A seaming system for forming a seam is disclosed, wherein the seam consists of at least two opposed sections of high-modulus, high-tenacity, low-elongation fabric sections joined by a tape. The system comprises a seamer head, and a seamer base that includes a topography configured to impart a predetermined pressure gradient to the adhesive layer, tape, and fabric sections of the seam. The resultant seam has a cross-section or thickness profile that generally corresponds to that of the applied pressure gradient. As such, the constructed seam more efficiently distributes stress imparted from any applied load.

An optical flow is disclosed having a shell with a first portion and a second portion. The first portion provides a light entry aperture, and the second portion provides an imaging aperture. An inlet tube and an outlet tube are retained between the first portion and the second portion. A viewing assembly is retained between the first portion and the second portion. The viewing assembly includes a reference plate and a flow channel. The flow channel fluidly communicates with the inlet tube and the outlet tube. The reference plate extends from the shell to serve as a repeatable reference point for properly positioning the optical flow cell.

An optical flow cell includes a housing having an inlet coupled to an outlet through which a sample fluid material flows. A viewing assembly, carried by the housing, includes a pair of opposed plates having a gap therebetween which is in fluid communication between the inlet and the outlet. One of the plates extends outwardly from the housing for use as a reference point in a fluid sampling device. The flow cell is positioned between a light source and an imaging system to detect particle shape and size as the fluid passes through the viewing assembly.
