Abstract: This invention is directed to an air freshener composition containing a fiber pad comprising at least one needle-punched, nonwoven, hydrophilic fiber wherein the fiber has a capillary structure and deep grooves or channels along the longitudinal axis of the fiber, a fragrance incorporated into said fiber pad, wherein the fiber pad is enclosed by a container having air passageways to allow for the fragrance to escape into the surrounding environment.

Abstract: An improved process is described for producing glass in which a glass batch is mixed with a binder, aged, compacted, and compressed into briquettes, which are heated to partially react the contents of the batch in a prereaction stage. Prereacted briquettes are then placed in a fuel-fired furnace and heated at a temperature not above 2,600.degree. F (1,430.degree. C) to refine them into glass.

Abstract: An indicating system for a radio receiver is formed of an indicator and associated control circuitry. The indicator is comprised of two emitting diodes wired in parallel and in reverse polarity, and encapsulated in a translucent package. Each diode in an indicator emits light of a visibly distinct wavelength when energized. The control circuitry causes a change in polarity of bias voltage applied to the indicator, and, in so doing a change in color of the indicator. With appropriate control circuitry, the color of the indicator indicates whether the receiver is tuned to an AM or FM station, or whether the station is broadcasting in mono or stereo. The indicator can be mounted to the dial pointer causing a change in pointer color with a change in receiver function. Additionally, the amount of current through the light emitting diodes and thus the intensity of emitted light may be varied in accordance with a parameter variation as, for example, accuracy of receiver tuning.
