Abstract: Art paints or base materials can be manufactured from discarded materials such as architectural paint to reduce waste paint and to produce high quality art paints at a low cost and with a low ecological impact. Discarded architectural paint or other feedstock material is sorted, treated, and mixed with additives such as colorant, polymers, or monomers in a dispersion to produce a high-quality art paint. The high quality art paint can have selected traits, such as color, sheen, dry time, viscosity, or other properties, that are desirable for art paints but not traditionally present in the source feedstock materials.

Abstract: A food-safe composition and resulting article with grease and water resistance properties comprised of a petroleum wax based aqueous emulsion, a food-safe coating formulation, and an alkyl ketene dimer (AKD), wherein the composition exhibits grease and water resistant properties without a fluorinated compound present in the composition. A method of making the composition and a method of using the composition to form pulp molded articles such as food-safe containers and other pulp-based food packaging and utensils are provided.

Abstract: Provided are methods, apparatuses and washing machines that involve the filtration of microparticulate from liquid effluent of laundry apparatuses and systems. For example, steps involved in the inventive method may include: collecting the liquid effluent from the output of the outer tub of the washing machine; establishing a continuous high-pressure state to at least a portion of collected liquid effluent by a pumping device, based at least in part on a signal; and directing a threshold amount of high-pressure liquid effluent by a pumping device through a microparticulate filtration system, wherein the threshold amount is based at least in part on a first aspect of the pumping device and/or a microparticulate filtration system.

Abstract: A tool for separating blocks and other elements from an assembly of toy construction elements is disclosed. The tool may include a coupling end that can attach to pegs and/or openings in a block and is configured for easily prying off the block. The tool may include a moving member that can be used to configure the coupling end in two different configurations for coupling to either the top or bottom of a block.

Abstract: A method and an apparatus are provided for using a capacitor chain to perform charge sharing and Anger logic to determine, for charge pulses arising from gamma-ray detection, a row position along an array of scintillation-based gamma-ray detectors. Further, high-pass filters configured at the ends of the capacitor chain perform pulse shaping to preserve timing information. To determine the column position for charge pulses, a two-stage summing amplifier configuration is used with weighting amplifiers controlling the relative gain of the second-stage amplifier with respect to respective columns in the array. Each detector element in the array is a silicon photomultiplier (e.g., Geiger-mode avalanched photodiodes biased above breakdown voltage). Position information can be generated by Anger logic on four outputs from the second-stage amplifiers. Energy and timing information can be generated as a sum of the four outputs from the second-stage amplifiers.

Abstract: A food container is provided that has a formed cavity having top edge and two or more flaps coupled with one the top edge. Each of the flaps may extend half-way or more between opposite points of the container. The flaps may include a closure mechanism to secure the flaps in a closed position to provide a covering for substantially all of the area defined by the top edge, thereby closing the formed cavity. The formed cavity may include one or more radiused portions, with one or more of the flaps including a raduised extension that extends outwardly relative to a connection point between the flap and the cavity top edge. One or more of the flaps may include a recessed portion having a flap sidewall that is located adjacent to a formed cavity sidewall when the flap is folded to cover a top opening of the food container.
