Abstract: A machine for dispensing blended iced beverages is characterized by a cabinet for storing a plurality of supplies of beverage ingredients and a refrigeration system for chilling an interior of the cabinet to chill the beverage ingredient supplies. A duct extends between the cabinet interior and a remote point of delivery of the beverage ingredients and a tubing bundle extends from the supplies and through the duct to the delivery point to deliver beverage ingredients from the supplies to the delivery point. The interior of the duct is chilled to chill the tubing bundle and beverage ingredients in the tubing bundle, so that chilled beverage ingredients are always provided to the point of delivery, even when the machine is idle for an extended period of time. Various techniques are provided for chilling the interior of the duct.

Abstract: An averaging pitot tube for measuring fluid flow in a pipe or conduit, is disclosed, including an integral head connected by a transition to a sensing tube or probe. The probe is insertable through the conduit or pipe in which fluid flow occurs to measure an upstream high pressure and a downstream low pressure. Upstream holes are formed in the probe to communicate high pressure into a high pressure chamber in the probe. Downstream holes are also formed in the probe to communicate a low pressure into a low pressure chamber in the probe. Valves placed in the integral head selectively open and close the high and low pressure passageways that communicate with the high and low pressure chambers. A measurement device is selectively connectable to the integral head and is in fluid communication with said high and low pressure passageways to make measurements of flow dependent upon the difference between the high and low pressure. Tube fittings placed in the head are disclosed for reducing leaks in the system.
