A battery operated standby power system, including a microboard; at least two rechargeable batteries mounted to the microboard; a charger for selectively charging the at least two batteries; at least two, or dual, inverters, one inverter being assigned to each of the at least two batteries; a plurality of outlets, the outlets being configured to selectively deliver 120 VAC, 240 VAC and both 120 and 240 VAC from the batteries through the inverters.

Solar and plug automatic rechargeable 12/24 volt battery power backup unit

A backup power system for a structural appliance normally operated by a primary source of AC current through a primary circuit includes a backup battery; a charging circuit for connecting the primary source to the backup battery and including a battery charger for charging the backup battery; a backup circuit for connecting the backup battery to the appliance and including a converter for converting DC current from the backup battery to AC current for the appliance; and a switch interposed in the primary circuit and the backup circuit for selectively closing the primary circuit and opening the backup circuit during normal operation of the primary source, and for closing the backup circuit upon at least partial failure of the primary source so as to connect the backup battery to the appliance through the converter, whereby the backup battery is charged and isolated from the appliance during normal operation of the primary source, and the backup battery is connected through the converter to the appliance for supplying AC current to the appliance upon failure of the primary source.

Backup device for electric appliance

An outer ring is formed with counterbores at the ends thereof, disposed along a common axis and separated by a radially inwardly extending keel portion. A polymer liner is inserted into each end of the outer ring into abutment with the keel portion, the polymer liners being preformed with spherically concave inner surfaces conforming to a ball part entrapped therebetween. A portion of the outer ring is then deformed by upset forming over a portion of the polymer liners to lock the polymer liners in position. An electrical sensor for indicating failure of the polymer liners is also disclosed.

Spherical bearing and method of assembling a spherical bearing

A plastic part is molded of a plastic with an inner body of crystalline plastic and an outer surface layer of an amorphous plastic. The amorphous surface layer withstands friction loading at least during an initial break-in period. In one embodiment, the amorphous surface is formed by using a higher plastic melt temperature and/or a lower mold temperature than normal. In another embodiment, an intermediate part is molded as a crystalline intermediate part, and a surface layer is heated and quenched to form the amorphous surface layer on the final part. A bearing cage is molded by injecting the plastic melt at a single point intermediate the ends of a single bar of the bearing cage to permit formation of the desired amorphous layer on rails connected to the ends of the bars.
