Abstract: An oil dispensing device is provided with a funnel and with a cradle located at the funnel mouth for releasable, rotatable interengagement therewith. The cradle has a chute with an upwardly directed piercing blade at its lower extremity and a trigger mechanism for forcing an oil can down onto the piercing blade at its upper extremity. Rotation limiting stops on the cradle and funnel prevent the chute from being rotated upward beyond the edge of the mouth of the funnel.

Abstract: The apparatus comprises a housing having individual compartments for separately storing an epoxy resin material and a reactive hardener for the epoxy resin, a rotatably adjustable housing having a first and second stationary position, an aperture for each compartment disposed in the first position above the level of each material and disposed in the second position below the level of each material and a syringe for each aperture for extracting and dispensing a predetermined measure of each material.

Abstract: A low-cost, motor-less carbonator has a housing having a fill chamber and a carbonation chamber. The chambers are maintained at different pressure levels to create a fluid movement from the fill chamber to the carbonation chamber. The fill chamber can be vented to allow a low pressure water feed to refill the fill tank. Carbonated water from the carbonation chamber is withdrawn on demand by a dispensing means.

Abstract: In a copying machine, a container holds toner to be sprinkled on the selenium drum. Toner to replenish the amount consumed in making copies is directed from a supply vessel through a rotary slide valve into an inlet duct for the container. A container pocket for holding the toner supply vessel is mounted on and is rotatable with a part of the valve so that it can be located in an upper and a lower position. In the upper position the valve opens into the inlet duct, however, in the lower position the valve closes the opening into the duct and the supply vessel can be removed from the container pocket.
