Abstract: A polishing disk for a tool for the fine machining of optically active surfaces on spectacle lenses in particular is disclosed, which comprises a support body, to which a foam layer is attached, wherein a polishing film bears against the foam layer. The polishing film is provided with at least one opening in a central region. During machining, the opening ensures pressure equalization and makes liquid polishing agent available from inside the foam layer, as a result of which better rinsing and cooling of otherwise disadvantaged regions of the polishing disk is achieved. As a result, a polishing disk of simple and cost-effective design is proposed, which is much more durable than the prior art while achieving high surface qualities.

Abstract: A lathe for machining optical workpieces, in particular spectacle lenses, comprises a fast tool arrangement and a workpiece spindle arrangement. A machine frame is cast monolithically from polymer concrete and on and in which all the functional surfaces, functional spaces and other cutouts are formed to their exact dimensions during the casting process. The machine frame upper part cast in one piece simultaneously covers the fast tool arrangement and the workpiece spindle arrangement and thus the machine bed in the manner of a covering hood. The machine frame is of compact dimensions, has a very rigid oscillation-damping machine bed and, in comparison with the rapidly moving elements of the fast tool arrangement, has a very large mass with a high center of gravity, which prevents the transmission of disruptive oscillations from the fast tool movement to the machine bed and thus to the workpiece spindle arrangement.

Abstract: A pull-starter for a combustion engine of an engine-powered apparatus having a startup element automatically actuated upon initial pulling of a pull-cord. The pull-cord is attached to and wound around a recoil pulley, routed at least partially around a portion of a movable dampener member, and attached to a handle. The dampener member is biased toward a rest position and a portion thereof is linked to the startup element. The pull-cord is pulled to displace the dampener member away from its rest position, automatically actuate the at least one startup element, and unwind the pull-cord from around the recoil pulley and thereby rotate the recoil pulley in an unwind direction to rotate a crankshaft of the engine via a coupling. At least upon release of the pull-cord, the dampener member and the startup element automatically return to their normal state during engine operation.

Abstract: A compact engine start device of a combustion engine rotary-type carburetor overrides normal operation of a rotary throttle valve to provide a richer mixture of fuel-and-air to start a cold engine. Rotation of a start lever of the start device activates a releasable camming interface coupler causing the throttle lever to rotate about a rotary axis and axially lift partially out of the carburetor at prescribed angular and axial distances. This provides the engine, through a fuel-and-air mixing passage, with a controlled and enriched ratio and volume of a fuel-and-air mixture. Preferably, the start lever has a projecting rod that inserts into a hole in the carburetor body for rotation about an axis orientated substantially parallel to the rotary axis.
