Abstract: A motion transmitting device incorporates a toothed wheel wherein each recess between any two consecutive teeth is a portion of an ovoid profile.The ovoid profiles of such toothed wheel interengaging with a series of ovoid holes formed on a datum plate indirectly through interconnecting meshing elements, thus providing motion-transmitting devices which may have multitooth engagement and thereby multitooth transmission of loads.

Abstract: A motion transmitting device including four basic elements, namely, eccentric means, meshing means formed from a number of meshing elements which are linked but movable independently with respect to each other, wheel means formed with portions adapted to engage said meshing elements, and movement limiting means, including a datum member, wherein said eccentric means is disposed to cause each of said meshing elements to become engaged with, and subsequently to become dissociated from, said portions, while said meshing elements are individually guided by said movement-limiting means within specific limits of movement relative to said datum member, such that always a plurality of adjacent ones of said meshing elements are simultaneously in driving engagement with, and stationary relative to, a corresponding number of said portions, and that the total movement relative to said datum member of each of said meshing elements, while it is drivingly engaged with one of said portions, follows a substantially ovoidal pa

Abstract: An audiovisual book system comprising an audiovisual apparatus accepting a book containing audiovisual pages, each page having an image and a sound track disposed near one of its edges and also having elongated perforations passing through binder means disposed in the book; individual pages, while they are retained and guided by the elongated perforations, are sequentially displaced, from their nesting position in the book, to a playing position, in which the sound track protrudes beyond one edge of the book and is thus exposed to a moving transducer in the apparatus, which scans the sound track arranged in the apparatus for scanning the sound track.In an alternative embodiment, the audiovisual book contains audiovisual sheets having two consecutive edges defining between them a missing area and an information track disposed about an axis which intersects this missing area.

Abstract: In an internal combustion engine, large droplets of heavy fuel are injected in the combustion chamber in the presence of excess air and preferably under low pressure. The mixture of excess air and droplets of fuel is compressed and thereby forced to pass at high velocity through a vortex throat (i.e. small orifice) into an ignition chamber, where the friction between droplets and air causes self-ignition of the surface layers of the droplets. The combustion gases force the burning droplets, through the vortex throat, back into the combustion chamber under high velocity, thereby the burning surfaces of the droplets continuously come in contact with fresh supplies of air, until they burn substantially completely.
