The invention relates to duplicating intaglio print elements in steel by using an engraved copper art model as a template for a copper electrode which in turn is utilized in an electro-erosion machining process to produce the steel workpieces. The invention is particularly applicable to making intaglio print elements for printing on bank note paper and more particularly for printing paper money.

Method and apparatus for duplicating steel intaglio print elements using

The present invention relates to a process for the application of a reflecting coating on a metallic surface such as sheet metal, whereby there is applied to the unpolished metallic surface, a layer of a pulverulent dressing; said layer is subjected to a heat treatment with a view to fixing it on the metallic surface and creating a surface having undulations coexisting with micro-fissures; the layer thus fixed is smoothed by the deposit of a layer of varnish intended to fill in the micro-fissures while conserving said undulations, and the surface thus obtained is then subjected to a conventional metallization operation. The invention finds particular application to the production of reflectors having a high power of reflection.

Process for the application of a reflecting coating on a metallic surface

The invention relates to a method for assembling together two parts of headlights or lights for automobile vehicles, the first of said parts being made of an inorganic material and the second of a thermoplastics material not able to be directly fixed to the first by adhesion, wherein a connection element is partially introduced into the second thermoplastics part so that a part of said element projects and acts as free anchoring element, and the two parts are then assembled together by the depositing of a layer of glue which, on the one hand, adheres to the first part and, on the other hand, completely covers the said free anchoring element.

Method for assembling together parts of automobile lights

A mounting arrangement for an accessory headlamp which allows the azimuthal direction of the headlamp beam to be adjusted and locked independently of the inclination of the beam. The mounting comprises a mounting bolt having larger and smaller diameter threaded portions separated by a shoulder. The smaller diameter portion passes through a mounting hole in the vehicle body and is secured by a nut, with the shoulder in contact with the body surface. The larger diameter portion receives a nut forming part of a clamping mechanism for the headlamp, which is pivoted to the top of the mounting bolt but can be locked by the clamping mechanism. In a modification, the larger diameter nut is replaced by a cam mechanism.

Accessory headlamp mountings

The invention relates to methods and devices for determining the position of the cut-off of the light beam from a motor vehicle headlight. A pair of light detectors D.sub.c and D.sub.1 are located on a screen and the headlight and screen moved relatively to one another until the light intensities I.sub.c and I.sub.1 satisfy the relation

Photoelectric determination of the cut-off of a light beam from a motor

A vehicle headlamp has a paraolic mirror with a lamp having a dipped beam filament disposed in front of the focus of the mirror. A front lens is adapted to be rigidly secured to the vehicle body whilst an auxiliary lens is mounted between the front lens and the lamp. The auxiliary lens is rigidly connected to the mirror so as to be movable therewith.
