Abstract: APPLICATION OF: Leslie J. Kasper FOR: LOAD SENSING CONTROL FOR      HYDRAULIC SYSTEM                     A B S T R A C T            A load sensing hydraulic system is disclosed of the type in which a load signal is communicated from down-stream of a main flow control orifice to a device which is operable to vary the fluid delivery rate in response to changes in the load signal.  Disposed in the load signal conduit is a load signal modulating valve which, in one position, communicates the load signal, substan-tially unchanged, to the variable fluid source.  In another position of the modulating valve, the load sig-nal chamber of the variable fluid source is drained to tank, while in intermediate positions of the modulating valve, a portion of the load signal is communicated to the variable fluid source, and a portion is bled to tank.          Modulation of a load signal permits flow control in an hydraulic system, independent of the position or move-ment of the main spool valve.  The input to the modu-lating valve may be manual or electric, and if electric, may be remote, or may be automatic in response to certain predetermined system conditions.

Abstract: HUB CLUTCH                 ABSTRACT OF THE DISCLOSURE           An automatic roller-type hub clutch is provided with a manual device operable to override the automatic mechanism to prevent free wheeling due to overrun.  An improved resilient coupling is provided for the manual device designed to translate rotational movement from a rotatable selector to a camming device and to provide a built-in self-energizing action in both an engaging and disengaging direction.  The resilient coupling dis-closed is a coiled  torsional  spring having one end connected to the rotatable selector and the opposite end connected to the camming device. In operation, the rotatable selector is rotated in opposite directions to wind and unwind the spring causing the camming device to rotate with the rotatable selector to axially move a slidable clutch member into engagement with a fixed clutch member.

Abstract: ABSTRACT OF THE DISCLOSURE Mica filler is treated to provide a macroscopically uniform dispersal of chlorinated hydrocarbon as a coating throughout and a microspically higher level of chlorine at the edges of mica flakes in the filler.  Such filler is useful in reinforcement in melt forming resins, such as, polypropy-lene.  The treatment is effected by enveloping the mica flakes in a fluid medium that comprises chlorinated hydro-carbon having about 50 to 75% by weight chlorine and a molecular weight of about 500 to 3000 in a liquid dispersant therefor.  The mica flakes then are dried at a temperature above about25°C..

Abstract: METHOD FOR PRODUCING A DI-ACETAL OF SORBITOL AND AN AROMATIC ALDEHYDE        Abstract of The Disclosure A method is provided for producing a di-acetal of sorbitol and an aromatic aldehyde wherein an aqueous solution containing a catalytic amount of a mineral acid and sorbitol is formed.  There-after, an effective amount of an aromatic aldehyde such as benzaldehyde is incrementally admixed into the homogeneous aqueous admixture containing the sorbitol at a rate sufficient to allow a substantially spontaneous reaction to occur between the D-sorbitol and aromatic aldehyde; thus, forming an aqueous slurry containing crude di-acetal, e.g., dibenzylidene sorbitol.  The amount of aromatic aldehyde employed is that amount sufficient to provide a molar ratio of D-sorbitol to aromatic aldehyde of from about 1:.75 to about 1:1.75.  Thereafter, the aqueous slurry is neutralized, and crude di-acetal is removed from the liquid phase and washed with water to remove mono-acetal impurities, e.g., monobenzylidene sorbitol.  The washed di-acetal may then be dried to provide dried di-acetal, and the dried di-acetal may be further purified by washing with a relatively non-polar solvent.

Abstract: METHANATION OF CARBON MONOXIDE         WITH IMPROVED CATALYST REGENERATION             ABSTRACT OF THE DISCLOSURE     Carbon monoxide-containing gas streams are passed over a catalyst capable of catalyzing the disproportiona-tion of carbon monoxide so as to deposit a surface layer of active surface carbon on the catalyst essentially without formation of inactive coke thereon.  The surface layer is contacted with steam and is thus converted to methane and CO2, from which a relatively pure methane product may be obtained.  Dilute carbon monoxide-containing streams, as from underground coal gasification with air or the effluent from blast furnace operations, can be used without pre-treatment to convert the carbon monoxide and/or to separate inert gases therefrom.  Conversion of the active surface csrbon with high pressure steam enables  a high pressure product methane stream to be generated without expensive compression equipment and high energy consumption.  Nickel, cobalt, iron, ruthenium, rhenium and alloys thereof are preferred catalysts, with the surface area thereof being preferably at least about 10m2/gr.  Conversion of the active surface carbon can also be accomplished by contact with hydrogen.  Carbon monoxide-containing gas streams having hydrogen or water present therein can be used, with only the carbon monoxide available after reaction with said hydrogen or water being decomposed to form said active surface carbon.  The hydrogen or water will be converted, partially or completely, to methane which can be utilized in a combustion zone to generate heat for steam production or other energy recovery purposes.  For practical commercial operations utilizing the two-step process of the invention on a cyclic basis, nickel, cobalt, ruthenium, thenium and alloys thereof are especially prepared for use in a metal state, with CO disproportionation being carried out at temperatures up to about 350°C and with the conversion of active surface carbon to methane being carried out by reaction with steam.  The catalyst is employed in such cyclic operations without the necessity for employing a regeneration step as part of each processing cycle. Inactive carbon or coke that tends to form on the catalyst over the course of continuous operations utilizing such cyclic process is effectively and advantageously removed, on a periodic basis, in place of conventional burn off with an inert stream containing a low concentration of oxygen.

Abstract: ABSTRACT         An improved cooling system for a magnetic isolation drive coupling is described.  The coupling includes a driven magnet assembly at one end of an output shaft and which is contained in a housing hermetically sealed to a pressure vessel in which the output shaft is connectable to appropriate equipment therein.  A magnetically permeable gas barrier forms part of the housing, surrounding the driven magnet assembly.          A drive magnet assembly is contained in an annular housing surrounding the barrier and is connected to a prime mover so that rotation of the drive assembly effects rotation of the driven assembly through magnetic coupling.  A plurality of longitudinal slots in the annular housing permit cooling air to be directed onto the gas barrier to reduce the barrier temperature rise due to eddy current heating therein at high torques and rotational speeds.  With such cooling the air gap between the drive assembly and the gas barrier can be decreased to permit such high torques and rotational speeds which would, without the improved cooling feature, create unacceptable temperature rises due to eddy current heating.
