Abstract: TORQUE CONVERTER TRANSMISSION                   Abstract of the Disclosure An angle drive transmission having an angle drive input shaft and bevel gearset driving an input sleeve shaft supported on each side of the driven bevel gear by bearings in an end wall and a central wall of the main housing.  The sleeve shaft drives a pump mounted on the end wall and extends through the end wall to drive and support the clutch wall of an outboard-mounted rotary torque converter housing.  An outboard cover housing has its open end secured to the main housing at the end wall, encloses the rotary housing, and has a central ground member rotatably supporting the impeller wall of the rotary housing.          The torque converter has a bladed impeller on the impeller wall, a bladed turbine adjacent the clutch wall connected to an output shaft rotatably mounted in the sleeve shaft, and a bladed stator between the impeller and turbine mounted on the ground member.  A lock-up clutch between the clutch wall and turbine, in lock-up, connects the rotary housing to drive the output shaft.  The pump and a regulator valve in the end wall supply fluid by an internal central supply passage provided by transfer passages through the sleeve shaft, through a passage in the output shaft to enter the entrance passage between the turbine and stator to the converter flow-path and exit by an internal central exit passage between the impeller and stator and through an outlet passage having a trans-fer passage to an external passage to a cooler.  The torque converter hydrokinetic thrust and bevel gear thrust are axially opposed and substantially equal to balance thrust load on the sleeve shaft.

Abstract: Abstract of the Disclosure A load-handling gantry having a single, unitary, bridging beam, and leg, brace and mounting components supporting said beam with provision for adjustment of gantry span, height, and spread, while maintaining gantry mobility.  The mounting components are adjustable to enable use of the gantry in a number of configurations including inboard, outboard, and combination leg bracing, and with freedom for use under cantilever conditions.  In the preferred embodiment, a predetermined camber,  or longitudinal splay angle, of the plane of each pair of legs is provided, to decrease movement between the gantry legs and the beam, in the direction lengthwise of the beam, when the gantry is under load, thereby stabilizing the gantry in that sense.  The selected splay angle is maintained by means which couple the leg bracing struts to the beam and to the legs.  Any selected angle, under the various arrangements of leg bracing, may be had, and may be maintained, by such coup-ling means, which provide alteration of the effective bracing strut length, without the necessity of actually substituting struts of different lengths. Lateral clearance between the beam, and the legs and bracing struts, is main-tained in the various configurations, at a value such as to permit free move-ment of the leg and strut assemblies along the length of the beam, and also a measure of lateral flexibility of the gantry.  All adjustments relative to the beam may be made through external frictional gripping means, cooperable with a standard imperforate beam.

Abstract: ABSTRACT OF THE DISCLOSURE            Pure racemic acid (d1-tartaric acid) and meso-tartaric acid are produced by reaction of an alkali maleate with aqueous hydrogen peroxide in the presence of a catalyst which is an alkali molybdate or a mixture of an alkali molybdate and alkali tungstate in a process wherein the molar ratio of hydrogen peroxide to maleic acid is greater than 1:1 and the alkali salt of cis-epoxysuccinic acid formed together with the catalyst in a given case after destroying the excess hydrogen peroxide and other peroxygen compounds, are converted to free cis-epoxysuccinic acid and free molybdic acid or mixture of free molybdic acid and free tungstic acid by leading them over a strongly acidic cation exchanger, whereupon the hydrolysis of the free cis-epoxysuccinic acid to racemic acid and meso-tartaric acid can take place either in the presence of or the absence of the free molybdic acid or mixture of free molybdic acid and free tungstic acid, whereby the catalyst in the case of catalyst free hydrolysis before, and in the case of catalyst containing hydrolysis after this hydrolysis is removed with an anion exchanger and the racemic acid is then in known manner crystallized out of the catalyst free hydrolysis mixture by lowering the temperature in a given case with evaporation of water, whereupon the meso-tartaric acid remains in the mother liquor, and there is recovered from the mother liquor either by crystallization or by evaporation to dryness, in a given case in admixture with racemic acid, unreacted cis-epoxysuccinic acid and maleic acid, while the anion exchanger laden with the molybdic acid or mixture of molybdic acid and tungstic acid is regenerated in known manner with dilute aqueous alkali and, in a given case, the resulting solution of alkali molybdate or mixture of alkali molybdate and alkali tungstate, eventually after treatment with activated carbon is returned directly into the epoxidation step.

Abstract: ABSTRACT OF THE DISCLOSURE             A die holder has adjacent to its front end an annular step portion comprising a steep wall and a gradual wall tapered from the steep wall to the front end, the annular step portion being adapted to provide an annular space be-tween the step portion and an inner surface bounding a billet receiving bore in a container when the die holder is inserted in the bore.  During indirect extrusion operation, foreign impurities such as dirt, lubricant, metal oxides, and the like deposited between the bore surface and the billet are trapped and collected in the annular space against entrinment into an extruded product being formed.  An annular ring partly defining the steep wall acts as a barrier that prevents the impurities from getting therepast and minimizes skull formation on the bore surface.  An annular butt formed by accumulations of the impurities in the space and a butt end of the billet are cut off from the container by means of a shear.
