Abstract: The projecting nozzle for powder coating is a device for dispersing finely divided powder paint particles in a pattern controlled by swirling air without accumulating unwanted powder particles. A hollow nozzle is located concentrically to a guide member forming a gap through which the powder is projected. Orifices and, or slits located in the guide member direct compressed air in a swirling motion. A porous plate, forming the front of the guide member allows air to pass therethrough and thereby prevents the accumulation of powder particles.

Abstract: A carrier for inflatable pneumatic tires is supported for tilting travel about a substantially vertical axis upon an arcuately spherical universal pivot resting upon a seat having a corresponding sphericity. The seat surmounts a pedestal, and the pedestal and carrier are jointly formed with an air conducting means, the continuity of which is interruptible, to admit air to and from a tire mounted for balancing upon the carrier, to inflate and deflate such tire. The pedestal surmounts a fluid motor provided with two pistons in tandem: one piston carries an actuating rod to operate a valve to admit air to a tire prior to balancing, and to resist escape of air from an inflated tire on the carrier during balancing. The carrier is equipped with a lower rim element to engage a lower bead of a tire and an upper rim element to engage an upper bead of a tire. The upper rim element is removable.
