A multilayer combustible heat source for a smoking article is provided, including a combustible first layer including carbon; and a second layer in direct contact with the first layer, the second layer including carbon and at least one ignition aid, wherein the combustible first layer and the second layer are longitudinal concentric layers having a density of at least 0.6 g/cm, and wherein the composition of the first layer is different from the composition of the second layer.

Multilayer combustible heat source

The method for producing the strain gauge device () comprises a first stop of producing the band (). The band () has flexibility at least in the measuring zone (). Then a sensor () comprising at least one measuring strand () and changing electrical resistivity in dependence of the strain is produced and arranged on or in the band () without pre-tension. Afterwards the shape of the band () is changed into a retaining working shape and thereby the measuring strand () is stretched to an amount of pre-tension.

Method for producing a strain gauge device

The invention relates to a method for the production of a sintered, microcrystalline &#x3b1;-AlO-based shaped body, which are used, for example, as abrasive bodies, wherein an &#x3b1;-AlOpowder is used as starting material, said powder having an average particle diameter of &#x3c;2 &#x3bc;m, and processed with at least one binder and a solvent with the purpose of obtaining an extrudable material that is subsequently extruded. The extrudate is then further processed into a shaped body that is sintered at a temperature range of between 1300&#xb0; C. and 1750&#xb0; C.
