  • Patent number: 7147012
    Abstract: A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale linked to a controller. The controller is linked to a plurality of two stage valves which control the dispensing of large quantities of base materials. The controller is also linked to a plurality of nutating pumps which together with the controller controls the dispensing of smaller quantities of additive materials. The dispensing system disclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added by weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smaller amounts of additives by volume using the nutating pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus.

  • Patent number: 6935386
    Abstract: An improved cosmetics dispensing system that includes a controller, a plurality of mutating pumps, a plurality of reservoirs of cosmetics ingredients, a plurality of nozzles, a manifold for concentrically supporting the nozzles, a turntable rotatably connected beneath the manifold wherein the turntable includes a through opening for permitting the passage of fluid from one of the nozzles through the turntable, a motor for rotating the turntable, and wherein the controller is linked to each of the mutating pumps and the motor and each pump is in fluid communication with one of the reservoirs and vice versa and each pump is connected to one of the nozzles and vice versa. The system is computer operated whereby the turntable can rotate in either of the clockwise or counterclockwise directions and the turntable is equipped with a container holder that can accommodate containers of varying sizes.
