Filed:

Aug 15, 2000

Appl. No.:

09/639363

Inventors:

Andrew Michael Cross - Willoughby OH

Assignee:

PCC Airfoils, Inc. - Beachwood OH

International Classification:

B22C 904

US Classification:

164516, 1641221, 164 35

Abstract:

An article, such as an airfoil, is cast by a lost wax investment casting process. The process includes providing a core having a configuration corresponding to the configuration of a space to be formed in the airfoil. The core is at least partially enclosed with a layer of wax. A portion of the layer of wax is removed from the core. The step of removing a portion of the layer of wax from the core includes heating a tubular member and melting a portion of the wax layer by engaging the wax layer with the heated tubular member. Molten wax is conducted away from the core through the heated tubular member. A mold is formed by at least partially coating the wax layer with mold material which extends across the core at the locations where the melted wax was conducted away from the core. The wax layer is removed to form a mold cavity which is filled with molten metal to cast the airfoil.

Appl. No.:

12/839823

Inventors:

Douglas M. Bullock - Medina OH, US
Andrew Cross - Chagrin Falls OH, US

International Classification:

B24B 27/00

US Classification:

451177

Abstract:

A rotary finishing device is provided comprising a substantially solid hub having an inner periphery and an outer periphery, the inner periphery defining an axial throughhole. The device further provides a plurality of slots formed about the outer periphery of a generally circular hub, each of the plurality of slots being defined by a pair of side portions extending from the outer periphery. Each of the pair of side portions includes a tip portion, an intermediate side surface portion, and a base portion. The slot increases in width from the outer periphery to the base portion. A finishing media is secured in each of the plurality of slots by an epoxy resin, wherein each of the slots is consumed in its entirety by a combination of mounting ends of the finishing media and the epoxy resin. The hub and the consumed slots form a solid integral finishing device extending from the inner periphery to the outer periphery.

International Classification:

B65H 1610
B65H 2000
B65H 2030
B65H 23185

US Classification:

242 672

Abstract:

Fabric handling apparatus is provided to continuously unwind a fabric sheet being supplied from a supply roll at variable travel speeds for subsequent processing operations. The fabric sheet being unwound is accumulated in storage means enabling the fabric travel speed to be automatically and continuously decreased as fabric is being accumulated while also being automatically and continuously increased as the fabric sheet is being withdrawn from storage.

Appl. No.:

6/587493

Inventors:

Andrew L. Cross - Burton OH
Thomas F. Moran - Aurora OH

Assignee:

Midwest Plastic Fabricators - Chagrin Falls OH

International Classification:

B29D 2300

US Classification:

264573

Abstract:

A method is presented for forming couplings from blanks made from lengths of extruded plastic pipe, to join pipe together. The blank is cut from the length of extruded pipe and heated to the thermoplastic point. The heated blank is mounted between two mandrels which have a slight taper toward the ends, which are beveled. The ends of the mandrels are brought together inside the blank at a uniform rate and force. The pressure between the ends of the mandrels causes a bulge in the blank. A split die clamps around the blank at about the bulge, causing the bulge to collapse and forming a ridge in the inside surface of the blank. Coolant circulates in the mandrels and cools the inside surface of the blank. The mandrels are then withdrawn, leaving the formed blank in the split die.
