Title: Method and device for measuring content of clay in molding sand
Inventor: UCHIMURA KATSUJI
IPC: B22C5/00
Filed: 1982-01-13
Abstract: PURPOSE:To measure the content of clay in molding sand mechanically, automatically and continuously with high accuracy by supplying electric current through the molding sand between the electrodes inserted into the molding sand under moving and detecting the electric resistance value at that time. CONSTITUTION:The lower parts of electrodes 3, 3 mounted with electric insulators 4, 4 to a supporting member 5 mounted to a stationary frame 6 are dipped into molding sand which moves on a belt 1 of a belt conveyor while the sand is regulated with guiding members 2, 2. Voltage is applied between the electrodes 4 and 4 to run electric current through the molding sand. The total electric resistance value R of the molding sand when the current flows is measured; at the same time, the temp. and moisture of the molding sand are measured with a tamp. sensor 11 and a moisture measuring sensor (not shown). From these measured values, the electric resistance relating to the content of clay is determined by subtracting resistance factors such as temp., moisture, intrinsic values in the molding sand and the like from the above-mentioned value R by an operator (not shown), and further the content of clay is calculated.

Title: Method and device for pressure adjustment of pressure fluid
Inventor: SAITO TADASHI
IPC: G05D16/20
Filed: 1989-01-11
Abstract: PURPOSE:To provide possibility of returning varying pressure in a pump, etc., into a specified range certainly and quickly by increasing/decreasing the frequency of power supply with an adjusting mechanism, which can impress DC voltage to the power supply, and thereby adjusting the pressure of a pressure fluid. CONSTITUTION:In case a pressure signal generated by a signal transmitter 4 exceeds the upper limit value, signal is fed to one of the relays 6 of an adjusting mechanism A, while in case lower than the lower limit value, is fed to the other relay 6', and the resistance value of a variable resistor 8 is changed by operating a small-sized motor 7 in appropriate direction. Thus the DC voltage generated thereby is varied, and resultant DC voltage is applied to a power supply 1 for controlling its frequency. If this frequency adjustment in such a constitution returns the pressure into the specified range, generation of pressure signal by a pressure signal generating mechanism 4 is stopped immediately for maintaining within the specified range, wherein eventual generation of change in the rate of flow will actuate a control mechanism immediately so as to return the pressure into the specified range in a minute time.
