Abstract: An iron-dextran compound for parenteral treatment of iron-deficiency anemia comprises hydrogenated dextran having a weight average molecular weight (Mw) between 700 and 1,400 Daltons, preferably approximately 1,000 Daltons, a number average molecular weight (Mn) of 400 to 1,400 Daltons and wherein 90 % by weight of the dextran has molecular weights less than 2,700 Daltons and the Mw of the 10 % by weight fraction of the dextran having the highest molecular weights is below 3,200 Daltons, said hydrogenated dextran having been subjected to purification by membrane processes having a cut-off value between 340 and 800 Daltons, in stable association with ferric oxyhydroxide. The compound is produced by using membrane processes to eliminate dextrans of higher molecular weights than approximately 2,700 Daltons and membrane processes to remove saccharides of molecular weights below approximately 340 Daltons from hydrogenated dextran before precipitating ferric hydroxide in the presence of said dextran followed by heat treatment and purification.

Title: Improved aqueous cleaning solution and method for removing uncured adhesive residues
Inventor: CALA FRANK
IPC: C11D3/26
Filed: 1999-04-28
Abstract: An alkaline, aqueous cleaning solution which is capable of removing at least a substantial portion of uncured adhesive residues, e.g., epoxy-based adhesives, from a substrate, preferably a metal stencil substrate, contains water, an alkalinity-providing agent and a synergistic combination of surfactants, specifically an N-alkylpyrrolidone surfactant, which is preferably N-octyl-2-pyrrolidone, and an aminocarboxylic acid surfactant, which is preferably N-coco-beta-aminopropionic acid. At an active-concentration ratio of the N-alkyl-2-pyrrolidone surfactant to the aminocarboxylic acid surfactant of from about 1:1 to about 3.5:1 and a total active concentration of at least 0.30 % by weight of the aqueous cleaning solution, the N-alkyl-2-pyrrolidone and aminocarboxylic acid surfactants synergistically improve the ability of the solution to remove uncured adhesive residues from the substrate, even at relatively low wash temperatures, e.g., from about 70 °F to less than about 135 °F.

Title: Method for controlling data transmission in a wireless v.24 data transmission system operating between a data terminal and a data transmission device for data telecommunication
Inventor: BIEDERMANN ROLF
IPC: H04M11/06
Filed: 1999-08-04
Abstract: The invention relates to a wireless V.24 data transmission system operating between a data terminal and a data transmission device for data telecommunication having a first data transmission apparatus connected to the data terminal by means of a V.24 cable and a second data transmission apparatus connected to the data terminal by means of a V.24 cable, wherein said apparatus may in turn be connected for wireless communication by means of an air interface. According to the invention, in order to control transmission of control commands or control information for the data transmission device from the data terminal to the data transmission device in such a way that recognizability of control commands or control information for the data transmission device is ensured, once advertising of the time critical control commands, e.g. the ESCAPE sequence, has been effected in the data transmission apparatus, the time sequence of the transmission of the control commands on the transmission path between the second data transmission apparatus and the data transmission device is identically reconstructed in the wireless V.24 data transmission system after transmission has been completed on the transmission path between the first data transmission apparatus and the data transmission device despite asynchronous data transmission caused by the air interface by observing the time information contained in the control commands (e.g. the pause time contained in the ESCAPE sequence).
