Abstract: A method implemented by computer-networks comprises the following steps: creating a mutual aid group capable of accommodating a plurality of small businesses using programming codes by assigning values to its attributes including the attribute on the shares which the prize offered by the mutual aid group is divided into; and storing the created mutual aid group in a mutual aid group storage area in a database; and recruiting at least one business into the mutual aid group by the businesses subscribing for the share of the mutual aid group for jointly running a prize promotion; and running the collective promotional campaign through the mutual aid group for all the members having joined the mutual aid group to produce winners; and controlling the running process of the mutual aid group including the process of grouping the businesses, the process of running the collective campaign, and the transformation of these processes. A system based on the computer-networks supports the implement of the above method.

Abstract: A combinable-free ornamental device, it is a basic unit to create more complex, nice looking decorative patterns. The ornamental device is a flat body of material, and its front surface is decorated with surface ornamentation, such as a relieveo, a painted pattern, etc. to add to its visual appeal, and its back is planar, or at least the edge of the back is in an identical plane, so that the ornamental device can be secured to the ceiling, or the wall, or a similar surface, and it has a predetermined shape with at least one arc edge, and the shape of its main body is symmetrical.

Abstract: A measuring instrument for bay windows is primarily comprised of a left wing and a right wing, and the two wings are joined together by a rivet, and each of them can rotate around the rivet, and each has a straight topside. There are three sets of scale line respectively for the angle, the width and the interval on a surface of the two wings. In which, the interval lines is the most important, and they are a set of parallel lines parallel to the topside to indicate the interval to the topside. The two straight topsides can form an included angle by the rivet as a vertex. The two topsides and each pair of corresponding interval lines can align when the included angle is 180°, but each pair of the corresponding interval lines intersect when the included angle is less than 180°. Make width an indicating line pass through an intersection of some pair of corresponding interval lines, and it can just point out according width value.

Abstract: A device to make and keep natural waved pleats for a drapery is comprised of a long thin flexible matter and some linkups. The long flexible matter may be a chain, and it may be a rope too, etc, and a linkup may be a keyring, a buckle or a tie, etc. The linkup may be fixed at any position of the long flexible matter. Generally, the drapery is comprised of a fabric, hooks, slide matters and a rod. The fabric is hanged into the slide matters with the hooks, and the slide matters can slide along the rod. So, we can draw the drapery by moving the slide matters. If we arrange the slide matters at equal interval along the rod and join the long flexible matter to the slide matters with the linkups correspondingly, and the equal interval between the slide matters be controlled by the device. With the device, the drapery with wider fabric than the rod should not become plane, but lively and finished with the natural waved pleats.
