Abstract: TITLE OF THE INVENTION:                     DEVICE FOR MONITORING OF CORROSION             ABSTRACT OF THE DISCLOSURE           A device for the monitoring of corrosion, for example, of heat exchanger tubes, consisting of one or several test tubes which are attached at an easily accessible point.  These test tubes are made of the same material as the heat exchanger tubes to be measured.  The corroding medium, in general cooling water, flows through the test tubes with the same speed and with the same pressure drop as in the heat exchanger tubes.  The device according to the invention permits the monitoring of the corrosion with different measuring methods.  For the purpose of monitoring localized corrosion, a reference electrode and a millivoltmeter are attached to the test tube, if only one is used, whereby the corrosion potential is measured in the test tube which is identical with the potential in the heat exchanger tubes. For the monitoring of corrosion-caused reductions in the cross-sections thereof,the electrical resistance of the test tube is measured.  The monitoring of the corrosion-caused surface removal is based on the measuring of the polarization resistance.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved method is described for the continuous shielded arc melting of calcine in an electric arc furnace to obtain molten slag, underlain by molten metal.            The furnace is so operated that the major portion of the total energy supplied thereto is released in the arc, and the minor portion in the molten bath.  The improvement consists of adjusting the electrical energy released in the bath, directly to obtaining a required active bath area calculated by means of the rate of change in the volume of the slag and indirectly to the silica:magnesia ratio in the slag.  The optimum range of active bath area is derived from conditions required for the safe and continuous operation of the furnace, in order to protect the furnace walls from slag erosion and to avoid excessive electrode movement.

Abstract: Abstract A reflective laser recording and data storage medium, for direct reading after writing, formed from a photosensitive silver-halide emulsion wherein a sur-face latent image exposure on the recording area forms a depthwise gradient of silver nuclei.  A single step negative silver diffusion transfer process is used to develop silver nuclei of the latent image and dissolve unexposed silver halide elsewhere, forming silver ion complexes.  These complexes are transported by diffusion transfer to the developing silver nuclei sites where silver is precipitated and adsorbed to form a high con-centration of non-filamentary particles at a surface of a low melting temperature dielectric matrix which is highly reflective of light and electrically non-conducting.
