摘要： A heater is provided that includes a resistive layer formed by a layered process (e.g., thick film, thin film, thermal spray, and sol-gel) and two electrical lead wires connected to the resistive layer. The resistive layer has sufficient temperature coefficient of resistance characteristics such that the resistive layer is a heater element and a sensor, and the resistive layer is in communication with a two-wire controller through the two electrical lead wires. Preferably, the sensor is a temperature sensor, and the heater includes additional layers formed by layered processes.

摘要： A hot runner nozzle heater system is provided with a layered heater in communication with a two-wire controller, wherein a resistive layer of the layered heater is both a heater element and a temperature sensor. The two-wire controller thus determines temperature of the layered heater using the resistance of the resistive layer and controls heater temperature through a power source.

摘要： A hot runner nozzle heater is provided that includes a sleeve defining a slot extending along a length of the sleeve. A first dielectric layer is disposed over an outer surface of the sleeve, and a resistive element layer is disposed over the first dielectric layer, wherein the resistive element layer defines a resistive circuit pattern that is preferably formed by a laser trimming process. A pair of terminal leads are secured to a portion of the resistive element layer thus defining a termination area, and the termination area is positioned proximate the slot and away from the proximal end and the distal end of the sleeve. A second dielectric layer is disposed over the resistive element layer but not over the termination area, a third dielectric layer is disposed over the termination area, and a protective layer disposed over the second dielectric layer and the third dielectric layer.

摘要： A pump leak monitor for use with a peristaltic pump comprises a pump housing and a pair of electrical contacts disposed along a bottom end of the pump housing. The electrical contacts are located such that the contacts are immersed in fluid when the pump is leaking. The fluid conducts electricity across the contacts and thereby closes an electrical circuit for providing an indication that a leak has been detected. By measuring an electrical parameter in the circuit, the pump leak monitor is capable of measuring the conductivity of the fluid in the pump housing. As a result, the pump leak monitor is capable of differentiating between different types of fluid.

摘要： A device is provided for transporting, in a stepwise manner, tape between a feed reel and takeup reel. An indexer moves across the normal path of the tape displacing it while the tape on the takeup reel side of the indexer is braked. After displacement, the takeup reel takes up the displaced tape while the tape on the feed reel side of the indexer is braked, providing stepwise tape transport in precise intervals determined by the amount of displacement caused by the indexer.
