摘要： An improved performance ferromagnetic self-regulating heater. Constant alternating current is applied to a layered structure including at least one ferromagnetic layer. One or more layers of non-magnetic material is added to the ferromagnetic layer in such a way that the power factor of the heater is very significantly increased above its value in the absence of at least one of the layers. The alternating current flows through the different layers in varying quantities depending on layer composition, temperature and Curie point of the ferromagnetic layer. The structure generates heat by resistive heating as a function of the power applied. In one embodiment a single layer of non-magnetic, high-resistance material is in intimate electrical and thermal contact with one surface of the ferromagnetic material. Below the effective Curie temperature of the ferromagnetic layer the current is mainly confined in the non-magnetic layer which heats with greater efficiency due to better resistive and impedance characteristics. In a second embodiment a further non-magnetic, low-resistance layer is added to the opposite surface of the ferromagnetic material. Here the majority of the current is switched from the high-resistance to the low-resistance layer as the heater approaches effective Curie. By these means impedance matching circuit losses can be substantially reduced and energy is saved in high power systems based on the power factor.

摘要： Dans bon nombre de cas il est souhaitable d'utiliser un corps de chauffe flexible autorégulateur pouvant chauffer, sans surchauffer, et en même temps serrer fermement les pièces qu'il entoure. Un exemple d'une telle utilisation est le domaine des câbles de communication blindés. Un tel corps de chauffe autorégulateur comprend une bande flexible, allongée et relativement plate de corps de chauffe autorégulateur (10) possédant un premier organe mince allongé (5) en matériau ferromagnétique et un deuxième organe mince allongé (4) sur le premier organe allongé, possédant une résistivité inférieure à celle du matériau ferromagnétique, un dispositif de verrouillage (12, 14, 16) permettant de serrer la sangle de corps de chauffe autour de la pièce (20) à chauffer, et une source d'énergie constante à courant alternatif (31) développant un courant alternatif dans la sangle du corps de chauffe suffisant pour que sa température s'approche du point de Curie du matériau ferromagnétique.

摘要： A technique for producing soldering iron tips entails cutting clad wire into a plurality of segments, each segment comprising a core of material (such as copper) and an outer protective layer (such as stainless steel, Ni, Cr, or alloy thereof). Each clad wire segment is then shaped into a soldering iron tip by a cold or hot heading process, or other metal forming process. In the finished tip, the protective outer layer is disposed behind the working area of the tip, and serves to reduce the corrosion of the tip, and to improve the electrical conductivity between the tip and the soldering iron handle. A heater element can be formed at one end of the soldering iron tip from the same clad wire segment used to produce the tip itself, thereby ensuring good thermal transfer properties between the heater element and the tip. The invention also pertains to a technique for forming a protective outer layer on the working area of the tip. The technique comprises stamping caps from a thin strip or sheet of protective material, such as iron. More specifically, the caps are stamped out of the sheet using a die having a shape which resembles the shape of the working area of the soldering tip. The caps formed in this manner are then inserted over the ends of the tips, and attached thereto by applying brazing material to the formed cap or to the strip of material prior to forming the cap.
摘要翻译：用于生产烙铁头的技术需要将包覆线切割成多个节段，每个节段包括材料（例如铜）的芯和外部保护层（例如不锈钢，Ni，Cr或其合金）。然后通过冷或热镦锻工艺或其他金属成形工艺将每个包层线段成形为烙铁头。在完成的尖端中，保护性外层设置在尖端的工作区域后面，并且用于减少尖端的腐蚀并且改善尖端和烙铁手柄之间的导电性。加热器元件可以形成在烙铁头的一端与用于产生烙铁头本身的同一包层线段相连，由此确保加热器元件和烙铁头之间良好的传热性能。本发明还涉及在尖端的工作区域上形成保护性外层的技术。该技术包括从薄片或片材如铁等保护材料上冲压盖帽。更具体地说，使用具有与焊接头的工作区域的形状类似的形状的模具，将盖帽从薄片上冲压出来。然后将以这种方式形成的盖帽插入尖端的端部上，并且在形成盖帽之前通过将钎焊材料施加到成形的盖或材料条上而将其连接到其上。

摘要： A tweezer-like heater structure includes a pair of arms that are pivotable towards one another and a pair of legs having ferromagnetic temperature self regulating Curie point heaters at the ends of the legs, the legs being removably connectable to electrical connectors located in the arms whereby current is supplied to coils that energize the heaters. Heaters of different temperatures may be provided by choosing heaters with ferromagnetic materials having different Curie temperatures. The structure may be used as a soldering iron by inserting a heater with a proper shape in one arm and short circuit the connector in the other arm.

摘要： The invention provides a system and method for joining plastic members including induction heaters fabricated from a conductive wire coated with a ferromagnetic material and providing ratios of at least 4 to 1 between the areas over the spaces between wires and the area of the wires surrounding the open spaces; the heaters being located preferably between plastic members to be joined. The heaters may be located adjacent the two ends of a plastic connector adapted to receive a pipe in at least one and probably two ends with the heaters being activated preferably by induction heating to produce welding of the plastics to one another. One form of heater is fabricated on a hollow cylindrical mandrel having helical grooves in which the wire is wound and having radial holes arranged in axially extending rows spaced circumferentially about the mandrel so the axially extending wires may be spot welded to the wires in the helical grooves at each hole. Rings of wire may also be held together by axially extending grooves. Saddle fittings and patches may also be applied to pipes or other plastic members employing such heaters. Induction coils in the form of clamshell and jaw-like structures may be employed as appropriate to energize such heaters and flexible coil structures may also be employed.

摘要： Solenoid coils are provided that produce relatively low irradiation of electromagnetic fields with intense fields internally thereof for purposes of heating a metallic element, preferably a ferromagnetic element having a Curie temperature selected for the purpose for which the coil structure is to be employed, the coil structure in one embodiment comprising two coaxial coils of substantially equal diameter interconnected to produce in response to an alternating current being applied thereto out of phase magnetic fields that do not substantially interfere with one another as a result of the spacing between the coils. In a second embodiment the two coils are located between two additional coils that buck axial fields thereby together with fall off of the fields as the cube of the distance from the main coils provide a structure with low external radiation. The method of forming the first coil structure includes winding a pancake coil in the form of a spiral, rotating out of the plane of the coil the innermost leg of the spiral to provide the desired spacing of the coils, forming the pancake into a cylindrical shape with the cross members of the pancake being laid one over the other to provide cancellation of the fields produced by these members.
