Title: Method and device for treating drilling products
Inventor: ALAIN MORIZOT
IPC: E21B21/015
Filed: 1990-09-26
Abstract: A treating device (34) is placed around the drilling instrument (17), which device rests on the ground around the drilling orifice and collects the particles and debris released by the drilling, possibly conveyed by a carrier gas injected at the bottom of the bore hole through the end of the drilling instrument (17). A humidified gas is injected through a connector (54) into an annular prechamber (52), which gas penetrates via inlets (56) into a cyclone-effect chamber (36) surrounding the drilling instrument (17), which can slide and turn in a leaktight manner through an upper wall of the device. The humidified gas agglomerates and weights the particles, in particular the finest particles, and the mixture thus treated leaves the device through an outlet connector (59) to be deposited at a suitable place or in a suitable container. Use for avoiding the formation of dust in the surroundings of a work site.

Patent FR-2677135-A1 (FR)
Inventor: PIERRE JEUCH
IPC: H04B1/59
Filed: 1991-05-28
Abstract: The invention relates to interrogator E/R (emitters/receivers) means, or portal structure associated with responder E/R means, or tag, comprising a digital code for identification. The portal structure sends four types of information in the form of signals to the tags which respond by "yes" or by an absence of response till the portal structure has found their code. When its code has been found, the tag inhibits itself, thereby enabling the detection of other codes. The invention applies particularly to the surveillance of individuals carrying responder E/R means or to the cashing and billing of goods sold in large stores.
