Title: Method of producing an anhydrous crystalline zirconium tetraacetate
IPC: C07C51/41
Filed: 1960-12-14
Abstract: Anhydrous crystalline zirconium tetraacetate is prepared by heating a solution of a monochlorozirconyltriacetate acetic acid complex in a mixture of acetic anhydride and acetic acid so as to drive off acetic acid and hydrogen chloride, the resulting zirconium tetraacetate which precipitates in the remaining acetic anhydride being recovered and dried.  The heating is preferably carried out at a reduced pressure of about 40-50 m.m. Hg. and a temperature of about 60 DEG C. and may be terminated when about two-thirds of the volume corresponding with that of the acetic acid originally introduced has distilled over, the remaining mixture being treated with an oxidising agent, preferably hydrogen peroxide, at about 110-120 DEG C. and atmospheric pressure to remove the residual chlorine content.  The solution of the monochlorozirconyltriacetate acetic acid complex may be obtained by (1) dissolving zirconinm tetrachloride in glacial acetic acid at 50-60 DEG C. to give a solution of a dichlorozirconyldiacetate acetic acid complex which is then treated with acetic anhydride; (2) dissolving zirconium oxychloride hydrate in acetic anhydride; and (3) dissolving polymeric zirconium oxychloride in a mixture of acetic anhydride and acetic acid. The corresponding bromides or iodides may be used in place of the chlorides.  The tetraacetate may be readily converted to soap of higher aliphatic acids such as zirconium octoate or stearate.

Abstract: 1,244,733. Creasing corrugated board. AUSTRALIAN PAPER MFRS. Ltd. 12 Sept., 1968 No. 43331/68. Heading B6J. A method of forming creases in corrugated board having an outer liner, an inner liner, and a corrugated reinforcing member therebetween comprises forming one substantially straight crease in the outer liner, and a substantially straight creased zone in the inner liner and corrugated member, the zone being parallel to the crease but relatively disposed as to provide a hinge which is asymmetric in crosssection, wherein the zone is of a width which allows inward deformation of the inner liner and corrugated member during bending or folding, without cracking or bulging. The creased zone may be formed of a primary and secondary crease disposed on laterally opposite sides of the outer liner crease with the primary crease of greater depth than the secondary (Fig. 12, not shown) by laterally offsetting the outer liner crease from the inner liner crease (Fig. 15, not shown), or by forming the laterally offset creases with shoulders of suitable shapes (Fig. 17, not shown). The creasing apparatus comprises co-operating die-wheels having shapes and arrangements suitable for the above formations (Figs. 8-11, 14, 16 and 17, not shown). The creases can be formed in the machine direction, e.g. across the corrugations, or parallel to the corrugations.

A pressure-fired steam boiler comprises one or a plurality of elements each consisting of a pressure-resistant, vertically-disposed, cylindrical outer casing within which is coaxially located a hollow body bounded by contiguous vaporizing tubes and having a combustion chamber in its lower portion and one or more heat exchangers in the portion thereabove, the annular space between the body and the casing being swept by the air of combustion and containing the distributer and collector headers of the heat exchangers. In the form shown the outer casing 1 has hemispherical end covers 2 and contains an inner body 3 formed of small diameter, contacting steam generating tubes extending between distributers 8 and collectors 9. The lower part 6 of the body 3 is cylindrical and forms a combustion chamber fired by burners 39 whilst the upper part 7 is of square section and forms a convection pass for the combustion gases, banks of horizontally disposed tubes constituting an evaporator 12, low and high temperature superheaters 17, 23 and a reheater 30 being located in the pass. The gases discharge through an outlet 40. Air for combustion enters the easing through an upper inlet, not shown, and passes to the burners through the space between the casing 1 and the body 3. The contiguous tubes forming the body are enclosed in a gas tight sheet metal casing 4 and are supported by stiffening rings 5, the whole unit being supported from the bottom on feet 42 so that the body 3 can expand and contract independently of the casing. In operation water enters the distributers 8 through pipes 10 and flows upwardly in the contiguous tubes and through the evaporator 12 to collectors 9, 16a. The water-steam mixture flows thence to an external steam and water drum, which is common to all the boiler elements where a plurality of these is used. Steam returns from the drum to the superheater 17 and flows thence through a desuperheater 22 and the final superheater 23 to a turbine. Steam to be reheated enters the casing through a header 33, flows through the reheater and returns to the turbine via a header 28.
