IPC: C30B33/00
Filed: 1992-04-14
Abstract: The present invention relates to a method for making a unidimensional or bidimensional discontinuity lattice, in or at the surface of a crystalline substrate. The method according to the invention comprises the utilization or creation of areas favorable to the development of sources of dislocations in or at the surface of a substrate, and the activation of shear systems by subjecting the substrate to stress fields. When one or two stress fields are applied, a unidimensional or, respectively, bidimensional discontinuity lattice is achieved. Lattices are obtained wherein each element (lines or boxes) has either two or three dimensions of the order or the nanometre. The discontinuity lettices obtained may be used as active areas for microelectonic components, or as a support for the controlled growth of materials designed to provide quantum lines or boxes, for example.

Title: Weft tensioner - has nipper with two=way piston for shifting parallel to the shuttle movement axis line
Inventor: PIERRE-HENRI FABRE
IPC: D03D43/10
Filed: 1992-07-08
Abstract: The appts. to hold wefts under selective tension, on one side of the loom or the other for one or more shuttles, has a nipper with a two-way piston to control its movement, parallel to the shuttle movement axis. The moving section is harnessed to the nipper, and is fed successively with fluid pressure in the first place, to act with a retractable limit at the piston, for positioning to grasp the yarn. When the limit has settled, the fluid pressure is stabilised at the piston, to apply tension on the weft yarn through the nipper. The fluid pressure for the piston is controlled to apply the required tension to the inserted weft. The retractable limit is a plunger with a suitable controlled cylinder. The piston for the nipper operates it to relax the weft tension and release it. The piston moves the nipper laterally to a point where the jaw is forced open through a profiled boss, supported by a tilting member moved by a fixed roller. The boss can also be at the end of a fixed shaft at the required position. The nipper is carried by a swing lever, harnessed to the moving section of the piston. The nipper can also be at a trolley which is held rigidly by the moving section of the piston after movement along a guide parallel to the shuttle travel axis. USE/ADVANTAGE - The mechanism applies an equal tension to all the inserted wefts, to give a fabric of consistent quality.
