  • Patent number: 9004017
    Abstract: A water heater includes a bypass that is formed, on the side of a water supply pipe, branching from a main water path and bypassing a part of the main water path, and a flow path switching unit (a valve and a stepping motor) that is formed at a branching portion of the main water path and the bypass. The flow path switching unit is controlled by a controller and that can selectively switch a flow path between the main water path and the bypass. A microbubble generator generating microbubbles is provided on the bypass, the microbubble generator including a water agitator portion, a compression portion and a decompression portion. When the controller determines that scale has built up, the flow path is switched to the bypass by the flow path switching unit, and water containing microbubbles is caused to flow inside the water heater.

  • Patent number: 8956466
    Abstract: A process for treating a substrate comprised of sorptive material is provided herein. The sorptive material may be an absorbent synthetic material such as polyester. The material is designed to be used for cleaning surfaces in an ultraclean environment. The process first comprises unwinding a roll of sorptive material as a substrate into a cleaning system. The cleaning system utilizes several sections. These include a pre-washing section, an acoustic energy washing section, and a drying section. Preferably, the process of moving the substrate through the cleaning system is continuous. The acoustic energy washing section employs one or more acoustic energy generators. In one aspect, the process also includes cutting the substrate into sections to form wipers after moving the substrate through the drying section. Thereafter, the wipers are placed into a bag and the bag is sealed. An integrated treating system for a sorptive material is also provided herein.

  • Publication number: 20150020845
    Abstract: A cleaning device and method remove a lubricant from the rolls of a roll stand. To achieve economical and efficient cleaning of the rolls, the cleaning device includes at least one ultrasonic generator for generating ultrasonic waves, the ultrasonic waves being routed to the surface of the rolls by cleaning water; and a supply line for the cleaning water. The supply line is a branch of a cooling water circuit for the roll stand, enabling the water consumption for the roll stand to be kept constant during the cleaning phase. The water is merely redistributed in that a portion of the cooling water is supplied to the cleaning device. This creates the advantage of the roll temperature rising slightly, with the result that the cleaning performance is supported by the higher roll temperature at which the lubricant is better released from the surface of the roll.
