Title: Fault location system for use in the location of faults in both a pcm link between two terminal stations
IPC: H04B17/40
Filed: 1971-10-12
Abstract: 1369062 Testing unattended repeaters SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 12 Oct 1971 [29 Jan 1971] 47418/71 Heading H4R  In a fault location system for a two way PCM link over a number of repeater stations an interrogation pattern is transmitted from one terminal station, and detected at the other terminal to effect connection between the incoming and outgoing lines at that station. At each repeater station an efficiency detector responds to a particular respective interrogation pattern to generate a signal representative of the operational state of the detector. As described the system comprises a number of outgoing A-B lines 1 to m/2 and a number of incoming, B-A, lines m/2 to m. Fortesting, an interrogation signal having a characteristic pulse pattern with a low frequency component dependent on the particular repeater station it is desired to test, is coupled to the outgoing line at station A from generator G. At the other terminal station B the pulse pattern is detected and used to effect connection between the respective outgoing and incoming lines so that the interrogation pattern is returned to terminal station A. At each station the outputs from the amplifiers of each direction of transmission are fed to respective inputs of the filter system, shown in Fig. 3. The signals are fed via limiters L1j and L2j to diode gates d1J and d2J one or the other of which is blocked by the particular polarity of the voltage applied to the supervisory line α. The signal from the amplifier for the particular direction of transmission being tested feeds through the other gate, passes through the filter Fj to be fed over the supervisory line α to the testing terminal station as an indication of the operative state of that repeater. By reversing the potential across the line α the amplifier for the other direction of transmission is tested.

A fuel element assembly comprises a number of sleeves 1 stacked end to end and each housing a cluster of fuel elements :2 in an annular space 3 between the sleeve 1 and a centrally located tubular member 4. The fuel elements 2 are arranged in groups of three, as shown at 2 1 , 2 2 , 2 3 , and each element 2 comprises a tube, the fuel being either inside the tube or within its walls (Fig. 3, not shown). Each fuel element 2 has lugs 2a, 2b which abut against corresponding lugs on adjacent elements, against projections 1a on the wall of sleeve 1, or against the central member 4. The lugs 2a, 2b extend for the full axial length of the elements 2 or for short distances at the ends. The lower end faces of the fuel elements 2 have projections 2c in the shape of minor segments off-set with respect to the central axes of the elements. A portion of the annular space 3 is shown in Fig. 4, which Figure shows in exaggerated form the positions which the fuel elements 2 tend to take up. The projections 2c bear against flat end faces of adjacent fuel elements 2 in a corresponding group of elements in the cluster of the sleeve below. Considering the two adjacent sleeves 1 in the middle of Fig. 4, the gravitational forces due to the weights of the elements in the upper of the two sleeves act along vertical lines through the centres of gravity of the elements. These vertical lines pass outside the area of contact between adjacent elements and the result is to produce couples tending to cause the elements to lean together. The projections 2c at the lower end of the elements 2 in the uppermost sleeve are disposed so that the gravitational forces acting exert couples tending to make the elements lean away from one another. In practice, the elements will be substantially vertical but the couples acting on them are such as to resist forces tending to vibrate the elements. Each fuel element 2 may comprise a single fuel member, as shown, or a number of separate fuel members each having a similar off-set projection so that all the members of an element tend to lean in the same direction.
