Abstract: The invention relates to a means in the form of a test strip and a method for the rapid determination of the content of aldehydes in samples.

Abstract: A container (1) for a plurality of test strips, in particular for strip-shaped indicator sticks, has a housing lower part (2) and a housing upper part (3), which can be brought into engagement with the housing lower part (2) in a positive manner, where the housing upper part (3) has an opening with a sealing flap (14) mounted in a pivotable manner, where the housing lower part (2) has a plurality of projecting snap-in elements (7), which can be brought into engagement with matched recesses (10) of the housing upper part (3), and where the sealing flap (14) is connected along its periphery to the housing upper part (3) by means of at least one connecting strip which can be torn off. The snap-in elements (7) project by more than one wall thickness of the housing upper part (3) in the region around the recesses (10). The sealing flap (14) preferably has a tear-off connecting strip on each of two opposite sides.

Abstract: The present invention relates to a composition and a method for the determination of furfurals, in particular the chemical signal substances 5-(hydroxymethyl)furan-2-carbaldehyde (hydroxymethylfurfural, HMF) and furan-2-carbaldehyde (furfural). The determination according to the invention is based on a liquid- or dry-chemical test using barbituric acid derivatives and 4-aminophenazone derivatives.

Abstract: In order to house a latent heat storage device in a vehicle in a manner which saves as much space as possible and at a site which is secured against accident-caused deformations, the latent heat storage device is installed in the passenger compartment in the area of the front passenger's foot space.

Abstract: There is described a multicylinder fuel injection pump which is provided with a device that extends the length dimension thereof. The device includes a longitudinally shiftable piston disposed in a chamber that opens into the fuel injection pump. The shiftable piston includes perpendicularly disposed pin means arranged to cooperate with a fuel rack. In the rest position of the piston the regulating movements of the fuel rack caused by the governor are either unhindered because of the correspondingly long recess in the fuel rack, or limited to a predetermined travel path.
