IPC: A01D90/08
Filed: 1980-01-09
Abstract: In an agricultural vehicle, an apparatus for automatically loading bales (5) of material forms successive rows of aligned bales (6, 7, 8) and lifts each row as a unit to form a stack of such rows to a height of N<2> bales.

Title: Dual mode AC motor drive system
IPC: H02P27/06
Filed: 1980-04-10
Abstract: Disclosed is an AC motor drive system having a variable frequency, variable magnitude AC current supplied from a controlled inverter coupled to a variable DC current source in the form of a converter by way of a DC link including an inductor.

The first mode comprises a constant slip or constant angle mode for operating speeds up to the corner point speed which is defined as the speed at which the motor voltage at full torque matches the maximum voltage the variable frequency inverter coupled thereto can provide. Thereafter, the system enters the second mode by automatically shifting to a constant horsepower variable slip or changing angle mode for operating speeds beyond the corner point speed.

Patent ES-8105870-A1 (ES)
Title: Power factor control system for inverter-driven a-c induction motor
IPC: H02P25/04
Filed: 1980-09-03
Abstract: The power factor in an inverter-driven induction motor is held relatively constant at a desired optimum value, despite variations in mechanical loading on the motor, by monitoring the d-c bus current to determine the ratio of real and reactive currents, thereby to detect the actual power factor. The actual and desired power factors are then effectively compared and the resulting error signal is fed back to the inverter's d-c power supply to adjust the inverter output voltage to change the reactive current to the extent necessary to maintain the desired power factor.

Title: Control system for bypass steam turbines
IPC: F01D19/00
Filed: 1981-09-04
Abstract: A control system for a steam turbine operated with a steam bypass system. In the control system, bypass valve control is according to setpoints generated as a function of a combined flow reference (CFR) signal. The CFR signal is representative of boiler outlet flow under all turbine operating phases and is generated by multiplying the sum of the steam admission control valve flow demand and the high pressure bypass flow demand by boiler pressure. An actual load demand (ALD) signal indicative of the turbine demand for steam is produced from the product of the steam admission control valve flow demand and boiler pressure, and is used for intercept valve control. Excessive steam flow in the lower pressure bypass subsystem is prevented by providing an override for the normal control to prevent high heat impact to the condenser and latter stages of the turbine high pressure section.

Title: Watch-dog timer circuit
IPC: G06F11/30
Filed: 1982-09-13
Abstract: A watch-dog timer monitor for the control system of a power plant including a pulse monitor which measures the length of time between successive control pulses from an output port of a computer. In the event that any control pulses exceeds the preselected time interval, the pulse monitor sends a disable signal through a latch to the buffers in the path of the control signals. The buffers instantaneously transition to a blocked condition preventing any subsequent control pulses from reaching the control system of the power plant. A reset button is toggled to reset an initializer which restarts the program in the computer. A start-up delay is also provided to insure that no spurious control pulses reach the control system of the power plant during a warm-up period when the digital logic circuits are settling out.
