Abstract: Plastisols useful for automobile undercoatings, anti-noise compositions, adhesives, sealing compositions and coatings for untreated, pretreated, phosphated, primed and prelacquered metal bases are improved by the addition of coke dust and coal dust fillers. The carbon dust fillers have a particle size of about 0.5 to 1000 microns and they are used in a concentration of about 9 to 90% by weight based on the total weight of plastisol and carbon dust. The carbon dust filled plastisols have a specific gravity of about 1.1 to 1.3.

Abstract: The invention relates to a process and a device for transferring a liquid from a stationary feeding component onto a working part which is rotationally driven, for example a spraying-bell, by generating a thin sheet of liquid in the shape of a conical shell, which is stable over a distance of travel which can be defined, it being possible to define the apex angle of this shell in terms of the functional parameters of the liquid, so that it is possible to select different impact positions of the thin sheet of liquid on the transfer portion of the spraying-bell, depending on the particular liquid in question.

Abstract: Objects are coated using electrostatically charged powder grains by feeding an air-powder mixture to a spray bell, fanning out the flow of the air-powder mixture and centrifuging the powder particles off the spray head. The powder particles are conveyed onto the object to be treated by applying an electric field between the spray bell and the object. A fluidized flow of powder, that is, a flowable mixture of air and powder, is supplied at low speed to the spray bell, accelerated minimally when passing into the rotating bell, then accelerated by the bell to 500 to 6000 rpm, transported to the rim of the bell and there centrifuged off.

Abstract: A process for introducing one or more threads into a texturizing nozzle, in which the texturizing nozzle, together with the inlet member, is first brought into a position in which the thread is led transversely past and in the immediate vicinity of the texturizing nozzle, the thread is sucked against the nozzle with the orifice of the inlet member enlarged, immediately after being sucked against the texturizing nozzle the thread is cut beyond the nozzle so that the cut end is sucked back into the nozzle, the suction supply required for the sucking-in is replaced by pressurized fluid texturizing medium, and the cross-section of the inlet orifice of the texturizing device is reduced to a value advantageous for steady state operation.
