Abstract: A volumetric flow measuring and metering device for flowable solids as a flow passage through which a flow of bulk material may be passed. An obturating device is positioned at the bottom end of the flow passage and is movable in a linear direction toward and away from the bottom end. The obturating device is positioned relative to the bottom end of the flow passage at a distance that imparts a consolidated, column-like flow of the bulk material in the flow passage. A speed sensor operates to measure a speed of consolidated, column-like flow of the bulk material in the flow passage. A controller uses the speed data from the speed sensor to calculate a volumetric flow rate of the bulk material flowing through the flow passage. The obturating device can be selectively positioned to increase or decrease the volumetric flow rate of the bulk material. Other aspects are also provided.

Abstract: A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed.

Abstract: The invention relates to a device for metering carbon dioxide snow, comprising a storage container and a discharge opening arranged in the base of the storage container. A horizontally and vertically movable base, by means of which the discharge opening can be opened and closed, is arranged in the region of the discharge opening. A horizontally movable cutting knife is vertically spaced from the base and can be moved into the interior of the storage container. Once the storage container is filled with carbon dioxide snow a metered amount of carbon dioxide snow present between the cutting knife and the base is cut off by the cutting knife and compacted by vertical movements of the base and is then discharged by the base moving into the open position.

Abstract: A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

Abstract: Multiple food ingredient dispensing device that include a body having a dispensing opening and an internal orifice plate that supports a release mechanism. The device either includes a carousel unit on a central axle or a carrier that turns on a bearing. The carousel unit or carrier hold a plurality of ingredient pods that contain food ingredients, and which rotate relative to the body. Rotating the ingredient pods can cause a selected one to rotate over the release mechanism. The release mechanism can then cause a controlled volume of the food ingredient to fall from associated ingredient pod. Also included are a viewing window with measurement indicia and a measurement adjust knob that adjusts the amount that falls when the release mechanism is opened. A dispensing opening then allows the food ingredient to fall out of the dispensing device.
