Abstract: Apparatus (1) for generating a light beam via at least first and second light sources (2, 3). During operation, the light sources (2, 3) emitting light at the same wavelength. The light sources are arranged such that the beam profile (11) of the first light source is rotated relative to the beam profile (12) of the second light source by a rotation angle (D) about an axis (A) in the direction of propagation. A beam rotation element (4) is located downstream of at least one of the light sources, which causes the beam profile (11, 12) to rotate such that the beam profile (11, 12), after passing through the beam rotation element (4) in a plane perpendicular to the direction of propagation (A) of the light, is oriented substantially identically to the beam profile of the other light source (2, 3) in the plane perpendicular to the direction of propagation.

Abstract: An installation for guiding a gas for devices used to treat granular products by drying, film-coating or coating includes: a central distribution channel that can be connected to a gas supplying device and is connected to outlets for the gas, that are arranged at a distance from the central distribution channel in an axial direction, via connection channels. The installation includes a functional channel which is arranged at a distance from the distribution channel and has a plurality of outlets, and the functional channel includes at least two axially interspaced inlet regions, each being connected to the distribution channel via a connection channel. The outlets are arranged, in the axial direction on the functional channel, between the mouth of two connection channels, which are adjacently arranged in the axial direction, in the functional channel.

Abstract: The invention relates to an installation (1) for guiding a gas for devices (44) used to treat granular products (56) by drying, film-coating or coating, especially an air intake unit, comprising a central distribution channel (2) that can be connected to a gas supplying device and is connected to outlets (6.1, 6.n) for the gas, that are arranged at a distance from the central distribution channel in an axial direction, by means of connection channels (3, 4). According to the invention, the installation comprises a functional channel (5) which is arranged at a distance from the distribution channel (2) and has a plurality of outlets (6.1, 6.n). Said functional channel comprises at least two axially interspaced inlet regions (11, 12). Each inlet region (11, 12) is connected to the distribution channel (2) by means of a connection channel (3, 4). The outlets (6.1, 6.

Abstract: A process for manufacturing porous textile substrates impregnated with thermoplastic polymeric pastes, especially fleeces or mats, with subsequent gelling out of polymeric paste, which comprises penetrating impregnating one side of a textile substrate with an evacuated paste comprised of a vinyl polymer and/or copolymers of vinyl chloride, while effecting complete displacement of air through the paste and compactly impregnating said substrate.
