Abstract: An escalator or moving walkway with a handrail and a handrail entryway has a finger contact protection cover, wherein the finger contact protection cover includes corrugated bristles. The corrugated bristles allow the gap between the handrail and the entryway to be minimized. The bristle construction also provides improved tactile feedback when a user's hand contacts the bristles, allowing the hand to be more quickly removed from the handrail and contact with the bristles, avoiding potential injury.

Abstract: A height adjustment mechanism for varying the positioning of a rotating tool on a haft of a machine tool, such as a portable power tool, is in the form of a coupler between the blade and tool arbor. A head of the coupler accepts the tool and connects with a tool drive, the depth of the connection defining the working height or position of the tool. A pair of inter-engaged flanges are mounted upon the shaft of the coupler head, and apply forces to the coupler head and tool drive to maintain the connection depth therebetween and to retain the tool in position. A jam nut further maintains the relative orientation of the flanges.

Abstract: A low-speed projectile is designed for forming relatively large apertures in walls against which the projectile is fired. The projectile includes a penetrator core having a cavity containing an explosive charge activated by a time delay fuse circuit. The time delay is chosen to cause explosive ignition when the cavity and explosive is within the wall to be pierced. The construction of the projectile directs the explosive impulse radially, creating a hole in the wall considerably larger than the outside diameter of the penetrator's core. A preferred application is a projectile for a shoulder-fired weapon.
