Abstract: Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.

Abstract: The disclosed tape strip stack is a stack of tape strips arranged one on top of the other for individual removal of each successive tape strip. Secured to a portion of an adhesive on the tape strip, and on alternating ends between successive tape strips, is a tab. The tab protects the adhesive at an exposed tape strip. In some cases, the tab is a removable release tab. Prior to use, the removable release tab is removed, such that a tape strip with an adhesive surface is available for use.

Abstract: The disclosed stack carries individual sheets arranged one on top of the other for individual removal of each successive sheet from the stack. Holding the stack together are individual substrates with an adhesive portion. The adhesive portion on a substrate partially secures to a sheet and partially secures to an underlying substrate on alternating ends of the stack. Therefore, the free end of the sheet can be easily pulled free from the stack, exposing a free end of the next underlying sheet to be easily pulled free from the stack.

Abstract: Crowd funding for innovation includes distributing a proposal with a description of a project idea, an amount of funds requested, and a time frame for raising the funds. Ownership of the project is transferred to an entity, which receives contributions from contributors and for each of the received contributions converts the contribution to a corresponding amount of virtual coin and adds the contribution to the funds. If the funding goal is complete within the time frame, the entity converts the coins to actual money and releases the money to the requestor. After completion of the project, the entity determines if the project is successful and can commercialize successful projects. For certain successful projects, the entity can also distribute funds to the contributors.
