Holographic Technology Offers Robust Authentication

A new security technology provides a hologram invisible to the naked eye. The tool requires viewing with a prism to discover the holographic image. The product also supplies a primary and complementary hologram for applications where visibility is required or desired. Both approaches offer robust authentication and are extremely difficult to counterfeit. The technology is suitable for high-volume production.

Heat-Seal Adhesive

A new food-grade heat-seal adhesive is needed for roll-coated film lids. New chemistries must be formulated into a waterbased matrix to seal transparent film onto plastic trays containing food or medical materials. The organization deals primarily with polyester films (APET/CPET) and trays, and containers made from polystyrene (PS), polyethylene (PE), polypropylene (PP), polyester (PET), and polyvinylchloride (PVC). Extrusion films or solvent-based materials are not needed, and the solution must withstand 100–140 °C during application. Because the substrate is roll-wound, the material cannot adhere to itself at room temperature.

Corrugate Reduction

An organization wants to use less corrugate in its shipping operations. Unique designs or processes must reduce the amount of corrugate material required, while maintaining the same level of protection for the products being shipped. Replacing corrugate with another material may be considered, but the replacement material will have to be less expensive and equally environmentally friendly. Possible solutions include thin-walled corrugate, fewer pieces, corrugate reinforced with 90-degree-angle folds, or corrugate in combination with shrink-wrap. The proposed method must be automated and cannot increase the labor component of packaging the materials.

Gauge Calibrates Three-Dimensional Coordinate Measuring Machine (CMM)

A gauge, which is used in examining the accuracy of a coordinate measuring machine (CMM), enables total calibration of errors and numbers of revisions of the measured values. The accurate calibration is possible for a CMM of any size. Various machines can also be calibrated by combining the gauge.

Inspection Technology Identifies Surface Defects

An automated surface inspection technology identifies potential defects on a painted surface so that they can be remedied. The system provides a database so that the size, location, quality, and other aspects of production line defects can be tracked over time.

Razor “Saws” Hair for Easier Shaving

With traditional razors, the cutting edge of a blade moves in the direction of the cut. A new shaving device, however, includes one or more blades that perform a vibrating motion perpendicular to the direction of the cut, and parallel to the blade’s edge; the hairs are cut by sawing, rather than cutting.

Medical Valves Withstand Magnetic Fields

Parker Hannifin has created design concepts for valves that can be used in MRI-compatible ventilators. The valves, built to work with a variety of medical fluids and gases, are unaffected by strong magnetic fields and, in turn, do not create any magnetic fields of their own. In addition, the valves can be designed to handle a range of operating characteristics while minimizing total footprint.
