Abstract: An optical metronome using sheets of music of non-sagging sheets of translucent material with notes spaced according to their value and vertically aligned measures on a display panel of light columns formed of vertical bars of triangular cross-section in white reflectors with an angular air gap and a light source for each bar. Circuitry coordinates sequential lighting of the bars in proper musical tempo and properly placed downbeat and is also attached or attachable to electronic organ circuitry or stands alone with automatic turn-off of lights to the bars if organ not counting.

Abstract: A unit is provided for accommodating various disposable articles, such as used surgical blades and the like, wherein each article is automatically removed from the tang of a handle and retained within a receptacle. The removal of the article from the tang is accomplished without physical contact between the article and the person utilizing the unit. The receptacle is provided with at least one elongated article-accommodating compartment accessible only through an entry formed at an end thereof. The entry is sized so as to permit the tang and attached article to be manually inserted therethrough into the compartment. Upon the tang being withdrawn from the compartment through the entry the article is automatically removed therefrom and remains entrapped within the compartment.

Abstract: A thin sheet metal orifice plate is disclosed having at least one orifice therethrough with a rounded inlet to improve flow and an outlet defined by an encircling projection whose axis accurately conforms to a predetermined direction. Apparatus for the production of such an orifice plate is disclosed and includes a forming tool operable to form a spherical boss in a flat intermittently advanced thin metal sheet of orifice blank material. The apparatus includes an orifice plate blank trimming tool having a punch and die assembly for accurately trimming the spherical boss from a continuous strip such that an annular flange is provided therearound. An orifice punching apparatus is provided having a chuck for holding an orifice plate blank adjacent to a resilient backing material. The chuck is supported by an angular adjustment apparatus which, in turn, is rotatably supported on a base and provided with a pair of detent mechanisms. The detent mechanisms secure the angular position of the adjustment apparatus.

Abstract: A liquid atomizing method and apparatus including a conduit member having an annular ring eccentrically mounted thereon such that a radial port in the ring is aligned with a radial aperture in the conduit member. A thin flexible orifice ribbon is intercalated between the ring and the conduit member. In one embodiment of the invention, a vibratory device is rigidly mounted upon the exterior surface of the conduit member and functions to induce the formation of uniform droplets within fluid flowing through apertures in the orifice ribbon. In another embodiment of the invention an elongate flexible orifice ribbon, having a plurality of spaced orifice zones, may be mounted upon an advancement mechanism to facilitate maintenance of a clean unobstructed set of apertures in communication with the conduit port. The atomizing apparatus is readily serviceable without special tools.
