Title: Local loop communication network for routing date and telephone speech signals in digital form
IPC: H04L12/43
Filed: 1983-01-25
Abstract: A local area network, e.g. serving several floors in a building, is formed from sections of transmission line (Li) coupled together via repeaters (R1, Rn), the loop being closed by a common circuit (UCB), which inter alia, provides synchronisation. Each repeater can also give access to the loop to a station or port (see below). The signals are routed in a time frame the first part of which is used in a packet switching mode and the second part of which is used in a circuit switching mode. To increase the telephone traffic capacity, telephone ports (P1, P2, P3, P4) are provided at various points of the loop to purge it of the 8-bit bytes used in the second segment of the time frame. A port does this by removing bytes circulating upstream of that port, and inserting bytes for circulators towards a downstream port or station into the loop. A time switch (CT) interconnects the loop sector and the outside world, public exchange or PBX, under control of a common control circuit (UCT).

Title: Nuclear fuel rod straightness measuring system and method
IPC: G01B7/00
Filed: 1984-01-10
Abstract: A rod straightness measuring system and method. A rod, such as a nuclear fuel rod, is supported and rotated in such a manner that if the rod were straight, it would be rotated about its longitudinal axis and remain straight without transverse translational motion, and in such a manner that if the rod were cambered, it would remain so cambered while supported and rotated. A multiplicity of separated and fixed range finders are placed apart from and directed towards the rod so that they would be directed perpendicular to a straight rod's longitudinal axis. The range finders measure the distance to the rotating rod. Differences in maximum and minimum measurements for each range finder indicate the degree of straightness of the rod. In a preferred system and method, the range finders are placed at known distances from a straight rod, and differences in distance measurements from the known distances for each range finder indicate the degree of rod straightness.
