Title: Electromagnetic flowmeter
Inventor: GOTOU YUKIO
IPC: G01F1/58
Filed: 1978-05-24
Abstract: PURPOSE: To achieve the improvement in the reliability of the electromagnetic flowmeter by so disposing electrodes that variations in the flow rate in a pipeline act evenly upon respectively pairing electrodes.  
     CONSTITUTION: Two pairs of electrodes P 1 , N 1 , P 2 , N 2  forming the electromagnetic flowmeter are mounted to a pipeline in which liquid sodium for cooling flows. The electrodes P 1  and N 2  are disposed within the same plane rectangular to the pipeline 5 and the electrodes P 2  and N 1  are disposed within the other plane rectangular to the pipeline 5. Such electrode disposition results in the simultaneous and even action of the fluctuations of flow produced in the pipeline 5 upon the respectively pairing positive and negative electrodes P 1 , N 1  and P 2 , N 2 , hence the potential differences E 1 (t) and E 2 (t) of the respective electrode pairs change nearly perfectly synchronously and the mutual levels coincide nearly perfectly. Hence, the output signals of the same levels may be obtained from two pairs of the electrodes and the reliability of the flowmeter may be improved because the potential differences do not receive the effect of the speed fluctuations of fluid.

Title: Constant quantity pump
Inventor: KUROSAKI YOSHINORI
IPC: F04B53/06
Filed: 1982-04-16
Abstract: PURPOSE:To prevent the occurrence of gas lock when bubbles produced from bubble generating liquid are accumulated in a pump, by opening an intake side valve body having buoyance in the liquid to discharge the bubbles out of the pump. CONSTITUTION:Bubbles produced from liquid in a bore 2 of a casing ascend in the liquid to form a bubble layer on the lower surface of a valve body 11. The valve body 11 loses buoyancy and somewhat descends to open a valve so that the bubble layer ascends in the liquid through the opened valve and passes through a intake side check valve 3 and a gas vent pipe to be discharged into the atmosphere. Since the bubble discharging action is carried out normally automatically, the bubbles are not accumulated in the bore 2 of the casing and a valve chamber 9 so that gas lock do not take place and normal intake and discharge are continued.
