Title: Improvements in or relating to long distance telecommunication exchanges
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04Q3/00
Filed: 1947-05-09
Abstract: 639,141. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. May 9, 1947, No. 12622. [Class 40 (iv)] In a V. F. signalling system in which longdistance calls are set up over one or more tandem exchanges, each exchange on receiving a forward release signal causes a fault signal to be reverted and/or an alarm given unless it receives a signal indicating that the succeeding exchanges have responded to the release signal. The alarm or fault signal is also given on receipt of a signal indicating the release at the succeeding exchange if the exchange in question has not responded to the forward release signal. A tandem or end exchange receiving a backward fault signal does not release but gives an alarm and in the case of the former reverts a fault signal. As shown, Fig. 3, the forward release signal received over the pair ABJ (E-W) of a 4-wire junction momentarily operates TRA, TRB and OKU comes up during the release period of TRB. A short signal received over BCJ (W-E) indicating release at the succeeding exchange momentarily operates TSA, TSB to bring up OKD. Relay COK thereupon operates to de-energize the release relay B during whose release period a short signal is reverted over ABJ (W-E). If, however OKD does not operate within a predetermined period, either due to the non- receipt of a backward signal or due to the receipt of a long backward signal, slow-tooperate relay DP pulls up, holds the release relay operated and energizes ALR to revert a continuous V.F. signal and sound a local alarm. Relay OKU disconnects the backward transmission path to prevent through transmission of the backward signals. The alarm relay ALR is brought up immediately if OKD operates due to release of the succeeding exchange when OKU has not responded to the forward release signal. At the originating exchange, by a somewhat similar arrangement, Fig. 2 (not shown), release is caused when a short V.F. signal is received, but a long V.F. fault signal from the succeeding exchange prevents release and gives an alarm. If preferred, the circuit of Fig. 3 may be modified so that the long alarm signal is reverted if only OKD operates, whereas the local alarm is given if only OKU operates.

Abstract: <PICT:0614312/III/1> <PICT:0614312/III/2> <PICT:0614312/III/3> <PICT:0614312/III/4> Sugar solutions &c. are evaporated in two stages in an evaporator comprising upper and lower concentric calandria Z1-Z4, E1-E4, the lower calandria having a smaller number of tubes than the upper and being heated sufficiently to vaporize sufficient liquid to emulsify the remainder, whereupon the emulsified liquid and vapours are delivered to the upper calandria where the evaporation is completed.  If desired, the liquid can also be emulsified in the lower calandria by vapours, e.g. steam, introduced through nozzles I aligned with the lower openings of the tubes Q1 of the lower calandria E.  Two or more effects may be connected together in multiple effect (Fig. 1), the residual liquid separated in the separator M1 of the first effect flowing down the central downcomer B1 and thence through tube GC1 into the second effect while the vapours from the separator M1 pass through tubes St1 to the heater E2 of the second effect.  The first effect is heated by steam passed through line St to the upper calandria and through T1 to an annular heater U surrounding the lower calandria. The heater U comprises groups of tubes arranged in parallel in spaces Q, Fig. 5, through which tubes the solution circulates in series as shown in Figs. 6, 7, while the steam passes laterally through the space, entering through aperture b and dividing into two currents flowing through the spaces on the right and on the left respectively of the aperture b and being finally re-united in spaces Ko, Lo from which vapours and condensate are removed through tubes K, L.  The solution enters through pipe GD, circulates alternately upwardly and downwardly through the groups of tubes and leaves through a space e, Fig. 6, to enter into the bottom ends of the tubes Q1 of the lower calandria CI, Fig. 3, from a space Io which is closed at the bottom by a nozzle Y carrying the nozzles I, the solution thus arriving at the tubes Q1 at the same time as the injected vapour used to emulsify it.  In moving from b to a, the vapour goes through limited apertures d1 ... d11 and d11 ... d111, whose total section is decreased in proportion to the vapour condensed so that the vapour velocity is controlled.  The upper and lower heads Ds, Di of the heater are arranged to connect two adjacent sets of tubes together and a metal cylinder J in each of the channels C causes a circular flow of vapour.
