Abstract: An adjustable frame for holding paint roller comprising: a pair of square arms, each of the square arms includes a distal part, a joint part, a pair of shafts at the ends of the distal parts, and a pair of racks which are opposite to each other and are respectively fixed at the ends of the joint parts; and a straight square tube which holds to the pair of joint parts and holds the pair of racks into its internal space, the pair of racks meshing with a gear wheel within the internal space of the square tube; a tee-joint which holds to the square tube, a pair of bearing holes through their walls holding up a bar to which the gear wheel is fixed, and one knob being fixed to one of two ends of the bar outside the wall of tee-joint. The present invention provides a holding-length adjustable frame that is capable of flexibly and tightly clamping and holding a variety of longitudinal sizes of paint rollers.

Abstract: This invention relates to a mesoporous carbon material in the form of filaments having a high surface area. A process is also provided to produce mesoporous carbon material of high surface area. The process comprises drying a carbon material, surface oxidizing the dried material, stabilizing the surface oxidized material, and activating the stabilized material to produce a highly activated, mesoporous material.
