Abstract: An electronic circuit board (l0l, l02) electrically connected to a bus (l50), may be removed and re-inserted in the system without the necessity of disabling other circuits connected to the bus (l50). A latch actuated switch (ll3) provides a control signal in anticipation of circuit board insertion or removal. The control signal activates a control circuit (l20) which seizes control of the bus after completion of other bus communications and stops the generation of clock pulses normally required in transmission of signals on the bus (l50). When the other bus communications have ceased, the control circuit (l20) controls power supply circuitry (l05) to remove power from the board (l0l, l02). When insertion of removal of the board (l0l, l02) is complete, the control circuit (l20) will restore the bus clock pulses and relinquish control of the bus.

Abstract: The method according to the invention allows the production of patch-rubbers intended to repair radial-ply and bias-ply tires. Said patch-rubbers, while showing the same strength as the nowadays known, are more flexible and do not affect the original mechanical features and performances of the regions of the tires having been repaired therewith. The patch-rubbers obtained by implementing the method are also suitable to perform retreading operations on tires by means of both high pressure molding machines and autoclaves. The method essentially consists in inclining, in respect of the longitudinal or symmetry axes of the patch-rubbers, alternatively in the clockwise and in the counterclockwise direction, the cords made of a fibre and embedded into each one ply of a plurality of superposed plies, and in superposing to said plies, having said cords made of a fibre embedded therein, a further ply of smaller area having rectilinear metallic or fibre cords embedded therein; said further ply being so positioned that, when the patch-rubber is applied to the tire to be repaired, said metallic or fibre cords either match the direction of the radial metallic cords forming the casing of radial-ply tires in the sidewalls and in the tread respectively, or form a given angle with the direction of the biased metallic cords forming the casing of bias-ply tires.

Abstract: A switching system for switching synchronous and/or synchronous data blocks between incoming and outgoing multiplexes. The asynchronous blocks are sporadically carried in the multiplexes. The cost of the system is reduced owing to the use of a single buffer memory whose cells memorize indifferently synchronous and asynchronous blocks. The number of cells is lower than the product of the number of incoming or outgoing multiplexes and the number of blocks per frame in the multiplexes. A buffer memory managing and write addressing circuit derives and memorizes the occupied or free condition of each of the buffer memory cells thereby permanently selecting the address of one of free buffer cells in which a data block is to be written. The occupied condition of a cell is signalled responsive to the write of an incoming data block into this cell, and the free condition of the cell is signalled responsive to the last read of the written block. A written block may be read several times when it should be transmitted onto several addressee outgoing multiplexes.

Abstract: A method of selectively incrementing and decrementing the decimal values of digital filter tap coefficients is disclosed. Each tap coefficient is represented by a plurality of cannonic signed digit (CSD) encoded "nibbles". The combined CSD-encoded values of the individual nibbles bear no direct relationship to the decimal-valued tap coefficient, the range of each nibble is restricted to allow such a direction relationship. Each CSD-encoded value is adjusted by incrementing, decrementing or placement at an endpoint of its range and direction reversed, whereby the resulting decimal value will be incremented or decremented. The sign and direction of movement within the range of each nibble is readily ascertained by reference to a set of simple rules.
