Abstract: A chemical-mechanical applicator for treating and cleaning surfaces in the domestic, automotive aftermarket, personal care and cosmetic sectors. The applicator wets, agitates/massages, and scrapes off residue leaving a surface dry and clean without soiling users hands. The applicator is a blade like device integrated with a dispenser device that is coupled to one or more reservoirs from which fluids are dispensed onto a surface. The blade carries a multiplicity of pads interspersed with scraper edges. The pads are used for rubbing and swabbing off. The scrappers are used for scraping and drying by squeegee action, the collected up used fluids retained within the blade.

Abstract: A surface treatment tool (213) formed from a thin sheet of flexible material, typically a polymer, shaped to store and dispense fluid, scrub, abrade, scrape off and retain debris including particulates from treated surfaces. The tool is useful for cleaning in domestic, industrial, cosmetics, personal or medical care fields. The tool comprises an array (214) of closely spaced hollow mushroom shaped protrusions (212) that store (after a bottom sheet is added that is not shown) then release fluids during rubbing via perforated faces (214), the upstanding mushroom shapes (211) carrying soft rubbing faces (214) with harder scraper edges (217) constitute the operable face with gaps (215) between faces leading into a sunken labyrinth (216) into which loosened debris are scraped up and retained.

Abstract: It is already common in many devices like spanners or pipe wrenches for the pressure between the gripping faces and gripped faces to be related to the torsional load that is applied to turn the gripped object. In these apparatus the grip can be made to relax automatically as the load is removed. The invention relates to improvements in such devices, and to novel designs of mechanical coupling devices that utilise this basic idea. More specifically, the invention firstly proposes a method of improving the performance of an object-gripping tool of the cam-operated gripper-element type, in which method there is applied to the gripper surface a friction-enhancing chemical.
