    摘要: A varifocal object selectively focusable upon a normal range of object distances and a substantially shorter macro range can be supplemented by a negative component of one or more lenses whose focal length is less than the depth of the macro range and which forms a virtual image of a nearby object on the object plane of the objective when the latter is adjusted to a predetermined closeup position. A correlating linkage between a seat for the supplemental component and a control member designed to establish the closeup position serves to index the control member in that position or to prevent the emplacement of the supplemental component if the objective is in a different position.

    摘要: In an automatic play compensation arrangement for a cable-operated parking brake including a brake operating element and a cable extending between the brake operating element and a vehicle brake for actuating the vehicle brake, a support bracket is mounted for movement with the brake operating element and has a spring-loaded clamping lever supported therein through which a cable end extends and by which the cable end is firmly engaged with the support bracket when the brake operating element is actuated, and a spring is provided for tensioning the cable when the brake operating element is in a brake-releasing rest position.
