Title: Method for the quantitative determination of eleutherosides A, B1, B, D and E
Inventor: BAEVSKIJ ALEKSANDR VIKTOROVIC
IPC: G01N21/64
Filed: 1981-07-03
Abstract: The method for the quantitative determination of eleutherosides A, B1, B, D and E comprises adjusting the optical density in the mixture to be analysed to a value of 0.08-0.1 at wavelengths which are in the range from 270 to 380 nm. Spectra are then recorded, and the magnitudes of the luminescence intensity at the maximum of the luminescence on excitation at wavelengths in the same range are measured. The resulting magnitudes of the luminescence intensity are used to calculate the concentrations of the eleutherosides in two variants. The first comprises comparing the magnitude of the luminescence intensity of the mixture to be analysed with the magnitude of the luminescence intensity of the solutions of pure eleutherosides using the known ratio between the eleutherosides in the eleutherococcus, which is A:B1:B:D:E = 4:5:15:12:1. The second variant for determining the concentrations comprises calculation according to the formula <IMAGE> where C is the concentration of the eleutheroside or of the mixture of the eleutherosides, F is the magnitude of the luminescence intensity, n is the degree of dilution or evaporation of the mixture to be analysed when its optical density is adjusted to a value of from 0.08 to 0.1; <IMAGE> is a constant, where tg alpha  and tg alpha -standard are correspondingly the tangents of the angle of inclination of the linear sections of the plots of the dependence of the magnitudes of the luminescence intensity of the corresponding pure eleutheroside or of the mixture of pure eleutherosides B, D, E and of the standard substance on their concentration, where tryptophan is a standard substance for the determination of eleutherosides B, D, E, and 1-anilinonaphthalene-8-sulphonate is a standard substance for the determination of eleutheroside B1, which have been recorded under the same conditions. The concentration of eleutheroside A is calculated by using the value obtained for the concentration of eleutheroside B1 based on the known ratio between these eleutherosides in natural mixtures thereof. The invention has uses in the pharmaceutical industry in the production of eleutherococcus preparations, in pharmacology, in the foodstuffs industry and for detecting possible adulterations of eleutherococcus preparations.

Patent DE-3130501-A1 (DE)
Title: Control body arrangement for units with fluid flow
Inventor: EICKMANN KARL
IPC: F04B1/20
Filed: 1981-07-23
Abstract: The invention relates to a control body arrangement with the control body supported in a mounting so that it is displaceable in an axial direction and at least one contact pressure chamber behind a corresponding part of the control body for pressing the control surface of the control body on to the sealing surface of the rotor of a machine with a fluid flow through it, such as a pump or a motor, as are known, for example, from the German P 968539 or the US P 3850201. Whilst the arrangements thus disclosed have sometimes functioned for certain speeds and pressure ranges, the invention recognises that control body arrangements of this type have a tendency to twist in the direction of rotation and then to jam in their mounting under a wedging action, so that the arrangement can no longer fulfil its function of automatically pressing the control surface on to the sealing surface without local overheating of the surfaces and increased leakage between the said surfaces. Accordingly, the invention provides for the arrangement of a locking device to prevent twisting of the control body about its axis. This may also involve locating the centres of pressure of the relevant control zone and the relevant contact pressure chamber more precisely one behind the other and restricting the contact pressure to a minimum, since the investigations in accordance with the invention led to the finding that the twisting and subsequent jamming of the control body partially stems from the fact that the claimed uniformity of pressure points in reality, for example in the German P 968539, could not even exist. In an especially simple form the invention overcomes the tendency to jamming by increasing the accuracy of centres of pressure, for example in Fig. 6, which overcomes the deficiencies of the German P 968539. Should the improved design and location of the centres of pressure not be sufficient to prevent jamming of the control body, a mechanical locking device is arranged, for example in accordance with Fig. 27. In the description of the invention, precise and reliable teachings on the technical action are given, which prevent the tendency to jamming recognised by the invention. <IMAGE>
