  • Patent number: 9371193
    Abstract: A sorting conveyor having electromagnetically actuated rollers for sorting articles off one or both sides of the conveyor. A linear stator creates a magnetic flux wave that rotates rotors in the article-supporting rollers and selects their direction of rotation. In one version the magnetic flux wave swivels the rollers to change the sorting direction. In another version the magnetic flux wave causes one set of rollers or another set of orthogonally disposed rollers to contact conveyed articles.

  • Patent number: 6363845
    Abstract: According to a method of transferring a sheet through a working apparatus, a first sheet is moved by feed rolls partially into a working area of the working apparatus, which is followed by moving a second sheet by the same feed rolls to allow the leading end of the second sheet to be brought into abutment with the trailing end of its preceding first sheet and then to push the first sheet to a predetermined position within the working area. After the first sheet is thus placed and the second sheet is moved back out of the working area, the apparatus is operated to work the first sheet, for example, by pressing. The second sheet is moved forward into abutment with the trailing end of the worked first sheet and moved further while pushing the first sheet toward delivery rolls of the apparatus, which then removes the first sheet out of the working area of the apparatus. Such steps of operation is repeated to transfer a series of sheets successively through the working apparatus.

  • Patent number: 6360655
    Abstract: Residues are found to be stored in the compartments of a multiple container, located in homes, restaurants, cafeterias, etc. The residues thus classified are treated by the user himself who places the residues of the same type in the machine object of the invention, which will be another electrical appliance in homes and premises. The process consists of compacting each type of residue, forming briquettes with a spherical, cylindrical, prismatic shape, etc. formed in the compacting chamber of the machine. A binding material, such as a resin or the like and simultaneously a dye that indicates in accordance with a color code, the type of residue of the briquette, are injected on the briquette in a final stage. After polymerization and solidification, the briquettes are diverted automatically to a storage chamber for their subsequent transfer. The machine includes a compacting chamber with a side wall and another top wall movable by means of respective hydraulic cylinders.

  • Patent number: 5942081
    Abstract: A method and apparatus for bonding a cover (22) over the undulating surface of a foam cushion (10) by placing the foam cushion (10) on a tool (18), piercing the cushion (10) with a plurality of needles (44), lifting the needles (44) to lift the cushion (10) as the cushion is frictionally retained on the needles (44), heating ambient air and ejecting the hot air from the needles (44) and into the cushion to elevate the temperature of the cushion. A compression plate (58) with holes (60) extending therethrough is disposed against the backside of the cushion (10) with the needles (44) extending through the holes (60). The needles (44) with the cushion (10) thereon are lowered to place the undulating surface of the cushion against an adhesive film (82) on the backside of the cover (22) so that heat is transferred from the cushion (10) to melt the adhesive.
