Date Aug. 15, 1985.A method for providing and for testing adaptive echo cancellation in an apparatus including transmission equipment for data communication. The apparatus includes a 2-wire to 4-wire hybrid circuit which receives a signal from a remote end which is cut off for purposes of the testing method. A signal consisting of randomly occurring ones and zeros is applied to the send end of the apparatus. Also included in the apparatus is an adaptive echo canceller which cooperates with the send end and with a filtered signal received from the hybrid circuit to produce a correction signal which is fed back to the adaptive echo canceller and which is also compared with threshold values for purposes of testing the function of the apparatus.

Abstract: In a motor-driven two-wheel vehicle, especially a motorcycle, whose frame (2) on each side has a foot rail smith (16) that swings out against spring resistance, there is a gearbox (26) as well as a disc break (21) controllable by means of a foot break pedal (17). So that the foot rail smith can, upon need, without engagement in the other control mechanisms, in the absence of costly automatic gearbox, and with use of a standard gearbox, easily be able to be mounted and removed, and to facilitate shifting between different gears without use of the feet and to ensure control of the foot break even when the vehicle is used for travelling over terrain, the gear box is in a particular known way able to be switched from foot shifting and/or hand shifting. By a cable transfer (24) or similar device the disc break (21) is extra-controllable by a further foot break pedal (23) with a foot rail smith (16) preferably coupled with the foot break pedal (17).<IMAGE>

Abstract: The chair comprises a base 1, optionally provided with castors 2, carrying pneumatic height adjustment means in the form of a pneumatic piston-and-cylinder arrangement (3). A U-shaped frame member 6 is mounted on one end of the piston 3a, which frame member supports the chair arms 7 at its extremities. The back portion 8 of the chair is hingedly connected to the posterior extremities of these chair arms and the lower region of the back is hingedly connected to the seat portion 10. The seat portion is capable of longitudinal movement due to its mounting on sliding guides 12, 13 mounted on the central portion of the U-shaped frame 6. Accordingly, any change in the angle inclination of the back portion is associated with a corresponding movement of the seat portion so that the centre of gravity of the chair remains substantially stationary.

Abstract: An asynchronous interrupt arbitrator buffers the occurrences of multiple interrupts so as to permit an asynchronous host to reliably determine which interrupt request lines have been activated. The technique responds to activities on any interrupt request line, but multiple requests on the same line between host responses may not be enumerated. An arbitration circuit and a buffering scheme eliminate the possibility of missed interrupt requests or erroneous multiple triggering of a single request event. In a particular embodiment, a source of interrupts is synchronized to a clock ICLK. The host processing element asynchronously responds to interrupt requests by sensing an interrupt request signal and then reading a status register 44, 46, 48 to identify the source of the interrupt request. <IMAGE>

Abstract: An arrangement for ejecting objects from a projectile, includes a hollow projectile body having a nose end with a plurality of objects disposed in a column within the projectile body. An ejection charge is disposed within the projectile body at the nose end. An ejection device including a hood enclosing a cavity is ejectably disposed within the projectile body between the ejection charge and the column. The hood has a wall with an opening facing the ejection charge so that, after ignition of the ejection charge, resulting powder gases enter into the cavity through the opening to generate a gas pressure between the hood and the adjacent object and simultaneously exert a force on an exterior portion of the wall of the hood that causes the hood and the column to be ejected from the tail end of the projectile body, whereby the hood separates from the column once the hood and column are free of the projectile due to the pressure in the cavity.
