Abstract: The present invention concerns a method for producing a plate heat exchanger (1) with a multiplicity of parting sheets (20) and a multiplicity of fins (11, 12), a fin being respectively arranged between two neighboring parting sheets, wherein at least one capillary (30) with at least one thermocouple and/or measuring resistor element (40) is introduced into at least one parting sheet (20), and wherein in each case a parting plate of the multiplicity of parting plates and a fin of the multiplicity of fins are alternately arranged and are connected to one another in a material-bonding manner, and concerns a plate heat exchanger (1) produced in such a way.

Abstract: A first communication subscriber transmits a first data packet comprising data and an identification character to the second communication subscriber. The first communication subscriber and the second communication subscriber respectively determine a first and a second acknowledgement character on the basis of the identification character. The second communication subscriber transmits a second data packet comprising the second acknowledgement character back to the first communication subscriber. The first communication subscriber can thus check, on the basis of the second acknowledgement character, whether the first data packet arrived at the second communication subscriber.

Abstract: A method is provided for regulating the pressure in a first vessel, having a substance mixture which is present in liquid and gaseous phases and which has a first component and a second component, wherein, in the method, the temperature of the substance mixture is set such that the pressure in the first vessel lies below a predefinable value and, at the set temperature and the pressure in the first vessel, the substance mixture is present only in the liquid and gaseous phases.

Abstract: The present invention concerns a method for measuring the thickness of any deposit of material on the inner wall of a structure conducting a fluid stream of hydrocarbons, the method comprising the steps of: applying a first heat pulse or continuous heating to at least one first section of the structure removing deposits on the inner wall of the first section of the structure; applying a second heat pulse to both the first section of the structure and at least one second section of the structure, the first and second sections being spaced apart, which heat pulse does not loosen any deposit of material in the second section; measuring the temperature of the wall of the structure or the fluid during the second heat pulse at both the first and second sections; and determining the thickness of any deposit of material on the inner wall of the structure at the second section based on the measured temperatures. The present invention also relates to a corresponding device and arrangement.

Abstract: A method of measuring the thickness of any deposit of material (28) on an inner wall (12) of a structure (14). The method comprises: (a) causing vibrations in the structure; (b) detecting said vibrations in the structure; (c) determining a resonance frequency of the structure based on the detected vibrations; and (d) determining the thickness of any deposit of material on the inner wall of the structure based on the determined resonance frequency.

Abstract: The present invention provides transdermal therapeutic systems for dispensing a pharmaceutical product, in particular a pharmaceutical product with a low tendency to spontaneously crystallize. The matrix layer or at least one of the matrix layers in said systems contains a silicone hot-melt adhesive, a pharmaceutical product, and particles made of crosslinked polyvinylpyrrolidone. The invention also relates to a method for producing said transdermal therapeutic systems.
