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.

A cargo tightener and strap collector is shown having a rotatable shaft provided on the lever portion of the cargo tightener and strap collector. A slot is provided in the shaft so that the free end of a strap may be inserted in the slot and wound on the shaft to secure the strap and prevent its fluttering in the wind or trailing on the ground while in use. The rotatable shaft provided on the lever portion of the cargo tightener and strap collector is made to have a cross-section or shape, at least proximate one end, to mate or interfere with a recess in at least one of the sidewalls on the lever portion when a second rotation means urges the sidewalls together. There is thus provided positive locking of the wound strap.

An apparatus for measuring tension in guy wire systems wherein the lower end of the guy wire has a thimble adjoined by a connection pin to a yoke or clevis of a turnbuckle shackle bolt connected to an earth anchor. A block assembly is removably received beneath the clevis and a thimble-engaging jaw assembly is removably received on the guy wire above the clevis. The block assembly and jaw assembly are connected at one end by a threaded rod assembly that includes a strain sensor connected with an indicator device, and by a threaded rod at their opposed end. The jaw assembly is drawn downward by adjusting nuts on the threaded rods beneath the block assembly to engage the thimble and move it downward transferring the tension to the threaded rod and threaded rod assembly which is sensed by the strain sensor and indicated by the indicator device.

The handle may be adjustable to increase the mechanical advantage of the lever. The handle may be rotatably connected to the lever to extend the length of the lever. The handle may be slidably connected to the lever, to slide between a compact position where the handle is closer to the spool, and an extended position where the handle extends further away from the spool.

Thermosetting adhesive compositions for use in e.g., particleboard or fiberboard, wherein the compositions comprise a blend of a protein-based component and a polymeric quaternary amine cure accelerant, can provide the fast tack-building and curing, as well as ultimately good bonding characteristics normally associated with synthetic resin compositions. Preferably, the polymeric quaternary amine cure accelerant is the reaction product of a polyamidoamine and epichlorohydrin.

A composite tension member. The composite tension member is assembled from a number of composite rods, each having two ends. A wedge plug is formed around the ends of the composite rods. The wedge plugs are inserted into termination fitting having a termination fitting body with an aperture at a proximal end for receipt of the bundle of composite rods and having an internal cavity that flares outwardly from a proximal end to a distal end to closely receive the wedge plug with the composite rods imbedded therein. A closeout nut is used to retain the wedge plug in the termination fitting body. The invention further provides method of manufacturing composite tension members.

A belt reel for fastening goods on a truck includes an axle extending through a main frame and a lever to pivotally mount the main frame and the lever to each other. The axle includes two opposite ends each having a ratchet wheel mounted thereto between the main frame and the lever and rotated with the axle. A slot is diametrically defined in the axle for allowing a belt extending through the axle. The main frame has a stop plate slidably mounted therein and selectively engaged to the ratchet, and the lever has a pawl slidably mounted therein. The pawl is engaged to the ratchet for driving the axle to reel the belt and separated from the ratchet for releasing the strain of the strained belt.

The invention is a quick adjusting choke winch, wherein in contrast to a winch where the strap is threaded from an end of the choke strap, the choke strap is side-threaded along a longitudinal edge. The invention is appropriately sized so that multiple width straps can be accommodated. The quick adjusting choke winch is comprised of: a base plate having a bearing; an open-ended split-center shaft; at least two pack rollers for controlling the tangential angle of strap being wound; a means for guiding the choke strap within the winch; a ratchet plate; a releasable main pawl; a releasable safety pawl; a means for turning the open-ended split-center shaft; a cover plate; and at least one fastening element for attaching the cover plate. The ratchet plate is co-axially affixed to the open-ended split-center shaft, so that when the ratchet turns the open-ended split-center shaft turns through the same rotation. Mounted on the same side of the plate are an end of the open-ended split-center shaft, an end of the at least two pack rollers, the means for guiding the strap, an end of the main pintle, and an end of the safety pintle. The cover plate is removably mounted to at least the pack rollers, and receives the open-end of the split-center shaft. The split-center of the open-ended split-center shaft has an opening that is sufficiently wide to receive the thickness of the choke strap.

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 cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit including a movable member to drive the rotation member and a release member to lock or unlock the movable member, and a locking unit to lock the release member onto the movable member releasably. Thus, the release member is locked onto the movable member by the locking unit and cannot be pulled upwardly to detach the push plates of the movable unit from the ratchet wheels of the fixed unit so that the ratchet wheels are locked to lock the rotation member to prevent the cable from being loosened so as to protect the cargo wound by the cable, thereby achieving the anti-theft purpose.

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.
