Abstract: A system for connecting rigid and flexible pipes with corresponding outer diameters, with a press jaw having a press contour, with a first fitting for press-fitting to a rigid pipe, the first fitting having a first press sleeve with a first outer contour, a second fitting for press-fitting to a flexible pipe, the second fitting having a second press sleeve with a second outer contour, the second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve being adapted in sections to the press contour of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections.

Abstract: The invention relates to a system for connecting rigid pipes and for connecting flexible pipes. The pipes have corresponding outer diameters, with a press jaw having a press contour, with at least one first fitting for press-fitting to a rigid pipe, the at least one first fitting having a first press sleeve with a first outer contour, with at least one second fitting for press-fitting to a flexible pipe, the at least one second fitting having a second press sleeve with a second outer contour, the at least one second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve in each case being adapted at least in sections to the press contour of the press jaw of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections.

Abstract: The invention relates to a biofilter for biologically cleaning a waste gas stream containing contaminants, having at least one filter module through which the waste gas stream is to flow. The filter module has at least one filter layer containing an organic filter material, and the at least one filter layer being supported by at least one grating structure which is in particular oriented at least substantially horizontally. According to the invention, so that the biofilter can be operated cost-effectively, with low effort and with a high filtering efficiency over the longest possible period, the at least one grating structure formed by elongate grating elements which are arranged at least substantially crosswise and are in particular oriented at least substantially horizontally.

Abstract: The present invention relates to a food composition and a pharmaceutical comprising D-tryptophan. The present invention further relates to D-tryptophan for use in the treatment, prevention or amelioration of a diseases associated with Treg or TH2 cells, such as allergy and in particular asthma.

Abstract: A fitting for attaching to a threaded connection of a pipe, in particular a water pipe, includes a basic body, a threaded portion, and a sealing body arranged on the threaded portion. The basic body has a pressing surface on the side situated opposite to the threaded portion. Also disclosed is a method for attaching a fitting to a threaded connection of a pipe.

Abstract: The invention relates to a fitting for producing a leaktight connection with a pipe end, having at least one pressing portion designed for pressing and the insertion of a pipe end, having at least one sealing and at least one retaining element. The sealing and retaining elements are arranged in the pressing portion. The retaining element is substantially annular. The annular shape defines axial and circumferential directions. The retaining element has two ends with respect to the circumferential direction. Specifying a fitting with a retaining element is achieved when the retaining element has, at each of the two ends, at least one contact surface extending at least partially in the circumferential direction. The contact surfaces are designed to be brought into contact with one another upon pressing the pressing portion. The invention relates to a system and method for producing a leaktight connection between a pipe end and fitting.

Abstract: The invention relates to a fitting for attaching to a threaded connection of a pipe, in particular a water pipe, with a basic body (20), with a threaded portion (22) and with a sealing body (24, 50, 56; 62) arranged on the threaded portion (22), in which the technical problem of simplifying the attachment to a threaded connection of a pipe and configuring the attachment to be more reliable at the same time is solved in that the basic body (20) has a pressing surface (26, 66) on the side situated opposite to the threaded portion (22). The invention also relates to a method for attaching a fitting to a threaded connection of a pipe.
