Cellulose media
| Oil glossary |
A filter material made from plant fibers. because cellulose is a natural material, its fibers are rough in texture and vary in size and shape. compared to synthetic media, these characteristics create a higher restriction to the flow of fluids.

Media, английский
- Missile era data integration analysis
- Same as tunica media
- A generic term for systems of production and dissemination of information and entertainment and of exertion of various kinds of social controls. unlike a channel which is limited to a contiguous physical medium between the sender and a receiver of communications, media include the institutions which determine the nature, programming and form of distribution. e.g., mass media is the generic term for newspapers, book publishing, radio and television. other media include the recording industry, movie industry and theatre. all media are associated with more or less elaborate forms of audience participation.
- An api for audio, imaging, and video multimedia.
Characteristics, английский
- The distinguishing qualities of a navigation aid or buoy, including shape and color, whether fixed or flashing, and flashing sequence.
- A high-performance fiber with high chemical resistance that does not burn in air. it has no melting point and does not drip when exposed to flame. the fiber and fabrics from pbi retain their flexibility, dimensional stability, and significant strength without embrittlement even when exposed to flame or extreme heat. the fiber emits little smoke in extreme conditions. it processes well on conventional textile equipment, having processing characteristics similar to polyester. it can be used in 100% form or blended with other fibers. it has a high moisture regain and low modulus with comfort properties similar to cotton. the natural color of pbi is a gold-khaki shade, but it can be dyed to almost any medium to dark shade with conventional basic dyes.
- Acetate fabrics are in appearance fast-drying, wrinkle and shrinkage resistant, crisp or soft in hand depending upon the end use.
- Although modacrylics are similar to acrylics in properties and application, certain important differences exist. modacrylics have superior resistance to chemicals and combustion, but they are more heat sensitive (lower safe ironing temperature) and have a higher specific gravity (less cover).
- Although the properties of the nylons described above vary in some respects, they all exhibit excellent strength, flexibility, toughness, elasticity, abrasion resistance, washability, ease of drying, and resistance to attack by insects and microorganisms.
- Because acrylic fibers are thermoplastic, fabrics may be heat-set for wrinkle resistance and to provide permanency to pleats. acrylic fabrics have low moisture absorbency and dry relatively quickly. in general, acrylic fibers are resistant to the degrading effects of ultraviolet rays in sunlight and to a wide range of chemicals and fumes. they provide warmth in fabrics that are lightweight, soft, and resilient. acrylic fibers have relatively poor flame resistance compared with other fibers. some acrylic fabrics, particularly knit types, approximate the hand of fine wool. because of the composition and cross section of the fiber, fabrics made therefrom have a high bulk to weight ratio. this is further enhanced with the so-called “high bulk” spun yarns.
- Glass fiber is incombustible and will tolerate heat up to 1000°f without material damage. potential strength is not realized in woven fabrics or even in yarns, because the fiber is brittle and fracture points may develop, but nevertheless, very high tensile strength is obtained in woven fabrics, and is retained at elevated temperatures. the fiber originally was difficult to color but methods have been developed to accomplish this. moisture absorption is low. electrical and insulation resistance is high.
- Polychlal fibers have a soft, lamb’s wool-like hand and moderate moisture regain. the fibers are also characterized by high flame resistance and high abrasion resistance.
- Polyester fibers have high strength and are resistant to shrinking and stretching. fabrics are quick drying and tend to have wrinkle resistance and crease retention, wet and dry. polyester is used alone and in blends. it has been one of the first fibers to be developed in fabrics with durable-press features.
- Polyethylene fibers have a low specific gravity, extremely low moisture regain, the same tensile strength wet and dry, and are resistant to attack by mildew and insects. these qualities have made polyethylene fiber suitable for industrial applications, geotextiles, outdoor furniture, and similar applications. polyethylene fiber does not dye, and in most cases, it is colored by the addition of pigments and dyes to the material prior to spinning. it has a low melting point, a property that has restricted its use in apparel.
- Polypropylene fibers have a number of advantages over polyethylene fibers in the field of textile applications. the degree of crystallinity, 72 to 75%, results in a fiber that is strong and resilient, and does not fibrillate like high-density polyethylene. polypropylene has a high work of rupture, which indicates a tough fiber, and may be made with tenacities as high as 8.0 to 8.5 grams per denier. the melting point of polypropylene is 165°c, which is low by comparison with nylon or polyester, but is high enough to make it suitable for most textile applications. so light that it actually floats, polypropylene fiber provides greater coverage per pound than any other fiber. it is highly resistant to mechanical abuse and chemical attack.
- Rayon yarns are made in a wide range of types in regard to size, physical characteristics, strength, elongation, luster, handle, suppleness, etc. they may be white or solution dyed. strength is regulated by the process itself and the structure of the yarn. (also see polynosic fiber.) luster is reduced by including delustering materials, such as titanium dioxide pigments, in the fiber when it is extruded. the suppleness of the yarn is controlled by the number of filaments in the yarn, the denier or gauge of the individual filaments or fibers, and the fiber cross-section.
- Spandex is lighter in weight, more durable, and more supple than conventional elastic threads and has between two and three times their restraining power. spandex is extruded in a multiplicity of fine filaments which immediately form a monofilament. it can be repeatedly stretched over 500% without breaking and still recover instantly to its original length. it does not suffer deterioration from oxidation as is the case with fine sizes of rubber thread, and it is not damaged by body oils, perspiration, lotions, or detergents.

- If two or more independent and distinct inventions are claimed in a single application, the examiner may require the applicant to elect (designate) a single invention to which the claims will be restricted (limited to). this requirement is known as a requirement for restriction (also known as a requirement for division). such requirement will normally be made before any action on the merits; however, it may be made at any time before final action (final rejection).
- If a single application claims two or more independent and distinct inventions, the examiner may need the applicant to elect a single invention to which the claims have restrictions. this is a rule for restriction.

Cavitation erosion, английский
- A material-damaging process which occurs as a result of vaporous cavitation. "cavitation" refers to the occurrence or formation of gas- or vapor- filled pockets in flowing liquids due to the hydrodynamic generation of low pressure (below atmospheric pressure). this damage results from the hammering action when cavitation bubbles implode in the flow stream. ultra-high pressures caused by the collapse of the vapor bubbles produce deformation, material failure and, finally, erosion of the surfaces.
- Loss of material due to the repeated formation and collapse of bubbles at the surface of an object in contact with a rapidly flowing liquid. glossary c 493 celsius (centigrade): temperature scale based on 273 k (0 °c = +32 °f) as the freezing point of water and 373 k (100 °c = 212 °f) as the boiling point of water at standard atmospheric pressure. a relative scale related to the kelvin scale (0 °c = 273.12 k; 1 °c = 1 k).
