Abstract: ABSTRACT       The present invention provides a process for the production of reagent solutions containing a plurality of components for analytical purposes, wherein the individual components of several differently composed reagents are each introduced into a solid, proportionable carrier material in easily redissolvable form in such an amount that each part by volume or weight of the carrier material carries a definite amount of one reagent compon-ent, the carriers of the components are brought together in a magazine-like manner and, for the production of a particular reagent, from all carriers which carry a component of the reagent, there are simultaneously taken off the amounts corresponding to the required amounts of the components, which are introduced into a reagent solution, in order to dissolve the components.     The present invention also provides a device for the production of reagent solutions for analytical purposes which contain a plurality of components, com-prising a magazine, which contains a plurality of carrier materials, each of which carries, per unit volume or weight, a definite amount of an individual component of a reagent, a proportioning device which, from several carrier materials, enables definite amounts to be measured off and separated off, preferably simultaneously, a conveyor device for transporting the separated off amounts of carrier to a solvent container and a control device which controls the proportioning device for each desired reagent composition.

Abstract: A METHOD AND APPARATUS FOR UNIFORMLY DRYING A CONTINUOUS WEB OF CELLULOSIC FIBERS               Abstract of the Disclosure A method and apparatus used in the uniform drying of a continuous web, such as a sheet of paper or paperboard.  A newly formed web of paper of wet cellulosic fibers and the necessary additives is initially directed through a press section where excessive water is squeezed from the web to reduce its moisture content to about 50-80 percent, by weight, for subsequent passage through a dryer section wherein the moisture content is further reduced to anywhere between 3 and 15 percent, depending on the quality of the paper being processed.  The moisture content profile of the nearly dry web of paper is constantly monitored adjacent the discharge end of the dryer section for dry streaks which occasionally occur in the web.  Moisture is added accord-ingly to the web when the web is relatively wet and has a moisture content of at least 25 percent to eliminate further dry streaks and provides a paper product which has a uniform moisture content.

Abstract: ABSTRACT OF THE DISCLOSURE A process for forming a WC-Mo C solid solution alloy starts by first intensely milling, such as dry attritor milling, Mo and W metal powders, followed by a homogenization heat treatment of about 1400° to 1500°C to form an Mo-W solid solution alloy. The Mo-W solid solution alloy is then crushed to form a fine powder and mixed by ball milling with the appropriate amount of carbon plus cobalt.  The milled alloy powder is then heated at approximately 1100° to 1400°C to form the desired WC-Mo C alloy.

Abstract: ABSTRACT    To improve the aeration of the water, for the benefit of plants and animals living therein, and to combine the aeration with the cleansing of the water by a biological cover, one or several circular disks are rotated in a clarifying reservoir about a horizontal shaft.  These carry at their circumference annularly bent funnels which extend in part above the water surface and continuously converge in direction from the inlet opening to the outlet opening.  Above the water surface air enters through the inlet opening into the funnel and below the water surface water enters into it.  Because the funnel converges continusouly, both water and air are accelerated and compressed in the funnel.  The compression assures that the amount of oxygen which is soluble in the water, and can be accepted by the same from the air, is substantially increased.          The biological cover forms on the disks and on the outer surface of the funnel.

Abstract: ABSTRACT         A rotary nozzle of the type which is attached to the pouring nozzle of a ladle which contains molten metal for transporting or pouring purposes or in the teeming hole of a converter so as to allow the outflow of molten metal is dis-closed.  The rotary nozzle includes a fixed plate brick, a fixed plate supporting frame and a rotor mounted on the outer periphery of the supporting frame by way of a bearing, and a sliding plate supporting frame holding a sliding plate brick secured to the rotor by a hinge so as to be opened and closed.          Hooks and springs are attached to the hinge and other hinges to thereby prevent lowering of the sliding plate brick and securely fasten the sliding plate supporting frame to the rotor.  This ensures the elimination of preliminary setting which has heretofore been required, easy maintenance, inspection and change of the sliding plate brick, a considerable reduction in the time required for these works and prevention of the molten metal leakage.

Abstract: ABSTRACT       An ignition system is provided for creating a continu-ous stream of high voltage pulses to each spark plug over a predetermined period of time as controlled by the distributor.          Below the transformer core is positioned a switch incorporating a plate which is magnetically attracted to the transformer when a current flows through the windings. When the contacts of the contact breaker open the supply from the battery to the trans-former core is cut off so that the switch closes under the bias of a spring due to the collapse of the magnetic field created in the core.  Closure of the switch restores the circuit from the battery to the primary and secondary windings of the transformer and thus during the whole period that the contact breaker is open the switch will intermittently open and close, resulting in the application of a rapid series of high tension pulses to the respective spark plug.  This gives greatly improved operating characteristics for the engine.  The switch can be isolated from the circuit by a push button switch if desired.
