Abstract: An ear-cleaning implement with an applicator for inserting into an ear canal. The distal end region of the applicator is provided with a rounded leading surface. At the proximal end region there is an aperture that receives a post that can be grasped between the fingers. There is a compliant middle region which has an un-deflected configuration before insertion into the ear canal. Before the implement is inserted, it is preferably squeezed between the fingers. During passage into the ear canal, after positioning therein, and upon at least partial withdrawal therefrom, the compliant middle region has at least a partially compressed configuration from which it expands to conform with the ear canal. Upon withdrawal, the implement effectively and safely removes wax from the ear canal.

Abstract: A static screen used upstream of a membrane assembly within a water treatment system has a screening surface with a number of openings distributed over its area. Liquid flows through the screening surface to reach the membrane assembly. Various shapes of screening surfaces are described including three-dimensional bodies with openings at or near their lower ends. Methods for cleaning the screen are described including aeration, backwashing and lowering down the water level in an upstream section by partially or completely draining a tank. Various treatment systems or process designs incorporating the screen are described. Screen elements may be made in two or more parts comprising a supporting structure and a separation layer and may be mounted on a conduit or pan.

Abstract: This invention concerns a structural sky roof which allows structure complexes composed of one or several houses, parks, gardens, playgrounds, sports fields, shopping malls, parking lots, school-like structures to be protected against all adverse atmospheric effects originating from the sky and which covers all those structures almost like an umbrella.

Abstract: A static screen used upstream of a membrane assembly within a water treatment system has a screening surface with a number of openings distributed over its area. Liquid flows through the screening surface to reach the membrane assembly. Various shapes of screening surfaces are described including undulating panels and geometric shapes. Methods for cleaning the screen are described including aeration and backwashing. Various treatment systems or process designs incorporating the screen are described.
