摘要： An electronic bass musical instrument that has the appearance, character and ambiance of a traditional washtub bass where the sounds of the bass are produced electronically by manually pressing an electrically conductive string extending along a neck of the bass against selected electrically conductive contacts arranged at spaced positions along the neck thus sending signals to an electronic control circuit of the instrument, whereby the sounds of the bass are produced electronically, providing vastly improved tonal quality and pitch accuracy to the sounds produced.

摘要： A model railroad car magnetic coupling and uncoupling system employs pairs of cooperating magnetic couplers that have unique and simplified constructions, and an uncoupler mechanism that is mounted beneath a section of model railroad track and operates automatically to separate the mechanical couplers of two adjacent model railroad cars positioned on the section of track.
