Abstract: A plant cultivation apparatus includes a water resistant sheet of material, with at least one opening formed in the sheet to enable growth of a plant through the opening. A fertilizer band, which can be contained within a membrane, is affixed to an underside of the sheet and includes a predetermined amount of a plant nutrient. The inventive apparatus is placed on top of a growing medium. With the fertilizer band in contact with the growing medium, a nutrient gradient is established so that plants growing through the openings formed in the sheet receive nutrition.

Abstract: A product supply management system provides the capability to regulate the delivery of a product into a containment device. The containment device may be part of a product dispenser, such that the product dispenser regulates the delivery of product from a product generator. In a first embodiment, the product level determiners are disposed at varying levels of the containment device, and are in electrical communication with a controller, such that the product level determiners provide information to the controller. This invention further includes a product height profile having multiple time intervals, and a required product level for each time interval. Accordingly, the product supply management system may compare product levels to the product height profile, and determine whether additional product is required. The product height profile may include relative timing device, data set or real-time timing device to control the timing portion of the invention. Alternative embodiments are further provided.

Abstract: Vacuum insulation panels with a decreased thermal conductivity provide increased thermal effectiveness in a vessel of a product dispenser, when the vessel is substantially encapsulated with the vacuum insulation panels. The product dispenser including insulation having a reduced thermal conductivity provides the ability to convert existing manufacturer product lines from designs requiring foams with hydroflorocarbon blowing agents to foams that utilize non-hydroflorocarbon blowing agents. The vacuum insulation panels may be placed adjacent to the vessel walls, or may be adhered to the vessel walls. In an extension of this embodiment, multiple layers of vacuum insulation panels may be applied to the vessel to further increase the thermal effectiveness of the vessel. Still further, the layers of the vacuum insulation panels may be covered with an as-formed foam insulation, thereby creating a composite thermal barrier.

Abstract: A beverage dispensing system includes a cooling chamber filled with a bath of cooling fluid for cooling beverage fluids. A cooling unit, including an evaporator coil extending from the cooling unit into the cooling chamber, freezes the cooling fluid into a frozen cooling bank about the evaporator coil. Sensor units positioned at desired locations about the evaporator coil provide output corresponding to the size and shape of the frozen cooling bank. Also, a control unit reads the output from the sensor units and operates the cooling unit to regulate the growth of the frozen cooling bank. In addition, the control unit may read output from temperature sensors attached to dispensing valves or monitoring ambient temperature conditions.

Abstract: A dispenser system includes a product source, a cooling unit, an agitator, a dispensing station coupled with the product source, a sensor, and a controller. The cooling unit cools product delivered to the dispensing station from the product source. The agitator is disposed in the cooling unit and circulates cooling fluid contained in the cooling unit. The sensor measures an operating parameter of the dispenser system and outputs a signal representative thereof. The controller, responsive to the signal output by the sensor, operates the agitator at a lower speed when the signal output by the sensor indicates the dispenser system is operating in a desired stable state. Alternatively, the controller, responsive to the signal output by the sensor, operates the agitator at a higher speed when the signal output by the sensor indicates the dispenser system is not operating in the desired stable state.

Abstract: A coupler for a dispensing apparatus and method of use thereof includes a first member having a first, a second, and a third aperture. A second member is mountable on and rotatable about the first member to selectively communicate the first and second apertures with the third aperture.

Abstract: A dispenser housing includes an enclosure that receives a dispenser therein. The enclosure includes an opening that permits access to the dispenser. The dispenser housing further includes a first access member, a second access member, and a valve casing. The first access member is secured to the enclosure and is pivotally movable between a first position and a second position that provides access to the dispenser. The valve casing is secured to the enclosure and is pivotally movable between a first position and a second position that provides access to the dispenser. The second access member is positioned proximate to the first access member and is pivotally movable between a first position and a second position that provides access to the dispenser. The second access member includes a light source that illuminates the dispenser when the second access member resides in its second position.

Abstract: A carbonator and plain water booster includes a tank and a bladder mounted within the tank that separates the tank into a carbonated water chamber and a plain water chamber. The carbonated water chamber connects to a water source and a CO.sub.2 source to facilitate the forming of carbonated water, while the plain water chamber connects only to the water source. The pressure of the carbonated water and CO.sub.2 gas within the carbonated water chamber expands the bladder into the plain water chamber, resulting in the pressurizing of the water within the plain water chamber. That pressurization allows the dispensing of plain water with a beverage syrup at a pressure sufficient to maintain a proper mix ratio between the plain water and the beverage syrup.

Abstract: A beverage dispenser includes a housing that defines a cooling chamber and has dispensing nozzles mounted thereon, a water line positioned in the bottom of the cooling chamber for communicating water to the dispensing nozzles, product lines mounted in the front of the cooling chamber for communicating product to the dispensing valves, a refrigeration unit mounted over the cooling chamber that includes an evaporator coil extending into the cooling chamber, and an agitator motor mounted over the cooling chamber for driving an impeller located within the cooling chamber. The cooling chamber contains a cooling fluid, a portion of which freezes about the evaporator coil during the operation of the refrigeration unit to form a frozen cooling fluid slab.

Abstract: A carbonated beverage dispenser includes a chiller connected at an inlet to a water source and at an outlet to a cool water inlet of a mixing valve. The water source further supplies ambient temperature water to a warm water inlet of the mixing valve. The mixing valve receives the two water streams and mixes them to produce a constant temperature output water stream at an outlet. A carbonator receives the constant temperature output water stream to carbonate it. A dispensing unit including a cooling unit connects to a beverage syrup product source and the carbonator to cool the carbonated water and beverage syrup and dispense them into a suitable container, thereby forming a carbonated beverage drink. Additionally, an ice maker connects to the output of the mixing valve to receive the constant temperature output water stream to make the ice dispensed with the carbonated beverage drink.
