Abstract: An irrigation signal which has a cylindrical body to receive a cylindrical float, the body having an upper portion and a lower portion, the lower portion being adapted to extend below the bottom of the irrigation ditch in which it is installed in order to form a well in which irrigation water may enter in order to raise said float. A signal connected to said float by a rod is positioned in the top of the body, and upon the raising of said float is pushed from the top of said body and automatically extends to be plainly visible from a distance to signal that irrigation water is present in said ditch. When irrigation is stopped the water will drain from the lower end of the body so that the signalling float will lower and exert a downward pull on the signal. The signal will collapse and be pulled into the top end of the body into nonsignalling position.

Abstract: An apparatus for holding and monitoring an intravenous infusion container. A pulley wheel is rotatably mounted to a base and wrappingly receives a line which is connected to the intravenous infusion container for the suspended mounting thereof. The axle of the pulley wheel extends through a discshaped base having a plurality of markings thereon. A pointer is fixed and mounted to the axle adjacent to the base. The intravenous infusion container when full causes the axle to rotate so as to position the pointer adjacent to a marking. A spring returns the wheel and pulley wheel to an original position as liquid drains from the container.
