Abstract: A slide and glide drum mount system has a first coupling that is configured for removable, fixed attachment to a support post. The first coupling has a stub extending outwardly from a surface of the first coupling. A second coupling that is configured for removable, fixed attachment to a drum. The second coupling having a hole through a surface of the second coupling. The first coupling and the second coupling are removably and slidably connected with the stub disposed in the hole and with the surface of the first coupling and the surface of the second coupling engaged in contact, thereby mounting the drum to support post.

Abstract: A snare drum throw off has handle that is rotatable between a positive engaged position and a positive disengaged position for engaging and disengaging a snare of a snare drum. The tension on the snare when in the positive engaged position is adjustable by a tensioner.

Abstract: A bass drum spur system has a pivot assembly and a spur leg assembly. The pivot assembly has a spur hub removably attachable to a rim of a drum and a hub cover attached to the spur hub. The hub cover has a passageway and a circumferential slot formed through a sidewall of the passageway. The circumferential slot has first and second notches at respective opposite ends of the slot. A release button is axially slidable within the passageway of the hub cover and a spring is disposed in the passageway and biases the release button in a direction away from the spur hub. The spur leg assembly has a post fixedly attached to the release button for movement therewith, wherein the post is movable between engagement with the first notch and the second notch by pressing the release button in a direction toward the spur hub and rotating the post along the circumferential slot.

Abstract: Fish oil is purified by extraction with supercritical carbon dioxide.

Abstract: Polyunsaturated fatty acid moieties in fish oil are concentrated by transesterifying fish oil glycerides with a lower alkanol to form a mixture of lower alkyl fatty acid esters, and extracting the esters with carbon dioxide under supercritical conditions.
