Abstract: For a potentiostatically operable, polarographic-amperometric sensor, in particular for biomedical use, wherein a working electrode (5) and a reference electrode (4) are covered by an electrolyte layer (9) which is separated from the medium to be measured by a semipermeable membrane (8), the invention proposes to provide the counter electrode (6) in the form of an external electrode which--for example--can be an outer metal coating surrounding the sensor chip (2) in a three electrode system fabricated as micro-sensor with the integrated technique, and which can be made--for example--of a stainless steel material or of a conductive plastics material.

Abstract: The invention relates to a circuit assembly comprising a block-shaped mount adapted to be equipped with aligned rows of electromagnetically operated fluid power valve-like components, said assembly having internal connection ducts, which on the one hand communicate with the components and the on the other with ducts of a manifold mounted on one of the two end faces of the mount. The block-shaped mount is adapted to be fitted with components on two opposite side faces and there is an electronic circuit board running generally parallel to the direction of the rows of components at a right angle to the side faces of the mount fitted with the components. For making a direct electrical connection between the electronic circuit board and the components gripping terminals are placed on the surface of the electronic circuit board facing towards the block-shaped mount for cooperation with the contact plugs on the components.

Abstract: A colorimetric test tube having a colorimetric indication which includes a simple detection system for testing gases dissolved in liquids. The test tube has an indicator for the colorimetric indication of gaseous substances to be detected and it has an opening covered against the environment to be tested with a hydrophobic membrane which is permeable to the substances whose presence is to be detected and which can be used for indicating the presence of gases dissolved in liquids. The membrane is advantageously sealed with a covering which dissolves upon immersion of the test tube in a liquid.

Abstract: The prior-art CO.sub.2 adsorbent masses used in oxygen-supplying respirators have the disadvantage that they can be granulated only very poorly. The granules have low strength and a tendency to dusting. The goal of the present invention is to produce harder granules which do not give rise to dusting any longer. This is achieved according to the present invention by adding an alkali salt of an oxo acid, preferably sodium hexametaphosphate, to the calcium hydroxide paste prior to the granulation. The present invention is not limited to this salt, but it is also possible to use alkali salts or other oxo acids, such as orthophosphoric acid, sulfuric acid, hypermanganic acid, chromic acid, and vanadic acid. This leads to a substantial increase in the strength to the calcium hydroxide granules without any reduction of their CO.sub.2 binding capacity.
