    • 434,030. Current transformers. STEIN, G., 34, Tabbertstrasse, Obersch÷neweide, Berlin. March 9, 1934. Nos. 7490/34 and820/35. [Class 38 (ii)] Relates to a current transformer having two or more core sections in which to effect correction of phase angle and ratio errors premagnetization is effected by means of cross-connected windings nb, Fig. 4, supplied from the main secondary n. To effect ratio compensation the voltage applied to the premagnetizing windings nb is maintained constant by means of a parallel connected saturated choke nc. This choke winding may be mounted on a core, as shown, which links the primary circuit. To avoid error due to ohmic drop due to the secondary load current passing through the choke winding, the windings nb may be supplied from a winding inductively coupled with the choke winding. To enable phase angle correction to be effected a resistance R1, Fig. 7, and if desired a resistance R2 may be connected in parallel and series respectively with the windings nb. The resistance R2 may be a barretter type resistance. Phase control may also be effected by a choke connected in series with the main load L. The phase and ratio control may be combined in a single transformer to give combined correction. Further correction may be effected by varying the ratio of core cross-sections. An arrangement is described in which the ratio of cross-section is varied with the turns ratio. Fig. 13 shows an arrangement for obtaining finer correction, in which two auxiliary cores Se are provided, windings nd, and ne in series and parallel respectively with the load L linking these cores. One of these windings may be omitted if complete accuracy is not essential. In a further modification the winding nd is omitted and the winding ne is connected in parallel with the main secondary winding n. Specifications 286,431, [Class 38 (ii)], and 399,611 are referred to.

    • Spring-and-damper assembly articulated at a front hood and body of a motor vehicle and has, in a cylinder, a gas pressure damper with a damping piston, a piston rod outwardly loaded by the gaseous medium through an axial opening in the cylinder and assists opening of the front hood. An actuator activated by a sensor device to adjust the front hood into a raised pedestrian protection position. The piston rod or the cylinder or a structural component part is axially adjustable relative to a supporting part supporting the assembly to be limited between stops. The structural component part or supporting part is a ball head supported in a joint socket or a joint head having a joint socket for a ball head connected at least indirectly to the piston rod or to the cylinder. The joint socket is formed so as to be groove-shaped in axial direction so that the ball head is axially adjustable in the joint socket in a limited manner.

    • A gas spring with a center longitudinal axis including a cylinder includes a piston in the cylinder that divides the cylinder into a first cylinder chamber and a second cylinder chamber. A piston rod is arranged at the piston guided out of the cylinder at a second end opposite the first end. A connection element with a socket housing is arranged at each of the first end and the free end of the piston rod for receiving a ball head. At least one of the two socket housings comprises a ball socket with a longitudinal extension and a transverse dimension, the longitudinal extension is greater than the transverse dimension. A catch element having a spring tongue is arranged at the first end for insertion together with the catch element into a cover tube that locks into a recess associated with it in the cover tube.
