Abstract: The present disclosure is generally directed to biopolymers having coiled nanostructures, methods of making those biopolymers, and applications involving those biopolymers. Biopolymers having coiled nanostructures may be produced through a biophysical process by which the shape of a biopolymer macromolecular chain is altered. Biopolymers having coiled nanostructures may then be cross-linked to prepare biopolymeric networks. The biopolymeric networks may be configured to incorporate solid particles, in which they serve to hold the solid particles together against external stresses, solvents, and the like. For this reason, the biopolymers having coiled nanostructures are useful in a variety of applications, including in an improved process for forming iron ore pellets.

Abstract: An elevator trench drain includes a trench and a drain passageway. The trench has a base wall with peripheral side walls extending upwardly therefrom to define a trench volume therein. The drain passageway extends downwardly from the base wall of the trench and places the trench volume in fluid communication with a lower opening of the drain passageway. The drain passageway has a first section proximate the base wall defining a first cross-sectional area and a second section distal the base wall defining a second cross-sectional area. The second cross-sectional area is less than the first cross-sectional area and this reduction in cross-sectional area produces a head pressure that increases the flow out of the lower opening.

Abstract: A winch is employed for deploying a probe to a precise depth within a water column for making and recording physical measurement within such water column. More particularly, the winch rapidly unspools a line from an underway vessel, while maintaining minimal but constant line tension, as a probe, tethered to such line, descends within the water column in a "near" free-fall to a predetermined depth and then stops. The line lacks means for communicating its depth to the winch. The probe achieves a predictable descent behavior, even though it is tethered by a line to a winch onboard an underway vessel of unknown velocity and in variable weather conditions. The predictable descent behavior is achieved by maintaining a. minimal constant tension on the line within a narrow range. The descent behavior of a probe in "near" free-fall has sufficient predictability to construct an algorithm to correlate descent time with depth.
