Title: Auger filler and control therefor
IPC: B65B1/30
Filed: 1970-04-08
Abstract: 1,261,847. Screw conveyers. HAYSSEN MFG. CO. 8 April, 1970 [10 April, 1969], No. 16771/70. Heading B8A.  Fluent material is metered out of a hopper 21 by an auger 133, the output being a function of the number of revolutions of the auger 133. The auger 133 is driven :by an electric motor 17 through an electromagnetic clutch and brake unit 19 and a gearbox 89 giving a reduction ratio of from 1-5 : 1 to 2-0 : 1, so that the auger 133 rotates at a slower speed than that of the clutch output shaft 55. A. conventional counter 153 counts the revolutions of the clutch output shaft 55 to control the amount metered out by the auger 133 by operating the clutch and brake unit 19. The clutch and brake unit 19 has a rated voltage and a rated torque, the rated torque being substantially in excess of that required for driving the auger 133. On start-up of a cycle the clutch winding is energized at a voltage CV1 substantially in excess of the rated voltage and is then dropped, CV2, to a holding voltage CV3 substantially below the rated voltage but sufficient for development of augerdriving torque. Similarly the brake winding is energized, for rapid stopping, at a voltage BV1 1 substantially in excess of the rated voltage and then the voltage is dropped, BV2, to a holding voltage BV3 substantially below the rated voltage. The dotted lines CV5 and BV5 give the comparative curves for a unit 19 starting and stopping by application of rated voltage to the clutch and brake windings without overexcitation.

Filed: 1926-07-07
Abstract: 273,103. Pease, E. L. July 7, 1926. Purifier waste, revivefying ; washing processes. -An aqueous suspension of calcium sulphate in presence of carbon dioxide which is employed in extracting ammonia from gases is regenerated by heating e.g. to 80-90‹ C. so as to liberate the ammonia. Coal gas is washed while still hot with hot tar and is passed e.g. at 50-60‹ C. in counter-current to the sulphate slurry which is then withdrawn and heated, preferably under reduced pressure. The liberation of ammonia. may be assisted by passing a current of air or other gas through the heated suspension. Residual ammonia is removed by treatment with an acid substance such as crude phosphoric acid or a solution of mono-ammonium or mono-potassium phosphate or a mixture preferably at a temperature precluding considerable condensation of water vapour. According to the Provisional Specification the order of treatment with phosphoric acid and the sulphate slurry is reversed. The gas is finally treated with cooling water.
