摘要： Submersible electric motors for pumping fluid from wells are assembled together in tandem relationship for increasing total output horsepower. Means are provided to make electrical connections just prior to assembly and interconnect the oil flow corridors between motors during assembly. Precompressed spring-loaded thrust bearings compensate for shaft length changes and dampen vibrations. The oil circulation corridors include filtration.

摘要： In a kitchen, a ventilating hood is disposed over a cooking unit and has an exhaust duct and a return duct, both extending through the roof to the exterior. An exhaust blower is connected to the exhaust duct and an intake blower to the intake duct, outside the building. A by-pass duct extends from the exhaust blower outlet to the intake blower inlet and a damper in the duct is responsive to temperature sensed in the intake duct to by-pass a portion of the air handled by the exhaust blower into the intake blower for return through the hood to the area above the cooking unit. Filtering means are provided in the hood.
