Abstract: A system includes an electric appliance, which is operated with replaceable and rechargeable batteries, a charging station and two or more battery units. The charging station has two or more receptacles for holding and charging the battery units. A first coupling is provided between a battery unit and the appliance and a second coupling is provided between a battery unit and the charging station such that a battery unit connected to the appliance can be uncoupled from the appliance by one-handed operation and can be coupled to the charging station for charging by one-handed operation. Similarly, a battery unit connected to the charging station can be coupled to the appliance and uncoupled from the charging station by one-handed operation.

Abstract: To provide a squeeze bottle with reduced pressing force required to delivery a liquid, and particularly a squeeze bottle wherein the pressing force is reduced to such an extent that allows easy control of the discharge of liquid drops even when a valve operated by the liquid pressure is provided. In a squeeze bottle comprising the bottle body 10 for containing a liquid, and a neck 11 that leads to the opening end 10a of the bottle body 10, the bottle body 10 has a bellows 12 which is contracted and expanded in the direction y generally perpendicular to the direction x of delivering liquid. The bellows 12 has a plurality of pleated portions 13 disposed in the direction of delivery x. The pleated portions 13 are disposed at intervals in the direction of contraction y. Further, the width of the convex edge of the pleated portion 13 in the direction of width Z, that is, the distance between the both edges 14, is made to decrease from the middle to the both ends in the direction of contraction y.

Abstract: The invention concerns a method and arrangement for disconnecting consumers who are connected to a voltage source, specially a direct voltage source. For the purposes of the present invention direct voltage systems are, for instance, the well-known mobile equipment driven by solar cells, primary or secondary batteries. The present invention is based on the knowledge that several consumers are often present in a voltage system, apart of which can be disconnected immediately when one or several conditions for disconnection are fulfilled, while another part of the consumers should be gradually disconnected due to technical safety reasons or psychological aspects. According to the invention consumers connected to a voltage source can be disconnected in two steps, that is, the power passing through the consumers is reduced, for which a slow regulation is offered, and later the power passing through the rest of the users is disconnected.
