Patent number: 4739676Abstract: 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.Type: GrantFiled: May 28, 1985Date of Patent: April 26, 1988Assignee: Werner UllmannInventors: Werner Ullmann, Andre Mathys

Patent number: 4524623Abstract: A transducer drive assembly is disclosed having particular application for use in medical diagnostic imaging systems. The drive assembly includes a rotor coupled to drive means for rotation about its longitudinal axis. The rotor is formed such that it includes an integrally formed contact plate which extends upwardly from a generally flat rotor face at a given angle. A transducer is carried in a cradle which is mounted for pivotal movement, and includes a lower base portion having a generally cylindrical cross section. The lower base portion of the cradle is disposed such that it is maintained in physical contact with the rotor contact plate at all times. The rotation of the rotor applies force to the lower base of the cradle resulting in the oscillation of the cradle about the pivot points. The transducer is thereby oscillated back and forth about the pivot points in a uniform and continuous movement so long as the rotor continues to rotate.Type: GrantFiled: February 27, 1984Date of Patent: June 25, 1985Assignee: Diasonics, Inc.Inventor: Richard A.

Patent number: 4337854Abstract: A clutch pedal operated rod to the brake lever in a transmission brake system for tractors and the like is formed of two spaced longitudinally aligned rod lengths connected by a coupling for transmitting force therebetween through a fluid medium. The coupling is secured to the end of one length and slidable receives a spring loaded piston head on the aligned end of the other length. The piston head is in fluid seal engagement with the coupling and separates such coupling into an upper and lower chamber with a fluid supply disposed in the upper chamber in non-operating position. A fluid conduit exteriorly of the coupling communicates with both chambers. Depression of the clutch pedal effects relative movement of the piston head against the fluid supply in the upper chamber where the fluid acts as a solid member under pressure to transmit force to the brake operating rod for stopping the transmission.Type: GrantFiled: September 8, 1980Date of Patent: July 6, 1982Inventor: Jerry L.
