Abstract: AN ULTRAVIOLET RADIATION DETECTOR     ABSTRACT     A semiconductor body is used by the present invention in the detection of ultraviolet radiation.  An antireflection layer is on a portion of a surface of said body with electrical contacting means on the remaining portion of the body.  A phosphor layer is on the antireflec-tion layer.  The phosphor layer is capable of converting the ultraviolet radiation into visible or near infrared radiation which can be detected by the semiconductor body.          On the phosphor layer is a metallic film which is substantially transmissive to ultraviolet radiation and substantially reflective to visible or near infrared radiation.  The converted radiation in the phosphor layer which strikes the metallic film may therefore be directed toward the semi-conductor body for detection.

Abstract: ABSTRACT OF THE DISCLOSURE            A circuit interrupter is provided for an electrical capacitor, wherein an increase in internal pressure causes bulging of the capacitor cover, which is used to break internal electrical connections. Each of a pair of spaced terminals mounted on the cover has an electrical stud projecting through an aperture in an insulating bridge member positioned under the cover and spanning a pair of indentations in the cover.          Connection tabs from a capacitor section project upwardly and are welded to the terminal studs at the underside of the bridge member in such a manner that the tabs can not pass through the apertures. When the cover bulges upward because of an internal pressure increase, the terminals move upward and become spaced from and slightly rotated with respect to the capacitor section. Also, the connections of the tabs to the terminal studs cause the bulging cover to flex the bridge member upward. The stresses in the weld connections are greatly increased because of both the upward movement of the terminals and the rotation of the terminals.          At a predetermined increase in pressure the combined tension and rotation stresses in the welds cause both welds to rupture, and the bridge member springs back into essentially a level position.          At this level position the tabs and the studs are kept well separated to prevent remake of the circuit or striking of an arc at a broken connection.

Abstract: ABSTRACT OF THE DISCLOSURE   A plastic container has a neck formed with a substantially horizontal flat top.  On the inside of the neck proceeding down-wardly there is a substantially vertical first sealing surface, then a top groove, then a very smooth second sealing surface of less diameter than the first sealing surface terminating in a lower groove and then a vertical stretch which merges into a breast which widens out to the full size of the container.  On the outside of the neck proceeding downward from the flat top is a first vertical surface terminating in a horizontal inwardly extending shoulder below the elevation of the top groove, then an indented second vertical surface of lesser diameter than the first vertical surface and then an external bead having an out-ward-downward slanted top surface and a bottom horizontal inward-directed second shoulder at about the level of the lower groove, then a third vertical surface at about the level of the vertical stretch.  The container is blow-molded or injection molded and, except at the top of the neck, where it is thicker, has a sub-stantially uniform wall thickness. However, the second sealing surface has an "injection finish" obtained by use of a blow-pin in the mold.  The cap is an improvement on that shown in U. S.          Patent No. 3,338,446.  The lower internal bead (which seat under the second shoulder of the neck) is interrupted in a plurality of gaps, permitting stretching of the cap to seat on the neck.  Fur-ther, there are thickenings on the  interior of the cap outer skirt paralleling the spiral groove of the skirt from the bottom edge of the skirt to the horizontal groove to facilitate tearing the skirt when the tab is pulled.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved system for sounding notes in sequence is disclosed for use in an electronic organ having a set of tone signal genera-tors, a set of key operated switches actuated by the keys of a keyboard, an acoustic output system and a set of keying circuits connected between the output system and respective ones of the tone generator.  The improved system uses a counter for producing in time sequential order a set of two component pairs of logic signals in response to the operation of one or more of the keyed operated switches.  Each pair of logic signals corresponds to a different one of the tone generators.  A decoder means for receiving and decoding pairs of logic signals is provided and causes the keying circuits to transmit a corresponding tone signal to the output system as a corresponding pair of logic signals is received for each tone generator, for which a corres-ponding key switch has been actuated.  This system also uses control means for stopping the counting means for a predetermined time each time a tone signal is transmitted to the output system, so that a sequence of tones is sounded at equal time intervals. This system permits an improved digital arpeggio system for an electronic organ which, through digital logic techniques, permits a wide variety of modes of operation, including arpeggio mode, strum mode, normal mode, three different note patterns, as well four mode modifications including continuous mode, multi-tone mode, reverse mode and touch strip mode.
