专利汇可以提供Numeral base conversion instructional device专利检索,专利查询,专利分析的服务。并且The instant invention involves a conversion device which enables the ready conversion of numerals in a first numeral base, such as the base 10, or decimal system, to another and different, numeral base system, such as the base 2, or binary system. The conversion device generally comprises a container divided into an upper section, a midsection and a lower section. The upper section serves as a reservoir for discrete measuring units, such as balls. The midsection serves as an area of transfer for the balls between the reservoir and the lower section. The lower section consists of a plurality of parallel channels, each adapted to receive a preselected number of balls. A selector bar, moveable along the lower section, has means for defining the number of balls which can be contained in each column. The device is operated by a gravity feed. If a predetermined number of balls is released from the reservoir into the midsection, and selectively directed to the lower section, the balls will fill up varying numbers of the columns, depending upon the location of the selector bar. By observing this number of columns filled up by the balls, one can readily determine the corresponding numeral in a particular base system. The corresponding numeral in a different base system for the same amount of balls can readily be determined by moving the balls from the columns back into the midsection, relocating the selector bar again allowing the columns to fill up with balls, and then noting the number of filled columns.,下面是Numeral base conversion instructional device专利的具体信息内容。
