Abstract: This invention relates to the preparation of small spheroidal solid agglomerates. More particularly, the process produces strong solid speroidal agglomerates containing alumina or a mixture of alumina and at least one other inorganic material, which process comprises:
     (a) mixing at high speed a portion of alumina or a mixture of alumina and at least one other inorganic material in the form of hydrophilic micron-sized particles in a water-immiscible liquid thereby forming a dispersion;   (b) gradually adding to the dispersion an aqueous acidic phase while continuing the high-speed mixing until substantially spherical micro-agglomerates form within the water-immiscible liquid;   (c) subjecting the micro-agglomerates to agitation in a vessel having a hydrophobic inner surface at a speed low enough to achieve substantially uniformly sized sper6idal agglomerates;   (d) drying the agglomerates to produce hardened spheroidal uniformly sized agglomerates; and   (e) optionally further separating the agglomerates by size. Optionally, the aqueous phase in step (b) may include the soluble salts of catalytic metals, and bases and/or colloidal-sized inorganic particles. These spheroidal particles can have either smooth surfaces or polylobe surfaces depending on the conditions of preparation. They have diameters generally between 1 to 5 mm and are useful as catalysts, or catalyst supports. Catalytic components may subsequently be deposited on the support.

Abstract: A magnetoelastic torque transducer for providing an electrical signal indicative of the torque applied to a member, the member including ferromagnetic, magnetostrictive means affixed to, associated with or forming a part of the surface of the torqued member for altering in magnetic permeability in response to the application of torque to the member. The ferromagnetic, magnetostrictive means is advantageously formed of a thermally hardened or iron-nickel martensite hardenable steel alloy characterized by a substantially isotropic magnetostriction having an absolute value of at least 5 ppm and including from 0.05 to 0.75 percent by weight carbon and sufficient of one or more elements selected from Ni, Cr, Co, Ti, Al, Mn, Mo, Cu and B to raise the alloy magnetostriction to at least 5 ppm absolute. Preferably, the ferromagnetic, magnetostrictive means is formed of nickel maraging steel. The transducer comprises a pair of axially spaced-apart annular bands defined within a region of the ferromagnetic, magnetostrictive means, the bands being endowed with residual stress created, respectively symmetrical right and left hand helically directed magnetic anisotropy of sufficiently large magnitude that the contribution to total magnetic anisotropy of any random anisotropy in the member is negligible. In one aspect of the invention, each said band has at least one circumferential region which is free of residually unstressed areas over at least 50% of its circumferential length. In another aspect of the invention, the alloy is thermally hardened before the bands are endowed with the residual stress-created magnetic anisotropy.

Abstract: A three-step reaction process for ultimately preparing isocyanatoalkyl esters. The first step involves the reaction of an amino alcohol and dimehtyl, diethyl or dipropyl carbonate to produce an N-hydroxy-alkyl-O-alkyl urethane. The second step may involve the reaction of the already produced N-hydroxy-alkyl-O-alkyl urethane with an ester of a carboxylic acid in the presence of a catalyst such as 1,4-diazabicyclo-(2, 2, 2)octane to produce a urethano ester in the form of an alcohol blocked isocyanatoalkyl ester. The third step may involve the pyrolysis of the already produced urethano ester to yield an isocyanatoalkyl ester. Each step of the reaction may be preformed separately or in sequence.

Abstract: There is disclosed herein an apparatus and method for generating a first signal related to the rate of change of a second signal. In particular, a system is disclosed for generating a velocity signal in a sampled data servo system. The apparatus uses three track and hold amplifiers one of which is also a difference amplifier to sample the position error signal at selected times. A "present" track and hold amplifier samples and holds the position error signal during the current frame. After this is done, during the same frame, a "summing" track and hold amplifier having its difference inputs coupled to the outputs of the "present" track and hold amplifier and to a "previous" track and hold amplifier samples the difference between the present position error signal and the value of the position error signal during the previous sample frame. This difference divided by the sample period gives the velocity. After the difference value is sampled, the "previous" track and hold amplifier sample is updated to the amplitude of the position error signal during the current frame in preparation for the calculation during the next frame.

Abstract: A method and a device for determining the content of components dissolved in a solvent. An osmotic cell is used in which a working pressure is first established by an (external) reference solution and then the pressure variation established in the cell is determined after replacing the reference solution by the solution to be examined. The object is also to determine the contents of components present in high concentration with very high absolute accuracy. For this purpose, an osmometer solution is chosen which contains an excess of not more than 80 mOsm compared with the reference solution and which contains the components to be determined in a concentration such that the difference in the contents of the components in the solution to be examined and in the osmometer solution does not exceed 70 mOsm. The total content of the components is then determined taking account of the content of the components in the osmometer solution. To determine very small variations in the components (less than 20 mOsm) the temperature of the solutions is kept constant at the measurement site, for which purpose a suitable device is provided.
