Inventor: MCCORMICK DAVID R
IPC: C23C22/83
Filed: 1998-08-21
Granted: 2008-05-13
Abstract: Defects in an initial protective coating, particularly a conversion coating, on a metal substrate can be touched up so as to at least equal the original coating in corrosion protection by use of a dry-in-place aqueous acidic liquid comprising: fluorometallate anions; a component selected from the group consisting of phosphorus-containing inorganic oxyanions and phosphonate anions; and an oxidizing agent, preferably a mixture of hexavalent and trivalent chromium. Other preferred optional active ingredients include free fluoride ions, which stabilize the fluorometallate ions against the formation of precipitates, and a fluorinated surfactant. The same composition also forms an effective protective coating over previously uncoated metal, particularly aluminum. The compositions do not contain any substantial amount of silica, which has often been previously used in compositions for similar purposes.

Abstract: An integral headwall structure constructed of lightweight reinforced composite and incorporating a rigid polymer concrete core in selected portions, for use with standard culvert or drainage pipes in infrastructure water management systems in substitution for conventional concrete headwalls. The headwall structure has a vertical back wall with an integral pipe stub surrounding a central orifice. The pipe stub is preferably cross-sectionally dimensioned and configured to be identical to a selected standard pipe section end so that such pipe section can be connected to the pipe stub without an adapter. A tray is joined to the lower edge of the back wall. A pair of outwardly flared sidewalls are joined to the back wall and to the tray. Angled brace panels extending from the sidewalls to the tray reinforce the sidewalls. The tray, sidewalls and brace panels define the water channels. Front and side brace panels define a recess into which earth enters and against which earth bears to provide stabilization. The sidewalls and all or selected ones of the brace panels may be curved to form a curved continuum.

Title: Aircraft air-conditioning apparatus with water separators
Inventor: MUELLER WOLFGANG
IPC: B64D13/06
Filed: 2000-08-03
Granted: 2009-02-10
Abstract: A system for air-conditioning the cabin of a passenger aircraft using externally provided fresh air as well as bleed air tapped from the engine of the aircraft includes at least one heat exchanger, a blower, a compressor, an expansion turbine, a condenser, a reheater, a first high pressure water separator, and a second low pressure water separator. The several components are connected to each other by air lines such as air ducts, with control valves interposed therein. Two separate air-flow paths representing two different sub-systems are formed. A first air--flow path uses the high pressure water separator while a second air-flow path uses the low pressure water separator. These two air-flow paths or sub-systems can be operated separately and independently of each other by appropriately switching respective shut-off valves. In this manner, the operation of the air--conditioning system can be adaptively switched to achieve an optimal operation under different operating conditions of the aircraft and different air-conditioning requirements.

Title: Structural reinforcement member and method of utilizing the same to reinforce a product
Inventor: BROWN GORDON L JR
IPC: E04C2/38
Filed: 2000-10-16
Granted: 2003-12-16
Abstract: A reinforcing grid which advantageously includes fibers of both a first type and a second type is provided. The first type of fibers have a strength sufficient to reinforce the hardenable structural material, such as concrete, after hardening. The first type of fibers also have a higher resistance to degradation in the hardenable material than the second type of fibers. As such, the first type of fibers will continue to reinforce the hardened material in the event the fibers of the second type become corroded in the hardened material. Consequently, a less expensive type of fiber can be used as the second type of fiber and can corrode in the hardenable material without concern for the strength of the hardened structural product. According to one embodiment, the first type of fibers comprises carbon fibers and the second type of fibers comprises glass fibers.

Abstract: To test closed containers, e.g. with regard to residual air volume or the quality and tightness of the closures which are attached to containers, mechanical oscillations are excited in the closure, the mechanical oscillations are analyzed, measurement values are derived from this, these measurement values are compared with pre-set values for acceptable closures and a signal is produced which states whether the measurement value corresponds to a value for an acceptable closure.     To increase the reliability of the test, the oscillation properties of the closure blanks (R) are also ascertained before their attachment to the containers (B) and the range of acceptable values of the closures (V) attached to the containers (B) is chosen according to the oscillation properties of the corresponding closure blank (R). The closure blanks (R) can be classified according to their oscillation properties.

Title: Universal media ratings selector
Inventor: SIDDIQUI NAJMUL H
IPC: G06F21/62
Filed: 2001-03-27
Granted: 2006-05-23
Abstract: A method for interacting with a user when establishing preferences for a media player that enables a user to quickly set his or her preferences by interacting with a graphical display. The media ratings system is converted to a numerical or ordered range so that the ratings are placed in a progressive order from least objectionable to most objectionable. One possible implementation is to associate a numerical value with each rating and then order the ratings in accordance with the numerical sequence. Once the ratings are ordered, the ratings are displayed to the user in a graphical fashion so that the user can select a position on the graph that represents the user's preferences without necessarily requiring the user to understand the underlying implications of the media ratings system.

Granted: 2004-09-21
Abstract: The disclosure discloses a method for extending the length of time over which a cordless telephone system can operate without an external source of power. The method involves detecting a power supply outage, determining that a telephone call is not currently being handled, placing the portable unit into a mode of reduced power consumption, and placing the base unit into s mode of reduced power consumption. After a period of time, the base unit resumes functionality, determines whether a call is being initiated, and handles any such calls. If the system is not active, the base unit re-enters its mode of reduced power consumption, and tile cycle is repeated.
