Abstract: An exterminator for insects, for example mosquitoes, including: a) a container open on an upper side and filled with a water-containing fluid, including an inner wall with a smooth surface descending steeply towards the fluid, b) a cover at a distance above the open upper side of the container, and c) a float in the container, under the cover, and which can move up and down with the fluid level. The float includes a float body which extends above the surface of the fluid and which includes a structure which remains dry in a form of a gauze, net, cloth, screen, grid or fabric, on to which an electrostatic coating layer in a form of a platinum complex-containing silicone composition is provided.

Abstract: A description is given of an exterminator (1) for insects, in particular mosquitoes, comprising: a) a container (2) which is open on the upper side and which is to be filled with a water-containing fluid, having an inner wall with a smooth surface descending steeply towards the water, b) a cover (4) provided at a distance above the open upper side of the container, and c) a float (7) which is provided in the container, under the cover, and which can move up and down with the fluid level, which float has a float body (9) which extends above the surface of the fluid and which comprises or is provided with a structure (10) which remains dry in the form of a gauze, net, cloth, screen, grid or fabric, on to which an electrostatic coating layer in the form of a platinum complex-containing silicone composition is provided, to which one or more powders are adhered which comprise:—a juvenile hormone, such as pyriproxyphene and/or—a fungus, such as Beauveria bassiana, and/or Metarhizium anisopliae, and/or—an intensifyi

Abstract: A method is described wherein DC power is converted into battery charging power by means of an inductor carrying a current which is controlled by a power controller during an adjustable part of a pulse width period. The pulse width period is made adjustable in order to influence the power consumption of the controller which consumes a substantial amount of the total power consumed for controlled DC-DC conversion. Several additional features are provided to improve the efficiency and to further reduce the power consumed by both the converter and the power controller, which provides new uses for a variety of products and appliances having solar cells, such as road studs.

Abstract: A lip-operable spill-proof container (1) comprises (A) an open container base (2), (B) a lid element (4) comprising a lid edge (5) mountable on said container base and with a valve seat surface (7) directed to the inside of the container, perpendicular to a longitudinal axis (8) of the container, and (C) an at least partially flexible valve element (11), comprising (1) a valve body (12), (2) a valve flange (13) extending from the valve body with a valve surface (14) that faces said valve seat surface, and (3) a control element (15). The lid element has a carrier (16) positioned inwards from said lid edge (5) and mounted to said lid edge, and the valve element is provided with a mounting rim (17), that engages the carrier (16) and allows movement of the valve element (11) along the longitudinal axis of the container by elastic deformation of the valve element (11).

Abstract: There is disclosed a coating comprising a silicone composition and a preparation by means of which the surface resistance of the coating is adjusted. The preparation is a platinum complex comprising about 5 ppm platinum metal. Such a coating is highly suitable for use as a pollen coating in filter or screen gauze material and feels good when touched by hand.
