Patent DE-3116600-A1 (DE)
Title: Engine mounting arrangement
Inventor: KAKIMOTO TOSHIHIKO
IPC: F16F13/10
Filed: 1981-04-27
Abstract: An engine mounting arrangement has elastomer mounting blocks, which are arranged between laterally extending arms connected to the engine and a cross member of the chassis close to supports fixed to its outer ends. In the event of a rolling motion of the engine, the blocks can be subjected to a shearing action about an axis essentially extending in a longitudinal direction. The arrangement also has a mounting unit with an elastomer part defining a chamber, which part can be freely subjected to a shearing action without varying the volume of the chamber defined by this when the engine rolls, but which experiences a variation of the volume when the engine pitches or oscillates in the vertical direction. Due to the variation of the volume a working fluid is pumped from the chamber through a flow limiter into a second chamber of variable volume so that a vertical movement of the engine is heavily damped, whereas rolling is permitted without restriction. By means of the arrangement, the transmission of oscillations from the engine to the chassis, and the tendency of the cross member itself to oscillate, are reduced to a minimum.

Title: Triggering circuit for series-connected thyristors
Inventor: VUKASOVIC LOVRO DIPL ING
IPC: H02M1/092
Filed: 1982-07-26
Abstract: In the triggering circuit according to the invention, a number of isolating transformers (U1-Un) corresponding to the number of thyristors (Th1-Thn) is provided. The primary winding of a first isolating transformer (U1) is connected to an alternating-voltage source (W) and the primary winding of each further isolating transformer (U2-Un) is connected to the secondary winding of a preceeding isolating transformer. Each secondary winding of the isolating transformers (U1-Un) is connected via a rectifier (B) to an energy reservoir (CB). Each energy reservoir, in turn, is connected via a light-controllable semi-conductor switch (T1-Tn) to the gate of an associated thyristor. In this arrangement, the triggering energy required for the thyristors (Th1-Thn) is provided by a separate alternating-voltage source (W) independently of the voltage present across these thryistors. The insulation voltage of the individual isolating transformers (U1-Un) must only be equal to the reverse voltage of a single thryristor (Th). The thyristors are triggered by optical fibres (L1-Ln) which are optically coupled to the light-controllable semiconductor switches (T1-Tn). <IMAGE>
