摘要： The invention concerns an inductance device formed on the basis of an asymmetrical line. This inductance device includes a plane conductor, preferably cylindrical, a linear conductor extending along and close to the plane conductor and having one end short-circuited with the plane conductor. Positioning devices make it possible to keep the linear conductor in a determined position in relation to the plane conductor. The inductance device is particularly used for the manufacture of power inductances for short waves.

摘要： Disclosed is a reversible inductive energy transfer device for use where efficient transfer of energy between inductors is required. The apparatus is a current amplifying device which utilizes an energy storage inductor which comprises a plurality of series connected induction elements, the inductor being connected in series with a current source and a load inductor. The series connected induction elements are progressively disconnected from the load inductor in a make-before-break manner. The switching may be accomplished by a mechanical switch or by means of superconducting switches, semiconductor switches or PCT switches. The energy storage inductor comprises a single turn or current loop having a plurality of high conductivity, at least partially mutually coupled current paths. The current is continuously or discretely diverted into progressively smaller current paths in order to amplify the current and transfer energy into the load inductor.

摘要： A variable transformer comprising an annular core with a winding which at the end surface of the core is provided with a circular contact path to be connected with a current brush mounted on a rotor (7). The current brush consists of a contact roller journalled on a shaft pin (11) which from the rotor (7) is directed obliquely downwardly towards the end surface of the core and inwardly towards the axis thereof. The contact roller includes a double-curved contact path (17) for punctiform contact with the contact path (18) of the winding. The reactive pressure provided by said contact urges the contact roller upwardly along the shaft pin (11) which where secured to the rotor (7) is provided with a contact plate (14) that is in heat-conducting communication with the rotor (7). The contact plate (14) includes a plane circular surface (15) against which a correspondingly plane, circular surface (15') of the contact roller about the bore (12) thereof abuts. The contact roller is delimited by a conical surface the generatrix of which extends from the periphery of the circular surface (15') to the outer periphery of the contact path (17) of the roller. The rotor (7) is bowl-shaped and its top surface shape corresponds to the internal surface of the upper part of a housing for encasing the transformer.

摘要： A multi-phase regulating transformer is disclosed having a plurality of windings cooperating with stepping trolleys which are driven by a common driving member. To obtain fine adjustment of the output voltage, the trolleys are coupled to the driving member with different plays to introduce a dead travel of the driving member relative to at least one trolley, which exceeds the spacing between two adjoining individual windings of the transformer.

摘要： A continuously variable voltage direct current power supply having first and second output terminals is provided using a variable transformer with a core of magnetically permeable material encircled by at least one electrical winding, with segments of winding turns being exposed along two spaced traverse paths. First and second electrically conductive brushes are simultaneously movable along these respective paths, with at least one brush at all times contacting an exposed segment. Rectifiers connect the first brush to the first output terminal and the second output terminal to said first brush. Rectifiers connect the second brush to the first output terminal and the second output terminal to said second brush. Rectifiers connect a winding terminal to the first output terminal and the second output terminal to said winding terminal. Turn-to-turn short-circuit AC current between the adjoining turns contacted by the brushes is eliminated by employing a transformer winding having a turn-to-turn voltage which is less than the forward turnon voltage through two or more rectifiers. Turn-to-turn current can only flow from one brush to the other through at least two rectifiers plus the resistance of the electrical load. The variable transformer may include both primary and secondary windings or be an autotransformer. Single-phase or multi-phase variable transformers can be used, and advantageous DC power control is effectuated considerably more economically than heretofore, for example, to control the speed of large (multiple Horse Power) DC motors.

摘要： Tap changer voltage regulating apparatus permits a tap changer selector contact to engage an open-circuited new tap without arcing and has a half-tap voltage auxiliary winding which permits halving the voltage being interrupted and doubling the number of steps and also has an auxiliary switch which initially connects the selector contact on the new tap in series with a circulating current-limiting inductor and the load to prevent load circuit interruption and then opens the previous tap circuit so that circulating current is interrupted at reduced voltage and then short circuits the inductor to complete the tap change, whereby the inductor is energized only momentarily.

摘要： A tubular aluminum member is extruded in a rectangular shape and cut to a given length. The four walls of the tubular member are successively cut by a circular saw to form a portion of the tubular member into a generally spiral shape winding with terminal portions at each end. The member is treated to form an insulating layer on the surfaces of the member including the facing sides of the winding to form an inductive winding for passing current. The winding may be compressed and one set of edges treated for engagement by current taps to produce a variable voltage and current device.
