  • Torsional vibration damper with interleaf
    Patent number: 3945269
    Abstract: A torsional vibration damper for internal combustion engines. An annular inertia member is attached to a hub by an annular elastic member assembly having an interleaf. In one embodiment, the interleaf is thicker at the middle than at its ends. In another embodiment the interleaf is thinner at its middle than at its ends. The elastomer is radially deformed at different axial portions. Axial movement of the inertia member relative to the hub is inhibited, as is sliding out of the elastomer from the inertia and hub members.

  • Microfiche and reader
    Patent number: 3944350
    Abstract: A microfiche having one surface embossed or molded to define a multiplicity of small lenses (lensettes) integral with the microfiche. Each micro-image is stored directly below a corresponding lensette, thereby assuring optical distance registry between each micro-image and its projection. Lateral optical registry is also realized. In an embodiment, interlensette surface of the microfiche is made opaque to preclude optical cross-talk.
