Abstract: The present invention is a radio communications system. The system includes a first Line-Replaceable Unit (LRU) and a second Line-Replaceable Unit (LRU). Each LRU includes two transmitters, a multi-channel receiver, a passive hybrid combiner-splitter, and a bypass relay. The first LRU and the second LRU are communicatively coupled via a crosslink connection, such as a coax cable connection. The system includes first and second antennas, which are communicatively coupled with the first and second LRUs respectively. The system includes a crosslink bus configured for communicatively coupling the first and second LRUs, thereby allowing the LRUs to coordinate operation of the relays via the crosslink bus. Still further, the system is configured for providing concurrent transmit and receive operation.

Abstract: An improved bulk storage system for fluids supplied to a dispensing system by a fluid line. The bulk storage system includes a receptacle with a first portal and a second portal. A substantially nonpermeable bag is positioned within the receptacle for storing and dispensing fluids therefrom. The bag includes a first passageway positioned adjacent to the first portal of the receptacle and a second passageway positioned adjacent to the second portal of the receptacle. A support device is positioned adjacent to the receptacle. The first passageway of the bag is attached to the support device and the second passageway of the bag is attached to the fluid line such that fluids in the bag flow through the second passageway to the dispensing system.

Abstract: A package for dispensing a carbonated beverage pre-mix at a controlled flow rate in the micro-gravity conditions of outer space comprising a rigid outer container, a collapsible bag in the container, and an adjustable flow rate control valve. Positive pressure is applied to the collapsible container by CO.sub.2 gas in the container surrounding the bag to assist the dispensing of the pre-mix therefrom. The pre-mix is dispensed from a spout, directly into an astronaut's mouth upon actuation of a lever disposed on the top of the package.
