Abstract: A bracket assembly for attaching a shelf to a support structure at different angles. The bracket assembly comprises a bracket, an adjustment structure, and a locking structure. The bracket comprises a shelf support surface and a projecting portion with a notch extending from an attachment side of the bracket. The adjustment structure comprises a number of sides that are moveable between a plurality of different positions to change the shape of the notch in the projecting portion for attaching the bracket to the support structure at different angles. Different sides of the adjustment structure may be positioned to change the size of the notch for attaching the bracket to support structures with different thicknesses of material. The locking structure is configured to prevent movement of the adjustment structure when the adjustment structure is in position.

Abstract: A pusher tray assembly comprises a hanging tray and a sliding tray having a wire track, the sliding tray moveably connected to the hanging tray by fins of a pusher, the pusher slidingly engaged to the wire track for movement between a first position and a second position.

Abstract: A roller track comprising a base, a tray, and a plurality of rollers. The tray is configured to slide into the base, and comprises a first end, a center portion comprising a plurality of notches, and a second end. The first end is removably engaged to a first end of center portion. The second end is removably engaged to a second end of center portion. The first end and the second end comprise a plurality of slots. The plurality of rollers is configured to engage the plurality of notches.

Abstract: An apparatus and method to retain a product support, displaying the product in a container, in adjustment panels mounted to a frame. Each adjustment panel may mount to the frame at a particular inclination angle, and include a number of serpentine slots for engaging a number of support pins extending from sides of the product support. Each serpentine slot in the number of serpentine slots may include a notch at each end, and at each direction change, of the serpentine slot. Each notch in a particular serpentine slot may be a different distance from a top edge of its respective adjustment panel. A first product support may be retained in a notch such that a top edge of a first container with a first depth on a first product support is substantially level with a top edge of a second container of a second depth on a second product support.

Abstract: A pusher shelf assembly may comprise a wire grid assembly affixed to a left bracket and to a right bracket. The wire grid assembly may have a plurality of wires and one or more pushers slidingly engaged to at least two wires in the wire grid assembly. The left bracket and the right bracket may be configured for removable engagement to a wall of a product display. The product display may be a freezer.

Abstract: A compact, extended life, gas laser comprises a capillary tube with a transition portion having a reduced wall thickness. The laser includes a cathode which is cylindrical in a rearward cathode region and hemispherical in a forward cathode region. The configuration of the capillary tube and the cathode cooperate to inhibit short circuiting of the bore to cathode discharge path and thereby extend the life of the laser.
