Abstract: The Condiment Sprinkler is a spoon- or spatula-shaped device which provides a way for dry salt-type condiments to be evenly and effectively sprinkled onto food (in contrast to the “shaker” method). The Condiment Sprinkler comprises a generally convex bowl or open-ended shovel-shaped spoon and a handle, the shallow bowl (which may be round, ovate, or elongated) being somewhat flattened on the bottom and having raised ribs therein. The raised ribs may form a cross design. The raised ribs—whether they be in a cross design or some other appropriate design, such as ribs or bumps—serve to interfere with or dampen the centripetal and/or centrifugal forces generated when the sprinkler is waved, thereby impeding dumping or clumping of the salt-type condiment on the food. With use of the Condiment Sprinkler, the user can gain precise control over the salt-type material he/she is applying.

Abstract: A spray gun has a fluid reservoir that contains a removable liner. The liner, which may be thermo/vacuum-formed from a plastics material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir has a removable lid and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid also functions to secure the liner in the reservoir and, at the end of a spraying operation, the lid and the liner are removed together from the reservoir and discarded, thereby simplifying the cleaning of the spray gun.

Abstract: An adjustable adapter includes two arms, each having an axis, a surface substantially normal to the axis, wherein the surfaces of the arms face each other, an end and a passageway for fluid communication between the end and the opening, wherein one of the arm ends is for connection to an inlet of an applicator and the other arm end is for connection to an outlet of a container, and a fastener for pivotally coupling the arms. One of the arm surfaces is provided with a groove in fluid communication with both arm openings. The groove is sealed to prevent fluid from leaking from between the surfaces. When the fastener is in a rotation-resisting mode, the fastener forces the surfaces of the arm toward one another sufficiently to increase friction and resist rotation therebetween, and when the fastener is in a rotation-permitting mode, the fastener releases the surfaces sufficiently to decrease friction and permit rotation therebetween.

Abstract: An apparatus for spraying plant-protective agents comprises a spray head having a motor, a spray plate mounted on the driving shaft of the former and a first container which is fastened to a lance. The container is connected via a connecting pipe line with a nozzle in the vicinity of the center of the spray plate.

Abstract: An airbrush of the double action type has an elongated unitary body having an axial passage for longitudinal movement of a needle supported therein. The rear end of the needle is carried by a guide slidably supported in the axial passage and normally urged by a spring in a direction such that the tapered front of the needle enters and closes the jet. A finger-operated lever formed of plastic and shaped to provide a "living hinge" is supported in the body and arranged to engage the guide and move the needle against the action of the spring to control paint flow, and at the same time to open a valve to allow entry of compressed air or other substance under pressure. The maximum paint flow at the fully-operated position of the control lever is predetermined by adjusting the longitudinal position on the body of a closure cap which limits the movement of the guide. The airbrush has a minimum number of easily assembled parts and features a relatively simple paint-to-air seal disposed within the axial passageway.
