摘要： A seal apparatus for a casing of a turbomachine. The seal apparatus may include an annular body having first and second annular body portions and an appendage. The second annular body portion may extend axially from the first annular body portion and may have an outer annular surface radially offset from an outer annular surface of the first annular body portion. The appendage may extend axially from the first annular body portion and may have an outer annular surface and an inner annular surface. The inner annular surface of the appendage and the outer annular surface of the second annular body portion may define an annular cavity therebetween, and at least a portion of the appendage may be configured to be displaced radially outward in order to maintain contact with first and second inner cylindrical surfaces of the casing during radial expansion of the casing.

摘要： An annular seal is provided for use in a turbomachine. The annular seal may form a generally rectangular cross-section and may include an outer radial surface forming an outer sealing surface and defining at least one annular groove and a plurality of slots spaced circumferentially about the outer radial surface. Each slot may have an end terminating in the at least one annular groove. The annular seal may also include a first axial sidewall forming a sidewall sealing surface and a recessed portion and a second axial sidewall opposing the first axial sidewall. At least one annular groove and the plurality of slots may be configured to maintain a low pressure environment across at least a portion of the outer radial surface. The second axial sidewall, the recessed portion, and the inner radial surface may be configured to maintain a high pressure environment there across during operation of the turbomachine.

摘要： A programmable calculator employs modular read-write and read-only memories separately expandable to provide additional program and data storage functions within the calculator oriented toward the environment of the user and two sixteen bit LSI NMOS central processing units. One of the central processing units (LPU) is employed to perform language syntaxing, arithmetic, and general supervision of program execution. The second central processing unit (PPU) is employed for managing input/output operations. Communication between the two central processing units is accomplished by an arrangement through which the two central processing units share a common portion of memory. The calculator also includes a keyboard having a full complement of alphanumeric keys for entering programs and data into the calculator and for otherwise allowing the user to control operation of the calculator. The calculator further includes a CRT that can be operated in either an alphanumeric mode or a graphics mode, two magnetic tape transports that permit the user to store information into and to retrieve information from the user portion of the calculator read-write memory, and an 80-column thermal printer utilizing a print head that includes 560 thermal print resistors arranged in a single horizntal row.
