Patent FR-2268287-A1 (FR)
Title: Production of negatives for thick film circuits - uses metallic deposition on partially conducting substrate
IPC: G03F7/12
Filed: 1974-04-16
Abstract: The production of thick film printed circuits is facilitated by this invention, which uses silkscreen technique. Better definition is achieved than when the image is transferred to sensitised silk and stronger negatives than when resin or colloidal films are used. With silk screens, the size of the mesh is critical and different orientations may be required in different part of the image. This method allows both different mesh sizes and different orientations on the same negative. The combined "silk" -negative is obtained basically by photo chemical means which produce a thin metallic image of the required circuit. The substrate may be metallic, covered by an insulating mask or an insulator covered with a metallic mask.

Title: Automatic strip thickness control in tandem mill - corrects thickness at differents speeds through first or second, or first and second stands respectively
IPC: B21B37/16
Filed: 1975-08-28
Abstract: Thickness control of a strip in a tandam mill having >=3 roll stands is effected firstly at a low strip speed by sensing an error in the strip thickness between first and second stands and correcting the error solely at the second stand downstream of the first stand. The error is then sensed at a higher strip speed between the first and second stands and corrected at a stand downstream of the second stand. Strip thickness error is then sensed between the first and second stands at an intermediate speed and corrected at the second stand and a stand downstream of the second stand. The proportion of error corrected at the second stand decreases as the speed rises and increases at the stand downstream of the second stand. the thickness error correction is obtained over a wide range of strip feed speeds without the use of variable time delays. The ratio of the correction applied in the stands at any given strip feed speed is modified during a long term strip thickness error so as to distribute the rolling loads between the stands to avoid load concentration at a single stand.

Title: Loom with vertically moveable reed - to cooperate with selected weft pickers and single rotary cam controlling reed and pickers
IPC: D03D35/00
Filed: 1976-01-23
Abstract: Loom for e.g. weaving tapes has a reed which is moveable vertically to positions adjacent weft pickers arranged one above the other. A weft picker associated with a selected weft yarn is picked and moves across a track on the reed. Vertical movement of the reed and picking of the selected weft picker is controlled by a mechanism including a cam element mounted essentrically on a main drive shaft and having a large arcuate track and a small acruate track concentric with the shaft. A first control rod is connected at one end to a reciprocating drive for moving the reed and at the other end has a roller which runs in the cam element, the roller being connected to one end of a stabilising lever the other end of which is connected to a fixed pivot point. The actuation of the weft pickers is controlled by a second control rod which is pivoted at one end and which is connected to a reciprocating drive at the other end. The second control has a roller at an intermediate position and which runs in the cam. Rotation of the cam causes the drives to actuate the reed and weft pickers. The device is simple, cheap, compact and produces controlled movement of the reed and weft pickers.
