Abstract: The present invention relates to a process for the preparation of aqueous dispersions or solutions of polyurethanes which have urea end groups and contain non-ionic hydrophilic segments and which are capable of being cross-linked with the aid of cross-linking agents which are reactive with urea groups, characterized in that prepolymers which have isocyanurate end groups and which (i) have an average molecular weight of less than about 15,000 and (ii) contain from about 2 to 30%, by weight, of ethylene oxide units corresponding to the following formula: -CH2-CH2-O-  within a polyether chain (containing ethylene oxide units) are reacted at from about 10 DEG to 70 DEG  C. with an aqueous solution of ammonia or with a primary amine, optionally dissolved in water, the aqueous solution of ammonia or the primary amine, optionally dissolved in water, being added to the prepolymer in the reaction vessel and the quantity of water used for dissolving the ammonia or primary amine being not more than about 10%, by weight, based on the total quantity of reaction mixture, and finally, after termination of the addition reaction between the free isocyanate groups of the prepolymer and the added ammonia or primary amine, the reaction product obtained is stirred with water at from about 10 DEG  to 70 DEG  C. to form an aqueous dispersion or solution having a concentration of from about 5 to 65%, by weight. The present invention also relates to the use of dispersions or solutions obtainable by the process according to the present invention for the production of cross-linked sheets by application of the dispersion to a substrate and drying, cross-linking of the sheet being ensured by the addition of a cross-linking agent capable of undergoing a cross-linking reaction with the urea groups either before, during or after application of the solution or dispersion to the substrate.

Abstract: An integrated switching and transmission network comprises a digital switching system for transferring communication information without congestion. The switching system consists of one-way switch modules (SM) which are connected through two-way time division multiplex transmission links (La-Lb) to link modules (LM) each including a control unit (CU) for establishing communication paths within an associated line group (LG) as well as for controlling the switching system in cooperation with the control units of other line groups. Each of the switch modules (SM x/y) is allotted to two of the two-way links and comprises a time stage (TS) and a signalling logic circuit (SL). The input of each module is connected exclusively to one way (La, x) of one (La, x-Lb, x) of the two-way links, whereas the output of each module is connected exclusively to the other way (Lb, y) of the other two-way link (LayLby). For the reliable control of the network, transmitting control units generate signals. Each signal addresses one of the signalling logic circuits, which converts the signal to an operation signal by which the associated time stage is operated or to a signal intended for the receiving control unit. Furthermore, control messages are used and transferred between the control units through the time stages. The time stages carry out the required time interchanges for the transfer of said control messages and communication information between the line groups.

Abstract: A mixture of vital wheat gluten and starch containing at least 25% protein, e.g. a protein-rich fraction of wheat flour, is treated with a bacterial alpha-amylase (preferably substantially free of protease) under conditions which solubilize the starch but do not unduly solubilize, or denature, the vital gluten. Specifically, the temperature should be not above about 60.degree.C and the time of treatment should not exceed about 6 hours.  After the enzymatic treatment the gluten, which still retains its vital properties, is separated out, and the solubilized starch fraction is recovered or subjected to further processing.

Abstract: The invention is concerned with a shank adaptor for a rock-drilling machine provided with at least one side flushing hole which connects an axial flushing hole of the adaptor with the outside thereof and which, together with the axial flushing hole, serves as a passage for transporting flushing medium. The side flushing hole has an oblong cross-sectional shape with the longitudinal axis of the oblong parallel to the longitudinal axis of the shank. The shank adaptor of the invention enables stress concentration at the outer edge of the side flushing hole to be reduced while decreasing hole-edges sensitive to fractural impressions by half, which also results in a reduction in the probability of fatigue cracks caused thereat by the rotary bending forces on the adaptor.

Abstract: The arrangement serves for the high-speed compressive forming of metals. It is envisaged that an elastic body (18), which is accommodated in the cavity of a high-pressure chamber (17), interacts with the working end face (19) of a percussion piston (3) and acts on a semi-finished product (20), is made in such a manner that the action of the same on the semi-finished product (20) in the shape-changing zone of the same can be guaranteed. In this case, the working end face (19) of the percussion piston (3) has a cross-section which is smaller than the cross-section of the cavity of the pipe (1) and it corresponds in shape to the surface of the elastic body (18) which comes into contact with it.

Abstract: A hollow body (e.g. a container) as well as a method and an apparatus for its manufacture in which an axially directed wall of the body primarily is made of oriented and/or crystallized plastics material. A tubular preform (10d) is fixed in a circumferential region (13d) in the vicinity of the mouth edge (14d) of the preform between mechanical forming devices (30,40), after which the devices, during continued clamping of the circumferential region, are displaced in the axial direction of the preform relative to a mandrel (50). Thus, the mandrel is displaced into the preform during simultaneous expansion thereof and the material is oriented and/or crystallized. In a preferred embodiment there is made a certain compensation of the stretching forces, which arise in the material when inserting the mandrel, by applying a force to the bottom of the preform by a bottom support (75).

Abstract: In a glass reactor which incorporates a turbine stirrer, 400 ml of sunflower oil and 20g of nickel catalyst are mixed, involving 82 per cent nickel on a carrier of silicone dioxide-aluminium trioxide. The mixt. is heated to 180 deg. C., after which hydrogenation is commenced. Hydrogen gas is added at the rate of 25 ml/s (1 atm., 25 deg. C). Using a gas controlled feed coil of known volume (5.43 ml), different quantities of hydrogen sulphide are fed to a gas mixer, in which the main hydrogen gas flow is allowed to carry with it the hydrogen sulphide into the hydrogenation reactor. A flame photo-multiplicator reactor is connected to the reactor outlet, and permits a rapid and simple determn. of the amount of hydrogen sulphide absorbed by the catalyst. In all cases, the hydrogenation time is 70 minutes.
