Title: Process for the recovery of ammonia and sulphur dioxide
IPC: C01B17/58
Filed: 1962-08-28
Abstract: NH3 and SO2 are produced from ammonium sulphate, ammonium bisulphate, or liquids containing these salts and/or ammonium sulphonates dissolved in sulphuric acid and water by a process wherein the molten salt or the solution is sprayed, with the exclusion of air into a chamber in which excess of coal, coke or charcoal is maintained between 370 DEG  and 390 DEG  C. The chamber may be heated by gases generated in burning gas or oil, and freed from oxygen by passing through incandescent coke.  The gaseous reaction products which include NH3, SO2, CO2, N2 and steam may be separated either by absorbing the NH3 in ammonium bisulphate or by absorbing the CO2 and SO2 in MgO or alkaline earth oxides.  In either case the absorbed gas can be recovered by heating and the reactivated absorbent recycled. SO2/CO2 mixtures can be used to prepare sulphuric acid without separation.

The tool is fed into the work by moving forward the shank 1 when a roller 12 on a pin 11 held in the plunger 8 moves along a helical groove 2a in the extension 2 of the shank, thereby rotating the plunger. An adjustable or fixed stop may limit the motion. In a modification the portion 1 may be replaced by a cylindrical block drilled eccentrically for the reception of the plunger &c. Tools.-The tool may be of the form shown in Fig. 6, a fresh tooth being turned into operation when one is blunt. A multiple cutter mounted on a single shank may be employed if necessary.
Patent GB-396375-A (GB)
Title: Improvements in or relating to the synthesis of formic acid
IPC: C07C51/10
Filed: 1931-12-01
Abstract: Formic acid is produced by the reaction of carbon monoxide on water or steam in presence of an acid or acid substance and of a substance capable of absorbing carbon monoxide such as cuprous chloride or silver nitrate.  Suitable acid substances are lower fatty acids such as acetic acid, hydrochloric acid, chromic acid and tungstic acid. The reaction may be effected by passing a mixture of carbon monoxide and steam through the acid or its solution containing cuprous chloride or the like.  Carbon monoxide may be used without steam when the catalyst contains water, and acid vapour such as hydrochloric acid may be added to the gas. Alternatively a mixture of carbon monoxide, steam and acetic or hydrochloric acid may be passed through a reaction zone containing cuprous chloride or the like, which may be supported on a carrier such as pumice kieselguhr or carborundum.  In another modification the reaction mixture may be passed over solid tungstic or chromic acid mixed with cuprous chloride or the like, and these substances may be supported on carriers.  The carbon monoxide may be pure or dilute, and may be free from sulphur compounds.  In an example a mixture of equal volumes of carbon monoxide and steam is passed through anhydrous acetic acid containing cuprous chloride at 220 DEG  C. and 15 atmospheres pressure.

Abstract: 664,843. Pulse generating circuits. ENGLISH ELECTRIC CO., Ltd. Dec. 23, 1949 [Dec. 31, 1948], No. 33623/48. Class 40 (vi). In a high-voltage pulse generator in which a first capacitor charged from an A.C. source through a transformer is discharged through a load in series with the anode-cathode path of a discharge tube by a very heavy current pulse of some microseconds duration, the tube has a mercury pool cathode and is provided with means to discharge a second capacitor through a second anode to cathode path by a current pulse which subsists for a period of some hundreds of micro-seconds prior to the pulse discharging the first capacitor. The Figure shows a pulse generator for a radar transmitter in which the capacitative pulse forming network 10 is charged to a very high voltage periodically from the A.C. source 12 via step-up transformer 11 and is discharged periodically by a very short duration current pulse through the load 13 via the anode 14 to cathode 15 path of the mercury pool cathode discharge tube. The tube has a push-button operated igniter 16 which strikes an excitation arc to anode 18. In order to prevent the heavy current flow in the path 15, 14 when capacitor 10 is discharged from extinguishing the excitation arc a capacitor 20 which has charged from the D.C. source 21 via inductor 22 is discharged via inductor and the anode 19 to cathode 15 path of the tube just prior to the discharge of capacitor 10. The discharge current of capacitor 20 is preferably sinusoidal and capacitor 10 is discharged at the occurrence of the peak of the wave. The control electrodes 24, 25 are triggered by bias sources 33, 35 controlled by pulse generators 32, 34, respectively, the correct timing being obtained by triggering generators 32, 34 from an auxiliary A.C. source 30 coupled to source 12 via the phase-shifting network 31 and delay network 36 respectively.
