Abstract: TORQUE METER MEANS                     ABSTRACT           A torque meter which measures the torque of a rotating shaft includes at least two sensors.  Portions of each sensor are fixed to the shaft.  The sensors provide shaft pulse signals at the same frequency but having a phase difference corresponding to the torque experienced by the shaft.  A clock provides clock pulses.  A circuit connected to the sensors and to the clock provides first groups of pulses in accordance with the shaft pulse signals so that the number of pulses in each group of the first group of pulses corresponds to the torque experienced by the shaft at a constant speed.  A first counting network counts the pulses from the circuit.  Another circuit connected to the clock provides second groups of pulses and is responsive to the speed of shaft rotation so that a ratio of a  group of pulses from the first group of pulses to a corresponding group of pulses from the second group of pulses averages out errors due to the shaft rotation and the sensors.  A second counting network counts the pulses from the second pulse means.  Both counting networks are reset every revolution of the shaft.  An output circuit provides an output corresponding to the torque experienced by the shaft in accordance with the ratio of the counts in accounding networks.                    I

Abstract: IMPROVED GROUND FAULT CIRCUIT INTERRUPTER      UTILIZING A SINGLE TRANSFORMER                           ABSTRACT A single transformer is alternately operated as a differen-tial current transformer with its secondary winding connected as the input to a low impedance differential amplifier with large negative feedback during a ground fault current sampling period and then as a coupled resonant circuit operating into a negative resistance network during a neutral-to-ground resistance sampling period.  During the fault current sampling period, the amplifier is gated ON and OFF to switch the transformer secondary loading between essentially short-circuit and open-circuit conditions.  The result-ing amplifier feedback current pulses, indicative of transformer secondary current, are integrated either directly or indirectly, to develop a DC signal proportional to any ground fault current.

Abstract: GRATE PREHEATER KILN SYSTEM                 ABSTRACT OF THE DISCLOSURE         Grate burner fuel supplies additional heat to the grate preheater for accomplishing more calcining.  A cooler recoup system directs cooler recoup air to the grate fuel burner as preheat combustion air for the fuel burner.  The cooler recoup air is also directed to the grate preheat zone as preheated combustion air for fuel in the pellet bed.  Cooler recoup air is also directed to the drying zone.  The cooler recoup system is controlled so that excess cooler recoup air is bypassed to the waste gas system to dump excess air.  Also, a cooler recoup fan speed or damper is regulated to control kiln firing hood pressure by varying the flow.  In addition, there is provided the cooler recoup excess air bypass damper for controlling duct pressure to stabilize air flow in the system by varying the flow to the waste gas system.  The dis-closed apparatus operated according to the method herein dis-closed provides improved fuel economy, more effective control and reduction in waste gas, thus reducing heat consumption to provide improved fuel economy with better control of the pre-heating and drying operation.
