Abstract: A disconnect apparatus for a gravity fed hopper for a paint spray pump includes a valve that automatically opens when the hopper outlet is attached to an inlet of the pump and closes when the hopper outlet is detached from the pump inlet. A structure for wiping the interior of the outlet may be provided to remove material from the outlet as the hopper is separated from the pump.

Abstract: A sealable funnel assembly is disclosed which comprises a funnel body with a stem portion and cup portion, the stem portion having a hollow bore formed therethrough. A core member is coaxially disposed within the funnel body and includes an upper handle portion and an enlarged lower sealing portion which fits sealingly inside the bore to temporarily prevent fluid flow through the funnel assembly. Motion of the handle portion of the core member upwardly or downwardly serves to either seal off the funnel assembly from fluid flow therethrough or to allow fluid flow through funnel assembly. The cup portion may have indicia inscribed thereon to aid in using the apparatus as a measuring device.

Abstract: The spill resistant bubble machine is an invention that because of its unique geometry and design, prevents spillage of liquid when filled to the fill line or below, and oriented in any position. At the same time the invention is capable of automatic and continuous bubble generation. It is principally intended for use by young children in the hands free automatic generation of bubbles, especially while riding a bicycle, without spilling its liquid contents.
