Abstract: The swelling rate of a swelling packer element or a conforming foam screen material is accelerated with heat. In one variation reactants that create an exothermic reaction plus a catalyst, if needed, are allowed to come into contact upon placement at the desired location. The heat accelerates the swelling process and cuts the time to when the next operation can commence downhole.

Abstract: A starter motor includes a motor portion having a stationary field, an armature rotatable relative to the stationary field, an armature shaft coupled to the armature, and a pinion gear slideably disposed relative to the armature shaft and rotatably fixed relative to the armature. The starter motor also includes a solenoid mounted to the motor portion. The solenoid includes a plunger mechanically linked with the pinion gear. The solenoid is configured and disposed to cause the pinion gear to engage with a flywheel as the armature shaft reaches a speed between about 150 RPM and about 250 RPM.
