Abstract: The invention contemplates a universal coupling wherein rotatable input and output members are coupled both (1) for universal flexible accommodation of the instantaneous angular orientation (misalignment) of their rotary axes about a single point of axis intersection and (2) for gear-tooth drive engagement in the transmission of torque from one to the other of these members. The result is to achieve both (1) and (2) above (a) for a greater range of axis misalignment than is possible with universal couplings of the past, (b) with greater uniformly high torque transmission as a function of incremental rotation of the coupling members, and (c) with symmetry of torque-transmitting force development with respect to the axes of rotation.

Abstract: Disclosed is a warp knitted narrow lace and method of forming the same in which purls or decorative loops are formed in a curved line along curved scallops of the lace. This warp knitted narrow lace is manufactured by knitting the base fabric into a Raschel lace having a scalloped edge and simultaneously knitting laid in yarns into the edges forming the scalloped edge of the lace in such manner that the laid in yarns are laid in with stitches of soluble yarns and/or ravel yarns located outside base fabric at the outermost portion of the scalloped edge and with stitches of the base fabric in the indentations of the scallops. Dissolving the soluble yarns and/or pulling out the ravel yarns in the area of the outermost edge of the scallops, and cutting the stitches of the base fabric outwards of the purls in the indentations of the scallops results in the formation of a novel lace having purls formed in a curved line along the entire scallops.

Abstract: The invention relates to an eccentric element for generating oscillations in ground vibrators. The eccentric element comprises an eccentric mass (2) radially movable on a rotatable shaft (1). The mass is movable to assume a position displaced in relation to the centerline (15) of the shaft when the shaft (1) is rotated, thus causing the amplitude of the generated oscillation to be changed. To enable control of the amplitude, the eccentric mass (2) is lockable by means of a displaceable locking piston (9) arranged in a recess (16) in the rotating shaft (1). The locking piston (9) can thus assume a position entirely thrust-back into the recess (16), wherein the eccentric mass (2) is released, or a thrust-out position in which the locking piston fixes the eccentric mass (2) in one of its end positions.

Abstract: A torsional oscillation damper for a combustion-engine crankshaft has a relatively light annular disk and a rigid abutment disk which are both centered on and rotatable about an axis. These two disks are spaced axially from each other but are fixed axially and rotationally together. A relatively heavy annular disk also centered on and rotatable about this axis independently of the light and abutment disks lies between these light and abutment disks. An annular soft elastomeric ring is engaged between the light and heavy disks and a ring of friction material is engaged axially with at least one spring between the heavy and the abutment disks. Thus oscillations are damped not only in the elastomeric ring but also by generation of friction between the ring of friction material and either the heavy or abutment disk that it engages.

The pinion is at all times in driving engagement with a gear on the output shaft and is axially movable by a lever to disengage the motor drive so as to allow independent manual operation of the pinion and thereby the output shaft by a handwheel mounted on a shaft. The shaft is drivably coupled with a wormwheel which is in driving engagement with the pinion by means of the driving lugs.

Abstract: In previously known jolt control equipment, it was necessary to know the speed of the turbine of a fluid coupling or hydraulic torque converter driving the automatic transmission. According to the present invention, the turbine speed is assumed to be the same as the impeller or motor speed after the torque transmission through the automatic transmission has been interrupted. Under these conditions, very little slippage in the fluid coupling takes place and the turbine speed is equal to the impeller or motor speed to a sufficient accuracy. The synchronous turbine speed which determines when the jolt control is to be initiated and terminated is computed from the transmission output speed multiplied by the speed ratio between turbine and transmission output in the gear to be engaged.

Abstract: The signal initiating a reduction of engine torque during gear shift is derived from a monitoring of the engine speed. Specifically, the decrease in torque is initiated when engine deceleration, as determined by the negative speed gradient, exceeds a predetermined value. The torque decrease can, as preferred, take place only if a gear shift occurs, or it may take place independent of gear shift in which case high decelerations caused, for example, by rapid application of the brakes, also cause the decrease.
