The colorimeter has three sequentially operated light sources which have different spectral radiation characteristics in the visible spectral range. The light from the sources is radiated onto a measuring surface. The arrangement has a reception channel to measure the light returned from the measurement surface. Radiated and returned light have a shine suppressing measurement geometry. The spectra...

In a fuel injection device which supplies fuel to an internal combustion engine via an electromagnetic valve composed of an electromagnetic coil arranged in a casing and a fixed core having a non-magnetic portion 11 interposed between magnetic portions 12, 13, the fixed core is an integrated structure rather than a conventional structure in which the non- magnetic portion is bonded between the mag...

In un pneumatico per veicoli, provvisto di una fascia battistrada (9) realizzata con mescola a basso contenuto di nero di carbonio vengono previsti uno o più inserti conduttivi (12) in elastomero ad alto tasso di nero di carbonio, inglobati nella fascia battistrada stessa ed estendentisi, secondo uno sviluppo anulare, lungo l'intero sviluppo circonferenziale di quest'ultima. Ciascun inserto condut...

One or more streams of tobacco in a rod making machine are tested by several density monitoring units one of which employs a source of nuclear radiation and at least one other of which employs a source of optical radiation. The resulting density signals are evaluated and converted into signals which are devoid of the influence of changes of color and/or blend of fibrous material in the stream or s...

Recycling of solid or porous (e.g. foamed) plastics consisting wholly or partly of polyurethane to give end-prods. which do not contain toxic or additional by-prods. is effected by working-up the starting material to give a mixt. of low OH no. and then conventionally converting this to the end-prods. The process comprises (i) either (a) swelling the starting material (e.g. polyurethane scrap) in a...

It is possible using this apparatus to inspect surfaces for defects and contaminations in a non-destructive fashion over the entire area, both microscopically small punctiform or linear defects and the finest macroscopic inhomogeneities being detected.
