Title: Refractory mineral-metal amalgam, process for its preparation and its applications
Inventor: MORET CLAUDE
IPC: C22C32/00
Filed: 1987-01-26
Abstract: Refractory mineral-metal amalgam. This amalgam is characterised in that it consists:   - in the case of approximately 30 to 70 % by weight, of fine particles of at least one molten metal, which are coated with a vitrified material, - in the case of approximately 70 to 30 % by weight, of the said vitrified material; the vitrification temperature of the said mineral being lower than the melting temperature of the said metal, - of carbonaceous residues originating from the decomposition of polyurethane at high temperature,   - and of a few cavities which make the said material porous.   An improvement in the temperature behaviour is thus obtained, permitting its use in the armament, nuclear, aeronautics and space industries.

Title: System for clipping together two elements
IPC: F16B5/07
Filed: 1988-02-26
Abstract: A system of joining two parts consisting of two identical elements (10) which are made up of a base (8) on which are a series of equi-spaced ribs (16). On the top of the ribs are horizontal lips (17,18) which are elastically deformable. In the joining of the two parts (10), an element is inverted so that the lips face each other and the lips (17,18) are forced between the narrow gaps (20) of the other element and, as the material is pliable, the lips are able to deform and enter into the space between the ribs. Once in this space, the lips are able to take up their original shape and clip the two elements together. By pulling at the ends of the two elements (10), the two halves can be progressively separated.

Title: Universal punching tool
IPC: B21D28/34
Filed: 1989-01-06
Abstract: The invention relates to a universal punching tool. The one-piece mechanism of the universal tool, with its plunging striking head 1 and its punch holder 2 to which the short punches 3 are attached, receives the guide 4 fitted with its plate (sheet) grip 5. This universal tool, with its plunging striking head to which the punch holder is attached, can receive short punches as well as the corresponding plate grips whose particular design allows simple and effective attachment to the guide. This design of the tool avoids the use of a specific assembly for each punch and, in addition, allows the punch to be sharpened over a length of 10 mm. This results in an obvious saving as regards the duration of use of the punch. The application of these tools is particularly advantageous on punching machines having turrets.
