Abstract: A connector tip is fixed to one end of an optical cable of a bundle of fibers surrounded by an outer protector sheath constituted by a thermoplastic material, the tip being also constituted by a thermoplastic material heat-weldable with that of the outer sheath. The sheath is removed in the vicinity of said end, the tip is placed in position on this end so that it surrounds and is in contact with, a zone of the cable stripped of its outer sheath and with a zone of the cable provided with its outer sheath and adjacent to said stripped zone.

Abstract: A flowmeter-volumeter of the type which counts the revolutions of a mobile body in a revolution channel into which open a fluid inlet passage and a fluid exhaust passage. The device includes a first flange grooved with a revolution groove which is a first portion of the channel and grooved with one of both said passages, and a second flange grooved with a revolution groove which is a second portion of the channel and grooved with the other one one of the passages. Both flanges are connected by fastening means arranged for allowing a rotation displacement relative to each other, in order to be able to adjust the distance between the openings through which both passages open into the channel. The device is used to measure flow of a fluid.

Abstract: The invention relates to an union assembly for electric cables, inter alia electric cables which experience very high pressures, and adapted to be interposed between a connector element and the cable extending thereto, an insulant filing the inner chamber in which the sheathed cable conductors are connected to the corresponding elements or contact tags or posts of the connector. In said union assembly, the insulant takes the form of a resilient agent in which the conductors are embedded and which experiences via the union assembly outer wall the external pressure acting on the union.

Abstract: The invention concerns connectors, more especially these, miniaturized or not, comprising a large number of contacts, with means, controlled by a locking ring, adapted to cause interpenetration of the contact pins into the corresponding sockets, after the two male and female parts have been suitably presented opposite one another by suitable grooves. According to said invention, means are provided which towards the end of the mechanical locking process, enable the contact pressure between pins and sockets to be increased, these means being for example manoeuvrable by complementary rotation in the mechanical locking ring.
