Bundle of wire

Another design which provides unusually low mating forces employs bundles of wires in both halves of the connector that intermesh, like two hair bmshes, when the parts ate connected (2). 

Many other opportunities exist due to the enormous flexibility of the preparative method, and the ability to incorporate many different species. Very recently, a great deal of work has been published concerning methods of producing these materials with specific physical forms, such as spheres, discs and fibres. Such possibilities will pave the way to new application areas such as molecular wires, where the silica fibre acts as an insulator, and the inside of the pore is filled with a metal or indeed a conducting polymer, such that nanoscale wires and electronic devices can be fabricated. Initial work on the production of highly porous electrodes has already been successfully carried out, and the extension to uni-directional bundles of wires will no doubt soon follow. 

Alloy with Memory. In seeking a way to reduce the brittleness of titanium, U.S. Navy researchers serendipitously discovered a nickel-titanium alloy having an amazing memory. Previously cooled clamps made of the alloy (nitinol) are flexible and can be placed easily in position. When warmed to a given temperature, the alloy hardware then exerts tremendous pressure. Use of conventional clamps for holding bundles of wires or cables in a ship or aircraft structure requires special tools. For this and other applications in industry and medicine, nitinol has been in demand. The alloy, however, is not easy to produce because only minor variations in composition can affect the snap back" temperature by several degrees of temperature. 

Mixing factors in case of wire-to-pin contact in the bundle of wire spaced fuel elements turned out to be higher than those for wire-to-wire contact. Counter-direction wires providing lateral coolant flows would be most effective.

Whenever possible, tendons are assembled in the factory. The wires are first measured off to the required length on a fully automatic cutting bench. Then the bundle of wires is passed through a template and the one anchor head, and button-heads are cold-upset onto the wires at this end. In order to make all the wires parallel, the tendon is then pulled through the template by pulling the anchor head. To keep the differences in the lengths of the wires in a curved duct to a minimum, and to preserve the parallelism of the wires even when they are wound onto reels for transport, the tendon is given three to five complete twists and then bound at intervals of approximately 3 m (approx. 10 ft). Once the tendons are reeled the factory work is finished. 

Unbonded tendons in the early systems used bundles of wires or strands, sometimes inaccurately called "cables," of various diameters and protected by grease and paper sheathing that were sometimes applied by hand. 

In our design, we use RS232 standard to interface PC with machine to control and acquire data. This contributes several problems when applied in hospitals. Therefore, we are developing alternative ways by using latest communication standards such as Wifi or Bluetooth, which helps our devices free from bundle of wires. 

The radiation facility consisted of a double-walled aluminum tube 7/8 in. in inside diameter which extended from the top of the LITR through approximately 20 ft of water into the reactor core. The autoclave was lowered into this tube on a bundle of wires containing the electrical leads,... 

Cuprous chloride, acid (for gas analysis, absorption of CO) cover the bottom of a 2-liter bottle with a layer of copper oxide % inch deep, and place a bundle of copper wire an inch thick in the bottle so that it extends from the top to the bottom. Fill the bottle with HCl (sp. gr. 1.10). The bottle is shaken occasionally, and when the solution is colorless or nearly so, it is poured into half-liter bottles containing copper wire. The large bottle may be filled with hydrochloric acid, and by adding the oxide or wire when either is exhausted, a constant supply of the reagent is available. 

The pneumatic tire has the geometry of a thin-wallcd toroidal shell. It consists of as many as fifty different materials, including natural rubber and a variety ot synthetic elastomers, plus carbon black of various types, tire cord, bead wire, and many chemical compounding ingredients, such as sulfur and zinc oxide. These constituent materials are combined in different proportions to form the key components of the composite tire structure. The compliant tread of a passenger car tire, for example, provides road grip the sidewall protects the internal cords from curb abrasion in turn, the cords, prestressed by inflation pressure, reinforce the rubber matrix and carry the majority of applied loads finally, the two circumferential bundles of bead wire anchor the pressnrized torus securely to the rim of the wheel. 

Among the additional data examined, the only non-normal characteristics found were for some of the results in (M10), which again, as in the earlier investigation (M4), apply to 19-rod bundles with wire-wrap supports. The consistent pattern that now seems to be emerging is that it is only the use of wires wrapped around the rods that causes nonnormal characteristics. It seems that the addition of a wrap around the complete bundle, as was the case for test sections No. 10 and 11 in Table V, prevents the nonnormal characteristics from appearing. 

Figure 6.8 Phthalocyanine 63 self-assembles in chloroform to give bundles of micrometer length fibers. Single fibers have diameter of 50 A (highlighted between arrows) and can be envisaged as nanowires (top left). Chiral derivative 64 forms left-handed super helices (top right) due to chirality within side chains. This chiral expression can be turned-off by addition of K+ ions, which bind within the crown-ether part of the molecule, forcing the phthalocyanines to be stacked directly on top of each other, resulting in straight wires (bottom left).

Nitridation of source metals occurs in the range of about 1 cm from the head of wire bundle, except for tungsten. Electron beam plasma generated along the beam path may greatly contribute to the nitridation process at an elevated temperature. 

Vaporization proceeds from the head of wire bundle. However, the vaporization mechanism of the nitride, i.e., whether the vaporization takes place through the decomposition of the nitride into metal vapor and nitrogen atoms or not, is not clear.

A typical arrangement of components in a tensimetric titration is presented in Fig. 9.5, which shows the previously discussed tensimeter and a calibrated bulb attached to a vacuum line.2 The sample container on the tensimeter is fitted with a small reciprocating stirrer which consists of a thin glass rod connected to a glass-encased headless nail or glass-encased bundle of soft iron wire. This stirrer is driven by an external solenoid, the field of which is switched on and off by a current-interrupting device, the details of which are laid out in Fig 9.6. The size of the calibrated bulb is chosen so that it will contain the desired amount of gas for each addition at a pressure which is convenient and accurately measured (e.g., 100-500 torr). The calibration procedure and steps used dispensing gas from such a bulb are described in Section 5.3.G. 

In the second approach to self-assembly of polymer-silica nanocomposites, polymerizable surfactants are employed both to direct self-assembly into ordered mesophases and to serve as organic monomers which can be subsequently polymerized. For instance, Brinker et al. developed nonionic surfactants incorporating diacy-telene groups which could be polymerized upon irradiation by UV light.68 69 Similarly, poly(thiophene)70 and poly(pyrrole)71 have been successfully integrated into silica nanostructures in this manner. Importantly, this in situ polymerization produces isolated molecular wires, rather than clustered bundles of conductive polymer.70...
