Patent number: 6149407Abstract: When a hot water supply line has to be filled with hot water at all times it requires that the contents of the hot water supply line has to be returned to the hot water heater by a circulator pump. When gas-bubbles form in the hot water supply line, they tend to form a bubble in the suction area of the pump impeller, which leads to an interruption of the flow. In order to prevent this, a circulator pump is used which has a calming chamber in which some of the gases separate, the rest of the air is moved into the spiral channel around the impeller due to an eccentricity of the vortex inside of the impeller. Finally also this gas stream flows into the calming chamber from where the gases leave through a venting valve.Type: GrantFiled: May 24, 1999Date of Patent: November 21, 2000Inventor: Karsten Laing

Patent number: 5810037Abstract: There is disclosed an ultrasonic cleaning apparatus in which the amount of gas dissolved in a cleaning liquid in a cleaning vessel is reduced, thereby enabling a cleaning operation efficiently. The cleaning liquid stored in the cleaning vessel, cleans articles, immersed therein, by a cavitation phenomenon caused by an ultrasonic vibrator. The cleaning liquid is fed to a degassing vessel by a discharge pump through a discharge pipe, and is returned to the cleaning vessel by a supply pump through a supply pipe. Thus, the cleaning liquid is circulated between the two vessels. Gas, dissolved in the cleaning liquid in the degassing vessel, makes bubbles since the degassing vessel is kept to a vacuum, so that the cleaning liquid containing a reduced amount of dissolved gas is stored in the cleaning vessel. Therefore, bubbles are less produced by the ultrasonic vibrator, and the cleaning operation can be carried out efficiently.Type: GrantFiled: July 7, 1995Date of Patent: September 22, 1998Assignee: Daido Metal Company Ltd.Inventors: Takayoshi Sasaki, Kotaro Kashiyama
