Abstract: An improved pool cleaner hose assembly is provided for use in drawing water under a negative pressure from a manually operated pool cleaner device to a water filtration system for swimming pools and the like. Improvements relate to enhancements in the view of the operator on debris at the bottom of the swimming pool during cleaning operation. The hose assembly is coupled between the cleaner device and filtration system. An improved cleaner hose assembly comprising a conventional extruded plastic hose and a plurality of weights attached along the length of the hose to orient the hose at the lowest profile on the pool floor whereby imparting minimum disturbance to the water surface and enhancing the view of the operator.

Abstract: Apparatus for cleaning particulate material including coal particles and dust from a flexible belt of the type which is adapted to transport material such as coal on its material-supporting surface and which is of a composition which has and is subject to the development of surface cracks. The belt is advanced lengthwise along a predetermined path on its return run with the material-supporting surface on the underside. A scraper blade is supported crosswise of the belt in scraping contact with the material-supporting surface of the belt as the belt is advanced. Liquid is sprayed against the material-supporting surface of the belt and into the surface cracks adjacent to the point of contact of the scraping edge. The liquid is sprayed against a surface of the blade to be deflected into the cracks and also to maintain the blade in a clean condition. A backing member holds the belt down in contact with the scraper blade.
