摘要:
A module for textile machines has a plurality of tools (2) with retention portions (6). The retention portions are grasped in a plastic body (7), which reaches out or embraces the retention portions (6) at one or more recesses (15, 27, 28). The plastic body serves to fix the tools (2) positionally correctly with respect to one another. The positioning of the tools (2) with respective to a dividing sinker (11), however, is effected by direct contact between the retention portions (6) and the dividing sinker (11). By filling the gaplike interstices, which exist between the retention portions, with plastic, a compact yet lightweight retention region (4) for the module (1) is obtained.

An injector for uniformly distributing solids or liquids over surfaces. The injector includes at least two individual injectors each having an internal guide element and an external guide element. The injector includes a double jacketed tube with an inner tube and an outer tube. The injector includes a base body connected to the tubes of the double jacketed tube, and connecting the inner tube to the internal guide element and a region between the inner and outer tubes to the external guide element. The base body and the injectors are arranged such that a mixture of carrier gas and solid particles or liquid droplets which is supplied through the inner tube and a propellent gas which is supplied through the region lead to a turbulent flow mixture of propellent gas, carrier gas and solid particles or liquid droplets and to the turbulent flow mixture formed being distributed radially and uniformly.

A device for producing photographic exposures of images appearing on an image screen onto a film platform carrying a plane film comprises a support holding a number of objectives and displaceable parallel to the axis extending through the central point of the image screen and the central point of the film platform. The platform carries one objective fixed to the platform of one magnifying property and four additional objectives which have such magnifying properties that each of them projects the picture field area of the screen on only one fourth of the usable film surface.
摘要:
Particulate olefin polymers are prepared by catalytic polymerization of monoolefins in an auxiliary liquid containing the monomers to be polymerized in dissolved form and the particulate polymer product in suspended form. The reaction mixture is recycled in a loop to which the starting materials are fed and from which the particulate polymer formed is removed. The essential features are (a) that a side stream is branched off from the loop, (b) that the side stream is caused to pass through a separating zone in which particulate olefin polymer is separated by centrifugal acceleration at temperatures and pressures in the same range as present in the loop and (c) that the separated particulate olefin polymer is discharged through flashing means.
