Patent NL-7613665-A (NL)
IPC: A61K35/14
Filed: 1976-12-08
Abstract: 1532848 Purifying proteins P G S LINDROOS 19 Nov 1976 [11 Dec 1975] 48376/76 Heading C3H  A method for separating iron compounds from the protein in a hemoglobin solution, comprises adding to said solution an organic solvent comprising ethanol in an amount such that the total ethanol content in the solution is at least 40% by volume, adjusting the pH of the liquid to a value lower than 4À5, whereby iron compounds in the solution are agglomerated, and thereafter separating the agglomerated iron compounds from the solution. The solution may be adjusted to a pH value which is less than 4À5 but greater than 2À5. Preferably the pH-value of the solution after agglomeration of the iron compounds is, before or after their separation, raised and wherein any fraction of blood protein precipitated thereby, with iron compounds included therein or adsorbed thereonto, is separated from the mixture. Before or after the agglomeration of iron compounds a minor quantity of broth of blood cells may be added to the solution and any flaky material of fragments of cell membrane formed thereby, together with iron compounds adsorbed thereonto, is then separated from the mixture. The organic solvent preferably includes a minor proportion of glycerin or ethylene glycol or methanol or acetone or ethylacetate or propanol or isopropanol or butanol. The iron compounds may be separated from the solution by centrifuging or a cyclone process or filtering or ultrafiltering or sedimenting or adsorption on to  voluminous or solid material, and the protein may be recovered from the solution by precipitation or adsorption on to solid or voluminous material or ultrafiltering or evaporation of the solution or drying or concentration of the solution by means of freezing.  The ethanol content in the solution after the agglomeration of iron compounds may be increased before or after their isolation and the fraction of blood protein precipitated thereby, together with any iron compounds included therein or adsorbed thereonto, may then be separated from the mixture. Before addition of ethanol to the solution and lowering of the pH of the solution, the solution is preferably cooled to a temperature of between zero and -20‹ C. and wherein this temperature is maintained during the entire further treatment.

Title: Appts. for circulating gas through tubes during heat treatment - partic. for removing carbon from long copper tubes wound into rings
IPC: C21D9/08
Filed: 1977-08-12
Abstract: Appts. is for circulating a sweeping gas through tubes wound into rings, partic. very long metal tubes, during thermal treatment in a furnace through which they pass. The appts. incorporates a series of hollow metal frames, fitted with nozzles to which one end of each ring can be connected. There are means for connecting the frames to one another and for feeding and discharging the sweeping gas. The frames so connected form a continuous train circulating in the furnace. The invention solves the problems incurred in reheating tubes of small dia. and in lengths of tens or hundreds of metres, partic. acute in reheating copper water tubes for use in dwellings and industrial installations. The lubricants used in drawing the tube adhere firmly to the tubes, during reheating at 500-600 degrees C, the lubricant undergoes pyrolysis and the residual carbonaceous material can cause pitting in the presence of water. The amt. of this residual carbon is reduced.

Filed: 1990-04-03
Abstract: In the firing chamber (1) of the combustion installation, there is arranged a firing grate (2) divided into grate zones (I, II, III) formed with rows of grate bars (10). The rows of grate bars (10) of the first grate zone (I) have no air outlet into the firing chamber (1). The primary air (15) brought in under these rows of grate bars (10) by guide plates (17) serves to cool the rows of grate bars (10) and is then guided by guide plates (18) into a connecting duct (19), by means of which the heated primary air (15) can be supplied to the following grate zones (II, III etc.). It is thus made possible to avoid a concentration of the burning off of unit waste with above- average calorific value in the region of the first grate zone (I). At the same time, uniform burning off is thus achieved over the entire grate surface. <IMAGE>
