An expert system is provided for answering questions provided by a potential purchaser of goods or services using a neutral sales consultant in which a question sentence entered by the purchaser is understood using specialized library tables developed to understand both the subject and form of the question sentence. Thereafter an appropriate or relevant answer to the question is automatically given relating to sale of the product or service. The result is that questions are more easily understoo...

In a neutral section (1) for use with an overhead railway conductor line, which neutral section (1) is disposed between the ends of the conductor line when in use and comprises an insulator (10) to isolate the ends of the conductor line from each other, the neutral axis of the neutral section (1) being such that when the neutral section (1) is in use the neutral axis is aligned closely with the neutral axis of the conductors on its either side and the height of the insulator (10) is chosen so th...

A neutral start switch has a base on which stationary contacts are arranged and a rotor on which movable contacts capable of contacting the stationary contacts are disposed. The stationary contacts include reverse lamp contacts connected to a reverse lamp lighting circuit, position stationary contacts connected to a position signal circuit provided in an electronic control device, and starter stationary contacts connected to a starter motor driving circuit. The contacts are arranged so that cont...

The crankset for the driving of bicycles and other vehicles or machines by muscular force includes two coaxial crank spindles (8, 9), mounted in a bottom bracket tube and each provided with a radial arm (20, 22) beside one or more toothed chain rings driving a chain transmission. The chain ring carrier (15) has an axis (25) offset forwards with respect to the spindles and it is coupled to each radial arm by an articulated connecting rod. Sealing gaskets (42, 46, 53) are placed within the bottom ...

System neutral to earth grounding, over the entire length of an electrical cable is achieved by adding one or more strips of semi-conductive material over the helically or otherwise wound concentric neutral conductors and completing the cable jacket with insulating material. The strip engages the soil when buried to provide a continuous ground path for the neutral conductors. In a second form protrusions of semi-conductive material project from a semi-conductive layer and encircle certain ports ...

Prior neutral forming circuits for use in developing a neutral voltage for loads coupled to an inverter have been unduly large and heavy or have required that the inverter be operated by a half bridge control which causes less easily filtered harmonics to be produced in the inverter output. In order to overcome these problems, a neutral forming circuit includes first and second impedances coupled together at a junction to form a series combination which is coupled across a pair of DC link conduc...

A neutral stop device is provided which prevents the accidental lowering of a truck bed when the spool of the hydraulic valve system is positioned in a neutral location and any force acts on a pull-out cable running from the spool to the truck bed. A stop device is provided having two annular rings, each of which surround a different end of the spool, said rings being connected by a spacer means. Each of the annular rings is adapted to interact with a snap ring provided on the end of the spool t...

A neutral wood containing paper can be produced by adding, to a stock slurry containing mineral filler and a large majority of high yield pulp, a cationized starch, and thereafter bentonite and colloidal silica either simultaneously or successively with a time interval of at most 60 seconds, resulting in an improved retention of fiber and filler, an improved drainage, and a decreased pitch problem.

An essentially neutral pH vehicle wheel cleaner for coated alloy vehicle wheels includes a builder, a surfactant, a buffer, a clarifier or mild abrasive, and a fragrance in water. The builder and surfactant interact to produce strong buffering to prevent a significant change in pH due to alkaline brake dust, road soil, and acidic road salts. A preferred embodiment utilizes tetrapotassium pyrophosphate as the builder, a sodium salt of sulfonated oleic acid as the buffer, and a ethylene oxide addu...

A neutral start interlock for a hydrostatic drive system that uses potentiometers to electronically monitor at least the position of the hydrostatic displacement control such that the engine will not start unless such control is in the neutral position.
