Patent DE-3323446-A1 (DE)
Inventor: BAEHRING MANFRED DIPL ING
IPC: H03K3/353
Filed: 1983-06-29
Abstract: An input signal level converter for applying a TTL signal to an actual input of an MOS circuit is required for n-MOS digital circuits controlled with TTL signals. This circuit forms a Schmitt trigger and comprises five MOS field effect transistors and a bootstrap capacitor. The transistors are preferably of the n-channel type and are self-inhibiting. This circuit is improved by means of two further transistors connected such that a quiescent current consumption of the level converter is considerably reduced. Favorable dynamic behavior is achieved without having unfavorable current usage.

Title: Process for substantially removing unwanted metal ions, in particular vanadium ions, when concentrating dilute iron(II) sulphate-containing sulphuric acid solutions
Inventor: KULLING ACHIM DR
IPC: C01G23/053
Filed: 1983-08-18
Abstract: The sulphuric acid solutions are boiled down by evaporating water and by separating off iron(II) sulphate to a content of 60 to 70% by weight of H2SO4. According to the invention, as the sulphuric acid solution is boiled down, the use of trivalent titanium ensures that the content of trivalent iron in the sulphuric acid solution does not exceed 0.1 g/l. The trivalent titanium, if it is not already present in sufficient quantity in the solution, can be added from outside or can be formed from quadrivalent titanium already present in the solution by the addition of a reducing agent. Prior to the final concentration step, pre-concentrating and cooling of the pre-concentrated sulphuric acid solution can be employed to deposit and to separate part of the iron as iron(II) sulphate heptahydrate.

Title: Pressure medium-operated brake circuit for a plurality of axles of a vehicle or a vehicle combination
Inventor: PETERSEN ERWIN DR ING
IPC: B60T8/17
Filed: 1984-05-23
Abstract: In a brake circuit with pressure medium-operated brakes of two axle groups (4, 6), of which the second axle group (II) is not dynamically balanced in relation to the first axle group (I), with a load-dependent brake pressure governor (2) preconnected to the brakes, it is proposed to arrange a controllable valve device (5) (for example relay valve, double shutoff valve, load/no-load valve) between the brakes (4) of the first axle group (I) and the brakes (6) of the second axle group (II) and to trigger this device by way of a control valve (8) supplied from the uncontrolled brake pressure (p1) and controllable as a function of the brake force requirement predetermined by way of the braking power transducer (1). The load-dependent brake pressure governor (2) is here controlled only as a function of the load state of the first axle group (I). A variation of the brake pressure (p3) fed to the brakes (6) of the second axle group (II) compared to the brake pressure (p2) fed to the brakes (4) of the first axle group (I) is thereby obtained, which is adjusted not only according to the load but also to the dynamic variation in the utilisation of the available coefficient of friction by the axles (fig. 1). <IMAGE>

Title: Drive for a strip winder
Inventor: HOPPMANN HANS DIETER DIPL ING
IPC: B21C47/02
Filed: 1984-05-24
Abstract: The invention relates to a drive for a strip winder, especially a hot-strip winder with an expandable winding mandrel for winding the strip to form a coil at the end of the rolling or processing line. Known winder drives have high flywheel moments which lead to inadmissible variations of the rolling stock when the drive is being braked during the expansion of the winding mandrel. The object of the invention is, therefore, to provide a drive, in which the flywheel mass, related to the winding mandrel, of all the drive parts is kept as low as possible. To achieve this object, the drive is designed as a direct drive and consists of an electric motor (1) of low flywheel moment which is arranged coaxially relative to the winding mandrel and which is coupled (3) to the latter. <IMAGE>

Title: Process and apparatus for bubble-free introduction of gas into liquids, in particular culture media for growing tissue cultures
Inventor: LEHMANN JUERGEN DR ING
IPC: B01F3/04
Filed: 1984-08-22
Abstract: In a process and an apparatus for bubble-free introduction of gas into liquids, in particular culture media for growing tissue cultures, in which gas exchange takes place via an immersed membrane surface, a simple and effective and maximally uniform dispersion of the gas introduced and the gas desorbed is achieved without mechanical damage to liquid constituents by flexibly suspending, and subjecting to a circular pendulum movement without itself rotating, a tubular membrane basket which is formed of membrane hollow fibres in the medium into which gas is to be introduced. The rate of gas introduction is controlled by altering the frequency of the circular pendulum movement and/or the radius of the circular path or, alternatively, by altering the gas concentration in the gas flowing into the membrane basket.
