Abstract: The invention relates to a device for applying a foamable reaction mixture to a moving cover layer, comprising a mixing head (100) having at least two inlets (200, 300) and at least one outlet (400) for mixing components that produce the foamable reaction mixture, and a conduit (410, 420, 430, 440) connected to the outlet of the mixing head, through which conduit the foamable reaction mixture can flow, and which has a discharge element (500), from which the foamable reaction mixture can be applied to the cover layer. The conduit (410, 420, 430, 440) is designed to include at least two configurations, which differ in the path length, which the reaction mixture flowing through the conduit covers. The invention further relates to a method for applying a foamable reaction mixture to a moving cover layer using a device according to the invention.

Abstract: A system for linearized-mixer interference mitigation includes first and second linearized frequency downconverters; a sampling analog interference filtering system that, in order to remove interference in the transmit band, filters the sampled BB transmit signal to generate a cleaned BB transmit signal; an analog interference canceller that transforms the cleaned BB transmit signal to a BB interference cancellation signal; and a first signal coupler that combines the BB interference cancellation signal and the BB receive signal in order to remove a first portion of receive-band interference.

Abstract: A boom for a working machine, in particular a concrete-distributing boom for guiding a concrete delivery line, with a plurality of boom arms which can be moved into a working position and which are composed at least partially as a box construction of a plurality of side walls delimiting a cavity region, and with a sealing bulkhead arrangement for sealing a cross section of the cavity region, wherein the sealing bulkhead arrangement has a bulkhead wall provided peripherally with an at least partially encircling sealing groove, and wherein the sealing groove has arranged therein an elastic seal which bears tightly on the inside against the adjoining side walls.

Abstract: A differential pressure measuring pickup comprises a measuring pickup body and a differential pressure sensor. The measuring pickup body has a process interfacing surface with a first pressure input opening and a second pressure input opening. The differential pressure sensor can be loaded with a first pressure through the first pressure input opening and with a second pressure through the second pressure input opening. The first pressure input opening is closed by way of a first separating diaphragm and the second pressure input opening is closed by way of a second separating diaphragm. The first separating diaphragm is sealed with respect to the surroundings by way of a first seal, and wherein the second separating diaphragm is sealed with respect to the surroundings by way of a second seal.

Abstract: An inventive boom arm for a concrete-distributing boom. The boom arm has an elongate box-profile support formed from two flanges and two webs connecting the flanges laterally. The boom arm has first and second articulation points spaced apart in the longitudinal direction of the boom arm. A first flange opening is disposed at the first articulation point and a second flange opening is disposed at the second articulation point. A sealing-partition seals a cavity region of the box-profile support at least in a region of the first and second flange openings. The sealing partition can be provided in the form of a plate that continuously spans the cavity region between the first and second articulation points and is connected laterally to the webs. The first articulation point is located at the end of the boom arm and is arranged within the cavity region and is covered by the partition plate.
