Synthetic paper comprising a film base material formed from a thermoplastic resin and a filler composed of a large number of fibrous filaments and a pigment and uniformly scattered over the base material, the dispersed filaments and pigment having void spaces therearound, so that the resultant synthetic paper as a whole presents a whitish opague texture similar to Japanese paper, with a large amount of white threadlike patterns all over the base material.

Method for making a zeolite having the structure of offretite, consisting of reacting in a closed container under autogenous pressure in the absence of tetramethylammonium ions, a composition having specific mole rations of K.sub.2 O,Na.sub.2 O,SiO.sub.2, Al.sub.2 O.sub.3, and H.sub.2 O.

A solid, slate-like product, a composition and method of producing the same comprising a substantially uniform mixture of at least five parts by weight of a finely divided taconite iron ore material containing at least about 1 percent magnetite therein and an amine-formaldehyde resin such as urea-formaldehyde or melamine-formaldehyde. The mixture, heated under pressure, forms a dense slate-like material.

The present invention provides synthetic fuels, additives for use in preparing synthetic fuels and methods for producing synthetic fuel. The synthetic fuels include low levels of a chemical change additive selected from the group consisting of alkaline earth oxides and hydroxides and mixtures thereof. In one embodiment, the synthetic fuel further includes low levels of a second chemical change additive, which is a petroleum hydrocarbon material.

A fibrous body simulating natural bird down in its physical and functional aspects in that it is light in weight, has equivalent insulating characteristics, will not mildew or become soggy in the presence of water, has excellent laundering and dry cleaning characteristics, is lower in cost and is not dependent on the vagaries of nature which may result in periodic short supply.

Synthetic penicillins of the formula ##SPC1## Wherein R.sub.1 and R.sub.2 are hydrogen, alkyl, cycloalkyl, aralkyl or unsubstituted or substituted phenyl, pyridyl, naphthyl or thienyl or alternatively, R.sub.1 and R.sub.2 together form a polymethylene group, and pharamaceutical salts thereof, useful as antibacterial agents, and especially against Gram-positive and Gram-negative bacteria, are prepared by reacting 6-aminopenicillanic acid or a silylatyed derivative thereof with an acylating agent ...

A hydraulic fluid consists of, or comprises a synthetic orthoester, or a mixture of synthetic orthoesters, having the general formula represented by A or B: ##SPC1## wherein R.sup.1, R.sup.2 and R.sup.3 are specified groups. Also described are methods of making compositions which comprise a major proportion of the synthetic orthoesters and novel synthetic orthoesters of the formula: ##SPC2## Wherein R.sup.4 and x are specified groups.

A synthetic suede product formed of a thermoplastic foam adhered to a fibrous substrate, wherein the foam has the surface characteristics of natural suede. The synthetic suede product is formed by removing a surface layer of the foam so as to expose the pore structure thereof.
