    摘要: In connection with plesiochronous data transmission, data are input into an elastic memory on the basis of a first clock pulse and read out on the basis of a second clock pulse which runs asynchronously with the first. Stuff bits are inserted at the end of a data frame as needed. For this purpose, the phase difference between clock pulses within a data frame is first of all measured. This phase difference is then compared with a threshold and a certain number of stuff bits are correspondingly inserted. In accordance with the invention, a frequency difference existing between the clock pulses is measured and, depending upon in which of several specified segments it lies, a correspondingly predefined modulation curve is used as threshold. Preferably a numerically optimized curve with respect to jitter amplitudes is used for each segment.

    摘要: Depressing the upper case shift key lever pivots a balance beam from a first to a second position, thereby raising the lower case shift lever to an inactive position. When the upper case shift key lever is released, the balance beam is returned to its first position, causing the lower case shift lever to fall to its active position.

    摘要: A mechanism for controlling functions such as step-by-step carriage return, line spacing and rapid carriage return in a typewriter comprises a single cam adapted to oscillate a single actuating member. The actuating member carries a selector which can be positioned to selectively actuate levers controlling the various functions. The selector is positioned by a single lever which is tilted by different amounts by sliding bars each associated with a key corresponding to a given function. In its rest position, said lever locks the actuating member with the cam disengaged from a driving roller.

    摘要: A mechanical continuously variable torque transmission, in particular for flywheel driven, fuel efficient, low emission cars, trucks and locomotives includes structure as follows: three eccentrics 20, 21, 22, mounted on input shaft 18 and carrying needle bearings 23, 24, 25, rotate freely inside three loops of flexible bands 57, 58, 59. One end of each flexible bands is mounted on an oscillating member 36, 37 or 38, which contain overrunning clutches, able to drive output shaft 30. The oscillating members 36, 37, 38 are each held in a home position by a spring 63 and stop 60, 42. The other ends of the flexible bands are each mounted on a pulley 49, 50, or 51, which are themselves mounted on torsion bars 71, 72, 73. The torsion bars are adjustable in angular position as well as in their elastic length. Rotation of pulleys 49, 50, 51 tightens the flexible bands so that rotation of the eccentrics causes torque to the oscillating members and pulleys in the first half of a cycle of rotation of each eccentric. The level of torque is adjustable by changing the elastic length of the torsion bars. The torques exerted on the oscillating members 36 are transmitted through overrunning clutches 39 to the output shaft 30. In a second half of a cycle of rotation of each eccentric, the energy stored in the torsion bars flows back to the input shaft 18.

    摘要: A mechanism for actuating a universal bar of a typewriter from a continuously rotatable drive shaft comprises a principal lever cooperating with the universal bar and carrying a catch able to occupy an active position in the trajectory of a peripheral projection of the drive shaft and a rest position out of this trajectory. The principal lever additinally carries a locking lever cooperating with a control lever of the catch, the latter being connected to the control lever by a spring biasing them relative to one another into an angular position defined by abutments. A fixed stop is disposed in the path along which the control lever moves during an actuating movement of the principal lever in response to engagement of the catch by the projection. When the control lever abuts this stop, it returns to a position for locking the catch while the catch is still in engagement with said projection. Unlocking of the catch to move to its active position is provided by a slide rod having a shoulder for actuating the locking lever. The slide rod can have a second shoulder for permanently unlocking the catch to provide repeated operation of the universal bar.

    摘要: Angular displacements of a rotary member in, for example, a typewriter are controlled by moving a guide roller to shorten and lengthen the path of an elongate flexible member attached at one end to a rotatable stationary pulley and at its other end to an attachment piece, this member being a belt having notched ends one engaging a toothing on a part of the pulley and the other an arcuate toothed segment forming the attachment piece.
