Abstract: The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.

Abstract: A screening element 10 for screening particulate materials such as mineral ores of all types, shapes are a densities, as well as difficult to screen cloggy, and slabby materials. The screening element 10 has a screening surface 12 formed by a plurality of elongate zig-zagged shaped ribs 14. The ribs 14 are resiliently deformable and extend within the periphery of the element 10 in a chevron pattern across the element 10. The ribs 14 are spaced from each other to define between them rows of square screening apertures 22. The screening apertures 22 have sides 22.1 which are orlentated transversely at 90° to an axis 10.1 of the screening element 10; and sides 22.2 which are substantially aligned with the axis 10.1. The element 10 is divided into two rectangularly shaped portions 16, 18 by a centrally disposed straight rib 20. The ribs 14 extend, in the portion 16, at an angle A of approximately 315° to the axis 10.1; and in the portion 18, at an angle B of approximately 45° to the axis 10.1.

Abstract: A screening arrangement support frame component in which a pair of complementary elongate component members have body portions and cavity defining formations. The component members are secured side by side to one another such that the body portions abut and the cavity defining formations register to form a plurality of cavities for receiving socket elements. A plurality of socket elements, each defining a socket for receiving a protrusion that secures a screening panel to the component, the socket elements being mounted in the cavities when the component members are secured to one another. The thickness of each support frame component at the locations where the body portions abut is smaller than the cross-sectional dimension of the socket elements mounted in the cavities.

Abstract: A known servo-drive including a stator which is formed with two-component design or the exciter winding has to be attached directly to the stator, which is associated with a costly production method. The new servo-drive is to permit easy and cost-effective manufacture with favorable actuation properties. The stator of the servo-drive includes in the region of the poles, weak points which are formed either by recesses or by gaps. An induction core includes a winding which is inserted into a yoke constructed on the stator by which a magnetic field can be induced in the stator. The alternating combination of sheet-metal laminas having gaps and recesses permits the torque/rotary angle characteristic of the servo-drive to be optimized with favorable production properties. The servo-drive for rotary angle adjustment of an actuator is used for example to control the opening cross-section of a medium-conducting flow line in internal combustion engines for the purpose of controlling idling speed.

Abstract: A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.

Abstract: A control device for the control of an opening cross-sectional area of a flow duct, in particular for internal combustion engines, comprising three sub-assemblies, an actuator housing with flow channel and setting window, a rotor with a rotary valve for controlling the window opening, and a drive housing with stator and stator winding. For setting a required air gap between the rotary valve and the setting window, a control section of the rotary valve covering the setting window is designed as a cone envelope segment, and is inclined at an acute angle to the rotor axis. The window lying in a cone envelope plane is located at the same angle of inclination. By means of a spacing disk between the rotor, with the rotary valve affixed thereon, and the actuator housing, the air gap is set and fixed as required.

Abstract: A steel wire directly from the rolling mill is formed into a horizontally advancing helix having a succession of upstanding turns. This helix is fed into a horizontally opening end of an elbow and a roller at the short side of the elbow deflects the helix so that it exits from the downwardly opening outlet end of the elbow. An upright cooling tube is provided immediately at this downstream end and has a multiplicity of throughgoing holes each aligned with a respective nozzle for spraying of liquid on the descending coil so as rapidly to cool it and to transform at least the surface of it into martinsite. At the lower end of the tube the cooled coil, at a temperature of 500.degree. C.-600.degree. C. as compared with the starting temperature of 750.degree. C., is carried horizontally away by a conveyor.
