Process for producing directly mold-pressed fiber board

The invention belongs to the technical field of production of artificial boards, and relates to a process for producing a novel mold-pressed door board base material, in particular to a process for producing a mold-pressed fiber board by controlling the density distribution and fiber morphology of the cross section of the fiber board. According to the technical scheme, fibers treated by the hot grinding process are screened by a multi-layer sieve on the basis that the original equipment and the traditional process are not changed, and fibers in the following states are selected and treated by the next process, namely fibers which do not pass through a sieve pore with the pore diameter of 0.8mm account for 10 to 20 percent of the total mass of the fibers, fibers which pass through the sieve pore with the pore diameter of 0.8mm but do not pass through a sieve pore with the pore diameter of 0.125mm account for 60 to 80 percent of the total mass of the fibers, and fibers which pass through the sieve pore with the pore diameter of 0.125mm account for less than 10 percent of the total mass of the fibers. Through the technical scheme, interweaving performance among the fibers can be enhanced, the plasticity and flexibility of the board are improved, the requirement of direct mold pressing is met, and the phenomena of layering and cracking during mold pressing are avoided.

Side arm release system for eyeglass frame with changeable temple pieces

A side arm release system for an eyeglass frame includes front frame having outer edges, each of the edges terminating in a vertical line substantially parallel to a plane defined by the eyeglasses or the like held within the front frame. The vertical line functions as a fulcrum for the release function. The system further includes a pair of axle journals, one each of the journals of the pair integrally depending from the inner surface of each outer end of the front frame, the journal projecting in a direction generally normal to the plane of the eyeglasses held within the front frame. The journals are located proximally to the fulcrum within a dimension having a width of the forward-most ends of side arms. The system also includes a pair of male bayonet clips, each rotationally dependent at one end from axles within respective the journals of the eyeglass frame, and inwardly of the fulcrum in the direction of a nose bridge of the front frame. Each of the temple pieces exhibit a forward end terminating in a vertical camming surface which contacts the fulcrum upon rotation of the arms or temple members. A pair of female bayonet clips are proportioned for complemental engagement of opposing male bayonet clips, the female clips formed integrally upon inner sides of each temple piece proximally to each of the male bayonet clips when the male clips are press- fitted into the female clips. The outward rotation of temple members causes a lever action of the camming surface upon the fulcrum, pulling on the male bayonet clip. Rotation of the eyeglass frame oppositely in direction to the rotation of the side arm will also pull the male bayonet clip out of engagement with its associated female clip and in the direction of the eyeglass frame.
