Patent number: 5893515Abstract: A device for generating a spray of mist or fine droplets includes a spinning rotor within a mist chamber. The rotor has inner walls which taper conically outwardly from the open bottom of the rotor to a hole near the top of the rotor. Liquid is pumped by a finger actuated pump from a cartridge module into a bowl surrounding the bottom end of the rotor. A spray is created as the liquid is formed into droplets as it passes through the hole in the rotor under centrifugal force. A directional light source is used for aiming the spray.Type: GrantFiled: April 1, 1994Date of Patent: April 13, 1999Assignee: Gary S. HahnInventors: Gary S. Hahn, David R. Williams

Patent number: 5752657Abstract: A rotating fluid wide band applicator head which permits application of a relatively wide band of fluid without the necessity for translational motion of the head with respect to the object being coated. The applicator head includes a rotatable body having an axis of rotation and having a fluid delivery chamber disposed within the body. A plurality of bounded channels having open inner ends and open outer ends are provided. The open inner ends of the channels are in fluid communication with the fluid delivery chamber, to receive fluid therefrom and transport the fluid. The open outer ends of the channels are arranged to discharge the fluid in a desired pattern, resulting in deposition of a band of fluid having a desired width.Type: GrantFiled: March 29, 1996Date of Patent: May 19, 1998Assignee: Loctite CorporationInventors: Michael B.

Patent number: 5647535Abstract: The present invention relates to an efficient method of applying a metallic paint using both an air atomized spray machine and a spin coating machine. In the method of painting, matching the color shade of metallic painting using an air atomized spray machine with the color shade of metallic painting using a spin coating machine is achieved in the following manner. The overall content of the metallic pigment in the metallic paint for said air atomized spray machine and for said spin coating machine is maintained almost the same, but the ratio of the brilliant pigment and the color pigment composing said metallic pigment is varied to increase the content of the brilliant pigment in the metallic paint for the spin coating machine compared with the content in the metallic paint for the air atomized spray machine.Type: GrantFiled: October 20, 1995Date of Patent: July 15, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Daisuke Nakazono, Shuji Monoura, Kazuo Nakagawa

Patent number: 5501396Abstract: A cyclonic power wash system uses high pressure, high temperature water for selectively cleaning large, flat, concrete or asphalt surfaces. The sprayed water is reclaimed by vacuuming it through holes in the bottom of a reclamation ring attached to the underside of the mobile cyclone sprayer, filtering the vacuumed water and returning it to a storage tank for re-use by the system. The filtration tank initially filters out large matter in an inlet trough and smaller matter in a plurality of cascading chambers. A rotary union in the sprayer prevents the water, passing from the inlet of the rotary union to the discharge thereof, from leaking through or around a seal formed by pressing together a pair of hard, durable sealing surfaces, for example, silicon carbide, one of which is non-rotatably slidingly received in an upper recess of the union's fixed housing and the other, affixed to a spindle rotatably received and retained in a lower recess of the housing.Type: GrantFiled: November 22, 1994Date of Patent: March 26, 1996Assignee: Cyclone Surface Cleaning, Inc.Inventors: Richard D. Rohrbacher, Judith M. Jacobson

Patent number: 5452853Abstract: A sprayer for applying an uncured grout to the interior surface of an enclosed wall includes a sprayer motor having a rotor rotatably mounted within the motor housing. A spray head is attached to the rotor and a spray conduit is adapted to introduce fluid grout under pressure to the spray head so that it will be thrown radially outwardly in a circular pattern. The motor and spray head are inserted into a conduit and actuated to throw the grout outwardly on to the interior walls of the elongated conduit.Type: GrantFiled: May 4, 1994Date of Patent: September 26, 1995Assignee: Action Products Marketing CorporationInventors: William E. Shook, Danny C. Jury, Carroll O. Trimble

Patent number: 5447272Abstract: A device for spreading a deicing agent onto any surface either autonomously, manually or by remote control. Upon detecting the onset of icing conditions, the device delivers either a granular or liquid deicing agent unto the targeted surface, preventing ice build up. The key components of the device include the deicing agent storage container ,the freezing sensor, the moisture detection sensor, timing circuits, power supply, motor, pump or impeller and switching system circuitry. The device also possesses the capability to log and or transmit data to a central site and can activate various warning signals. The device is contained within a corrosion, weather and vandal resistant housing and is powered by either line current with a battery backup or by battery power alone. The system is designed to require low maintenance and of rugged construction to endure harsh environmental exposure.Type: GrantFiled: February 22, 1994Date of Patent: September 5, 1995Inventor: Bernard J.

Patent number: 5275335Abstract: A spreader apparatus is disclosed for spreading manure. The apparatus includes a container which defines an opening for the reception therein of the manure. The container has a first and a second end zone with the first end zone defining an outlet for the discharge therethrough of the manure. A rotatable feed device is disposed within and co-operates with the container for feeding the manure through the container. The feed device has an axis of rotation which extends through the end zones of the container. A rotatable discharge device is disposed within the container and co-operates with the container and the feed device for moving the manure towards the outlet. The discharge device has a further axis of rotation which is disposed spaced and parallel to and laterally below the axis of rotation of the feed device. The arrangement is such that when the feed and discharge devices are rotating, all of the manure within the container is fed at a substantially constant rate towards the outlet.Type: GrantFiled: May 3, 1993Date of Patent: January 4, 1994Assignee: Knight Manufacturing Corp.Inventors: Stanley W. Knight, William M. Saunders, Ric S. Joranlien

Patent number: 5199638Abstract: A manure spreader device and method of distributing any of a variety of manure materials having varying consistencies are provided. The device and method embody a concept in which a plurality of elongated augers that are longitudinally positioned within a translatable bin deliver manure material to an outfeed location for translation of the manure material to a beater assembly which distributes the manure material onto a field or the like. A slippage characteristic is exhibited at the outfeed location whereby, when manure material within the outfeed location exceeds the expelling rate capacity of the beater assembly, slippage occurs between the manure material and rotating blades at the outfeed location so as to avoid overloading of the beater assembly by the particular manure material being spread.Type: GrantFiled: March 23, 1992Date of Patent: April 6, 1993Assignee: Allied Products CorporationInventor: Thomas R.
