Title: Improvements in or relating to the de-acidification of ammonia water
IPC: C10K1/12
Filed: 1958-05-09
Abstract: In a method for the de-acidification of ammonia water under pressure in stainless steel columns, particularly for de-acidifying the 2-8% wash water produced from hydrogen sulphide scrubbing, a temperature of 70-105 DEG  C. is maintained at the head of the pressure de-acidifier according to the pressure conditions, the ammonia supplied being drawn off in part in the form of hot vapours via a pressure reduction valve and this is worked up in a column under normal pressure in known manner.  In a preferred embodiment 4% ammonia water preheated to 90 DEG  C. at 6-8 atmospheres enters the de-acidifier which is heated at the bottom to 160 DEG  C. through pipes 1.  De-acidified ammonia water heated to 160 DEG  C. is withdrawn via a pipe 3 and serves for preheating the crude water in the heat exchanger <PICT:0836315/III/1> 4.  Part of the hot vapours formed in the column is led off via the valve 6 into the normal pressure part 7 of the de-acidifier which is cooled by means of cooling pipes 8 as well as by cold non de-acidified ammonia water, supplied by the pipe 9 at normal temperature.  Acid vapours leave the de-acidifier via the pipe 10. Ammonia water collecting at the bottom of the de-acidification part 7 is drawn off by a pipe 13 cooled, and mixed if necessary with a part of the non de-acidified ammonia; water is supplied by the pipe 14 to the head of the de-acidification part 2.  If cooling is not required the ammonia water is combined with preheated non de-acidified ammonia water supplied via the pipe 15 or non-preheated non-de-acidified ammonia water which is supplied via the pipe 1 to the pressure de-acidification part.

Filed: 1940-10-11
Abstract: 544,448. Telegraph repeaters. STANDARD TELEPHONES & CABLES, Ltd., and HAIGH, L. B. Oct. 11, 1940, No. 15169. [Class 40 (iii)] In a telegraph repeater, particularly for startstop teleprinter signals in which each train comprises a start impulse consisting of a spacing pulse, as well as the usual code reversals, the repeater transmits a short marking pulse before the start spacing pulse of each tram. The repeater described is adapted for two-way working, impulses received over line L being repeated in the usual way by relay R to line P. Teleprinter signals are repeated by the armature E1 (of a relay not shown) and relays A, T to the line L. Normally, armature El connects + to relays SS, T, keeping the armatures of these relays in the position shown. When armature E1 is moved by a spacing pulse to -, relay A energizes quickly and connects + to line L until it is cut off by the slow-acting relay T which connects - to line L over armature T1. Relay SS also causes a quick-acting but slow-release relay C, to disconnect relay A from the armature E1 and connect it in series with a slow-release relay C, relay A remaining energized so that successive reversals are repeated by relay T to line L with a full reversal of potential. Relay B does not release during any marking impulse in the train, but on the receipt of the prolonged marking pulse at the end of the train, relay B releases, thereby disconnecting relay C and again connecting relay A to armature El. Line L is thus discharged over T1, A1, Cl during the release of slow-release relay C.
