Number	Title	Issue Date
7151359	Variable reluctance generator A variable reluctance generator has phase windings and a bias winding. By controlling the excitation produced by the bias winding, the speed of the machine or the DC link, a power converter using only diodes can supply power to a DC bus. A method of operating a vari...	12/19/2006
4319183	Control windings for self-saturating electrical reactors A self-saturating electrical reactor has a magnetic core located within a casing. A gate winding has at least one turn on the magnetic core and is accessible from outside of the casing. A bundled conductor containing a plurality of individual conductors h...	03/09/1982
4180764	Control circuit for an A.C. discharge lamp A control circuit comprising a series transductor coupled between an A.C. source and an A.C. discharge lamp. The control windings of the series transductor are connected to the A.C. source through a filter, a full-wave rectifier, and a substantially capac...	12/25/1979
4155034	Saturable reactors with feedback A control circuit comprises two series-connected pairs of saturable reactors, the two pairs being connected in parallel between a supply line and a load. Between one pair of reactors are connected two back-to-back diodes, the center tap of which is connec...	05/15/1979
