Title: Ribbon with scalloped side hem and process for its manufacture
Inventor: CHEYNET RENE
IPC: D03D5/00
Filed: 1985-01-24
Abstract: This ribbon is of the type in which the scalloped hem is produced by means of a yarn 4 of multistrand synthetic material entering the yarns 2-3 of the selvage, forming a scalloped picot. According to the invention each of the scallops of the scalloped hem is fixed by heat-setting, in the selvage, a yarn 5 forming the scalloped hem. The process for its manufacture consists in adding to the multistrand yarn 4 made of synthetic material constituting the scalloped hem a single-strand yarn 5 which can melt at a temperature which does not destroy the ribbon and the scalloped hem, in producing the scalloped hems in a known manner, and in heating the ribbon to the melting temperature of the thermofusible yarn.

Patent FR-2580889-A1 (FR)
Title: Method of creating a plasma by combustion of a gas or a vapour by means of a high electrostatic voltage.
IPC: H05H1/24
Filed: 1985-04-18
Abstract: The invention relates to a method designed to obtain a reaction due to the creation of electrostatic high-voltage energy through friction of a gas or a vapour under pressure. This high voltage thus created will allow the kindling and combustion of the gases having served in its creation, thus producing a plasma. An illustrative implementation of the method consists of an insulating tube 1 containing an entrance orifice 2 and an exit orifice 3; hollow metal cylindrical pieces 4 are placed alternately with insulating pieces 5 in the tube. A pressurised vapour is introduced into the entrance 2, flows through the tube inside the pieces 4 and 5; the friction creates electrostatic charges which accumulate around the orifice 3 of the tube, causing the combustion of the vapour escaping therefrom. The method can be used in rockets or similar propulsion, in heat engines or for heating up water, the vapour from which can be used in turn as a source of energy.

Abstract: The thyroid hormones to which the method applies are present in free form in a sample. 
<??>The method consists in allowing T3 and/or T4, to be assayed, to compete with thyroglobulin for the sites of anti-T3 and/or anti-T4 antibodies present in a limited quantity, and in then determining either the quantity of thyroglobulin bound to the anti-T3 and/or anti-T4 antibodies or the quantity of thyroglobulin not bound to the anti-T3 and/or anti-T4 antibodies. The thyroglobulin is generally immobilised on a solid support. The anti-T3 or anti-T4 antibodies may be labelled directly, for example with a radioactive, fluorescent or luminescent component or an enzyme, or alternatively be visualised indirectly with other labelled antibodies. 
<??>This method may be used for determining the total T3 and/or T4 in a biological sample, provided an inhibitory component is added to the sample to liberate the T3 and/or T4 bound to carrier proteins.
