摘要： A horizontal vibrating multi-deck screen apparatus for separating different sizes of materials of generally the same type. The apparatus includes a first or upper screening basket and a second or lower screening basket. The upper screening basket has a feed chute at one end and a discharge chute at the opposite end. Each screening basket has at least one screen deck thereon for conveying and screening material. The two baskets are connected by a spring-type coupling system, including coil springs and fiberglass leaf springs. The two baskets together are supported by known types of support spring systems installed between the upper basket only and a base frame. Hence each basket constitutes one mass and each spring system one spring of a two-mass two-spring system. A pair of shaker motors mounted directly, one on each side, on the lower basket inputs a straight-line sinusoidal exciting force to the system. The exciting force and the spring forces are transmitted to both baskets and induce vibrations. By adjusting and controlling the masses of the baskets, the spring rates of the two spring systems and the magnitude of the exciting force, the desired vibrations will be achieved, with the operating frequency maintained near but below the upper natural frequency of the apparatus.
摘要翻译：一种水平振动多层筛网装置，用于分离大体上相同类型的不同尺寸的材料。该装置包括第一或上筛选篮和第二或下筛网。上筛网在一端具有进料槽，在相对端具有排料槽。每个筛篮具有至少一个筛板，用于输送和筛选材料。两个篮子通过弹簧式连接系统连接，包括螺旋弹簧和玻璃纤维板簧。两个篮子一起由已知类型的支撑弹簧系统支撑，该弹簧系统仅安装在上部篮子和底座之间。因此，每个篮子构成一个质量，并且每个弹簧系统是双质量双弹簧系统的一个弹簧。一对振动电机直接安装在每个侧面，一个在下部的篮子上，向系统输入一条直线的正弦激励力。激发力和弹簧力传递到两个篮子并引起振动。通过调节和控制篮子的质量，两个弹簧系统的弹簧速率和激振力的大小，将实现期望的振动，其工作频率保持在设备的上固有频率附近但低于设备的上固有频率。

摘要： An apparatus for electrostatically coating powder on a flat panel and a method for using such apparatus are provided. In the apparatus, a heating device is used to heat a panel to be coated and positioned on a powder spray chamber to a temperature of at least 100° C. and simultaneously charging the panel with a negative voltage of at least 20,000 volts. The high temperature and the high voltage of the otherwise non-conductive panel result in a panel that is electrostatically conductive. Powder particles that are charged with a high positive voltage are then injected toward the panel surface by an air pressure of at least 0.8 kg/cm2 until particles are adhered to the panel surface. The present invention novel method can be used advantageously at low costs due to its simple processing steps and as an environmentally friendly process since no solvent needs to be evaporated and released into the atmosphere. The present invention novel method further provides a low cost method for fabricating flat panel display devices due to its simplified processing steps.
