Title: Process for the production of ferrites
Inventor: HUND FRANZ
IPC: H01F1/36
Filed: 1959-01-22
Abstract: Ferrites are prepared by treating an aqueous solution of di-valent iron salts and salts of another desired di-valent metal component of the ferrite, with less than the stoichiometric amount of an alkaline precipitant and thereafter adding an iron alloy containing iron and the other metal of the ferrite, together with an oxidizing agent and thereafter washing, drying and heating the precipitate to a temperature below 1200 DEG C. in the presence of an oxygen-containing gas.  Suitable di-valent metals other than iron are nickel, zinc, copper, manganese, cobalt, cadmium and magnesium.  These and the iron may be employed in the form of sulphates, chlorides or nitrates.  If more than one metallic constituent (other than iron) is employed, only one need be alloyed to the iron and the other added in metallic form.  As oxidation agents there are employed oxygen, air, aromatic nitro compounds, in particular nitro benzene, chlorine, chlorates, perchlorates, permanganates, chromates and dichromates. According to Examples (1) a solution containing ferrous and cobaltous chlorides, was treated with sodium hydroxide solution and the precipitate so obtained was oxidized by the introduction of air.  Thereafter iron/cobalt alloy fillings were added whilst continuing to pass in air, whereby after four days, a coloured hydrated ferric oxide containing 3% of cobalt oxide was obtained. By heating at 250 DEG C. a ferro-magnetic cobaltcontaining gamma Fe2O3 spinel was obtained. (2) A mixture of iron and nickel sulphates was treated with sodium hydroxide solution and iron-nickel alloy and nitrobenzene were added thereto incrementally.  The precipitate was dried at a 100 DEG C. and was calcined at 1100 DEG C to form a nickel/iron spinel.  (3) Iron, nickel and zinc sulphate solutions were treated with sodium hydroxide solution and ironnickel filings together with zinc filings were added thereto with nitrobenzene.  After the reduction had occurred the aniline was separated off and the precipitate washed and dried at 100 DEG C., and calcined at 800 of 1100 DEG C.

Title: Improvements in high voltage direct current power supply systems
IPC: G05F1/52
Filed: 1946-01-25
Abstract: 719,690. Automatic voltage control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 25, 1946 [Jan. 30, 1945], No. 2499/46. Class 38(4) In a series valve type automatic regulating system for high voltage D.C., the difference between voltages derived from the regulated voltage and a reference voltage is applied to the control electrode of the series valve through two D.C. amplifying stages in cascade, the anode supply to' the first amplifying stage being the reference voltage. A fullwave valve rectifier 9, the A.C. input to which may be adjusted by tap changer or induction regulator (not shown), supplies a variable load 1 with a high D.C. voltage which is automatically controlled by a series triode 16. A voltage dependent on load voltage is obtained across a resistor 24 and applied, in opposition to an adjustable reference voltage obtained across the lower portion of potentiometer 63, potentiometer 64 and resistor 65, to the grid-cathode circuit of a pentode 70 which forms with a tetrode 71 a two-stage direct-coupled amplifier controlling triode 16 to maintain the load voltage constant. The voltage from which the reference voltage is obtained is derived from A.C. mains 30, through a full-wave valve rectifier 32 and series tetrode 38, and developed across busbars 28, 29. This voltage is maintained constant by feeding a portion of it, obtained across a resistor 50, to the gridcathode circuit of a pentode 43 constituting a direct - coupled amplifier controlling tetrode 38. Glow discharge tubes 51 and 52 stabilize the cathode potential of pentode 43. The voltage between busbars 28, 29 also provides anode and screen supplies for tetrode 70, the screen voltage of which is controlled by glow discharge tube 80 to protect the valve under short-circuit load conditions and to provide a desirable voltage overshoot following such conditions. A diode 23 and spark gap 21 prevent excessive grid-cathode voltage on valve 16 under short-circuit load conditions. A fullwave valve rectifier 97 provides anode and screen supplies for tetrode 71. A choke 84 and certain condensers provided to obtain the desired control under transient conditions are referred to.

Filed: 1923-01-29
Abstract: 213,051. Raettig, B. Jan. 29, 1923. Two-part couplings combined with electric switches. In an electric switch combined with plug and socket contacts, the opening in the casing d, Fig. 1, to receive the plug g is closed at its inner end by a fixed plate l for preventing access through the opening to the movable contacts a of the switch when they are in the "off" position and the plug is withdrawn. The plate l is provided with slots m through which the contacts a move to engage the contacts e mounted upon insulation f in the plug g. The switch-blades a are pivoted on an insulated plate c and are operated by an exterior lever h through quick-break mechanism comprising bows n loose on the pivot axle of the knives and connected to the knives by springs m<1>. A frame i connected to the lever h and extending in front of the opening prevents insertion or withdrawal of the plug when the switch is in the "on" position. In a modification, shown in Figs. 4, 6 and 7, the switch is prevented from being moved to the "on" position before the plug is inserted. The axle 4 of the lever h carries a cam portion 13 which is prevented from moving by engagement with a member 14 pivoted upon a bolt 16. When the plug is inserted in the casing a nose on the side thereof engages an extension 17 of the member 14 and turns the latter about its pivot against the action of a spring thereby freeing the cam portion 13 and allowing the switch to move to the "on" position. In this modification the plug is prevented from withdrawal when the switch is "on'' by a cam 7 on the axle 4 turning to press outwardly a. pin 8, which engages a nose 9 on a lid 10 for covering the opening and presses the lid downwards so that a part 11 of it engages a projection 12 on the plug g.
