Abstract: An iron-type golf club (320) having an iron-type club head (322) with an interchangeable shaft (40) is disclosed herein. The golf club (320) includes a tube (344) mounted in the hosel (331) of the club head (322), and a sleeve (346) mounted on a tip end (50) of the shaft (40). The tube (344) includes a tapered portion (360) and a rotation prevention portion (362). The sleeve (346) has a frustoconical portion (372) and a keyed portion (374) that are respectively received in the tapered portion (360) and the rotation prevention portion (362) of the tube (344). The golf club (320) further includes a mechanical fastener (48) for removably securing the shaft (40) to the club head (322).

Abstract: A milling head for use in conjunction with a rotary milling tool that is utilized to perform an operation on a tube, preferably of a tube bank or tube wall of a boiler system. The milling head is utilized to remove material or film from the outer diameter of a tube, or place a bevel on a tube end, or both. In one embodiment, the milling head includes at least one outer diameter milling element and at least one bevel milling element that are adjustable in relation to each other as well as the milling head body. Methods for milling a tube are also described.

Abstract: A method of processing data traffic at a firewall has been developed. The method prevents unauthorized access to a computer system by first receiving a SYN request for access to a destination in the system at a firewall. Upon receipt of a SYN request, the firewall sends a reply with an SYN/ACK message with changed packet information within the SYN/ACK message. The firewall receives an ACK message in reply to the SYN/ACK message. After the ACK message is authenticated by the firewall, the SYN request is recreated and forwarded to the destination in the system.

Abstract: Tube ends such as those of boiler tube banks, are prepared utilizing any of various combinations of processes which include a step of micro-diameter tube film removal from a portion of a tube end, including an area below a beveled segment, or segment to be beveled. The micro-diameter film removal step provides the tube with an exposed, clean metal surface which is conducive to a subsequent welding or bonding operation performed on the tube. Preferably, the process is performed with a tube milling tool having interchangeable milling or cutting heads. A specialized milling head is also disclosed and, in one embodiment, is at least used to perform the micro-diameter tube film removal step. Advantageously, the tube film removal milling head also removes a weld overlay on one or both sides of a tube in one embodiment. The tube film removal milling head includes an attached blade having a planar face configuration which enables tube film removal.

Abstract: A method of remotely managing a firewall has been developed. The method includes receiving a control data packet at the firewall from a remote location. Next, the control data packet is analyzed to determine if the control data packet is authorized to access the firewall. Finally, an authorized control data packet is allowed to control the firewall.

Abstract: An intelligent firewall that prevents unauthorized access to a system has been developed. The fire wall does not use a communication address. It receives a data packet and analyzes it to determine its final disposition. Finally, the firewall handles the data packet according to its final disposition.
