Patent FR-2553312-A1 (FR)
Inventor: MOREL MICHEL
IPC: D21G1/02
Filed: 1983-10-14
Abstract: At an installation comprising a roll stand having at least one roll of the variable camber type, comprising a fixed support and a casing carried by at least three jacks and rotationally movable about the support, the pressure of the fluid in each of the jacks (14), the position of the pistons of these jacks, the speed of rotation of the roll, and the flatness and thickness of the flat product are measured. The position of one of the jacks (14b) is controlled by the thickness measurement. The pressure in the other jacks (14a, 14c, 14d, 14e) is controlled by the pressure in the one jack (14b). The positions of the end jacks (14a and 14e) are compared and the pressure in the jacks (14) is modified in order to bring the tilt of the roll to a suitable value. The deformation of the fixed support is calculated and the shape of the generatrix of contact of the roll is determined. The pressure in the jacks (14) is modified in order to bring the generatrix to a reference shape. The invention is particularly applicable to four-high rolling mills having variable camber supporting rolls.

Title: Escapement wheel and timepiece with lever escapement usable in a flare mortar shell fuse
Inventor: PINEAU JEAN-PIERRE
IPC: G04B15/14
Filed: 1985-10-08
Abstract: The invention contributes to improving the operation of a timepiece of the type with lever escapement and in particular the stability of the mechanism, and hence the beat frequency. The invention relates more precisely to the shape of the teeth of the wheel. Each of these possesses a front face 12 and a back face 13 which are defined by the direction of rotation of the wheel. The front face makes an acute angle with the root diameter 15 of the wheel so that the lifters 8 and 9 of the escapement lever 3 can penetrate virtually as far as the root of the tooth. These lifters bear against the tooth via a curved surface 11 tangential at the point A to the upper portion of the front face and which extends as far as the end of the tooth constituted by the ridge 14. This shape of tooth tends to eliminate shocks between the lifters and each of the teeth, and hence promotes uniformity of operation. A use is provided for within a timepiece of the type with lever escapement used in a flare mortar shell fuse.
