Abstract: ABSTRACT OF THE DISCLOSURE         A method for reducing zirconium is disclosed in which a reductant metal, preferably aluminum, is dissolved in the molten state in a solvent metal, preferably zinc.  This molten metal phase is contacted with a fused salt phase which includes a zirconium salt to be reduced as one of its components.  The desired reduction is effected by mutual dis-placement, with aluminum being transported from the molten metal phase to the fused salt phase, replacing zirconium in the salt, while zirconium is transported from the fused salt phase to the molten metal phase.  The fused salt phase and the molten metal phase are then separated, and the solvent metal and zirconium are separated, such as by distillation.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a method of extruding from uncured debarked or unpeeled logs a plurality of wood strips which can be subsequently pressed and glued together to form a laminated wood product.  The method of extruding the uncured unpeeled logs into a plurality of wood strips comprises extruding an uncured log in a direction along the grain of the log through a parallelogram -shaped and preferably rectangular grid of intersecting cutting blades which form a series of correspondingly parallelogram-shaped apertures at a pressure sufficient to force the uncured log  through the apertures, thereby extruding the log into a plurality of wood strips of generally parallelogram-shaped cross section.  The apparatus for extruding the logs into a plurality of wood strips comprises an elongated frame, an end plate positioned at one end of the elongated frame, at least one hydraulic ram which is located at the end of the frame opposite the end plate and extends parallel with the elongated frame in the direction of the end plate, and a parallelogram-shaped grid of intersecting cutting blades secured to the end of the hydraulic ram that extends in the direction of the end plate.

Abstract: Abstract A hose clamp body is provided for use with a pair of bolts each having a shank and a head.  A surface on the body grips the hose and a first opening generally transverse to a first surface on the body receives the shank of one of the bolts.  The head of this one of the bolts is provided with a flat side surface laterally spaced a predetermined distance from the diametrically opposite side of the shank.          Provided on the body is a second surface which intersects the first surface and extends away therefrom to an upper edge to form an acute angle relative to the longitudinal axis of the opening.  The predetermined distance is less than the transverse distance between the upper edge and the diamet-rically opposite side of the first opening and greater than the transverse distance between the intersection and the diametrically opposite side of the first opening so that the flat side of the head of the above-mentioned one of the bolts engages the body second surface before this bolt head contacts the first surface to prevent this bolt from turning relative to the body.  The body also has a second opening on the other side of the gripping surface to receive the other of the bolts, the body having a third surface generally transverse of this second opening and a fourth surface intersecting the third surface and extending therefrom, and this fourth surface being slanted at an angle of greater than 45° relative to the longitudinal axis of the second opening.

Abstract: ABSTRACT OF THE DISCLOSURE      A material handling vehicle is provided with an articulating and an oscillating hitch assembly between a tractor portion and a trailer portion thereof. The hitch assembly telescopes a pinion gear support or trunnion housing carried by a differential gear housing into an oscillation housing. The oscillation housing is pivotally connected to the tractor and permits the tractor to pivot about a generally vertical axis and to oscillate about a longitudinal axis of the housing, both oscillation and pivoting being relative to the trailer as the vehicle is propelled over a terrain. The telescoping of the pinion gear or trunnion housing and oscillation housing makes it possible to eliminate parts and affectively shorten the length of the vehicle without sacrificing any flexibility or strength in  the hitch assembly between the tractor and the trailer.

Abstract: ABSTRACT         An expansion joint with an elastomer seal having longitudinal frames made from aluminum extrusions extending longitudinally of an expansion joint for pavements and bridge decks.  The longitudinal frames are mounted by anchor bolts in the pavement or bridge deck concrete, which pavement or bridge deck has a concrete or asphaltic wear surface.  The elastomer seal is fixedly held in the longitudinal  frames by elongated tongue and groove means, and the joint space is spanned by at least one shallow, V-shaped elastomer wall which deforms downwardly as the Joint width become narrower.  The longitudinal frames are held in position in steps in the concrete adjacent to the joint by the anchor bolts, at least some of which have threaded ends projecting upwardly through the bottom wall into an upwardly facing longitudinal channel.          The joint-remote outer face of the end wall of the frames has a slight transverse taper from its top edge to its bottom edge to facilitate release of the frames from abutting pavement when removing the frames from the steps.

Abstract: ABSTRACT OF THE DISCLOSURE     In overhead cranes of the kind including a box girder fabricated of elongate plates and torsionally loaded by a trolley running on three rails respectively at three corners of the box girder, the structure of the box girder is usually such that flanges project from the corners thereof and prevent proper support of the rails in optimim corner positions in alignment with the walls of the girder.  This problem is now solved by providing a rail with an elongate flange and securing the rail and flange respectively to marginal portions of a pair of adjacent plates of the box girder.  In this way the rail can be secured in optimum position at the corner of the girder and forms with the flange a member which encloses the corner flange and serves as a stiffener or reinforcement for the corner.  In a preferred construction the rail and flange are the respective arms of a generally V-section elongate member enclosing the corner of the girder.

Abstract: ABSTRACT OF THE DISCLOSURE      A collapsible concrete tunnel liner section formed from a number of arcuate segments each connected together by hinges to form a closed loop.  In collapsed condition the segments are arranged in a compact stack having a cross section less in its maximum dimension than the internal diameter of the erected liner section.  Typically the stack has the appearance of a figure 8, having upper and lower cavities.  Air bags are located within these cavities and are expanded to expand the collapsed tunnel liner section into its erected condition.  During the expansion the liner section passes through an oversized condition before assuming its final erected condition. This ensures stability for the erected liner section.  After erection, grout or other filler material is inserted between the liner section and the wall of the tunnel.

Abstract: CHARGE TRANSFER DEVICE DIFFERENCING CIRCUIT                  ABSTRACT OF THE DISCLOSURE A circuit is disclosed for obtaining an output signal proportional to the difference between two charge packet quantities nondestructively.          The preferred embodiment includes a substrate with a potential well disposed under a floating gate electrode having charge transfer means for entering and removing charge from the potential well.  A first quantity of charge Qa which is stored in the potential well is transferred out of the well at time t1 with a resulting proportional increase in the floating gate voltage which results from capacitor coupling from the charge to the floating gate.  At a subsequent time t2 a second charge quantity Qb is transferred into the potential well and causes a proportional decrease in the floating gate voltage.  The net change .DELTA.V in the floating gate voltage that results is proportional to the difference between the two charge quantities Q  ant Qb.
