Abstract: Techniques for simplifying and reusing visual programming graphs are described herein. In some examples, visual programming graphs may be simplified by decoupling execution signals from data resolution. Execution of a particular node may be triggered through a representation of a signal sent from a signal output slot of another node to a signal input slot on the node being triggered. Additionally, evaluation of data values may be represented by a connection between a data output slot on the node providing the data value to a data input slot on the node receiving the data value. Another technique for simplifying visual programming graphs may include combining and/or collapsing of multiple selected visual programming nodes into a single reusable visual programming node. In some examples, reusable combined visual programming nodes may be exposed using unlocked versions and/or locked versions.

Abstract: Disclosed is a method of feeding an animal, such as swine. Generally, the method comprises administering humic acid and corn steep water to the animal in conjunction with feeding the animal, such as including humic acid and corn steep water with the animal's drinking water. Also disclosed is a composition that comprises humic acid and corn steep water solids, the composition being suitable for addition to an animal's drinking water. The disclosed method and composition are believed suitable for promoting animal weight gain.

Abstract: Disclosed is an animal feed composition that includes spent filter media and animal nutritive components. The spent filter media may be present in any suitable amount, such as about 0.1 wt. % to about 5 wt. % by weight. The spent filter media includes spent diatomaceous earth, organic carbon, activated carbon and water. Methods of promoting weight gain of animals by administering the animal feed composition are also disclosed. In some embodiments, feeding a herd of animals with the animal feed composition will promote weight gain in swine relative to an otherwise-similar animal feed composition that does not include spent filter media.

Abstract: A paddle handle latch includes a frame which defines a recess, and a peripheral handle which is mounted for pivotal movement in the recess. A retainer is mounted to the frame to define a channel having a latching axis and this retainer is shaped to receive a striker moving along the latching axis and to retain the striker against movement transverse to the latching axis. A catch is pivotably mounted in the retainer to move between an open position and a closed position. A linkage interconnects the paddle handle and the catch such that the paddle handle operates to move the catch between the open and closed positions.
