  • Patent number: 6897418
    Abstract: A temperature sensor for use in hot runner systems includes a resistive element which is connectable via contacting means to a control circuit for a heating device and which includes at least one element portion of larger electrical resistance than its remaining portions, preferably larger by a factor of 2 to 100. The resistive element portions may form U-shaped bows or loops or may be meandering. Two resistive tracks above one another are separated by insulating layers, e.g. ceramic dielectric layers. The resistive element portions may consist of different materials. In connection with a heating device, the temperature sensor is located on or in the body of a manifold or a nozzle, with meandering and/or bifilar heating conductors whose electrical resistance in the middle is smaller than in the top and bottom regions. The temperature sensor portion is tightly enclosed in a zone of high resistance by adjacent heating conductors.

  • Patent number: 6888102
    Abstract: A carpet seaming iron has two heating elements to maintain the iron at desired temperature with a minimum of temperature oscillation. One element remains energized as long as the iron is switched on, while the other is controlled by a thermostat. With proper selection of the power of the first heating element, the iron achieves a very steady, minimally-oscillating temperature by cycling the second element on and off in response to actual iron temperature during use, supplementing the first element as needed. Larger oscillations such as exhibited with single-element thermostat-controlled irons are avoided by the relatively smaller power of the second element, the only element cycled on and off, even when the thermostat is mechanical.

  • Patent number: 6875955
    Abstract: A thermal activation device has a thermal head having heat generating elements for thermally activating a heat-sensitive adhesive layer of a heat-sensitive self-adhesive sheet. The heat-sensitive self-adhesive sheet has a sheet-like substrate having a printable surface on a first side thereof and the heat-sensitive adhesive layer on a second side thereof. An energy control device controls the thermal head by applying one or more voltage pulses to the heat generating elements for energizing the heat generating elements to thereby thermally activate an area of the heat-sensitive self-adhesive layer in one step. When a series of the voltage pulses are applied to the heat generating elements, the energy control device selectively switches between the heat generating elements to be energized by the voltage pulses each time one of the voltage pulses is applied.

  • Patent number: 6866776
    Abstract: A base for warming massage nodes of a hand-held therapeutic device includes a housing, terminals connectable to a power supply, a seat for seating the massage nodes, and a heating circuit positioned to provide heat proximate to the massage nodes when the massage nodes are seated in the seat. The massage nodes can comprise an outer layer of stainless steel or iron and a core of material other than or in addition to air. The core absorbs or retains heat for a preferably gradual release over time. A method for warming such massage nodes includes selectively disposing the massage nodes in the housing adjacent to a heater, energizing the heater, permitting the heater to warm the massage nodes, and separating the massage nodes from the heater. The massage nodes can be separated from the heater by a magnetic extraction using the hand-held therapeutic device.

  • Patent number: 6864467
    Abstract: An electric heater for gaseous media with at least one support plate and at least one helix of corrugated, electric resistance heating wire wound continuously around the support plate and whose turns are held by means of heating wire bend-offs on the longitudinal edges of the support plate is characterized in that the heating wire is positioned in such a way that it only contacts longitudinal narrow sides and/or edges of the longitudinal narrow sides of the support plate, the bending angle being much larger than 40°. This significantly reduces the risk of thermal damage to the heating wire, particularly in the vicinity of the plate edges. As a result of the largely naturally stable design of the heating wire, the heater according to the invention requires no spacers between the support plates and is therefore particularly simple and inexpensive to manufacture.
