Patent GB-455692-A (GB)
Title: Improvements in production of hydroquinones
IPC: C07C37/07
Filed: 1935-04-25
Abstract: Hydroquinones of a high degree of purity are obtained by vaporizing a quinone by steam distillation passing the vapours at pressures below atmospheric and at temperatures below 95 DEG  C. into intimate contact with a stream of re-circulating liquid containing a reducing agent, and cooling the said stream to keep the temperature of the hydroquinone solution obtained at between 60 and 95 DEG  C.  The recirculating solution may be cooled by means of a cooling coil, or preferably by reducing the pressure, and thus concentrating the solution by evaporation of steam.  The hydroquinone may be crystallized in known manner.  According to an example, quinone prepared by the oxidation of aniline with manganese dioxide or dichromate and sulphuric acid, is steam-distilled from the reaction mixture and passed into a reducing mixture of iron dust and water which is circulated <PICT:0455692/IV/1> until the quinone is completely reduced, after which the solution is removed, filtered and crystallized.  In the apparatus shown, the aniline or other starting material is oxidized in a tank 1 provided with a stirrer 2, and the product pumped through a preheater 9 to a tower 11 and still 17, the whole being maintained at a reduced pressure by an eductor 26.  Steam is introduced into the mixture by a pipe 20.  The quinone vapours and steam pass through conduit 14 to the eductor 26; they there meet the reducing liquid circulating through conduit 29, reduction line 30, vacuum tank 31, and pump 32.  The products are removed by a conduit 37 to a filter-press 39.  The temperature of the quinone and steam vapours is maintained at 90--95 DEG  and the recirculated reducing mixture is maintained at 60--65 DEG  C.  A vacuum of 15--23 ins. is maintained in tank 31.  The re-circulating stream may be cooled by means of a cooling coil instead of reduced pressure. Toluquinone and xyloquinone may be reduced in a similar manner.

Abstract: 118,341. Ashworth, J. Sept. 4, 1917. Aerial machines without aerostats; propelling; steering and balancing.-An aerial machine is supported by pairs of planes 49, 50, 51, 52 yieldingly pivoted on shafts carried by rotating arms 26, 27, 31, 32, means being provided for varying the initial incidence of the planes in the same or opposite directions on the two sides of the machine. Auxiliary balancing-planes 60, 61 are operated simultaneously with the adjustment of the rotating planes, the adjustment being in the same direction as the main planes when the main planes are all moved in the same direction, but when the main planes are moved in opposite directions the planes 60 are each moved in a contrary direction to the adjacent main planes. The arms 26, 27, 31, 32 are journaled upon two sleeves 8, 9 and are driven from a motor 62 by chains 66, 67 passing over sprocket wheels on the arms 27, 31. The supporting planes are connected at each end by springs to pins 54, 55, Fig. 2, on sprocket wheels geared as shown to similar sprocket wheels on the sleeves 8, 9. The sleeves 8, 9 are mounted on a continuous shaft 3, Fig. 3, and have bevel wheels 10, 11 gearing with a wheel 15 fixed to a vertical shaft 13. A second wheel 14 gears with two wheels 6, 7 mounted on shafts 4, 5 carrying the planes 60, 61. An horizontal shaft 18 provided with a hand wheel is connected to the shaft 13 by gearing contained in a casing 16. Longitudinal movement of the shaft 18 turns the sleeves 8, 9 and varies the normal angle of the planes 49, 50, 51, 52 so as to alter the line of thrust, equally on the two sides of the machine, the planes 60, 61 being also turned in the same direction as the main planes. The centre of gravity also is moved. Rotation of the shaft 18 causes the rotating planes to be turned in opposite directions to effect steering, the planes 60, 61 being turned in opposite directions to the corresponding rotating planes to preserve lateral balance. The gearing also enables the pressures on the two sides of the machine to be automatically equalized during gusts. The car is suspended as shown from the sleeves 8, 9. Fig. 2 shows the positions which the main planes assume at different points in their cycle. When the engine stops, all the planes assume the horizontal position and their angle of incidence can be controlled during the ensuing glide.
