To provide an infrared-shielding body sufficiently transmitting visible rays, having no half-mirror shaped appearance, requiring no large-scale apparatus when forming a film on a substrate, efficiently shutting invisible near-infrared rays with wavelength range of 780 nm or more, while eliminating a heat treatment at high temperature after film formation, and having a spectral characteristic such as transparency with no change of color tone. The starting material, which is a mixture containing a predetermined amount of a tungsten compound, is heated at 550° C. in a reductive atmosphere for 1 hour, then cooled to room temperature once in an argon atmosphere, thus producing powder of W18O49. Then, the powder, the solvent, and the dispersant are mixed, then subjected to dispersion treatment to obtain a dispersion solution. The dispersion solution and a UV-curable hardcoat resin are mixed to obtain a solution of fine particle dispersion of infrared-shielding material. The solution of the fine particle dispersion of infrared-shielding material is applied on a PET resin film to form a film, which is then cured, and an infrared-shielding film having a transmission profile shown in the figure is thereby obtained.

Equipment and associated methods for replacing existing overhead transmission line conductors with new ones while the transmission line remains in service and carrying power. The old conductor is used to pull the new conductor through a series of sheaves installed at the bottom of the insulator at each tower. Conventional tension-stringing equipment is used but it is elevated to line potential that is achieved by use of an insulating platform or insulating jacks. Current transfer between stationary and moving conductors is achieved by a current transfer device that may consist of transmission line contacting wheels and liquid metal contactors. Sag control in various conductor spans is enhanced by a stringing block with controllable friction. Equipment is also introduced which will prevent release of the conductor by the pulling device should it break while engaged by that device.

A force-indicating strap fastener includes a base, an axle, a lever, two ratchet wheels, a first detent, a second detent, and a force gauge. The base including a first guiding element formed thereon and a second guiding element formed thereon. The axle is rotationally mounted on the base. The lever is pivotally mounted on the axle. The ratchet wheels are secured to the axle. The first detent is mounted on the base for engagement with the ratchet wheels. Thus, rotation of the axle relative to the base in a first direction is allowed, but rotation of the axle in a second direction opposite to the first direction is avoided. The second detent is mounted on the lever for engagement with the ratchet wheels. Thus, pivoting of the lever in the first direction results in rotation of the axle in the first direction, but pivoting of the lever in the second direction does not entail rotation of the axle in the second direction. The force gauge includes a casing, a spring, an anvil and an indicator. The casing is mounted on the base and formed with a scale. The spring is received in the casing. The anvil includes a first end in contact with the spring and a second end outside the casing. The indicator is connected with the anvil for pointing at a value in the scale depending on the tensile force.
