Built-in Toothpaste. A toothbrush with dentifrice-coated nylon bristles was announced by Buffalo's Disposable Tooth Brush, Inc.

Price: 15-c-.

Dust Must. A home air purifier that uses static electricity to attract and trap pollen, dust and smoke particles was brought out by Raytheon Mfg. Co. of Waltham, Mass. Modeled after Raytheon's static machines that sterilize medical laboratories, the Micronaire room cleaner sucks air in with a fan and passes it over electrically charged metal plates to which dust clings. Purifier requires no installation, rolls on casters and plugs into a standard outlet. Price: $229.

Concerts by the Yard. Hi-fi music on magnetic tape was put on sale by Webster-Chicago Corp. Sales of such tapes have been small because reels could only be recorded a few at a time.
