摘要： A sign opening, closing and locking device for use on a conventional rectangular, box-like sign having one or more advertising panels hingably attached to the frame. The device comprises gear racks and pinion, a raceway for containing the racks, linkage from the racks to the front panel, and a crank for rotating the pinion. In operation the crank is mated with a shaft to rotate the pinion. Rotation of the crank and the engaged pinion cause linear movement of the racks and the attached linkage resulting in an initial disengagement of the linkage from a stationary lock pin. Further rotation results in an outward movement of the front panel as it is rotated on its hinges. Opposite rotation of the pinion results in closure and locking of the sign.
摘要翻译：一种用于常规矩形盒状标志的标志打开，关闭和锁定装置，其具有可铰接地连接到框架的一个或多个广告面板。该装置包括齿轮和小齿轮，用于容纳齿条的滚道，从机架到前面板的连接以及用于转动小齿轮的曲柄。在操作中，曲柄与轴配合以旋转小齿轮。曲柄和啮合的小齿轮的旋转引起齿条和所连接的联动装置的线性运动，导致联动装置与固定的锁定销的初始脱离。进一步的旋转导致前面板在其铰链上旋转时的向外运动。小齿轮的相反旋转导致符号的关闭和锁定。

摘要： A process for making a laminated wood product includes sawing or sanding opposite faces of offcut wood strips, to prepare these faces for glueing with the strips in quartersawn orientation. The strips are also prepared by sanding or planing substantially parallel to the top and/or bottom surfaces of the strips. The strips are glued end-to-end and side-by-side to form a laminated plank having the strips in quartersawn orientation. The plank is finished to form a laminated quartersawn strip product which may be used for flooring, paneling, millwork or other purposes.
