A connector set adapted for releasably connecting a gas conduit from a gas appliance or the like to a gas line to provide gas to the appliance. The connector set comprises a nipple adapted to be connected to the gas conduit and a receptacle adapted to be connected to the gas line. The receptacle has a socket adapted to receive the nipple, and first and second valves. The valves are each operable between an open position and a closed position and arranged so that gas can pass from the gas line to the socket only when both valves are in their open positions. The receptacle further includes a mechanism for operating the second valve as the first valve is operated so that the second valve opens when the first valve opens and closes when the first valve closes. The first valve is operable only when the nipple is in the socket, and the nipple is removable from the socket only when the first valve is in its closed position.

A high speed device (10) for safely removing residual yarn (18) from a paper tube (16) without damage to the latter is provided which includes a specialized multiple-blade cutting assembly (20) serving to completely strip yarn from the tube (16) without tangling. The overall device (10) includes a mandrel assembly (14) for supporting a tube (16) to be processed, together with a shiftable carriage (94) supporting the cutting assembly (20) for axial movement of the latter along the length of the tube (16). The cutting assembly (20) has a high speed, metallic leading cutting blade (68) together with a relatively low speed, synthetic resin trailing cutting blade (70) presenting a serrated outer periphery. The leading blade (68) is oriented slightly above the outer surface of the tube (16) for cutting the majority of the residual yarn (18), whereas the trailing blade (70) is positioned for contacting the tube (16) and removing any yarn remnants (18a). A third anti-tangling blade (74) of relatively small diameter is also provided adjacent the blades (68, 70) for removing any yarn picked up by the cutting blade (70).
