Title: Magnetic switch assembly
IPC: H03K17/80
Filed: 1954-05-12
Abstract: 749,346. Circuits employing bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. May 12, 1954 [May 26, 1953], No. 13972/54. Class 40 (4). In a magnetic switching arrangement in which the polarity of a single core in a matrix of saturable cores may be changed by selectively and simultaneously energizing a column and a row winding, each winding comprises a single coil which links with all the cores in the associated column or row of the matrix. The arrangement is stated to substantially reduce the interturn and inter-winding capacitances which, in the prior arrangement of separate coils on each core connected in series to form the column or row windings, cause the induced output pulse produced by the selected core to have a variable length and time lag according to the position of the core in the matrix. The basic winding arrangement is shown in Fig. 1A in which toroidal cores 20 which carry separate output coils 28 and may have a substantially rectangular hysteresis characteristic are linked by a single column coil 22, the inter-turn and inter-wiriding capacitances being represented at 32 and 30 respectively. The switch may be arranged within a square or rhombic frame 46 of insulating material, Figs. 2 and 4, the row and column coils 56 being wound tightly between two pairs of bakelite rods 50. A toroid core 20 is suspended at each point of crossing of two coils, the spacing between the adjacent coil sides 58, 60 passing through the core being equal to its internal diameter. The coils are terminated at terminals 62 mounted on the sides of the frame, while the output coils 64 are connected between terminals 54 on an insulated top plate 52 and a mesh of bus wires or a metal common return plate (not shown). The angular crossing of the coils and maximum spacing reduces interwinding capacitance to a minimum. The cores may alternatively be composed of common ferro-magnetic materials having low retentivity and coercive force, and in this case the use of a bias winding 68 is necessary. This winding is common to all the cores and is positioned in each core intermediate the adjacent column and row coil sides. Due to the constant bias potential the winding further reduces inter-winding capacitance by acting as an electrostatic screen. In a second embodiment, Fig. 7, the column and row coils 78 are positioned between bosses 76, 74 located on opposite sides of an insulated plate 70 having a cut-out window 72 and terminals 82. Toroidal cores having an internal diameter equal to the thickness of the plate are suspended between the coil sides at their crossing-points. In the arrangement shown, two cores linked by a common output winding are arranged at each column-row crossing.
