摘要： A visual display including a container, liquidous fluid within the container, a source of gaseous fluid communicating with the liquidous fluid, and at least one binary bubble formed within the liquidous fluid in response to gaseous fluid entering the liquidous fluid. The liquidous fluid is preferably a polymer in water solution or a polymer in mineral oil or silicon oil solution. The binary bubble has two bulbous portions in fluid communication with each other through a neck. The binary bubbles may link together in a chain extending from the bottom of the container to the top of the liquidous fluid. In other constructions, the binary bubbles float up through the liquidous fluid and collapse into a large individual bubble. The display may also include a light emitting source and a filter for selectively changing the color of light emitted into the container.

摘要： A positioning tool for use in attaching the cover panels to support members in a prefabricated building system using self-drilling and self-tapping fasteners and a locking member which includes locating means for positioning the locking member behind the overlapped cover panels and guide means for locating the fastener against the support member opposite the locking member so that the fastener is aligned with the locking member and, as the fastener is installed by self-drilling and self-tapping its way through the juxtaposed support member and cover panels, the locking member will be threadedly engaged by the fastener to hold the cover panels against the support member between the head of the fastener and the locking member.

摘要： A fastener assembly for use in attaching cover panels to support members in a prefabricated building system where the cover panels and support members have a prescribed total thickness at the point of attachment including a self-drilling and self-tapping screw where the self-tapping thread on the screw terminates a prescribed distance from the head of the screw which is substantially equal to the total thickness of the support member and cover panels so that the screw will self-drill and self-tap its way through the support member and the cover panels and the self-tapping thread will release the support member nd the cover panels when the head on the screw is seated against the support member so that the screw is free to rotate with respect to the support member and cover panel; and a locking member adapted to be threadedly engaged by the screw behind the cover panels to clamp the cover panels onto the support member between the locking member and the head of the screw.
摘要翻译： 一种用于将盖板附接到支撑构件的预制构筑系统中的紧固件组件，其中盖板和支撑构件在附接点处具有规定的总厚度，包括自钻孔和自攻螺钉，其中自攻螺纹 在螺钉上从螺钉头部终止规定的距离，该距离基本上等于支撑构件和盖板的总厚度，使得螺钉将自行钻孔并自动地将其穿过支撑构件和盖板 当螺钉上的头部靠在支撑构件上时，自攻丝将释放支撑构件和盖板，使得螺钉相对于支撑构件和盖板自由旋转; 以及锁定构件，其适于通过所述盖板后面的所述螺钉螺纹地接合，以将所述盖板夹紧到所述锁定构件和所述螺钉的头部之间的所述支撑构件上。
