Abstract: In a method for quenching, particularly for steel tubes or similar, the tube (T) is quenched by a vortical flow of cooling liquid at least along the outer shell surface, with at least a circulatory motion inside the tube. The vortical flow of cooling liquid has a component of circulatory motion in the circumferential direction around the outer shell surface of the tube and a component of motion in the axial direction with respect to the tube. A device for the application of the method has a container (1) for the tube (T), with at least one source (18, 217) of supply of an external cooling liquid flow, and with an outlet (101) for the discharge of the flow from the container (1). The source (18, 217) of supply of the external cooling liquid flow is such that it generates the flow in a circumferential direction with respect to the tube (T).

Abstract: A molded one piece thermoplastic seal comprises a tab, a socket depending from the tab, a pair of links extending from the tab and a locking member secured to the other end of the links. A tether is secured at opposite ends to the locking member with one of the tether ends weakened. The locking member comprises a pair of resiliently secured tangs attached to a cross-member in which there are a pair of opposing grooves and a transverse hole for receiving the tether. The recesses and hole are inserted within the cavity of the socket with the tether free end inserted so as to lock the tether within the recesses and hole. The tether includes a plurality of projections, one projecting from the tether on each side of the locking member so that when the tether is locked to the locking member in the socket the tether cannot be removed. In a further embodiment, two locking members each having a pair of locking tangs are attached to a strap in tandem.
