Abstract: The invention relates to a sintered transformer core of MnZn-ferrite material, the initial permeability of which ranges between 10 and 1000. Said transformer cores preferably have an average particle size which ranges between 0.05 and 2.0 µm.

Abstract: The invention provides a process for the production of 3-(1-amino-1,3-dicarboxy-3-hydroxy-but-4-yl) indole and certain salts and internal condensation products thereof. An unsaturated indolyl ester is reacted with ethylchloro(hydroxyimino)acetate in the presence of triethylamine in an organic solvent to cause a 1,3- dipolar addition reaction to form a di-ester. The di-ester is saponified to form a di-acid which di-acid is then reduced to form either the product indole or a salt thereof.

Abstract: A centrifugal pump comprises a casing and a rotary impeller (1) provided with a cover plate (8) and a plurality of spacing blade means (2) fastened thereto. Radially seen, each spacing blade means comprises an outer, solid section (2b′, 2b o ) and an inner section having at least one cavity (16, 17). The outer section forms an integral part with the inner section or is joined therewith. As a result the impeller is easily adapted to the desired operating conditions (capacity, pressure) without affecting the flow conditions at the outer periphery of the impeller, because a slight adaptation of the spacing blade means diameter by turning only results in removing material from the outer, solid section but not from the hollow section. The latter remains undamaged, and the flow conditions are consequently excellent.

Abstract: The invention relates to a method for determining the speed of a vehicle with slip-controlled wheels, which permits a continuous control of the slip of the wheels of a braked or driven vehicle and thus ensures the optimum utilisation of a wheel/carriageway coefficient of adhesion which is insufficient in itself. In this method, cyclically successive process steps are executed:   1. In each case a first wheel acceleration is determined from the measured speeds of the wheels including damping. 2. In each case a second acceleration is formed from this first acceleration in that only that portion of the latter is used which fulfils the condition that a positive or a negative limit value of a change in acceleration with respect to a value of a vehicle acceleration which precedes it in time is not exceeded. 3. An assumed vehicle acceleration is determined from the second acceleration values of all the wheels by forming averages. 4. A value for an assumed vehicle speed is generated by integration of the assumed vehicle acceleration. 5. By evaluating the measured wheel speeds it is determined whether the latter follow the tendencies of the assumed vehicle speed or acceleration and when required corrections of the assumed values are initiated.   <IMAGE>

Both control cross-sections are defined by approximately conical housing walls (10, 12) and/or approximately conical control elements (5, 6), the taper angle on the two control cross-sections being matched to one another such that, in the case of joint adjustment of the two control cross-sections, the quantities of gas and air admitted produce a predetermined mixing ratio for each adjustment position of the two control elements. The two control cross-sections are arranged in the housing and aligned with one another such that the controlled flows of gas and air emerging from them meet for mixing at the shortest possible distance from the outlet side of both control cross-sections. <IMAGE>

Abstract: The invention relates to a heat accumulator as a storage buffer for room heating. By means of the arrangement of a forward-run pipe (23) and a return-run pipe (26) with flowthrough openings in the upper region of a storage buffer container (2), energy storage becomes possible.
