Abstract: The invention relates to an electric machine (fixed, mobile or portable) suitable to the physical, dynamic, continuous conditioning of materials having the ability to absorb electromagnetic radiation, which have the need to be treated through the irradiation of UV or IR, even without entering into contact with the machine and this also through the vacuum. The invention mainly uses the Lambert and Stefan-Boltzmann postulates, or rather the physical assumptions of the transmission of energy by radiation and in particular the concentration and the emission proximity of energy between transmitter and receiver (which varies with the square of the distance) and the emission intensity (which varies with the fourth power of the temperature). The extremely small distances between transmitter and receiver of electromagnetic energy and the cylindrical shape and concentric electromagnetic emission source (reflected from the outside towards the centre) are the main essence and novelty of the invention.

When the user is reaching for the inner pot handle the fingers will contact the cooker handle, thereby avoiding mistakenly gripping the cooker handle.

Abstract: Welding is performed by alternately switching a pulse arc welding period (where welding is performed by forward feeding a welding wire by a rotation for the forward feeding of a push side feeding motor and a rotation for the forward feeding of the pull side feeding motor and feeding a peak current and a base current) and a short-circuiting transition arc welding period (welding is performed by forward/backward feeding the welding wire by the rotation for the forward feeding of the push side feeding motor and a rotation for the forward/backward feeding of the pull side feeding motor and feeding a short-circuiting current and an arc current). During the short-circuiting transition arc welding period, a forward feeding peak value Wsp and/or a backward feeding peak value Wrp of a pull feeding speed Fw are compensation-controlled based on a wire storage amount of an intermediate wire storage.

Abstract: An apparatus and method are provided for manufacturing an orthopedic prosthesis by resistance welding a porous metal layer of the orthopedic prosthesis onto an underlying metal substrate of the orthopedic prosthesis. The resistance welding process involves directing an electrical current through the porous layer and the substrate, which dissipates as heat to cause softening and/or melting of the materials, especially along the interface between the porous layer and the substrate. The softened and/or melted materials undergo metallurgical bonding at points of contact between the porous layer and the substrate to fixedly secure the porous layer onto the substrate.
