Abstract: A multiple payload cartridge employing circuit components in the squib portion thereof to allow for separate or sequential firing thereof, and hence separate payload ejection, through two-wire connections. Various techniques include the use of a repositionable switch to provide sequential ground connections; the use of mechanical interrupters, e.g., spring-type, crushable-element-type or domed-pop-action type; the use of resistive voltage dividers to permit discrimination in squib firing via applied voltage amplitudes; the use of diodes to permit discrimination in squib firing via applied voltage polarities; and combinations of the above.
Abstract: Each convergence device is particularly adapted for converging the three electron beams of an in-line picture tube. Each convergence device comprises a mounting sleeve having an axial opening for receiving the neck of the picture tube, and a plurality of beam adjusting assemblies mounted around the supporting sleeve. Each beam adjusting assembly may comprise a rotatable supporting ring, a pair of rotatable magnet rings stacked upon the mounting ring, the magnet rings having integral bevel gears facing toward each other, a radial shaft having a bevel pinion meshing with such gears, and a member on the supporting ring and rotatably supporting the shaft. Each magnet ring is formed with permanent magnetic poles. The orientation of the poles can be varied by rotating the entire beam adjusting assembly about the axis of the picture tube. The effective strength of the poles can be adjusted by rotating the shaft, which causes rotation of the magnet rings in opposite directions.

Abstract: This invention relates generally to radio navigation receivers and particularly to multiple frequency phase tracking receivers in which phase information received from a network of transmitters, each radiating coherent signal energy on a plurality of discrete frequencies, is used for navigation or position determination. There is provided a method of updating positional information derived from the plurality of discrete frequency signals by cross-coupling the input to each of the discrete frequency receivers so as to reduce the lag time between receiving two sequential one-frequency signals and updating the signal.
