Abstract: A hydraulic-metering, multiple-valve device for use primarily in a sprinkler system associated with large parcels of land. The valve device comprises a valve housing having an inlet and a plurality of outlets, wherein each outlet is controlled by corresponding valve means disposed within said housing and each valve means communicates with a flow channel having a drive means operably disposed therein and in direct alignment with the inlet of the housing. There is a timer-sequential metering means having a gear train interconnected between a sequencer drum and the drive means for controlled rotation of the drum, the drum being provided with a plurality of pins positioned and mounted to the surface thereof which cooperate with individual valve-actuating mechanisms, to selectively open and close the individual valve means as the drum rotates. By selecting the number and location of the pins, the sequence and time of operation of each valve may be readily selected.

Abstract: The invention provides an improved animal identification tag for attachment to the ear of an animal, which stands up when attached to the ear to provide for improved readability. The tag is of one-piece construction, and is easily inserted. The tag has a flat information-carrying portion having a surface on which indicia may be placed, and a pin extending outwardly from the edge of the information-carrying portion in a direction generally parallel to the surface. The end of the pin has laterally extending, resilient, flexible prongs forming a spear-shaped portion which passes through the ear of the animal and retains the tag in the ear. To retain the tag in an upright position, the tag is provided with a pair of flexible, resilient support members extending outwardly from the information-carrying portion adjacent to the shaft. These support members are positioned to contact the surface of the ear of an animal when the prongs and end of the shaft are passed through the ear.

Abstract: An improved method and tool for installing an identification tag into the ear of an animal. The tool comprises a handle portion and an elongated insertion portion having an end portion with a flat top surface and opposed blunt edges converging to form a sharp piercing tip. The tool also has engagement means for engaging a portion of an animal identification tag which is to be forced through the ear. In carrying out the method, the pointed tip and blunt edges are forced through the ear of an animal to pierce and stretch the tissue, and to create an opening. A portion of the identification tag is passed through the opening, and the tool is withdrawn while leaving the tag in place.
