Patent DE-4041045-A1 (DE)
Inventor: MEYER THOMAS DIPL BIOL DR
IPC: C07K14/28
Filed: 1990-12-20
Abstract: The present invention relates to a genetic engineering process for the optimal production and exposure to the immune system of additional antigen coded for by a live vaccine. The genetic engineering process is based on the use of spontaneous DNA reorganisation in the recombinant live vaccine, such that the recombinant live vaccine spontaneously divides into two subpopulations (A and B), whereby subpopulation A is capable of infecting and acts immunogenically per se as a minimum characteristic and subpopulation B as a minimum characteristic is regenerated by subpopulation A, produces additional antigen and acts immunogenically with respect to said additional antigen. The formation of two subpopulations of the live vaccine ensures, on the one hand, that the infection process necessary for the induction of an immune response takes place and, on the other hand, that the formation of additional antigen by a hybrid live vaccine does not disturb the infection process in order to finally achieve an effective immune response to the additional antigen and the pathogen cross-reacting therewith.

Filed: 1991-01-19
Abstract: An enclosed chamber whose volume can be increased and decreased by means of a partition or piston moving from BDC to TDC and back, contains a quantity of volatile liquid at a base temp.

Title: Measuring thermal resistance and transient heat impedance of thyristors - detecting breakdown voltage produced by regulated measuring current as temp.-dependent electrical value at gate and auxiliary cathode terminals
Inventor: THAL ECKHARD
IPC: G01R31/26
Filed: 1991-02-08
Abstract: The thermal resistance and impedance values are measured w.r.t. a base point with derivation of the temperature coefficients and using the temperature dependence of an electrical characteristic value. A regulated measuring current (IM) is introduced in the reverse direction at the gate-cathode bridging path of the thyristor (GTO) to serve as the power pulse. The breakdown voltage (UEK) produced is directly detected at the gate and auxiliary cathode terminals (G,K') and evaluated by the temperature coefficients of the thyristor derived by means of calibration characteristic curves. A regulated current source (I), a switch (SE) and a voltage measurer (V) with a compensating voltage source (E) in series are placed in parallel with the gate and auxiliary cathode terminals. The switch and voltage measurer are coupled via a control (ST). The voltage measurer can be a storage oscilloscope. USE/ADVANTAGE - Especially suitable for GTO thyristors as separate components or rectifier units. Quality control during manufacture or diagnosis of rectifiers already working. Avoids faults arising from switch-over pause between load and measurement.
