Abstract: A multiple blood bag system comprising a donor bag for receiving blood from a donor, and one or more transfer bags, communicating by flexible tubing with the donor bag, for receiving a blood component from the donor bag. In accordance with this invention, the various bags may be made of differing materials to provide differing characteristics to the bags as desired. For example, the transfer bag or bags may be made of a translucent, flexible, sterilizable material which is free of blood extractable ester-type plasticizers, and may have a relatively high carbon dioxide diffusion capacity. The donor bag may be made of a translucent, flexible, sterilizable material which contains preferably at least five percent by weight of a specified ester plasticizer, sufficient to cause a substantial reduction in plasma hemoglobin produced by blood stored under normal conditions for 21 days in the donor bag, when compared with blood in a corresponding, plasticizer-free donor bag stored under equivalent conditions.

Abstract: For the movement of bar stock (6) within a limited area, overhead cranes or bridge cranes equipped with elongated, horizontally manoeuvred lifting yoke (1), are used to advantage. The load can be comprised of single bars or bundles of bars. According to the invention, the lifting yoke (1) has a number of hydraulically manoeuvrable pairs of claws (12) placed at a distance between each other and designed to grip around the load. Through this the need for padding under the material or between the each of the stacked bars or bundles is eliminated. In relation to the lifting magnets, this is also beneficial partly because non-magnetic and warm materials can be held fast, and partly because lifting occurs in a more secure manner.<IMAGE>

Abstract: Disclosed is a process for recovering chromium, vanadium, molybdenum, and tungsten from secondary resources such as alloy scrap comprising a refractory metal and base metals such as cobalt, nickel, iron, and copper. The scrap is calcined with sodium carbonate in air to convert the refractory metal values to MoO4=, VO4=, WO4=, and CrO4= and the base metals to water insoluble oxides. A leach of the calcined materials produces a pregnant liquor rich in refractory metals which, after separation of the vanadium, molybdenum and tungsten values, is treated with CO, CHOO-CH3OH, or HCHO to reduce Cr+6 to CR+3. The carbonate and bicarbonate salts produced as a byproduct of the reduction are recycled to the calcination stage. As a result of the V, W, and Mo partition, a mixed solid comprising CaO.nV2O5, CaMoO4, and CaWO4 is produced. This is treated with carbonated water or formic acid to selectively dissolve vanadium values which are subsequently recovered by precipitation or extraction. The remaining mixed CaWO4 and CaMoO4 solid is treated with H2O2 and sulfuric acid to reject a Mo and W-free CaSO4 precipitate, and to produce a concentrated solution of tungsten and molybdenum. The W values are selectively precipitated from this solution by decomposing the peroxy complexes. The process has the advantages that a wide variety of different feed materials can be treated, no energy intensive pyrometallurgy is involved, reagent comsumption is minimized, and no aqueous effluents are produced.

Abstract: The production of pig iron from mouldings which consist of lump ore or of fine ores containing iron and optional additives, even today requires the expenditure of very large amounts of energy, particularly if the mouldings have to be fired in order to have sufficient mechanical strength during the reduction process, for example in a reduction blast-furnace. In smelting processes with simultaneous production of a reduction gas in the smelting gasifier, cooling of the reduction gas generated to a temperature below the sticking temperature of the pellets can only be achieved by complex and expensive equipment and procedures. According to the invention, said drawbacks are overcome by the green mouldings (7) being preheated, dried and reduced to sponge iron on a travelling grid (8), using a process gas from a coal gasification reactor (17), making full use of the thermal energy contained in the process gas generated, and being then continuously fed, via a feed shaft (15) which can be sealed in a gas-tight manner, into a coal gasification reactor (17) and being smelted. <IMAGE>

Abstract: A description is given of an elastically flexible suspension arm joint which permits simplified installation and support as well as an advantageous design and arrangement of its bearing block on the axle or on the underbody. 
<??>The suspension arm joint can be supported on a bearing body by means of a rubber-elastic bush arranged in a bearing opening in a suspension arm-joint head, it being possible to clamp the bush between abutments by its ends, which project from the bearing opening, for the purpose of prestressing. For simplified installation and support, the bearing body forms a bearing shaft which can be clamped fast by its end pieces on the bearing block, onto which bearing shaft in each case one clamping plate forming an abutment can be pushed. Supported against the outer side of each clamping plate is at least one clamping element, which rests against an oblique surface and, when the bearing shaft is clamped fast to the bearing block, can be moved by a respective clamping bolt at least in the direction of the axis of the bolt. This movement of the clamping elements is converted by the oblique surfaces into a movement of the two clamping plates towards one another to prestress the bush.
