Abstract: COAL LIQUEFACTION PROCESS UTILIZING SELECTIVE HEAT ADDITION          ABSTRACT OF THE DISCLOSURE           A process for liquefying coal involving heating only a portion (70) of the total process hydrogen stream (62) to increase its temperature to a relatively high level and admixing said heated hydrogen with only a portion (56) of the total coal slurry (54) in the up-stream region of a dissolver zone (58).  The hydrogen stream has a relatively low specific heat and the addition thereto of a relatively small amount of heat increases its temperature to a level which is sufficiently high to initiate hydrocracking reactions when the hot hydrogen stream is intermixed with only a portion (56) of the dissolver feed slurry, provided that the dissolver feed slurry contains recycle mineral residue in an amount adequate to catalyze hydrocracking reactions.  Because the recycle mineral residue catalyzes the exothermic hydrocracking reactions, sufficient process heat is generated to permit addition to the dissolver zone (58) in a downstream region thereof the remainder (60) of dissolver feed slurry and process hydrogen (74) in a relatively cool condition.

Abstract: RAIL HOUSE CAR DOOR CRANK MOUNT     Abstract of the Disclosure A rail house car with at least one opening along each of its sides.  The car includes a door for closing each of the openings by movement of the doors longitudinally along the car sides and laterally into and out of the openings.  Bottom and top rotating crank members moveably support and retain the doors on longitudinal tracks below the doors and within longitudinal retainer means above the doors.  At least some of the crank members are selectively manually driven by rotational means for selective lateral movement of the doors.  The top crank members adjacent the upper portion of the doors each include a bore.  A forged pin is telescopingly received in each of a plurality of pipes rotationally mounted on the door,  Each pin has a shank portion and an upper headed or flanged portion.  Each crank member's bore is counterbored to receive the headed portion of a pin.  Substantially the entire periphery of the shank portion is welded to its associated crank member and only a portion of the flange formed by the head of the pin is welded to the crank member counterbore.  This minimizes deterioration of the strength given to the pin flange by the forging operation.  Alternatively, the head can be spaced from the top of the crank member and only the shank portion welded to it.  The crank mount is also for use with any auxiliary crank members which are in engagement with the longitudinal retaining means of the car.  A pin or weld or both can secure the extension pin and pipe to prevent relative rotation therebetween.

Abstract: SINGLE ELECTRODE U-MOSFET              RANDOM ACCESS MEMORY                     Abstract A method for making highly dense, dielectrically isolated, U-shaped MOSFET.  In a preferred method a monocrystalline silicon P substrate with a N+ layer thereon, a P layer on the N+ layer and a N+ layer on the P layer is provided.  A pattern of U-shaped openings is formed in the body through to the P substrate by the reactively ion etching technique. This pattern of openings is filled with an insulator material, such as silicon dioxide.  A conductive layer of N+ doped polycrystalline silicon is deposited on the bare surface of this silicon body. Openings are formed in the polycrystalline silicon over the silicon dioxide filled openings.  A silicon dioxide layer is then grown by, for example, thermal oxidation over the polycrystalline silicon layer. Reactively ion etching is used to produce substantially U-shaped openings through the layers over the P substrate and into the P substrate to substantially bisect the regions of monocrystalline silicon. This etching step forms two storage cells in the monocrystalline silicon areas and a bit line for each column of cells in the polycrystalline silicon layer.  A silicon dioxide gate insulator is grown on the monocrystalline silicon surfaces of the U-shaped openings by thermal oxidation in a suitable ambient.  Conductively doped polycrystalline silicon is deposited in the U-shaped openings over the silicon dioxide gate insulator layer until the openings are filled and cover the surface of the body.  The conductively doped polycrystalline silicon on the surface of the body is etched in a suitable pattern to produce the word lines of the random access memory device.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved valve-gated injection molding system.  The hot runner passage through which the melt flows to the cavity is divided into three spiral-shaped channels which converge again immediately before the gate, thereby imparting a curving motion to the melt as it flows outward from the gate in the cavity.  This avoids unidirectional molecular orientation of the melt, thereby providing a stronger molded product.  In a preferred embodiment of the invention, the melt channels reduce in helical diameter and cross sectional area as they approach the gate, thereby accelerating the swirling motion of the melt.

Abstract: Abstract of the Disclosure An inner frame having upper and lower portions carries an inkable pad in the lower portion thereof.  The inked die projects below the inner frame for contact with a surface to be stamped.  An integral retaining ridge is located on the outer surface of the inner frame between the upper and lower portions.  An outer frame is detach-ably connected to the inner frame and a hollow sleeve member is interposed between the inner and outer frames.          The sleeve member has an upper flange which is located above the integral retaining ridge.  A plurality of C-shaped resilient fingers integrally molded with the inner frame, outer frame or the sleeve member is located be-tween the upper flange of the sleeve member and the inner and outer frames.  The lower edge of the sleeve extends below the level of the inkable pad when the spring member is in the relaxed position.  Downward pressure on the outer frame is transmitted by the detachable connection to the inner frame.  The result is that the inkable pad contacts a surface to be stamped and the sleeve member telescopes into the inner and outer frames, compressing the C-shaped resilient fingers.  Each end of the resil-ient fingers has a projection with a tapered upper sur-face and an engaging lower surface facilitating assembly of the structure wherein the sleeve member is slipped over the inner frame so that the flange is located between the projection and the retaining ridge.

Abstract: A device for flushing and aerating a surface coated with microorganisms in a plant for biological purification of waste water.            A B S T R A C T            A rotary system composed of two worms which are built together and interconnected at their central coils, said worms having their respective coils oppositely directed to one another and consisting of spirally coiled pipes, is used for flushing and aerating a medium which is disposed in the pipes and coated with micro-organisms. The microorganisms take up nutrients from waste water in a biological purification process, one worm with part of its periphery immersed in the water lifting quantities of water towards its centre, the other worm lowering the water to the original level. This provides for alternate flushing and aeration, and the weight of the water in said second worm provides a torque which contributes towards driving the system.
