Title: Weighing controller for air transportation
Inventor: YOKOI HIROSHI
IPC: G01G13/24
Filed: 1994-03-10
Abstract: PURPOSE:To obtain a weighing controller with limited weighing errors by providing a sensor or the like to detect the number of revolutions of a rotary feeder to correct a set value of a constant amount setter. CONSTITUTION:When a rotary feeder 102 receives a start command signal S2, a rotary blade is driven to send out bulk solid material from a stock tank 101 while a transmitter (sensor) is provided to generate a signal S1 proportional to the number of revolutions of the rotary blade. A blower 103 is a generation source of compressed air for transporting the bulk solid material. An indicator 104 receives the signal S1 to display the number of revolutions per unit time and a moving mean computing device 105 calculates a moving mean of the number revolutions per unit time. A leakage value computing device 106 receives an output signal of the computing device 105 to calculate a leakage value. When a signal of a weight sensor 108 reaches a set value, the constant amount setter 109 outputs a delivery stop signal S2 to feed a specified amount of the bulk solid material to a reservoir tank 107. The set value is corrected based on the leakage value calculated with the computing device 106.

Abstract: PURPOSE:To improve the state of combustion, by providing a changeover valve, which is opened or closed depending on load, and a rotary valve, in an oil pressure line for moving the fulcrum of a rocker arm up and down, to decrease the quantity of valve life as to the low load, to augment the inflow velocity of a mixture. CONSTITUTION:When load is high, a flow meter 11 detects that the flow rate of intake air is large, and a detection signal is sent from the flow meter to a solenoid 7' to close a changeover valve 7 to apply oil pressure to a cylinder 12 to move a pivot 3 in a direction A. When the load is low, the changeover valve 7 is opened, and a rotary valve 8 is opened synchronously with the rotation of a cam shaft 1 to put a drain pipe 15 in a connected state. As a result, the oil pressure in the cylinder 12 drops, and the pivot 3 is moved in another direction B by the reactionary force of a valve spring 4. For that reason, the quantity of the lift of a valve 5 is restricted in such a manner that the quantity of the life is decreased at and around the maximum lift.

In this case, either of Tr16 or 17 can be in peaking, but the amount of peaking by Tr16 is small and it can be considered that most of peaking is made at Tr17. When the diameter of the coaxial cable is small, the selection is made to the terminal B suitably selecting the coil 65 and the damping resistor 66. When the cable length is short, selection is made to the terminal A not using the coil.
