until the offset e develops for actuator rod 220 the actuator rod 220 is in a passive phase while section 246 is in the passive phase section 216 is pushing actuator rods 210 and 220 this will move actuator rod 220 far enough into section 246 for section 246 to operate in the next phase in this respect the linear actuator 228 may be likened to a combustion engine with multiple cylinders fig3 is a stator 250 for a paraffin rotary engine the stator 250 has cooling ribs 252 to accelerate the cooling rate of the paraffin not shown in the appropriate phase the stator 250 has a slot 254 to accommodate a rotor disk 260 as shown in fig3 the actuator rods 262 are located along and shaped to fit the circumference of the circular rotor disk 264 the power of the paraffin rotary engine is transmitted via an output shaft 266 mounted in the center of the rotor disk 264 the rotor disk 264 has marks 268 applied to its surface in circumferential repetition a sensorcontroller 269 is mounted on the stator 250 the sensor controller 269 sense the position of the marks 268 with respect to the stator 250 to control the heating and cooling of the sequence according to the table below fig3 is schematic section of a chamber 256 located inside of the stator 250 of a paraffin rotary engine not shown actuator rods 262 are inside of sections 270 to 274 of.
