Abstract: O-Carbamoyl derivatives of desferrioxamine B of the formula I <IMAGE> in which at least one of the radicals A<1>, A<2> and A<3> is a carbamoyl radical of the part-formula -CO-NH-Alk-CO-O-R<1>a (II), in which R<1>a is C1-C4-alkyl or C2-C4-alkenyl and Alk is C1-C7-alkylene which is unsubstituted or substituted by hydroxyl, C1-C4-alkanoyloxy, amino, C1-C4-alkoxycarbonyl, carbamoyl, phenyl, hydroxyphenyl, methoxyphenyl or indolyl, and the other symbols A<1>, A<2> and A<3> are, independently of one another, hydrogen or an acyl radical Ac derived from a carboxylic acid, and B is hydrogen or an acyl radical Ac which is different from alkyl-O-(CH2-CH2-O-)qCO-, in which q is a number larger than 5. These compounds form strong iron(III) and aluminium complexes inside living cells. They can therefore be used for treating pathological states in warm-blooded animals, including humans, which are associated with an excess of iron(III) or aluminium in the body or are caused by iron(III)-dependent pathogenic organisms. The compounds of the formula I can be obtained, for example, by conventional reaction of N-substituted desferrioxamine B with an isocyanatoalkanoic ester.

Abstract: An electroplating apparatus for rapidly depositing a metal onto a selected surface of a workpiece, which apparatus comprises an anode having an active surface with a selected shape to combine with the selected surface of the workpiece to define an elongated gap of at least about 0.050 inches, means for supporting this anode in a fixed position to define the elongated gap; solution circulating means for forcing an electroplating solution with metal cations through the gap in a generally closed path at a velocity to exchange electroplating solution in the gap at a rate of at least 25 times per minute; and, means for applying current flow between the selected workpiece surface and the active surface of the anode through the gap at a current density in excess of 2.0 amperes/in2. The invention also involves the method of using this apparatus to rapidly deposit metal, such as nickel, onto the inner cylindrical surface of a bore on a complex part such as an aircraft landing gear forging.

Abstract: A stationary gasifier (17) is located at a distance (49) from an air aperture plate (35). At the outlet (42) of the gasifier there is a stationary mixing head (29) having a deflector section (31) and lateral outlets (33). Fuel is supplied coaxially through an opening (55) of the air aperture plate. A flame tube (21) surrounds the gasifier (17) and an electric heater (39) leaving an annular space (40). When the burner is started up, the electric heater (39) is switched on until the gasifier has the necessary operating temperature. Fuel is then supplied. The fuel/air mixture is ignited by an electrode (65). The flame tube (21) extends to the end of the mixing head (29), or only a little therebeyond. A flame is formed at the outlets (33) that touches the flame tube after a short travel, then emerges from it and expands. Because the flame can immediately expand, only little NOx is formed. A portion of the hot combustion gases is recirculated through the annular space (40) and sucked into the gasifier to heat the gasifier (17) after the shutoff of the electric heater (39).

Abstract: A circuit arrangement for approximating a non-linear transfer function, particularly a logarithmic or antilogarithmic transfer function, is improved in such a manner that it obtains a much better temperature stability of its transfer characteristic. At the same time, analog/digital conversion or digital/analog conversion becomes possible. In this arrangement, the said converters are supplied with an analog reference quantity (Vref) and an analog (Vin) or digital/binary input signal (Win). The converters (20, 30) output a digital or analog output signal (Wout, Vout) on the basis of an essentially linear converter characteristic and a non-constant reference quantity (Vref) depending on the analog input or output signal (Vin, Vout) is input to the respective linear converter (20, 30). Furthermore, a method is shown, particularly for operating the aforementioned circuit arrangement and a lighting system using the aforementioned circuit arrangement. In the lighting system, the brightness of one or more light generators is changed to suit the eye. <IMAGE>

Abstract: A support for integrated circuits or semiconductor chips consisting of a support substrate in the form of a flexible film (2) having on its surface contact areas (4), conductive tracks and terminals (6) for the semiconductor chip (7) is fitted with a stiffening ring (8) surrounding only a part of the surface of the substrate (2). The material of the stiffening ring is such that its flexural strength is substantially higher than that of the flexible substrate (2). The integrated circuit/s is/are arranged inside the stiffening ring (8) in the form of a semiconductor crystal (7). For the further protection of the semiconductor chip, the inside of the stiffening ring is filled with a potting compound. The fact that the stiffening ring has securing projections (9) pointing radially inwards and substantially uniformly distributed over the inner circumference of the reinforcing ring reduces the danger of the compound separating from the stiffening ring.

Abstract: The method concerns production of finish castings with use of aluminium alloys with 0.15-1.0 % iron and other impurities as the starting material. This material is cast into a blank with fine-grained structure. The blank is then subjected to heat treatment at temperature close to the solidus point for purposes of growing and rounding its grains. Finally, the blank thus heated is liquefied under pressure and cast to produce a finish casting. The grain size of the blank material varies from 0.02 to 0.3 mm, and pref. from 0.03 to 0.15 mm. During heat treatment of the blank, which takes place inductively, the grain growth varies from a minimum of 20% to a maximum of 70%. The pressure is applied in the filling chamber of a high-pressure die-casting machine by means of a piston.
