Abstract
A device for passing through a gas mixture comprises a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary tapers from one side towards the other side of the capillary apparatus at least in sections.
Claims20
A device for passing through a gas mixture containing a predetermined gas with a mean free path, comprising:
- a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein:
- each capillary tapers from one side towards the other side of the capillary apparatus at least in one of a first section and a second section;
- a cross section of each capillary changes abruptly between the first section and the second section, and
- a minimum cross section of each capillary, in at least one direction, has a dimension that is the same order of magnitude as the mean free path of the predetermined gas.

A detector device for qualitatively or quantitatively detecting the presence of a predetermined gas in a gas mixture, comprising:
- a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary tapers from one side towards the other side of the capillary apparatus at least in sections;
- a pressure detector connected to the second side;
- and
- an evaluation apparatus which is connected to the pressure detector for receiving a measurement signal from the pressure detector, wherein the evaluation apparatus is configured to generate an output signal on the basis of the measurement signal which indicates at least one of:
- (i) the presence of the predetermined gas in the gas mixture at a minimum concentration, (ii) the partial pressure of the predetermined gas, (iii) the proportion by volume of the predetermined gas, and (iv) the proportion by material of the predetermined gas.
2 more elements
A gas enrichment device for extracting a predetermined gas from a first gas mixture or for enriching the predetermined gas, comprising:
- a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary tapers from one side towards the other side of the capillary apparatus at least in sections, the capillary apparatus being configured such that the predetermined gas has a higher through-passage rate than other components of the first gas mixture;
- a first gas container that is connected to the first side of the capillary apparatus and is filled with the first gas mixture which contains the predetermined gas at a first concentration;
- and
- a second gas container that is connected to the second side of the capillary apparatus and is filled with a second gas mixture which contains the predetermined gas at a second concentration, the second concentration being substantially greater than the first concentration.
1 more element
A device for generating mechanical power, comprising:
- a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary tapers from one side towards the other side of the capillary apparatus at least in sections;
- and
- a device for depressurizing gas and for generating mechanical power, wherein an entry side of the device for depressurizing gas is connected to one of the sides of the capillary apparatus, and wherein an exit side of the device for depressurizing gas is connected to the other side of the capillary apparatus.
A device for inducing a rotational movement, comprising:
- a shaft;
- a capillary apparatus with one or more capillaries connecting a first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary tapers from one side towards the other side of the capillary apparatus at least in sections;
- a pointer which is connected to the shaft and indicates its rotation angle;
- and
- a spring which is connected to the shaft and exerts a torque on it which is dependent on the rotation angle, wherein the position of the pointer indicates at least one of:
- (i) a gas composition, and a partial pressure of a predetermined gas in a gas mixture.
3 more elements
A method for passing through components of a first gas mixture, comprising:
- supplying the first gas mixture which contains a predetermined gas at a first concentration to a first side of a capillary apparatus, the capillary apparatus comprising one or more capillaries that connect the first side of the capillary apparatus to a second side of the capillary apparatus, wherein each capillary is tapered in at least one section, the capillary apparatus being configured such that the predetermined gas has a higher through-passage rate than other components of the first gas mixture;
- and
- discharging a second gas mixture which contains the predetermined gas at a second concentration, the second concentration being substantially greater than the first concentration.
