Title: Arrangement for the automatic pressure regulation of railway compressors
IPC: F04C28/08
Filed: 1945-04-13
Abstract: 590,133. Automatic control systems for railway compressors. MASCHINENFABRIK OERLIKON. April 13, 1945, No. 9291. Convention date, May 12, 1944. [Class 38 (iv)] Fluid flow control.- A systen. for maintaining the pressure constant in an air reservoir in a rail vehicle, comprises a plurality of pressure responsive devices, adjusted to operate at different pressures, which operate relays in the circuit of an electric motor driving a compressor. Relays 4, 5 are controlled by pressure responsive devices so that when the maximum pressure is reached both relays are de-energized and the compressor motor 3 stops. A slight fall of pressure operates relay 4 only and the motor runs slowly. A greater fall causes both relays to operate and the resistance 6 is short-circuited to give the maximum motor speed. In a modification, Fig. 2 (not shown), the high-speed circuit is independent of the condition of relay 4. In further modifications, the relays feed the motor from different tapping points on an auto - transformer.

Abstract: <FORM:1030614/C1/1> Phosphoric acid is concentrated, preferably to a 72% phosphorus pentoxide content corresponding to a 100% orthophosphoric acid concentration, by concentrating said acid under a vacuum of 4 to 10 mm. Hg. absolute pressure in an evaporator consisting of a surface heat transfer apparatus, the water vapour thus produced being condensed under a vacuum in a sulphuric acid still, which is then cooled.  The temperature in the evaporator is preferably between 101 DEG  and 125 DEG  C.  As shown in the drawing, phosphoric acid to be concentrated enters through feed-line 1 to evaporator 2 heated with steam, the heating water being discharged through duct 4.  The thus-produced vapour passes to separator 6 in which the water vapour is separated from the phosphoric acid, part of the acid being returned to evaporator 2 through duct 7, and that part of the required concentration being discharged through duct 8, and collected.  The water-vapour is passed to condenser 10 through duct 9 where it is condensed by the sulphuric acid circulating in condenser 10.  Fresh concentrated sulphuric acid enters condenser 10 through feed-pipe 11. Non-condensable gases may be extracted through vacuum pump 12, which also supplies the necessary vacuum in the installation.  The diluted acid passes through pipe 14 into vessel 15, from which the acid taken by pump 16 is forced through a refrigerator 17 into the upper portion of condenser 10.  Excess acid is discharged through overflow pipe 18.
