Abstract: A device for picking up balls or golf balls (10) is disposed in the region of the grip (11) of a club (12). It includes several holding elements, which are displaceable under the effect of at least one resilient element from a rest position on the grip into an actuatable position in which they are capable of picking up the golf ball. By the holding element being at least two gripping arms (13, 14), which are fitted into each other in the rest position under the effect of at least one resilient element, a compact device for picking up that is simple to operate is created.

Abstract: A golf club has a device for the alternate picking up and simultaneous placing down of a marker on the green or respectively the placing down of a golf ball through the intermediary of a mechanical pivotal mechanism, wherein both the picking up of the ball and the simultaneous placing of the marker as well as the placing of the ball and the picking up of the marker from the green is effected by the player whilst in a substantially standing position. By the mechanical pivotal mechanism being formed by a pivotally mounted rocker for the alternate picking up of ball and marker and the picking up and placing down of the marker being effected in a guided manner, the ball is picked up and the marker simultaneous placed down or respectively the ball is placed and the marker picked up in a correct manner without the player needing to bend down.

Abstract: A method for manufacturing a flat illumination unit provides light guide channels in the form of transparent rods arranged in lines on the upper side of a plate. The upper side of a plate is coated with a casting compound and, after hardening of the casting compound, the plate is eroded from the opposite side until only the light guide channels remain respectively surrounded on three sides by the casting compound and therewith form a film.

Abstract: A semi-automatic coarse-fine focusing apparatus for microscopes adjusts the focus of a microscope through rotation of a shaft which rotates a pinion that drives a rack to reciprocate. The rack carries a specimen being observed by the microscope. The shaft which rotates the pinion is in turn driven by a gear that is meshed with a helix formed on a cylinder by a helical thread disposed therearound. The helix is non-rotatably mounted on another shaft that includes a knob which is manually turned to turn the helix and thus rotate the gear for coarse adjustment. The helix is preferably rigidly mounted on the shaft and the shaft is slidable. One arm of a bell crank engages an end face of the helix to reciprocate the helix and thus rotate the gear for fine adjustment. The other arm of the bell crank is engaged by a cam which pivots the bell crank according to the position of the cam. The position of the cam is determined by an electric motor which is preferably controlled by signals that vary with image contrast.
