Abstract: The cooling system has its compressor realised as an electromotor with multiplexed polarity.  The first polarity configuration includes two windings, that is, a start winding and a main winding.  The second polarity configuration is the main winding alone.  The motor runs on a two-pole winding at max. power and on the single-pole winding at reduced power.

Abstract: The binocular telescope with internal focusing and articulated bridge contains as a joint focusing mechanism two setting rings which can be coupled and which are arranged co-axially on a central axis. In uncoupled condition each setting ring is allocated to a focusing member of a tube, so that focusing can be done independently from each other. In coupled condition both focusing members are shifted jointly by actuation of each of the setting rings. Thus, an unintentional adjustment of the relative positions of the two focusing members is impossible, and focusing of each focusing member in succession is possible.
