Abstract: A hand-operated liquid spray apparatus operates on the air-lift pump principle wherein the air-forcing member and the spray-forming member are one and the same. Such an apparatus requires no nozzles or valves and no permanent pressurization of the sprayed liquid. A plurality of deflectable vanes are movably disposed in an open-ended chamber which communicates with the interior of a liquid container via separate air and liquid passages. The vanes, when at rest, seal both passages from the open chamber end. Operator-initiated motion of the vanes toward the air passage forces air trapped in the chamber through the air passage and into the container, thereby forcing liquid up through the liquid passage to wet the vanes in the chamber. A lip at the open end of the chamber is arranged to deflect the wetted vanes as they move past the lip. After passing the lip the deflected vanes spring back to their undeflected positions and, in so doing, throw off a spray pattern of liquid droplets.

Abstract: Steady flow of dry toner from the discharge outlet of a toner tank is produced by inducing vortex-like motion of toner within the tank to inhibit toner bridging. A rotating brush associated with the discharge outlet has a rim in grazing contact with an edge of a fixed, inclined plate to establish the toner motion. In a preferred form of toner-supplying device, two discharge outlets are used, each associated with a brush/plate set.
