Abstract: A desuperheating spray chamber for use in a rocket exhaust recovery system for a nuclear thermal propulsion rocket, including a substantially-cylindrical outer tank with an upper end including an entrance port and two exhaust ports, a substantially-cylindrical shroud extending downwardly from an inner surface of the upper end of the tank, an annular inner spray ring that is both disposed within and concentric with the shroud; and an annular outer spray ring that is disposed between a side wall of the outer tank and the shroud, the annular outer ring being concentric with the shroud.

Abstract: In a network comprising a plurality of channels, at least two channels are operating at different frequencies. The fixed network equipment (FNE; 124, 126) identifies a plurality of channels present at a serving site and classifies each channel into one of a plurality of bandwidth groups. All the channels in a given bandwidth group have common roaming characteristics. The FNE periodically broadcasts information relating to at least one channel in each bandwidth group present at the serving site. The FNE further identifies least one channel present at an adjacent site. Each channel present at the adjacent site is also classified in one of the plurality of bandwidth groups. The FNE broadcasts information on loading for each bandwidth group present at the adjacent site.

Abstract: A subscriber (100) transmits data on a first data channel. While transmitting, the subscriber tracks the number of collisions it experiences on the first data channel (206). When the number of collisions reaches a threshold value, the subscriber transmits a reassignment request to move to a new data channel. Upon receipt of the reassignment request, a central processor (102) assumes that the first data channel is loaded. The central processor will then compare an incoming data rate to a value to determine if the first data channel is actually loaded, wherein the incoming data rate is measured by the central processor at the time the subscriber requested reassignment.
