Abstract: 994,238. Line transmission systems; fault locating. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 6, 1963 [May 9, 1962], No. 17823/63. Heading H4R. In a transmission circuit including attended and unattended repeaters each unattended repeater includes a shunt impedance bridging the line and each attended repeater has an impedance measuring device in order that a break in the line may be located by a measurement of the impedance across the line. Fig. 1 shows a carrier telephone system comprising a source of carrier telephone signals 1 feeding a coaxial line 2, 3, 4, with intermediate unattended repeater amplifiers 5 and 6; power to the repeaters being fed over the line from a source 7, the carrier signals and the power supply being isolated at the repeaters by high and low pass filters 10, 11, 12, 13, 14, 15, 16, 17. The power flows through all the repeaters in series while Zener diodes 26 and 27 ensure continuity of the power supply circuit if one of the amplifiers is removed from circuit or develops a fault. Resistors 28 and 29 are in a eluded in the power circuit, the values being chosen to be less than the insulation resistance of the cable but higher than the series impedance of the conductors. In operation, should a break occur in any of the cable sections the impedance measuring device 30, measuring the impedance between the conductors of the cable, will indicate how many shunt impedances such as 28 or 29 remain in circuit and hence in which of the cable sections the break occurs. Subsequently the exact location of the fault may be determined by isolating the faulty section by means of switches 33, 34, and measuring either the capacity or the pulse echo time of the section of cable up to the break by means of a capacitance bridge or a pulse source and delay measuring apparatus 31, 32. In a modification, Fig. 2 (not shown) the shunt resistors 28, 29 have rectifier connected in series so that with normal power supply the diodes are back biased and the resistors absorb no current, for fault location the power supply is reversed so the rectifiers conduct and the fault is located as before.

Title: Improvements in and relating to conveying mechanisms
IPC: B65G15/40
Filed: 1934-06-18
Abstract: 444,472. Raising liquids. JOHNS, H. S., 369, Bay Street, North, Hamilton, Ontario, Canada. June 18, 1934, No. 18050. [Class 102 (ii)] [See also Group XXX] A water-raising device comprises a moving tube formed by a pair of rubber or like belts 1, 2, Fig. 8, running face-to-face, one or both of the belts having a material-carrying cavity therein, and each of them being constructed so as to be capable of being flexed in all directions along its length. The belts may be twisted between pulleys, as shown in Fig. 9, to assist in keeping the belt faces together. In the construction shown in Fig. 8 each belt comprises a soft pliable rubber part 25 and a harder or tougher part 26. Each belt is formed with a rib 4, reinforced by a fabric core 24 which resists stretching of the belt, and a pair of flanges 5 which fit against the flanges of the other belt. To assist in keeping the belt faces together they are formed with one or more tongues and grooves 14, the flexibility of the rubber permitting the tongues to enter the grooves when the belts are stretched in passing over pulleys. Teeth 27 may be formed on the edges of the belts to prevent relative e longitudinal movement between them. When the belts are face-to-face the flanges 5 form the equivalent of the ribs 4, and the guiding pulleys 9, Fig. 6, are formed with grooves 7 to receive a pair of flanges, the belts being passed edgewise round the pulleys in order to ensure that each belt is similarly stretched. The belts may be shaped, as shown in Fig. 18, to form an octagonal tube. The conveyer is loaded or unloaded by separating one or both edges of the belts. In the construction shown in Fig. 3 the belts, after passing over a common pulley 9, pass over separate pulleys 15, 16 away from each other so that the material is discharged between them. In the construction shown in Figs. 10 and 13 the belts are separated at one edge by a wedging roller 18 carried by a lever 19. Complete separation of the belts is prevented by rollers 21 which are also carried by the lever 19 and engage the ribs 4 in the upward movement of the lever and the wedging roller. Upward movement of the belts is prevented by means of rollers 23 engagmg the top edge. The' belts are similarly separated or opened for loading purposes. For use in conveying material in a vertical or inclined direction transverse partitions 28, Fig. 13, may be formed in the belts. Liquids may be raised, as shown in Fig. 15, by belts passing over submerged pulleys 29, 30.
