| 20120128494 | VARIABLE PERFORMANCE VANEAXIAL FAN WITH HIGH EFFICIENCY - The design of a high efficiency, variable performance vaneaxial fan, requires the utilization of typical fan and single stage compressor design methodologies. To be able to replace multiple fans, the variable vaneaxial fan design must be capable of operation at several different flow rates and total pressures. These operation points can be met by varying motor revolutions per minute (RPM) or geometric parameters such as the hub diameter, tip diameter, as well as blade geometry including number of blades, pitch, spacing, and length. An ideal design with variable performance can replace a family of current fan designs by providing the capability for efficient operation over a range of flow rates and total pressures. This level of variability would not only allow the fan to respond to changing environmental conditions but also to be fit into systems with different characteristics. | 05-24-2012 |
| 20110282022 | SHAPE MEMORY POLYMERS FORMED BY SELF-CROSSLINKING OF COPOLYMERS - The present discovery shows how to make a self-crosslinking SMP. Shape Memory Polymer (SMP) can be formulated as a castable coating. This process allows the polymer to dissolve in solvent, and as the solvent evaporates the polymers self-crosslink at room temperature in air, creating a copolymer coating wherein the copolymer coating is an SMP. This technology has coating applications where shape memory would be an asset: from shape memory textile and fabric to self-healing coatings for vehicles and morphing skins for aircraft. | 11-17-2011 |
| 20110265292 | QUIET RELEASE SHAPE MEMORY POLYMER FASTENERS - Disclosed herein is a process for engaging and disengaging a releasable fastener system, comprising fastening devices composed of elastomers or shape memory polymers and their composites wherein the fastening devices may be of any number of geometrical shapes limited only by the fact that each pair of fastening devices are designed such that the mating geometries of each device are compatible with one another. This disclosure relates to an apparatus and process for an easy and near silent closure mechanism for a container. Specifically this application deals with the use of elastomers or shape memory polymers as the connection devices in a fastener system which can be used to attach one part to another or act as the closure mechanism for a pocket, box, or other container. | 11-03-2011 |
| 20110178247 | EXTRUDABLE SHAPE MEMORY POLYMER - The presently disclosed formula utilizes a composition of a rigid, semi-crystalline polymer, such as polybutylene terephthalate, and an amorphous polymer, such as poly(vinyl acetate), to create a thermoplastic shape memory polymer that can be processed through methods such as extrusion and injection molding, which require high heat. The polybutylene terephthalate acts as a cross-linker for the poly(vinyl acetate), therefore the thermoplastic shape memory polymer that is created has a much higher melting point and greater heat stability than other shape memory polymers. | 07-21-2011 |
| 20110084174 | PASSIVE ADAPTIVE STRUCTURES - Morphing an aerodynamic body's geometry in situ can optimize its aerodynamic properties, increasing range, reducing fuel consumption, and improving many performance parameters. The aerodynamic load exerted on the body by the flow is one such parameter, typically characterized as lift or drag. It is the aim of the present disclosure to teach the use of passive adaptive morphing structures to manage these aerodynamic loads. | 04-14-2011 |
| 20100229610 | Locking Device Using Shape Memory Materials - The disclosed devices use shape memory materials, and specifically shape memory polymers and composites to allow or disallow mechanical or physical movement. By positioning the shape memory polymer so it is near the mechanical device which is to be moved, the shape memory polymer will allow or disallow the motion of the mechanical device depending on the state the shape memory polymer is in. When the shape memory polymer is in its hard rigid state the device cannot move. Once activated the shape memory polymer will become soft and pliable, whereupon with sufficient force the mechanical device can be moved to a new position. Once in this new position the SMP can either remain in its relaxed state, the SMP can return to a hard rigid state and maintain its deformed shape, or the SMP can return to its original shape to ensure the device does not move. | 09-16-2010 |
| 20100221523 | METHOD OF MAKING AND USING SHAPE MEMORY POLYMER PATCHES - A method of repairing a composite component having a damaged area including: laying a composite patch over the damaged area; activating the shape memory polymer resin to easily and quickly mold said patch to said damaged area; deactivating said shape memory polymer so that said composite patch retains the molded shape; and bonding said composite patch to said damaged part. | 09-02-2010 |
| 20100196705 | METHOD OF MAKING AND USING SHAPE MEMORY POLYMER COMPOSITE PATCHES - A method of repairing a composite component having a damaged area including: laying a composite patch over the damaged area; activating the shape memory polymer resin to easily and quickly mold said patch to said damaged area; deactivating said shape memory polymer so that said composite patch retains the molded shape; and bonding said composite patch to said damaged part. | 08-05-2010 |
| 20090095865 | Device for Securely Holding Objects in Place - A device utilizing the unique properties of shape memory materials to securely hold items of varying geometric shape and size securely in place is disclosed. This device and process works equally well for securely holding in place small items, such as would be stored in a cup holder, or for securely larger items in a cargo container. By deforming the shape memory material such that it conforms to the outer dimensions of the item to be held in place a secure and tight fit is assured. | 04-16-2009 |
| 20080315466 | High Speed Manufacturing Using Shape Memory Polymer Composites - Structurally strong composites are formed with shape memory polymer resins to create composites with shape memory properties. A system and method for using these composite structures to quickly manufacture composite products involves: 1) creating a preform composed of a shape memory polymer composite; 2) heating or otherwise activating the shape memory polymer; 3) using a mold to deform the composite material to a desired shape; 4) cooling or otherwise deactivating the shape memory polymer so that the composite structure retains the desired mold shape. | 12-25-2008 |
