Abstract: ABSTRACT         An improved process for the preparation of 2,3,4,5-tetrafluorobenzoic acid is described which involves decarboxylation of tetrafluorophthalic acid in the presence of a base catalyst.  Also described is an improved method for preparing tetrafluorophthalic acid and, in turn, a one-pot process for tetrafluorobenzoic acid using the combination of the two improvements.  These compounds are intermediates for the preparation of 1-cyclopropyl-6,7,8-trifluoro-1,4-oxo-3-quinoline carboxylic acid which is a key intermediate for the preparation of 7-aminosubstituted-1-cyclopropyl-6,8-difluoro-4-oxo-quinolines which are antibacterial agents.

Abstract: The invention relates to a process for producing steel of low phosphorus content from hot metal of usual phosphorus content, in which the hot metal is simultaneously decarburized and dephosphorized in a single process step in a metallurgical vessel, in particular in a converter. The refining gas consisting predominantly or completely of technically pure oxygen is top-blown into the melt, particularly from below. The vessel is charged with hot metal containing manganese in an amount of less than 0.2% by weight. Lime is then added and refining is carried out down to a final phosphorus content of 0.005% by weight or less in the steel at the end of blowing, without a change of slag.

Abstract: A one-step assay for the free portion of a ligand in a biological sample involves incubating a mixture of the sample with a labelled antibody for the ligand and a ligand analogue which competes with the ligand for binding to the antibody. The assay is characterized by using a monoclonal antibody and by choosing a ligand analogue which has a lower affinity for the antibody than does the ligand. An insolubilised ligand analogue preferably has a binding affinity for the antibody from 0.01% to 10% of that of the ligand. Ligand/ligand analogue pairs exemplified are T4/T3 (Thyroxine/Triiodothyronine); Testosterone/etiocholanol; and T3/T2.

Abstract: The invention concerns a method in the regulation of the headbox of a paper machine/board machine. In the method, an additional flow (Q3.1,Q3.2...Q3.n) is introduced into the pulp suspension at different points across the width of the headbox, the concentration of said additional flow (Q3.1,Q3.2...Q3.n) being regulated. The concentration of the additional flow is regulated by means of a mixer unit (22), which comprises a displaceable distributor part (26), whereby, when the mixing ratio is being regulated, the flow resistances of the component flows (Q1,Q2) entering into the mixer unit (22) are adjusted by displacing the distributor part (26,260) of the mixer unit (22) in the chamber (F) of the mixer unit (22). <IMAGE>

Abstract: The endless drive belt is produced by winding a pre-formed load-carrying member (6) comprising a cord (8) embedded in a solid but softenable elastic material (10) along and around a surface of an endless compression member belt (2) also comprising a solid but softenable elastic material, thereby forming a layer (4) comprising a plurality of turns, and by simultaneously causing said turns to become intimately bonded to said surface. Said bonding is achieved by applying mutual pressure between said turns and said surface during winding and by selectively softening the surface layers of both said load-carrying member and said endless compression member belt which are to come into contact with each other, just prior to coming into contact with each other. The material of said surface layers is allowed to fuse. Said turns of said load-carrying member are further allowed to be partially impressed in said surface of said endless compression member belt. Softening may be carried out by the application of heat and/or the application of an adhesive. A device for carrying out the above method is also disclosed. With the device disclosed endless drive belts may be easily produced in-house at the time they are required at any size and at minimal costs and capital outlay.

Abstract: Glass-fibre reinforced plastic tank, for example for liquid petroleum gas under high pressure, compressed air for air brakes or for storage of acetylene. The tank is composed of two halves (10, 12), the open ends of which are conically bevelled to form a male end (20) and a female end (22), which are joined to each other by an adhesive. The reinforcement in the outer and inner layers of the halves contains essentially longitudinal glass-fibre strands and the intermediate layer contains essentially transverse glass-fibre strands. In the half with the male end (20), the longitudinal glass-fibre strands in the inner layer (35) are densely located adjacent to each other, while the longitudinal glass-fibre strands in the outer layer lie in separate groups (30) of densely arranged glass-fibre strands with the predetermined spacing between the groups to form channel-shaped spaces (31). In the half with the female end (22), the order is reverse. In order to store acetylene, a pre-fabricated absorbent body of porous material is enclosed in the tank when the tank halves are glued together.
