Title: "method for the electrical insulation of the surface of metallic sheets for laminated magnetic cores"
IPC: H01F41/02
Filed: 1953-12-02
Abstract: In a method of producing a thin electrically insulating coating on metallic sheets for laminated magnetic cores a solution of one or more salts selected from magnesium, nickel, zinc, copper and chromium salts which will produce free oxygen and a divalent or trivalent oxide when heated, is applied to the surface of the metallic sheet and then dried, so that a continuous crystal layer is obtained, which by a subsequent heating is disintegrated, so that the oxygen liberated from the salt reacts with the surface of the metallic sheet to form a divalent or trivalent oxide, the divalent oxide thus formed combining with the trivalent oxide formed from the disintegrated salt or salt mixture, or the trivalent oxide thus formed combining with the divalent oxide formed from the disintegrated salt or salt mixture, in order that a coating of a spinellike chemical compound shall be formed on the surface of the metallic sheet.  A solution of a nitrate to which has been added a small amount of an organic salt, e.g. magnesium acetate or formate, is preferably used; the solvent may be water or ethyl alcohol.  The method may be combined with the usual annealing process for the sheets of laminated magnetic cores. In this case the sheets are immersed in the salt solution and then removed and heated, so that the salt will be dried to form a continuous crystal layer, the salt layer then being disintegrated by the succeeding heating to a high temperature, the desired layer subsequently being formed at the still higher temperature at which annealing takes place.  By way of example is described the formation of a spinel-like compound, composed of ferric oxide and magnesium oxide, on iron sheets, by immersion for 5 secs. in an aqueous solution of magnesium nitrate and magnesium acetate, drying at 200 DEG C., and annealing for 5 minutes at 800 DEG C.

Abstract: 1500406 Transistor switching circuits DAINI SEIKOSHA KK 13 Aug 1975 [14 Aug 1974 (2) 23 Aug 1974 29 Aug 1974 2 Sept 1974 (2)] 33735/75 Heading H3T [Also in Division G3] An anticontact bounce circuit comprises a bistable which memorizes the switched condition of the input and which is reset by a reset pulse, the output being fed to a further circuit from which a bouncefree output is obtained, the further circuit being clocked in synchronism with the reset signal. In a first embodiment, Fig. 1, closure of the mechanical switch S2 coupled to inverter 1 sets bistable FF which then remains set until reset by a pulse R2. The output of the bi-stable circuit is coupled to the input of a second bi-stable circuit 5 via an input gate G1 which is alternately clocked on and off by clock signals #, #, the pulses R2 occurring during periods when gate G1 is closed. A second gate G2 is arranged to be on during the periods when G1 is off and vice versa. If bi-stable FF is set by closure of the switch S2 then, during a subsequent clock period when G1 is open, the "1" level at its output will set bi-stable 5 to produce a "1" level and the output of the circuit. After switch S2 is opened again bi-stable FF will be reset by the next following reset pulse to give a "0" output. During the next period when gate G 1 is open this will be fed to bi-stable 5 to reset it and produce a "0" at the circuit output. Modified input circuits are described in which the inverter 1 forms a part of the first bi-stable, Figs. 4, 6 (not shown) and circuits for deriving the clock and reset pulses are also described, Figs. 4, 6, 8 (not shown). The last mentioned also discloses a modification of the input inverter.
