Title: Device for checking the continuity of a communication path between two terminals
IPC: H04Q11/04
Filed: 1975-10-28
Abstract: 1510498 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 28 Oct 1975 [6 Nov 1974] 44345/75 Heading H4K In order to perform a loop test through a time division switching centre and an analog switching centre a generator generates in the time division centre coded samples of an AC loop check signal the frequency of which is a sub-multiple of the frame time of the digital centre, the samples are transmitted (via a digital to analog converter) to the analog switching centre which loops the line returning the signals (via an analog to digital converter) to the digital centre where it is recognized as the returned signal if it satisfies three tests i.e. that the sum of the samples is approximately zero, that at least one of the samples is of at least a predetermined minimum value W I and that none of the samples is of more than a maximum value W2. The tests are independent of phase changes due to sampling delays caused by the conversions. The figure shows a receiver circuit for performing these tests. It includes a store 6 having a row for each channel for which a loop test can be performed, an input A for 8 bit P.C.M. samples, an adder 9 which adds each sample to the corresponding accumulated total stored in the first 8 bits of the corresponding row of the store 6 and recirculated via the register 7' and the adder, a comparator 19 which compares each sample with the value W1 and if a sample of magnitude greater than W1 is detected sets the penultimate bit of the corresponding row to "1", and a comparator 20 which compares the samples with the value W2 and if any sample exceeds this value sets the last bit of the corresponding row to "1". At the end of an accumulation cycle a comparator 8' checks that the accumulated totals are approximately zero (not greater than a given error value applied at e) and an AND gate 13 is enabled if the three tests are met. Gates 14, 17 and 18 operate if the corresponding tests fail.

Abstract: 1,031,438. Closed-circuit heating systems. HUPP CORPORATION. Nov. 15, 1963 [Nov. 15, 1962], No. 45256/63. Heading F4U. In a closed heating system in which an organic liquid is heated in unit 10 and passes to and from at least one heat using unit, e.g. 12, 14, 16, through supply and return conduits 62, 64, 22, means are provided to keep the velocity of the liquid through the heating unit 10 constant, and further means rapidly cool the liquid on shut-down of the system, to avoid overheating the liquid. On starting the system the liquid is diverted through filter 32, pressure gauges 46 and 44 indicating the occurrence of clogging. After heating, some liquid is drawn from supply line 62 by pumps 78 and passes through the parallelly connected heat using units 12, 14, 16. Each means 74 is responsive to the temperature of the respective unit and operates a three-way . valve 82 to divert liquid through conduit 84 for recirculation through the unit when the temperature of the unit reaches a required value. The units may be maintained at different temperatures. Valve 58 in the fuel line 56 is controlled by temperature-sensitive device 60 and maintains the temperature of the discharged liquid constant. The velocity of the liquid through unit 10 is maintained constant both by valve 85 controlled by pressure-sensitive device 86 and by by-pass valve 90 in by-pass 88 which is controlled by pressure-sensitive device 92. The differential pressure switch 98 connected across pump 30 operates alarm 100 when the flow rate decreases below a predetermined value. On shut-down the flow of liquid through units 12, 14, 16 and fuel into unit 10 are shut off together. The returning liquid is then diverted through cooling unit 106 and thence into the heating unit 10 to cool the still radiating lining in the unit 10. The cool liquid may be diverted into the units 12, 14, 16 to cool them also. Finally the power source 122 is disconnected from pump 30 by switch 120, overriding means 124 responsive to the temperature of the liquid discharged from unit 10 maintaining the electrical circuit until the temperature falls below a given value.
