Patent FR-2613898-A1 (FR)
Title: Method of soldering surface-mounted components (SMC) on a printed circuit
Inventor: SULLET BERNARD
IPC: H05K3/34
Filed: 1987-04-13
Abstract: The invention relates to a method enabling the metal leads of a surface-mounted component to be soldered to the metal lands (pads) of a printed circuit, with the aid of a wave-soldering machine. Capillarity paths, formed in the printed circuit, make it possible to pick up the liquid tin/lead while passing over the wave and to convey it to the contact of the leads with the metal lands (pads) on the side containing the components. The formation of the capillarity path is described hereinbelow. It consists of a metal land (pad) 9, a plated-through hole 10 and a metal land (pad) 11. The axis of the hole 10 is located in the vicinity, that is within 25 mm, of the area of contact between the lead 8 and the land (pad) 9. The method according to the invention is particularly intended for the electronics industry for soldering surface-mounted components onto a printed circuit.

Title: Process and plant for the manufacture of a metal sheet pile, by the cold profiling of a metal sheet, and cold-profiled metal sheet pile resulting therefrom
Inventor: LIBERT BERNARD
IPC: B21D5/08
Filed: 1987-04-14
Abstract: The invention relates to a process and a plant for the manufacture of a metal sheet pile, by the cold profiling of a metal sheet 3, by passage of this metal sheet between pairs of rollers 6, 7 arranged one after the other on a profiling machine, the sheet pile being of the type formed by a web 3c having a particular non-planar profile, provided on both its longitudinal edges with a loop 8. The process is characterised in that first of all the loops 8 are profiled, by passing between the first heads 6 of rollers, and then in that the web 3c is profiled whilst leaving the previously formed loops 8 out of contact with the pair or pairs of rollers 7 which profile the web. Applicable to the manufacture of sheet piles, the loops of which have mutually complementary shapes.

Title: Data processing apparatus
Inventor: BRENT SUMMERS
IPC: G06F17/40
Filed: 1988-08-11
Abstract: A radar apparatus includes a data processing apparatus in which a data processing parameter is obtained by executing a pre-analysis of the data to be processed. Thus, the data received are processed (11 to 14) in such a way as to produce a parameter, which can be for example the maximum signal/noise ratio, after which the parameter is used to process (15) the data received. The data themselves are therefore used to set an optimal value of the parameter, in contrast to the prior devices in which the values of the parameters were prescribed.
