Abstract: An apparatus for preparing dialysate concentrate includes a vessel, a controllable valve for regulating water flow to the vessel, a first sensing device for detecting when the liquid has reached a lower level, a second sensing device for detecting when the liquid has reached an upper level, a controller selectively responsive to one of the sensing devices, and a positionable switch for selecting to which of the sensing devices the controller is responsive.

Abstract: A method and apparatus for preparing baby milk by reconstituting the contents of a pack of dry baby milk product in a mixing vessel is disclosed. The method includes the steps of adding water into the vessel until the liquid level reaches a liquid level indicator, adding the contents of the pack into the vessel and screwing a liquid tight lid onto the vessel and agitating the contents thereby reconstituting a volume of baby milk sufficient to make up two or more feeds for infants aged 0 to 24 months.

Abstract: A device for mixing at least two liquids has a first container for metering the volume of a first liquid and a second container larger than the first container, wherein the first container is arranged in the second container. The second container is fillable with the first liquid and a second liquid.

Abstract: This invention provides a system and a method of mixing and dispensing a beverage from a beverage concentrate. A mixing device receives a beverage concentrate and water, and employs a static mixing device to mix the concentrate and water to produce a beverage in a closed system. Flow regulators precisely control the flows of the beverage concentrate and water to achieve the desired mixing ratio. The carbonation system may include a pump for pumping the beverage from the mixing device to a carbonator, a refrigeration unit, a beverage dispenser, or other. A transformer is coupled with the pump and one or more solenoid valves in the mixing device. The transformer receives power from the pump motor to activate the solenoid valves to allow flow of the beverage out of the mixing device only when the pump is powered. When the pump is shut off, the power to the transformer is terminated and the solenoid valves are switched off to stop the flow of the beverage out of the mixing device.

Abstract: A blender for delivery of blend additives to a plastics extrusion device has a mixing chamber for reception of materials to be blended. Batches of blend materials are delivered to the mixing chamber from material supply bins via a weight hopper. Within the mixing chamber, a mixing screw circulates and mixes the blend materials prior to discharge through an outlet to an extrusion process line. As material is discharged, a material level sensor is uncovered and calls for a further batch of blend materials to be discharged from the weigh hopper into the mixing chamber. The screw has a pair of mixing blades of opposed pitch to direct material inwardly from outer ends of the screw towards a center of the screw located above the outlet. Excess material above process demand requirements is delivered to the outlet by the screw. This excess material is directed upwardly away from the outlet and recirculated towards outer ends of the screw and remixed without material within the mixing chamber.
