Abstract: A sheet of foldable material having a plurality of laterally spaced parallel fold lines dividing the sheet into consecutive panels to allow for folding of the panels into overlapping engagement. A notched edge protecting section comprising at least two panels folded into an overlapping engagement and formed from the removal of material from the overlapping panels. An un-notched edge protecting section comprising at least two panels folded into an overlapping engagement and including a first and second leg each having an inner longitudinal edge, outer longitudinal edge and an outside edge wherein the angle between said first longitudinal edge and said outside edge is greater than 90 degrees. A third and a fourth leg formed from the folding of said un-notched edge protecting section so that at least a portion of the inner longitudinal edges of the first and second legs contact one another.

Abstract: A blank sheet of foldable material having a plurality of laterally spaced parallel fold lines dividing the sheet into six consecutive panels to allow for folding of the panels into overlapping engagement. A first leg formed from overlapping panels two, three and six. A second leg intersecting the first leg formed from overlapping panels one, four, and five. An adhesive placed between panels two and three, panels one and four, panels one and five, and panels two and six for securing the panels together to maintain the legs in a fixed folded arrangement with each other.

Abstract: A blank sheet of foldable material having a plurality of laterally spaced parallel fold lines dividing the sheet into five consecutive panels to allow for folding of the panels into overlapping engagement. A first leg formed from folding panels two and three so that the top side of panel two is placed in face-to-face contact with the top side of panel three. A second leg intersecting the first leg formed from folding panels one, four, and five so that the top side of panel one is placed in face-to-face contact with the top side of panel four, and the top side of panel five is placed in face-to-face contact with the bottom side of panel one. An adhesive placed between panels two and three, panels one and four, and panels one and five for securing the panels to maintain the legs in a fixed folded arrangement with each other.

Abstract: There is disclosed medical prostheses filled with an aqueous solution of polyethylene glycol. The aqueous solution can be a saline solution. There is also disclosed a method of making such medical prostheses. The novel prostheses are useful, for example, as breast implants.

Abstract: A process for preventing contamination of a reagent system by a reagent delivery system. The process is suitable for performing an iron determination of a sample which prevents iron contamination of the sample from metal or iron-containing surfaces contained within the apparatus used to perform the iron assay. The process comprises pretreatment of the reagent delivery system surfaces with a silane solution and then washing the pretreated surfaces with water to remove any excess silane solution. Generally, the silane solution is an organosilane solution which can be an emulsion.
