Abstract: The outer surface of a metal electrode 202 of a rechargeable oxide-ion battery (ROB) cell is covered by its own dense electrolyte 204 and interconnection 206, where the dense electrolyte 204 and interconnection 206 hermetically seal the metal electrode away from oxygen-containing environment to prevent direct contact between active metal and oxygen which would lead to self discharge, thus, producing a self-sealed metal electrode of a ROB cell without introducing additional sealing components.

Abstract: A method for determining transmit power spectral density (PSD), includes: calculating time sharing parameters corresponding to transmission patterns for all users in each frequency band; and determining transmit PSD according to the transmission patterns and the time sharing parameters. A device for determining a transmit PSD including a calculation module and a PSD determining module is disclosed as well. Using the solution, the time for determining the transmit PSD can be saved.

Abstract: A push in a game of Pai Gow Poker is eliminated by determining whether or not corresponding predetermined entities in a banker's holding and a player's holding have numerical values that are either both odd or both even.

Abstract: Household Safety Lock device includes two different screw thread connecting parts separately connecting to a regular lock and a household ware. They can join together or divide separate easily with a bar. So every dangerous household ware is easily locked for protecting children.Gun Lock Guard device includes regular trigger lock section and permanent lock section. The device will lock or unlock the trigger temporarily whenever using the real key. But it will lock the trigger permanent deadly whenever trying unlock the trigger with counterfeit key or destroying the lock. This device increases safety for guns.

Abstract: A switching mechanism interfaces a flexible shaft to a handle of a circuit interrupter which is rotatable in an arcuate path between an on position and an off position. The switching mechanism includes a handle attachment attached to the handle for rotating the handle between the on position and the off position, and a bracket pivotally mounted to the handle attachment and attached to the flexible shaft for movement thereby. The handle attachment may also extend a length of the handle. The switching mechanism may further include a baseplate for securing the flexible shaft thereto and attached to the circuit interrupter. The bracket may have a generally U-shape, two arms pivotally mounted to the handle attachment, and a base which is attached to the flexible shaft. The handle attachment may be generally U-shaped and have a base and two arms which each are pivotally mounted to one of the two arms of the bracket.

Abstract: The present invention discloses an improvement of a mouth-to-mouth resuscitation device characterized in that it has a lower casing and an upper casing separated by a pliable and elastic diaphragm. The elastic diaphragm is upheld by two struts affixed to the lower casing and urged against the bottom of the upper casing to seal any communication between the upper casing and the lower casing and thus preventing air from leaking into said upper casing from lower casing under normal conditions. When the diaphragm is urged by air pressure from the upper casing the portions of the diaphragm not being upheld by the struts will be bent down to allow air to flow into the lower casing. And when the air pressure from said blow-in portion stops, the diaphragm will return to its normally closed portion and seal the upper chamber from the lower chamber.

Abstract: A retractable handle mechanism for controlling the operating handle of a circuit breaker. The handle mechanism consists of a housing which may be mounted on an electrical enclosure in which the circuit breaker may be disposed. Pivotally attached to the housing is a first lever which is movable between an on position and an off position. Retractably attached to the first lever is a second lever which is movable between a first position substantially adjacent the first lever and a second position substantially extended away from the first lever. The retractable handle mechanism may also be equipped with a lever restraining mechanism which allows the second lever to be non-movably disposed in either its first position or its second position. The retractable handle mechanism may also be equipped with a lever off locking mechanism which prevents the first lever from being moved from the off position to the on position.

Abstract: A molded case circuit breaker includes an interlock which prevents the operating handle from being moved from the on position after the main contacts have been welded together. By preventing the operating handle from being moved from the on position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.
