A glass coated gas dispersing impeller. The impeller comprises a hub, having a centrally located hole. The hole has a central axis and is sized for passage over a drive shaft having an essentially vertically extending longitudinal axis so that the central axis of the centrally located hole corresponds with the longitudinal axis of the shaft. The impeller has a plurality of angles and edges, all of which have a rounded configuration. The impeller further comprising a plurality of blades secured to the hub that extend radially outward from the central axis. Each of the blades has a leading concave surface and a trailing convex surface both of which are defined by a lower edge, an upper edge, an inner edge and an outer edge. The concave surface is configured so that the upper edge overhangs the lower edge. The blades may be connected to the hub directly or by intermediate connecting means such as a disk or arm integral with the hub and extending radially outwardly from the central axis. The hub and its attached blades are covered by a contiguous coating of glass. The impeller has superior ability to disperse gas at high gas velocities without flooding when compared with known glass coated turbines.

High gas dispersion efficiency glass coated impeller

A glass coated high axial flow impeller, including a hub and attached blades. The hub has a centrally located hole, where the hole has a central axis. The impeller has a plurality of angles and edges, all of which have a rounded configuration to permit glassing. The impeller further includes at least two variable pitch blades. Each blade has front and rear surfaces both defined by an inside edge having a leading end and a trailing end, an outside edge having a leading end and a trailing end, a leading edge connecting the leading end of the inside edge to the leading end of the outside edge and a trailing edge that connects the trailing end of the inside edge to the trailing end of the outside edge. The outside edge of each blade is from about 1.5 to 2.5 times the length of the inside edge. The blades are symmetrically attached to the hub at their inside edges; so that, their inside edges are at an angle of from about 45 to about 60 degrees from the central axis of the attached hub and their outside edges are at an angle of from about 50 to about 70 degrees from the central axis of said hub. The angle of the inside edges to the central axis of said hub is from about 6 to about 12 degrees less than the angle of the outside edges to the central axis. The hub and its attached blades are covered by a contiguous coating of glass.

High axial flow glass coated impeller

A flexural spring support for a vibratory apparatus comprises a unitary metal body which includes a substantially stationary member, an oppositely disposed spaced member intended to move in a plane, and a plurality of flexural spring beams coupling the members to one another. Each flexural spring beam is constructed as a substantially constant strain tapered beam.
