Abstract: ABSTRACT OF DISCLOSURE:           A roller reamer for boring holes in the earth is useful for both well drilling and in mining.  The reamer rollers are replaceably mounted on the reamer body in a manner that facilitates easy replacement so that the body can be reused after its initial comple-ment of rollers is worn out.  To that end, the rollers are rotatably mounted on shafts whose ends are support-ed by blocks inserted in the reamer body.  To prevent shaft rotation, one end of each shaft is welded, pinned, or otherwise nonrotatably anchored to its mounting block. Each block makes an interference fit with the body socket in which it is disposed.  The blocks are stepped for quick release;  Access openings to the backs of the blocks facilitates knockout.  Knockout of the stepped blocks is achieved by wedge means.           Drilling mud may have access to contacting surfaces of rollers and shafts to lubricate same. Protective seal means may be provided between each roller and shaft at the upper ends thereof so that the mud must flow upwardly to reach the space between shaft and roller and dense solids will be excluded by gravity. Grease lubrication may be provided, the rollers being sealed to the shafts at both ends.           With mud lubrication, axial loads on the rollers may be taken by the ends of the rollers bearing on the blocks.  With protected mud lubrication and grease lubrication, thrust may be taken by thrust bearing surfaces provided within the protected or sealed zone, e.g. by a flange on each shaft engaging an internal groove formed by a two piece roller, or a ball lock between opposed annular grooves in shaft and roller.

Abstract: Abstract of the Disclosure An improved method of casting an article includes using the same starter element during the casting of a plurality of metal articles.  In one specific instance the starter element consisted of a single metal crystal.  The single crystal starter element was used to initiate the solidification of molten metal in a mold to form a single crystal cast article.  This was done without significant bonding between the solidified metal and the single crystal starter element.  Therefore, the starter element could be separated from the solidified body of metal and subsequently used in the casting of another article.  In order to tend to maximize the rate of heat transfer from the starter element and to tend to minimize bonding of the molten metal with the starter element, the starter element is advantageously located in a recess In a chill block with an upper surface of the starter element even with an upper surface of the chill block.  In order to retard formation of condensation and to prevent eroding of the metal of the starter element, one or more layers of metallic foil may be disposed between the starter element and the mold cavity.

Abstract: Abstract of the Disclosure Fibrous mat type burner can have mat pieced together with butt joints and very thin layer of resinous sealant uniting the pieces at the joint. Burners with elongated mats are thus readily manufactured, and can be packaged strapped together in pairs face-to-face and enclosed in telescoping carton halves that allow for packaging burners of different lengths.  Simple cushion-ing strips such as of folded corrugated cardboard can be inserted between burner faces, and cushioning pads over outer edges of burner backs, before they are strapped together.  Holes can be provided in the cushioning strips to hold them in place over fastener heads projecting from burner face.  Burners with hat-shaped mats for enveloping and brazing heat-exchange tubes to tube sheet can be used individually or in pairs to effect such brazing on tube-and-sheet assemblies secured on rotating table and indexed into position under burners.  Suction ring around bottom of burner draws off some hot combustion gases generated in burner. Lowering and raising of burner over top of tube-and-sheet assembly, as well as of suction head against bottom of tube-and-sheet assembly is conveniently effec-ted using large-diameter suction piping with loose joints that allow pipe rotation to accommodate such movement.  The tubes can be staked or expanded where they penetrate the tube sheet, to reduce the clearance between them.

Abstract: ABSTRACT OF THE DISCLOSURE:         A process of recovering oil from oil-containing minerals by retorting on a traveling grate, wherein a bed is charged, which consists essentially of a layer of oil-containing mineral and a layer of retorted and burnt material, which has been left after solid carbon present in the bed after the retorting has been burnt with ignition and a flow of oxygen-containing gases sucked through. Gases are heated in the retorting zone to the temperature required for retorting as they pass through the layer of the burnt mineral.  The layer of oil-containing mineral is heated to the retorting temperature by the heated-up gases as they flow through said layer, and oil is separated in a separating stage from the retort gases which contain the retorting products.  Hot burnt material which becomes available after the combustion of solid carbon is charged onto the traveling grate to form a bottom layer and oil-containing mineral is charged onto the layer to form a top layer.  Inert or reducing gases are forced through the charge bed from below in the retorting zone and are heated as they flow through the hot bottom layer and effect retorting as they pass through the top layer.  The retort gases leaving the retorting zone are passed through the separating stage to remove the oil from said gases.  The solid carbon in the surface of the top layer is ignited by means of an ignition furnace in a combustion zone, which succeeds the retorting zone.  The burning zone is thereafter caused to move through the top layer from below as oxygen-containing gases are sucked through the top layer, and burnt material is removed from the bed discharged from the traveling grate and is recycled hot to form the bottom layer.

Abstract: ABSTRACT OF THE INVENTION      The invention relates to a device for preventing length measuring errors resulting from accidentally remaining local offshoots from a portion of the butt end of a tree stem which is continuously advanced toward a cross-cutting member for cutting the stem in predetermined length sections.   A stem-measuring device periodically emits a cutting impluse to the cross-cutting member so that the advancing stem will be cut into predtermined lengths.   Two detectors are provided in a spaced relationship for sensing the entering of the butt end into a detecting station and then emitting an actuating signal to start the measuring device.   The spacing of the two detectors, which are symmetrically positioned with respect to the centerline  of the stem path, does not exceed a pre-determined minimum butt diameter.   The measuring device is not actuated until signals from both detectors are emitted.   Thus, sensing of a local offshoot from the butt end by only one of the detectors does not start the measuring device with the result that the offshoot does not cause a shorter-than-desired length of stem.
