Abstract: An apparatus and method for simultaneously cutting parallel slots in a pavement surface is provided, especially for dowel bar retrofit load transfer restoration at joints. The apparatus includes a movable frame lockable with a brake, plurality of parallel cutting blades rotatably mounted on twin cutting heads on the frame, vertical travel unit for raising and lowering the blades independently or in unison, and horizontal travel units for moving the blades horizontally. One of the twin cutting heads is mounted on each side of the frame, with hydraulic adjusting rams for independently setting the width therebetween. A slurry control system which is mounted on the frame provides the blades with coolant and vacuums up the slurry produced during cutting.

Abstract: In a false twist or friction twist texturing machine of the type wherein a plurality of rotatably mounted spindles each carry a plurality of friction discs which overlap and through which a thread is passed along a zig-zag path between the spindles and over the edges of the friction discs, the friction disc assemblies are improved to the extent that they are formed of a circular base member extending outwardly from an arbor which is then mounted on one of the spindles. Such base members include an inwardly extending peripheral groove and a separate, ring-shaped friction member formed of a resilient material having a relatively high coefficent of friction and formed of such size and shape as to be releasably snap-fit into the groove, whereby when worn out the ring is replaced and the base member reused.

Abstract: A blade guard is mounted to a conventional carton cutter for longitudinal, reciprocal movement between a "safe" position outwardly of and covering the tip of the cutter blade and a retracted position spaced inwardly from and exposing the tip and a portion of the blade. The guard is normally spring biased to the safe position, yet responsive to pressure against the carton wall to retract the guard until it passes the end of the carton wall in front of the blade.
