Abstract: A fly swatter with a hitting grid and a stem, whereby the hitting grid is joint to the stem by a joint; the hitting grid is rotatable against the force of a spring from a relaxed position about an axis which lies in the plane of the hitting grid and runs perpendicularly to the longitudinal axis of the stem; the hitting grid is lockable in a pre-loaded position with a locking device, and the locking mechanism of the locking device is releasable by way of a trigger, is characterized in that the joint with the turning axis of the hitting grid is assembled between the stem and the hitting grid; the locking device is assembled remote to the trigger; and a string, a wire or different transmission are provided, which transfer a triggering force from the trigger onto the locking device.

Abstract: A solar collector assembly (10) comprising a pipe (18) exposed to solar energy adapted to accommodate a fluid flow in such a way that the solar energy is transferred to the fluid, a heat pipe or any other energy guiding system or absorber; a reflector assembly (12) with a curved reflector (14) for focusing solar radiation in the range of the pipe (18), and an actuator (90,64, 80) for moving the reflector assembly (12) in a way that the solar radiation is reflected in the direction of the pipe (12), is characterized in that means (30, 32) are provided for releasably fixing the reflector assembly (12) to the pipe (18), and the actuator (90, 64, 80) is fixed at the reflector assembly (12) or in the reflector assembly (12).
