Abstract: A feed trough for an electric arc furnace includes first and second arcuate plates, each arcuate plate having opposing first and second end edges and opposing first and second side edges. The first and second end edges include an arcuate contour, and the first and second end edges of the first and second arcuate plates are attached and first and second side edges of the first and second arcuate plates are attached. A channel is disposed between the first and second end edges, first and second side edges, and inner surfaces of the first and second arcuate plates, The channel includes at least one serpentine flow path and at least one perimeter flow path, the at least one serpentine flow path is disposed toward a midline of the feed trough and the at least one perimeter flow path is disposed outwardly of the at least one serpentine flow path.

Abstract: A system (100) includes a first assembly (110A) and a second assembly (110B). The first assembly (110A) includes a body (120) forming a first interior volume, a plunger (130) comprising a first distal end disposed within the first interior volume, a wire comprising a first distal end secured to the first distal end of the plunger (130), and a plunger clip (140) configured to interface with the plunger (130) and the body (120) to prevent actuation of the plunger (130). The second assembly (110B) includes a cowl (150) forming a second interior volume, a needle comprising a hub and a shaft, and a cowl cap disposed partially within the hub to secure the implant in the shaft. A first distal end of the shaft is connected to the hub. The hub is disposed within the second interior volume. The shaft is configured to receive an implant.

Abstract: The present invention is directed to a method of preparing a sustained release biodegradable ocular insert or implant comprising melt extruding or injection molding a polymer composition and an active agent to form an insert or implant suitable for administration to the body. e.g., ocular administration. The method comprises feeding the polymer composition and the active into an extruder; mixing the components in the extruder; extruding a strand; and cutting the strand into unit dose inserts or implants.

Abstract: A vibratory apparatus includes a deck assembly with a longitudinal axis, an inlet end, and an outlet end. The deck assembly includes a plurality of deck sections each having a plurality of openings. Each deck section has upstream and downstream edges, the downstream edge of each successive deck section disposed closer longitudinally to the outlet end than the downstream edge of each preceding deck section. The upstream edge of each successive deck section is disposed closer longitudinally to the upstream edge of each preceding deck section than the downstream edge of the preceding deck section is disposed to the upstream edge of the preceding deck section, thereby defining an overlapping portion of the preceding deck section and a non-overlapping portion of the preceding deck section. The overlapping portion has larger openings than the non-overlapping portion for each preceding deck section.

Abstract: A vibratory apparatus including a trough having one or more decks, with an inlet end and an outlet end, a first plurality of isolation springs disposed between the trough and ground, and a two-mass, sub-resonant frequency exciter supported on the trough. The trough and the exciter move 180-degrees out of phase with each other. The apparatus also includes a dynamic balancer including a plurality of isolation springs disposed between the exciter and ground.

Abstract: A vibratory apparatus includes a first sidewall, a second sidewall and at least one pair of mated interior walls, the first sidewall, the second sidewall and the at least one pair of mated interior walls depending longitudinally between an inlet end and an outlet end. The at least one pair of mated interior walls is disposed laterally between the first and second sidewalls. At least one deck depends between the first and second sidewalls, and is divided into longitudinally depending sections by the at least one pair of mated interior walls. The apparatus also includes an exciter coupled to the at least one deck.

Abstract: A bidirectional vibratory feeder for transporting objects in a curved path has a trough assembly including an elongated, generally horizontal bed defining the curved path, and a center of gravity. Resilient isolators are connected to the trough assembly and adapted to isolate the trough assembly from underlying terrain. An exciter mass assembly includes an exciter frame and a vibration generator coupled to the exciter frame for generating vibratory forces, the exciter mass assembly having a center of gravity. At least one horizontally disposed resilient coupling is connected between the exciter mass assembly and the trough assembly, and at least one vertically disposed link is connected between the exciter mass assembly and the trough assembly.
