Abstract: A method for processing prickly pear cactus skeletons and the resulting article. The process produces stabilized, acid and mold-free planer or three-dimensionally formed, cactus skeletons that can be easily handled. The method of the present invention preserves and enhances the natural intricate and delicate vein-like structures of the native skeleton and effectively alters the natural pH to a highly non-acidic state. Prickly pear cactus skeletons processed by the inventive method are ideally suited to be used as, or incorporated into, museum quality frame matting.

Abstract: A bi-stable snap action ribbon spring incorporated into self-latching, spring-loaded mechanisms. The dual mode stability of the spring eliminates the need for complex latching mechanisms thereby simplifying the device manufacture and device reliability. The spring is stable in either a linear or coiled state enabling the simplified design of rolling, hinging and feeding mechanisms. A plan or map rolling and presentation device incorporates a bi-stable snap action ribbon spring along with optional spring end caps and stiffening elements. The plan or map is driven to a stable coiled or stable rolled shape by the influence of the snap action spring. Application of the snap spring properties to a discreet length of a longer ribbon can create a hybrid bi-stable hinge mechanism. A convenient storage container utilizes the bi-stable characteristics of a snap action ribbon spring to create a container having a self-closing and captured lid.

Abstract: A device providing an improved method for the storage and releasable attachment of a focusing straw onto an aerosol can. In a preferred embodiment, the device is a commercially available cable-tie, modified to provide a releasable attachment and reliable storage of a focusing straw onto an aerosol can. A method of the present invention allows a user to modify an existing cable-tie to provide releasable attachment of a focusing straw onto an aerosol can or other item. The availability and subsequent use of a focusing straw often reduces aerosol over-spray and the resultant air borne contamination. Use of the present invention has, in some cases, reduced the consumption of aerosol spray oil by 30%.
