US Patent:

39704807, Jul 20, 1976

Filed:

Feb 19, 1975

Appl. No.:

5/550981

Inventors:

Jacob E. Schmidt - Little Falls NJ

Assignee:

McGraw-Edison Company - Elgin IL

International Classification:

H01M 1036

US Classification:

136177

Abstract:

An air-vented battery cell containing liquid electrolyte is rendered leakproof against spillage during shipping and during usages when the cell is tilted from a vertical position in any direction to a horizontal position, as when used on a marine buoy, by providing the cell with a vent reservoir across the top thereof having a liquid connection with the cell at only one corner thereof and having a vent tube in the reservoir at the top part thereof, leading through one end wall diagonally to nearly an opposite corner portion thereof. In three tilt positions of this cell at 90. degree. intervals from a vertical to a horizontal position, a limited flow of electrolyte into the reservoir is well below the inner open end of the vent tube, and in the fourth such tilt position the electrolyte in the reservoir enters the vent tube through only a small length, typically 10-20% thereof, with the result that the cell is protected against any leakage from shaking thereof while tilted and is provided further with a reserve against leakage through the vent tube if an increase in gas pressure occurs within the cell while it is so tilted.

Abstract:

A vacuum tube assembly for removing material is disclosed, including: a vacuum generator configured to generate a vacuum airflow; one or more tubes coupled to the vacuum generator and configured to channel the vacuum airflow; and an actuation mechanism coupled to the one or more tubes, wherein the actuation mechanism is configured to actuate at least one tube from a first position relative to a material stream to a second position relative to the material stream, wherein the first position is farther from the material stream than the second position.

International Classification:

E01B 31/26
B05B 13/06
B05C 1/16

Abstract:

Systems and methods for automated repair and maintenance operations on a railroad track comprise a work head that is automatically moved over the railroad track according to a predetermined pattern, such as the movement of an applicator for tie plugging compound according to a predetermined pattern of spike holes. The automated repair and maintenance operations may be coupled to systems and methods for automatically detecting a feature on a railroad track that comprise two or more distance measurement sensors that travel over the railroad track. Features on the railroad track are detected where the distance measured by each sensor falls within two different predetermined distance ranges.
