Title: Improvements in and relating to the production of ammonium sulphate
Inventor: GERRARD JOHN STANTON
IPC: C01C1/246
Filed: 1960-03-05
Abstract: Ammonium sulphate and sulphur are obtained from flue gas washing liquor containing ammonium sulphite and bisulphite by addition of sulphuric acid, passing the mixture through a preheater and thence to the reaction zone of a reactor wherein part of the reacted liquor is returned to the inlet of the reaction zone and mixed with the fresh liquor so as to maintain the proportion of acid to reactants.  The amount of sulphuric acid required in the liquor may be 0,147 gram molecules per litre and the proportion of acid returned to the inlet 0,1 gram molecules per litre.  The preheater may be at 150 DEG  C. and the pressure in the reaction zone between 150 and 200 p.s.i.  The liquor enters the steam-heated preheater coil 26 through conduit 51 and then to the reaction vessel 11 of the type described in Specification 903,821.  It enters reaction tube 30 through Venturi 33, which causes a reduction in pressure at the throat and hence liquor from space 31 is sucked down into tube 30.  The liquor circulates up through return tubes 36 back to <PICT:0903822/III/1> space 31 and mixes with fresh liquor.  The excess liquor which is not returned flows over baffle 37 and out through conduit 29. Large sulphur globules follow this latter course while small globules tend to be recirculated until they grow larger.  The whole of the reaction apparatus is provided with a steam jacket. The reacted liquor and sulphur pass through a steam jacket 47 to keep the sulphur molten, and into a sulphur separator 12.  The ammonium sulphate liquor and sulphur flow over cone 46 and the sulphur sinks to the bottom of the vessel, which is provided with a steam jacket.  Sulphur is removed via conduit 41 and ammonium sulphate liquor via conduit 44. Specification 852,024 also is referred to.

Title: A transistor inverter for supplying fluorescent lamps from a direct-current source
IPC: H05B41/282
Filed: 1959-03-09
Abstract: 897,154. Discharge lamp circuits; regulation automatic. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. March 9, 1959 [March 10, 1958], No. 8059/59. Class 38 (4). An arrangement for energizing fluorescent lamps from a D.C. supply, comprises a known transistor inverter I driving a transistor pushpull amplifier II, the output voltage of the latter being limited to 20 to 40 volts above the operating voltage of the lamps to reduce the size of the chokes. The inverter has a voltageresponsive circuit varying the frequency at a greater rate than the D.C. supply to provide constant lamp current. The circuit comprises a secondary winding of a coupling transformer 1 connected to a rectifier 16a controlling a transistor 15a which regulates another transistor 13a variably shunting a resistor in series with the base of transistor 22a. A similar circuit variably shunts a resistor connected to the base of a transistor 22b. Two or more transistors may be connected in series or parallel in the inverter and/or amplifier to provide for higher voltage and current conditions. The amplifier transistors are provided with current transformers 5a, 5b in their outputs, feeding back positively into the base circuits so that the base and collector currents are proportional to minimize losses. Equalization of the base and collector currents is assisted by series resistors 6a, 6b, 9a, 9b, &c. The arrangement may be adapted for use on a higher D.C. voltage by connecting transistors in series across taps on the primary and secondary windings of the transformer 1.

Title: Improvements in vacuum treatment of coking coals
IPC: C10L9/02
Filed: 1941-07-02
Abstract: 547,115. Coking processes ; materials for making coke and other products. AMERICAN CYANAMID CO. July 2, 1941, No. 8361. Convention date, July 2, 1940. [Classes 55 (i) and 55 (ii)] The coking characteristics of caking coal are altered by drying the powdered coal and subjecting it to vacuum (e.g. 28 inches of mercury) for about 15 minutes, releasing the vacuum, and allowing contact of the coal with air for about 30 minutes, followed by a second vacuum treatment for about 15 minutes while maintaining the coal at about 150‹ C. during the whole treatment. Powdered coal treated in this way may be used in the manufacture of briquettes, sulphite liquor, coal tar, or pitch forming a binder, and undue swelling of the briquettes when carbonized being avoided. Coal is ground to pass a 20 mesh screen in a pulverizer 1 the temperature of which is controlled by hot flue gases from a furnace 4. Air from a fan 3 carries the coal particles through a pipe 6 to a cyclone separator 7 from which the hot air returns to the fan 3, and the hot and dry deposited coal is delivered by a pump 10 and pipe 11 to vessels 14. A smaller fan 8 removes air from the main current, and blows it through a collector 9 from which the coal returns to the pulverizer. The coal is aerated by hot air from pipe 12. The vessels 14, when filled, are subjected to a vacuum of 28 inches of mercury insulation in the vessels maintaining the temperature at 150‹ C. The vacuum is broken after 15 minutes, and air is admitted, the pressure remaining at atmospheric for 30 minutes, after which, a further vacuum treatment takes place. Air under high pressure may be admitted instead of air at atmospheric pressure. The treated coal is discharged into a bin 16.

The sulphur may be added to the product obtained by mixing or milling a conversion agent into the rubber sheeting and heating, and the sulphur may be in the form of a vulcanizing type accelerator such as tetramethylthiuramdisulphide.

Title: Apparatus and the method for maintaining the efficiency of the screening of particulars under varying conditions of moisture content
IPC: B07B1/55
Filed: 1962-03-06
Abstract: The screening arrangement of Specification 923,088, in which an air blower reciprocates over the screen to break up clogging material, is modified by the provision of a humidity control in the air supply to the blower.  To humidify the air, should the dryness of the material being screened be such as to cause clogging, the air supply is bubbled through water.  Where conditions of frost produce clogging, the air supply may be heated to break up the frosted material on the screen.  Reference has been directed by the Comptroller to Specification 923,088.
