Abstract: An X-Y shifting mechanism (25) is disclosed for controlling the shifting of a shift rail (17) in a first (Y-Y) transverse direction. The mechanism includes a shift finger assembly (39) including a shift finger (23). A lever member (57) is pivotable about the axis (A) of rotation. When the lever member (57) is pivoted, the movement is transmitted through a spring (91) to rotate a spring seat member (73), thus causing pivotal movement of the shift finger (23). During a non-synchronous engagement, kick-out movement causes pivotal movement of the shift finger in the opposite direction, compressing the spring (91) rather than damaging the shifting mechanism.  The disclosed mechanism also enables preselection of neutral, compressing the appropriate one of the springs (91), such that the preloaded spring will move the shift finger and shift rail to the neutral position as soon as a torque break occurs.

Abstract: Methods and apparatus for identifying the occurrence of fusing electrical attachment during fusing operations are provided. After a conventional fusing operation is complete, an electrical signal is applied to the fusing electrode while the fusing electrode is returned to its home position. The electrical signal is monitored to determine whether a Circuit path exists from the fusing electrode through the fused conductors to the ground electrode. The presence of a path would indicate that the fusing electrode has become attached to the fused conductors.        An alternate embodiment is also described in which the force required to withdraw the fusing electrode is monitored while the electrode is returned to its home position. If the measured force does not fall within predetermined limits, or if the measured force varies during electrode movement, fusing electrode attachment has occurred.

Abstract: The invention relates to a hot peel carrier for decorative graphics and lettering applied to a substrate wherein the carrier has a film having opposite surfaces and an adhesive having a peel strength which decreases with increasing temperature, the adhesive being on a surface of the plastic film.      The invention also provides a laminate for use in applying graphics to a substrate which incorporates the carrier, methods of using and methods of using the carrier and laminate disclosed herein. The various embodiments disclosed herein incorporating the aforementioned hot peel carrier have significant advantages stemming from the fact that immediate after a graphic is heat applied to a substrate, the adhesive of the carrier has substantially no adhesion to either the substrate or to the heated adhered graphic. As a result, the carrier may be immediately removed from the heat applied graphic and underlying substrate without the use of any external force in the form of pulling or stretching. As a result, the invention may be used to provide high production volume capabilities in heat applied graphic and lettering processes, in addition the invention is particularly applicable to the production of multi-component letters or graphics wherein more than one color is desired.
