    摘要: An arrangement for the dry reconditioning of used foundry sands in which used sand is fluidized with air or an air/gas mixture and flung against a precipitator to separate and remove substances covering sand particles. The precipitator has several planar baffle elements arranged in concentric circles around a conical deflector. A jet of used sand/air directed toward the deflector expands radially outwardly toward the baffle elements so that the jet is decelerated several times by the deflector and the baffle elements and, in a confined space, split into individual streams and swirled to provide heavy mechanical friction between sand particles and between sand particles and the baffle elements.

    摘要: A gear-shift mechanism for motor-vehicle multi-step transmissions with interruption of traction is designed in the manner of a semi-automatic transmission. Manual control switched 80, 81 connected to a control unit 82 serve to actuate shift forks via servo systems 90. Sensors coact with rotating marks on the power take-off shaft and with marks on the speed gears which are driven by the drive shaft. The relative phase position .phi. between the speed gears and the gearshift sleeves driven by the power take-off shaft is determined by a phase detector 75. When a pre-determined phase position is reached, these elements are brought into engagement with each other.

    摘要: A transverse force rod having at least one bearing cage disposed on both sides of a joint. Each bearing cage has a front plate and a trapezoidally shaped steel strip which is welded to the front plate. The transverse force rod is fixedly supported in one bearing cage, and a transverse force rod bearing sleeve is fixedly supported in the front plate of another bearing cage. The transverse force rod or the transverse force rod bearing sleeve penetrates the front plate and the steel strip of the one bearing cage or the other bearing cage.

    摘要: In a synchronizing mechanism for clutches, there are provided between the gear shift sleeve and the synchronizing ring (14,15) stop bodies in the form of dogs (25, 26) which are in contact with the gear shift sleeve (between the teeth 34) in the circumferential direction by form-locking engagement and in the axial direction through spring-loaded stop balls (21) and in the neutral position are spaced from the synchronizing ring by a distance substantially equal to the axial extension of the check faces (32, 33) between the gear shift sleeve and the synchronizing ring. In this manner it is ensured that during shifting the axial force previously exerted through the check faces (32, 33) on the synchronizing ring (for instance 15) is replaced by an axial force which is transmitted by the dog and which prevents the synchronizing ring from coming off the countercone before the form-locking connection between the gear shift sleeve and the clutch body is established.
