The invention relates to a withdrawal system (1) for filling and emptying containers and involves a container closure (2) that is inserted into a container opening of a container seating a bung head. An immersion pipe (4) connected to the bung head has an extraction connector element connected to the immersion pipe (4) or the bung head. A transponder generating a transponder signal is provided; a monitoring signal is generated in dependence upon the transponder signal that indicates whether there is a permissible connection of the extraction connector element to the container.

A fluid access and control system for controlling access to a fluid storage tank includes a pump, a valve, a communications device, and controller. The pump is configured to supply a fluid output from the fluid storage tank. The valve is configured to control the fluid output of the pump. The communications device is configured to communicate with both a portable electronic device and a remote server. The communications device receives an access request from the portable electric device and transmits the access request to the remote server for validation. The controller is configured to control the operation of the pump and valve as defined by control signals transmitted by the remote server and received by the communications device. The controller is further configured to activate the pump and open the valve when the access request has been validated by the remote server and a START switch is actuated.

A fuel dispenser comprises fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle. A plurality of fuel handling components are disposed along the fuel flow piping. Control electronics are in operative communication with the fluid handling components. A payment system includes a PIN pad that transmits secure tokens which are preferably cryptographically unique and independent such as not to be a function or derivative of network keys or user PIN. The tokens are then received and acted upon by a second subsystem to render PIN entry display data.

A fuel transfer pump electrical circuit for controlling a fuel transfer pump comprises a controller with communications logic configured for establishing a wireless communications link with a mobile device and a switch for activating a motor in the pump. The switch is controllably linked to the controller. The controller is configured to turn the switch on and off based on instructions received via the wireless communications link, thereby controlling the fuel transfer pump to turn a flow of fuel on and off. A mobile device application for interacting with the fuel transfer pump is also described.

In general, intelligent fuel dispensers are provided. In at least some implementations, an intelligent fuel dispenser can determine customer identities and/or other characteristics and provide customized fueling sessions based on the determined customer identities and/or other characteristics. In at least some implementations, the fuel dispenser includes a touchless interface allowing customers to complete fueling sessions with minimal physical contact with the fuel dispenser.

A tap group comprising a tap body provided with at least one dispensing exit, an operating lever or knob, a regulation member of the parameters of the flow of water to be dispensed (the parameters including the temperature and/or the flow of water and/or the direction of the flow), and a transmission including gears which operatively connect the operating lever or knob to said regulation member of the flow of water. Advantageously, the gears create a gear ratio between the operating lever or knob and a control rod of the regulation member of the parameters of the flow of water, so as to reduce the rotation of the control rod of the regulation member for the same rotation of the operating lever or knob. The tap group also includes a ring-nut provided with at least one indicator and/or a reference index of the parameters of the flow to be dispensed.

A quantitative essential oil dripping device which includes: N sealed essential oil containers for containing essential oil, wherein N is a positive integer greater than or equal to 1; N gas inlet tubes and N oil outlet tubes, which are all inserted into the N essential oil containers respectively, wherein in each of the essential oil containers, a gas outlet of the gas inlet tube is located above an inlet of the oil outlet tube; a gas pump arranged at gas inlets of the N gas inlet tubes; a throttle valve communicating the gas pump with the essential oil container; and a drip number detection module configured to detect the drip number of the essential oil dripped from an oil outlet of the oil outlet tube. During use, the gas pump is started, pressure is applied to the essential oil container through the gas pump, and the essential oil is driven to be dripped from the oil outlet tube under the combined action of the gas pump and the throttle valve, thereby achieving the dripping of the essential oil. The drip number of the essential oil dripped from the oil outlet of the oil outlet tube is detected through the drip number detection module, and the amount of the dripped essential oil is measured by recording the drip number, thereby accurately controlling the dripping of the essential oil. After the dripping of the essential oil is completed, the gas pump is stopped.

A fluid dispenser comprising a body (1), a fluid reservoir (2), a dispenser member, such as a pump or a valve, mounted on said reservoir (2), and a dose indicator device for indicating the number of doses of fluid that have been dispensed or that remain to be dispensed from said reservoir, the dispenser being characterized in that said dose indicator device includes a first safety system for actuating the dose indicator device once the dispenser has performed a predetermined incomplete actuation stroke, even if the dispenser does not perform the complete actuation stroke.
