Abstract: An improved data transfer system is disclosed which provides efficient information retrieval for tracking subsets of aircraft which are within larger sets applicable in general to aircraft in route and selectively retrieving information in an automated manner which is user defined for information displayed and functionality and specific for a user defined subset of aircraft.

Abstract: The invention is directed to a beverage dispensing apparatus which has a housing including a beverage container storage section. At least one beverage container from which measured amounts of beverage will be dispensed is supported in the storage section. An inclined beverage conveying channel supported by the housing has a receiving end adapted for receiving a measured amount of beverage from at least one of the containers. The other end of the beverage conveying channel is located at a height lower than the receiving end so that beverage will flow by gravity toward the delivery end of the channel where a delivery spout is located for delivering the measured amount of the beverage into the mouth of a consumer. A beverage releasing mechanism is coupled to each container in the storage section for dispensing the measured amount of beverage onto receiving end of the inclined channel.

Abstract: In an air traffic control system, an in-line, data cable interface is disclosed for air traffic control signals which provides data access for use by an external computer system while preventing the disruption of the existing air traffic control signals. The interface provides non-intrusive data access even when the conductors of the data cable interface are short circuited. An external computer system has an associated software program capable of compiling received signals from the in-line data cable interface together with signals from other data sources and displaying the signals in, upon instructions of the user, hexadecimal form, polar graphical form or table form or recording the data onto computer or floppy disk. The air traffic control data is compared with data from another source such as a noise detector to monitor aircraft noise.
