Abstract: SOLVENT PULPING PROCESS          ABSTRACT OF THE DISCLOSURE           Solvent pulping of wood chips or other fibrous plant material is effected using an aqueous solution of a lower aliphatic alcohol in a plurality of batch extraction vessels.  The charge in each vessel is heated rapidly to pulping temperature by recirculation of a primary extraction liquor having a relatively high dissolved solids content, and thereafter the charge is subjected to a series of once-through extractions or washes with successively cleaner liquors, including a final extraction or wash with fresh liquor.  The extraction liquor from one extraction stage in one vessel is used in another extraction stage in another vessel.  Upon completion of the extraction, the liquor is drained from the vessel, the vessel is depressurized to a solvent condenser, and the remaining solvent is steam stripped from the charge and recovered.  The used extraction liquor is treated in an alcohol recovery system by flash vaporization, condensation of the solvent vapors, and vacuum stripping of the residual liquor with steam.  The alcohol-free extract is then treated to recover a concentrated aqueous lignin suspension and a concentrated aqueous carbo-hydrate solution.

Abstract: ABSTRACT            A flexible shaft coupling wherein the flange of at least one of the shafts is flexible and its marginal portion is separably fastened to the marginal portion of the other flange.  The flanges surround thrust transmitting elements which are urged against each other as a result of deformation of the flexible flange in response to fastening to the other flange.  The flexible flange may be in-tegral with or it may be separably fastened to the shank of the re-spective shaft.  The flexibility of the coupling is enhanced if the flexible flange is provided with or mounted between knife edges which permit such flange to snap over in response to tilting of one shaft with respect to the other shaft and/or vice versa.  The thrust transmitting elements may be integral with the respective shafts or they may constitute removable inserts.  One of the thrust transmit-ting elements has a convex face which bears against a flat face of the other element so that the elements are in mere point contact with each other.  The plane of the point of contact may but need not coincide with the plane where the marginal portions of the flanges abut against each other.

Abstract: ABSTRACT OF THE DISCLOSURE A jig for longitudinally cutting timber with a chain saw comprising a pair of parallel rails extending longitudinally and supported on a rack. A plate between the rails supports the chain saw thereon.  The plate has a slot parallel to the rails through which the blade and chain saw extend during operation   The plate is secured to a wheeled carriage means which operates along the rails.  A handle of the chain saw is clamped above,  and the blade of the chain saw is clamped below, the plate to secure the chain saw in position during the sawing operation.  Timber to be cut is secured beneath the plate parallel to the rails and is cut by moving the carriage means longitudinally along the rails, causing the chain saw to cut the timber longitudinally.  The plate is laterally adjustable between the rails to permit a series of parallel longitudinal cuts to be made in the timber so that, for example, lumber of appropriate thickness may be obtained.  This jig is readily constructed and taken apart and is well suited for use with a chain saw as a portable saw mill for domestic or remote operation.
