Vibratosax
Vibratosax is the product name of the saxophones made from plastic, designed & built by the Thai company Vibrato. A global patent makes Vibrato Co., Ltd. the sole manufacturer of saxophones, whose parts are mainly created from injection-molded plastic. Currently only Alto saxophones are available, Tenor and Soprano (curved) models have been developed and announced. Historical reference – the Grafton Acrylic Saxophone The Grafton saxophone was an Alto saxophone with a plastic body, available between 1950 and approx. 1968. The saxophone had very good musical properties, amongst others. It has been played by some of the biggest jazz musicians such as Charlie Parker and Ornette Coleman. Besides its heavy weight, the saxophone's very brittle, ivory-tinted acrylic shaped using low-pressure molding proved to be another disadvantage. It led to the body's tendency to become irreparably damaged easily, especially on the bow. The weight was mainly caused by the mechanics, which had bee ...

Saxophone
The saxophone (often referred to colloquially as the sax) is a type of Single-reed instrument, single-reed woodwind instrument with a conical body, usually made of brass. As with all single-reed instruments, sound is produced when a reed (mouthpiece), reed on a Mouthpiece (woodwind), mouthpiece vibrates to produce a sound wave inside the instrument's body. The Pitch (music), pitch is controlled by opening and closing holes in the body to change the effective length of the tube. The holes are closed by leather pads attached to keys operated by the player. Saxophones are made in various sizes and are almost always treated as transposing instruments. Saxophone players are called ''wikt:saxophonist, saxophonists''. The saxophone is used in a wide range of musical styles including classical music (such as concert bands, chamber music, List of concert works for saxophone, solo repertoire, and occasionally orchestras), military bands, marching bands, jazz (such as big bands and jazz comb ...

Grafton Saxophone
The Grafton saxophone was an injection moulded, cream-coloured acrylic plastic alto saxophone with metal keys, manufactured in London, England by the Grafton company, and later by 'John E. Dallas & Sons Ltd'. Grafton made only altos, owing to the manufacturing challenges presented by larger models (e.g., the tenor) with 1950s plastic technologies. Production commenced in 1950 and ended after approximately ten years. However, a few last examples were assembled from residual parts circa 1967. All tools, machinery, and jigs required to manufacture the Grafton were sold for scrap and subsequently destroyed in 1968. Design Designed by Hector Sommaruga, an Italian living in London, the saxophone was named after "Grafton Way", his address during the early 1950s. The basic saxophone design was patented in late 1945. Creation of the first non-working prototype took place in 1946, and commercial production commenced in 1950. The selling price of the Grafton was £55 i.e. approximately hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and ...

President (corporate Title)
A president is a leader of an organization, company, community, club, trade union, university or other group. The relationship between a president and a chief executive officer varies, depending on the structure of the specific organization. In a similar vein to a chief operating officer, the title of corporate president as a separate position (as opposed to being combined with a "C-suite" designation, such as "president and chief executive officer" or "president and chief operating officer") is also loosely defined; the president is usually the legally recognized highest rank of corporate officer, ranking above the various vice presidents (including senior vice president and executive vice president), but on its own generally considered subordinate, in practice, to the CEO. The powers of a president vary widely across organizations and such powers come from specific authorization in the bylaws like '' Robert's Rules of Order'' (e.g. the president can make an "executive decision" o ...

Silicone
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coil Spring
A selection of conical coil springs The most common type of spring is the coil spring, which is made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae - the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs. Coil springs can be either compression springs, tension springs or torsion springs, depending on how they are wound. A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. They are commonly used in mattresses, automotive suspensions, and residential plumbing. Coil springs come in a variety of sizes and shapes and can be used for a variety of applications. Small coil springs are often us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neck (music)
The neck is the part of certain string instruments that projects from the main body and is the base of the fingerboard, where the fingers are placed to stop the strings at different pitches. Guitars, banjos, ukuleles, lutes, the violin family, and the mandolin family are examples of instruments which have necks. Necks are also an integral part of certain woodwind instruments, like for instance the saxophone. The word for neck also sometimes appears in other languages in musical instructions. The terms include ''manche'' (French), ''manico'' (Italian), and ''Hals'' (German). Guitar The neck of a guitar includes the guitar's frets, fretboard, tuners, headstock, and truss rod. The wood used to make the fretboard will usually differ from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Strings and tuning), and the ability of the neck to resist bending (see Truss rod) is important to th ...

Wind Instrument
A wind instrument is a musical instrument that contains some type of resonator (usually a tube) in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece, while yet others require the player to blow into a hole at an edge, which splits the air column and creates the sound. Methods for obtaining different notes * Using different air columns for different tones, such as in the pan flute. These instruments can play several notes at once. * Changing the length of the vibrating air column by changing the length of the tube through engaging valves ''(see rotary valve, piston valve)'' which route the air through additional tub ...

ABS Plastic
Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)''x''·(C4H6)''y''·(C3H3N)''z'' is a common thermoplastic polymer. Its glass transition temperature is approximately . ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The polybutadien ...
