[One] type of flute is a globular flute, also called a vessel flute. "Ocarina" is a common name for one of the most common types of globular flutes. Unlike their tubular flute cousins, globular flutes can be any shape, but still have finger holes and a blow hole, and are played in generally the same fashion as a tubular flute.... The physics of sound production is significantly different between tubular and globular instruments. In a tubular instrument, a vibrating column of air produces the sound. The length of this air column is the primary factor determining the pitch. However, the pitch can be modified by uncovering toneholes along the body of the instrument, which effectively shorten the length of the air column and raise the pitch. But with globular instruments, the shape of the air contained within the vessel is generally irrelevant to the pitch. It's the total volume of air contained in the vessel and the size of the opening that determines the pitch. 2, record 1, English, - globular%20flute

Unified and American National screw thread standards for screws, bolts, nuts, and other threaded parts consist of six series of threads and a selection of special threads that cover nonstandard combinations of diameter and pitch. In general the unified screw threads are limited to three series : coarse(UNC), fine(UNF), and extrafine(UNEF). A 1/4-inch-diameter thread in the UNC series has 20 threads/in., while in the UNF series it has 28... The fine thread series(UNF and NF) is recommended for general use in the automotive and air craft fields for threads subject to strong vibration. In general, a fine thread should be used only where close adjustment, extra strength, or increased resistance to loosening is a factor. 3, record 5, English, - National%20Fine%20screw%20thread

Threads are designated by standardized notes. Under the unified system, threads are specified by giving in order the nominal diameter, number of threads per inch, the initial letters such as UNC or UNF that identify the series, and class of thread (1A, 2A, and 3A or 1B, 2B, and 3B). Threads are considered to be right-hand and single unless otherwise noted; therefore the specification for a left-hand thread must have the letters LH included. 2, record 6, English, - Unified%20National%20Fine%20screw%20thread

Norme BS 1580 : 1953 "Unified Screw Threads". Il s'agit des filetages cylindriques de mécanique générale, au profil ISO, mais avec les cotes en pouces. Depuis 1949, le Royaume-Uni, le Canada et les États-Unis se sont mis d'accord sur ces filetages et leur désignation : "UNC" pour "Unified coarse thread" (gros pas). "UNF" pour "Unified fine thread" (pas fin). "UNEF" pour "Unified extra-fine thread" (pas extra-fin). "UN" pour "Unified constant pitch" (pas constant).
