Abstract: A point of use water purification system for home use is provided comprising a carbon block filter housed in a self-contained disposable pressure vessel for removing particulates and organic contaminants from water. The filter is provided with a pore-size distribution, a binder and a flow path which optimizes filtration performance and enhances microbiological kill rates obtained in a source of radiant energy which is used to kill microorganisms in the filtered water. The source of radiant energy comprises an ultraviolet discharge lamp having an elongate central axis and a diverter for providing a spiral plug flow of water about the discharge lamp. A flow regulator adjusts flow through the system for varying line pressure conditions to ensure adequate exposure of microorganisms to ultraviolet energy. A lamp control circuit conserves power and optimizes ultraviolet output.

Abstract: Most of the circuitry of an electronic organ is made up of a plurality of digital large scale integrated (LSI) circuit chips. Certain of the chips can be duplicated or substituted for others of like type to provide an organ with more or less tone generators, more or less features, etc., whereby organs of various price levels can be constructed from the same basic parts. In operation, essentially all of the organ functions and features are provided by carrying out logical and arithmetic operations on digital pulse trains generated under control of a master clock.

Abstract: In an electronic organ or the like constructed of a plurality of large scale integrated circuit (LSI) chips, the present disclosure relates to a master control LSI chip having a counter providing multiplexing drive outputs and also having a read only memory (ROM) programmed to provide rhythm voice patterns.

Abstract: In a modular, expandable organ system comprising a plurality of large scale integrated circuit (LSI) chips an LSI chip is provided which produces frequencies corresponding to notes played on an organ keyboard. Outputs of different duty cycles of rectangular waves are provided for best simulating desired sounds. Other outputs are provided in which the notes are in octave groups facilitating filtering thereof. Each group of outputs has different attack and decay characteristics respectively under the control of the organist so that similar or different types of attack and decay may be provided on different outputs.The present LSI chip provides three generators on one chip. The chips are capable of being interconnected such that any multiple of three generators may be provided.
