Food warming or cooling package thermometer assembly
The present invention is a thermometer assembly adapted to be utilized to sense the temperature of a material within a container, such as a food item heating or cooling container. The assembly includes a spout connected to the container, a closure releasably engageable with the spout, and a temperature sensing element engaged with the closure. The closure and spout allow a food item to be inserted into and withdrawn from the container after preparation, while the temperature sensing element, when engaged with the closure, senses the temperature of the food item within the container and emits both visible and audible signals regarding the temperature of the food item.

Photonic bandgap reflector-suppressor
A computer-based design methodology for photonic bandgap devices that permits determination of both the upper and lower bandgap edges in either a one-dimensional or two-dimensional photonic crystal. Using this methodology, a one-dimensional crystal may be created for use in a waveguide-fed microwave oven as a radiation reflector-suppressor, particularly for undesirable higher harmonic frequencies of about 12 GHz. By conceptually arranging multiple reflectors in a desired geometry, a two-dimensional crystal may be created that is particularly useful as a waveguide or splitter. The waveguide or splitter thus created has especially high efficiency for microwave wavelength ranges of about 9 GHz as compared with the prior art and is particularly useful in communications applications.

Hot wire igniter
A hot wire igniter for igniting a gaseous or atomized fuel is disclosed. The coil of the hot wire igniter is formed from a thin high temperature, iron, chromium, aluminum alloy having a center section that is tightly wound. The coil turns initially do not touch one another and each end of the coil is attached to a rod that is received within an insulator member. The rods are connected to a power source. The coil portion of the hot wire igniter is received within a gas collector box which is attached to the burner to be ignited. Application of the power source to the lead-in rods causes the coil of wire to reach a temperature in excess of the ignition temperature of the fuel mixture which surrounds same causing the ignition of the mixture.

Redundant control circuit for hot melt adhesive assembly heater circuits and temperature sensors
A redundant control circuit comprises a pair of heater circuits for heating a hot melt adhesive hose assembly to a predetermined temperature level, and a pair of temperature sensors which are used to sense the temperature of the hot melt adhesive hose assembly and to control energization of the heater circuits in order to maintain the desired temperature level. A first one of the heater circuits would initially be electrically connected to the hot melt adhesive hose assembly electrical circuitry, and in a similar manner, a first one of the temperature sensors would likewise be electrically connected to the hot melt adhesive hose assembly electrical circuitry. Subsequently, should a failure occur within the first one of the heater circuits, then an electrical switch mechanism would be activated so as to effectively remove the first, failed heater circuit from the hot melt adhesive hose assembly electrical circuitry, and substantially simultaneously, electrically connect the second one of the heater circuits to the hot melt adhesive hose assembly electrical circuitry. Similar switching procedures would also be implemented in connection with the pair of temperature sensors should a failure occur within a first one of the temperature sensors initially incorporated within the hot melt adhesive hose assembly electrical circuitry.

Tube and method for bracing functional elements in the same
Functional elements, particularly PTC heating elements, are braced in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one anther and flat sides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. This makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.

Tacking method and apparatus
An apparatus for tacking a multi-lumen tubular assembly together comprises a laser, an optical member and a placement tray for retaining the tubular assembly. A portion of the optical member defines a window that is substantially transparent to laser energy emitted from the laser. The window has a substantially concave shaped surface. The placement tray and the window surface define a processing area for positioning at least a portion of the tubular assembly. The processing area receives the laser energy that is emitted from the laser and passed through the window of the optical member. The tubular assembly is defined by an outer tubular member disposed about at least a portion of at least one inner tubular member. The laser energy transmitted into the processing area is transmitted substantially through the outer tubular member and is substantially absorbed by at least one region of the least one inner tubular member.

Heating resistances and heaters
A heating resistance 1 comprises a shaped body of a band made of a conductive material obtained by bending the band in a shape of a wave. The heating resistance 1 is fixed to a substrate made of an insulating material to obtain a heater. Alternatively, the heating resistance comprises a wound body of a band made of a conductive material. According to the present invention, the heating value per a unit length can be easily designed and changed, and the reliability can be improved and abnormal heat generation can be prevented at the interface where the heating value per a unit length is changed.

Carbon heating element and method of producing same
A carbon heating element having an arbitrary specific resistance and an arbitrary shape which are arbitrary necessary as a heating element, and a method of producing the same. The carbon heating element is obtained by uniformly dispersing one or at least two metal or metalloid compounds into a composition having shapability and showing a high yield of a carbon residue after firing, shaping the dispersed material-containing mixture thus obtained, and firing the shaped material under a nonoxidizing atmosphere.
