Abstract: Abstract A method of underground gasification of a coal seam comprises the steps of opening it by drilling injection a and production wells, interconnecting said wells, setting the coal afire and gasifying the coal by supplying a gase-ous medium into the first wells and removing the produced gas from the second wells. The seam is gasified successi-vely layer in the direction from the roof of the seam to its bottom. Each subsequent layer is gasified after gasifi-cation of the preceding layer is completed and rock over-lying the gasified layer is no longer shifted. The thickness of said layer is chosen so that the height of a zone containing cracks formed as a result of rock shift does not exceed the depth of occurrence of the gasified layer.

Abstract: HYDROGENATION OF UNDISSOLVED COAL AND SUBSEQUENT          LIQUEFACTION OF HYDROGENATED COAL                   ABSTRACT OF DISCLOSURE        A staged process for hydrogenation of undissolved coal and subsequent liquefaction of the hydrogenated coal to provide useful hydrocarbon liquid products including naphtha, gasoline and diesel fuels.  These low boiling hydrocarbon liquids are produced by the process comprising: (a)  mixing solid coal particles with a hydrocarbon solvent oil in a solvent/coal ratio ranging from about 8/1 to about 1.5/1 to provide a flowable coal/oil slurry; (b) passing said coal/oil slurry and hydrogen upwardly through a first stage reaction zone containing a coal-derived liquid in a catalytic bed of particulate; catalyst maintained at a temperature ranging from about 400° to about 700°F and a hydrogen partial pressure of 100 to 2000 psig for a residence time sufficient to hydrogenate the solid coal particles;  and (c)  withdrawing the coal/oil slurry con-taining the hydrogenated coal particles from the first reaction zone and passing the coal/oil slurry to a second stage reaction zone containing a catalytic bed maintained at a temperature of between about 700° and about 850°F and a hydrogen partial pressure of 100 to 2000 psig to liquefy and convert the coal to useful hydrocarbon liquid fuel products.  The first and second stage reaction zones may contain the same or different catalysts such as Co/Mo on a porous substrate such as alumina or silica.  The process preferably uses a coal-derived slurrying oil and first stage temperature of 550-650°F. and second stage temperature of 800-825°F.

Abstract: ABSTRACT OF THE DISCLOSURE  Process for the determination of the interfacial area in a container containing a two-phase mixture incorporating a liquid phase and a gaseous phase flowing in the liquid phase in the form of bubbles.         For a same path of a sequence of ultra-sonic sound wave trains emitted at constant amplitudes in said container, the ratio of the mean values of the maximum amplitudes of the wave trains received after passing through the two-phase mixture and after passing through the liquid phase only is determined and the thus determined ratio is plotted on a calibration curve giving the interfacial area value as a function of this ratio.

Abstract: ABSTRACT     A method and apparatus for delivering an explosive to the bottom of a borehole containing water without allowing a detrimental amount of mixing between the explosive and the water.  More particularly, the present invention allows an ammonium nitrate  rich bulk explosive  to  be placed  in a borehole  without  allowing  the  explosive  composition  to change   significantly   through   dissolution   of    its constituents   The  apparatus  of  the  present  invention includes a length of collapsible tubing having a plurality of apertures near its base and a weight attached to its its base.  The tubing  is  then  lowered  into  a borehole.  The weight causes the tubing to extend through any water layer within the borehole and the collapsible nature of the tubing serves to keep any significant amount of water from entering the tube.  An explosive can then be flowed into the mouth of the tubing and down through the length of the tubing to the bottom of the borehole.  At the bottom of the borehole, the explosive  exits  the  tubing  through  the  plurality  of apertures.

Abstract: FILTERED LECITHIN IN FATS                             Abstract Cooking fat compositions containing pretreated lecithin which resist thermal darkening are disclosed. The pretreatment, which comprises the addition of water to lecithin dissolved in a minimal amount of fat followed by heating and filtration, results in a decrease in the thermal discoloration of lecithin with no substantial reduction in its anti-sticking properties. This enables the use of lecithin at levels in fats higher than for untreated lecithin to improve the anti-sticking performance of the fat.

Abstract: ABSTRACT OF THE DISCLOSURE A vehicle wheel, especially for a truck.  The wheel has a rigid rim on which can be mounted a pneumatic tire of rubber or rubber-like material. The carcass of the tire is anchored in the tire beads by being looped around pull-resistant bead cores.  The tire beads are disposed on the radially inner periphery of the rim ring.  In order to make it particularly easy to mount the tire, the rim seating surfaces for each tire bead extend essentially horizontally in the transverse direction, and extend to the edge of the rim ring.  A clamping ring is disposed radially inwardly of the tire bead, with that side of the clamping ring which rests against the bead extending at an angle to the axis of rotation of the wheel.  The bead core has a cross-sectional shape which includes sides which extend essentially parallel to the clamping ring and parallel to the rim seating surface.

Abstract: ABSTRACT     Improved apparatus for reducing, to a smaller size, residue or debris left behind after a tree processing or har-vesting operation.  The apparatus includes a first reduction unit which includes a plurality of cutter knives radiating outwardly from a hub at positions spaced circumferentially therearound and longitudinally therealong and cooperate with fixed knives to reduce the residue to smaller size.  Down-stream there is located a second reduction unit (a common hammer mill) and downstream therefrom a fan unit for deliver-ing the reduced sized particles to a collecting container or other area.  The units preferably are vertically oriented i.e. stacked one on top of the other resulting in self-feeding from one unit to the unit therebelow. If desired an impeller infeed means can be utilized for infeeding the material to the cutters of the first stage reduction unit.  The apparatus may be permanently mounted at a suitable location or alternatively mounted upon a self-propelled mobile vehicle movable from one location to another and towing a trailer having a chip collect-ing or debris collecting container mounted thereon.  To over-come clogging problems the cutter knives of the first stage unit have baffles mounted thereon extending in a direction parallel to the axis of rotation of the cutter knives.  These baffles or impeller blades facilitate the flow of debris through the apparatus.  Another embodiment to reduce clogging involves having the fan blades cutback at their attachment to a hub which is mounted for rotation to facilitate infeed of material to the fan unit.  The cutback of the blades effective-ly provides an open generally conical infeed path along a por-tion of the depth of the blades about the axis of rotation thereof.  The two different embodiments can be used individual-ly or in combination.

Abstract: ABSTRACT A position responsive switch apparatus comprising a housing and a mounting assembly secured within the housing.  The mounting assembly includes a pair of oppositely disposed spaced-apart walls.  Each of the walls has an aperture contained therein which are in general axial alignment.  An elongate switch extends through the apertures and is transversely supported by the mounting assembly so that the switch may move in a generally longitudinally axial direction within the confines of the mounting assembly.  The switch may be in one of two preselected conditions.  The switch moves from one condition to the other condition in response to an opposing directional displacement of the switch.  A retaining element is carried on the switch intermediate of the apertures.  The retaining element is of a greater dimension than the apertures so that the walls moveably retain the switch within the mounting assembly.
