Abstract: An outer tube 5 is integrally rotated with a rotating disk 17. A powder supply passage 16 for supply of powder particles is formed between an inner tube 15 and the outer tube 5. A lower end of the inner tube 15 is secured to a sub-disk 23, and a distributing passage 25 is formed as a space between the sub-disk 23 and the rotating disk 17. Air including powder particles introduced into a separation passage 41 is separated into air and powder in the separation passage 41, and the particles are fed to the distributing passage 25 through the powder supply passage 16. The powder particles falling in the powder supply passage 16 undergo a swirling motion in accordance with the rotation of the outer tube 5, and owing to the swirling motion, the powder particles in the powder supply passage 16 are distributed uniformly in the circumferential direction.

Abstract: A nozzle assembly (16), for spraying a liquid such as a urethane prepolymer on a substrate, has a liquid spray nozzle (28) with a center line (56). Air nozzles (30), with center lines (62) that are substantially parallel to the center line (56) of the liquid spray nozzle (28), are provided in the nozzle assembly (16) around the liquid spray nozzle. Air passing from the air nozzles (30) surrounds and encloses the liquid spray and decreases the size of the liquid spray fan pattern (58 or 70). The air spray nozzles (30) can be positioned in the nozzle assembly (16) to change the shape of the liquid spray fan pattern (58 or 70) as well as the size. Mixing of air and liquid is minimized by spraying air and liquid in parallel paths.

Abstract: A method and apparatus are provided for operating a small diameter thermal spray gun to thermal spray a coating onto a substrate. A fuel is burned within a combustion chamber of a small diameter thermal spray gun to generate a high energy flow stream, into which a coating material is injected. The combustion chamber includes an inner sleeve with cooling ports which pass cooling air laterally therethrough. A flow nozzle directs the high energy flow stream towards the substrate. The flow nozzle transfers a heat flow from a first portion of the high energy flow stream to a second portion of the high energy flow stream, and provides a thermal barrier to retain heat within the high energy flow stream. The small diameter thermal spray gun may be tuned for operating with a wide variety of coating materials by replacing the combustion chamber inner sleeve and the flow nozzle thermal transfer member with alternative members.

Abstract: The present invention relates to a spraying apparatus and a method of using the same. The spraying apparatus can be used in the spraying of herbicides or insecticides from an aircraft or from the ground. The apparatus provides a separation chamber to remove the small drop component of the spray so that the component leaving the apparatus is essentially free of small drops. Small drops have slight fallspeeds and are subject to wind drift, causing off-target deposits and potential biological impact outside the treatment areas.

Abstract: A rotary oscillating irrigation sprinkler head is supported in a stable elevated position above the ground surface, such that the sprinkler assembly can be used on a lawn or in garden foliage. A tripod support structure is connected at its upper end to a vertical water supply pipe that connects with the sprinkler head, so that the sprinkler head has a stabilized support above the ground surface. The water supply pipe delivers a pressurized stream of water to the sprinkler head.

Abstract: An improved multi-component mixing and dispensing apparatus having a replaceable nozzle associated therewith in which plural components are mixed before dispensing thereof. The apparatus includes improved component feed systems to maintain each component to be mixed and dispensed in a segregated condition until mixing is desired, such that the apparatus is especially suitable for the mixing and dispensing of chemically reactive components. The component feed systems include internal passages within the apparatus and is selectively actuated valve which is operable to allow flow of a component to an outlet port formed in the apparatus. A mixing and dispensing nozzle may be coupled into the apparatus so as to communicate with the outlet ports of the component feed systems, wherein improved mixing of the plural components is achieved within the nozzle assembly.

Abstract: The present invention is a nozzle gun assembly that is axially mounted toward the front of the water gun barrel of a conventional pump-action-type water gun. The nozzle assembly has a nozzle head with a control wheel section. The squirting of the water gun simultaneously causes the actuating member to act against the control wheel, thereby turning the nozzle head on its axis. In this manner, as water is pumped through the nozzle head and out the nozzle, the nozzle head is accordingly rotated so that the stream emitted from the water gun travels an angular path, eg. from left to right. The assembly also has means for disconnecting the actuating member from the control wheel so that the water gun can be utilized in a more conventional manner.

Abstract: There is provided an electrically conductive plastic tip guard for a hydraulic or airless spray gun adapted for the hydraulic atomization and spraying of fluid such as paint. The electrically conductive plastic tip guard when in contact with a grounded surface dissipates to ground the static electricity generated by the passage of the fluid through the spray tip.
