International Classification:

B05D 302

US Classification:

427226

Abstract:

The present invention provides a method of decorating a ceramic article including: providing an ink composition including a metallic soap, the ink composition being a viscous oil or waxy solid at about 25Â C. ; heating the ink composition to reduce its viscosity to less than about 40 centipoise; depositing micro-droplets of the heated ink composition upon the ceramic article; and firing the ceramic article in an oxidizing atmosphere. In the most preferred embodiment of the invention, the ink composition is substantially solvent-free.

Abstract:

A method for the synthesis of mixed metal oxide crystalline powders comprises the steps of preparing a raw material mixture containing at least two different metal cations; adding a template material to the mixture and blending it therewith; initiating formation of a mixed metal oxide by calcination of the mixture and the template material, whereby particles of the mixed metal oxides are formed; and thereafter recovering the mixed metal oxide particles. Mixed metal oxide crystalline powders comprise a template material; and metal oxides which form pigment classes of material containing the template material, the pigment classes being selected from the group consisting of borate, garnet, olivine, phenacite, phosphate, priderite, pyrochlore, sphene, spinel and zircon, as well as perovskite crystal classes of material containing the template, all of which have a uniform particle morphology and particle size ranging between about 0. 2 to 100. mu. with minimal comminution.

International Classification:

B60C 1702
B60C 1704
B60C 508

US Classification:

152158

Abstract:

A pneumatic tire with an internal toroidal safety structure that expands and provides emergency support between the tire tread and the wheel rim if the tire loses inflation pressure. The safety structure has an outer circumferential belt comprising one or more superposed layers of cord reinforced strips, the belt being secured to the safety structure in a relatively narrow central circumferential zone so that radial expansion of the toroidal safety structure is readily accommodated should the tire lose inflation pressure. The belt bears between the inner surface of the tread portion of the tire and the safety structure in the event of tire deflation or underinflation and thus guards against puncture. The safety structure may be an internal inflatable tube or a flexible resilient foam member, for example.

US Classification:

106479

Abstract:

This invention relates to colorants represented by the formula Bi. sub. 2 A. sub. x-1 D. sub. x O. sub. y wherein: A is selected from the group consisting of Bi, Ba, Sr, Ca, Y, La, or a mixture of two or more thereof; D is selected from the group consisting of V, Mo, Mn, Ti, Ta, Nb, W, Sb, Fe, Cr, Sn, Ce, or a mixture of two or more thereof; x is a number that is at least 1; and y is the number of oxygens needed to fulfill the valence requirements of Bi, A and D; with the proviso that when A is Bi, D is other than a mixture consisting of V and Mo. These colorants are useful in providing colored compositions including: organic compositions such as plastics, rubbers, and the like; inorganic compositions such as ceramics, porcelain enamels, and the like; and coating compositions such as paints, printing inks, and the like; etc. The invention also provides for processes for making such colorants and for making such colored compositions. The invention also provides for such colorants in the form of particulate solids (e. g.

International Classification:

B60C 1704

US Classification:

152158

Abstract:

A pneumatic tire assembly is capable of supporting a vehicle wheel rolling for a limited distance when the air in the assembly has escaped. The tire of the assembly is prevented from going completely flat by an annular insert, preferably of a high modulus elastomeric material, that is placed inside the tire and fits over the wheel rim and between the beads of the tire. The annular insert is of a novel construction that is lightweight and flexible enough to be stretched over a conventional rim, yet is able to support the load normally borne by the inflated tire and also resists unseating of the beads.

Abstract:

This invention relates to a process for making a bismuth-vanadium-molybdenum-containing composition comprising: (A) preparing three separate aqueous compositions comprising: a first aqueous composition having a pH in the range of about 0. 5 to about 4; a second aqueous composition comprising bismuth and having a pH in the range of about 0. 2 to about 3; and a third aqueous composition comprising at least one salt of vanadium and at least one salt of molybdenum and having a pH in the range of about 9 to about 14; (B) adding said second aqueous composition and said third aqueous composition simultaneously to said first aqueous composition to form a fourth aqueous composition, and maintaining said fourth aqueous composition at a temperature in the range of about 30. degree. C. to about 90. degree. C. for up to about 4 hours, said fourth aqueous composition comprising precipitated solids; (C) separating said solids from said fourth aqueous composition; and (D) heating said solids at a temperature in the range of about 250. degree.
