Abstract: Support rails are provided for pinball machine playfields that provide mechanical support as well as light-emitting elements, such as LEDs, that generate additional light for illuminating the playfield and/or decorative features affixed to the rails. At least a portion of the support rail is preferably made of a transparent or translucent material to facilitate transmission of light from lighting elements below or enclosed by the rail. The support rails can be provided with various grooves, channels, and holes to facilitate mounting of the rails to a playfield or an existing support rail, using nuts and bolts, screws, brackets, and the like. The lighted support rails provide both mechanical stability to the playfield, as well as additional illumination and optional mounting locations for decorative features and/or game mechanisms.

Abstract: An extensometer includes a first element and second element to be set at a predetermined distance apart, with a coupling for setting and holding the two elements at the predetermined distance apart. The coupling is movable by the action of a biasing force to an engaging disposition in which it engages with the two elements to set and hold the two elements at the predetermined distance apart, and the coupling moves under action of the biasing force to a disengaged disposition in which it no longer holds the two elements at the predetermined distance apart upon removal or sufficient relaxation of the applied force.
