An improved three-section convertible sofa mechanism for installation in a convertible sofa. The mechanism has three sections which unfold from a sofa configuration into a bed configuration. The conversion is assisted by a motor-operated pair of bellows which assist in the lifting and positioning of the mechanism during the unfolding operation. The front edge of the convertible sofa and of the bed...

By the vapor phase reaction of benzene or a monoalkylbenzene with an alkylating agent in the presence of a specific catalyst obtained by subjecting a zeolite to a treatment with a gas containing a silicic acid ester and then a calcination in an oxygen-containing gas, said zeolite being 10 or more with respect to its molar ratio of SiO2/X2O3 in which X is at best one member selected from the group ...
