Abstract: ABSTRACT OF THE DISCLOSURE         Due to increasing demands for steel to be used for construction such as buildings, pressure vessels, pipe lines or the like, various kinds of high tension steels, particularly steels suitable for welding have increasingly been developed.         Heretofore, proposed methods of making such high tension steel have relied on so-called cold rolling and/or rolling followed by quenching and tempering, however, these conventional steels have suffered from drawbacks such as a tempering step indispensable after quenching, softening of welded zone and lack of uniformity in the metal structure in the direction of plate thickness.         A compositional feature of the new method resides in addition of minor amounts of Ti and B along with Nb as contributing to grain refining or precipitation hardening elements in addition to limited amounts of other ingredients such as C, Si, Mn, S, Al and N.         Further addition of at least one of V, Ni, Cu, Cr, Mo, Ca and REM also acts to improve the properties of the steel.          The steel prepared to have the aforesaid composition is subjected to controlled heating, subse-quent rolling under prescribed rolling reduction ratio, temperature for terminating rolling and to a specified cooling rate.         The steel plate thus processed has a structure having fine bainite grains alone or a duplex grain

Abstract: APPARATUS FOR AGITATING AND PUMPING                   A LIQUID SLURRY               Abstract of the Disclosure An apparatus for agitating and pumping a liquid slurry, such as liquid manure slurry.  The apparatus includes a pump which is adapted to be positioned within the lower end of a pit that contains the slurry, and the pump is operably connected to a motor which is located above the pit.  The motor-pump unit is mounted for sliding vertical movement on a fixed column and can also be rotated horizontally relative to the column to vary the position of the outlet of the pump during agitation of the slurry.  The apparatus also includes a means for tilting the motor-pump unit with respect to the fixed column.  When the pump is raised to a location adjacent the top of the pit, the motor-pump unit can be titled in a vertical plane to move the pump out of the pit to a position where it can be repaired or maintained.

Abstract: ABSTRACT OF THE DISCLOSURE A method of operating a high voltage DC transmission system with any number of transformer stations.  Transformer stations which operate as rectifier stations operate with voltage regulation having a current dependent control input.  In the range from 1 per unit to 1-.delta. per unit of rated voltage, a hard current limit is in effect, and in the range from 1-.delta.  per unit to 1 - .delta. - .epsilon. per unit rated voltage, the current limiting value is reduced to a minimum current, where .delta. and .epsilon. are preselected fractions.  Transformer stations which operate as inverter stations principally operate with current regulation and in the voltage range from 1 per unit to 1-.delta.  per unit of rated voltage, the maximum desired current value is reduced from rated current value down to zero.

Abstract: ABSTRACT       Improvements to Information Display Devices A display device of the matrix type utilises coincident current selection of display elements by the provision of row conductors (R) activating row electro-magnets (D) and column conductors (C) activating column electromagnets (H).  Each display element includes a rotatable vane (S) which is stable in open and closed positions and a permanent magnet (M) co-operates with the electromagnet (D) to urge the vane (S) into the appropriate position.         Bar (L) extending from the vane (S) contacts the pole face of electromagnets (H) which, when activated, serves to inhibit movement of the vane irrespective of activation of the row electromagnet (D).  Thus by pulsing the display row-by-row, the state of the display elements can be set by selective inhibiting of movement in coincident manner of the appropriate vanes (S) by pulsing the respective column conductors.

Abstract: A SEALED VALVE     ABSTRACT        The invention has especial utility for providing com-pletely safe hermetic sealing of actuators extending into highly sensitive or isolative process equipment, such as that using atomic radiation. The invention uses a gen-eral principle taught by the inventor's prior U.S. Pat. No. 3,933,052. The actuator is hermetically sealed by the aid of a flexible diaphragm, and the diaphragm is made safe by pressure compensation. A sealing liquid confined on the outside of the hermetic diaphragm ap-plies the same pressure to the outside face of the dia-phragm as is applied by the process atmosphere to the inside face of the diaphragm. According to the embodi-ment illustrated in that patent, a diaphragm (actually a bellows) entirely separate from the actuator was ex-posed to the process atmosphere to apply its pressure to the sealing liquid. According to the present invention, a diaphragm which accommodates the movement of the actuator and accomplishes the hermetic sealing also transmits the pressure of the process atmosphere to the sealing liquid. The present invention also has some fea-tures of "fail-safe" nature and achieves other simplifica-tion. Also, it provides a temporary seal that permits servicing of the outer packing around the actuator.
