Abstract: A method for treating synthetic pulp particles, which includes treating a slurry of synthetic pulp particles having a Schopper-Riegler freeness of more than 30.degree.SR by a concentration provided with a rotary filter bed to lower the freeness not more than 30.degree.SR, water-washing the synthetic pulp particles in the state where the freeness is not more than 30.degree.SR, and dispersing the synthetic pulp particles in water to restore the freeness to more than 30.degree.SR.

Abstract: A transmitter for a radio remote control system for a model drive unit such as a model plane capable of eliminating a necessity of corresponding a plurality of controlled objects to one transmission section while replacing them one by one, as well as eliminating a necessity of switching between wiring connections in the transmission section even when the transmission section is commonly used in view of a custom of control varied depending upon a state, to thereby facilitate the operation of changing channel allocation without malfunction.

Abstract: A radio remote control system for a model drive unit such as a model plane or the like is disclosed which is capable of eliminating retrimming of the same controlled object of which the trim adjustment was completed to substantially simplify the troublesome trim adjustment. The system includes a trim control voltage code memory which serves to separately readably stores therein trim control voltage codes representing trim control voltages of trim controllers concerned with a previously controlled object, so that the trim control voltage codes corresponding to the positions of the trim controllers during the previous control operation may be read out from the memory during recontrol of the previously controlled object. The system may also include a digital adder for carrying out addition of the trim control voltage codes of the previously controlled object read out from the memory and the trim control voltage codes concerned with the same controlled object currently controlled.

Abstract: A cake of synthetic fibrid, which is formed by pressing to hydroextract a slurry of synthetic fibrid, pulverizing the compression product, and compressing the pulverization product again to solidity it in the form of a plate-like cake.

Abstract: Disclosed is a process for the recovery of aromatic carboxylic acid or ester thereof from the residue fraction of the oxidation or esterification reaction mixture resulting from the oxidation or oxidation and esterification of an aromatic compound having at least one methyl or formyl group directly bonded to a ring carbon atom. The process comprises treating the residue fraction with hydrogen and a hydrogenation catalyst.

Abstract: A resin composition for electrocoating which comprises(I) a reaction product (G) of an epoxy compound (E), optionally an epoxy group-modifying agent (F) and a partially esterified and/or partially amidated product (D) which is obtained by partially esterifying and/or partially amidating an adduct (A) of a conjugated diene polymer with an .alpha.,.beta.-unsaturated dicarboxylic acid or its anhydride with an alcoholic hydroxy group-containing compound (B) and/or a primary or secondary monoamine (C), respectively, and(II) a completely blocked organic polyisocyanate,said mixture of the reaction product (G) and the completely blocked organic polyisocyanate being neutralized, ora neutralized product of an adduct (H) of the reaction product (G) with a partially blocked organic polyisocyanate.The resin composition is applicable to electrocoating, particularly cathodic electrocoating, and hence, is useful for electrocoating of steel products, particularly for electrocoating of automobiles.

Abstract: Process for producing liquid polymer which comprises polymerizing a conjugated diene or copolymerizing a conjugated diene with an aromatic vinyl compound in the presence of 0.01 to 100 mol of ethylene and/or propylene to 1 mol of the conjugated diene in the presence of a catalyst system comprising:1. at least one nickel compound and2.a. an alkylaluminum halide orb. a combination of (b.sub.1) at least one organometallic compound and (b.sub.2) at least one halogen compound, and optionally as the third component3. (a') a phosphorus compound, (b') a nitrogen compound, (c') ethers, or (d') a sulfur compound.
