Abstract: A regulating device for a polyphase electrical circuit, having a motor with windings corresponding to the main supply lines for the circuit. Leads are connected to each of the windings and contain a relatively low m.f.d. capacitor for suppressing spikes and similar transients in the respective supply lines, and a relatively high m.f.d. capacitor for functioning as a phase converter in the event the current in the respective supply line is interrupted. By-pass circuits are provided for each of the low m.f.d. capacitors corresponding to a respective supply line, containing relay means in the circuit responsive to the supply line to by-pass the low m.f.d. capacitor in the event the current is interrupted in the respective supply line, thereby permitting the high m.f.d. capacitor to function as part of a phase converter.

Abstract: A process for drying grain in which the grain is first heated to drive off a portion of the moisture as it passes along a conveyor, and the heated and partially dried grain is then discharged into a holding or steeping bin where the moisture in the center of the kernels migrates to near the surface and the temperature becomes substantially uniform throughout. The grain is then discharged onto a second belt where the grain is first heated to drive off a substantial part of the moisture remaining in the grain and then is cooled before it is discharged from the apparatus. Air is used to cool the grain before it is discharged and this partially heated air is utilized in both grain heating operations.

Abstract: An appartus and process for drying grain in which the grain is first heated to drive off a portion of the moisture as it passes along a conveyor, and the heated and partially dried grain is then discharged into a holding or steeping bin where the moisture in the center of the kernels migrates to near the surface and the temperature becomes substantially uniform throughout. The grain is then discharged onto a second belt where the grain is first heated to drive off a substantial part of the moisture remaining in the grain and then is cooled before it is discharged from the apparatus. Air is used to cool the grain before it is discharged and this partially heated air is utilized in both grain heating operations. The apparatus includes upper and lowersections with porous conveyor belts for moving the grain between a receiving hopper to the bin and from the bin into a discharge recepacle.
