摘要:
The present invention discloses a liquid volumetric device comprising a metering tube, a start sensor, an end sensor, a bath for storage of a sample to be metered, a vacuum chamber and a pump for pumping out air inside the vacuum chamber to form a negative pressure inside the vacuum chamber. The start sensor and the end sensor are provided respectively at the bottom and the top of the metering tube, the top of the metering tube is in communication respectively with the vacuum chamber and the outside atmosphere via pipelines, the bottom of the metering tube is in communication respectively with the bath and the vacuum chamber via pipelines, and control parts are provided in each of the pipelines for controlling connection/disconnection thereof. Thus, by forming a negative pressure inside the vacuum chamber, a sample in the bath may be pressed from down to up into the metering tube by means of a pressure difference between the atmosphere and the negative pressure, so as to complete the volume metering, whereby an occurrence of the side flow phenomenon can be completely eliminated.

A toggling dispenser is disclosed with a reservoir capable of containing substances and an integrally placed applicator which, at the user's election, enters and exits the dispenser by shifting or shaking the dispenser. While inside the dispenser, an amount of contained substance collects on the applicator so that when the applicator exits the enclosure, the collected substance may be delivered to a target via contact with the applicator.

A dispenser of washing agents for a dishwasher has a body with a reservoir configured for containing a total amount of a liquid substance sufficient for performing a number of cycles of operation of the dishwasher. The reservoir has a charging passage that can be engaged by a removable plug, and the dispenser has a system for dosage of the liquid substance contained in the reservoir. The plug is configured for co-operating with an adjustment element belonging to the dosage system when the plug itself is at least partially inserted in the charging passage, particularly in such a way that a movement of rotation manually imparted on the plug will bring about a movement of rotation of the adjustment element.

A toothpaste dispensing toothbrush is provided that includes a main body that contains a bladder therein that serves to contain a volume of toothpaste. A metered dosing pump is included that controls the flow of toothpaste from the fluid storage region and through a conduit that exits adjacent the bristles of the toothbrush head. Each operation of the metered dosing pump dispenses a measured and controlled amount of toothpaste into the bristles of the toothbrush. In addition to providing a flow of toothpaste, the rear side of the toothbrush may also include an additional “flavor burst” pack module to deliver an additional flavoring or another material, such as fluoride, to the flow of toothpaste.

An apparatus releases a sunless tanning product from one or more containers for uniform spray application to the skin of the user. In a preferred embodiment, the apparatus is structured as a vertical tower and a plurality of containers are held in spaced vertical alignment so that each container is positioned in operative alignment below an actuator lever. A control knob is operatively linked to the actuator levers, whereupon operation of the control knob serves to move the actuator levers to simultaneously depress discharge nozzles on each of the containers, thereby causing sprayed release of the sunless tanning product with the assistance of a propellant, such as aerosol. In the preferred embodiment, the control knob is connected to a cam mechanism which, upon rotation thereof, serves to move a linkage to operate the levers relative to the discharge nozzles of the containers between an off position and an on position. The tower is surrounded by a housing having vertically arranged nozzle openings aligned with the nozzles of the spray containers. The control knob is accessible on the exterior of the housing. In another embodiment, the apparatus holds a single container of the sunless tanning product for spray application to the face.
摘要:
A fuel dispensing installation that includes first and second fuel tanks containing first and second fuels of different octane levels. The tanks are provided with first and second octane level sensors mounted in the first and second fuel tanks respectively for measuring fuel octane levels and generating output signals indicative of the octane levels of the first and second fuels. Conduits from the first and second tanks transport the fuel to one or more fuel dispensers. The fuel dispensers include a blending system for blending the first and second fuels to form at least one blended fuel having an intermediate octane. A site controller in electronic communication with the blending system receives the output signals and controls the blending system to permit the dispensing of one or more blended fuels based on the measured octane levels of the first and second fuels.
摘要:
A vapor recovery system (20) with integrated monitoring unit (28). The system includes one or more tanks (22, 24, 26) into which captured vapor is returned. A pressure sensor (52) is mounted into each tank not in fluid communication with the other tanks. The signals produced by the pressure sensors are forwarded to a control module (54). In the event the measured pressure drops below a selected level the control module actuates an alarm (56). The control module also disables the dispenser (31, 32) generating the liquid that is being vaporized.
摘要:
A pumping and metering dual piston system for simultaneously injecting controlled amounts of sample and reactants into a reaction chamber and an enzyme into an adjacent injection chamber. A rotary shaft is actuated to communicate the injection chamber with the reaction chamber and to actuate a mechanism for forcing the enzyme from the injection chamber to the reaction chamber. Additionally, the shaft supports and operatively rotates detector apparatus from a magnetic and light radiation shielded position to a position for monitoring the reaction chamber constituents.
摘要:
Liquid dosage dispensing apparatus, characterized by the combination of means for pumping a selected quantity of liquid from constant liquid level container means to a discharge nozzle, and nozzle positioning means for displacing the nozzle from an initial storage position in which the nozzle is partially submerged in the container liquid to a dispensing position relative to a liquid receiver. The dosage pump means include reciprocatory piston means alternately operable to draw, by suction, a desired volume of liquid into a chamber and to discharge this desired volume from the chamber. Slide valve means are provided that tee operable in synchronism with the piston to connect the chamber alternately with the container and with the nozzle means, respectively.
