Abstract: 414,939. Electrodeposition of chromium. SCHLOTTER, M., 133, Alte Jakobstrasse, Berlin. Nov. 22, 1933, No. 32664. [Class 41.] A chromium anode is employed and an alternating current is superposed on the plating current to induce solution of the anode. A solution of a chromium salt is employed as electrolyte ; by the employment of alternating current of suitable frequency the chromium goes into solution as a salt and not as chromic acid. A suitable electrolyte consists of 280 gms. of chromic chloride and 20 gms. of boric acid to 1 litre of water at a temperature of 22‹ C. Conducting salts such as those of alkali or alkaline earth metals may be added. Thiocyanates may also be added. The directcurrent source is connected to the electrodes through a choke, and the alternating current source through a condenser. In the apparatus shown, alternating current is superimposed at the anode A only by means of a transformer T, the secondary circuit of which is completed through an auxiliary electrode H. In a modification, alternating currents of different frequencies are superimposed at the anode and cathode. Reference has been directed by the Comptroller to Specification, 274,913, [Class 41].

Abstract: 1,119,877. Protective systems for superconducting apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 June, 1967 [25 July, 1966], No. 33365/66. Heading H2H. In order to limit the current which can be supplied by a transformer 4, the windings of which are of a superconducting material, the secondary winding 3 of the transformer is connected to output terminals T3, T4 by way of a circuit comprising a reactor 6 and a capacitor 7 which is shunted by a saturable type reactor 8 and resistor 9. Thus at normal values of output current from the transformer, the reactor 8 is unsaturated so that the reactor 6 and capacitor 7 resonate to form a low impedance but at abnormal values of current the reactor 8 saturates to upset the resonance, whereupon the LC circuit 6, 7 form a high impedance. If desired, the reactor 6 can also be made of superconducting material and placed in the Dewar vessel 5 with the transformer. In a second embodiment the reactor 6 is omitted and the reactive part of the LC circuit is formed by the transformer.

Filed: 1958-10-21
Abstract: 868,620. Interrupters. ALKAN & SINAY. Oct. 21, 1958 [Oct. 22, 1957], No. 33515/58. Class 38 (5). A device for cyclically controlling a two-position switch by the axial movement of a rotary cam, comprises an electric motor 2 which drives, through reduction gearing 7, a toothed wheel 8 and its hub 9 rotatable on a fixed spindle 3. This movement is transmitted to a cam 14 and its hub 15 by parallel rods 12, 13, which engage a roller 11 secured to the hub 9, a second roller 25 being secured to the hub 15. Members 14, 15 are urged axially by a spring 16 towards a normally-fixed disc 26, which carries a ramplike projecting cone 29 and is rotatably adjustable by a knob 32 through a pinion 31 and a toothed ring 30. In operation a mercury switch 23 is held closed, by engagement of the beak 21 of a rocker 22 with the cam surface 17, until roller 25 engages cone 29, whereupon the cam 14 is moved towards the wheel 8 to allow the rocker 22 to drop and open switch 23. The side of the beak 21 then slides on the cam face 18 until it is engaged by a radial slot 19, whose face 20, on further rotation of the cam, lifts the beak 21 back to its original position so closing the switch. The ratio of the switch-closed to the switch-open period during each complete rotation of the cam 14 can thus be varied by adjustment of the disc 26, the duration of the cycle being determined by the speed of the motor 2. Fig. 2 shows a three-phase switching arrangement which embodies the above features and which maintains the angular shift of the closing and opening switch movements between each phase at 120 degrees or other predetermined angle. Switches 64, 65, 66 are controlled by cams 50, 51, 52, coupled to sleeves 47, 48, 49, adjustably secured to a shaft 43 which is driven by a motor 42 and toothed wheel 46. The cams are urged against discs 53, 54, 55, which are simultaneously adjustable by pinions 56, 57 58, fixed on a shaft 45, a graduated drum 60 enabling the desired setting to be made. The mercury switch 23 may be maintained temporarily open or closed by a mechanism which moves the rocker 22 in the axial direction with respect to the rotary cam 14.
