IPC: B23Q7/10
Filed: 1975-11-24
Abstract: The system is for a production line with a continuous or indexing conveyor and having two or more processing stations, each with its independent drive.

Title: Isolating embryo-foetal and tumour antigens from tissues - by immunochemical reaction with antisera against normal adult cell components only
Inventor: THEURER KARL DR MED
IPC: C07K16/30
Filed: 1976-04-02
Abstract: Isolation comprises immunological sepn. of a homogenate or lysate, or of a suspension or soln. of the dry powder, of such cells, by antibody-antigen reaction with immunoglobulins (I). Fractions which have not reacted with (I) are sepd. by centrifuging, chromatography or electrophoresis. The antigen soln. to be processed, and that used to make (I), are pref. made by controlled chemical decompsn. of the biological tissue. Thus the powdered tissue is decomposed in a sealed reactor with a reagent of b.pt. at atmos. pressure normal temp., under such a vacuum that the reagent can transfer to the vapour phase. When the required decompsn. has been achieved, unused reagent is removed. The gaseous reagent is first deposited on the substrate by reducing the vacuum and, then after reaction, excess reagent is removed by increasing the vacuum. (I) are obtd. conventionally by immunising hosts with adult or juvenile tissue contg. no EF antigen. Tumour cells give a mixt. of EF and T antigens and the former are removed by repeating the process with EF-specific antibodies. The antigens are used to make antisera for prophylactic or therapeutic treatment of malignancies withour risking immunological disorders (by reaction with normal adult or juvenile antibodies).

Patent DE-2656177-A1 (DE)
Inventor: GEHRER EUGEN
IPC: H05B41/04
Filed: 1976-12-10
Abstract: A thyristor (4) is connected between the connections for the fluorescent tube. When the thyristor is conducting, a heating current flows through the electrode of the fluorescent tube, and starting signals are produced when the thyristor is switched off. In order that the disadvantage of continuous displacement of the thyristor triggering time can be avoided, a control electrode of the thyristor is connected via a switching element (15) to the pick-off of a resistive voltage divider (7, 8), which is connected in parallel with the thyristor, in order to supply a voltage, which is proportional to and in phase with the voltage between the said connections, at the voltage divider pick-off when the thyristor is not conducting. Connected to the control path of the thyristor (4) is a second thyristor (10) which is connected to a first control signal source (11, 12, 13, 14), which results in a number of identical starting attempts being terminated after a fixedly defined number of such attempts. The control path of the second thyristor (10) is also connected to a second signal source (20, 21), as a result of which the starting attempts can finally be divided into individual series of attempts, which are terminated after a specific number of series. The starting network in each case reaches its optimum starting conditions again with respect to its thermal behaviour during the interruptions between the individual series of attempts. <IMAGE>
