Title: Determining glass fogging capability of substances - useful for testing plastics for use in vehicle passenger compartments
Inventor: KAMISKE DINAH JULIA
IPC: G01N21/55
Filed: 1992-02-13
Abstract: Determn. of the fogging property of a substance is carried out by exposing the substance to conditions causing evolution of volatile constituents in a chamber closed by a glass plate and then measuring the condensate layer thickness on the glass plate. The novelty is that the condensate layer thickness is constantly measured during condensation until the max. thickness value is reached and a fogging evaluation value is derived from the condensation times required to achieve predetermined layer thicknesses and/or from layer thicknesses measure after preset condensation times. Equipment for carrying out the process is also claimed. USE/ADVANTAGE - The process is useful for determining the tendency of the interior surfaces of vehicle windscreens to be fogged by volatile components released by plastics used in vehicle passenger compartments. A clear indication of the fogging capability, even of substances which give condensate films of time-dependent variable structure, is obtained with minimal time and process costs.

Title: Device for measuring distance by means of a telescopic arm; a steel strip is transported via a toothed wheel
Inventor: ATAR MUAMMER
IPC: G01B5/02
Filed: 1993-05-27
Abstract: The current measuring devices are expensive to procure or have complicated operating instructions or are deficient in measuring accuracy. Starting from a coil, a rolled-up steel tape measure runs further between two support rollers as far as the tip of the telescopic arm and sticks mechanically (is hooked) there. Each part of the telescopic arm has two coils at the tip. The steel tape measure therefore cannot move laterally. Unlimited use is possible at any desired angle setting and any location, and can be carried out by only one person. Can be used in construction, industry.
