Abstract: A multipolar electrical connector with spring contacts has, for each conductor to be joined to the connector, a first substantially cylindrical aperture adapted to receive the conductor and a second aperture, parallel to the first aperture, adapted to receive an actuator pin which, sliding in the second aperture, according to its position acts on a spring contact of the connector to lock the conductor to the connector or to release it from the connector. When the conductor is blocked in the connector by the spring contact, the actuator pin is inserted completely into the connector.

Abstract: An electrical connector element (1) includes a connector body (2) wherein contact housings (20) are formed, electrical contacts (4) crimped to respective electrical cables (8) and able to be housed in the contact housings (20) of the connector body (2) and locking elements (5) designed to be fixed in the connector body (2) after insertion of the contacts (4). The locking elements (5) include stops (55), which protrude into the contact housings (20) so as to prevent the contacts (4) from coming out of their housings.

Abstract: An electric motor, comprising a shell for a rotor, which is closed by a cover provided with a hole for the passage of a motor shaft; the cover accommodates and supports sliding contact brushes for a commutator for supplying power to the rotor, a sensor for detecting the rotation rate of the rotor, and connections for signal transmission and power supply of the sensor. The sensor and its connections for the transmission of its signals and for supplying it with power are accommodated in a receptacle, which in turn is then inserted in a complementarily shaped seat in the cover.

Abstract: A standard type electrical connector element (1; 100; 200; 300), with a square cross-section measuring about 21×21 mm, includes (2; 102; 202; 302) within which are formed seats (22) adapted to house contacts (4; 204) adapted to receive the conductors (50) of electrical feed cables; a seat (23) adapted to house a contact (6; 106; 206; 306) adapted to go into contact with the conductor of an electrical earth cable, a cover (8; 108) which can be coupled on the body and which is provided with holes (83, 82) disposed in register with the contacts (4; 204) to allow the conductors of the feed and earth cables to be inserted, and spring elements (7) disposed in the seats (22, 23) of the body in which the contacts are housed to clamp the conductors of the electrical cables in contact with the respective contacts.

Abstract: A process for baking electrically conductive wires clad in insulating plastics resin, comprising a first, evaporation stage for evaporation of solvents and a second resin polymerization and cross-linking stage, which are performed respectively in a first and in a second region of a tunnel chamber in a continuous oven between the inlet regions and outlet regions of which the wires advance, a third stage comprising aspiration from the oven of a mixture of air and solvents formed during the first evaporation stage, and a fourth stage comprising heating this mixture to a predetermined temperature such as to cause combustion of the solvents, and including a fifth stage of introducing heat energy to these regions of the oven from at least part of the stream of air and combustion products coming from the fourth stage, through heat exchangers disposed on the outer surface of this tunnel chamber, in such a way as significantly to reduce the introduction of heat energy provided to the chamber by heating means supplied

Abstract: A furnace for firing an enamel-insulated wire comprising a principal cham, an auxiliary unit for withdrawing a first stream of air and solvent vapors from this principal chamber for effecting combustion of the vapors themselves. A part of a second stream leaving the auxiliary unit is mixed with a volume of air at ambient temperature and passed to the principal chamber; another part is sent to a heat exchanger in which it gives up part of its thermal energy to a second volume of air at ambient temperature which is heated and introduced into the principal chamber.

Abstract: A furnace for firing electrically conductive wires clad with an insulating lastics resin, comprising a principal chamber defining a first portion in which evaporation of solvents from the resin takes place and a second portion in which this resin is polymerized and cross linked, and a diffuser element provided with separator means operable to divide the gas stream into a plurality of partial streams and means for distribution and introduction of these partial streams into a peripheral zone of the first portion in a direction substantially parallel to the lateral surface of the first portion itself.

Abstract: In a cartoning machine which wraps cartons about preformed blocks of objects, it is proposed to insert a new carton one after the other into the block feed line before the preceding carton has left the insertion zone, with temporary partial overlap of the cartons, so as to reduce the distance between the successive fed blocks. Furthermore, in the insertion station, the blocks of objects are fed by transverse bars carried in a projecting manner from a chain conveyor disposed entirely on that side of the feed line opposite the side from which the cartons are inserted.
