Abstract: A versatile multiple spout balloon network is provided with thin walled, resilient, single or multiple spout balloons which may be interconnected to other balloons or a pole using plugs. Plugs provide for resilient and airtight engagement of balloons at their spouts. Plugs may include an air channel for passage of air between balloons and the network. The network may include one or more poles, each pole having several branches. Balloons may make an airtight and resilient engagement with the poles at branches using a plug. A stand may be used to erect the plug pole by inserting the pole into a fitting hole in the middle of the stand. A plug unit may comprise multiple surfaces attached to, or integrated at, a central point in different patterns.

Abstract: The paper clips of the present invention are more gradually curved to have a substantial lateral extent, so that they will hold a much thicker stack of papers without deformation or buckling, as compared with the standard narrow sharply curved paper clips. More specifically, when a predetermined length of wire is employed, the clips have a ratio of the predetermined length to the width, and to the height of the clip, of between about 4 and 6. In addition, where one end of the wire is arranged to engage a stack of papers on one side and the other end of the wire is arranged to engage the stack of papers on the other side, at a point between the two ends there is a gradually curved portion corresponding generally to one-half the circumference of a circle having a diameter in the order of the transverse dimension of the clip.
