Abstract: A process control valve comprises a valve body having an inlet and an outlet and a plug. The plug selectively restricts fluid communication between the inlet and the outlet. The plug can have a plug body and a plurality of fins extending radially outward from the plug body between a first end of the plug and a second end of the plug. Each one of the plurality of fins can have a tapered section proximate the second end of the plug. The tapered section can taper radially inward toward the second end of the plug.

Abstract: A composition for killing an animal, e.g. a rodent, comprising: (i) a toxin component comprising one or more agents toxic to the animal, e.g. cholecalciferol or 25-hydroxycholecalciferol (vitamin D3); and (ii) a carrier system for the toxin component; wherein the carrier system (ii) comprises: (a) at least one solvent or dispersant for the toxin component, e.g. an alcohol such as ethanol, and (b) at least one dermal disruptant component, e.g. dimethylsulfoxide (DMSO). The compositions provide enhanced dermal penetration of the toxin into and through the skin of the animal onto which the composition is sprayed or delivered, e.g. in a trap or other apparatus.

Abstract: A method for printing programs and/or data from a handheld or remote computer 101 to each one of a plurality of printers 109, includes providing a secondary computer 105 having a plurality of printer drivers that facilitate the printing of the remote computer programs and/or data by one or more of the printers 109, sending the remote computer program from the remote computer 101 to the secondary computer 105 via an interface 103, and providing an interface 107 between the secondary computer 105 and the plurality of printers 109.
