Abstract: 777,229. Electrolytic production of protective coatings on magnesium and its alloys. UNITED STATES OF AMERICA, SECRETARY OF THE ARMY OF. Jan. 6, 1954, No. 355/54. Class 41. A tough, heat-, abrasion-, and corrosionresistant light brown protective coating of high dielectric strength, typically of thickness 0.5 to 12 mils, is formed electrolytically on a magnesium or magnesium base alloy electrode in an electrolyte consisting of an aqueous solution containing a fluoride, a phosphate, an alkali metal hydroxide, and the product of fusing together the hydroxide and nitrate of an alkali and manganese dioxide, with or without the addition of aluminium oxide. The fusion product is made by heating the powdered alkali metal, preferably potassium, nitrate and hydroxide, and manganese dioxide to 630- 670‹ F., the aluminium oxide, if included, being added as a very fine powder to the fused mixture which is then further heated, and the fused mass after cooling is broken up for use. Typically the electrolytic bath is made up by suction filtering of the powdered fusion product through glass wool, the residue on which is washed with a solution of potassium hydroxides to the filtrate and washings, containing silicates, are added solutions of potassium fluoride and trisodium phosphate. Prior to electrolytic treatment the magnesium or magnesium alloy articles are degreased as with carbon tetrachloride or hot sodium silicate and a detergent, and pickled in a dilute nitric-sulphuric acid solution and are then used as the cell electrodes between which A.C. is passed at a current density of 10-20 amps./sq. ft., the applied potential being not more than 85 volts and the electrolytic bath temperature being 20-30‹ C. The coated articles are rinsed and may then be dipped in 1: 1 aqueous hydrofluoric acid fol. lowed by rinsing and drying. The coatings may be painted or varnished. Specification 777,228 is referred to.

Title: Band-compression device
IPC: G01S7/292
Filed: 1976-01-07
Abstract: 1524271 Bandwidth-compression device THOMSON-CSF 7 Jan 1976 [10 Jan 1975] 00563/76 Heading H4D The frequency bandwidth of signals is compressed by passing them through a variablethreshold amplitude gate to an amplifier and lowpass filter circuit, the filter pass band being narrower than the pass band of the gate. In the Fig. 4 embodiment, for compressing the bandwidth of radar or lidar video signals to be fed to a C.R.T. indicator, the video signals are fed to variablethreshold amplitude-gate 22 which suppresses clutter. The resulting gate output signal is fed to a pulse-stretcher comprising a tapped delay line 23 with its outputs OR-gated by diodes D1-DN and resistor R. The inter-tap delay equals the incoming pulse width. The stretching is equivalent to a bandwidth reduction. Further bandwidth reduction is provided by low-pass active filter/amplifier 24. To achieve a constant false alarm ratio, AGC circuit 25 adjusts the threshold-control voltage supplied to gate 22. Circuit 25 includes in cascade a fixed range gate, an amplifier/limiter and an integrator.

Title: Improvements in and relating to apparatus for producing alternating voltages of peaked wave form
IPC: H02M1/02
Filed: 1942-01-15
Abstract: 554,144. Converting; changing wave form. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 15, 1942, No. 613. Convention date, Jan. 16, 1941. [Class 38 (ii)] Alternating voltages of peaked wave form for application to the ignition electrodes 17 of immersion-ignitor valves 13, 14 are obtained from an A.C. source 20 by means comprising a transformer 28, a capacitor 37 and a saturable inductance 39. The cathodes of the main valves are connected to the junction of oppositely directed rectifiers 42, 43 so that the ignition electrodes of a pair of valves such as those shown which operate with 180 degrees phase displacement alternately receive positive impulses, the negative impulses being suppressed by rectifiers 45, 46. A stabilizing resistance 41 is included effectively in series with the output circuit to ensure that the positive and negative voltage impulses in the common part of the circuit are symmetrical. In the polyphase converter system shown, additional pairs of valves operating with 180 degrees phase displacement are associated with the transformer windings 8, 9, and 7, 11 Equalization of current in the two halves of the system on opposite sides of the interphase transformer 12 is obtained by adjustment of the primary utilization of the inductance 39 by a D.C. winding 40 so as to adjust the phase displacement between positive and negative impulses in the common part of the control circuit. Regulation of the total output of-the converter is effected by phase shift of the input voltage of the transformer 28 either by a rotary phase shifter or by varying the saturation of the inductive element of the phase-shifting network 29, 32, 33 as by saturating windings 34, 35. In a modification, Fig. 2 (not shown), the stabilizing resistance 41 is replaced by resistances connected in series with the reactive elements of the phase shifting network on the input side of the transformer 28, the rectifiers 42, 43 are replaced by an auto-transformer, and inductances are inserted in the leads to the transfer electrodes 18 so as to prolong the period of ionization of the valves and thus increase the possible range of regulation.

[Also in Group XXXVII] In a motor starter apparatus including a switch 17, a contactor 18, and an overload relay 19 serially connected within an hermeticallysealed metal casing 10, the relay winding 19a is shunted by coils 22b, 22c of a variable inductance 22 whereby the proportion of the current flowing through the winding 19a may be adjusted and hence the load in the motor circuit connected to terminals 20, 21 necessary to open the relay contacts 19b, may be varied. The inductance 22 (Figs. 1, 2) comprises a rectangular core 22a surrounding a recess 13a in the casing wall 13 and carrying the series-connected coils 22b, 22c, a permanent magnet 24 extending between opposite sides of the core beneath the recess. The inductance is varied by a second permanent magnet 25 removably secured to the wall 13 by a nut 27 threaded on a stud 26 fixed to the wall. The adjustment is made by turning the magnet 25 through 180 degrees, by inserting non-magnetic spacers between the magnet 25 and the recess 13a, or by exchanging the magnet 25 for another of different size or composition. In a modification the magnet 24 may be omitted. In another arrangement, Fig. 3, the inductance of the core 30 mounted beneath the casing top wall 32 is varied by a permanent magnet 33 movable from and around the stud 34. According to Fig. 5 the core 40 is in two parts 40a, 40d, the part 40d being movable on the stud 43. According to Fig. 7 (not shown) the connections of the coils 30b, 30c of Fig. 3 are modified so that the core 30 functions as a transformer, one of the coils being connected in series with the contacts 19b, and the other coil acting as the transformer secondary being in shunt across the winding 19a.
