Patent GB-498898-A (GB)
Title: Improvements in the manufacture and production of concentrated nitric acid
IPC: C01B21/26
Filed: 1937-07-16
Abstract: In the production of concentrated nitric acid from gases containing nitric oxide by absorbing them in concentrated sulphuric acid and separating the formed nitric acid by distillation, the gases are dried to a great extent and the oxides of nitrogen contained therein are oxidized by means of air or oxygen to nitrogen tetroxide before the absorption, and after the absorption the nitric acid is first distilled off from the sulphuric acid under reduced pressure and then lower oxides of nitrogen are expelled by heating the residual acid in the presence of water or dilute nitric acid in the liquid or vapour state, the lower oxides of nitrogen being subjected to the treatment again after the addition of air or oxygen.  The oxidation of the initial gases may be completed by a treatment with oxygen or with concentrated nitric acid.  Catalytic agents such as silica gel, which at the same time effects a drying of the gases, may also be used. The treatment with water or dilute nitric acid may be carried out so as to obtain a practically denitrated sulphuric acid of 95-96 per cent.  The vacuum distillation to remove the nitric acid may be conducted at 100 DEG  C. and the expelled vapours, if desired together with an addition of air, may be lead in counter-current to the distilled-off acid which has already been condensed.  The uncondensed gas may be washed under high vacuum with concentrated sulphuric acid.

Abstract: 1,245,511. Wood-pulp liquor; recovery of salts. CHEMICAL CONSTRUCTION CORP. 17 April. 1969 [23 April, 1968], No. 19790/69. Heading B1B. Salts are recovered in the form of particles from waste wood-pulp liquor by introducing it through line 1 into evaporator 2 where the liquor is contacted with hot air, supplied through inlet 10, whereby part of the water is evaporated, passing partly-concentrated liquor through line 6 to evaporator 12 where it is further concentrated by contact with hot flue gas, burning concentrated liquor with air in fluidized bed reactor 19, passing the flue gas through line 17 to evaporator 12, and withdrawing the required salts (Na 2 SO 4 , Na 2 CO 3 ) from the reactor through line 22. Evaporator 2 contains a frusto-conical baffle 3 to which the liquor is recycled through line 5, and over which it flows as a liquid-film. The velocity of gas-flow is accelerated towards the lower rim of baffle 3, and the liquid-film is dispersed into droplets in the gas. Evaporator 12 operates in the same manner. Steam may be mixed with the air before it is introduced through inlet 10 into evaporator 2. Solid particles are maintained in fluid motion in the reactor by introducing combustion air into the bottom. In an alternative plant, the flue gas leaving evaporator 12 is reheated and used, instead of air, as contact-medium in evaporator 2.

Abstract: 478,741. Machines for making ropes &c. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., and BEE, J. R. July 24, 1936, No. 20693. [Class 109] In twine-laying &c. machines additional brake mechanism, acting on the bobbins when the machine is stopped, is used to prevent overrunning. The ordinary brake or drag device consists of a plate 12 carrying spring pins 12a taking into the head 2d of each bobbin 2. The plate is fixed to hubs 13a projecting from a brake disc 13 mounted on the hub 14a of a disc 14. Another disc 15 mounted on the hub 14a is connected to an arm 16 fixed to the hub 14a. The arm 16 works over a fixed bar 17 and the hub 14a is mounted on the hub 2a of the bobbin 2. The additional brakes comprise bars 19 mounted in threes on shafts 20. The brakes are connected to the stop-motion. When the stop-motion is operated each brake surface 19a comes down on a flange 13b of the corresponding disc 13 and prevents overrunning. The stop-motion is operated by failure of the twine supply. When this occurs a detector lever 30a, 30b or 30c normally retained in position by the twines moves clockwise on its pivot and brings its counterweight 30 into engagement with a lever 29. A trip device acting on beltshifting mechanism and on the additional brakes is thus put into action.
