摘要:
The present development is a kit and a method for easily determining the presence of lead on a surface. The kit provides a rhodizonate salt and an aqueous acid mixed together in a container that can deliver a liquid product as a fine particle spray. In a preferred embodiment, the rhodizonate salt is sodium rhodizonate and the aqueous acid is aqueous acetic acid. The method includes mixing sodium rhodizonate and aqueous acetic acid and then delivering it to a surface as a fine particle spray, and monitoring any change of color on the treated surface.

Systems and methods for controlling a throttle plate to adjust airflow to the engine are provided. A transmission having an input speed and an output speed and including a clutch and a driver-selectable transmission lever is controlled to adjust engine speed to a synchronous speed in a future gear ratio in response to driver foot pedal positions and driver-selectable transmission lever positions.

An automatic archiving system that makes document archiving largely transparent to the user. In one embodiment, documents scanned in or printed during the course of office equipment operation are automatically archived. For example, an office local area network (LAN) may interconnect a copier, a printer, a fax machine, and a document management workstation. Whenever, a document is copied, printed, or faxed, a document image is archived by the document management workstation without further user intervention. A single user command results in the document being copied and archived, printed and archived, Of faxed and archived.
摘要:
A method for operating an engine and transmission in a vehicle is described. The method comprises up-shifting the transmission based on whether engine knock limits spark advance at engine conditions after the up-shift. Further, the method may include accounting for differences in fuel types, and their effects on engine knock in future gears.

According to the present invention, an automatic archiving system that makes document archiving largely transparent to the user. In one embodiment, documents scanned in or printed during the course of office equipment operation are automatically archived. For example, an office local area network (LAN) may interconnect a copier, a printer, a facsimile machine, and a document management workstation. Whenever, a document is copied, printed, or faxed, a document image is archived by the document management workstation without further user intervention. A single user command results in the document being copied and archived, printed and archived, or faxed and archived.
摘要:
A system and method for operating an engine having ionization signal sensing include detecting plug fouling and controlling the engine using progressively more aggressive control strategies if the fouling condition persists. A first control strategy may be used when the number of engine starts or running time are below corresponding thresholds and a second strategy otherwise. The first strategy may employ progressively more aggressive control procedures to eliminate spark plug deposits that may include repetitive sparking, exhaust cycle sparking, increasing engine loading, advancing spark timing, increasing air/fuel ratio, and increasing idle speed, for example. The second strategy may include similar corrective actions employed in a different order and/or to a lesser degree in an attempt to eliminate plug fouling without any noticeable change in engine operation or performance as perceived by the vehicle operator. The control strategies may be applied to individual cylinders, cylinder banks, or all cylinders.

A method for controlling an engine coupled to a transmission is described. The method is suited for a transmission having at least one gear in which an over-running clutch is present. The invention describes a method for adjusting an engine operating parameter to maintain transmission input speed at or below a synchronous transmission input speed when the transmission is in the gear with the over-running clutch. The synchronous transmission input speed is based on transmission state and transmission output speed. Alternatively, vehicle speed can be used in place of transmission output speed.
摘要:
A cylinder head assembly for an internal combustion engine including a cylinder head at least partially defining a flow path through the engine, including an intake port, an exhaust port, and a combustion chamber disposed between the intake post and the exhaust port. A valve is coupled to the cylinder head and movable relative to the cylinder head to selectively open the combustion chamber to one of the intake port and the exhaust port. A valve spring is positioned between the valve and the cylinder head and biases the valve to a closed position. A thermally insulating washer is positioned between the cylinder head and the valve spring.

The invention is an amusement device that combines an answer-generating liquid-filled die agitator with a head-shaped outer casing. The head-shaped outer casing resembles an animal or human character, or a fantasy or cartoon character. Preferably the outer casing is made of opaque hard plastic, vinyl, rubber or other rigid material that can be molded to take on the desired shape. The face of the head-shaped casing has a mouth formed in an open position. Inside the mouth is the liquid-filled die agitator positioned so that when the device is tilted backwards the agitator can be viewed to reveal the answer. When the answer is viewed in context with the overall look of the embodiment of the device it has a certain entertainment value.
