Title: Machinery to move cars to and from storage location - has platform positioned by locking pieces between I-beams
IPC: E04H6/18
Filed: 1974-01-04
Abstract: The machinery moves loads, particularly vehicles, from a loading position to a platform moving in a vertical shaft, so that they can be lifted to storage locations.

Title: Resonance electric energy generation system - uses metal bar excited by UHF in accordance with unified field theory
IPC: H02N11/00
Filed: 1974-06-19
Abstract: The calculations concern electrical energy, created by an electrochemical system, where a small portion of the energy is reinjected to feed the system autonomously. The calculations, based on the unified field theory and electric field theory, concern the ejection of electrons from atoms by breaking the electron-nucleus bond by means of a uhf resonance frequency. The frequency is emitted onto a metal bar whence the atoms eject their electron in the form of an electron flux, producing a direct current, and thus recharging the battery.

Title: Cam and conical follower - has support shafts in bearings allowing shaft deflections
Inventor: MARTELLI FRANCOIS
IPC: F16H25/04
Filed: 1975-09-29
Abstract: A cam (1) and cam follower (3) are mounted on parallel shafts (2, 4) in shaft bearings (5) (6). The loads exerted on the cam shaft (4) and the cam follower shaft (2) cause the shaft axes to deflect away from each other. Rapid wear is obviated by making the cam follower slightly conical so that the half angle of the cone is equal to the angle between the axis of the shaft (2) and (4) at the plane (4) so that the working load is spread over the full width of the follower (3). The follower surface may also be made slightly convex to allow for variations in load.
