Abstract: A small DC motor which can be driven at a high rotating speed and a high efficiency, can be produced at a low price, and is of a type of three-phase star-connection. From a position sensor provided with three Hall elements which sense the rotational position of the rotor of the motor, first position signals of the first to third phases, each having a width of 120 degrees in electrical angle, and second position signals which are different from the first position signals in phase by 60 degrees are inputted to a control circuit. The control circuit, by forcing successively transistors (10a-10d, 11a-11h) in the transistor bridge circuits respectively associated with the armature coils (4a-4c) of the respective phases into conduction, supplies current to the armature coils of the respective phases in the forward and reverse directions. When stopping the current to the armature coils, by charging capacitors (16a-16c) connected to reverse blocking diodes (17a-17c) by use of the magnetic energies stored in the armature coils, the magnetic energies are decreased quickly. When starting the current application to the armature coils, by the charged voltages of the capacitors, the armature currents are made to build up rapidly.

Inventor: BINDER WOLFRAM DR
IPC: A23K1/16
Filed: 1992-09-09
Abstract: 2.1. Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at only a few percent. Drying the crude fermentation broth and using it as such generally led to aggregating sticky products or to products having too low a supplementary amino acid content. Using the new animal feed supplement and preparation process, a supplementary amino acid is intended to be made available which is not too expensive, not excessively hygroscopic or sticky, and whose contents can be standardised. 2.2. The animal feed supplement is based on a fermentation broth and contains the majority of its components, if required, with the exception of part of the biomass. Preferably, the biomass is present at no more than 10 % by weight of the dry matter. Proteins are preferably present at up to a maximum of 10 % by weight. For the production, during fermentation, at least towards the end, the sugar content is adjusted to a value of at most 4 g/l and during further processing, if required, at least a part of the biomass is separated off. 2.3. Supplementation or preparation of animal feed agents or premixes, in particular containing lysine.

Through a pump (10) connected in the conduit from the separator to the lower part of the transformer tank, the oil level of the collected oil is maintained at a constant level. Between the glass filter and the collected oil, a gas compartment (5) is formed which contains gases, extracted from the oil, with a composition and concentrations uniquely determined by those gases dissolved within the oil. A gas sensor (6) is connected between the upper and lower parts of this compartment.
