Abstract: PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS                 ABSTRACT OF THE DISCLOSURE         A process starting from a hydrocarbon feedstock, and aiming to produce a synthesis gas suitable either for methanol synthesis or for other applications requiring a low H2/CO ratio.          In this process, the feedstock is first desul-furized if necessary, then divided into two fractions; a first fraction undergoes a primary steam reforming at high pressure and moderate temperature; the gas effluent from said primary steam reforming, as well as the second fraction of the feedstock, subsequently undergo jointly a secondary reforming by reaction with an oxygen contai-ning gas in a reactor operating under essentially adia-batic conditions.          The synthesis gas obtained as effluent from said secondary reforming, has a composition adjustable at will in a wide range, and therefore can be made as close as necessary to the stoechiometric composition required for methanol synthesis, or has a low H2/CO ratio for other applications, and this synthesis gas is available at high pressure, and can therefore feed directly, without com-pression, the synthesis loops downstream.          The process of the present invention is particu-larly suitable for methanol production on a very large scale.

Abstract: Abstract of the Disclosure The invention is used in an optical spectrometer having a monochromator with entrance and exit ports and a grating, and relates to an improved method and means for aligning a focusing mirror so that an optical beam can be easily and accurately focused on the entrance or exit ports of the monochromator or on its grating.  The mirror is mounted in a block with bores adapted to receive bushing assemblies each with a plurality of pairs of matching female and male circular spring rings positioned about a shaft for contact in expanded condition with the bore.  Conical surfaces of the rings are in wedging contact with each other, each of the rings being split by a slot extending entirely through the wall of the rings longitudinally of the axis.  Each of the rings is constructed and arranged for angular, longitudinal and radial movement relative to each other on the shaft when a longitudinal compressive force is exerted on the rings to adjust the longitudinal and radial positions of the male and female rings by expanding the female rings and contracting the male rings.

Abstract: ABSTRACT OF THE DISCLOSURE            Apparatus for removing floating material from the surface of a body of liquid and for collecting the material has an endless belt-type materials transport mounted, as by rollers with vertically-separated horizontal rotation axes, to dispose the transport with a lower flight inclined downwardly from above the liquid surface at a frontal location to below the surface at a rearward location.  A collection well is contiguously behind the rearward location.  The transport is driven to advance the lower flight in the direction from the frontal location to the rearward location.  This motion carries floating material from the liquid surface downward and rearward under the lower flight of the transport and releases it at the rearward location to float upward into the collection well.

Abstract: ROTATABLE SLEEVE RACK                    ABSTRACT OF THE DISCLOSURE    An improved variable ratio steering apparatus is used to effect turning movement of steerable wheels of a vehicle.  The apparatus includes a longitudinally extending force transmitting member or bar which is connected with the steerable vehicle wheels.  A drive member is rotatably mounted on the bar.  In order to effect axial movement of the bar and turning movement of the vehicle wheels, a pinion gear is disposed in meshing engagement with an array of helical rack gear teeth on the drive member.  A cam track is also provided on the drive member.  This cam track is coextensive with the array of rack gear teeth.  The cam track cooperates with a follower to effect rotational movement of the drive member as the drive member and force transmitting bar are moved axially.  This rotational movement of the drive member causes an interaction between the pinion and rack gear teeth to vary the rate of axial movement of the drive member and the force transmitting bar.  The follower advantageously engages the cam track at a location which is axially aligned with the location where the pinion gear is disposed in meshing engagement with the rack gear teeth.  This tends to minimize deflection of the components of the steering apparatus.  Although an apparatus constructed in accordance with the present invention is advantageously used to turn the steerable wheels of a vehicle, it is also contemplated that the apparatus can be used in other environments.

Abstract: SCREEN APPARATUS FOR SORTING FRAGMENTED MATERIAL     ABSTRACT OF THE DISCLOSURE        An improved Sorting Apparatus of the Harp Screen variety utilizes a plurality of elongated, parallel wire spac-ing strips positioned along a frame and carried on individual beams which are oriented perpendicular to a multiplicity of tensioned wire lengths extending between wire retaining means at opposed ends of the frame.  Each spacing strip has a substan-tially arcuate, convex upper face with a multiplicity of V-cross section wire receiving guideways which are equally spaced there-along to maintain a predetermined distance of separation between the wire lengths.  Each guideway has an arcuate floor which has a convex arch configuration which supports the wire length at the apex of the arch and then drops downwardly to thereby minimize destructive abrasion between wire and guideway floor.  The guide-way construction tends to reduce wear of the guideway in lateral directions and to utilize normal wear to more firmly seat the wire in the guideway and retain desired spacing between adjacent wires.  An improved retaining means is also provided to retain and permit easy tensioning of the wire-length.

Abstract: ABSTRACT OF THE DISCLOSURE   A converter arrangement secure against breakdown, having electronic power circuitry using controlled valves and electronic information-processing control circuitry.  The electronic power circuitry is provided only once, but the electronic information-processing circuitry is redundant and contains at least two complete control units.  One unit leads and controls the electronic power circuit and at least one other unit operates in parallel, in standby condition.  A monitoring device is associated with the control units and, in the event of a disturbance in the leading control unit, switches control of the electronic power circuit to an undisturbed control unit.  The arrangement is especially suitable for use in protected converter arrangements which provide interruption-free supply of a load, having the advantage that the expensive electronic power circuitry is provided only once and is not operated in partial-load operation.
