摘要： A method for bonding or joining thermoplastic or thermoset polymeric materials is provided which comprises applying a layer of conductive material (16) at a joint or between surfaces of thermoplastic or thermoset polymeric materials (12, 14), introducing a current so as to raise the temperature of the polymeric material above its melting point, maintaining the current for a time sufficient to allow the polymeric material to become molten and thereby form the joint or bond, and then removing the current and allowing the joint or bond (15) to cool. The method is advantageous in that it provides a simple and inexpensive means of bonding thermoplastic or thermoset polymeric materials with a minimum of materials and equipment The method of the present invention can also be utilized so as to heat thermoplastic pipes and other devices made of thermoplastic materials.

摘要： A method for bonding thermoplastic substrates is provided. A thin, porous, resistive heater is provided between layers of thermoplastic substrates to be bonded in the absence of an adhesive. The fabric heater is in intimate contact with the substrates at the joint by application of pressure. When the heater is energized, the thermoplastic material at the joint is melted or softened, and becomes uniformly distributed in the weld. After cooling, the fabric heater remains within the weld area and provides increased reinforcement to the weld bond.

摘要： A heated container is formed from a substantially continuous element structure. The substantially continuous element structure includes an electrically insulative first and second polymeric layers and a resistance heating layer laminated between the first and second polymeric layers. An interior surface of the container includes the first polymeric layer, and the first polymeric layer is thermally conductive. The resistance heating layer has a pair of terminal end portions that may be coupled to a pair of external power leads to energize the resistance heating layer.

摘要： A heating element assembly in the form of a heating shelf and a method of manufacturing heating shelf assemblies. The heating shelf may be used in display cabinets to heat ready made foods such as cookies, muffins, donuts, pizza, sandwiches and the like. The preferred heating shelf includes thermochromic materials, or an LED indicator, which provide a visual indica of shelf temperature. The preferred heating shelf provides intimate contact with the heated food products, thus optimizing heat transfer between the heating shelf and the food products. Optionally provided, varied surface watt density in the heating shelf allows for accurate heat placement such that the food products can be evenly warmed while avoiding over warming. In another embodiment, the heating shelf includes two resistance heating elements. The first heating element is a temperature booster used for defrosting and heating, while the second heating element is a maintenance heater to maintain heated food at a serving temperature.

摘要： Methods of facilitating the adhesive bonding of various components with variable frequency microwave energy are disclosed. The time required to cure a polymeric adhesive is decreased by placing components to be bonded via the adhesive in a microwave heating apparatus having a multimode cavity and irradiated with microwaves of varying frequencies. Methods of uniformly heating various articles having conductive fibers disposed therein are provided. Microwave energy may be selectively oriented to enter an edge portion of an article having conductive fibers therein. An edge portion of an article having conductive fibers therein may be selectively shielded from microwave energy.

摘要： Forming a novel double containment polymeric piping assembly by interfitting slidably interfittable polymeric inner pipe components, including a first induction responsive layer therebetween, and slidably interfittable polymeric outer pipe components, preferably including a second induction responsive layer therebetween, to form an inner connection and an outer connection, while causing the inner connection to be axially offset from the outer connection, applying an electrical induction force around the periphery of the outer pipe components, axially aligned with the inner connection but not with said outer connection, and thereby fusing the inner pipe components and the first polymeric layer together, and moving the components relative to said electrical induction force, axially away from the inner connection, and axially aligned with the outer connection, applying an inductive force around the periphery of the outer pipe components, and thereby fusing the outer pipe components and the second polymeric layer together.

摘要： A fixed coil induction heater produces quality thermoplastic fusion welds in prefabricated resin composite parts. A susceptor along a bondline between parts aligns with the induction coil segments of a solenoid induction coil along the centerline of the coil. Energizing the coil heats the susceptor to form the weld at the bondline. For this operation, our induction heating workcell uses complementary dies that define a central cavity with an oval pattern of induction coil segments roughly conforming to the shape of the cavity and surrounding all faces of the cavity where we position the preform composite parts and susceptor.
