Patent number: 7871247Abstract: A high modulus component, such as an aircraft engine turbine blade, is formed from a base metal that has a high modulus crystallographic orientation that is aligned with the primary, i.e. radial, direction of the turbine blade. The base metal is Ni, Fe, Ti, Co, Al, Nb, or Mo based alloy. Alignment of a high modulus direction of the base metal with the primary direction provides enhanced high cycle fatigue life.Type: GrantFiled: August 17, 2007Date of Patent: January 18, 2011Assignee: United Technologies CorporationInventors: Dilip M. Shah, Alan D. Cetel, Alan W. Stoner, William P. Allen

Patent number: 5687679Abstract: A thermal barrier coating for high temperature applications has improved resistance to heat flow. The coating comprises a large number of these (nanometer scale) layers separated by interfaces which are effective in retarding heat flow. The coating material will typically be oxide based ceramics and the coating has particular applications in gas turbine engines.Type: GrantFiled: May 28, 1996Date of Patent: November 18, 1997Assignee: United Technologies CorporationInventors: Richard S.

Patent number: 5346563Abstract: Superalloy articles are made more oxidation resistant by a process which includes heat treating the article in the presence of foreign chemical species, at a temperature at which the foreign chemical species reacts with and modifies any oxide film present on the article surface. The heat treatment is best carried out at a temperature above the gamma prime solvus temperature of the article and below the incipient melting temperature of the article. Alternatively, the heat treatment may be carried out within the range defined by the incipient melting temperature of the article and about 150.degree. C. below the incipient melting temperature of the article. At such temperatures the foreign chemical species reacts with and modifies the oxide film on the article surface. Sulfur is then able to diffuse through such modified film, and a more oxidation resistant component is produced.Type: GrantFiled: April 14, 1993Date of Patent: September 13, 1994Assignee: United Technologies CorporationInventors: William P. Allen, Norman S. Bornstein, Stephen Chin, Michael DeCrescente, David N. Duhl, Donald R. Parille, Roscoe A. Pike, John G. Smeggil

Patent number: 5344510Abstract: Superalloy articles are made more oxidation resistant by a process which includes heating the article in an environment having a reduced pressure of inert gas and a low partial pressure of oxygen to a temperature at which the sulfur in the article diffuses out. The heat treatment is best carried out at a temperature within the range defined by the incipient melting temperature of the article and about 150.degree. C. below the incipient melting temperature of the article. Alternatively, the heat treatment may be carried out at a temperature above the gamma prime solvus temperature of the article and below the incipient melting temperature of the article. At such temperatures, sulfur readily diffuses out of the article, and a more oxidation resistant component is produced.Type: GrantFiled: April 14, 1993Date of Patent: September 6, 1994Assignee: United Technologies CorporationInventors: William P. Allen, Donald R. Parille

Patent number: 5035259Abstract: A valve for use e.g. as a pilot valve in an offshore water deluge fire fighting system has a ported cylindrical body and an elastomeric sleeve defining between them an annular passage for flow between the various ports. Selected ports can be closed by means of captive balls which are cammed out by a central spool to deform localized areas of the sleeve into sealing contact with the housing wall surrounding the port openings. In this way the moving parts of the valve are isolated from the fluid by the sleeve and problems of sticking, e.g. caused by salt deposits when used with seawater, are avoided. In another embodiment, a flat pad of elastomeric material is used to the same effect in a ported body defining a planar flow passage.Type: GrantFiled: August 16, 1990Date of Patent: July 30, 1991Assignee: Chubb Fire LimitedInventors: William P. Allen, Peter Miles

Patent number: 4593790Abstract: A multi-purpose convertible ladder stabilizer, particularly adapted to stabilize the upper free end of ladders such as the extension type during utility in the construction, maintenance, repair, painting of commercial and domestic buildings. The stabilizer is characterized by its portability and function convertibility wherein it may be removably set for disposition as an outside corner clutch, an inside corner engager, a building overhang ladder attachment, window spanner and the like. A coactive relationship is provided between elements wherein interconnected articulable extensions and a ladder during use, irrespective of the geometric vertical configuration of that elevated part of a building which may be considered the workplace.Type: GrantFiled: April 17, 1985Date of Patent: June 10, 1986Inventors: James S. Brewer, William P. Allen

Patent number: 4317121Abstract: A flush-mounted HF (2 to 30 megahertz) transmitting and receiving antenna is developed which is especially suitable for installation on a Jeep (CJ7) type vehicle. This antenna is formed by bonding a copper strip to the inside surface of the non-metallic top of the vehicle. The strip is grounded to the vehicle body just aft of the driver's door and runs overhead to the aft right lower corner of the non-metallic vehicle top which becomes the feed point for the antenna. The strip is connected in two places to an isolated aluminum skin bonded to the top of the vehicle. The antenna is suitable for use as a transmitting antenna provided an impedance matching device (coupler) is inserted between the antenna and the transmitter/receiver.Type: GrantFiled: February 15, 1980Date of Patent: February 23, 1982Assignee: Lockheed CorporationInventors: William P. Allen, Jr., Benjamin S. Zieg

Patent number: 4085740Abstract: A method for measuring such physiological parameters as pulse rate and respiration without physically connecting electrodes or other sensors to the body. A beam of phased energy, for example microwaves, is directed toward the body of a person at a region thereon which undergoes physical displacement corresponding to variations in the parameter being measured. The phase relationship of the energy reflected from the body is compared with that of the transmitted energy to determine the extent of physical movement of the body region as affected by the parameter being measured. The present method may be used as an overt or covert lie detection technique.Type: GrantFiled: March 28, 1966Date of Patent: April 25, 1978Assignee: Lockheed CorporationInventor: William P. Allen, Jr.

Patent number: 4078793Abstract: Portable apparatus for delineating a playing area including a plurality of elongate members of appropriate length for defining sides of the area. One pair of the members are channels which have ends cut to the form of blunted arrowheads. Another pair of the members, referred to as side members, have apertures extending therethrough adjacent their ends adapted to receive the arrowhead ends of the channels therethrough with the diverging lugs on the ends of the channels releasably locking the channels to the side members in desired angular relationship. One of the side members has an enlarged coupling head extending therealong and the other side member has a coupling groove extending therealong adapted frictionally to receive and hold a coupling head therein. Adjacent frames formed by the interconnection of the members may be releasably connected to each other by insertion of a coupling head on a side member of one frame into the coupling groove of a side member on another frame.Type: GrantFiled: July 25, 1975Date of Patent: March 14, 1978Inventor: William P. Allen

Patent number: 4017152Abstract: A portable projection screen including a sheet of flexible material and a collapsible support for the sheet. The support includes a central hub member having a plurality of sockets therein. Multiple extensible-contractible rods fit at one set of their ends in the hub member and radiate outwardly therefrom. The outer ends of the rods are received in connectors secured to edge margins of the sheet, and when the rods are extended they tense the sheet into a substantially planar surface. A collapsible mast is provided for supporting the screen above a horizontal surface, or for hanging it on a wall.Type: GrantFiled: May 14, 1975Date of Patent: April 12, 1977Inventor: William P. Allen
