An adhesive shearing strength between surface layers test method is a method for effective evaluation of the shearing strength of adhesive materials between surface layers, especially an easier solution whose test mode is also easier of the current problem that the shearing strength of adhesive materials between surface layers is inaccurately tested because of a unreasonable loading method. This method has the following steps: 1. indoor test: step one, preparing a sample and fixing the sample; step two: starting a motor and do a twisting and shearing test; step three, collecting and analyzing data. 2. Field test: step one: drilling a core of the surface layer, but not taking it out, and then drying the upper surface of it with hot wind; step two, bonding a shearing test fixture head and a core sample together; step three, implementing a twisting and shearing test after 30 minutes; step four, collecting and analyzing the data.

Convenience stores are provided a beverage water processor for coffee and beverages. The “ideal” total dissolved solids (TDS) of perhaps 110 parts per million is achieved without a blendback process. The R / O water is remineralized with a flow through calcite bath. A potassium chloride source is used to inject the exact amount of potassium chloride needed to reach the ideal TDS on the fly before the water reaches the storage reservoir. Alarms trigger a bypass loop to keep the store in business during shutdown. All output water passes through a UV sterilizer.

A flexible hurricane shutter or barrier to protect buildings from over pressure has inflatable cushions held in place by a fabric material capable of withstanding winds in excess of 100 mph. The barrier can be stored on site in a rolled fashion. Retainers are mounted on a building to guide and secure the longitudinal edges of the fabric to permit ease of deployment. The retainers may be spaced apart over one side of a building and the barrier may be deployed over an entire surface of a multi-story building by raising and lowering the fabric. Inflatable cushions are held between the fabric and the building. The inflated cushions reinforce the material and distribute the force of impact throughout the surface of the cushions and act as spacers to both hold the fabric off the structure and focus the forces onto stranger portions of the structure.
