    Abstract: An analysis system for determining one or more operating conditions of a metal electrolysis cell and for facilitating a response is provided. The analysis system comprises a bath probe electrically interconnected to a portable computing device. The bath probe generates signals associated with temperature measurements produced from thermal communication with an electrolysis cell bath. The portable computing device may receive these signals and generate data based thereon. The data may be transformed into operating condition information relating to the electrolysis cell.

    Abstract: Horizontal duct scrubbing systems for removing particulate matter from a gas are disclosed. The horizontal scrubbing systems may receive a particulate-containing gas stream (e.g., containing PM10 and/or PM2.5 particulate matter), and remove at least some of such particulates by spraying liquid droplets co-current to the flow of the gas stream, where the liquid droplets have a volume median droplet diameter (DV0.5) of from 240 microns to 600 microns. The scrubbing system may be substantially free of flow deflection members between a liquid inlet manifold and a demister. The system may be remove at least 50 wt. % PM10 and/or PM2.5 particulate matter from the gas stream.

    Abstract: Porosity of aluminum ingot can be evaluated using focused beam ultrasonic testing and/or florescent dye penetrant testing. The aluminum ingot can be machine cut to form an aluminum ingot slice prior to testing. The machine cut can be performed using a polycrystalline cutting material in a “fly cutter” configuration. The polycrystalline cutting material can comprise a diamond material. The insert can cut an aluminum ingot slice to a surface roughness finish in the range of about 7-9 micro inches.

    Abstract: A blind fastener including a pull-type core bolt having a shank with a head, and a sleeve having an elongated body with a head, and a tapered notch formed within an exterior surface thereof and defined by a tapered portion having a slope and a frictional enhanced surface. The core bolt is installed within the sleeve. During installation of the fastener within the plurality of work pieces, an axial force is applied to the core bolt the head of the core bolt engages the sleeve, and a bulb is formed on the elongated body of the sleeve, the bulb defining a portion of a bulbed portion. When a selected axial force is reached, the bulbed portion separates from the elongated body and engages axially the tapered portion of the sleeve, increasing the diameter of the bulb which engages a blind side of one of the work pieces.

    Abstract: A pin latch includes a guide block, a handle having a trigger, and a shear pin housed slidably within the guide block and connected to the handle. The shear pin includes a catch-pin engageable by the trigger, and is slidable between an engageable position and a disengageable position when the handle is moved from a closed position to an open position. Alternately, the pin latch includes a bracket connected to the shear pin and includes a catch-pin, and the handle is moveable to an intermediate position, such that a trigger is disengaged from the catch-pin and the shear pin engages a stop pin. A guide block spring acts on the stop pin to retain releasably the handle in its intermediate position. The guide block includes a finger and the shear pin includes a groove sized and shaped to receive the finger when the pin latch is in an unlatchable position.
