Abstract: An embossing device comprises a first embossing roller and a second embossing roller forming a passage for a strip of wrapping material to be embossed; the first embossing roller comprises on its surface a tooth set to imprint a pattern and an imprinting system to imprint a reference on the strip to identify a section of the strip: the imprinting system comprises an area without teeth in the tooth set, extending along a sheaf of directrices of the first roller for forming on the strip a non-embossed band in the pattern; the imprinting system comprises a second tooth set lying on the sheaf of directrices to imprint an embossed mark on the strip in the non-embossed band.

Abstract: A wrapping wheel forming part of a cigarette packer is equipped with at least one conveying head that presents a pocket and is carried by the wheel along a feed path, passing through a first station at which a product is directed into the pocket, then through a second station at which a leaf of wrapping material is laid over the pocket and pinned in a predetermined position by pivoted grippers, and finally through an outfeed station where the product is ejected from the pocket, paired with the wrapping leaf and transferred together with the leaf to a further wrapping wheel; the grippers are operated by direct interaction with suitable transmission and shifter components positioned outside the peripheral compass of the wrapping wheel.

Abstract: A method and an electronic apparatus for reversing the rotation of a two-stroke internal combustion engine, provided with an ignition system powered by a permanent magnet voltage generator. The electronic apparatus comprises a microprocessor control unit programmed for controlling the sparking both during forward and backward rotations, and for controlling the reversal rotation procedure of the engine. The reversal procedure is controlled on the basis of information obtained from a first binary signal emitted by a bistable magnetic sensor activated by the magnetic flux of the generator, and from a second binary signal correlated to the polarities of output voltage of the voltage generator. The original forward or backward rotation is made to reverse by providing a sparking delay, and subsequently generating an advanced spark while the engine is still rotating in the original direction.

Abstract: In a packaging machine that includes a wrapping wheel equipped with at least one conveying head affording a seat capable of movement with the wrapping wheel along a looped path, the head is indexed through a first station at which the seat receives a product, a second station where a wrapping sheet is taken up and held stably by a gripper mechanism across an opening of the seat, in a predetermined position, and an outfeed station at which the product is ejected from the seat and caused to associate with the wrapping sheet, whereupon product and sheet are transferred together to a further wrapping wheel; the machine is equipped with a device located externally of the wrapping wheel by means of which to actuate the gripper mechanism.

Abstract: An electronic ignition and alarm system for motorcycles. An electronic circuit for reading a coded signal emitted by a code-generating integrated circuit inside the ignition key, can be connected inductively or by electric contact means to a microcontroller programmed to enabling the operation of the ignition circuit of the engine after identification of the coded-signal. The coded-signal reader and the microcontroller are fed by a power source comprising a capacitor for storing the energy supplied by the voltage generator of the ignition circuit of the motorcycle.

Abstract: An electronic ignition system for reversible internal combustion engines. The ignition system comprises a voltage generator (10, 11) for feeding the ignition circuit (12, 13) of the engine (P), a first signal pickup device (PK1) in the voltage generator (10, 11) for providing a first timing signal and a second signal pickup device (PK2) angularly spaced part in advance for providing a second timing signal to a microprocessor (18) operable to detect the direction and the speed of rotation of the engine, and to generate control signals for sparking during forward or reverse running, depending on timing information provided to the microprocessor (18) by the first and second signal pickup devices (PK1, PK2). Reversal of rotation is started by providing the microprocessor (18) with a reverse control signal by a manually actuable switch device.
