Abstract:
A robot intended to the assembly of constitutive parts of objects comprises at least one working head (4) provided with a tool (8) effecting above a working area (9) motions controlled by a program according to at least three degrees of freedom and, within said working area (9), a device (14) providing for the accurate positioning of the parts to be manipulated in predetermined positions and orientations. It is characterized in that it comprises at least one removable preformed receptacle (17) providing for the collective transport of parts to be assembled to or from the working area (9), said receptacle being configured to maintain with a certain tolerance said parts in relative positions and orientations similar to those determined by the device (14) and arranged to cooperate with the latter. Assembly process implementing a robot such as hereabove defined and its application to the assembly in series of constitutive parts of objects.
Abstract:
The invention relates to a method and apparatus for handling drilling mud containing oil/water emulsion, comprising the step of decomposing the emulsion content of the mud, separating phases thus obtained, and establishing said decomposition between electrodes powered by at least the limit voltage of stability the emulsion, so that determining experimentally the level of the voltage of stability, type of voltage and residence time, then settling the solid phase of the decomposed emulsion content of the mud into a slurry, and separating the liquid phase containing macroscopic oil and water phase elements created during settling. The apparatus (A) according to the invention contains a mixing and storing unit (A1) for drill-cuttings connected to a homogenizing unit, and an emulsion decomposing unit (3) provided by positive "and negative electrodes alternating in a vertical arrangement; and a gas outlet arranged on the top of the emulsion decomposing unit (3).
Abstract:
The installation according to the invention comprises a network of rails of which all the sections are power-supplied to the same potential and an assembly of pallets intended to circulate throuout said network. Each pallet (10) comprises a platform (11) fitted with four boggies (12) driven by at least one electric motor (13). Each pallet comprises a control unit (15) which includes its intelligence and which controls an anticollision device (18) of the elements (16 and 17) arranged to tap off the electric power vehicled by the network, and a sensor (19) which detects the presence or the absence of an external signal emitted by a node of the network.
Abstract:
The installation comprises at least an autonomous pallet (10) carrying driving means, preferably in the form of electric brake-motor (14), said pallet being provided with wheels (15, 16, 30, 31) to circulate on a network of rails conducting the supply current of the motor and the control signals for the driving means of the pallet. The pallet comprises two beams (11 and 12) and a plate (13) provided with two centering pins (21). The installation is convenient in that it is flexible and may be adapted to all utilizations, particularly because the pallets may be processed individually by a central data processing unit.
Abstract:
Sealed package and method for producing said package which is substantially comprised of a container (1) and a cover (2) adjusted to the container. The container comprises a flange (3) provided with a lip (9) orientated downwardly of the container. The cover comprises a flange (6) provided with a lip (8). Both lips (8 and 9) have each an outer cylindrical surface which is orientated in the prolongation of each other. A flexible seal tape (13) is welded or glued against both cylindrical surfaces to hold the cover (2) and the container (1) together. This package is particularly appropriate to hold food products such as beverages, prepared or precooked meals or sterile or aseptized substances.
Abstract:
The robot comprises at least one holder (10) for the parts (11) in an assembly area and a head (1) carrying the assembly tool (31). The head is translatingly and/or rotationally movable with respect to the part holder by means of guiding supports (3) and is positioned by motors (6). The head carries in a fixed or sliding mode a device (20) enabling to apply the tool (21) to a part (11) with a predetermined force. The robot further comprises at least one platform (15) facing the holder so that the head (1) is located between the platform and the part holder. The platform (15) is mechanically connected to the part holder by rigid elements (5) arranged outside the space between the assembly area and the platform so as to resist a force tending to take the platform away from the holder.
