Abstract: The invention is a low-splash dental fluid distribution implement with the ability to evenly wear down tooth decay, diseased tissue, or undesired dentin in oral applications with live patients. The directed multi-beams of pressurized fluid are a combined plurality of individual beams paired in such a manner that the reflected fluid bursts are inwardly directed against each other. This canceling effect prevents damage to the oral tissues of the patient's mouth by curtailing outward bound bursts of fluid arising from the initial directed impact. Also, the outer edges of the strike zone receive a comparable force as that which hits the center.

Abstract: This application relates to the field of music, and more specifically to stepped pitch stringed instruments such as guitars crafted for tone generation to a particular fret spacing arrangement, a particular placement of the bridge, and the use of pitch altering devices for the strings. The preferred embodiment implements a series of frets placed at traditional length ratio spacings for a portion of the neck combined with another series of frets not adhering to the original length ratio. This double series of frets is used in tandem with a micropitch alteration device for the strings. The bridge is crowded closer to the nut than the prior art distance historically producing standard 100 cent intervals between the initial twelve chromatic frets. This crowded bridge is useful for allowing the use of alternate intonation schemes by way of the strings when fretted and sounded.

Abstract: A particular fret and nut morphology for tone generation of stepped pitch stringed instruments such as guitar is described. The use of parallel multi-angle frets having a plurality of angles enables better fingerings for cited alternate six string tunings other than provided by common Barre F tuning; E, A, D, G, B, E. Guitars that employ various alternate tunings are shown to be more practical and efficient with the instant multi-angle fret arrangement than the fingerings available with traditional vertically straight frets. The instant embodiment uses positive torque exclusively for an offset region of the multi-angle fret or nut.

Abstract: This application relates to a cooking spoon or ladle providing improvements designed to prevent the transference of saliva and oral bacteria from a cook to liquid based foods during preparation. This is achieved by the provision of a handle excavated sufficient to allow a sample of the cuisine to flow along the handle from the initial concavity of the stirring end, to a second smaller spoon at the other end of the handle. In the process of departing from the heat source by flowing from the stirring end to the tasting end, the cuisine begins cooling relative to its initial temperature. A simple finger-activated gate can be closed to allow the upper neck to be isolated from the tasting spoon contents.

Abstract: This application relates to various stepped pitch instruments crafted to a novel musical tuning system for the generated frequencies. As such, the tone selection devices are arranged to a distinct set of interval specifications when compared to the tone selection devices for a prior art instrument crafted to sound the common frequencies of 12 tone equal temperament. To generate the bicameral tones, the preferred tuning system utilizes two different series of Pythagorean perfect fifths separated by a known reference interval. Relative to 12 tone, the instant tuning system is primarily concerned both with improving the sour major and minor thirds and perfecting the slightly flat fifths. Substantially fewer tones per octave are used than the number required by standard just intonation. Various modifications to existing prior art instruments are described, as well as a novel enharmonic multitone keyboard.

Abstract: Novel shapes and interrelationships of interreactive domains for wholetone musical selection devices such as keyboards or other user interface medium are described. Chromatic glissandos are allowed on these devices. Operator choice for ascending or descending one finger slurs using any one of the twelve per octave fingerkeys as slur instigator or slur receptor is optimized. Novel one digit multiple pitch slurs numbering three or four pitches are acheived.
