Abstract: An improved support is provided for locating a lamp filament axially within a lamp sleeve. The illustrated support is a spiral coil that includes a small diameter center portion that makes contact with the filament. On either side of the filament-contacting portion, the coil opens up to larger diameters for contacting the inner wall of the quartz sleeve within which the filament is housed. The support thus appears H-shaped when viewed from the side. A lamp filament is also provided with expansion compensation sections at either end of a central section. The filament wire in the compensation sections is wound into coils having a greater diameter and also a greater spacing between windings, as compared to coil in the central section. The expansion compensation sections are preferably capable of compressing and thereby absorbing thermal expansion of the filament during operation, without shorting the filament across adjacent windings.

Abstract: An electric heater for industrial liquids comprises a plastic flat box that contains a stainless steel pressure vessel holding a number of parallel electrical heating rods. These heating rods are interlaced with shorter “I” shaped Teflon rods which generates a tube-like space around the heating rods. Spiral grooves in the symmetrical concave faces of the Teflon rods promote a spiraling turbulent flow. The general liquid flow from the liquid inlet meanders around the parallel heating rods for optimal heat transfer. The heater can be mounted horizontally or vertically on the side of a lab bench or a vessel for floor space conservation. The flow speed of the liquid, its specific heat, the number of heating elements with their individual power rating determine the heating profile of liquid temperature versus cumulative length of the flow path which is important to prevent the liquid from reaching the boiling point. This arrangement allows for design flexibility and scalability in heating capacities.

Abstract: Information handling system peripherals that use a heating element are protected from catastrophic failure due to overheating by a thermal failsafe associated with the heating element that fails the heating element if excessive temperatures are reached. For instance, the failsafe releases the vacuum from a heating element bulb so that the application of power to the filament of the heating element bulb oxidizes the filament resulting in failure of the filament and ceasing of generation of heat. The failsafe includes a melting agent, such as wax or solder, which seals an opening in the bulb unless a thermal runaway temperature is reached in excess of a desired operating temperature. Alternatively, the failsafe includes an expanding agent, such as a ceramic or a liquid-filled bubble, which releases the vacuum by fracturing an opening in the bulb at the thermal runaway temperature. The thermal runaway temperature is selected to induce failure before catastrophic overheating of the peripheral.

Abstract: A sheathed electrical resistance heater is provided with a metal corrugated resistance heating element located internally within a surrounding metal sheath and separated from the sheath by a compacted insulating material such as magnesium oxide. The preferred corrugated resistance element is a flat strip of metal that has been corrugated such as by passing the strip through the nip of a pair of gears. The corrugated strip resistance element is thicker than a foil and may be used to provide sheathed, electrical resistance heaters where it is too difficult to wind large diameter wires, which are desired for a low resistance ohm of 0.12 ohm/inch or less, on a small arbor to form a coiled wire resistance element. A heater may be formed with a resistance of 0.05 ohm/inch using the corrugated metal ribbon and may be 200 inches in length and have a finned sheath. Preferably, the sheath is compressed in a die to reduce the cross-sectional area of the heater without a substantial elongation of the sheath.

Abstract: A large area heater used, for example, in a laser printer belt fuser or as cooking surface, has an alumina substrate in which two bowed parts of alumina ceramic having opposed concave regions are formed together as a laminate. Electrical resistors are deposited on the laminate. The alumina laminate provides excellent resistance to uneven heating or other thermal stress. Alumina ceramic is readily shaped during manufacture and manufacturing costs and yield are good. A wide variety of large area heaters can usefully employ the laminate.

Abstract: An electrical heater utilizes negative temperature coefficient material (NTC) and current imbalance between live and neutral ends of the heater to simultaneously protect the heater from the hot spot and mechanical intrusion into the heating cable. The NTC layer, separating the heating wire and current leakage conductor, becomes electrically conductive at the temperatures above 60° C., thus “leaking” the current to earth. The hot spot is detected by measuring the current imbalance between line and neutral connections of the heating cable. The mechanical intrusion into the heater, such as cable or insulation damage, water or sharp metal object penetration, is also simultaneously measured by the same current imbalance measuring system such as Ground Fault Circuit Interrupter (GFCI). The optional return conductor and metal foil/mesh hot spot detection shields cancel electromagnetic field. The heater may contain positive temperature coefficient (PTC) continuous sensor to control the temperature in the heater.
