An end of the retaining wire opposite the stem is secured to a component for executing the motion of the impact body relative to the atomizer plate such that an orifice opening at the surface of the atomizer plate between the atomizer plate and impact body can be closed via the retaining wire and the stem of the impact body.

Abstract: A hydraulically actuated device is employed as part of a pool cleaning system. An improved structure assembly of a hydraulically actuated core within a housing provides ease of manufacture and assembly. Graded control of the application of pressure and the flow of fluid through the system is provided so that the hydraulic device is actuated in a relatively gradual and graded manner to overcome the deleterious effects of abrupt actuation of such devices and the resultant water hammer, pressure surges which are generated in such abruptly operated systems. Improved jet orifices enclosed within the hydraulically actuated cylinder of the device provide for more efficient disturbance of sediments on the interior surfaces of the pool in the immediate vicinities of the hydraulically actuated devices.

Abstract: A single-point fuel injection system including an electromagnetically-operable ball valve injector. The injector comprises a hollow body which is surrounded by an annular gallery through which fuel is circulated under pressure continuously. Inlet ports are formed in the body whereby fuel from the gallery enters a chamber within the body in a direction transverse to the axis of the injector. The chamber communicates with the nozzle orifice via an aperture within which the ball valve is located. The difference between the diameter of the aperture and the diameter of the ball is sufficiently small to restrict fuel flow from the chamber to the nozzle orifice so that the valve is urged to seat and close the nozzle orifice by the differential fluid pressure loading on it.

Abstract: An electrostatic spray coating device in which a coating material passes through a tube in a body and is electrostatically charged by electrodes as it exits the body. In the body is mounted a bar transformer for providing a high voltage to the electrodes. A magnetic conductor bar, such as a ferrite core, is also mounted in the body outside the bar transformer for conducting magnetic flux between its ends, thus providing a flux circuit within the body. If more than one conductor bar is used, the bars are spaced to facilitate heat discharge. A multiplying and rectifying circuit such as a Greinacher circuit may also be mounted in the body between the transformer and the electrodes, with its components distributed around the tube.

Abstract: A liquid spray nozzle especially designed to spray vaporizable liquid fire extinguishant onto an explosive fireball. A minor portion of the incoming liquid is used to develop transversely directed liquid pulses which act on the liquid mainstream to deflect the stream from one nozzle boundary wall to another boundary wall. The exit stream from the nozzle exhibits a transversely oscillating character for minimizing vacant spots in the spray pattern while achieving a relatively divergent spray cross section. The method of oscillating the mainstream uses a relatively small energy expenditure so that the mainstream has a relatively long spray penetration distance.

Abstract: The present invention relates to a rotary spreader where material is deposited on a rotary disc and is broadcast upon rotation of the disc as the spreader is moved. The present invention is directed to a jet action deflector which is used with the rotatable disc. The jet action deflector functions to intercept the material which is broadcast by the rotatable disc, which material would normally be directed to one side of the spreader, and redirect that material across the front of the spreader and to the other side of the spreader. The intercepted material is effectively shot at high velocity by the jet action deflector across the front of the spreader to the opposite side of the spreader. As a result, this material is spread over a wide area of the turf and is not concentrated in any particular area. The deflector may be used to prevent spreading of material on a driveway or sidewalk when the rotary spreader is being used adjacent the driveway or sidewalk.
