Abstract: The use of select knitting processes allow the production of a cap liner with a separate eye opening and several distinct mesh structures that are individually designed to enhance the comfort of the eyes, nose, and mouth of the wearer.

Abstract: The present invention generally relates to layered embroidered headwear and methods for producing layered embroidered headwear. More particularly, the embroidering method of the present invention can produce headwear, including cap panels for producing the headwear, that comprises vivid decorations and designs, which are highly breathable and lightweight. As described herein, the embroidering method of the present invention can apply multiple levels of embroidering thread on top of each other to produce elaborate patterns or designs on the headwear without jeopardizing the breathability or weight of the headwear.

Abstract: Particles suspended in a fluid carrier are differentially separated by, first, grading the particles into fractions of equal settling rates and, second, separating the equal-settling particles of each fraction according to the magnetic susceptibilities of the particles. The particulate sample to be separated is passed through a two-path parallel flow system. In one path, the sample is selectively graded, by elutriation, into equal-settling fractions. Each such fraction then flows directly to the second path, where it crosses a magnetic field at a velocity proportional to its settling rate. Such proportionality between settling rate and flow velocity provides a residence time which ensures that the degree of deflection, in response to gravitational and magnetic forces, required for separate recovery of magnetic particles, on the one hand, and non-magnetic particles, on the other hand, will be attained within the active length of the magnetic field.
