  • Patent number: 6891136
    Abstract: A heating unit is presented for use in a heating device for surface heating of a body to enable maintaining a required temperature of the body. The heating unit is composed of first and second elements each made of a material with a specific resistivity in a range of about 0.01-0.01 Ohm·mm2/m, thereby enabling substantial flatness and flexibility of the heating unit. The first and second adjacent elements are accommodated in spaced-apart planes, are electrically insulated from each other, and have different resistance and different surface areas as compared to each other. The first element having the relatively high resistance and the relatively low surface area serves as a heater, and the second element, which is located closer to the body, when the heating unit is in the operation, serves as a distributor of heat created by the first element when connected to a power source.

  • Publication number: 20040217110
    Abstract: A heating blanket includes a body operable to generate heat from power supplied by two leads. The body includes a support ply having a hole for receiving the lead so that a portion of the body may secure the lead to the blanket and protect the coupling of the lead to the blanket. The body also includes a heating element coupled to a stretchable matt. When the matt is stretched, the heating element stretches in the same direction and can continue to generate heat. Consequently, the body of the heating blanket can maintain sufficient contact with a composite assembly as a contour of the composite assembly's surface changes, and the blanket can adequately cure regions of an assembly that would otherwise be difficult to cure. Because the hole is in the support ply, the support ply reinforces the entire circumference of the hole. Consequently, the portion of the body can protect the coupling of the leads to the body of the blanket through multiple uses of the blanket.

The power source wire is pliable and designed with a connecting point at the rear part for connection of heating plates, a LED indicating power button in the middle and a USB and IEEE1394 plug at the front part. The heating plates use direct current and are secured inside the cloth. A concealed connecting stand is found at the lower part of the electric heating plates for connecting of power source wire. The cloth is made of soft material with adhesive tapes on both sides and apart from the electric heating plates found inside, it is also designed in advance with a side opening.

  • Patent number: 6768086
    Abstract: A warming blanket having a temperature sensing element for sensing the temperature of the warming blanket. The temperature sensor may be a positive temperature coefficient (PTC) element that is threaded throughout the blanket. In one embodiment, the temperature sensing element runs perpendicular or transverse to the heating wires in the warming blanket, permitting the temperature sensing element to measure an average blanket temperature. In another embodiment, the heating element is supplied as a pair of buss wires extending along opposite sides of the warming blanket and having a number of heating wires extending therebetween. In this embodiment, the temperature sensing elements may run either parallel to or transverse to the heating elements. Temperature changes/signals in the temperature sensing element are sent to a microprocessor, which in turn changes the wattage of the heating elements to prevent overheating of the warming blanket.

  • Patent number: 6762395
    Abstract: A heat transfer material comprised of a polymeric material and a nitride or oxide is provided and is thermally conductive, but electrically non-conductive. The polymeric material may be silicone rubber, and the nitride or oxide may be aluminum nitride, boron nitride, silicon nitride, aluminum oxide or beryllium oxide. The material is made flexible by adding plasticizer and remains flexible after an extended period of use. A dielectric jacket for an electrical heating cable is thermally conductive and remains flexible so that it can be reused. The heat transfer material can be used on heating devices such as steam tubes and panels, where the heat transfer material does not bond to or adhere to the heated surface, which allows the heating device to be reused.
