    Abstract: A layout instrument for constructing the two-dimensional sheet pattern which defines a cylindrical article having longitudinal elements of varying lengths, each of which are parallel to the axis of the cylinder, wherein an oblique plane passes through the cylinder and intersects the base plane thereof at an acute angle. The instrument comprises a calibrated miter scale having a series of equally spaced subdivisions which establish the length of the longest and shortest elements of the cylindrical article and a calibrated layout scale having a series of spaced points each of which establishes the length of one of a plurality of specific, circumferentially spaced elements of the cylindrical article.

    Abstract: A self-limiting shaped memory alloy device, including a shape memory alloy member, with first and second ends, a first anchor member connected to the first end, an energy contact, a second anchor member connected to the energy contact, an energy source connected in energetic communication to the energy contact, a moveable member connected to the second end, and a biasing member operationally connected to the moveable member for urging the moveable member towards and into physical contact with the second anchor member. The moveable member is in physical contact with the second anchor member and the second end is in energetic communication with the energy contact. Actuation of the energy source energizes the energy contact. Energization of the shape memory alloy member initiates a phase change that urges the moveable member away from the second anchor member. Movement of the moveable member away from the second anchor member disengages the second end from the energy contact.
