Title: Method and device for acquisition of seismic data from a repeating source and several receivers
Inventor: NAVILLE CHARLES
IPC: G01V1/00
Filed: 1987-08-05
Abstract: The invention relates to a method and a device for acquisition of seismic data. A repeating source S and several receivers Rk are placed in a seismic-wave emission zone and in a reception zone respectively. The receivers Rk are interconnected in a network RE. Prior to emission of each incident seismic pulse Ij, the network RE is configured so as to interconnect each receiver Rk in series, with the possibility of programming the connection polarity of each receiver. The network RE delivers at the output a resultant signal VSj for each incident seismic wave pulse Ij, this resultant signal corresponding to a linear combination of the signals Sjk delivered by each receiver Rk. The operations of emitting and recording the resultant signal are repeated a number m of times greater than the number of receivers Rk, so as to configure the constituted network RE in a different manner. The signature of each signal Sjk delivered by each receiver Rk is obtained by a linear combination of the values of each of the resultant signals VSj. Application to picking up seismic prospecting signals.

Title: Device for wrapping products in packets with label
Inventor: RUPPEL REMY
IPC: B65C1/02
Filed: 1988-04-07
Abstract: The device for wrapping products, such as packets of paper handkerchiefs, in packets with label, having a means for converying a strip (11) of flexible material, cutting it into sheets and wrapping the products in the sheets, and a means for depositing the labels at regular intervals on the strip is characterized in that it has a cutting mechanism (27) co-operating with a transfer mechanism (28) for cutting the labels from an ribbon (21) with adhesive applied to one surface and placing the said labels on the moving strip (11). The invention is applied in particular to the adhesive strips for affixing the flaps of packets of paper handkerchiefs. A strip of flexible material such as polyethylene is previously marked with a discontinuous cutting line which traces the outline of the flap, the adhesive strips are laid on the strip acrossthe flaps, and then the film is cut, transversally to its direction of motion into individual sheets (3) in which the packets (2) are wrapped.
Patent FR-2626241-A1 (FR)
Title: Improved ballasted craft with sail propulsion
IPC: B63B39/02
Filed: 1988-01-21
Abstract: Improved ballasted craft with sail propulsion characterised by the possibility of adjusting the limiting angle of list of the float as desired, and of automatically triggering, at a predetermined angle in the event of there being a risk of capsizing, its return to safety through reverse list. Operation: the mast swivels, provided with a locking member, against a vertical semi-circular hoop connected to the hull, carrying limiting stop pieces. As soon as the boat leaves its position of stability and the mast inclines, it encounters the locking stop piece of the hoop at 20 DEG and the float henceforth follows it in a listing movement. This list may be interrupted when it is considered dangerous at the capsizing limit. In order to do that a ballasted balance whose balance arm always stays in the horizontal position sets off a contact, by means of an adjustable thrust cylinder, switching on an electromechanical or pneumatic pulsing member which throws the bolt. Thenceforth, the released float moves back in a reverse safety list limited by the adjustable stop piece and its list passes from 45 DEG to 30 DEG . Thus, automatically, with the safety feature of an electrical circuit breaker, any risk of capsizing may be precluded.

Title: Fibre-optic rotary switch
Inventor: MORILLON PIERRE CHARLES
IPC: G02B6/38
Filed: 1988-07-05
Abstract: The switch comprises a rotary drum 1 supporting a first optical fibre F1 and a stationary drum 2 supporting second optical fibres F2. End faces of the fibres are arranged in a substantially coplanar manner on facing diametral faces 10, 20 of the drums, these faces being respectively substantially equal and disjoint. The rotary drum 1 is precisely aligned with the stationary drum 2 by virtue of a longitudinal rolling ball bearing 32, 33 and of a radial ball thrust bearing 34 central to the facing faces. A flexible coupling, by means of a bellows 50, removes the constraint of the required accuracy of alignment of the drums in relation to the clearances (movements) of a drive shaft 40. The shaft is driven by a DC motor associated with a memory containing the precise angular positions of the second fibres F2 relative to the first fibre F1 and corresponding to optimal couplings.
