Abstract: ABSTRACT         An improved method and apparatus for quenching elongated steel pipe in a liquid cooling medium, substantially improves the straightness of the finished product.  After being heated to an initial temperature higher than the austentite transformation temperature, the pipe is positioned within an array of spaced restraining elements defining an unobstructed cylindrical space dimensioned to receive the pipe without substantial clearance while leaving the exterior surface of the pipe substantially unobstructed.  Two streams of coolant are introduced to flow through the interior of the pipe, and over the exterior of the pipe, respectively, the relative volumes of flow of the two streams of coolant being regulated, to ensure substantially uniform rates of cooling as between the interior and exterior surfaces of the pipe.  In some embodiments, the apparatus includes an enclosure, at least as long as the pipe to be quenched, which surrounds the cylindrical space within which the pipe is confined during quenching, the external stream of coolant flowing through the annular space between this enclosure and the pipe.  The method may be practiced in a existing inside-outside quench unit, through the use of conversion apparatus comprising means for forming an array of spaced restraining elements inside the existing quench tank, to receive a pipe for quenching.  Such conversion apparatus may also comprise means for forming an enclosure, to surround the pipe during quenching in the tank.

Abstract: METHOD FOR THE PRODUCTION OF FIBER PULP     ABSTRACT OF THE DISCLOSURE        This invention relates to a method for the produc-tion of fiber pulp from lignocellulosic material contain-ing at least 70% spruce or spruce-like material.  The method comprises the steps of lignin softening and de-fibration/refining, the step of lignin softening being performed prior to the step of defibration/refining and comprising impregnating the starting material with a dilute aqueous solution of a lignin softening agent, namely a solution of sulfurous acid, metal bisulfite salts and/or metal sulfite sales in an amount sufficient to provide a defibrated/refined pulp containing an ab-sorbed and bonded amount of sulfonate groups within the range of from 0.06 to 0.75 wt.-%, calculated as Na2SO3 and based on the dry pulp weight. The absorbed and bonded amount of sulfonate groups is balanced to the composition of the starting material and the tempe-rature-pressure conditions in the defibration step to provide a pulp of maximum tensile strength such as to represent a point within the polygon ABGH in Fig. 1.    The invention makes it possible to utilize favorable effects, not earlier known, resulting from very low concentrations of the lignin softening agent, and to produce a pulp with high yield and optimum strength and optical properties at a comparatively low energy input in the defibrator/refiner.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus is provided for welding studs to a workpiece with the area around the welds being substantially free of smut. The existence of the smut detracts from the appearance of the workpiece and if the workpiece is to be painted or otherwise covered with a coating material, the smut must first be removed. The coating of smut can be eliminated if, during the weld pro-cess, fluid is carefully deposited on the weld area around the end of the stud where the weld occurs.  The fluid consists of a small volume of low-pressure air and an anti-smut liquid.  The latter also helps to keep weld splatter from adhering to the in-terior of a spark shield used with the stud.  However, by apply-ing a non-metallic, preferably plastic, sleeve within the spark shield, the problem of splatter can be further reduced or sub-stantially eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method of minimizing slag carryover when draining molten metal from a furnace.  A polyhedral-shaped body having density intermediate that of the slag and metal is thrown onto the surface of the slag within a restricted area over the furnace taphole.  The body will float at the slag-metal interface, and tend to lodge with one of its corners projecting into the taphole as the final portion of remaining metal drains out of the furnace.          The shape of the body and its dimensions are selected so as to only partially block the taphole opening, causing flaring of the stream so as to signal a furnace operator of the impending flow of slag from the furnace.  The operator then shuts off flow to prevent carryover of slag onto the molten metal already tapped,  Since only the edges of the body contact the taphole, of the body does not become welded to the wall of the taphole and therefore is easily dislodged without loss of time between heats.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a method and apparatus for centrifugally separating substances of diff-erent atomic weights.  The substances to be separated are positioned in an evacuated vessel which has a longitudinal axis.  A magnetic field is generated in the vessel parallel to the longitudinal axis of the vessel and a target com-prises of the substances to be separated is positioned within the vessel at one end thereof.  A collector is pos-itioned at the other end of the vessel. Pulsed laser energy is focused on the substances to be separated, thereby fully ionizing at least a portion of the substances and forming a plasma therefrom.  Immediately following the focusing of the laser energy, a current is passed through the substances to be separated which causes further full ionization of the substances and thereby the formation of additional plasma.          The ionized plasma is rotated and moved from the substances which are to be separated to a collector by the application of the magnetic field.  At least a portion of the ionized substances are separated by the centrifugal force result-ing from the rotation of the plasma by the magnetic field.          At least one skimmer means is positioned in the vessel in the path of a portion of the ionized plasma such that the portion of the ionized plasma strikes the skimmer means and is collected thereon.  The remainder of the ionized plasma continues moving along the vessel towards the collector.

Abstract: ABSTRACT OF THE INVENTION            A liquid crystal display produces a still image derived from a video signal by use of a comparator and selected reference levels to derive the driving signal for the liquid crystal display array.  The vertical and horizontal samples and timing pulses derived from the original video signal of the image to be displayed are stored in shift registers, respectively and then read out into multiplexes for feeding to the liquid crystal display array.  The multiplexers are analog gates that have connected thereto in addition to the shift register output signal a plurality of voltages derived from a voltage divider network that sets the level of the voltage applied across each liquid crystal device in the array.  No analog-to-digital converter or multiple shift register and specialized switch combination are required and thus the operational margin or sensitivity of the liquid crystal display is not adversely affected and the driving circuit is relatively uncomplicated.
