Abstract: A gas-injection lance (4) has a relatively flat outlet (5) and is positioned under a burner (44) so as to provide a relatively flat jet of gas under the flame (12). The effect is to flatten the flame (12) by creating a pressure induced deformation of the flame (12). The surface of melt (46) is thus heated more uniformally and the creation of hot spots on the surface can be prevented.

Abstract: A solid-phase support suitable for immunological assays is stained with an organic dye that has a net-positive charge and a hydrophobic aromatic ring structure. An immunologically reactive component having a net-negative charge is immobilized by the dye to the support through non-covalent interactions. The immunologically reactive component is tightly bound by the organic dye. This is advantageous when performing immunological assays utilizing automated washing instruments. A sample of a biological fluid is added to the article having the immunologically reactive component bound thereto to detect the presence of antigens or antibodies in the biological fluid specific for the bound immunological component. The presence of the antigen-antibody complex may be determined by any known method.

Abstract: A transceiver determines the signal quality of a desired signal and the strength of all received signals. When the signal quality of the desired signal is low, and the signal strength of all received signals is high, the receiver is adapted to operate in a higher current mode, thereby minimizing intermodulation distortion. Conversely, when the quality of the desired signal is low and the strength of all received signals is also low, or when the quality of the desired signal is above a threshold, the receiver operates in a lower current mode to conserve power and maximize battery lifetime. Also, when the transceiver adapts to operate in the higher current mode, a command is sent instructing a transmitting party to increase the quality of their message which may enable the listening transceiver to adapt (return) to a lower current mode.

Abstract: The present invention concerns a procedure for bleaching cellulose pulp obtained from hardwood, wherein bleaching chemical containing chlorine is used. The essential feature of the invention is that the residual chlorine content of the bleached pulp is reduced by subjecting the pulp to enzyme treatment. With the enzyme especially the removal from the pulp of chlorine-binding extractive substances present in hardwood pulp is promoted. The invention furthermore concerns the use of enzyme towards lowering the residual chlorine content of bleached cellulose pulp made from hardwood. Such cellulose pulp is particularly contemplated which will be converted into foodstuff package cardboard or paper, which are commonly disposed of by burning. Lowered chlorine content reduces the risk of producing toxic dioxin at the incineration step.
