Abstract: An improved load restraint system and method for protecting and supporting loads, such as cargo, especially during transit movement. The load restraint system and method compensates for various attitude, altitude and ambient pressure changes while maintaining sufficient restraining supportive force on the cargo. One embodiment maintains ambient pressure sensing with pressure/volume fluid compensation to an inflatable bladder responsive to ambient pressure changes within the cargo container. Another embodiment permits inflation of a rigidifying bladder to provide in-situ rigid support for the cargo, included during ambient pressure changes within the cargo container.

Abstract: A novel polishing slurry for particularly hard materials such a silicon carbide has been found. The slurry comprises diamond particles with a median particle size of around a micron and alpha alumina particles with a median size of from about 20 to about 200 nanometers.

Abstract: Vitrified bonded abrasive bodies prepared from sol gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by treating the surfaces of the grit particles so as to give them silica-enriched surfaces.

Abstract: Vitrified bonded abrasive bodies prepared from sol-gel sintered aluminous grit particles and a vitreous (glass) bond exhibit improved abrasive performance by coating the surfaces of the grit particles with a metal oxide, preferably by means of an organofunctional metal-containing surfactant having a metal content of at least about 10 weight percent.

Abstract: Coated abrasive material for fine finishing applications including second fining ophthalmic application, having patterned surface coating of abrasive grains dispersed in radiation-cured adhesive binder. The patterned surface coating is defined by a plurality of formations of such abrasive/binder each having an inner bottom edge defining an area devoid of coated abrasive, a top edge defining a somewhat larger area devoid of coated abrasive and an inner wall connecting the top and bottom edges.

Abstract: Particles of agglomerates of abrasive particles held in a porous glassy matrix are produced by mixing abrasive grits with known porous-glass forming compositions. In the resulting product the abrasive grits are held encapsulated within the thin walls of the porous body and tend to concentrate at the periphery of the body.

Abstract: An aqueous slurry comprising an intimate mixture of colloidal silica, (preferably an amorphous, precipitated, hydrated silica), caustic potash, boric acid and alumina is first prepared and then dried. The dried aggregates are thereafter crushed, calcined and rapidly quenched. It is preferred to dry the slurry in a spray drier and thereafter omit crushing after drying and to calcine the dried admixture by means of a plasma arc so that the mixture is rapidly quenched after calcination. The calcined mixture is introduced into a crusher, such as a ball mill, with a carbonaceous cellulating agent and reduced to a fine pulverulent material. The pulverulent material is then cellulated in a cellulating furnace to form cellular borosilicate bodies. Where desired, the calcined material may be utilized as a ceramic frit.

Abstract: Particulate casting material is applied onto the upper surface of molten steel in a vertical continuous casting mold where it rapidly melts to form a protective flux-lubricant molten glass covering which also flows down between the solidifying cast steel and the mold wall. Casting material is a substantially chemically homogeneous, pre-reacted, but substantially unfused mixture of multiple crystalline phases and preferably in a thorough blend of the mixture with up to 10% by weight finely divided graphite. The mixture: (a) analytically consists essentially of, by weight thereof, 20-45% SiO.sub.2, 10-40% CaO and/or SrO and/or BaO, 0-10% Al.sub.2 O.sub.3, 0-11% Fe.sub.2 O.sub.3, 5-25% Na.sub.2 O and/or K.sub.2 O, 0-15% MgO and 3-15% F ion; (b) exhibits not more than 2% weight loss upon heating thereof at 900.degree.C. for 1 hour; and (c) uniformly melts at temperatures of molten steel to form a fluid glass having the following viscosity characteristics: 1-80 poises at 1100.degree.C., 0.1-3 poises at 1500.
