (or node) are described for enhanced power notification from a node, such as an ID node, in a wireless node network having a master node and a server. The ID node is capable of communicating directly with the master node but incapable of communicating directly with the server. In general, the ID node detects a current power status for the ID node and determines a current location of the ID node. The method then has the ID node broadcasting an enhanced power alert notification when the current power status of the ID node is below a threshold. The enhanced power alert notification indicates that the current power status of the ID node is below the threshold and includes the current location of the ID node.
