Title: Process for producing printed materials and thus produced printed materials
Inventor: HONEGGER WERNER
IPC: G06Q10/10
Filed: 1996-01-23
Abstract: With the inventive method a predetermined sequence of printed products with varying contents and varying numbers of pages is produced by printing the pages of a printed product of the sequence onto both sides of a quasi endless paper web (P) in form of at least one row of juxtaposed printed pages, that the pages of the next printed product in the sequence are then printed in the same manner, that the paper web (P) is folded perpendicular to its length in alternating direction between the pages to be printed or the printed pages, before or after the printing of the pages and that the paper web is then separated or brought into an easily separable condition perpendicular to its length between groups of printed pages forming one printed product. Thus a sequence of Leporello-shaped printed products (5) is produced which might be further processed into different shaped products. By mixing the data specific to the type of the printed product to be produced with data specific tothe individual specimen of the printed product, the contents of the printed products of the sequence to be produced can be individualized to choice.

Title: Method and package design for cryopreservation and storage of cultured tissue equivalents
Inventor: WATSON STEPHEN R
IPC: A01N1/02
Filed: 1996-01-30
Abstract: This invention is directed to an efficient cryopreservation package desgin of harvested mammalian tissues and living cultured tissue equivalents made by in vitro technology. The invention involves immersing a mammalian tissue or cultured tissue equivalent in a cryoprotectant solution, agitating the cryoprotectant solution and the immersed tissue to achieve effective penetration of the cryoprotectant solution into the tissue, and then freezing the tissue at a very slow freezing rate. In the freezing step, extracellular ice formation is initiated by seeding. The cryopreserved tissue may be stored for indefinite periods of time prior to use. The cultured tissue equivalent is an in vitro model of the equivalent human tissue, such as skin or cornea, which, when retrieved from storage can be used for transplantation or implantation in vivo or for screening compounds in vitro.

Title: Calcium carbonate precipitation method
Inventor: RAMSAY JAMES IAN
IPC: C01F11/18
Filed: 1996-03-01
Abstract: A method for producing precipitated calcium carbonate by reacting an aqueous solution of calcium nitrate [Ca(NO3)2] with an aqueous solution of ammonium carbonate [(NH4)2CO3] and allowing calcium carbonate to precipitate from the resultant mixture containing nitrate [NH4NO3] in the mother liquor, the process being characterised in that: (i) the calcium nitrate [Ca(NO3)2)]  solution utilised in the processes is prepared by slaking lime [CaO] in water in the presence of ammonium nitrate [NH4NO3] to form calcium nitrate [Ca(NO3)2] and ammonium hydroxide [NH4OH] in solution, filtering the solution to render it solids free, and heating the filtrate to dissociate the ammonium hydroxide [NH4OH] and to drive ammonia gas [NH3] from the solution; (ii) the ammonium carbonate (NH4)2CO3 solution utilised is prepared by absorbing ammonia gas [NH3] and carbon dioxide gas [CO2] in water, the ammonia gas preferably being derived from the step in (i) above in which the Ca(NO3)2 solution is heated; and (iii) the ammonium nitrate used is derived from the precipitation phase during which calcium carbonate is precipitated from the mother liquor containing ammonium nitrate.

Abstract: A reinforced pallet (20) and method for making the same are disclosed. The pallet (20) includes a body (28) having a pair of laterally spaced apart edge portions (56) with a central span (60) extending therebetween. A flexible tensile member (26) extends between the edge portions (56) and generally beneath the central span (60). The tensile member (26) may be in the form of a mesh affixed between upper and lower decks (22, 24) of the pallet (20). When the edge portions (56) of the pallet (20) are simply supported and a load is placed atop the pallet (20), the central span (60) of the pallet (20) will vertically deflect in response to the load. The central span (60) will bear upon the tensile member (26) with the tensile member providing support against deflection. A method for retrofitting a pallet (200) includes adding a tensile member (210) to the pallet (200) to reduce the amount of deflection of the pallet (200) when simply supported in response to a load placed atop the pallet (200).
