摘要： Ceramic abrasive grits are formed by an impregnation process that involves preparing an alumina hydrate sol, drying the sol to form a porous solid, crushing the solid to produce particles, calcining the dried particles, preparing a mixture of an additive metal oxide or its precursor in a liquid vehicle, impregnating the mixture into the calcined particles, drying the impregnated particles, calcining the dried impregnated particles, and firing the particles to produce ceramic abrasive grits. The concentration of the modifying additive metal is greater at or near the surface of the grit than at the interior of the grit.

摘要： Thin film magnetic head structure includes digital read/write heads and analog read heads integrated on a single substrate. The "wrap around pole effect" is reduced or eliminated by having the thicknesses of the digital lower flux guides and the analog read gap-defining layer approximately the same, resulting in improved signal output from the digital read heads. The structure is useful in cassette decks designed to play both digital and analog compact cassettes.

摘要： An improved prepackaged, inexpensive firebox for sale at retail stores for use in outdoor cooking on consumer supplied backyard grills or for use as a quick campsite campfire starter firebox or as a prepackaged firewood firebox for fireplaces or the like. The repackaged firebox is lightweight, portable, manageably sized for easy storage, semi-fire retardant, water repellant and completely fire consumable and can be used conveniently and safely by a novice consumer. The firebox is comprised of a specially designed cardboard container and a special arrangement of prepackaged layer combustible with kindling points varying sufficiently to ignite and maintain ignited a primary combustible layer such as hardwood mesquite logs found in the southwestern United States. The special arrangement of the layered combustibles produces a tieing effect within the cardboard container and further exert counter pressure against the top and bottom walls of the closed container in order to sustain rough treatment during shipment while maintaining the desired end use layered arrangement of the combustibles for starting a fire.

摘要： An improved magnetic data transducer having a short gap with improved performance during writing, and substantially unaffected performance during reading. This is accomplished by placing one or more of the turns of the winding in the gap, occupying a fraction of the gap adjacent the transducing face. This simulates increasing gap reluctance during writing, by causing increased flux fringing.

摘要： Refractory catalyst supports are secured in metallic containers having different coefficients of thermal expansion by providing at least one layer of a resilient thermally resistant inorganic sheet material or paper between the support and casing and securing the paper and catalyst support in the container by foaming an inorganic material in the space between the sheet material or paper and catalyst support. A further layer of sheet material or paper may be provided adjacent the support with the foam between the separate layers of sheet material.
