| 61 | Sliding rack ratchet tensioner | US12523362 | 2008-01-11 | US08337345B2 | 2012-12-25 | Anand Arun Barve |
| The high-performance sliding rack ratchet tensioner is inexpensively manufactured. A rack having rack teeth is slidingly received in a rack slot on the side of the piston. The rack slot is preferably open-ended on the end facing the tensioner arm. The rack and piston are both received in a piston bore in the tensioner body. The rack length is preferably shorter than the rack slot length to provide backlash. A pawl mounted in a pawl bore perpendicular to the rack bore engages the rack. The open-ended rack slot allows the rack to be inserted after the piston during assembly. The rack and pawl preferably have shark fin-shaped teeth. The pawl preferably has dummy teeth to ensure that the load is shared by the center teeth. | ||||||

| 63 | Parking lock arrangement | US11846477 | 2007-08-28 | US08122786B2 | 2012-02-28 | Markus Kirchner |
| Locking arrangement for locking a first element which is movably mounted in a first direction, by means of a second element which is movably mounted in a second direction transversely with respect to the first direction. First element has a toothed contour with at least two teeth and a tooth gap which lies between. Second element has a projection which has a projection length which is shorter than the tooth gap length. The projection can be introduced into tooth gap when there is movement in the second direction, to lock the first element. Each tooth has a face which points towards the second element and has a first contour. Projection has a face which points towards the first element and has a second contour. First and second contours are matched to one another so that the projection is deflected by the teeth from becoming inserted into tooth gap if first element moves faster than a predetermined locking speed and slower than a maximum speed of first element. | ||||||

| 70 | Pull-Push Rod | US11665711 | 2005-10-19 | US20080115622A1 | 2008-05-22 | Albert Uhl; Francisco Gomez; Soeren Koch |
| The invention relates to a threaded device (7) embodied in the form of an anti-twisting stop which is rotatably connected to a traction-pressure rod. The inventive device comprises two oppositely located ratchet devices which are connected by a body enabling to stop the traction-pressure rod in several rotational positions with a predetermined locking force and, afterwards, to release it each time. Said threaded device (7) facilitates the mounting of the traction-pressure rod by the fact that the twisting should not be locked by additional handling, thereby making it possible to carry out a fine adjustment without additional measures. The ratchet device (4) comprises, for example, two ratchet elements (10, 11) provided with one or several catch lugs (12) or a metal or plastic ring part on one side and a gear rim on the other side. In addition, said threaded device can be provided with a spring element and a second anti-noise threaded device. | ||||||

| 78 | Drive for a machine for the manufacture of an electrode-workpiece by means of a form grinding tool of a similar spatial shape | US740836 | 1985-05-28 | US4739676A | 1988-04-26 | Werner Ullmann; Andre Mathys |
| A transmission is provided for a machine that manufactures a workpiece, later to serve as an electrode, by means of a form grinding tool. The tool has a similar spatial shape to that of the workpiece. The drive generates between the tool and the workpiece an orbital motion with changeable eccentricity and which orbital motion is necessary for a grinding or abrading process. A device, which can be structured as a transmission, an electrical control circuit, or as displaceable idling rollers, alters the eccentricity and is in constant operative connection with the driving side and power take-off side of the transmission. In this way there is obtained a constant setting or a cyclical adjustment of the eccentricity throughout the orbital movement. Furthermore, the orbital movement can describe non-circular patterns so that Lissajou patterns can be generated. | ||||||

| 80 | Two speed axle shift actuator | US725270 | 1985-04-19 | US4619151A | 1986-10-28 | Edward G. Trachman; Daniel W. Roper |
| A low power electric motor slowly load to spring, which rapidly operates a two speed axle shift. An electric motor drives a nonreversing worm gear which engages a gear rack on a shaft. The shaft supports a caged spring. The motor moves the shaft, compressing the spring against one end of the cage, storing energy required for shifting. A solenoid piston holds the cage in position. When the shift is desired, the soleniod is tripped, the piston is raised and the spring moves the cage. An arm on the cage moves the shift lever. The solenoid piston engages the opposite detent in the cage and holds the cage in the new position. As the cage arrives at the new position, a lug trips a microswitch which completes a circuit to operate the motor in the reverse direction. The motor worm slowly drives the gear which slowly drives the rack to move the shaft in the reverse direction, compressing the spring against the opposite end of the cage. When the shaft moves sufficiently to fully load the spring, a lug on the shaft trips the switch turning the motor off. The next pulsing of the solenoid causes the spring to drive the cage in the opposite direction, back towards its first position, where the solenoid locks the cage. A lug in the cage trips the switch, turning the motor on to run in a forward direction, driving the shaft to its original position and compressing the spring until a lug on the shaft engages a switch, turning the motor off. | ||||||
