Abstract: A portable stove is provided. The stove includes a frame including an upper portion with an opening and a lower portion. A combustion chamber is positioned directly below the opening of the upper portion of the frame. The combustion chamber is defined by an inner wall, and an outer wall spaced apart from the inner wall to define a cavity therebetween. The inner wall includes a plurality of holes spaced about a periphery. A tank for oil is provided. Any oil, such as vegetable oil, can be used. A feed line directs the oil from the tank into the combustion chamber. A fan is connected to the frame and is in communication with the cavity. The fan blows air into the cavity that travels through the holes and into the combustion chamber to provide air for combustion of the oil. An ignition element is provided for igniting the oil.

Abstract: The present invention relates to a process for preparation of silane compound represented by general formula (I) of which one or two hydrogens have been substituted, comprising a reaction of silane compound represented by general formula (II) with trichlorosilane in the presence of metal or metal compound as a catalyst. ##STR1## whereby, R.sup.1, R.sup.2 and R.sup.3 respectively represent chlorine or methyl group, and Z and Z' respectively represent hydrogen or chlorine, and as a result, the process of the present invention is industrially useful because trichlorosilane having relatively low price is employed.

Abstract: There is an olefin catalyst system containing a Zielger-Natta catalyst with as an electron donor, an organosilane compound as represented by the formula (I); ##STR1## wherein R.sub.1 is trimethylsilylmethyl or 2-phenylpropyl; R.sub.2 is cyclopenty or cyclohexyl; and R.sub.3 is C.sub.1 -C.sub.3 alkyl.
