Abstract: A heating system for providing heat to a draped basin containing liquid above the drape. In addition to having at least one temperature sensor that controls a flow of electricity to the heating element, the system has at least one air gap detector in thermal contact with the heating element. Each air gap detector responding to a temperature above a high setpoint temperature for that air gap detector by interrupting the flow of electricity until detecting that the temperature has fallen below a reset setpoint temperature for that air gap detector so that an air gap in proximity to the one of the air gap detectors is prevented from causing a severe temperature excursion in a portion of the draped basin. Thus, the drape is protected from a local temperature excursion.

Abstract: A method and apparatus for providing short arc welding-type power is disclosed. The system includes a power supply, a wire feeder, and a controller. The output current is decreased at dive rate when the arc forms. The dive rate is maintained until the currents drops to a threshold, preferably a function of the peak short current in that cycle. Then the current is held steady for a length of time that is a percentage of the short time for that cycle. Then the current is decreased at the normal rate until the short reforms, and the current begins increasing at the normal rate. The holding steady portion can be omitted.

Abstract: A light diffusion plate is placed on an upper surface of an upper chamber window. A blasting process is applied to a lower surface of the light diffusion plate to provide the lower surface in the form of frosted glass. When the light diffusion plate is placed on the upper surface of the upper chamber window, the light diffusion plate and the upper chamber window do not closely adhere to each other. The frosted glass releases a mass of air entering between contact surfaces of the light diffusion plate and the upper chamber window to the outside even if the mass of air thermally expands during heat treatment. This restrains the occurrence of a phenomenon in which a thin layer of air is trapped between the light diffusion plate and the upper chamber window to prevent the sliding of the light diffusion plate resulting from the air layer.

Abstract: A laser processing head for a laser beam uses actuators engaged with a delivery fiber end to deflect the fiber end relative to an optical axis. The laser beam from the fiber end is collimated by a collimator and is then focused by a focusing lens disposed in the head beyond the collimator to a focal point. The focal point of the laser beam is deflected from the optical axis in relation to the deflection of the fiber end. The fiber end and the actuators are housed in a sealed module. Deflection of the laser beam can be sensed by reflecting portion of the laser beam to a sensing element so a control system can monitor and control the fiber end's movement.
