Abstract: The transmission member moves in a longitudinal direction of the input member to adjust a line b connecting an input central line (A) to an output central line (B) of the output shaft and a line a connecting a rotating central line (C) of the rotation shaft to the output central line (B) of the output shaft so that the lines a and b have the same length or lengths different from each other, thereby changing the rotational force of the input member to transmit the changed rotational force to the output member or transmitting the rotational force to the output member as it is.

Abstract: A continuously variable transmission (CVT) that does not depend on friction to transmit power. A constant and uniform output angular velocity can be achieved when the input angular velocity is constant and uniform by modifying the rate of change of angular displacement of the input disk using a set of non-circular gears. Co-axial input and output can also be achieved.

Abstract: A rotational driveshaft coupler that converts a rotating shaft motion into two orthogonal oscillations and at the opposite side of this coupler, a third oscillator converts the oscillations back to a rotational motion. At least one slip free seal can be constructed from the coupler to its housing to separate the space occupied by the output shaft from the space occupied by the input shaft. Each of the three oscillating motions can be guided by bearings, gears and tracks to reduce frictions and heat generation. Permanent magnet pairs are used to prevent bifurcation and force the output shaft to follow the rotation direction of the input shaft. Unlike in magnetic coupling, the torque transmission here is direct.

Abstract: An infinitely variable transmission (IVT) to provide a continuous output-to-input speed ratio from zero to a certain value is designed, and its working principle is illustrated. It is a geared IVT (GIVT), since its function to achieve the continuously varied speed ratio is implemented by gears. Crank-slider systems are used in the GIVT; the output-to-input speed ratio is changed with the crank length. Racks and pinions, whose motion is controlled by planetary gear sets, are used to change the crank length when the cranks are rotating. One-way bearings are used to rectify the output speeds from different crank-slider systems to obtain the output speed of the GIVT. Since the crank-slider systems can introduce variations of the instantaneous speed ratio, a pair of noncircular gears is designed to minimize the variations. A direction control system is also designed for the GIVT using planetary gear sets.

Abstract: A simple stepless variable transmission in which rotation of an input shaft (10) is translated into circular motion of an input stage arm (16) which is then converted into periodic rotation of an intermediate linkage (20) around a center of rotation that is displaced from the center of circular motion of the input stage arm (16). The periodic rotation of the intermediate linkage (20) drives an output stage arm (30) into periodic circular motion about a center that is displaced from the center of rotation of the intermediate linkage (20). An overrunning clutch (36) then transmits the useful portion of the periodic circular motion to an output shaft (37). Simultaneously controllably varying the distances between the centers of motion for the input stage arm (16), the intermediate linkage (20) and the output stage arm (30) controllably varies the ratio of the transmission.

Abstract: The invention realizes fluent drive without dead points by continuously cging the angle between the levers (13,14) of the pedals (1). The two pedal levers (13,14) are fixed to two separate shafts (15,16) with common axis (3). The driving shaft (18) is eccentric to this axis (3) and the mechanical connection between the driving shaft (18) and the shafts (15,16) of the pedal levers (13,14) is realized by eccentrics (19,20). With this construction the pedals move faster when coming upwards and slower when going downwards, so when the depressed pedal reaches its lowest point, the other one has already passed its highest point.

A pair of vacuum wheels alongside the path of the article on axes skewed slightly outwardly from the article path pull the wrapper down in front of the article and allow it to pass underneath as the article passes so that the wrapper becomes wrapped around the top, front and bottom of the articles.

Abstract: Apparatus for converting rotary motion from a source of power which may be of constant speed into a rectilinear force includes a coupling arrangement for driving an eccentrically unbalanced flywheel at a cyclically varying rotational speed and linkages for altering the timing of the cyclical variation of speed of the eccentrically unbalanced flywheel. The apparatus comprises a cam element which is driven at a constant rate of speed about an output axis which is perpendicular to its face. The cam element has a slot extending diametrically across its face, configured for slidably engaging a pin which is located on a cam follower. The cam follower is freely rotatable about an input axis that is offset from the output axis by an amount which allows the pin to remain in the slot when the elements are rotated. The cam follower in turn drives the flywheel at a cyclically varying rotational speed.

Abstract: Motion transmitting apparatus includes a case member, a pair of coaxial shaft members, and a pair of shuttle members. The members rotate about the shaft axis in unison as a differential mechanism, with differential action between the shaft members provided by oscillation and reciprocation of the shuttle members in opposite directions relative to another axis perpendicular to the shaft axis. Grounding the case member causes this opposite oscillation and reciprocation of the shuttle members to provide a reversal of the direction of rotation of the shaft members.

Abstract: A lost-motion drive mechanism is provided which is particularly, although not exclusively, adapted for use as a high speed transport for an X-ray film, or the like, in an X-ray camera. The drive mechanism includes an input shaft for coupling a drive motor to the drive shaft of the transport. Actuators are interposed between the input shaft and the drive shaft. As the input shaft is driven through one complete revolution (360.degree.) by the drive motor, the actuators cause the drive shaft to turn with an angular velocity which rises gradually from zero to a maximum for the first 180.degree. of rotation of the input shaft, and then with an angular velocity which decreases gradually from a maximum to zero for the next 180.degree. of rotation of the input shaft.

Abstract: A first drive apparatus for a thermoplastic web operates at an automatically adjusted, substantially constant, speed to deliver the thermoplastic web to a welding tool which rotates with a second pair of rollers. The second pair of rollers are driven at a cyclically variable speed in which the minimum speed is attained at the time when the welding tool is in contact with the thermoplastic web. An automatic control system adjusts the speed of the feed rollers to correspond to the speed of the welding tool at the instant during which welding is performed. Adjustment of the ratio of the maximum to the minimum speed of the cyclically variable speed of the second pair of rollers controls the length of thermoplastic web between welds without changing the speed of the driving input to the second pair of rollers.

Abstract: A gear reduction mechanism wherein a modification of the hypocycloidal principle is used. The planet gear of the hypocycloidal arrangement has at least one-half tooth more or less teeth than one-half the number of teeth on the ring gear. Either the ring gear or a pin reaction plate is permitted to rotate while the other is stationary. The reaction pins disposed on the planet gear travel in straight lines in slots formed in the reaction plate. When the reaction plate is stationary, the ring gear must rotate a very small amount during one complete rotation of the planet carrier to compensate for the tooth difference between the ring and planet gears. When the ring gear is held stationary, the reaction plate is forced to rotate to compensate for the tooth difference.

Abstract: The present invention relates to a variable-speed drive mechanism for the drum of an automatic sheet feeder.It is known that the collators for signatures and single sheets are provided with so-called automatic feeders which collate the material arranged in a pile on a collating table.In modern machines each feeder is provided with an aspirator for removing the lower sheet from the pile so that it can be gripped by the grippers fitted to each rotating drum. In the moment in which the sheet lifted by the aspirators is gripped by the grippers, the drum must stop to allow the perfect gripping of the single sheet.
