In order to prevent betulinic acid from crystallizing in a galenic preparation containing water, a plane tree cream in the form of a stable emulsion containing oil and water is proposed, which is characterized by a content of 2 to 10% by weight of a plane tree extract obtained from the bark of plane trees, 0.1 to 9.9% by weight of glycerol, 0.1 to 1.9% by weight of a gelatinizing agent and 5 to 15% by weight of a preservative. The plane tree extract used is obtained by extracting plane tree bark with a low alkanol. The plane tree cream is used for the topical treatment of the skin, including the mucous membranes.

Formulations for dressing, dressing layers, dressed textile fibers and textile fabrics, and methods for dressing textile fibers and textile fabrics are provided. The textiles can receive, a plurality of times, active substances, or active ingredients, which can be deposited in a isotropic manner to the surrounding medium or in an anisotropic manner in a directly adjacent layer by means of a locally oriented material flow. The dressing layers are characterized by their ability to swell and to receive active substances. Polymer layers form nano pockets during swelling which can receive one or several guest molecules. The active substances can be deposited when the loaded textiles are worn and absorbed by the skin of the wearer, either cutaneously or percutaneously, to produce the desired effect.
摘要:
An inductive position sensor has a spatially periodic scale with a series of conducting or permeable features of pitch T and a reading head with drive windings and sense windings, facing the scale with a spatial period 2T along the scale. The windings are each divided in two identical winding elements having the same relative location within two identical winding element patterns having a center-to-center distance along the scale of NT+T/2, N being an integer, and connected so that the winding element polarities in each winding are either opposed for drive windings and the same for sense windings or the same for drive windings and opposed for sense windings. Thereby, direct couplings in both patterns cancel each other, while the spatially periodic signals coupled via the scale reinforce each other.

A method is provided for the application of a finishing layer to a textile support material. A water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues, and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state.

摘要:
The subject matter of the invention is a fuel pump nozzle, with an inlet (2), a discharge pipe (3), a main valve for controlling the stream of liquid between the inlet (2) and discharge pipe (3), a switching lever (4) for actuating the main valve, a first automatic safety shut-off which moves the main valve into the closed position if the liquid level in a tank to be filled reaches a filling level sensor arranged in the region of the discharge pipe (3), a second automatic safety shut-off which moves the main valve into the closed position if the liquid pressure at the inlet (2) drops below a minimum value, and a mechanism (13) for prestressing the main valve into the closed position, said mechanism bringing about a variable opening cross section of the main valve depending on the liquid pressure at the inlet (2). According to the invention, the main valve is pressed into the closed position in a tilted manner under the action of the mechanism for prestressing the main valve into the closed position in the full hose mode such that the tightness of said main valve is reduced.

A water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state. Additionally, textile articles are proved having the novel water repellent or oil repellent finishing layer which are equal on a high level or even superior with respect to their functional properties to products prepared according to known finishing methods and at the same time allow a complete or partial substitution of the health and environmentally hazardous standard chemicals employed nowadays by novel compounds which have not been used to date.

摘要:
The invention relates to a method for electro-catalytical hydrogenation of vat dyes and sulphide dyes in aqueous solutions, and to an apparatus for carrying out said method. The inventive method is suitable for batch operation and continuous operation. It works entirely without any reducing agents and provides a substantially salt-free dye concentrations of up to 200 g/l. The dyed threads are characterized by good friction qualities and by a high weaving yield. As far as waste water is concerned, no toxic load occurs and the salt loads are much lower, thereby enabling the waste water to be recycled in a substantially less complex manner in comparison with other conventional dye systems. The invention also relates to an apparatus for carrying out said method.
