Title: New or Improved Process for the Manufacture of Pure Ammonium Nitrate.
IPC: C01C1/18
Filed: 1909-09-13
Granted: 1910-08-25
Abstract: 20,907. Nydegger, O., and Wedekind & Co., R. Sept. 13. Ammonium nitrate.-In making ammonium nitrate by double decomposition between ammonium sulphate and calcium nitrate, an excess of calcium (or barium or strontium) nitrate is employed, whereby, after filtration and evaporation, crystals of ammonium nitrate free from magnesium nitrate are obtained. The mother liquor is again used for obtaining an excess of alkaline-earth nitrate, and this series of operations may be repeated until the magnesium salts accumulate to top great an extent. To remove the magnesium salts, an excess of ammonium sulphate is added, alkaline-earth sulphates, and double ammonium alkaline-earth sulphates being precipitated. To the solution thus purified excess of calcium, barium, or strontium nitrate is then added for use again. Specification 19,465/06 is referred to.

Title: Improvements in and connected with Electrically Driven Centrifugal Drying Machines.
Inventor: MACFARLANE WILLIAM ALLAN
IPC: H02P1/54

Granted: 1910-11-15
Abstract: 26,406. Macfarlane, W. A. Nov. 15. [Cognate Application, 5178/10.] Protective arrangements.- In an installation of electrically - driven centrifugal machines, arrangements are provided whereby not more than a certain number of machines can be accelerated at the same time, thus reducing the maximum load on the generator. The invention is analogous to that described in connexion with hydraulically driven machines in Specification 20,177/07, [Class 23, Centrifugal drying &c.]. Specification 612/02, [Class 23, Centrifugal drying &c.], is also referred to. An electrical means for producing the required control is shown in Fig. 2. In connexion with the switch A of each machine of the installation is arranged an electromagnet or solenoid B traversed by the whole or a fixed fraction of the current supplied by the generator. To the core of the solenoid is connected a lever E bearing a detent C, which engages with a spring pawlR on the handle of the switch A, so that the current can be switched off from the corresponding centrifugal machine at any time, but only switched on when the current supplied by the generator does not exceed a certain amount. Instead of each machine being fitted with a solenoid, there may be a single solenoid operating a rocking bar carrying detents connected with all the switches. The solenoid, instead of operating the detents directly, may operate a relay. Fig. 6 shows means for operating the detents mechanically. To each centrifugal machine is connected a governor Z connected by a lever Z<1> to a detent X engaging with spring pawls carried by sliding rods Q, Q<1>, Q<2> connected by links to the handles of the switches A. The fulcrum d of the lever Z<1> is carried by an eccentric Y on the spindle of the switch, so that, when the current is off, the detent X is always clear of the pawls on the bars Q, Q<1>, Q<2>, but, when the switch is on, the detent X engages with the pawls until the governor Z attains its full speed.

Title: Improvements in Rotary Transformers for Converting Alternating into Direct Current.
Inventor: AUVERT LOUIS RENE
IPC: H02M1/22
Filed: 1910-09-08
Granted: 1911-09-08
Abstract: 20,948. Auvert, L. R., and Ferrand, A. F. E. Sept. 8. Rotary converters.-The direct-current voltage of rotary converters, which is regulated by shifting the brushes, is maintained approximately constant at any particular value, in spite of the oscillations of the synchronous motors driving them, by providing the converters with an even number of commutators and so connecting their brushes in series that the voltage variation in one set of brushes is counteracted by the voltage variation in the other set of brushes. Fig. 3 shows the application of the invention to a single converter provided with two commutators c<1>, c<2>, the brush-holders d<1>, d<2> being geared together through differential gearing e. It is also necessary in the case of two separate converters driven by a single motor to connect the brushes in series and rotate them in opposite directions. In the application of the invention to a number of converters driven by separate motors and connected to a single generator, the converters may be divided into two sets, and those of one set rotated in the opposite direction to those of the other set; or all the converters may be rotated in the same direction and the commutators divided into two sets and the brushes of one set rotated in the opposite direction to those of the other set. In order that the synchronous motors may all oscillate in the same direction and to the same extent, they may be geared together, or corresponding points may be taken on each rotor forming a three-phase or other polyphase system and connected together through slip-rings b<2>, b<3>, b<4>, Fig. 5.
