摘要:
A method of producing a feather containing resilient body to be used for a padding or a trim cover of a vehicular seat. The method is as follows: First, a predetermined amount of feathers is coated with water and prepolymer of polyurethane resin. The coated feathers are put into a mold to form a mass of feathers. In the mold, the feather mass is adjusted in thickness and heated so that the polyurethane resin prepolymer is hardened.

This invention relates to the preparation of small spheroidal solid agglomerates. More particularly, the process produces strong solid spheroidal 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 spheroidal 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.

A process is disclosed for the preparation of bleach catalysts in aggregate form. The steps comprise adsorbing a manganese (II) salt onto an aluminosilicate support; granulating with a high disrupting force an aqueous slurry of the aluminosilicate bearing manganese (II), and drying the resultant aggregates. At least 70% of the dried aggregates resulting from the process must have a diameter size from at least 250 to about 2000 microns.
摘要:
A control method for a granulating apparatus of the type in which a binder liquid is added to powder material having high moisture absorbing properties while fluidizing the powder material thereby producing granules or granular material of a desired particle size. In this control method, the moisture content of powder material to be granulated is continuously detected with a high degree of accuracy by a moisture content detector and in accordance with the detected value the rotation speed of a binder feed pump or the like is adjusted through a moisture content regulator thus varying for example the rate of addition of the binder and thereby controlling the moisture content of the powder material.
摘要:
An apparatus for drying pellets of particulate material such as carbon black is characterized by a columnar drying vessel containing inclined trays or screens positioned so that the pellets or particulates roll from screen to screen down the column. Preferably, the pellets are subjected to countercurrent flow of drying gases while flowing down the screens. In other aspects, carbon black is pelleted with a nonaqueous liquid pelleting fluid and dried with vapors of the same pelleting fluid.
摘要:
A method of making a dielectric material comprising blending in a polymer dispersion, a particulate filler material having a high dielectric constant and microfibrous material to form a slurry of polymer, filler, and fiber. A flocculant is added to the slurry to agglomerate the polymer particles, the filler particles, and the microfibers to produce a dough-like material. The dough-like material is formed into a desired shape and then subjected to heat and pressure to densify the dielectric material.

A cotton candy machine including, a base having a switch, motor and heater, and a head The head includes a shaft removably coupled to the motor and a dish coupled to the shaft. A cover is disposed between the dish and a lid. The shaft, cover and lid are in a fixed relationship relative to each other. The cover and the lid form a cavity which is configured to receive hard candy which can be melted when said dish and cover combination are heated to a predetermined temperature. The lid has a lip formed on its top surface around an inner annular ring portion of the lid. The is lip configured to enable the hard candy, when melted, and the head is rotating at a predetermined speed, to form strands or threads which are collectable as cotton candy.
