Patent DE-2730959-A1 (DE)
Inventor: NADAS JULIUS
IPC: F16D65/28
Filed: 1977-07-08
Abstract: A piston (3) which can be subjected to compressed air via an air inlet (2) is mounted in axially displaceable fashion in a brake cylinder (1). As the force output member, the piston (3) carries a piston rod (4), the end of which is pivotably attached in the central area of a lever member (5) extending transversely to the piston rod. One end of the lever member (5) is pivotably attached, via a pin (6) to an output member (7). The friction elements of a friction brake are articulated on the end of the output member (7) which projects to the outside. Rotatably mounted on the other end of the lever member (5) is a rolling element (9) capable of rolling on a wedge surface (10) serving as a fixed abutment. The wedge surface (10) has a portion (11) with a relatively steep slope, which merges via a rounded salient (12) into a portion (13) with a less steep slope. When the piston (3) is moved downwards by the compressed air, the rolling element (11) first of all rolls along portion (11) and then along portion (13). The output member (7) thus pushes the friction elements of the brake rapidly into the position of contact and then more slowly but with greater force against the rotating element of the brake. <IMAGE>

Title: Four-pole cable plug - has space requirement reduced by insetting cable entrance hole by minimum bending radius of cable
Inventor: THOM GUENTER
IPC: H01R13/56
Filed: 1977-09-27
Abstract: The four-pole cable plug has the opening (7) for the cable in its end (8) set in away from the end by a distance equal to or greater than the minimum permissible bending radius of the cable (2). The hole is therefore roughly at the centre of the large face of the plug. The advantage of insetting the hole in this way lies in making the plug smaller both in its direction of insertion and at right angles to this direction.

Title: Forced commutation system for thyristor circuit - operates with mutually coupled inductors inserted into thyristor leads
Inventor: HARMOINEN MARTTI DIPL ING
IPC: H02M7/515
Filed: 1977-10-21
Abstract: The normally separate inductors in the main thyristor (Tp) leads and in the common lead to the commutating thyristors (Ta) are combined into two mutually coupled inductors (L1, L2). By means of this mutual coupling the effect of the separate inductor in the commutating thyristor connection is synthesised. The mutual coupling can be adjusted to the desired value for correct commutation by altering the size, and for fine setting the spacing between, the two inductor coils (L1, L2). This form of construction reduces the bulk of the whole assembly and makes possible the manufacture of small compact inverters.
