Abstract: An electronic device, while displaying a representation of a piece of music, detects a first input event at a location corresponding to the representation of the piece of music, and in response, provides tactile feedback that corresponds to at least a subset of beats of the piece of music. Subsequently, in response to detecting a second input event at the location corresponding to the representation of the piece of music, the electronic device ceases to provide the tactile feedback that corresponds to the beats of the piece of music.

Abstract: An improved relief valve is disclosed for use with a pressurized system. The improved relief valve includes an integral drain line coupling that prevents the outlet of the relief valve from being plugged or restricted in any manner such that discharge from the pressurized system flows uninhibited to an appropriate drainage point. The coupling includes a nipple which is rigidly secured to the outlet of the relief valve and which is coupled by a nut member to a drain line. In addition, the nipple is adapted for receiving a wrench for countervailing a torque transferred to the nut member.
