Patent number: 7950379Abstract: An apparatus for moving a mass, the apparatus having an arcuate track, a clamping member attached to a section of the arcuate track, an arm assembly pivotably connected to the clamping member, and a counterweight connected to the arm assembly. A projectile for use in a mass accelerator having an arcuate track, the projectile having a core and at least one of a low-friction layer, a propellant layer, and a polycarbonate layer.Type: GrantFiled: July 16, 2008Date of Patent: May 31, 2011Assignee: Advanced Launch CorporationInventor: Derek A.

Patent number: 7032584Abstract: A spiral mass launcher for moving a mass including a spindle support assembly; connected to a swing-arm pair module. The spindle support assembly rotates on a motor shaft, allowing the swing-arm pair module to swing on a parallel bearing shaft. A spiral track passes through a radial opening in the bearing shaft. Thus, the swinging motion of the swing-arm pair modules allows the spiral track to move in a gyrating motion. The spiral track has a first end and a second end, the first end adapted to receive a mass or projectile and a second end adapted to launch the mass. A mass can be fed into the spiral mass launcher by either a feed mechanism that feeds the mass into the first end of the spiral. Such feed mechanisms include a feed mechanism that linearly oscillates and picks up the mass at a first amplitude of oscillation and feeds the mass into the first end of the spiral track at a second amplitude of oscillation; or a feed mechanism that includes a continuous tube and “crank arm” feed.Type: GrantFiled: May 5, 2004Date of Patent: April 25, 2006Assignee: Advanced Launch CorporationInventors: Derek A. Tidman, Mark L. Kregel

Patent number: 6712055Abstract: A spiral mass launcher is disclosed. The spiral mass launcher includes provisions that permit greater packing density and permit better support of a track. Some of these provisions include the use of specially designed angled swing arms. The spiral mass launcher also includes provisions to assist the spiral in achieving faster gyration speeds. Some of these provisions include improved arm designs and vacuum enclosures. A feed mechanism for a spiral mass launcher is also disclosed.Type: GrantFiled: March 6, 2002Date of Patent: March 30, 2004Assignee: Advanced Launch CorporationInventor: Derek A. Tidman

Patent number: 6014964Abstract: The velocity of a mass is monotonically increased from an initial non-zero value at the time it enters a spiral track. A drive gyrates the track about an axis so the mass makes each turn around the track in about the same period of time. The drive includes plural rotary drive shafts eccentrically and fixedly connected to the track at several points. The drive shafts and track are arranged so points on a first side of a particular spiral turn where the mass is located are driven toward the axis and points on a second side of the particular spiral turn remote from where the mass is located are driven away from the axis.Type: GrantFiled: October 29, 1998Date of Patent: January 18, 2000Assignee: Advanced Launch CorporationInventor: Derek A.

Patent number: 5950608Abstract: A mass located in a track defined by a closed, continuous path is gradually and smoothly accelerated or decelerated by controlling movement of the track so a portion of the track where the mass is sensed to be located is moved inwardly (for acceleration) or outwardly (for deceleration) along a local radius of curvature of the track.Type: GrantFiled: December 22, 1997Date of Patent: September 14, 1999Assignee: Advanced Launch CorporationInventor: Derek A.
