A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

Abstract: Core-sheath filaments comprising cores including a polymer and 1 wt. % to 10 wt. % of a blowing agent, that can be dispensed as the core in a core-sheath construction. Dispensed adhesive compositions comprising the disclosed core-sheath filaments, the dispensed adhesive composition being a product resulting from compounding the core-sheath filament through a heated extruder nozzle. Methods of preparing core-sheath filaments.

Abstract: The disclosure is generally directed to a method of manufacturing an abrasive rotary tool using a molded elastic layer. A mold includes a cavity with a peripheral surface. An abrasive sheet is positioned so that a working surface of the abrasive sheet is positioned along at least a portion of the peripheral surface. A spindle is positioned within the mold to create a region between the spindle and the abrasive sheet. An elastomeric precursor material is injected into the region and solidified to form an elastic layer. As a result, the elastic layer is in direct contact with at least a portion of the opposed surface of the abrasive sheet and at least a portion of the exterior surface of the spindle. In this way, an abrasive rotary tool may be manufactured without using adhesive layers and/or fastening means.

Abstract: Methods and systems of delivering liquid additives in a molding system are provided. A charging sensor is provided to monitor the status of the injection charging mechanism of the molding system which charges, meters or doses an injection volume of molding material. A dosing instruction is generated based on the charging status signal. The additive pump controls the delivering of the liquid additives into the injection unit based on the dosing instruction, while the injection charging mechanism is charging the injection volume of molding material.

Abstract: A method of making an article is provided, including placing at least a portion of a panel in an injection molding die and overmolding at least one molded structure on a surface of the panel in the injection molding die, wherein the molded structure includes a foam composition. An article is also provided including a material-to-material connection between the surface of a panel and a molded structure. The panel includes first and second layers and a core disposed there between, wherein the core has a plurality of walls providing a series of connected cells. Some of the cell walls have openings providing fluid communication between a series of at least 3 cells, and the opening in a cell wall has an area that is at least 50 percent of the area of a side of that cell wall. Articles such as panels, walls, or other parts with curved surfaces can be formed according to certain exemplary embodiments. The articles are useful for absorbing sound in a designed frequency range.

Abstract: Polymeric foam layer having a thickness up to 25,700 micrometers, having first and second opposed major surfaces, and comprising foam features extending from or into the first major surface by at least 100 micrometers, and having a Tg in a range from ?125° C. to 150° C., wherein the first and second opposed major surfaces are free of exposed internal porous cells (i.e., less than 10 percent of the surface area of each of the first and second major surface has any exposed porous cells) and wherein at least 40 percent by area of each major surface has an as-cured surface; and methods of making the same. Exemplary uses of polymeric foam layers described herein including a finishing pad for silicon wafers and vibration damping.

Abstract: Panels comprising first and second layers and a core disposed there between, wherein the core has a plurality of walls providing a series of connected cells, wherein some of the cell walls have openings providing fluid communication between a series of at least 3 cells, and wherein the opening in a cell wall has an area that is at least 50 percent of the area of a side of that cell wall. Exemplary embodiments of panels described herein can be formed articles such as panels, walls, or other parts with curved surfaces. In one exemplary method, panels are shaped via thermoforming. In another exemplary method, panels are shaped via insert molding to provide the article. In another exemplary method, panels are shaped via compression molding to provide the article. The panels are useful for absorbing sound in a designed frequency range.
