Abstract: The disclosure is directed to a nutating action appliance in which the utilization device is driven directly by the wobble plate of a nutating action motor. A wobble plate (21) is contained within a motor housing (10, 11) and is driven with a nutating action by a controlled flow of fluid. An output shaft (28), rigidly secured to the wobble plate, extends out through the housing and is moved in an orbital manner as the wobble plate is driven through its nutating cycle. An ultimate contact-type utilization device (47) is driven directly by the output shaft and is activated with a highly efficient and useful motion, which is an orbital movement without rotation.
Patent EP-0003894-A1 (EP)
Title: Gear mounting
Inventor: HICKS RAYMOND JOHN
IPC: F16H57/08
Filed: 1979-02-16
Abstract: In a gear mounting having a spindle (2; 92,93) extending generally normal to a carrier (3; 90,91), the spindle is permitted limited radial excursions to adapt itself to the tooth loading. It is particularly suited to mounting planets in an epicyclic gear and the spindle may be cantilevered or straddle mounted. 
     Part, at least, of the spindle is axially prestressed and by the configuration and interengagement of the parts this holds the mounting in position. Under load, the stress is increased or imbalanced and the radial excursions are resisted. A cantilevered spindle comprises inner and outer members (5,7; 92,93) one being tensioned to compress the other, and it may either flex and/or change length by cam action with the carrier. In straddle mountings (90, 91), the spindle is under compression and locates against inclined surfaces which increases the axial load upon radial excursion.

Abstract: By providing a molded or extruded plastic base cylinder or plate with a surface coating of an etchable metal, a low cost printing media is achieved for use in intaglio or gravure printing. The plastic base cylinder may be machined to a low tolerance diameter before being substantially uniformly plated with an etchable metal such as copper or nickel about its entire outer peripheral surface, thereby assuring uniform balance and concentricity. The plated surface is then engraved or etched with the-information to be printed, resulting in a low cost printing cylinder for use in intaglio or rotogravure printing. In one embodiment, the cylinder incorporates a substantially uniform diameter shafting bore along its central axis in order to provide for mounting the cylinder on a shaft or other fixture, while another embodiment provides for accurately disposed and engaging lugs which rotationally drive the cylinder. In this way, uniform pressure resistance and complete peripheral surface concentricity and balance is achieved during the printing, engraving, plating, and polishing processes. Preferably, the plastic base comprises polypropylene, which may incorporate various fillers or resins for improving the plastic's physical characteristics.
