Patent FR-2572683-A1 (FR)
Title: Method of decorating moulded objects
IPC: B44C3/04
Filed: 1984-11-08
Abstract: The invention relates to a method enabling the fast and efficient decoration of moulded objects where this decoration does not require precise outlines as in the case of the manufacture of garden furniture from concrete imitating millstone rock. For this purpose, use is made of cloth pads containing powdered metal oxides of different colours which are rubbed on the inside of the silicone elastomer mould. When these moulds are filled with a hydraulic cement-based mix, the oxides are transferred to this mix during the setting process. This method is faster and more convenient than that in which the work is performed directly on the moulded object.

Patent FR-2560539-A1 (FR)
Title: Thread cutting nut with thread alignment adjustment
Inventor: GRABULOSA MIGUEL GRAU
IPC: B23G5/04
Filed: 1985-01-14
Abstract: The thread cutting nut which is secured into a holder by grub screws has cutting threads (3) which are interrupted by openings (2) in the conventional manner. This gives resilience during cutting and tangential to these circular openings are smaller openings into which pegs (6) are inserted. Due to the increased resilience, the thread sections are distorted when the pegs are inserted, so that their contact surfaces are still further decreased. Due to the distortion, the teeth are aligned to follow a radius (R) greater than the thread circle radius, ensuring minimum contact. The pegs which are slightly larger than the small circular openings, are forced in permanently.
