A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

Systems and methods of custom condiment dispensing include a reservoir of base condiment and a plurality of flavoring reservoirs. A first pump is pneumatically connected to the reservoir of base condiment. The second pump is pneumatically connected to at least one flavoring reservoir of the plurality of flavoring reservoirs. A nozzle is fluidly connected to the reservoir of base condiment and fluidly connected to the plurality of flavoring reservoirs. The nozzle is configured to simultaneously dispense the base condiment and at least one flavoring therethrough. A controller receives the user selections of the base condiment and the at least one flavoring and operates the first pump and the second pump to dispense base condiment and at least one flavoring.

A method of delivering a selected fuel product having a selected octane level to an operator from a fuel dispenser including a blend manifold, a fuel nozzle, and a fuel hose extending therebetween, including the steps of determining a first volume of a first fuel that is retained in the fuel hose upon completion of a first fueling event, determining a first octane level of the first volume of the first fuel, determining a second volume of a second fuel having a second octane level, and delivering the first fuel volume and the second fuel volume to the operator during a second fueling event, wherein a total volume of fuel equaling the first volume of the first fuel and the second volume of the second fuel has a total octane level that falls within a predetermined limit of the selected octane level of the selected fuel product.

Systems and methods are disclosed to mix a base ingredient, such as water, with an additive, such as a cleaning concentrate. A dispensing system of the disclosure can include a container filling apparatus. The container filling apparatus can include one or more source containers that contain an additive to be mixed with water or other base ingredient. The container filling apparatus can include a vacuum manifold and a Venturi body assembly (VBA). The additive can be flowed through the vacuum manifold and into the VBA. In the VBA, the additive can be mixed with water or other base ingredient, and output to a receiving container. As the additive is flowed through the vacuum manifold, vacuum pressure in the pressure manifold can be measured by a pressure sensor. A controller can input pressure data from the pressure sensor over the course of a dispense event. Over the course of a dispense event, flow of additive can be varied or modulated based on the pressure data. The flow of additive can be provided, as controlled by the controller, in a sequence of pulses. The length of a pulse, in a dispense event, can be adjusted based on observed pressure data in prior pulses.

A retail fueling station includes: (a) a fuel supply line extending between a fuel storage tank and a fuel dispensing system; (b) a treatment fluid supply line coupled to a treatment fluid storage tank; and (c) a treatment fluid injection system including: (i) a mixing conduit mounted to the fuel supply line and through which untreated fuel flows when conducted through the fuel supply line from the fuel storage tank toward the fuel dispensing system; (ii) one or more pressure reducers in the mixing conduit for providing a reduced pressure region immediately downstream of each pressure reducer; and (iii) one or more injection ports in the mixing conduit for injection of treatment fluid received from the treatment fluid supply line into corresponding reduced pressure regions for mixture with the untreated fuel flowing through the mixing conduit to produce treated fuel.

The disclosure relates to methods for distributing alcohol-containing gasoline. The methods herein facilitate the combination of gasoline blendstocks and alcohols to create finished gasoline products. The methods herein also measure the volumes and other characteristics of the gasoline blendstocks and alcohols and employ computers and controllers that calculate the gross and net volumes of liquids, including the net volume of finished gasoline products.
