Abstract: There is provided a service valve for use at an irrigation sprinkler. The service valve enables water flow into the sprinkler to be controlled from above a buried irrigation sprinkler. The service valve enables maintenance of internal components of the sprinkler without having to turn off a service valve that is remotely located from the sprinkler.

Abstract: An applicator made from stainless steel comprising an elongated handle, a chamber, and a blade. The handle having a longitudinal axis and comprising a first end and a second end, a first section, a second section, a third section, and a fourth section, each in substantial alignment along the longitudinal axis of the handle. The chamber is substantially cylindrical and is coupled to the first end of the handle for collecting a calibrated volume of material. The chamber has an open end distal to the first end of the handle and a closed end proximate the first end of the handle, and is in substantial alignment with the longitudinal axis of the handle. The blade is coupled to the second end of the handle, the blade having a curved profile and a tip with a rounded facial contour, and being in substantial alignment with the longitudinal axis of the handle.

Abstract: A container tapping device for use with a container containing liquid contents. The device comprises a proximal end portion, a middle portion, a distal portion and a distal end portion. The proximal portion comprises a proximal surface, a distal surface, and a central bore capable of being in fluid communication with the liquid contents of the container. The middle portion comprises a locking chamber and one or more middle portion orifices, the orifice(s) capable of being in fluid communication with the central bore as well as the liquid contents of the container when the device is engaged with the container. The distal portion comprises a recess in one or more of the faces of the distal portion. The distal end portion comprises a point portion formed by an apex area of the distal portion, the point portion capable of puncturing the container and protruding therein.

Abstract: A method for forming a pigmented aqueous slurry includes a step of combining a dispersant having pigment affinic groups with water to form an aqueous dispersant mixture. Pigment is added to the aqueous dispersant mixture to form an aqueous pigment mixture. The aqueous pigment composition is ground until the average particle size is less than 30 microns to form a pigmented aqueous slurry.

Abstract: A method and system for determining a level of vapor generated by an evaporative system. The evaporative system is closed to atmosphere. An initial pressure in a fluid-filled tank is sensed and, after a predetermined amount of time, a second pressure in the tank is sensed. A pressure difference is determined based on the sensed initial pressure and the sensed second pressure. The level of vapor generated by the evaporative system is determined based on the pressure difference.

Abstract: A lineman's pliers which is designed to push or pull a snake through a conduit or tubing with less effort and time due to the provision of special gripping and alignment means that do not crimp the snake and apply more effective gripping action. The pliers include a pair of crossed levers provided with a head at one end having front and rear pairs of opposing jaws and opposing elongated handles at the other end whereby said jaws may be operated to effectively grip a snake.
