Abstract: A pump suction tube support is mounted at the bottom of a fluid vessel such as a barrel for supporting the tube and providing stability to the pump which is mounted on the top of the barrel. The support includes a hollow cylindrical support member for receiving the suction tube and an enlarged base secured to the bottom wall of the vessel. The lower end of the support member has a series of spaced apart feet secured to the base member and the spaces between the feet provide communication for the fluid to flow into the bottom of the support member. The support member may include a diametrically extending slot for receiving a pin in the tube to prevent rotation of the tube.

Abstract: A non-carbonated beverage dispenser having an in-bowl whipper assembly which includes a housing disposed in the bowl and immersed in the beverage, a magnetically driven impeller in the housing, and a discharge passage from the housing connected to the spigot of the dispenser to discharge the whipped beverage from the bowl. The whipper is rotated at 4000 rpm or above, and the height of the impeller blades is made very small (in the order of 1/32 to 1/16 inch) to produce very fine and uniform bubbles in the beverage without uncoupling the magnetic drive.

Abstract: In a pressure-fill container filling machine a vertical dispensing cylinder contains a piston that is forced upwardly by liquid product entering an inlet-outlet port in the bottom of the cylinder, the piston being forced downwardly by air pressure to expel the product from the volume chamber beneath the piston. The side of the cylinder at the upper end of the volume chamber is provided with a normally closed bleed passage for air. A tubular member extending downwardly from the inlet-outlet port has a lateral outlet opening connected by a by-pass passage with an inlet to the volume chamber spaced laterally from the inlet-outlet port. A check valve in the by-pass passage permits flow of liquid product therethrough under pressure from the tubular member only toward the volume chamber for flushing air out through the bleed passage while the piston is held in its lowest position.

Abstract: The present invention is concerned with an atomizer usable in both normal and inverted orientations, in which only the liquid to be atomized is sucked up into a pressurizing chamber 7 of a pump mechanism, while completely avoiding the flow of air into the pressurizing chamber, in both the normal and inverted orientations. The sucking of only the liquid is achieved by use of a suction passage 15 for operation in the inverted orientation provided in an ordinary pump mechanism 2, the suction passage 15 being opened at its one end to the pressurizing chamber and at its other end to a space outside and above the pump mechanism, and a stop valve 13A disposed in the suction passage 15 and adapted to open when the vacuum in the pressurizing chamber has been increased beyond a predetermined level, in the operation in inverted orientation.

Abstract: A device for conveying and dispensing liquid media such as casting resin has at least one piston pump having a cylinder chamber which forms a seal for a piston therein which is connected via an input opening to a feed container for receiving a supply of liquid therefrom. The cylinder chamber has an output opening and the piston is tubular in form having wall perforations in the region of the input opening for admitting the liquid to the interior of the piston and has a valve at a discharging end thereof for exit of the liquid from the piston. A seal is thus formed by which the piston operates entirely surrounded by the liquid medium to be dispensed and external seals between the piston and the atmosphere are eliminated.

Abstract: A miniature type, invertible atomizing spray mechanism includes a receptacle for liquid to be atomized, and further includes at least one pressure chamber, which depends within the receptacle and is arranged to have received therein a piston with which a reciprocable spray head is arranged to cooperate. Beneath the pressure chamber is disposed a valve member which is adapted to control the suction of the liquid into the pressure chamber. The valve member opens an inlet of the pressure chamber by the reciprocal movement of the spray head. The inlet of the pressure chamber is in fluid communication with a passage leading to a three-way valve. The three-way valve includes upper and lower valving assembly which communicate with a passage extending to the cylinder of the atomizer, each of the valving assembly being in communication with the bottom of the receptacle as well as an area adjacent to the neck portion of the atomizer through elongated tubular elements.

Abstract: A liquid dispenser includes a nozzle and pump assembly mounted on a cap for a container. A straight suction tube below the cap leading from the nozzle and pump assembly to the bottom of the container is perforated just below the cap and an attachment which is a short length of tube is carried about the suction tube in a manner where it may be slid sealably over the perforations to permit fluid to be sucked from the bottom of the container. For dispensing or spraying liquid with the container upside down, the perforations are left uncovered, and the end of the tube at the bottom of the container is sealed with a removeable end cap attachment. To enable the last of the liquid in the container to be dispensed a removeable 90.degree. elbow attachment is provided fitted on the bottom end of the tube.
