Wrap around

A ring specimen is cut from the tube. Two coils are wrapped around this ring, one exciter coil and one receiver coil. The exciter coil N1 should cover the entire ring so that there are no field losses when ring is saturated. The sinusoidal exciter current which can be measured at... 

All of the pieces pictured here are not going to fit perfectiy into each other and that s going to cause all sorts of leaks. The answer is teflon tape. Strike loves teflon tape This inexpensive product is found in the plumbing department of any hardware store and is the duct tape of the next century. Teflon tape is chemically and thermally indestructible. This stuff is wrapped around any piece of pipe or joint, said part then jammed into its appropriate receptacle and the tape will mold to form a perfect fit. Hell, it can mummify a whoie joint compiex to make it absolutely impregnable. 

The sequence of amino acids in a peptide can be written using the three-letter code shown in Figure 45.3 or a one-letter code, both in common use. For example, the tripeptide, ala.ala.phe, could be abbreviated further to AAF Although peptides and proteins have chain-like structures, they seldom produce a simple linear system rather, the chains fold and wrap around each other to give complex shapes. The chemical nature of the various amino acid side groups dictates the way in which the chains fold to arrive at a thermodynamically most-favored state. 

The first differential centrifugal extractor to be used in industry was the PodbieHiiak extractor which was introduced in the 1950s (209,210) and can be regarded as a perforated-plate column wrapped around a rotor shaft. Rotation creates a centrifugal force which results in a great reduction in the equivalent height and contact time that would be needed in a conventional perforated-plate column. 

One ASTM test procedure has suggested (24) that foamed plastics be classified as either rigid or flexible, a flexible foam being one that does not mpture when a 20 x 2.5 x 2.5 cm piece is wrapped around a 2.5 cm mandrel at a uniform rate of 1 lap/5 s at 15—25°C. Rigid foams are those that do mpture under this test. This classification is used in this article. 

A small quantity of flexible packaging material, usually oriented polypropylene, shrink polypropylene, or polyethylene, is used to overwrap paperboard cartons. The film is wrapped around the carton and sealed by heating. Products such as boxed chocolates, candies, and cookies are overwrapped, sometimes by a printed film. 

A belt press commonly uses two belts of woven material. Fmit mash is deposited on, and spread out evenly between, the two belts which converge and press the mash between them. The belts wrap around a series of successively smaller cylinders or pass between rollers (less efficient) for the pressing action. Juice yield for the wraparound belt press is 72%, and increases to 92% with secondary water addition (15). 

Data Communication Wires. Electronic cables such as data communication wires employ three basic designs coaxial, twisted pair, and fiber optics (3,4) (Eig. 1). Coaxial cables are so named because the axis of curvature of its outer conductor is concentric to its inner central wire. The metal braiding wrapped around the insulated center wire acts as the return current conductor in addition to shielding the wire from various interferences. 

Ziac foil coated with a conductive, pressure-sensitive adhesive is used for repair of other ziac coatings or for imparting corrosion resistance at field sites. The 0.08-mm ziac tape or sheet has a 0.025-mm coaductive adhesive. The laminate is cut to size and pressed tightly to activate the adhesive. Conductive tape can be wrapped around pipe, especially around welds or connections. The corrosion resistance of this material is iatermediate between galvanized or thermally sprayed coatings and zinc-filled paints (21,50). 

Electrostatic spraying is used in shops to coat conductive objects. It is very useful for odd-shaped objects such as wire fence, cables, and piping. An electrostatic potential of 60,000 volts on the object attracts oppositely-charged paint particles the spray can wrap around and coat the side of the object opposite to the spray gun. This technique produces very uniform finishes and has the least paint loss of the three methods. However, it is slow, requires expensive equipment, produces only thin coats, and is sensitive to wind currents. 

Once the plant is ready, the cotton is mechanically harvested with either a spindle picker or cotton stripper. The spindle picker selectively harvests seed cotton from open boUs. The unopened boUs are left on the plant and can be picked at a later date. The spindle picker uses a rotating tapered barbed spindle to remove the cotton from the bur (seed case). The seed cotton is wrapped around the spindle, pulled from the bur, removed from the spindle with a mbber doffer, and then transferred to a basket. 

Colorfastness to decatiziag, ISO 10S-E10, iavolves a specimen wrapped around a perforated cylinder and through which steam is passed for 15 min at different pressures or temperatures to represent mild or severe conditions. In colorfastness to steaming, ISO 105-E1 /, a specimen and adjacents are roUed iato a cylinder and placed ia the neck of a flask of boiling water for 30 min. 

Of interest is the manner in which cavities of the appropriate size are introduced into ion-selective membranes. These membranes typically consist of highly plasticized poly(vinyl chloride) (see Membrane technology). Plasticizers (qv) are organic solvents such as phthalates, sebacates, trimelLitates, and organic phosphates of various kinds, and cavities may simply be the excluded volumes maintained by these solvent molecules themselves. More often, however, neutral carrier molecules (20) are added to the membrane. These molecules are shaped like donuts and have holes that have the same sizes as the ions of interest, eg, valinomycin [2001-95-8] C H QN O g, and nonactin [6833-84-7] have wrap around stmctures like methyl monensin... 

Surfaces exposed to water contained many localized areas of wastage (Fig. 6.22). Corroded areas were covered by brittle black or brown caps over irregular metal-loss regions. Many small fibers were embedded in corrosion products, and many more were wrapped around surfaces. Most fibers were about 0.001 in. (0.003 cm) in diameter and were hollow. 

Electrostatic method This is also a w et method like the conventional process, except that the paint is now electrostatically charged, similar to the powder ptiint in a dry method as discussed later. The paint, being highly charged electrostatically, is wrapped around the object automatically.

In the complex with Gpy the two phosducin domains do not interact with each other, instead they wrap around the edge and the top side of the p propeller, to form an extensive interaction surface (Figure 13.17). The N-terminal domain of phosducin interacts with all of the top loops of the p propeller including part of the surface of Cpythat interacts with Gq (Figures 13.15 and 13.17). This interface between phosducin s N-terminal domain and Gpy clearly precludes association of the latter with Gq. 

In order to process larger quantities of coal, an extraction reactor was constructed. The extractor was essentially a standing metal cylmder sealed on the bottom, approximately 30 cm in diameter and 84 cm in length. An electrical belt-driven stirring mechanism was fitted through the top of the reactor to provide mixmg, and three elechical band heaters were wrapped around the outside to supply process heat. A water-cooled condenser was also installed to condense NMP durmg reflux The system could routinely extract 1 to 2 kg of coal with 20 to 25 L of NMP. 

Use completely welded full wrap-around reinforcement pads at branch connections with pad thickness equal to header wall thickness. 

Use wrap-around reinforcement at welded support shoes and anchors. Alternatively, all welding of these fittings to the pipe wall may be eliminated by the use of bolted shoes and anchors.
