摘要:
A pigment paste suitable for use in cationic electrodeposition is disclosed. The pigment paste comprises a cationic resinous grinding vehicle derived from an epoxy resin containing both quaternary ammonium and ternary sulfonium salt groups. Also disclosed are cationic electrodeposition paints containing the pigment paste and the use of these paints in the process of cationic electrodeposition. The paste improves the stability of lead-containing cationic electrodeposition paints.

A system for scheduling aircraft maintenance includes communications electronics configured to receive data from systems onboard one or more aircraft while the aircraft are in flight. The system further includes computing electronics configured to receive the data from the communications electronics and to update a maintenance schedule for the one or more aircraft based on the received data.

The present invention provides for resource property aggregation. A set of new instances is received from one or more providers. For each new instance in the set of new instances, a determination is made as to whether the new instance represents a same resource as at least one other instance. Responsive to determining that the new instance represents the same resource as another instance, a set of properties associated with the new instance and with the at least one other instance are identified. Each property from the new instance is compared to an associated property in the at least one other instance using a set of precedence rules. At least one property value is identified from either the new instance or the at least one other instance. An aggregate instance is then generated that represents the resource using the identified property values.
摘要:
A heat exchanger including a tube having inlet ends and outlet ends and defining a flow path therebetween. The tube can have a first section and a second section arranged at an angle with respect to the first section. Each of the first section and the second section can include a first subsection and a second subsection arranged at an angle with respect to the first subsection.

A battery charging method (300) determines a current at which to start charging the battery which provides the capability for faster higher current sourcing capability. A start current(Istart)is determined based on the battery's cut off voltage, steady state voltage, and characteristic impedance (314). This start current is then compared and adjusted based on the rated power supply current for the power supply (316, 318) and rated charge current for the battery (320, 322). The adjusted current is then applied to the battery (324) at the beginning of the charge sequence to provide faster higher current sourcing capability.
摘要:
A system for monitoring guiding and controlling an unmanned, unteathered flight vehicle, generally assumed to be moving through the earth's atmosphere at a high rate of speed. The system is comprised of on-board positional receiver and processing means coupled to a transceiver capable of combining such positional information with additional data relative to the health and status of the flight vehicle and transmitting the same to a ground station of compatible and simplified design. A preferred positional determination means is to utilize a form for GPS signal thereby affording one the opportunity to include appropriate processing software or additional componentry if necessary for base station purposes and thereby provide a relatively inexpensive system having a low probability of detection for intercept that simultaneously yields vastly improved operating performance characteristics over the mere translation of received GPS signals to down-link or to remote stations as known in the prior art.
