A method of sport training, comprising the steps of: providing a portable target assembly having a front face and a rear face separated by a solid material with a magnet secured thereto; securing the portable target assembly to a goal post or a cross bar of a goal such that the portable target assembly protrudes into a goal region of the goal; launching a projectile at the portable target assembly.
Abstract:
A valve (10) for controlling fluid flow to and from an actuatable device (30) includes a housing (34) defining a chamber (90) for establishing fluid communication between a fluid supply (14) and the actuatable device (30). A spherical ball (120) controls fluid flow through the chamber (90). The housing (34) has a housing seat (84) on which the ball (120) can be seated. A piston (100) movable in the chamber (90) in response to a control input has a piston seat (106) on which the valve element (120) can be seated. The valve (10) has an exhaust condition in which the ball (120) is seated on the housing seat (84) and is spaced apart from the piston seat (106), and a supply condition in which the ball is seated on the piston seat and is spaced apart from the housing seat, and a hold condition in which the ball (120) is seated on the housing seat (84) and the piston seat (106) is seated against the ball (120) simultaneously.
Abstract:
A pneumatic valve includes a housing having an inlet port and a delivery port and an exhaust port. A valve element is movable in the housing to control air flow between the inlet port and the delivery port and the exhaust port. The valve includes a rolling element actuator for converting a rotary actuation force to linear movement of the valve element.
Abstract:
An activated carbon filter is regenerated while it remains positioned in a filter vessel by first draining both unfiltered and filtered water out of the vessel and then applying an electric current through the activated carbon body of the filter to drive off contaminants. An inert gas is directed through the filter in a direction opposite to that of the liquid flow and then contaminants are moved from the filter vessel to a multi-stage catalytic converter where they are completely oxidized.
Abstract:
A water treatment tank for treating waste water using an electrochemical treatment process. The electrochemical process removes both suspended and dissolved solids and allows the treated water to be decanted from the treatment for reuse or discharge. The tank includes a tank housing with a first and second waste water receiving compartments. A waste water inlet line is attached to the top of the first compartment for filling the compartment with waste water. A side of the first compartment includes an opening for receiving an electrode assembly with a plurality of electrodes extending inside the compartment. The electrodes are attached to the power supply via electrode cables with the polarity of a current cycle reversed periodically depending on the types of water contaminates being treated. A filtrate sump is mounted in the bottom of the tank housing.
Abstract:
Insitu process equipment for the electrochemical treatment of contaminated water in a pit or lagoon such as an oil drilling reserve pit. The insitu process equipment uses a minimum of equipment for removing both suspended and dissolved solids in the water and allowing the treated water to be decanted from the pit or lagoon for reuse or discharge. The process equipment includes a floatation device in the form of a plurality of lightweight foam filled barrels rotatably mounted on drum axles. The drum axles are attached to an elongated barrel frame. A pair of electrode assemblies with a plurality of electrodes are attached to opposite sides of the barrel frame. The electrode assemblies are pivotly mounted on the barrel frame for lowering the electrodes below the water level when the process is in operation. An electrode cable guide is mounted on top of the barrel frame and the barrels for holding electrode cables. One end of the electrode cables are attached to opposite ends of the electrode assemblies. The other end of the electrode cables is attached to a power supply, such as a generator, resting on the shore and next to the pit or lagoon. The power supply provides direct current via the cables to the electrodes with the polarity of the current cycle reversed periodically depending on the types of water contaminates being treated. When the cycle is reversed, the contaminants gathered on the electrodes typically fall to the bottom of the pit as precipitated solids.
Abstract:
A distributed historian framework is provided where historical data is collected in accordance with an organizational model of a hierarchical system that is distributed across various elements of an enterprise. A directory service operates with the organizational model to enable configuration of historian components within the organization and to enable data to be located within the organization. In one aspect, an industrial automation system is provided. The system includes at least one historian component to archive data within an organization. A common data model then exposes functionality and data of the organization to the historian component.

Abstract:
A valve for use in a pneumatic fluid system, such as an air brake system, is disclosed. The valve provides for fast release of pneumatic fluid from the delivery cavity through the exhaust port upon cessation of flow from the pneumatic fluid reservoir through the supply cavity. The valve includes a flow diverter that restricts fluid flow from the delivery cavity to the supply cavity when pneumatic fluid pressure in the supply cavity is less than that in the delivery cavity with minimal restriction of flow from the supply cavity to the delivery cavity when pressure in the supply cavity is greater than in the delivery cavity.
Abstract:
A water treatment tank for treating waste water using an electrochemical treatment process. The electrochemical process removes both suspended and dissolved solids in the water and allows the treated water to be removed from the tank for reuse or discharge. The tank includes a tank housing with first and second waste water receiving compartments. The two compartments are identical and are used alternately when treating the waste water. A waste water inlet line is attached to the top of the first compartment for filling the compartment with waste water. A side of the first compartment includes an annular opening for receiving an electrode assembly with a plurality of electrodes extending inside the compartment for treating the waste water electrochemically. The electrodes are attached to the power supply via electrode cables with the polarity of a current cycle reversed periodically depending on the types of water contaminates being treated. When the cycle is reversed, the contaminates gather on the electrodes typically fall to the bottom of the tank as sludge and are drained into a removable filter basket. The compartments also include an airline connected to an air spray manifold. The air spray manifold is used for circulating air bubbles upwardly in and around the electrodes for providing a scrubbing effect and carrying away contaminates that might gather on the electrodes.
