Abstract: The present invention relates to a composition, in particular a cosmetic or dermatological composition, comprising: a) at least one merocyanine corresponding to formula (3) below, and also the geometric isomer forms, notably the E/E- or E/Z-geometric isomer forms, thereof: in which: A is —O— or —NH; R is a C1-C22 alkyl group, a C2-C22 alkenyl group, a C2-C22 alkynyl group, a C3-C22 cycloalkyl group or a C3-C22 cycloalkenyl group, it being possible for said groups to be interrupted by one or more O; and b) at least one compound chosen from suitably selected gamma-butyrolactones and gamma-butyrolactams. The present invention also relates to a non-therapeutic cosmetic method for caring for and/or making up a keratin material, comprising the application, to the surface of said keratin material, of at least one composition as defined above.

Abstract: The invention relates to a heat exchanger for indirect heat exchange between a first medium and a second medium, comprising a shell surrounding a shell space which extends along a longitudinal axis. The shell space serves for accommodating the first medium. A tube bundle is arranged in the shell space having multiple tubes for accommodating the second medium. The tubes are helically coiled in multiple tube layers onto a core tube. The tube bundle has a multiplicity of inner tube layers, surrounding the core tube, and a multiplicity of outer tube layers, surrounding the inner tube layers. The heat exchanger discharges a part of a gaseous phase out of the shell space from the region of the inner tube layers via a gas discharge device, and/or supplies a gaseous phase into the shell space in the region of the outer tube layers via a gas supply device.

Abstract: The invention relates to a heat exchanger for indirect heat exchange between a first medium and a second medium, comprising: a shell, which surrounds a shell space of the heat exchanger, a core tube, which extends along a longitudinal axis and onto which a plurality of tubes for receiving the first medium are coiled. The tubes form a bundle and a number of end portions of the tubes are brought together and connected to a tubesheet fixed on the shell. An annular channel is provided for receiving the second medium (M2). An inlet nozzle is provided for introducing the second medium into the annular channel (100). A plurality of distributor arms in flow connection with the annular channel are provided for distributions.

Abstract: The invention relates to a heat exchanger having a core tube onto which tubes forming a tube bundle are coiled, a pre-distributor having a liquid space for receiving a liquid phase (F), a centrally arranged feed for introducing the liquid phase into the liquid space and a main distributor which has a multiplicity of distributor arms for distributing the liquid phase (F) over the tube bundle, wherein the distributor arms via at least one flow path proceeding outside the core tube are in fluidic connection with the liquid space, wherein the core tube is arranged or sealed off with regard to the liquid space in such a way that the liquid phase from the liquid space is not introduceable via the core tube into the distributor arms of the main distributor.
