Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a filter press in which between a pair of heads a plurality of filter plates are connected to one another by loose connecting means.  In the improved apparatus, the heads are both movable so that the filter plates may be moved in sequence, simultaneously from both end sides, toward the center to close the intervals there-between or away from the center to provide intervals there-between, whereby the time required in assembling and separating the filter plates can be considerably reduced.  When the filter plates in assembled state, if one of the heads is pressed, while the other head is placed under action of stoppers, the filter plates are vigorously tightened by a cylinder having a shorter stroke than that in the prior-art apparatus.

Abstract: Abstract Molten aluminum, magnesium, or their alloys, or other metal is solidified in a mold or casting device from which an ingot is continuously and progressively withdrawn.          The ingot as initially formed has a solid shell and a liquid core which progressively solidifies as the ingot is withdrawn through and from the casting device.  As the ingot emerges from the casting device it is contacted directly with water or other coolant referred to as direct chill.          Improved casting rates can be achieved without cracking the ingot where the direct chill cooling effects are divided into three successive zones.  In the first direct chill zone a relatively high chill rate is employed, after which a retarded chill rate is employed in a second direct chill zone followed by a higher chill rate in a third direct chill zone.  Thus, the ingot is drawn through a high direct chill rate zone then a lower direct chill rate zone and then a higher direct chill rate zone.  The intermediate low chill rate zone is effected preferably by use of a dissolved gas such as carbon dioxide, which establishes a heat insulating film or layer around the solidifying ingot to retard heat extraction.  At a predetermined distance from the mold that film is then mechanically disturbed as by a comb, rake or other mechanical action or as by a jet of water, air or other fluid to establish a higher chill rate for the third zone.

Abstract: S P E C I F I C A T I O N               Title: METHOD AND SYSTEM FOR WELL        VELOCITY SHOOTING AND VERTICAL SEISMIC PROFILING          Inventor:  PAUL CHELMINSKI             ABSTRACT OF THE DISCLOSURE         Method and system are provided for well velocity shooting and vertical seismic profiling utilizing mobile seismic land sources for transmitting powerful seismic energy impulses into the earth.  A plurality of nesting pairs of tanks are transported on a single vehicle to a well site where the tanks are unloaded and arranged in a suitable array, for example, in a linear array or uniformly spaced around the mouth of the well.          The tanks or containers each have a displaceable end portion serving as a diaphragm which is placed in contact with the ground near the well, and then the tanks are filled with a noncompressible liquid, usually water, at the well site.  The total effective mass of the liquid may be increased by adding density-increasing materials thereto for example "drilling mud".       Air guns are suspended in the tanks submerged in the liquid there in.  The air guns are fired in a predetermined manner, abruptly releasing pressurized gas into the liquid contained in the tanks for providing powerful seismic impulses, i.e. vibrational waves, which are transmitted into the ground by the displaceable diaphragms.  Geophone equipment which has been lowered into the well receives the resultant waves after they have passed through the geological structures near the well and have been reflected and/or refracted or otherwise affected by such structures,and the signals from the geophone equipment may be recorded for later analysis and/or processed at ground level, with the objective to determine the earth structures and possible oil or gas bearing regions near the well.  Advantageously, a mobile system is provided in which a single vehicle can provide an array of four seismic sources positioned near the mouth of a well instead of requiring four vehicles by virtue of providing nesting pairs of tanks which can be set up at the well site with airguns fired therein, thus providing a very effective and convenient method of obtaining powerful seismic signals for deep penetration into the earth.  Moreover, nesting trios or a larger multiplicity of nesting containers can advantageously be provided for greatly increasing the vehicle capacity in terms of seismic sources per vehicle.
