Abstract: ABSTRACT OF THE DISCLOSURE         In an ignition system for internal combustion engines having a magneto generator for charging a capacitor and a thyristor for discharging the capacitor through an ignition coil upon receiving an ignition signal, an auxiliary capacitor and an associated trans-former are provided as a source of the ignition signal.          The auxiliary capacitor is charged through the transformer by each half-cycle of the magneto generator output of the opposite polarity with respect to the charging half-cycle of the capacitor.  The auxitiary capacitor is discharged through the gate-cathode path of the thyristor under control of an auxiliary switching element to which a timing signal generator provides a timing signal at a proper ignition time.  Since a short circuiting switch-ing element connected accross the auxiliary capacitor has the control electrode connected to receive through a resistor each half-cycle of the magneto generator output following the half-cycle of the magneto generator output during which the auxiliary capacitor is charged, if no timing signal has been applied to the auxiliary switching element the auxiliary capacitor will necessarily be short circuited.  When the engine is rotating in the normal direction, the timing signal is only required to be generated during a time period from the completion of charging of the auxiliary capacitor until the short-circuiting switching element is turned on and this allows a sufficient range of davance angle.   In the reverse rotation of the engine, the auxiliary capacitor is short circuited before the timing generator generate the timing signal resulting in the termination of the reverse rotation.

Abstract: ABSTRACT A HEAT-RECOVERABLE SLEEVE FOR ENCLOSING SPLICES IN PRESSURISED CABLES A heat-recoverable sleeve for enclosing splices or joints in pressur-ised cables or supply lines is given increased resistance to peeling away from the cable or line by insertion of auxiliary means, preferably a U- or V-shaped flexible strip, which may be heat-recoverable, between the sleeve and the cable or supply line. The ends of the strip are preferably closed and are preferably overlapped and bonded to each other when the strip is placed around the cable or supply line.  A release foil may be positioned inside the U- or V-shape of the strip to resist bonding together of the opposed arms thereof, and the foil may carry adhesive to bond it to one of the arms and may protrude beyond the ends of the arms so that the foil adhesive can help to locate the strip on the cable or supply line.

Abstract: ABSTRACT OF THE DISCLOSURE                      TRANSCEIVER       The transceiver according to the invention is controlled by an automatic alternation device in order to permit the transfert to transmission solely when voice signals are to be transmitted and when the re-ceiver does not receive such signals. On transmission, the transmitter supplies constant amplitude-modulated, high frequency signals during voice activity periods and supplies nothing outside these periods. On reception, detection means for detecting the rapid amplitude tran-sitions of the received signals and a logic circuit control the switching off of an electronic switch during the voice activity periods, so that the output of the receiver only supplies voice signals. A classical voice-noise discriminator validate this decision. The receiver also has an amplifier of the signals received, whose gain is controlled by an automatic control loop. The value of the time constant of this loop is controlled so as to be low during the voice activity periods and high outside these periods.

Abstract: A b s t r a c t A wave motor for propulsion of a floating device, especially a watercraft, comprises a downwards extending supporting structure connected to the craft, and an essentially horizontally disposed, plate-like tilting element which, at a forward portion thereof as viewed in the cruising direction, is pivotally connected to the lower end of the supporting structure, to effect a tilting movement as a result of relative movement between the tilting element and the surrounding water when the craft is floating on the water and is raised and lowered due to wave action, the tilting movement being limited by means arranged on the supporting structure.  The supporting structure is arranged to effect an essentially vertical, relative movement in relation to the craft, and means are pro-vided to keep the supporting structure in an intermediate position and return it to this position when it has been moved away from the intermediate position by influence of wave forces.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention is concerned with a panel assembly including at least two panels and a connector member for mounting the panels to a support surface, the panels being positioned edge-to-edge in coplanar relationship with the respective confronting edges thereof spaced apart, and the connector member between the confronting panel edges and interlocking the panels together by being fixedly secured to the support surface.  Each panel has first and second surfaces lying respectively in first and second parallel planes and has on its respective confronting edge a tongue and a groove, the tongue and groove extending along the panel edge and between the first and second planes, and respectively project-ing and opening outwardly angularly towards the first plane.          The connector member comprises an elongated body filling the space between the confronting panel edges and having on each side thereof a tongue and a groove respectively projecting and opening outwardly angularly towards the second plane; the tongue and groove on either side are complementary to and lockingly engage with the respective groove and tongue on the adjacent respective confronting edges of the panels.  The connector member cooperates with the panels to urge the panels towards one another in tight locking engagement as a result of a compressive force being exerted on the member in a direc-tion towards the support surface when the member is secured to the support surface.  The provision of such connector member does away with the hitherto practice of driving nails or screws in the panel edges to fix the panels to the support surface, while still providing a tight locking engagement between the panels.
