## Abstract

For the secure positioning combined with a quick regulation of the thermal equilibrium of thin layer resistances, especially in hot film anemometers, there are used holding devices in which the thin layer resistance 2 is rested on at least three pointed supports 4 of a holding clamp 1 and is pressed on at least two of the supports 4 with clips provided with spikes.

## Claims

### Claim 1

A device for holding a plate-shaped thin layer electrical resistance of the type where a thin metal layer is carried on an electrically insulating carrier, said device comprising holding clamp means, said holding clamp means including at least three pointed support means and at least two clip means each provided with spikes being arranged to press a thin layer resistance located between said spikes and said support means toward said support means.

### Claim 2 (depends on 1)

The device as claimed in claim 1 wherein at least two tongue means are provided for engaging portions of the thin layer electrical resistance.

### Claim 3 (depends on 2)

A device according to claim 2 wherein the tongue means are constructed so as to be adapted as contact surfaces for a bonded wire connection.

### Claim 4 (depends on 2)

The device as claimed in claim 2 wherein the tongue means are wedge-shaped, each having an edge for engaging a portion of the thin layer electrical resistance, and a fourth pointed support means is provided with each of said four pointed support means having clip means for holding a thin layer electrical resistance in association with a said support means.

### Claim 5 (depends on 1)

The device as claimed in claim 1 wherein a carrier body is provided and said clamp means are secured to said carrier body.

### Claim 6 (depends on 4)

The device as claimed in claim 4 wherein the carrier body is provided and said clamp means are secured to said carrier body.
