IPC: H01P1/30
Filed: 1981-01-13
Granted: 1983-02-18
Abstract: In a method for fixing a ferrite to a metal piece such as a pole-piece of a magnetic polarizing circuit of a microwave device, a first step consists in depositing a nonresistive metal on the ferrite face to be fixed. A second step consists in applying a very thin layer of heat-conducting adhesive on the metallized ferrite face and bonding the ferrite to the metal piece, thus ensuring low thermal resistance, very low insertion loss and high power capability.

Abstract: An apparatus for manufacturing molecularly oriented plastics pipes includes a tubular mould of transverse dimensions equal to those of the pipe to be produced and equipped with a device for admitting a fluid under pressure into a region intended to receive the pipe section to be expanded, a member for closing and grasping one end of the pipe section of a tubular sleeve which opens into the mould by an end away from the closing and grasping member and the transverse dimensions of which correspond to those of the pipe section and a means for causing a controlled relative axial displacement of the sleeve in relation to the closing and grasping member in which the open end of the sleeve is equipped with an annular plunger incorporating a surface of a frustoconical shape extending towards the inner wall of the mould and widened out in a direction away from the closing and grasping member. The apparatus makes it possible to produce pipe sections which are molecularly oriented in a perfectly reproducible manner and which are especially suitable for the construction of pipelines for fluids under pressure.

Abstract: Insulating equipment (100) includes a flexible arm (1) having at one of its ends a means for attachment to a pole and at the other end means for attaching an electric line substantially perpendicular to the arm (1). The thickness of the arm (1) decreases regularly from the means fo attachment to the pole toward the means of attachment to the electric line, while the height of the cross section of the arm is constant. The arm (1) has in the direction of its thickness a series of layers (7a, 7b, 7c, 7d) of continuous mineral fibers extending in the direction of the arm's length and separated by layers (8a, 8b, 8c, 8d) of randomly-oriented short mineral fibers. These layers are bonded by a synthetic resin in which a layer (9a, 9b) of fabric of mineral fibers may be placed on each side of the arm (1) between the first layer of short fibers and the following layer of continuous fibers. To be used for improving longitudinal flexibility and resistance to vertical loads.
