Systems and methods of the present disclosure relate to shifting downhole tools based on pressure. A downhole tool comprises an inner sleeve, an outer sleeve including: a chamber and a pressure relief valve in communication with the chamber. A return spring is disposed in the chamber. The outer sleeve is movable in forward and backward directions relative to the inner sleeve. A ball is disposed between the outer sleeve and the inner sleeve. A spacer is adjacent to the ball and a groove is adjacent to the spacer. A pocket is configured to receive the spacer upon movement of the outer sleeve in a forward direction. The spacer is configured to travel to the ball from the pocket and from the ball to the pocket. The pressure relief valve is configured to pass fluid based on a threshold pressure to unlock and move the outer sleeve in a backward direction.

Methods and systems are provided for fabricating a composite structure. In one example, the composite structure may include a honeycomb core sandwiched between face sheets. An edge of the honeycomb core may be abraded and a top face sheet may be perforated. As such, a likelihood of delamination of the composite structure during a curing step may be reduced.

The present invention, a percussion instrument aid is useful to aid in the creation of acoustic vibrations, or more generally, music. The subject instrument includes a striking pad and a striking tip, positioned distally on a lever arm. Further, the lever arm is pivotally attached at a pivot joint to a brace, the brace having a percussion device attached distally from where the lever arm is pivotally attached. The instrument aid is used by displacing the striking pad with a force conveyed by a hand. As the striking pad is displaced, the pivotally attached lever arm is also displaced thereby causing a complementary displacement of the striking tip. The displacement of the striking tip eventually impacts upon the percussive device causing the characteristic vibrations of the percussive device.

A compact disc box container assembly for holding a number of compact disc container boxes and for displaying, illuminating, and viewing the facial informational indicia of the disc boxes. The holder comprises a pair of opposing longitudinal sides defining a structure with angularly disposed channels, at least two tray members, and at least a pair of end caps slidably engaged to the longitudinal sides. The composition of the composing material includes a fluorescent dyestuff for the illumination of the disc boxes, especially from the edges of the elements that make-up the assembly.
