摘要： A nozzle attachment and method for its use is provided. The nozzle attachment can be affixed to a fluid outlet. The nozzle attachment is constructed and arranged to increase the total output flow, flux, of the fluid outlet by using the high velocity directional fluid flow from the outlet to create a pressure differential between the flow and the surrounding medium, thereby causing fluid particles from the surrounding medium to be drawn into the fluid flow. The nozzle attachment comprises a nozzle attachment fixation element, a funnel element, and a frame connector extending between the nozzle attachment fixation element and the funnel element. The nozzle attachment has many applications and uses.

摘要： Apparatus and method for forming a peripheral skirt on a workpiece of metal or other ductile material with reduced pleating of its peripheral edge. The concentric mating male and female dies of the prior art are provided, and in addition at least one drawbar concentric with, outside of, and generally beside the male die guides the outer periphery of the workpiece as the dies are urged together, preventing the outer margin of the workpiece from being folded under and propagating pleats. The drawbars also assist in clamping the outer margin of the workpiece between the dies when the central portion of the workpiece is to be expanded by the application of fluid forming pressure.

摘要： An adjustable agitator assembly having a hexagonal shaft to which is attached a hexagonal hub. A mounting block is attached to the hub at the desired locations. The mounting block has a receptacle to receive the splined shaft of a paddle. The splines allow the orientation of the paddle to be changed to many different discrete positions while at the same time preventing the paddle shaft from slipping. Seals are used to prevent penetration of the contacts between the various parts of the assembly by the media which is stirred.
