20120318376 | CLEANING APPARATUS, RADIATION SOURCE MODULE AND FLUID TREATMENT SYSTEM - There is described a cleaning apparatus for a surface (e.g., a radiation source assembly) in a fluid treatment system. A preferred embodiment of the cleaning apparatus comprises: a wiping element for contact with at least a portion of the surface; at least one cutting element connected to the wiping element for cutting elongate debris in contact with the surface; and a motive element for moving the carriage between a first position and a second position. This preferred embodiment of the present cleaning apparatus is particularly advantageous for removing elongate debris from one or more radiation source assemblies disposed in the fluid treatment system. The approach utilized in this preferred embodiment of the present cleaning apparatus is to include at least one cutting element which is moved along the exterior of the radiation source assembly. The cutting element is connected to a wiping element that is translated between a first position and a second position. As the wiping element is moved from the first position to the second position, it will tend to push the elongate debris toward a distal portion of the radiation source assembly. During this translation step, it is possible that some of the debris may be cut by the cutting element. As the wiping element approaches the distal portion of the radiation source assembly, it will tend to clamp down on the elongate debris and, as the force of movement is continually applied, the cutting element will cut the elongate debris. Once the elongate debris is cut, it will more readily fall away from the radiation source assembly and this action is facilitated by a flow of fluid past the radiation source assembly. | 12-20-2012 |

A valve fitting at the distal end of the hose is sized for engaged receipt of a male valve stem, such as a Schrader valve. Another embodiment of the invention includes a valve fitting extending through top of the cap. A further embodiment of the invention includes an upper component and a lower component forming the cap, wherein the upper component is securable to a nozzle of a garden hose and the bottom component is securable to an open-ended drain line extension. | 03-05-2015 |
20150090347 | FLUID VALVE, IN PARTICULAR A RETURN VALVE FOR A PAINTING SYSTEM - Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side. | 04-02-2015 |
20150362001 | COOLANT SUCTION DEVICE AND MACHINE TOOL - Provided is a coolant suction device that can collect a coolant remaining in a supply pipe while preventing an ejector from breaking down. The coolant suction device comprises: a gas supply source ( | 12-17-2015 |
20160097148 | WASHING MACHINE DESCALER INTRODUCTION APPARATUS - A washing machine descaler introduction apparatus for introducing a descaling agent to the water inlets of a conventional washer and dryer at a controlled rate comprises a dispensing bag with an attached dispensing valve assembly and an attachable diverter. In use, the dispensing bag, containing of a descaling agent, is hung from an elevated position above a convention washing machine with the water inlet conduits of the washing machine each connected to one of two outlet tubes of the diverter. Once a hole is opened for ventilation, the valve handle is moved from the closed position, partially or fully opening the valve assembly's outlet pipe, thereby enabling the descaling agent to exit the bag and be directed into the hot water inlet conduit and the cold water inlet conduit at a rate that is controlled by how unobstructed the outlet is with respect to the closing member. | 04-07-2016 |
