When weaving on a loom, the beads are locked in between the Warp weaving warp threads by the weft threads. The most common bead weaving technique requires two passes of the weft thread. First, an entire row of beads is strung on the weft yarn thread . Then the beads are pressed in between the warp threads. The Sewing needle needle is passed back through the beads above the warp threads to lock the beads into place. Heddle looms were popular near the beginning of the 20th century. They allowed weaving of beads by raising every other thread and inserting strung beads in the shed, the space between the lowered and raised threads. There are still a few Heddle Bead Looms being manufactured today. The most difficult part of loomwork is finishing off the warp threads. Although loomed pieces are typically rectangular, it is possible to increase and decrease to produce angular or curvy shapes. Fringe trim Fringe can also be added during weaving or before the piece is removed from the loom. Bead looms vary in size and are typically made of wood or metal. Usually, a comb or Spring device spring is used to hold the warp threads a bead width apart. Some looms have roller bars that allow the weaver to produce pieces that are longer than the loom.

Wheels for automobile s, bicycle s, etc. are made with a small slot or groove for the tire bead to sit in. When the tire is properly inflated the air pressure within the tire keeps the bead in this groove. When putting a new tire on a wheel, there is the problem of sealing or setting the bead the tire will not inflate if the incoming air can escape. Some people spray starter fluid or WD40 into the tire and then light it to set the bead. ref http quad.transworld.net 2007 04 17 workshop tire mounting made easy Tire Mounting Made Easy Dead link date May 2011 ref ref http www.youtube.com watch?v zZhszvMjvjg Seal A Tire Bead with Starting Fluid ref It is common amongst drivers of off road vehicle s to decrease the air pressure in their tires.

If the pressure is too low there may not be enough pressure to keep the bead on the wheel thus causing the bead to pop off the wheel. This is often referred to as losing a bead . Beadlock s, which clamp the bead on the wheel, are often used in this case. Often, the bead can become frozen to the rim after rusting occurs, requiring the use of a bead breaker .

The inside ring of the tire is called the lip, and the bead on the lip seals to the rim in a radial ply tire , trapping the air inside. Often, the bead can become frozen to the rim after rusting occurs, requiring the use of a bead breaker in order to be removed. A need was experienced by avid 4x4 enthusiasts and overland travel ers for a simple tool to effectively and efficiently remove the tire from the rim of a wheel, in cases where a tire requires repairs to the inside. Automated equipment exist for removing tires but due to the high cost and lack of portability these are were not suitable. In addition beads frozen by heat and rust to the rim must often be broken free manually. In these case the bead breaker is ideal.

Bead embroidery is a type of beadwork that uses a needle and thread to stitch beads to a surface of fabric, suede, or leather. Bead embroidery is an embellishment that does not form an essential part of a textile s structure. In this respect, bead embroidery differs from bead weaving , bead crochet , and bead knitting .

Traditionally, bead embroidery has been used on clothing and decorative textiles. It may be used in jewelry with the addition of structural supports such as bracelet bands. Other clothing accessories such as belt buckles and handbags can be embroidered with beads, and household items such as pillows or boxes may be embellished with bead embroidery. When used with hard surfaces, bead patterns are measured and planned with seam allowances and attached after embroidery by means of glue or epoxy . Technique Three basic methods may be used to embroider with beads individual beads may be sewn directly onto fabric, or several beads may be run through a needle before running through the backing, or else a line of threaded beads may be laid upon a fabric and secured with couching stitches. ref name worldtex cite book title World Textiles A Visual Guide to Traditional Techniques author John Gillow and Bryan Sentance publisher Thames & Hudson date 1999 page 216 ref References Reflist beadwork Category Embroidery Category Beadwork ru ... more details

The bead theory is a disproved hypothesis that gene s are arranged on the chromosome like bead s on a necklace . According to this theory, the existence of a gene as a unit of inheritance is recognized through its mutant alleles. A mutant allele affects a single phenotypic character, maps to one chromosome locus, gives a mutant phenotype when paired and shows a Mendelian ratio when intercrossed. Several tenets of the bead theory are worth emphasizing 1. The gene is viewed as a fundamental unit of structure , indivisible by crossing over. Crossing over take place between genes the beads in this model but never within them. 2. The gene is viewed as the fundamental unit of change or mutation . It changes in toto from one allelic form into another there are no smaller components within it that can change. 3. The gene is viewed as the fundamental unit of function although the precise function of gene is not specified in this model . Parts of a gene, if they exist cannot function. Seymour Benzer showed in the 1950s that the bead theory was not correct. He demonstrated that a gene can be defined as a unit of function. A gene can be subdivided into a linear array of sites that are mutable and that can be recombined. The smallest units of mutation and recombination are now known to be correlated with single nucleotide pairs.

Image Chevronbeads.jpg thumb right Chevron beads Chevron beads are special glass bead s the first specimen s of this type were created by glass bead makers in Venice and Murano , Italy , toward the end of the 14th century. They may also be referred to as rosetta, or star beads. The term rosetta first appeared in the inventory of the Barovier Glass works in Murano, in 1496, in context with beads as well as with other glass objects. Venetian chevron beads are drawn beads, made from glass canes , which are created in specifically constructed star mould s. The first chevron beads were made towards the end of the 15th century, consisting of 7 layers of alternating colours. They usually have 6 facet s. Unlike their later counterparts, they were not always made with the standard 12 point star mould. By the beginning of the 20th century, 4 and 6 layer chevron beads appear on various sample cards. According to records kept at the Societa Veneziana Conterie of Murano, they stopped making chevron canes during the 1950s. Chevron beads are still being made in Venice today, albeit in very small quantities. Chevron beads can be composed of a varied number of consecutive layers of colored glass es.
