Abstract: The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing and analyte characterization. Such polynucleotide processing may be useful for a variety of applications, including analyte characterization by polynucleotide sequencing. The compositions, methods, systems, and devices disclosed herein generally describe barcoded oligonucleotides, which can be bound to a bead, such as a gel bead, useful for characterizing one or more analytes including, for example, protein (e.g., cell surface or intracellular proteins), genomic DNA, and RNA (e.g., mRNA or CRISPR guide RNAs). Also described herein, are barcoded labelling agents and oligonucleotide molecules useful for “tagging” analytes for characterization.

Abstract: A weft separator device for shuttleless looms or the pick and pick type in which any one of a plurality of weft yarns from separate sources can, by positioners individual to each weft yarn, be located for insertion into a warp shed. The device includes a pivotally mounted finger member operatively associated with each of the positioners and is effective in providing positive separation between a selected weft yarn and those in their inactive positions in the area intermediate the edge of the woven fabric from which the weft yarns extend to their respective positioners.

Abstract: A control device for the weft yarn in shuttleless looms of the single pick insertion type having a selvage forming apparatus on the weft insertion side of the loom. The device includes a weft locating member which is effective in receiving and holding the weft yarn extending from a shed during movement of the loom's lay and reed toward beat-up position. The locating member positions the weft for reception by the selvage forming apparatus and by a cam member operatively associated therewith is effective in causing the weft to assume a position to affect its reception by the gripping element of the inserting carrier during movement of the lay and reed away from beat-up position.
