Abstract: A method and apparatus for determining the composition of glass, and for sorting glass according to composition. Glass of unknown composition is irradiated and an x-ray fluorescence spectrum is detected from the glass. The detected x-ray fluorescence spectrum is then compared with a plurality of fluorescence spectra corresponding to glasses of known composition. The glass of unknown composition is then determined to correspond in composition to the glass of known composition having an x-ray fluorescence spectrum most closely matching the spectrum detected from the glass of unknown composition. The glass may then be sorted according to determined composition. In operation, a substantially continuous stream of glass pieces is irradiated and detected while the stream is moving. Once the composition of a piece of glass in the stream is determined, it is diverted into an appropriate container of like compositioned glass.

Abstract: In a video-type computer system and the like, an improved memory circuit is provided for adapting the system to CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accommodate any CRT screen sought to be used, and also a serial shift register having taps at a plurality of different locations corresponding to different columns of cells in the RAM unit. When the RAM unit is in serial mode, a row of data is transferred into the serial shift register. Then the column address applied to the RAM unit is used to instruct and actuate a suitable decoder circuit to select the tap appropriate to unload the portion of the serial shift register containing the data bits of interest.
