Title: Improvements in or relating to the manufacture of highly concentrated nitric acid
Inventor: HOBLER THADDAUS
IPC: C01B21/46
Filed: 1935-08-13
Abstract: <PICT:0447952/III/1> Concentrated nitric acid is obtained from dilute nitric acid by the three following steps: (1) reacting diluted nitric acid with nitric oxide obtained in the second step to produce nitrogen tetroxide and water; (2) dissociating a portion of the nitrogen tetroxide obtained in the first step into nitric oxide which is employed in the first step and oxygen; (3) the reaction of the remainder of the nitrogen tetroxide from the first step with oxygen from the second step in the presence of water to produce concentrated nitric acid.  As shown, 50 per cent nitric acid from ammonia oxidation absorption flows through a pipe 1 into a packed absorption tower 2, provided with temperature regulating coolers 3 and 4, hot dissociated gases from the bottom of a dissociation furnace 9 entering the bottom of the tower through a short pipe 8. Water containing a little undecomposed acid leaves through a pipe 10 while part of the gases enriched with nitrogen tetroxide are removed through a pipe 5 by means of an injector 6 and are decomposed in the furnace 9 for return to the tower 2 via pipe 8. The excess of gases containing NO2 and oxygen together with water vapour and nitric acid are withdrawn from the top of the column 2 through a pipe 16 by means of a vacuum pump 17.  This pump maintains a pressure of about 0,1 atmosphere in the circulation system.  A part of the withdrawn gases is forced under pressure into the injector 6 while the remainder enters a cooler 19 via a pipe 18.  A condensate of 60--70 per cent nitric acid separates in the cooler and is led with the uncondensed gases via a pipe 20 into a pump 21 which pumps them at a pressure of 20--50 atmospheres into a pressure column 23.  The components react in the column 23 to produce 98 per cent nitric acid which is led to a tank 24, while uncondensed gases are returned to the system through a pipe 25.  A cooler 26 is provided at the top of the column 23.  If desired, the temperature in the column 2 can be adjusted to give an insufficient water content to the gases for the production of nitric acid, the balance of the necessary water being added in the form of dilute nitric acid through a pipe 14.

Title: Improvements in steering devices for toy-vehicles
IPC: B62B3/00
Filed: 1945-09-10
Abstract: 598,786. Toy vehicles. HUARD, G. G., and ROGER, R. J. E. Sept. 10, 1945, No. 23276. Convention date, March 29, 1944. [Class 132 (iii)] A steering device for toy vehicles comprises steering control means supported on a fluted column or on a smooth column bearing a pinion which is held in a support, and the teeth formed by the flutings or on the pinion being constantly in mesh with those of a quadrant toothed externally or internally, the said quadrant pivoting on a fixed part of the vehicle, and being itself in engagement with the means to be controlled such as the steering trapeze of an automobile carriage. The quadrant 7, which in Fig. 1 is shown with internal teeth 8 is articulated by a pin 9 on a part of the vehicle 6. A hollow 10 is formed in its lower portion, and this hollow engages a lug 11 on the coupling bar 12 which, together with the arms 13 and 14 forms the steering trapeze which operates the wheels 2 and 3. The coupling bar 12 may be formed from a strip of metal bent into a U, in which case the lug may be on either of the arms of the U, or it may be formed together with the lug out of a single solid piece of metal. When the steering control 4 is rotated to the right, the teeth 5 being engaged in those 8 on the quadrant cause the wheels to be locked to the right. Should the quadrant be toothed externally (Fig. 4) the wheels are locked to the left on turning the steering control to the right. The extent of the lock is limited by the provision of a hollow 26 of predetermined length, so that when the lug I1 contacts the flanks of the hollow further movement is prevented. A similar effect is obtained with a hollow quadrant when the steering column butts on to the ends of the hollow provided in the quadrant. A further modification to limit the lock consists in arranging the flanks of the support 6 in such a manner that the arms 13 and 14 may butt against them. The movement of the bar 12 may alsc be controlled by placing the lug on the quadrant (Fig. 4) to operate directly in a slot in the bar 12.
