Title: Assembly installation using circulating pallets - uses coding system to control movement of pallets which are frictionally advanced by conveyor belt
IPC: B23Q7/14
Filed: 1980-10-14
Abstract: The method of assembling mechanisms etc. in a workshop uses a system of manual work stations using benches constructed so that they can be assembled in a flexible manner. These are combined with a conveyor used to advance pallets between the stations so that components can be added to the mechanisms. The pallet is advanced by the belt along one edge, and is rectangular, designed so that it can be advanced by either long edge. The belt has strands at right-angles to each other and is driven by an electric motor. A pallet can be driven frictionally, and can carry a mechanical coding. It can carry a strip with a higher coefficient of friction than the remainder of its body. It can incorporate projections which are used to change its direction.

Title: Laying of pipes in weak or loose earth - where trench dug in earth is filled with cement:bentonite mixt., which is drilled to form hole for pipeline
Inventor: JOST JEAN
IPC: E21B7/04
Filed: 1981-04-14
Abstract: A trench is dug in the earth, and is filled with a mixt.(a) of cement and bentonite. Before mixt.(a) has set, a guide wire or tube is located in a straight line, and at a specific height, in mixt. (a). The guide wire or tube is clamped at both ends so it is firmly held in a desired position. The mixt.(a) has adequate strength, but is sufficiently soft so that after setting, it can easily be drilled to make a hole or channel. The guide wire or tube is used in conjunction with the drill, so a straight hole is obtd.; and then pipes joined end to end are fed through the hole to make a pipeline. The guide wire or tube pref. has the same density as mixt.(a) so it neither rises nor sinks in the mixt. Process is used esp. for laying large dia. sewage pipes, where a straight pipeline at a specific height can be obtd.

Title: Flowmeter to measure flow-rate of waterway - uses displacement of screen having only one degree of freedom and formed from two plates and intermediate section
Inventor: COMBES GILLES
IPC: G01F1/38
Filed: 1981-05-15
Abstract: The flowmeter contains a mobile screen (3) which extends over almost the entire width of the waterway and over part of the waterway's depth. The screen is mounted such that it has only one degree of freedom. The screen's position is due to the combined effects of its weight, a counterweight, the hydraulic forces and the connecting devices. The displacement of the screen according to its degree of freedom is a function of the flow rate only. The screen is formed by two plates (3A,3B) interconnected by an intermediate plate (3C). The shape of these plates (3A,3B) is such that the resultant of the hydraulic forces applied on them, excluding the intermediate part, is zero.

Title: Aseptic coupling for medical pipes esp. in peritoneal dialysis - has disinfectant pad in one half-coupling through which mating surface is advanced
Inventor: LOPEZ GEORGES
IPC: A61M39/16
Filed: 1981-05-19
Abstract: The coupling comprises male and female half-couplings. The female half-coupling is entered via a counter-bore leading to a coaxial, conical seating. The male half-coupling body can be secured coaxially, rapidly and rigidly to the female half-coupling. The male half-coupling contains an axially movable, rigid tube which has a closed, pointed end leading a conical surface formed to mate with the surface of the seating. In front of the leading end of the tube, the male half-coupling body houses a flexible, absorbent pad which is satd. with disinfectant. The male body is pref. equipped with a coaxial, rotary nut which can screw forward the rigid tube so that the leading end passes through the disinfectant pad and is then clamped against the seating. The coupling has two halves, each connected to a flexible pipe in a medical circuit, e.g. a pipe leading to a catheter or to a supply of medical soln. The coupling can be frequently disconnected and reconnected without loss of asepsis. This is vital in the case, e.g., of peritoneal dialysis for kidney patients for the prevention of peritonitis etc.

Title: Magnetic field perturbation compensating system for aircraft - analyses development of modulus of earth field perturbed in space to transform ellipsoidal theoretical sphere
Inventor: MONNET LOUIS DEDREUIL
IPC: G01C17/38
Filed: 1981-06-11
Abstract: The device contains a magnetometer which give electrical signals proportional to the components of the perturbed magnetic field. A processor calculates directly the coefficients used to correct the data delivered by the magnetometer without needing to compare with a known head. The earth's field modulus is considered as constant between two successive measurements. The evolution of this modulus perturbed in the space is observed. The compensation coefficients, iteratively calculated, permit the evaluation of this modulus to be converted from an ellipsoid to a theoretical sphere centered on the magnetometer axis in order to define the correspondence between the perturbed measurements and the real measurements. The tensor expressing the induced fields in considered symmetric.

Title: Laser optical safety device for folding press - uses laser beam above level of workpiece to detect hand under jaws of press and accordingly invoke emergency stop
Inventor: CROGUENNEC JEAN
IPC: F16P3/14
Filed: 1981-08-06
Abstract: The arrangement provides emergency stop of machinery such as folding presses if a hand is between the jaws. An optical system is used, having a light beam (5) emitted by a source (7) and received by a detector (8) placed on either side of the jaws (1,2) of the press. The light beam is formed by a laser positioned vertically so the beam is below the rest position of the upper jaw (2) but above the level of the work (6) when it is placed on the lower jaw (1). The height (d) of the beam above the workpiece is such that it will detect a human finger resting on the workpiece. The light beam is detected and amplified to supply a relay which holds off the emergency stop mechanism. If the beam is interrupted while an operating stroke is requested the relay is released and the emergency stop activated.

Patent FR-2519134-A1 (FR)
Inventor: BILLARD ALAIN
IPC: H01Q15/18
Filed: 1981-12-30
Abstract: A rope is pulled between an end member such as a parachute forming a sail with regard to the wind and a main floating anchor located at the other end. This rope is connected at chosen intervals to captive-balloons, each associated with secondary floating anchors. The captive-balloons are chosen to be sensitive to the wind in order to incline themselves with respect to the floating anchor and to respectively support decoys formed by sets of retroreflective trihedrons. Advantageously, the decoys are individually connected in their lower part to floating bodies such as slightly inflated and loaded balloons. The invention has application, in particular, to the simulation of large surface ships.
