Abstract: A liquid powered assembly including a housing; a removable bottom base; a seal; an electrolyte battery assembly; and, a liquid powered device is described. The housing includes an upper end portion and a lower end portion. The housing has a volume for containing an electrolyte solution. The lower end portion has a fluid inlet. The removable bottom base has a bottom surface for supporting the liquid powered assembly. A seal engages the housing and the removable bottom base to help contain the liquid. An electrolyte battery assembly is positioned within the housing. A liquid powered device is operably attached to the electrolyte battery assembly. To function, the housing and the removable bottom base are detached relative to each other and the housing is turned substantially upside down to allow filling of the housing via the inlet. The bottom base is then attached to the housing and the assembly is then inverted for use.

Abstract: An improved rim for a mouthpiece for a plurality of non-French horn labrosone brass musical instruments. The improved rim has a rim width having a predetermined width measurement as a smallest width dimension taken of an outer edge, a crown, and an inner edge of the improved rim, where the rim width can be a same width as a playing surface of the improved rim, where the playing surface is a width of the improved rim engaged by a musician's lips. Also provided are improved rims removably or permanently affixed to the mouthpiece.

Abstract: A musical instrument tuning device includes a tuning sleeve and a tuning collar threadingly engaged to the tuning sleeve. The apparatus is mountable onto a first portion of a musical instrument which also has a second portion, the second portion being slidingly adjustable relative to the first portion to change the length of an air passage to tune that musical instrument. In one embodiment, the musical instrument tuning device is mounted on a neck portion of a saxophone to which a mouthpiece is typically engaged. Rotation of the tuning collar moves a saxophone mouthpiece relative to the neck portion and thereby enables a musician to quickly and precisely tune the saxophone.

Abstract: An animal call includes a mouthpiece, a barrel, and a reed. The mouthpiece defines an air channel therein and has a reed bed proximate the air channel. The barrel is coupled to the mouthpiece and has an internal chamber that is fluidically coupled to the air channel of the mouthpiece. A surface comprising the air channel varies in order to maintain a substantially constant cross-sectional area magnitude along a length of the channel. The reed is disposed adjacent the air channel and proximate the reed bed.

Abstract: A protective cover for the mouthpiece of brass instruments is formed by three portions. The first cover portion is in the form of a molded tube or cylinder. The tube is sized to snugly fit over the cup of the mouthpiece and a part of the instrument shaft adjacent the cup of the mouthpiece. The second cover portion is a cup formed from a second tube or cylinder having one closed end. The cup is sized to be snugly mounted over the rim of the mouthpiece and an adjacent part of the first cover portion covering the cup of the mouthpiece. The first and second portions are molded from an elastomeric thermal insulating foam material and covered with a stretchable nylon shell. The third portion is in the form of an elastic band connected at one end to the first portion and at a second end to the second portion. The elastic band acts as a tether for the second portion when the second portion is removed for playing the brass instrument.

Abstract: A new and improved sound reflector and a mouthpiece mount. The mouthpiece mount is secured to the sound reflector to position a mouthpiece adjacent to and generally perpendicular of the reflector.

Abstract: A plurality of tubular members are incorporated in a wind instrument for forming an air passage, and each of the tubular members has a tubular portion and a guide portion larger in diameter than the tubular portion and rounding therefrom for forming a hollow space open to the inner space of the tubular portion, thereby preventing the external appearance of the wind instrument from residual electrolyte confined during a plating bath.

Abstract: A brass instrument mouthpiece is described as incorporating an adjustable cup depth to enhance performance in the upper register of the instrument, without sacrificing tonal quality in the lower register. In accordance with a preferred embodiment of the invention, an interchangeable mouthpiece rim and sleeve are correspondingly threaded to flushingly fit together, and to receive a threaded mouthpiece shank and cup to an adjustable depth. A threaded lock is secured to the shank when the cup is located at the depth desired with respect to the rim, to then set the mouthpiece ready for use.

Abstract: A mouthpiece for a musical instrument having a body member with a tapered tubular backbore at one end engageable to fit a musical instrument and a cup and rim at its opposite end, each of which is detachably maintained together to form the mouthpiece. The cup is provided with a plurality of annular internal sections to create a predetermined resistance to air flow through the mouthpiece thereby controlling the tone produced with a change of the axial length of the sections resulting in a change in resistance and accordingly the tone.

Abstract: A musical instrument mouthpiece includes a tubular stem having a shoulder, with a removable sleeve in the stem engaging the shoulder at one end, a cup in the stem engaging the other end of the sleeve with a rim secured to the stem and engaging the cup to hold it against the sleeve and the sleeve against the shoulder.

Abstract: An intensifier for high notes is provided for insertion in the mouthpiece and instrument tube of a brass musical instrument, such as a trumpet or a trombone, which comprises a wire with an angularly disposed portion at one end and a freely oscillating enlargement or tongue at the other end for cooperation with the interior of the instrument tube.
