摘要： A variable transformer comprising an annular core with a winding which at the end surface of the core is provided with a circular contact path to be connected with a current brush mounted on a rotor (7). The current brush consists of a contact roller journalled on a shaft pin (11) which from the rotor (7) is directed obliquely downwardly towards the end surface of the core and inwardly towards the axis thereof. The contact roller includes a double-curved contact path (17) for punctiform contact with the contact path (18) of the winding. The reactive pressure provided by said contact urges the contact roller upwardly along the shaft pin (11) which where secured to the rotor (7) is provided with a contact plate (14) that is in heat-conducting communication with the rotor (7). The contact plate (14) includes a plane circular surface (15) against which a correspondingly plane, circular surface (15') of the contact roller about the bore (12) thereof abuts. The contact roller is delimited by a conical surface the generatrix of which extends from the periphery of the circular surface (15') to the outer periphery of the contact path (17) of the roller. The rotor (7) is bowl-shaped and its top surface shape corresponds to the internal surface of the upper part of a housing for encasing the transformer.

摘要： A gun assembly for bonding a fastener to a workpiece is disclosed which uses heat induction to fuse a thermoplastic adhesive coating on the base of the fastener to the workpiece. The gun assembly has a head member of electrically non-conducting material. A hollowed core electrical conductor is embedded in the head member in a spiral configuration adjacent the surface of the forward end of the head member. Seating means are provided on the forward end centrally of the spiral configuration for receiving the fastener to be applied to the workpiece. An air conduit extending through the head member between its forward and rearward ends is in communication with the seating means. A flux concentrator plate is mounted on the forward end of the head member and surrounds the seating means. A body member slidingly supports the head member and is selectively moved between a retract position and a workpiece engaging position by a piston and cylinder drive means.
