Title: Gas generator for curing sand mold
Inventor: MURATA YUTAKA
IPC: B22C9/12
Filed: 1994-04-08
Abstract: PURPOSE:To ensure atomization of a hardener and to make it possible to conduct gushing according to the curing state of a sand mold by communicating the front end of a branch pipe with the base end of an air ejection nozzle and providing this branch pipe with a flow rate regulating valve or a reducing valve and stop valve. CONSTITUTION:A teeming pump 5 operates to lift a hardener 4 in a hardener tank 3 and to teem this hardener 4 from a teeming nozzle 2 via a check valve 7 in the state of closing respective solenoid operated stop valves 10, 13, 16. The solenoid valves 13, 16 are then opened. As a result, compressed air is reduced in pressure by the reducing valve 17 of the branch pipe 15 and is blown from the air ejection nozzle 9 toward the front end of the teeming nozzle 2, by which the hardener 4 is forcibly atomized. The compressed air reduced in pressure by the reducing valve 14 for low-pressure regulation is made to flow from a bypass pipe 12 to a gas piping 1 simultaneously therewith to feed the atomized hardener to a molding box. As a result, the low-pressure compressed air is fed to the surface of the sand mold in the molding box, by which the sand mold is successively hardened from its surface without damage.

Inventor: DEGUCHI TAKASHI
IPC: C07C11/09
Filed: 1981-06-19
Abstract: PURPOSE: To separate isobutylene and recover methanol from a side cut stream, etc. simultaneously, by decomposing methyl-tert-butyl ether recovered from a spent BB fraction in the liquid phase in the presence of an acidic catalyst, and distilling the reaction solution under heating.  
     CONSTITUTION: Methyl-tert-butyl ether in the liquid phase is decomposed in a reactor 1 in the presence of an acidic catalyst, preferably sulfonic acid type ion exchange resin, and the resultant reaction solution is then heated to feed the generated steam to a distilling column 2 directly connected to the reactor 1. Isobutylene is mainly separated and recovered through a pipe (B) from the top of the column 2 while carrying out the suitable reflux. On the other hand, methanol is recovered through a pipe (C) by washing a side cut stream and/or bottoms of the distilling column 2, and distilling the water containing the methanol in a distilling column 4.  
     EFFECT: Effective utilization of the spent BB fraction.

Title: Sensor circuit
Inventor: ITOU HISATSUGU
IPC: G01D5/16
Filed: 1978-08-05
Abstract: PURPOSE: To highly accurately detect the value of a sensor during the operation of a meter by applying a constant current to a sensor resistor which is connected with the meter to be driven at a constant voltage by a bimetal.  
     CONSTITUTION: When a switch 2 is closed, a current is supplied through the switch 32 of a closed meter 3 from a power source 1 to a voltage adjusting bimetal 31 and an indicating bimetal 33. The bimetal 31 turns on and off the switch 32 in accordance with the voltage of the power source 1 so that the meter 3 effects the drive at the preset voltage even in case the supply voltage of an automobile or the like is high. If the closure of the switch 32 is detected by the detecting circuit 42 of a sensor circuit 4, the constant current from a constant current source 41 is supplied a variable resistance sensor 34 which is in series with the bimetal 33. Thus, the both terminal voltages of the resistor 34 are detected in a high accuracy during the operation of the meter 3 by a potential detector 43 of the circuit 4. Incidentally, if the potential of the capacitor to be charged with the constant current output is compared with the detected potential of a runner electrode, the digital detection can be accomplished with the use of the digital detection.
