Abstract: A caustic paste applicator provides a self-contained adhesive patch that supports a ring of adhesive that is adhered to the calf s skin around the horn bud and an inner spot or dab of caustic paste that is applied over the horn bud to contact the horn bud. The patch shields the caustic paste from spreading and allows the adhesive to be used in conjunction with the caustic paste in a manner which does not cause the patch to lose its stickiness.

Abstract: A composite material includes biodegradable and/or renewable materials such as purified milk protein recovered as a byproduct in cheese making processes. The result is a material suitable for three-dimensional (3D) printing and extrusion based polymer processing, with improved properties but that is still environmentally friendly. Purified milk protein may be used to produce composite thermoplastic materials or resins. Additional chemical modification may improve the blending of purified milk protein.

Abstract: A polylactic acid (PLA) composite material includes biodegradable and/or renewable materials such as purified lignin recovered as a byproduct in organosolv processes. The result is a material suitable for additive printing, with improved properties but that is still environmentally friendly. A coupling agent such as silane, diisocyanate crosslinking agent, and reactive extrusion agent may improve the blending of polylactic acid and purified lignin. Additional filler materials such as fibers or their powders may be added to significantly improve the mechanical properties of three-dimensional printed objects.

Abstract: A three-dimensional (3D) printer system includes a nozzle that can passively align fibers being deposited with resin while creating fiber-reinforced composite components. The nozzle may include a nozzle body with main bore that directs material axially through a nozzle body, toward an alignment duct that provides the nozzle's outlet. The alignment duct may provide a passage in which the fibers are urged into a different orientation aligns the fibers generally parallel to each other in a different direction than the axial flow direction through the nozzle. The alignment duct's passage may be radially asymmetric, such as a tapering rectangular slot(s), which may provide guide surfaces to impart the reorientation of the flowing fibers.

Abstract: An intrauterine device (IUD) is insertable into a uterus of a mare to suppress estrus and estrus-related behaviors in mares. The IUD may take the form of a weighted ball or sphere that is biocompatible and includes a string attached to the weighted ball for ease of removal by pulling down on the string.
