Patent number: 7216433Abstract: The present invention relates to a reciprocating saw tool (10) having a motor drive (17) with a reciprocating driver (21) for a tool (15) and having a mass equilibrating body (22). In addition, a device (20) is provided, which serves to convert a rotary movement of the motor drive (17) into a reciprocating movement of the reciprocating driver (21) along a first movement axis (41) and an opposite reciprocating movement of the mass equilibrating body (22) along a second movement axis (42). For improving the sawing performance, the mass equilibrating body (22) is guided at an angle ? to the reciprocating driver (21) so that its movement axis (42) is constantly at an angle to the movement axis (41) of the reciprocating driver (21).Type: GrantFiled: May 5, 2005Date of Patent: May 15, 2007Assignee: Hilti AktiengesellschaftInventors: Guenter Haas, Louis Widmer

Patent number: 7134374Abstract: A safety cable cutter used for cutting a cable used in servicing an oil and gas well. A centrifugal arm roller and a guide roller are mounted on top of a frame. The cable is received on the rollers as the cable is lowered down a well bore. Mounted on ends of the centrifugal arm roller is a centrifugal arm attached to an arm coil spring. The coil spring holds the centrifugal arm next to the end of the roller. Opposite ends of a clamp attached to a cutter bar are slidably received in a pair of cutter bar guides. When the centrifugal arm roller exceeds a certain speed indicating a free fall of the cable, the bias force of the arm coil springs is overcome and the arms move outwardly. Contact ends of the arms engage the opposite ends of the clamp. The clamp and cutter bar are then moved outwardly and the cutter bar cuts the cable.Type: GrantFiled: October 21, 2004Date of Patent: November 14, 2006Inventors: Alan M. Williamson, Cody Williamson

Patent number: 7096770Abstract: There is provided an optical recording medium-manufacturing apparatus that is capable of accurately transferring a disk-shaped apparatus during a manufacturing process, and at the same time occupies a small installation area. A control section causes a cut-forming machine installed at a cut-forming location to form a cut in a resin layer of a disk-shaped substrate, then causes an indexing mechanism to rotate a transfer stage to thereby transfer the disk-shaped substrate formed with the cut to a central hole-forming location, and then causes a punching machine to punch a central hole.Type: GrantFiled: January 23, 2004Date of Patent: August 29, 2006Assignee: TDK CorporationInventors: Junichi Ide, Haruhiko Yamaguchi, Takeshi Umega, Futoshi Kobayashi, Tsuyoshi Itoh, Yoshimi Yodogawa, Mamoru Usami

Patent number: 7047859Abstract: An optical recording medium-manufacturing apparatus which is capable of reducing wear of a cut-forming blade section used for forming a cut in a resin layer, without increasing the component costs of the apparatus. An ultrasonic horn includes a hollow-cylindrical cut-forming blade section for being pushed into a resin layer formed on one side of a disk-shaped substrate, thereby forming a circular cut in the resin layer. A control section controls motion of the ultrasonic horn caused by a moving mechanism. The control section causes the ultrasonic horn to be pushed in to the resin layer while causing ultrasonic vibration thereof to thereby form the cut, and while maintaining a state of ultrasonic vibration of the abutment section and a pushed-in state of the cut-forming blade section, causes the punching blade section to be pushed into the disk-shaped substrate, to form the central hole.Type: GrantFiled: February 26, 2004Date of Patent: May 23, 2006Assignee: TDK CorporationInventors: Junichi Ide, Takeshi Umega, Haruhiko Yamaguchi, Futoshi Kobayashi, Tsuyoshi Itoh, Yoshimi Yodogawa, Mamoru Usami

Patent number: 7044040Abstract: Leading and trailing edge stitch tab scrap strippers utilize pivot arms which are secured to die block bodies for pivotable motion intermediate their two ends. One end of each arm is adapted to engage a stitch tab scrap portion to be stripped and to effect the removal of the tab scrap from a box blank from which it has been cut. A biasing force is applied against a second end of the pivot arm. The pivot arm is caused to pivot in response to the rotation of an upper male slotting head and a lower die cutting anvil. This pivotal movement is effective to strip or to eject the severed stitch tab scrap.Type: GrantFiled: March 29, 2004Date of Patent: May 16, 2006Assignee: Sebring Container CorporationInventor: Richard W. Smith
