    摘要： A method of making a polishing pad having a body comprising fibers embedded in a matrix polymer formed by a reaction of polymer precursors. The fibers define interstices, and the precursors fill these interstices substantially completely before completion of the reaction. The method comprising placing the fibers and the precursors in a cavity of a mold for shaping the polishing pad; applying a differential pressure across a mold cavity, where the differential pressure and the amount of precursors are sufficient to cause the precursors to fill the interstices substantially completely before completion of the reaction; and applying sufficient heat to the mold to at least partially cure the polishing pad by causing the precursors to react.

    摘要： A method for erecting a platform is provided. The method includes providing a selectively liftable platform mechanism wherein the platform mechanism generally includes a platform, a trailer, and a support structure on the trailer. The support structure includes a ladder having a distal end pivotally connected to the platform, and a proximal end pivotally and slidably connected to the trailer. The proximal end of the ladder is movable along the longitudinal axis of the trailer in order to level the platform in a raised position. The support structure further includes at least one support bar having a proximal end pivotally connected to a first end of the trailer, and a distal end pivotally connected to the platform. The platform mechanism further includes a stop member to limit longitudinal movement of the proximal end of the ladder towards a second end of the trailer, and an erection assembly. The method next includes using the erection assembly to rotate the at least one support bar and the ladder so as to raise the platform from a lowered position adjacent the trailer, to a raised position. The method also includes sliding the proximal end of the ladder towards the second end of the trailer to engage the stop member, thereby limiting further longitudinal movement of the proximal end of the ladder towards the second end of the trailer, and thereby leveling the platform in its raised position.

    摘要： A selectively liftable platform mechanism is first provided. The platform mechanism generally includes a trailer, a platform, and a support structure on the trailer for pivotally raising the platform from a lowered position to an elevated position. The support structure includes a ladder having a distal end pivotally connected to the platform and a proximal end pivotally and slidably connected to the trailer. The proximal end of the ladder is movable along the longitudinal axis of the trailer in order to level and stabilize the platform into a viewing position. A method for erecting a shooting house is also provided. The shooting house is positioned onto the liftable platform mechanism.
