Abstract: A toy doll includes a sound reproducing device having a rotatable grooved record and a transmission for rotating the record in a predetermined direction upon oscillation of the doll's arm. A tone arm bearing a needle is supported in the doll's body for engagement with the record and has one end thereof engaged against a sound reproducing diaphragm. The diaphragm is mounted for movement towards and away from the record in response to selective positioning of the doll's arm and is operatively engaged with the tone arm to draw the tone arm away from the record when the diaphragm moves away from the record, while permitting the tone arm to move along the surface of the record as the needle tracks in the grooves thereof. A spring arrangement normally holds the tone arm engaged with the record, and applies a biasing force biasing the record towards the start position.

Abstract: A bobbin carrier includes a rectangular frame having adjustable support shafts mounted at the corners thereof which, in turn, individually adjustably support brackets, each of which includes means for adjustably and slidably positioning thereon a pair of support rods adapted to receive large yarn bobbins. Yarn bobbins supported upon the carrier are selectively aligned, and spaced uniform distances from generally centrally located first guide means resulting in uniformity of feed of yarns to a machine which utilizes the yarns. Bobbins may be replaced by slidably retracting the support rods relative to the bobbin and the brackets.

Abstract: A process for liquid-liquid ion exchange of alkali metal ions. An alkaline aqueous phase containing potassium ions together with other alkali metal ions is contacted with an organic phase containing a polyol-boron-alkali metal complex. The organic phase preferentially extracts potassium values from the aqueous phase. The potassium values are separated from the polyol-boron-alkali metal complex by, for example, stripping with dilute sulfuric acid.

Abstract: An improved system for deashing coal liquefaction products wherein a feed mixture (including a deashing solvent, soluble coal products and insoluble coal products) is separated in a first separation zone into a first light fraction and a first heavy fraction (including insoluble coal products and some deashing solvent). The first heavy fraction is withdrawn from the first separation zone and the pressure level of the first heavy fraction is reduced at least 100 psig for vaporizing the deashing solvent and for yielding a composition substantially comprising coal products. The composition is essentially a powdery, solid material and is capable of being transferred via a slurry or mechanical means.

Abstract: This invention relates to a process for producing coal derived, hydrogen-rich donor fractions from fractions of coal liquefaction products for use in the hydroconversion of coal. Coal liquefaction products are subjected to a critical solvent deashing process to produce various deashed coal fractions which can only be obtained by practicing that process. Thereafter, the various deashed coal fractions are subjected to hydrogen addition to produce heretofore unavailable hydrogen-rich donor fractions. These hydrogen-rich donor fractions may be recycled to supplant a portion of the liquefaction process solvent or blended with other fractions produced by the deashing process to provide improved fuel products.

Abstract: An improved coal deashing process wherein a feed mixture comprising soluble coal products, insoluble coal products, and deashing solvent at a first temperature level is separated in a first separation zone into a first light fraction and a first heavy fraction comprising the insoluble coal products and some of the deashing solvent through admixing predetermined quantities of an additive with the feed mixture prior to separation to provide an improved yield of recoverable soluble coal products. Alternatively, the additive is admixed with the first light fraction prior to subsequent separations to provide an improved yield of recoverable soluble coal products.

Abstract: A coal deashing process wherein a feed mixture comprising soluble coal products, insoluble coal products and solvent is separated in a first separation zone into a first heavy phase and a first light phase comprising soluble coal products, solvent and some insoluble coal products. The first light phase is withdrawn and introduced into a second separation zone wherein it separates into a second heavy phase comprising insoluble coal products, soluble coal products and some solvent and a second light phase comprising soluble coal products and solvent. The second heavy phase is withdrawn and at least a portion is recycled to the first separation zone to increase the yield of separable soluble coal products ultimately recovered by the process.

Abstract: A cross connect panel having a switchable slider assembly for positive engagement and disengagement of the loads to the supply buses. A resilient detent mechanism is provided for positive indexing of the slider assembly in alignment position with the various supply buses. The parallel supply buses are held in place by a system of bus holders and interlocking spacers and the bus bar assembly is held together by bolts through the interlocking spacers, thereby avoiding the necessity of drilling bolt holes in the bus bars and providing proper insulation therefor.

Abstract: A device supported by a vehicle frame for engagement with a leaf spring, attached to the rear axle of the vehicle, to increase the resistance afforded by the spring in supporting the rear part of the vehicle frame and the load carried thereby.

Abstract: A method of lowering undesirable vehicle exhaust emissions includes preparing a catalyst for use in the exhaust stream of the vehicle. The method includes impregnating one group of alumina substrates with platinum, impregnating another group of alumina substrates with palladium, and the mixing the first and second groups of impregnated substrates.

Abstract: An improved coal deashing process wherein coal is mixed with a first dissolving solvent, heated, solubilized and flashed to provide a prepared mixture. The flashing is effected at a temperature below about 650.degree. F. to increase the amount of the first dissolving solvent in the prepared mixture. The prepared mixture then is mixed with a second dissolving solvent to produce a feed mixture which is subjected to two or more successive phase separations. Insoluble coal products present are separated from the feed mixture in a first separation zone and the soluble coal products are recovered from the first and the second dissolving solvents in a second separation zone. The second dissolving solvent is recovered from the first and the second heavy fractions and the second light fraction for recycling to aid in producing the feed mixture. The first dissolving solvent is recovered from the first and second flash zones.

Abstract: Hollow molded plastic support member for use in forming a variety of traffic warning devices has an inverted Y-shape which forms a pair of spaced angled legs and a vertical post portion. The post portion includes a pair of vertically elongated, spaced apertures defined by integral plastic connecting walls which space the opposed planar side portions of the support member from each other. An opening in the post portion permits ballast to be loaded into the hollow interior of the legs. A single support member can be used in combination with a vertical member having portions which snap fit with the apertures to form a three-legged sign or light support. Pairs of support members can be used with a variety of disclosed cross bar arrangements to form barricades and warning signs. The snapfit design of several of the disclosed warning devices permits the devices to come apart when hit by a vehicle without causing damage to either the vehicle or the warning device.
