Abstract: A gas turbine component that includes a very thin wall. The gas turbine component being of a single-piece, single-cast structure. In one form of the gas turbine component it is formed of a superalloy composition and is capable of withstanding gases impinging upon the walls at temperatures greater than 4000.degree. F.

Abstract: Disclosed is a method of making moldless/coreless single crystal castings of NiAl(.beta.') alloys. Drops of molten NiAl(.beta.') alloy is deposited on a starter seed block of single crystal alloy and casting structures are epitaxially grown to predetermined configurations and shapes by repeatedly dropping and solidifying molten NiAl(.beta.') materials.

Abstract: Disclosed is a single-cast, thin wall structure capable of withstanding impinging gases at temperatures of 4300.degree. F. and higher, and method of making the same. Using a bleed line of the instant invention allows for a decreasing metal pressure with respect to time which prevents any damage to the thin outer mold wall.

Abstract: A ball joint construction having a ball-stud member with a ball portion and a shank portion and an open-ended socket member in which the ball portion is contained. An elastomeric covering is permanently bonded to the ball stud and then deformed for inserting in the socket thereby resiliently interconnecting the socket and ball members. The socket member is provided with an inner wall portion with an outwardly tapered portion toward the bottom end of the socket.

Abstract: A microprocessor with a two bus structure and modulo addressing hardware which converts any section of main memory into an apparent circular address space for use as a five-fold data register. The modulo addressing hardware has a capability for circularly loading data into a sequential order or accessing data repeatedly for the evaluation of recursive algorithms. Thus, the modulo addressing hardware is useful in the rapid processing of such recursive software algorithms and in the solution of various mathematical series. More generally, it is useful for the rapid access of any data in memory. The described microprocessor uses the modulo addressing hardware concurrently with the execution of data manipulation instructions. A 64 bit wide instruction allows control of both modulo addressing hardware and the microprocessor CPU in a single micro instruction.
