Abstract: A showerhead assembly that includes a showerhead housing, a distributor, and a valve layer. The showerhead housing includes a top plate, a bottom plate, and a plurality of sidewalls extending between the top plate and the bottom plate, where the top plate includes a fluid inlet configured to couple to a fluid source. The distributor includes at least one distributor outlet, and is situated in the showerhead housing. The valve layer includes at least one valve assembly, and is situated in the showerhead housing. The at least one valve assembly is coupled to the bottom plate. The at least one channel of the distributor is further configured to disperse fluid from the fluid inlet to the at least one distributor outlet, and the at least one distributor outlet is coupled to, and configured to disperse fluid to, the at least one valve assembly of the valve layer.

Abstract: A needle holder is described, comprising first and second handles. Each handle comprises a finger loop at a proximal end of the handle, an arm fixedly attached to the finger loop, extending toward a distal end of the handle and defining a longitudinal axis, and a jaw fixedly attached to the arm, extending along the longitudinal axis toward the distal end of the handle. The needle holder further includes a sliding pivot joint connecting the first and second handles at a connection point between the arms and the jaws, the sliding pivot joint configured to allow the first and second handles to move rotationally with respect to one another about a rotational axis orthogonal to the longitudinal axis at the connection point, and/or translationally with respect to one another along the longitudinal axis. A method of grasping a needle is also described.

Abstract: This application relates to thiophene azo dyes for use as hueing agents, laundry care compositions comprising such thiophene azo dyes, processes for making such thiophene azo dyes, and laundry care compositions and methods of using the same. The thiophene azo dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. These thiophene azo dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. The thiophene azo dyes are also generally stable to bleaching agents used in laundry care compositions.

Abstract: The present application relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two constituents: at least one chromophore constituent and at least one polymeric constituent. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to light, or they may absorb light to reflect these same shades. This disclosure also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.
