Patent number: 8786397Abstract: An electric field resistor includes N coils. N coils encircle a common center in sequence, and each of the coils has a first terminal and a second terminal, wherein the first terminal of the first coil receives a first reference voltage, the second terminal of the Nth coil receives a second reference voltage. The second terminal of the ith coil is coupled to the first terminal of the (i+1)th coil, wherein N is a positive integer greater than 1 and 1?i<N. Besides, a distance between the ith coil and the (i+1)th coil is in direct proportion to a voltage difference between the first terminal and the second terminal of the (i+1)th coil.Type: GrantFiled: February 7, 2013Date of Patent: July 22, 2014Assignee: Excelliance MOS CorporationInventors: Chin-Chieh Li, Hung-Che Chou, Pao-Chuan Lin

Patent number: 5910266Abstract: The invention is in the field of electrical resistance heaters, especially heaters for tubes, pipes, or flexible hose. More particularly, the invention is directed to an electrical heater formed as a strip that is permanently set in the shape of a helix. According to an aspect of the invention, an electrical heater is provided comprising a flexible electrical insulation strip bounded by a first longitudinal edge and a second longitudinal edge, wherein the flexible electrical insulation strip is permanently set as a helix such that the first longitudinal edge is adjacent to the second longitudinal edge; and, a flexible electrical heating element encapsulated within the electrical insulation strip.Type: GrantFiled: May 28, 1997Date of Patent: June 8, 1999Assignee: The B.F. Goodrich CompanyInventor: Darryl W. Jones

Patent number: 4754124Abstract: A resistance heater for performing heat treatment of the braze-affected area of a metallic sleeve attached by brazing within and to a metallic tube, comprises a metal tube (10) of which a portion (16) is formed with a spiral groove (11) which penetrates the wall thickness of the tube (10) and thereby defines a heating coil. The radial thickness of the convolutions of the coil varies lengthwise of the coil so that, when energized with electrical current, the coil develops a temperature profile which is determined by the variation in radial thickness. The temperature profile may be selected according to the needs of the brazed joint to be heat treated.Type: GrantFiled: March 2, 1987Date of Patent: June 28, 1988Assignee: United Kingdom Atomic Energy AuthorityInventors: Robert G. Howell, Malcolm Stevens

Patent number: 4668855Abstract: A support for an electric heating element comprises a former of generally cylindrical shape, made of a heat resisting material and having a longitudinal core from which extend spaced ribs that support an outer wall. Portions of the outer wall and of the ribs are omitted along a helical path around the core to provide a mount for an electric heating element. A heating element assembly including the support and the heating element is mounted in a hot air gun.Type: GrantFiled: June 19, 1985Date of Patent: May 26, 1987Assignee: Black & Decker Inc.Inventors: Peter H.

Patent number: 4247842Abstract: This specification discloses a cut-in resistance for motor vehicle heating fans with a first resistance wire winding which can be cut into an electric fan motor either alone or in series with a second resistance wire winding. The first winding is arranged in the interior of a ceramic tube and the second winding is arranged on the outside of the ceramic tube. The ceramic tube is retained solely by the ends of the resistance wires which are passed upwards to a ceramic plate and clamped by flat plug contacts. This produces a compact arrangement wherein the ceramic material can safely store generated heat without danger of heat damage to adjacent plastic components.Type: GrantFiled: September 6, 1979Date of Patent: January 27, 1981Assignee: Ford Motor CompanyInventors: Helmut Bengsch, Alfons Link
