Abstract: An analyzer system has a base housing (1) and a sample tray (4) with at least two holding accommodations (5) for containers (32) of samples that are to be analyzed. The sample tray (4) is movably supported on the base housing. A drive mechanism (2) inside the base housing advances the tray (4) so that the containers (32) move in steps along a prescribed track to an analyzer module (16), where the samples are subjected to an analysis. A lid-opening device (50) is arranged along the prescribed track at a place that the sample containers (32) reach before they arrive at the analyzer module (16). The lid-opening device (50) serves to open lids (32?) of a predetermined shape and thickness (H) by which the sample containers (32) may be covered. The lids (32?) are preferably made of a non-magnetic material containing a magnet-anchor element.

A lid-opening device (50) is arranged along the prescribed track at a place that the sample containers (32) reach before they arrive at the analyzer module (16). The lid-opening device (50) serves to open lids (32′) of a predetermined shape and thickness (H) by which the sample containers (32) may be covered. The lids (32′) are preferably made of a non-magnetic material containing a magnet-anchor element.

Abstract: A hydraulic brake for bicycles consisting essentially of a brake lever fastened on the steering column of a bicycle which works on a master piston movably arranged in a master cylinder, wherein the chamber in the cylinder is filled with hydraulic fluid, which is conducted by way of a hydraulic tube into the chamber of a working cylinder, in which a main piston is movably arranged, which works on the brake shoes of the bicycle. Along with lower manufacturing costs, there is easy interchangeability and a good reliability in servicing the brake. A single working cylinder is fastened above the fork of the bicycle and the main piston is connected with a control head, over which a traction cable is directed, which works on the usual brake shoes.
