A pneumatic liquid dispenser includes a container and a lid. When the lid is mounted on the container, the container supports passaging defining a gas supply inlet for receiving pressurized gas, a gas outlet for delivering pressurized gas to the container, and a gas flow path between the inlet and the outlet. A pressure valve is located between the gas supply inlet and the gas outlet. The pressure valve is configured to automatically permit gas flow along the gas flow path when pressure in the interior of the container is less than a threshold pressure and to automatically block gas flow along the gas flow path when pressure in the interior of the container is greater than the threshold pressure. When gas flows freely through the gas flow path, the gas pressurizes the container to dispense liquid in the container through a liquid passage.

A liquid dispenser includes a container and a lid. When the lid is mounted on the container, the container supports passaging including a gas supply inlet and a venturi. A control valve in fluid communication with the passaging is adjustable to a dispensing configuration and an evacuation configuration and a separate mode selector valve is adjustable to a dispensing configuration and an evacuation configuration. The dispenser dispenses liquid when both valves are in the dispensing configuration and evacuates liquid when both valves are in the evacuation configuration. The mode selector valve can block flow through a pressurization passage of the passaging in the evacuation configuration and through the venturi or other evacuation passage in the dispensing configuration.

In one embodiment, a dual modulator display systems and methods for rendering target image data upon the dual modulator display system are disclosed where the display system receives target image data, possible HDR image data and first calculates display control signals and then calculates backlight control signals from the display control signals. This order of calculating display signals and then backlight control signals later as a function of the display systems may tend to reduce clipping artifacts. In other embodiments, it is possible to split the input target HDR image data into a base layer and a detail layer, wherein the base layer is the low spatial resolution image data that may be utilized as for backlight illumination data. The detail layer is higher spatial resolution image data that may be utilized for display control data.

Devices, systems and methods of transferring liquids or mixtures/slurries of liquids and solids between vessels having challenging and difficult configurations and locations, and over long and short distances in a continuous or near continuous discharge for storage or transport using a combination of vacuum and pressurized fluids.

The present invention provides a dispensing system comprising a self-gassing liquid to be dispensed and a dispenser for dispensing the self-gassing liquid, the dispenser including: a valve housing having an inlet for receiving the liquid and an outlet through which the liquid is to be dispensed; a valve chamber and/or passage extending between the inlet and the outlet, and a valve arranged to open and close the valve chamber and/or passage; pressure maintaining means arranged to maintain the pressure of liquid at the inlet to the valve housing at a constant pressure during successive dispensing operations; and control means for controlling the opening and closing of the valve, the control means being arranged to open and close the valve to commence and terminate each successive dispensing operation, wherein the period for which the valve is open determines the quantity of liquid dispensed. The dispensing system may permit very small quantities of liquid to be dispensed with great accuracy and avoid the liquid being subjected to high shear forces. The system is particularly beneficial for the dispensing of peracetic acid.

A container for self-gassing liquids, the container comprising a receptacle and an insert arranged to seat within a neck of the receptacle, the insert being further arranged to engage and seal directly or indirectly with a connector extending across the neck of the receptacle. The insert defines a void defined by a base portion of the insert and a peripheral side wall of the insert extending within the neck of the receptacle, the insert comprising a hole in the base portion. The container further comprises a dip tube extending from a lower surface of the base portion to, or towards, the bottom of the receptacle. The dip tube defines a passageway through the base portion, or is connected and sealed to the lower side of a passageway through the insert, the passageway terminating in said void such that the hole and the passageway are in fluid communication with each other through the void. Self-gassing liquids may be safely stored and transported in the container without risk of over-pressurisation of the internal volume of the container, which may also be quickly and easily installed into a dispensing device by the end user, requiring minimal handling by the user.

A liquid transfer apparatus and a control method thereof are provided. The liquid transfer apparatus includes a first auxiliary cover, a second auxiliary cover, a transfer tube and a breathing pipe. The first auxiliary cover is configured to cover a container for holding a liquid to be transferred; and the second auxiliary cover is configured to cover a target container. One end of the transfer tube runs through the first auxiliary cover and the other end runs through the second auxiliary cover. One end of the breathing pipe runs through the first auxiliary cover and the other end is configured to introduce nitrogen, or an inert gas, so that the liquid in the container for holding the liquid to be transferred can be transferred to the target container through the transfer tube.

The present invention relates to automated batch making assemblies where various component materials, at least, some in liquid form, are combined. Specifically, the invention provides a dispensing assembly that adds efficiency by increasing dramatically the speed with which a liquid is dispensed from a container and by providing means and methods to automate the addition of and account for the amount of each component.
