Abstract: A decorative amusement device includes a transparent sphere that is mounted on and that cooperates with a base to confine a water receiving space to be filled with water. A drive unit is mounted inside the base, and has a rotary drive shaft extending through the base into the water receiving space, and a water agitator mounted on the drive shaft inside the water receiving space. A decorative member is mounted on the base inside the water receiving space, and includes a prop, a rotary vane mounted rotatably on the prop, and a guide member disposed around the water agitator so as to guide the water that was agitated by the water agitator toward the rotary vane to result in rotation of the rotary vane inside the water receiving space when the drive shaft rotates.

Abstract: A digital switching system is described for providing time division multiplexed digital communication of parallel sequential signals of N words each of M bit length between N telephone data subscribers over N transmission lines in which an array of orthogonal RAM memory devices provide parallel-to-serial conversion and multiplexing of the N words each of M bit length to provide a time division multiplexed serial digital bit stream of M words, each N bits in length, which are transmitted over a transmission line to a serial-to-parallel converter and coupled to a second orthogonal RAM memory device in which the N words M bits in length from the serial-to-parallel converter are stored and coupled to N telephone data subscribers over the transmission lines.

Abstract: A circuit for detecting a failed diode in a multiple diode rectifier bridge detects open or shorted diodes in both multi-phase, half-wave rectification and single or multi-phase full wave rectification arrangements and provides a failure signal for sounding an alarm or tripping the circuit to protect the load or power source as the case may be.
