Abstract: A guide for making non-linear patterns using a long arm quilting machine is used to form a variety of different non-linear stitching patterns in a quilt or other workpiece. The mechanism includes a crossmember which locks adjustably between the fixed tracks of a conventional quilting machine bed or table, and an arm adjustably secured to the crossmember. The arm is slotted to provide both radial and linear adjustment relative to the crossmember. The guide attachment end of the arm provides for the selective attachment of any of a series of different templates thereto. The templates include guide slots or passages therein, with a guide pin or stylus engaging the template slots or passages. The stylus is in turn affixed to the sewing machine, causing the machine to form a stitching pattern according to the specific pattern of the selected template as the stylus travels in the selected slot or passage.

Abstract: A high power, high frequency radio transmitter is connected to an antenna through an adjustable impedance coupling device which comprises a helical coil having a number of straight-sided triangular turns. Remotely operable, pneumatic cylinders are mounted on each side or segment of the coil turns in electrical contact therewith and have piston rods which can be moved into and out of electrical contact with a respective fixed conductive member or bus disposed alongside the coil. Additionally, a number of capacitors can be connected into the coupler circuit as required by the similar movement of piston rods into contact with a similar bus, each such piston rod being housed within a pneumatic cylinder electrically connected to a respective one of such capacitors.
