Abstract: A bracket assembly for mounting a plurality of photovoltaic (PV) accessories, the bracket assembly comprises a first bracket and a second bracket. The first bracket comprises a first clamp member and a second clamp member attached by means of a tightening means. The first clamp member includes a first plate and a second plate with an opening being attached to form an angle therebetween. The second clamp member includes a clamp plate with a slot and a pair of flanges. The second bracket comprises an attachment structure having a pair of outer channels with a structural member connected therebetween and a middle channel attached and positioned at a lower plane with the structural member, a pair of arms and a plurality of flanges attached to a distal end of the pair of outer channels, the middle channel and the pair of arms.

Abstract: A mechanism for cracking nuts utilizing a rotating member including a plurality of cells. Each cell of the rotating member is sized to contain a single nut which is accessible through an entrance to the cell. The cell also includes a plate against which the walnut may rest. Each nut, if elongated, is oriented in each of the cells such that the long axis of the nut lies between the entrance and the plate of each cell. Cracking heads are employed in association with each of the cells such that any single cracking head is sized to move freely in and out of the entrance of each of the cells and may contact the nut within each cell. A striker or impact producing device imparts an impinging force to any of the cracking heads to crack the nut between the cracking head and plate within each of the cells of the rotating member.
