Abstract: A practice target that includes: a front face; a rear face; a side face with a plurality of pockets, including first and second sets of pockets into which are disposed first and second sets of magnets. The first and second sets of magnets are identical in shape but are oriented opposite each other so that when the practice targets are stacked they have mutual attraction instead of being repelled by like magnets. The magnets include notches/cutouts/protrusions/etc. that match with similar structures in the pockets to hold them in place in the pockets. There are off-center pin holes through the magnets that make sure that they are oriented correctly during injection molding. There are netting grooves between the plurality of pockets and a tether aperture with a tether for attaching to a net.

Abstract: A system for cleaning contaminants from a body of water includes a dam that restricts a flow of water in the body of water. The system also includes a generator that generates electric power from the body of water, and one or more electrodes that induce an electrocoagulation current upstream of the dam. A filter press then removes contaminants that are precipitated from the water of the body of water by the electrocoagulation current.

Abstract: A module for electrocoagulation of contaminated water includes a first treatment chamber that submits the contaminated water to a first electrocoagulation current, and a second treatment chamber that submits the contaminated water to a second electrocoagulation current. The module also includes an intermediate chamber between the first and second treatment chambers that collects foam and precipitates from the first and second treatment chambers and that provides a passage for water exiting the first treatment chamber and entering the second treatment chamber.

Abstract: Technologies are described related to third party email signature generation and authentication. A DKIM signature may be stamped in a way such that the “From” address is encoded in the selector. The domain may be extracted from the DKIM signature based upon being from a known sender in the d=field, which signs on behalf of another domain. The reconstructed domain may be aligned from the selector against the actual domain in the “From” address to pass DMARC.

Abstract: A portable target assembly for use in a sport wherein a projectile is propelled at a goal, the portable target assembly comprises a front face and rear face separated by a solid material, and a magnet secured to the portable target assembly allowing the portable target assembly to be magnetically attached to a goal post or crossbar. A magnetically receptive material is coupled to a goal post or crossbar when the post or crossbar is not made of a magnetic material. 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 scan management system may configure various workloads and data streams within those workloads to be directed to various scan engines. The scan management system may be updatable and configurable by receiving a catalog of available scan engines and configuring the workloads and scan engines according to a policy that may be locally created and managed. The scan management system may be capable of reconfiguring the scan engines, including upgrading, adding, deprecating, and changing scan engines while being fully operational. In some cases, a single data stream may be scanned by two or more different scan engines, and a single scan engine may be used to scan two or more different data streams.

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 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: The present application relates to a hybrid air brake actuation. One hybrid air brake actuating system for controlling communication of pressurized air from an air supply to a vehicle brake includes a hydraulic control component and a hydraulic to pneumatic actuating arrangement. The hydraulic control component provides brake control signals through hydraulic fluid based on a force applied to a brake control, such as a brake pedal. The hydraulic to pneumatic actuating arrangement controls communication of pressurized air from the air supply to the vehicle brake based on the brake control signals.

Abstract: A pneumatic brake system that includes at least one pneumatic latching valve; a single device, such as a solenoid, for providing momentary pilot signals to pneumatic latching valve; a source of pressurized supply air in communication with the pneumatic latching valve; a spring brake or other pneumatic device in communication with the pneumatic latching valve; and, optionally, an indicator device for monitoring and displaying the state of the pneumatic latching valve. Upon receiving a first momentary pilot signal the pneumatic latching valve changes from closed to open and delivers pressurized air to the spring brake. Upon receiving a second momentary pilot signal, the pneumatic latching valve changes from open to closed and exhausts pressurized air from the spring brake to the external environment. The valve remains “latched” in its current state until the signaling device is energized and the next momentary pilot signal is received.

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.
