Abstract: A baby carriage having a pair of front legs and a pair of rear legs. The pair of rear legs each have an angle bar pivotally connected thereto while the angle bar has a pusher rod pivotally connected to the other end thereof. With the baby carriage in the opened state, the angle bar is substantially in line with the associated pusher rod body. With the baby carriage in the closed state, the pusher bar body and the associated angle bar are in bent relation to each other, thus reducing the vertical dimension of the baby carriage. Further, in response to the turning movement of the angle bars relative to the rear legs, both the longitudinal and the transverse spacings between the front and rear legs are reduced. In this manner, the baby carriage is folded.

Abstract: A method of preparing large pore volume zirconia-silica catalyst supports, the resulting supports and a method of polymerizing olefins comprising contacting an olefin or mixture of olefins with a catalyst prepared with these supports. The supports are prepared by reacting a zirconium compound of the formula M.sub.4 Zr(C.sub.2 O.sub.4).sub.4.nH.sub.2 O, where M is an alkali metal or ammonium ion and n equals 0 to 10, with a silicon compound of the type A.sub.2 SiO.sub.3, where A is an alkali metal, in an aqueous solution at a pH equal to at least 11, then adding an acidic solution to a pH of about 5-9 to produce a hydrocogel. The hydrocogel is then aged and washed free of soluble by-products first with water, then with aqueous ammonium nitrate and again with water. The water is removed from the washed hydrocogel by azeotropic distillation or by washing with a water miscible solvent and then calcining the resulting xerocogel.

Abstract: A plastic body is provided for use in a container which is adapted to hold product under vacuum, without undesirable deformation of the container. The body has a curvilinear bulge at the base of its cylindrical sidewall, and the bulge is dimensioned and configured to permit its slight deflection under vacuum which, in turn, facilitates upward movement of the bottom wall of the body. These changes effect a reduction of volume within the body, thereby reducing the level of vacuum which forms therewithin. The characteristics of the body render it particularly well-suited for production in relatively small sizes, utilizing relatively rigid synthetic resinous materials. It is also especially adapted for use in connection with a metal end closure, which may be hermetically sealed thereonto.
