| 20090100618 | BUILDING EXTERIOR WALL CLEANING APPARATUS - A building exterior wall cleaning apparatus includes a housing being provided on a top with a set of external hoisting hangers, at a front side with a spray unit, and at a rear side with at least one gas producer; at least one cleaning unit being rotatably mounted to a front side of the housing next to the spray unit; and a driving unit being mounted in the housing and connected to the at least one cleaning unit. The at least one cleaning unit may be tightly pressed against a building exterior wall by airflow produced by the gas producer and to clean the building exterior wall in one stroke of the cleaning unit, so as to enable safe, efficient, automated and unmanned building exterior wall cleaning operation. | 04-23-2009 |
| 20110232013 | CLEANING IMPLEMENTS, CLEANING MATERIAL COMPONENTS, AND RELATED METHODS - The invention provides cleaning implements that include head components comprising cleaning surface components and cleaning material support components. The cleaning material support components typically include cleaning material receiving areas that communicate with the cleaning surface components. Cleaning material receiving areas are generally configured to receive cleaning materials that are movable to and/or from the cleaning material receiving areas to extend over at least portions of the cleaning surface components. The invention also provides cleaning material components that include cleaning material support structures and cleaning materials. Related methods are also provided. | 09-29-2011 |
| 20120110760 | Rotary screen cleaner - The present invention is to provide a rotary screen cleaner which includes a housing, a rotating element, a cloth supporting block and a cleaning cloth. The housing defines a receiving space therein and is formed with an opening on one side. The rotating element is pivotally provided in the housing and has one end outside the housing for being turned by a user. The cloth supporting block is made of an elastic material and is fixed in the receiving space, and has one end passing through the opening and extending out of the housing. The cleaning cloth is made of an elastic material and wrapped around the rotating shaft and the cloth supporting block. Thus, the user is able to use the cleaning cloth partially exposed outside the opening to clean a screen, without causing the screen to be scratched by the cleaner. | 05-10-2012 |
| 20120131756 | Hygienic Door Handle System and Method - The invention provides a system and method for self-cleaning a door handle ( | 05-31-2012 |
| 20140059789 | Apparatus for Cleaning a Semiconductor Substrate - An apparatus for processing a substrate is provided. The apparatus includes a solid material having a support side and a contact side. The contact side has an outer surface, and the outer surface is configured to become softer relative to a remainder of the solid material when exposed to an activation solution. The apparatus includes a support structure configured to support the solid material from the support side of the solid material, such that the contact side of the solid material is oriented to face a surface of the substrate, when the substrate is present. Also provided is a gimbaled structure connected to the support structure. The gimbaled structure enabling the outer surface of the contact side to substantially align in a coplanar arrangement with the surface of the substrate, when the substrate is present. A force application structure is coupled to the gimbaled structure. The force application structure is configured for moving the solid material toward and away from the surface of the substrate, when the substrate is present, and further configured for applying a force that presses the outer surface of the solid material against the surface of the substrate, when the substrate is present. | 03-06-2014 |
| 20140259481 | OPTICAL CONNECTOR CLEANING TOOL - An optical connector cleaning tool includes a cleaning body that is fed and moved, a feeding mechanism that performs supply and take-up of the cleaning body, a housing body that houses the feeding mechanism, an extension portion that extends from the housing body, comprising a plurality of distal end tube portions, and an outer tube body through which the plurality of distal end tube portions pass, including a plurality of distal end openings from which the plurality of distal end tube portions are extended; and a head member that is passed through each of the plurality of distal end tube portions and that presses the cleaning body against the joining end face at the distal end of the extension portion. | 09-18-2014 |
