Abstract: Each glass gob is severed by a shear blade pair (6; 9). The shear blades (7, 8; 10, 11) are arranged on shear arms (12, 13) whose movement is synchronized with each other by means of a gear mechanism (16) A first shear arm (12) is drivable pivotably by a drive means (36), while a second shear arm (13) is supported by an air spring (28). The drive means (36) is carried on a carriage (39) which is displaceable by piston-cylinder units (48, 49). The drive means (36) drives a crank pin (43) which is connected by means of a coupling rod (44) with the first shear arm (12). By displacement of the carriage (39) one achieves a servicing stroke (34) which is greater than the working stroke (32) of the shears.

Abstract: A recirculation valve for cooling a centrifugal pump. The invention comprises a valve casing having a first chamber for connection to a centrifugal pump and a second chamber for connection to a fluid outlet, a recirculation port for redirecting fluid from the first chamber to the centrifugal pump. Between the first and second chambers is a check valve means for permitting fluid flow from the first to the second chamber. Connected to the check valve means is a hollow cylindrical valve stem permitting flow from the first chamber to the second chamber. The check valve means is comprised of a circular disc which opens when the fluid pressure in the first chamber exceeds the fluid pressure in the second chamber and closes when the fluid pressure in the second chamber approaches that in the first and intermediate chambers. A two angle control surface between the check valve disc and the valve casing controls the position of the check valve relative to the flow of fluid past the valve.

Abstract: A general electro-rheological valve is disclosed used in controlling the flow of fluids in a variety of applications. The valve comprises an inlet in communication with a fluid source, an outlet for transporting the fluid out of said valve, and an oscillating valve member for opening and closing off said inlet. The valve member has a cavity containing an electro-rheological fluid, a perforated electrode member emersed in the electro-rheological fluid within the cavity, and means for electrifying the perforated electrode member such that the electro-rheological fluid within the electrode solidifies, thereby locking the position of the valve member relative to the electrode. In this manner, the valve member, which oscillates with respect to the perforated electrode member, can be frozen in an open, closed, or intermediate position with respect to the inlet. The valve member thereby controls the level of fluid flow through the valve.

Abstract: The present invention provides improved method and apparatus for the transfer and delivery of very high purity chemicals for use in semiconductor production and similar processes. By employing multiple alternating pressure vessels, chemicals are drawn from virtually any bulk source and delivered to one or more end-users.
