Pt ions applied to the surface from soln.; (b) (IIA) is dried and reduced with H2 before use; (c) (IIA) is placed in the HCN reactor, which is heated to 1000-1350 deg.C and charged with the usual mixt. of NH3 and (I) for this reaction, which is initiated by (IIA); and (d) after a short time, reaction is continued with the Al nitride film formed in situ on the surface of (IIA). Pref. (I) is CH4. (II) is a pref. tubular moulding prepd. from alpha-alumina by impregnation with H2PtCl6 soln. (pref. contg. 0.5-5 wt.% Pt ions) and an AlCl3, Al(NO3)3 or Al2(SO4)3 soln., pref. using a noble metal (Pt):Al molar ratio of 0.001-0.1:1, esp. 0.01-0.1:1.

Abstract: A fixed sensor for supplying a control signal corresponding to a rotation of the rotor of a dc motor is used in a commutation to an actual control value which is prolonged by a further time duration after which commutation for one  path is started. The proportionality factor for optimum commutation can be ed during motor operation according to acceleration, braking and change of direction of rotation. A microprocessor is used to control this adjustment. The start of commutation of the following windings is initiated at the end of the second time duration by cascading further durations proportional to the actual control value, also controlled by a microprocessor.

Abstract: The invention relates to an apparatus for initial charging of the output capacitors of a three-phase three-point pulsed rectifier system. According to the invention, a thyristor is arranged in each phase between the input terminal and is connected in the current flow direction to the anode of the freewheeling diode, and an initial charging path is connected in parallel with this thyristor. The circuit for actuating the thyristor is activated after completion of the initial charging; the reference voltage is applied to the negative input of the comparator. When the potential profile which is present at the tap of the voltage divider at the input of the bridge path rises, the voltage at the positive comparator input slightly before the zero crossing of the mains voltage to positive values exceeds the reference voltage, thus initiating switching of the comparator output and/or actuation of the thyristor and, after the mean bridge branch input potential passes through zero, the actuation of the thyristor is suppressed once again. The thyristor is thus triggered only within that mains voltage half-cycle in which it is required for carrying the mains phase current.
