Abstract: A motor starter circuit particularly for compressors of refrigerators, comprising a starter device (1), adapted to be connected to a starter winding (3) and to a steady-state winding (2) of an asynchronous motor, the windings (2, 3) being in turn connected to a power supply line (4, 5), a capacitor (6) being connected in parallel to the starter device (1), and further comprising a heat-sensitive element (7), which is adapted to be connected between the starter device (1) and the capacitor (6) and the starter winding (3).

Abstract: A method and apparatus for providing welding type power is disclosed. A welding type power supply includes an input circuit, a controller and an output circuit. The input circuit receives an input power signal and provides an intermediate power signal. The output circuit receives the intermediate power signal and provides a welding type power output. The output circuit has an inverter with at least two inverter switches, and a clamp circuit that limits the voltage across the inverter. The clamp circuit captures and buffers the excess energy, and returns the excess energy to an input of the inverter over a plurality of switching cycles. The controller has control outputs connected to the input circuit and the output circuit, to control them.

Abstract: An enhanced polymeric void board for placement between adjacent horizontal layers of masonry materials to maintain an opening in a lower of the layers, the enhanced void board comprising a relatively thin planar element having a plurality of ribs extending along the length of the planar element.

Abstract: A lightweight and compact plasma cutting system includes a power source having an inverter and a non-adjustable regulator enclosed within the power source. The inverter is configured to generate a power signal suitable for a plasma arc process and the non-adjustable regulator is preconfigured to deliver a fixed gas flow to a plasma torch for the plasma arc process.

Abstract: The installation tool for a mushrooming expandable anchor has a hollow cylindrical sleeve with an inside diameter, the top having slots for engaging the base of the mushrooming component and a means for engaging and turning a threaded component, which compresses the mushrooming component. The means for turning the threaded component can be a socket, which rotates inside of the sleeve and engages a hex head at the base of the threaded component or alternatively the means for turning the threaded component can be a threaded rod for threading into the base of the threaded component until it reaches the end of the threads in the base. Another means of turning the threaded component is a screwdriver engaging a slot in the treaded component. All of the means for turning the treaded component may be by a powered drill with a connective adapter.

Abstract: The present invention is directed to a bobbin for an inductor assembly that is preferably molded of a plastic material incorporating a flange to maintain a uniform and constant gap or separation between a pair of ferrite E-cores. Preferably, the bobbin includes a number of hollow bosses designed to receive self-tapping screws so as to directly mount the bobbin to a mounting plate. Additionally, a pair of tempered brass spring clips is used to secure the cores to the bobbin. To reduce breakage of the bobbin, each clip engages the bobbin perpendicular to the width of the ferrite core.
