| 249 | Battery cell bypass switch | US286579 | 1999-04-05 | US06093896A | 2000-07-25 | Jui-Yu Wu; Matthew B. Dalton |
| A system (10) for establishing bypass of a failed battery cell (18) includes a failed cell sensor (26) which on sensing a failed cell generates an electric signal that destroys clamping relation of two retaining wire spools (24) to release retaining means (14,16).

| 250 | Method and apparatus for interrupting a current carrying path in a multiphase circuit | US994142 | 1997-12-19 | US6028753A | 2000-02-22 | Christopher J. Wieloch; David J. Benard; Gernot Hildebrandt; Paul T. Nolden |
| A multiphase circuit interrupter includes a plurality of power phase sections for establishing and interrupting electrical power carrying paths for a plurality of phases. Each power phase section includes first and second conductive regions which contact one another to complete the current carrying path for the phase. The second conductive region is movable to an interrupted position to interrupt the path. An interphase current carrying path is established between the power phase sections to conduct electrical energy between the sections following a trip event in any one of the sections. The interphase current carrying path may be established by a conductive element extending between the power phase sections. Channels may be formed in the interrupter housing between the power phase sections to communicate conductive plasma generated during separation of the contact regions from one another between the power phase sections. The electrical energy conducted between the sections increases the rate at which the arcs are extinguished, contributes to protection of the load downstream of the device and results in more rapid interruption of power through all power phase sections. | ||||||
| 251 | Thermally-activated switch for short-circuiting a battery cell | US687955 | 1996-07-29 | US5898356A | 1999-04-27 | Peter Ffrecheville Gascoyne; Geoffrey John Dudley |

| 252 | Automotive battery connector assembly | US626869 | 1996-04-03 | US5716243A | 1998-02-10 | Fritz Josef Alois Kourimsky |
| An automotive battery connection assembly comprises terminals for automated connection to battery posts, and a housing with plus and minus pole circuitry mounted therein. The terminal comprises a contact section and a rotatable spring element that has tabs that cam against the periphery of the contact section. Rotation of the spring element thus clamps the battery post between the spring element and the contact section. The latter design enables robotic assembly of the battery terminals to battery posts, for example by means of a tool having pins that engage in slots of the spring element. Within the housing, a linear actuation motor drives a bridge element between tabs of the plus and minus pole circuits respectively for short circuiting the battery in the occurrence of an accident. The short circuiting blows the high current fuse thereby disconnecting power supply to most devices of the automobile. The latter is to prevent occurrence of electrical fires. | ||||||
| 253 | Cell bypass switch | US187016 | 1994-01-27 | US5438173A | 1995-08-01 | Edward Rudoy; Leslie Kerek |
| The present invention is a cell bypass switch particularly designed for aerospace applications. The cell bypass switch can sense a battery cell failure and automatically opens an alternate path around the failed cell, bypassing the failure and allowing the remainder of the battery system to continue its function. The cell bypass switch is designed to be placed in parallel with the battery cell it protects. The present invention includes two electro-mechanical actuator assemblies which are mounted on the top end of the housing for operating two plungers respectively. Each of the electro-mechanical actuator assembly includes two spool halves which are held together by a tight winding of a restraining wire that terminates in a bridge wire connecting two electrical terminals of the electro-mechanical actuator. Each spool, by virtue of the restraining wire winding, can restrain a spring loaded plunger. However, when sufficient electrical current is passed through the terminals and the bridge wire, the bridge wire will heat up and break under the applied tension load. This causes the restraining wire to unwind, separating the spool halves and releasing the plunger. | ||||||

| A capacitor bank comprising a plurality of capacitor units coupled in parallel, and an energy absorbing resistor Rj is inserted in series with each one Cj of the capacitor units. Thus, when a capacitor unit Cj suffers an insulation failure, the energy flowing into the failing capacitor unit Cj from the other capacitor units is absorbed substantially by the resistor Rj. The capacitor bank may comprise several serially connected rows of parallel connected capacitor units, an energy absorbing capacitor Rij being inserted in series with each one Cij of the capacitor units. Further, each capacitor unit Cj may be provided with a protective short-circuiting device Sj, which short circuits the two terminals of the capacitor unit Cj via a bypass line 9 upon an occurance of failure of the capacitor unit Cj. An oscillation preventing resistor Ry is connected in series with each capacitor unit Cj in addition to an energy absorbing resistor Rx. | ||||||
| 255 | Arc shorting device | US146297 | 1980-05-05 | US4347414A | 1982-08-31 | Peter Headley; Thomas Kelsey; John Murdy |
| In or for a fluid-filled metal-clad switchgear an automatically-operating device for short-circuiting an internal arc in the earthed metal enclosure comprises a piston movable in a cylinder mounted on the enclosure wall, with a rod projecting towards the interior space filled with insulating medium. A pipe or other means connects the space to the cylinder at the remote side of the piston, so that on occurrence of an internal arc in the enclosure the rapid pressure rise creates a pressure differential across the piston to drive it and the rod inwardly and cause the rod to engage the high-voltage conductor and short-circuit the arc to the earthed enclosure. The piston is held normally by a spring or by breakable pegs. | ||||||

| A current sensing, self-heating device for protecting equipment against abnormal current levels which is automatically resettable under mild overcurrent conditions and nonresettable under severe overcurrent conditions. The device comprises a thermostat metal assembly with a temperature compensating portion and an actuating portion which is placed adjacent a nonresettable two-position snap-acting blade electrically connected to ground. During normal operation current flows from the line source through the actuating portion of the thermostat metal assembly to the equipment. However, if an overcurrent condition occurs the heat generated in the actuating portion of the assembly will bend the assembly and cause it to make contact with the blade shorting the current from the line source to ground. As long as the overcurrent is not above a prescribed level, the assembly will bend back out of contact with the electrically grounded blade and again provide current to the equipment upon resumption of normal current levels. But if the overcurrent is above a preselected level, thermostat assembly will cause the nonresettable blade to snap to permanently electrically ground the device. | ||||||
