    Abstract: A fire-extinguishant system includes a source of extinguishant, such as carbon dioxide, a fusible length of plastic tubing, such as one-half-inch-outside-diameter polyethylene tubing, with the end closed, and a conduit and valve system for connecting the extinguishant source to the fusible tubing. The valving system pressurizes the fusible tubing at a low pressure, and this low-pressure signal is coupled to a pilot input port in the valve system. When this low-pressure pilot signal is interrupted, the piloted valve switches to supply extinguishant at full pressure through the fusible tubing. If the fusible tubing has been melted, such as by a fire, the extinguishant exits through the melted portion to extinguish the fire. The low-pressure pilot signal can, however, be interrupted manually by the valve system. In this case, the full-pressure extinguishant supply to the fusible tube ruptures the tube and releases extinguishant. This provides a manual extinguishant control for the system.

The grid assembly includes protective elements having sufficient resistance to prevent the conveyed base from contacting the discharge element and to cast a persistent electrical shadow on the conveyed base. The protective elements are skewed longitudinally of the discharge element and relative to the direction of the conveyed base whereby the electrical shadow cast by the protective element is equally distributed over the conveyed base.

    Abstract: An electrostatic powder spraying apparatus that includes a nonrotating disk-like member having an edge; the electrostatic field extends between the edge of disk and articles to be coated. A first means of the apparatus deflects powder radially outwardly into a chamber. The chamber is adjacent the first means and provides space in which tangential streams impart a spiral motion or whirling cyclone-type motion to the radially deflected powder. An apertured means is spaced from the non-rotating disk-like member. The spiral motion of entrained powder moves it outwardly along the surface of the non-rotating disk-like member and causes air to be aspirated through the aperture to mix with the powder moving radially outwardly along the surface of the disk-like member. By this means the powder is given sufficient momentum to be ejected from the edge of the disk to the vicinity of an article at a powder attracting potential where the electrostatic field forces can guide the charged powder to the article.

    Abstract: A method of electrostatic spray coating an article includes the steps of establishing an electrostatic field having an average gradient less than 10 kilovolts per centimeter between a mist generator and the article to be coated; and maintaining a quiescent zone in the atmosphere adjacent the article to be coated, the distance of the article from the output of the mist generator being sufficient to permit substantial dispersion of the spray particles. Particles of less than 10 microns in size are continuously generated and they are accelerated under the influence of the electrostatic field for deposit on the surface to be coated. The electrostatic field carries the particles through the quiescent atmosphere so that a substantial portion of the mist particles which would not otherwise have been deposited on the article and liquid are deposited on the article. Relative movement between the mist generator and the article surface transverse to the general direction of mist particle movement during particle deposition is continuous.
