| 219532000 | With open frame or grid-type support | 10 |
| 20090026194 | Method of Manufacturing an Electric Heating Device and Electric Heating Devices - An electric heater, comprises a heating block held in a housing and including parallel layers of heat-emitting and heat generating elements. A grid arrangement covers the respective frame apertures in the housing and reinforces the housing. First struts of the grid arrangement, extending at right angles with respect to the layers, are assigned to the housing, and second struts extending parallel with respect to the layers are defined by the heating block. Moreover, a heat generating element of an electric heater, comprises a position frame made of an insulating material and defining receptacles arranged side by side each for at least one PTC heating element. The receptacles are arranged between conductor paths against which the PTC heating elements are placed in an electrically conductive manner. | 01-29-2009 |
| 20090139984 | Open coil electric resistance heater with offset coil support and method of use - An open coil electrical resistance heater uses a number of offset insulators to support the coil of the heater. The offset insulators configure the run of coil in a sinusoidal shape to hold the insulators in a more secure manner and reduce vibration and noise generation during heat operation. The sinusoidal configuration of the coil also reduces the problem of shadowing of portions of the resistance wire coil. | 06-04-2009 |
| 20090139985 | Multiple stage open coil electric resistance heater with balanced coil arrangement and heater cool end termination and method of use - A multiple stage open coil electrical resistance heater uses a unique coil configuration on either side of a dividing support plate so that the air passing through the heater is heated uniformly when one or more stages of the heater are energized. The coil configuration also creates a termination zone on one side of the heater so that the terminations of the coils can be situated on the cool side of the heater. The heater coils also includes specially configured terminals to facilitate connection to power using an elongated member such as a stud or bolt. | 06-04-2009 |
| 20090188908 | SUPPORT FOR AN ELECTRICAL HEATING DEVICE, ELECTRICAL HEATING DEVICE AND METHOD FOR THE MANUFACTURE OF AN ELECTRICAL HEATING DEVICE - An electrical heating device has an integrally manufactured support made from insulating material. Depressed paths for introducing a heating element are provided. A klixon functioning as a thermally actuated switch is inserted from above into an opening in the central area of the support and its electrical terminals project over the bottom side and are bent round for mechanical fixing. | 07-30-2009 |
| 20100059504 | OPEN COIL RESISTANCE HEATER WITH RIGHT AND LEFT HAND INSTALLATION CAPABILITY - An open coil resistance heater assembly is made for universal mounting between left and right hand installations in an appliance or other equipment. The heater assembly has its coils arranged symmetrically about a bisecting plane of the heater assembly and/or a center line of its terminal assembly aligned with the bisecting plane. The symmetrical coil arrangement and/or bisected terminal assembly allow the heater to be used in right hand or left hand installations. | 03-11-2010 |
| 20110062144 | CERAMIC HEATER AND METHOD FOR MAKING THE SAME - A resistive heating element | 03-17-2011 |
| 20110132896 | HEATER PLATE WITH EMBEDDED HYPER-CONDUCTIVE THERMAL DIFFUSION LAYER FOR INCREASED TEMPERATURE RATING AND UNIFORMITY - A heater plate is constructed with an embedded thermal diffusion layer of pyrolytic graphite to provide increased temperature uniformity in a critical heating surface. The heater has first and second metal plates with a heater element contained within the first plate and a core of the pyrolytic graphite diffusion layer sandwiched between the heater element and the second metal plate. The diffusion layer may be sputter metal coated to improve bonding of the layer to the plates. | 06-09-2011 |
| 20110315673 | SUPPORT STRUCTURE FOR HEATING ELEMENT COIL - Spacer for a vertical support structure of a heating element coil includes a mating feature including complimentary components on first opposing sides of the spacer, a cavity, open to second opposing sides of the spacer, and an extension offset from an axis intersecting the mating features, the extension including a pocket sized to fit an individual loop of the heating element coil. The spacer can be incorporated into a support structure for a heating element coil interlocking adjacent loops of the coil so that they are retained in a collinear and concentric arrangement while allowing the loops of the coil to move freely inward and outward from the central axis in unison. | 12-29-2011 |
| 20160377300 | METHOD AND APPARATUS FOR POSITIONING HEATING ELEMENTS - An underlayment system is provided that includes a plurality of bosses that emanate form a common base member. The bosses and bases preferably include an opening therethrough that will allow for subsequent layers of adhesive to interact and bond to each other. The bosses are also spaced in such a way to help secure a wire snugly therebetween. | 12-29-2016 |
