Abstract: CERAMIC FILTER AND METHOD FOR USING SAME                Abstract of the Disclosure A ceramic filter for filtering molten iron is dis-closed.  The ceramic filter is made from a high-melting ceramic material having an open-celled foam structure, a variable bulk density in different portions of the filter, and at least one afflux surface.  In order to filter molten iron efficiently, the ratio of filter surface to filter volume should be in the range of about 0.0003 to 9 m2/cm3, the spe-cific filter resistance should be in the range of about 0.01 to 0.9 bar-cm at a flow rate of 5 m3/hour, and the pres-sure loss .DELTA. p across the filter should depend on the specific resistance? , the filter length, and the surface area of the afflux plane F in accordance with the relationship:          .DELTA.p??x ?.   A method for filtering molten iron using this ceramic filter is also disclosed. In this method, the ceramic filter is located near the point in the casting system where the molten iron has its greatest kinetic energy.  The  molten iron is first caused to flow tangentially by the afflux plane of the ceramic filter and then is deflected to create turbulence directly before the afflux plane of the filter.

Abstract: ABSTRACT OF THE DISCLOSURE              A circuit arrangement four conference circuits in digital communications systems, particularly in PCM telephone systems, provide digitized voice signals of the conference participants which are added in the conference circuit and are transmitted to all conference participants minus a voice signal generated by the respective participant.  In the conference circuit, linear samples are transmitted to a subtracter in a frame-delayed manner by an intermediate memory and are compared by a transverse filter to the sum of all preceding samples respectively multiplied by a correction value derived dependent on the phase position to the sum of a momentary sample.  As a result, each conference subscriber receives the sum of the voice signal of all conference subscribers minus his own voice signal, whereby the echo signals of the conference participants are suppressed except for one's own echo signal.

Abstract: Video Display Control Circuit Arrangement Abstract of the Disclosure The present circuit arrangement is principally directed to scrolling of a region or regions on a video display and includes a bit map memory, at least one address generation and control signal circuitry chip, one or more data signal path circuitry chips, timing circuitry and logic circuitry interconnecting the foregoing various sections of circuitry.  The present arrangement functions to refresh, scroll and update during each horizontal scan, in response to a plurality of timing cycles, with every other cycle being a refresh cycle and the intervening cycles being either scroll or update cycles.  During a refresh cycle there is a burst of signals read from memory and transmitted to a shift register feeding the video screen to effect refreshing a section of the screen. During the alternate cycles (between refresh cycles) there may be a burst of signals from the signal path circuitry chip to write information into the bit map memory at some new address to effect scrolling.  Instead of performing scrolling in the alternate cycles, information may be erased from a region.  In the alternative there may be a burst of signals from an information source transmitted to the bit map memory to effect updating (i.e. writing new data information into the memory).  The foregoing arrangement permits the entire bit map memory to be rewritten during the period required for one vertical scan of the video display device, which in turn enables the system to provide rapid smooth scrolling and continued sequential addressing of the memory.

Abstract: ABSTRACT  .        The permeability of higher permeability zones of a subterranean reservoir of heterogeneous permeability is reduced by injecting (1) an aqueous solution of A crosslinkable water-soluble polymer, a material capable under certain conditions of at least partially crosslinking the polymer to form a gelatinous precipitate, a water-soluble alkaline material in an amount sufficient to maintain the pH of the aqueous solution above the pH at which crosslinking occurs until the composition has passed a desired distance through the reservoir, and a water-soluble surface active agent; and (2) a gas mixture comprising an acid gas.  A gelatinous foam forms in situ useful for blocking escape of fluids both gaseous and liquid, into the higher permeability zones of the reservoir during enhanced recovery, typically by carbon dioxide flooding.  The polymer-surfactant solution and the gas mixture can be injected in alternating slugs to enhance formation of the gelatinous foam and to allow for plugging of higher permeability zones progres-sively encountered during recovery operations.     .
